Microsoft Defender XDR is a comprehensive cybersecurity solution designed by Microsoft to protect organisational networks and devices. At its core are the Attack Surface Reduction (ASR) rules, which are strategic security protocols aimed at minimising the vulnerabilities and pathways exploited by cyber threats. These rules act as a crucial line of defence, shielding endpoints from various attack vectors such as malicious documents, scripts, and other potentially harmful activities. However, despite their importance in fortifying cybersecurity defences, recent scrutiny has uncovered a critical vulnerability within these ASR rules. This vulnerability poses a significant risk as it allows adversaries to bypass established security measures without triggering alerts or raising suspicion, thereby compromising the effectiveness of Microsoft Defender XDR’s defence mechanisms.

Regrettably, a remedy for this issue is not yet available*. Consequently, recourse to Advanced Hunting queries armed with Custom detection rules becomes imperative to diligently monitor for any indicators of compromise, thereby mitigating potential risks.

* Table 1: BUI researchers logged two notices via the Microsoft Security Response Center. The details are included here in Table 1.

Critical Vulnerability explained

Attack Surface Reduction (ASR) rules are configured on devices by means of a registry key. The contents of this key include the GUID for the specific ASR rule as well as the state of the rule (Block, Audit).

The registry key is not protected and can be modified without triggering any alerts, essentially bypassing ASR rules, which could result in negation of the protection.

Registry Key:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager\ASR Rules

Critical Vulnerability demonstrated

By following the steps below, ASR rules can be bypassed. The rule Block all Office applications from creating child processes will be tested.

Bypassing ASR rules:

  1. Launch an elevated PowerShell session and run the following commands to confirm that ASR rules are configured:

       Get-MpPreference | Select-Object -expandproperty AttackSurfaceReductionRules_Ids

       Get-MpPreference | Select-Object -expandproperty AttackSurfaceReductionRules_Actions

  1. Navigate to the following registry hive:

       Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager\

  1. Open the following registry key:

       ASR Rules

  1. Delete the contents of the registry key.
  2. Rerun the following commands in an elevated PowerShell to confirm that the ASR rule configuration has been removed:

       Get-MpPreference | Select-Object -expandproperty AttackSurfaceReductionRules_Ids

       Get-MpPreference | Select-Object -expandproperty AttackSurfaceReductionRules_Actions

Testing the bypass:

  1. Create a simple bat file to create a folder.

       Example: Mkdir “c:\tools\new folder”

  1. Launch Microsoft Word.
  2. Enable the Developer Tools tab on the Ribbon.
  3. Create a new Macro and edit the Macro in Visual Basic.
  4. Enter the following code:

       Sub [your Macro name] ()

       Dim str As String

       Str = “cmd.exe /C [location of bat file]

       shell str, vbMaximizedFocus

       End Sub

       Example shown here in screenshot:

  1. Run the Macro and verify that a folder has been created. See screenshot:

The successful creation of a folder indicates that ASR rules have been successfully bypassed.

Running the same Macro without bypassing the ASR rules results in the following alert:

Mitigation strategies

By determining the current ASR policy configuration and monitoring for any changes to this configuration, Advanced Hunting queries with Custom detection rules can act as a potential mitigation strategy until this critical vulnerability is remediated.

  1. Determine the current configuration by viewing the following registry key:

       Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager\ASR Rules

  1. Within Microsoft Defender XDR, run the following Advanced Hunting Query:

       DeviceRegistryEvents

       | where RegistryKey has “HKEY_LOCAL_MACHINE”

       and RegistryKey has “SOFTWARE”

       and RegistryKey has “Microsoft”

       and RegistryKey has “Windows Defender”

       and RegistryKey has “Policy Manager” or

       RegistryKey contains RegistryValueName == “ASRRules” and RegistryValueData != PreviousRegistryValueData and RegistryValueData != “ [Enter your registry key value here]

  1. From the Advanced Hunting query, create a Custom detection rule. 
  1. Configure the Alert details, Impacted Entities, Actions as required.

       Suggested configurations:

       Frequency: Every hour

       Impacted Entity: Device | Device ID

       Actions: Run antivirus scan

Once configured, the Custom detection rule will run once every hour and generate an alert for all devices in which the ASR rule registry key has changed.

Any alerts should be investigated as running a Microsoft Defender Antivirus scan alone will not be a sufficient response.

It is important to note that the registry key in the Advanced Hunting query should be updated after any change is made to the ASR rules.

