How to Use Threat Modelling to Reduce Your Cybersecurity Risk

Tanya Wetson-Catt • Jul 20, 2023

As cyber threats continue to increase, businesses must take proactive steps. They need to protect their sensitive data and assets from cybercriminals. Threats to data security are persistent and they come from many different places. 


Today’s offices are digitally sophisticated. Just about every activity relies on some type of technology and data sharing. Hackers can breach these systems from several entry points. This includes computers, smartphones, cloud applications, and network infrastructure.


It’s estimated that cybercriminals can penetrate 93% of company networks.


One approach that can help organizations fight these intrusions is threat modelling.


Threat modelling is a process used in cybersecurity. It involves identifying potential threats and vulnerabilities to an organization's assets and systems.


Threat modelling helps businesses prioritize their risk management and mitigation strategies. The goal is to mitigate the risk of falling victim to a costly cyber incident.


Here are the steps businesses can