Copilot for Microsoft 365: Key news updates to know

In Part 1 of our Copilot for Microsoft 365 spotlight series, Cloud Security Architect Neil du Plessis unpacks the news you need to know about this AI-powered assistant for the modern workplace.

BUI Becomes a 2024 Data Privacy Week Champion

This year’s initiative emphasises educating businesses on data collection best practices that respect data privacy and promote transparency

BUI announced its commitment to Data Privacy Week 2024 by registering as a Champion. As a Champion, BUI recognises and supports the principle that all organisations share the responsibility of being conscientious stewards of personal information. Data Privacy Week is an annual expanded effort from Data Privacy Day – taking place from 21st – 27th of January 2024. The goal of Data Privacy Week is to spread awareness about online privacy among individuals and organisations. The goal is twofold: to help citizens understand that they have the power to manage their data and to help organisations understand why it is important that they respect their users’ data.

How To Prioritize Data Privacy With Your Customers

The US National Cybersecurity Alliance (NCA) recommends adopting the following market leading practices:

  • Be transparent about how you collect, use, and share consumers’ personal information.
  • Think about how the consumer may expect their data to be used.
  • Design settings to protect their information by default.
  • Communicate clearly and concisely to the public what privacy means to your organization, as well as the steps you take to achieve and maintain privacy.

Engage the experts

Remember that most employees aren’t privacy or security experts. You will need to build in mechanisms that make it easy for them to report privacy and security concerns to your experts. Just like tools for preventing privacy incidents are critical, tools that easily empower employees to report are necessary in your company’s privacy toolbox, too.

Outsourcing to professional cybersecurity companies takes a load off your plate and ensures you have the data protection you deserve.

Take Control of your data

All your online activity generates a trail of data. Websites, apps, and services collect data on your behaviours, interests, and purchases. Sometimes, this includes personal data, like your Social Security and driver’s license numbers. It can even include data about your physical self, like health data – think about how a smartwatch counts and records how many steps you take.

While it’s true that you cannot control how each byte of data about you and your family is shared and processed, you are not helpless! In many cases, you can control how you share your data with a few simple steps. Remember, your data is precious, and you deserve to be selective about who you share it with!

Follow these steps to better manage your personal information and make informed decisions about who receives your data.

About Data Privacy Week

Data Privacy Week began as Data Privacy Day in the United States and Canada in January 2008 as an extension of the Data Protection Day celebration in Europe. Data Protection Day commemorates the 28th of January 1981, signing of Convention 108, the first legally binding international treaty dealing with privacy and data protection. NCA, the nation’s leading nonprofit, public-private partnership promoting cybersecurity and privacy education and awareness, leads the effort in North America each year.

BUI supports global security awareness campaign

BUI supports global security awareness campaign

BUI is proud to participate in Cyber Security Awareness Month as a Champion Organisation for the sixth consecutive year. Founded in 2004, Cyber Security Awareness Month (held each October) is the world’s foremost initiative aimed at promoting cyber security awareness and best practices. The campaign is a collaborative effort among businesses, government agencies, colleges and universities, associations, non-profit organisations, communities and individuals to educate others about online safety.

“Knowledge and vigilance are essential when it comes to cyber security,” says BUI Global CEO Ryan Roseveare. “You need to know what to look out for. You need to know what to do when you see a red flag. And you need to be alert whenever you’re online. Cyber Security Awareness Month plays a key role in educating the public about common cyber risks and encouraging everyone to become more vigilant. BUI is pleased to join the international community in this focused effort to improve cyber security awareness worldwide.”

From smartphones to web-enabled home devices, technology is deeply intertwined with our lives. And while the evolution of technology accelerates, cybercriminals are working just as hard to find ways to compromise technology and disrupt our personal and business activities.

Cyber Security Awareness Month aims to highlight some of the emerging challenges that exist in the world of cyber security today and provide straightforward, actionable guidance which anyone can follow to create a safer, more secure digital world for themselves and their loved ones.

Starting this year, the new theme of Cyber Security Awareness Month is Secure Our World. The main messaging revolves around four cyber security practices:

  1. Creating strong passwords and using a password manager. The strongest passwords are long and unique, with a mixture of character types (lowercase letters, uppercase letters, numbers, and symbols).
  2. Enabling multi-factor authentication whenever possible. Multi-factor authentication, or MFA, adds an extra layer of security to digital accounts by making secondary authentication mandatory.
  3. Recognising and reporting phishing. Public awareness is essential as cybercriminals continue to refine their tactics for phishing scams conducted through emails, text messages, chats, and phone calls.
  4. Keeping software updated. The latest updates and security patches are important to install to ensure that operating systems, internet browsers, and applications are safeguarded.
  5. Cyber Security Awareness Month continues to build momentum and impact with the goal of providing everyone with the information they need to stay safe online. BUI is proud to support this far-reaching online safety awareness and education initiative, which is co-managed by the Cyber Security and Infrastructure Security Agency (CISA) and the National Cyber Security Alliance.

    For more information about the 2023 Cyber Security Awareness Month campaign, you can visit the CISA and Stay Safe Online websites. You can also follow BUI on LinkedIn, Facebook and X (formerly Twitter) for helpful tips and resources throughout October, and join the global conversation by including the hashtag #CyberSecurityAwarenessMonth in your own social media posts.

Practical pointers to help you improve workplace data security

Businesses that take a proactive approach to cybersecurity are better equipped to safeguard sensitive data and spot suspicious activity.

Keeping sensitive data safe and secure is a challenge for businesses of all sizes. Major shifts in the workplace – from in-person to remote and hybrid productivity – forced companies to change, or at least re-assess, their cybersecurity practices and protocols. And far too often, they were not adequately prepared for the evolving cyberthreat landscape.

In fact, according to CyberEdge’s ninth annual Cyberthreat Defence Report, more than 80% of organisations suffered from a successful cyberattack in 2021. With data privacy and data security top of mind, businesses are looking to strengthen their defences against cybercriminals. Here are four simple steps you can take to better protect your workplace data.

1 | Identify the ‘crown jewels’ of your business

Knowing what kind of data cybercriminals want is an essential part of your defence strategy. Therefore, creating an inventory of your so-called crown jewels (the most valuable data and data-related assets within your organisation, including hardware and software information) is important.

In addition, you should have a current (and actively maintained) list of every end-user who has access to your critical business data. Keep accurate records, with device and location details, so that you can carry out the necessary forensic investigations in the event of a data breach.

 2 | Make sure you’re updating and authenticating – always

Keep your operating systems, software packages and web browsers up to date and ensure that all devices have automatic updates enabled. When your connected environment is well maintained, with patches and updates carried out timeously, then your overall security posture is that much stronger.

In addition, make sure that your staff use multifactor authentication (MFA) when they log in. Simple username-and-password combinations are not enough to keep cybercriminals at bay, and MFA could mean the difference between a successful or an unsuccessful hack.

3 | Actively monitor your connected environment for suspicious activity

You should monitor your IT environment continuously to detect misconfigurations, vulnerabilities, breach attempts, and cyberattacks in real time. If you have dedicated cybersecurity personnel, they can implement endpoint security technology to help monitor your network. If not, you can bring in SecOps experts to actively identify, investigate, and mitigate cyberthreats 24/7/365.

Moreover, make sure that everyone in your organisation understands the importance of good cyber hygiene and is following the security policies you have in place. When your people know how to spot phishing attempts, for example, then they can respond appropriately.

4 | Prepare your response plan in advance

No matter how many safeguards you have in place, the unfortunate reality is that cyber incidents still occur. However, responding in a comprehensive manner will reduce the impact on your business and send a positive signal to your customers and employees. Therefore, you should have an incident response plan prepared in advance.

This document should be stored safely and your dedicated response team should be able to access it quickly when the need arises. Make sure your incident response plan includes clearly defined technical, operational, legal, and communication-related steps for your team to follow.

Three ways to improve your household cybersecurity

Your home network is your gateway to the internet. Are you taking appropriate measures to protect your connected household from cyberattackers?

The COVID-19 pandemic forced people to embrace working from home – a concept they had little or no experience with at the time. Many employees have since returned to the office, but remote work remains a popular choice. According to the 2022 State of Remote Work report by Buffer, 97% of remote workers would like to work remotely, at least some of the time, for the rest of their careers. As remote and hybrid work models continue to evolve, it’s vital for households to be vigilant about cybersecurity.

Most households are linked to the internet in some way. They can be hard-wired to the net or they can leverage wireless technology to connect computers, gaming systems, TVs, tablets, mobile phones and smart home devices to the worldwide web. Having the right cyber protection in place is essential to ensure that everyone in the home can use the internet safely and securely for personal and professional activities. Here are three simple ways to improve your household cybersecurity.

1 | Secure your wireless router

Using a wireless router is a convenient way to allow multiple devices to connect to the internet from different areas of your home. However, unless your router is secure, you risk the possibility of outsiders accessing information on your devices or using your network for nefarious purposes.

It’s important to secure your router from Day 1. Manufacturers assign preset passwords to routers – and these defaults are often weak or easy to guess. If you leave the factory-set password in place, then you effectively leave the door open for cybercriminals to breach your home network. Make sure you change the default router password when you set up the machine itself.

2 | Install security software on household devices

All devices connected to your home network should have security software installed – and updated regularly. Many modern devices have automatic update features, and you should enable them to ensure that your gadgets function optimally and securely at all times.

With the most up to date security software, operating systems and web browsers, your household devices will be better protected against viruses, malware and other cyberthreats.

3 | Back up household data

While steps can be taken to reduce the chance of your household network, devices and user accounts being hacked or compromised, they can never be 100% effective. Households should embrace the practice of backing up data.

You can protect your valuable work, photos and other digital information by making electronic copies of important files and storing them safely. This can be done using cloud software in addition to manual storage devices like portable hard drives and USBs.

By taking simple, proactive steps like these in your own home, you can defend your household members against online fraudsters and scammers.

Four basic online safety tips to remember

If you look out for phishing scams, protect your passwords, and update your devices regularly, then you can improve your online safety.

Cybersecurity has become one of the biggest topics inside and outside of technology circles over the past two years. From securing personal devices for digital learning and remote work during the COVID-19 pandemic to safeguarding corporate data against cyberattacks, there’s been a seemingly endless news cycle dedicated to concerns around online safety.

It’s easy to feel overwhelmed or even powerless in the face of rapidly increasingly cybercrime, especially when there are fresh headlines about data breaches and phishing scams almost every day. But end-users – the people using technology to communicate, collaborate and connect – have an important role to play as the first line of defence when it comes to thwarting scammers, fraudsters and threat actors.

Unfortunately, many individuals are not aware of the most basic cybersecurity practices for everyday life. During Cybersecurity Awareness Month this October, Champion organisations like BUI are trying to change that – by sharing practical, actionable tips to help everyone #BeCyberSafe. Here are four basic online safety tips that you can implement right now.

1 | Watch out for phishing scams

Phishing (when a cybercriminal poses as a legitimate party in the hope of getting individuals to engage with malicious content or links) remains one of the most popular tactics among cybercriminals. In fact, about 90% of data breaches occur due to phishing, according to Cisco’s 2021 Cybersecurity Threat Trends report.

While phishing has grown more sophisticated, suspicious email characteristics (like poor spelling and grammar, typos, low-quality graphics and fake logos in a message) can be a tell-tale sign that the content is risky. Read our explainer blogs – Phishing: Can you spot these common types? and Three ways to shore up your defences against phishing – to learn more.

And remember… If you think you have spotted a phishing attempt, be sure to report the incident to your internal IT teams and service providers so that they can remediate the situation and prevent others from possibly becoming victims.

2 | Protect your passwords

Having a unique, long and complex password for each of your accounts is one of the simplest ways to boost your online safety. And yet, only 43% of the public say that they “always” or “very often” use strong passwords, according to the National Cybersecurity Alliance’s 2022 Cybersecurity Attitudes and Behaviours Report.

Password cracking is one of the go-to tactics that cybercriminals turn to in order to access sensitive information. And if you are a “password repeater”, once a cybercriminal has hacked one of your accounts, they can easily do the same across all of your accounts. Read our blog – The importance of digital identity management – to find out why it’s vital to make your login credentials rock solid.

3 | Enable multifactor authentication

Multifactor authentication or MFA – which prompts a user to input a second set of verifying information or to sign-in via an authenticator app – is a very effective measure that anyone can employ to reduce the chances of a cybersecurity breach.

According to Microsoft, MFA can block over 99.9% of account compromise attacks. Therefore, it is a must for any individual who is looking to secure their devices and accounts. Remember, multifactor authentication – from one-time PINs to biometric scans – will put an extra barrier between your sensitive data and the cybercriminals who want to access it.

Read our blog – Three simple ways to improve your data privacy – to explore other ways of protecting your personal information.

4 | Turn on automatic updates

Making sure that your devices are up to date should be an essential part of your cybersecurity routine. Don’t ignore software updates and patches! Cybersecurity is an ongoing effort, and updates are important for device maintenance and security.

Instead of trying to remember to check for updates, enable automatic updates whenever you can. This way, you’ll reduce your chances of having older, possibly vulnerable or risky versions of software that could be exploited by cybercriminals.

Phishing: Can you spot these common types?

On the cybercrime timeline, phishing dates back to the mid-1990s when hackers exploited one of the earliest internet service providers to steal passwords and credit card data from unsuspecting users. Technology has evolved significantly since then, but phishing remains a popular attack method because it’s specifically designed to take advantage of human nature.

What is phishing?

Phishing is the practice of using fake, fraudulent, or deceptive communication to lure or convince a targeted person (or group) to hand over sensitive information.

Cybercriminals pretend to be legitimate, trustworthy sources and contact their victims by email, phone, or SMS with the goal of acquiring anything from personal data and banking details to usernames and passwords.

The scammers then leverage the newly acquired information for their own illicit purposes, which may include identity theft, credit card fraud, or privileged account access, among other things.

Email phishing, spear phishing, whaling, smishing, and vishing are five common types of phishing attacks. Learn to recognise the warning signs so that you’re less likely to be fooled by a scam message.

#1 | Email phishing

Email phishing (also called deception phishing or deceptive phishing) is perhaps the most well-known type of phishing. In this kind of scam, attackers impersonate a real company, organisation, or group and send out mass emails to as many email addresses as they can find. This so-called “spray and pray” approach is a numbers game for the perpetrators, and even if they only hook a handful of victims, the attack may still prove worthwhile and lucrative.

How do they do it? The scam email message is intended to make you perform an action, like downloading an attachment or clicking on a link. Malware embedded inside the attachment is activated when you open the file, and the link destination is often a malicious website primed to steal your credentials or install nefarious code on your device.

Consider this example… You receive a legitimate-looking email from your streaming service, saying your account has been temporarily suspended because of unusual activity. You’re instructed to click on a link inside the email, to verify your account credentials. You expect to be directed to the streaming service’s login page, but the link actually takes you to a lookalike login page that harvests your username and password.

#2 | Spear phishing

Spear phishing takes the concept of email phishing and applies it to a specific individual or group. Instead of the bulk, generic communication associated with regular email phishing, spear phishing involves customised messaging for a selected target. As the name implies, spear phishing is a pointed attack, not a wide-net manoeuvre, and scammers will often leverage publicly available corporate collateral to fine-tune the elements of their email trap.

How do they do it? Detailed, personalised messaging is key to the success of any spear-phishing campaign – because the attackers have to make you, the recipient, trust them enough to do what is asked in the email. They may spend days or even weeks on research and information-gathering (from your company’s website, social media pages, and published reports) as part of their efforts to trick you into action.

Consider this example… You’re the accounting clerk responsible for processing vendor invoices. You receive an email from an unknown vendor, with a PDF invoice attached. The message is well-written and friendly. The email sender knows your name and is knowledgeable about your company; they even send their best wishes to your colleague, John, whose motorcycle accident was addressed in your company newsletter last week. You believe that the vendor is legitimate and open the attachment, which then delivers malware to your laptop.

#3 | Whaling

Whaling (also called whale phishing) is the term used to describe phishing attacks aimed at a company’s most senior, most connected, or most influential leaders – the whales. The chief executive officer, chief operating officer, chief financial officer, chief technology officer, and other senior managers are attractive targets because of their high-level access to company resources. With an executive’s login credentials in their possession, scammers may be able to transfer corporate funds, expose private data, or impersonate the target to disrupt or damage the business.

How do they do it? Like spear phishing, whaling requires a tailored approach. Cybercriminals may have to profile the chosen individual for months to gain sufficient insight into their personal and professional lives. But as soon as the phishers have enough information, they can create believable, persuasive messages to try to deceive their victims into downloading malicious files or visiting compromised websites.

Consider this example… A new email lands in your inbox – and it’s from a law firm. The subject line and the content of the message imply that your company is being sued for millions by a former employee. The preliminary paperwork is attached to the email. As the chief legal officer, it’s your responsibility to investigate – but you don’t realise that the attachment is tainted.

#4 | Smishing

Smishing (also called SMS phishing) uses a text message rather than an email message to conduct a phishing attack, but the rationale is the same: scammers want to fool you into clicking on a risky link, downloading a malicious application, or surrendering your personal information.

How do they do it? Digital fraudsters take advantage of the fact that you keep your smartphone within reach and probably read your text messages soon after they arrive. And, as with other phishing methods, deception is their key tool. By masquerading as bona fide businesses (like your supermarket) or trusted sources (like your bank), they can deliver compelling texts directly to you – quickly, easily, and more than once.

Consider this example… You receive an SMS offering 20% off your next clothing purchase.

#5 | Vishing

Vishing (also called voice phishing or phone phishing) is when scammers call you directly – on your home landline, your work phone, or your cell – and try to make you give out personal or corporate information. Often, they will exploit annual trends and public concerns, or create a sense of panic that makes you feel compelled to comply with their requests.

How do they do it? The person making the fraudulent phone call may pretend to be a tax official who needs your company registration number for verification before refunding money to you. They may claim to be a health official calling to put you on the list for a COVID-19 vaccination. They may even claim to be a customer service agent from your bank, alerting you to suspicious withdrawals from your account. In every scenario, the phisher on the other end of the line will do their utmost to extract sensitive information from you.

Consider this example… You’re called by someone who claims to be from an insurance firm. They say that you’ve been named as a beneficiary in the estate of their deceased client, and you stand to receive a substantial sum of money if you can verify your identity in line with the facts in their possession. You may be asked for your full name, your ID number, your physical address, and your other phone numbers as the impersonator tricks you into providing confidential, high-value information over the phone.

These five types of phishing attacks are among the most prevalent, but they’re not the only ones used by cybercriminals. You need to be able to spot the tactics (and teach your teams to spot them, too) so that would-be phishers do not succeed when they target you and your staff.

Five questions to ask your leadership team before the POPIA grace period ends

South Africa’s Protection of Personal Information Act gives individuals more control over how their personal information is collected, processed, and used by private and public bodies. The Act requires such bodies (AKA responsible parties) to meet several minimum requirements for the lawful processing of data – and the grace period is almost over. From 1 July 2021, SA organisations must be compliant. Are you ready? Ask your leadership team these five questions to check that key areas of accountability have been addressed…

1 | Do we have a registered Information Officer?

As a responsible party, you are required to register your Information Officer with the Information Regulator by 1 July 2021.

You can do this online via the Information Officer Registration Portal on the Information Regulator’s website, where electronic and PDF versions of the registration form are available. The portal also contains relevant documentation, including guidance notes, official notices, and policies.

Remember, your Information Officer (IO) is the person responsible for making sure your organisation adheres to POPIA. They need to encourage and ensure your organisation’s compliance with POPIA, deal with any information access requests pursuant to the legislation, and work with the Information Regulator in relation to any investigations conducted in terms of POPIA.

They also need to see to it that an organisational compliance framework is developed, implemented, monitored and maintained, and that internal awareness sessions are conducted regarding the provisions of the Act, among other duties. The IO’s responsibilities are listed in Section 55 of POPIA and in the POPIA Regulations.

2 | Do we have adequate security measures in place?

As a responsible party, you are required to secure the integrity and confidentiality of personal information in your possession or under your control.

According to Section 19 of POPIA, this includes the implementation of “appropriate, reasonable technical and organisational measures” to prevent loss of, damage to, or unauthorised destruction of personal information.

Whether you manage personal data on paper or online, POPIA calls for you to identify all reasonably foreseeable internal and external risks to the data; establish and maintain appropriate safeguards against the risks identified; regularly verify that the safeguards are effectively implemented; and ensure that the safeguards are continually updated in response to new risks.

In addition, POPIA decrees that you must have “due regard to generally accepted information security practices and procedures” which may apply to you generally, or which may be required in terms of specific industry or professional regulations (e.g., hospitals are expected to have strict security measures in place to protect the detailed, sensitive medical records of their patients).

3 | Do we know what to do in the event of a data breach?

As a responsible party, you are required to report security compromises to the Information Regulator and the data subject(s) involved as soon as reasonably possible.

Section 22 of POPIA describes the obligations of the responsible party when there are “reasonable grounds” to believe that the personal information of a data subject has been accessed or acquired by an unauthorised person.

You should have a comprehensive incident response plan on hand to guide your actions in the event of a data breach, data leak, or cybersecurity incident. Make sure that your IO and key members of your leadership team follow a systematic process to identify the incident, respond appropriately, escalate where necessary, and communicate clearly in line with POPIA’s stipulations.

If you fail to notify data subjects in such circumstances, you could face imprisonment, fines, or both. Remember, you must notify affected parties in writing as soon as reasonably possible after the discovery of a security compromise.

4 | Do we have employee training initiatives in place?

As a responsible party, you should ensure that your employees are educated about basic information security protocols and procedures.

From your Human Resources Department, which handles sensitive staff info, to your employees themselves, who may manage personal data from customers, suppliers, and service providers, your teams have to deal with personal information on a regular basis.

Make sure everyone in your organisation is familiar with POPIA’s requirements – and that individual staff members, line managers, and department heads understand their duties and responsibilities when it comes to data processing, data management, and data security.

Educate your personnel about the collection, use, and storage of personal information under POPIA, and remember that they may need specialised training for new systems and new productivity tools deployed now, or in the future.

5 | Do we understand the risks of non-compliance?

As a responsible party, you could face hefty fines or imprisonment if you’re found to be in contravention of the law.

There are civil and criminal consequences for non-compliance with POPIA. Section 99 of the Act describes how a data subject (or the Information Regulator, at the request of a data subject) may institute civil action against a responsible party for breach of POPIA.

Offences, penalties, and administrative fines are outlined in Chapter 11 of the legislation. If you are convicted of an offence in terms of POPIA, you could be fined up to R10-million, or imprisoned for up to 10 years.

Non-compliance also poses a risk to your reputation: public trust in your organisation could be eroded overnight if you suffer a data breach, and serious brand damage could cripple your business irrevocably.

BUI selected to join Microsoft Intelligent Security Association

We are pleased to announce that we have joined the Microsoft Intelligent Security Association (MISA), a global ecosystem of independent software vendors and managed security service providers that have integrated their solutions to help customers better defend against a world of evolving cybersecurity threats.

MISA was launched in 2018 with 26 members. Today, just over 160 industry leaders from across the international cybersecurity spectrum work together to share threat intelligence, extend solution capabilities, and increase customer protection.

MISA membership is by invitation only. Organisations must be nominated by Microsoft, and must demonstrate integrations that support the goal of improving enterprise security. We were selected to join the association as a managed security service provider, for our NettProtect vulnerability scanning solution and turnkey add-ons to our Cyber SoC packages, as well as our Microsoft Defender for Endpoint managed service, which is geared to reinforce network security through next-generation detection, investigation, and threat-hunting.

“We are very proud to be part of the Microsoft Intelligent Security Association,” says Managing Director Ryan Roseveare. “Our MISA membership not only deepens our longstanding relationship with Microsoft, but also opens the door for our specialists to collaborate with some of the top security professionals in the world. We are excited to share our expertise with our new peers. And we look forward to delivering even more value to our customers, through innovative security offerings that meet their business needs.”

The BUI Cyber Security Operations Center (Cyber SoC) integrates with Microsoft Azure Sentinel, a cloud-native, AI-based security information and event management solution, to make threat detection and response smarter and faster. The state-of-the-art facility is the first of its kind in Africa, and harnesses Microsoft security resources to monitor enterprise networks, servers, endpoints, databases, and applications.

“The success of our Cyber SoC lies in the combination of cutting-edge technology and industry-leading skills,” declares Roseveare. “We have created a compelling solution by reducing the cost and complexity of managed security services, and by giving our customers value-driven add-ons, like our Cyber SoC Panic Button for emergency assistance,” he notes.

“The Microsoft Intelligent Security Association has grown into a vibrant ecosystem comprised of the most reliable and trusted security software vendors across the globe. Our members, like BUI, share Microsoft’s commitment to collaboration within the cybersecurity community to improve our customers’ ability to predict, detect, and respond to security threats faster,” says Rani Lofstrom, Senior Product Marketing Manager, Microsoft Security.

BUI’s MISA membership follows several company milestones in 2020. Since the beginning of the year, we have achieved Microsoft Azure Expert Managed Service Provider status and attained advanced specializations in Adoption and Change Management and Windows Virtual Desktop. We have also been named Microsoft Country Partner of the Year, Microsoft Modern Workplace Partner of the Year, Microsoft Azure Infrastructure Partner of the Year, and Microsoft Security Partner of the Year.

“We are determined to help our customers strengthen their cyber defences in the face of increasingly sophisticated threats,” says Roseveare. “As part of MISA, we are now even better positioned to empower organisations to protect their assets – from identity to infrastructure, and from the edge to the cloud,” he concludes.
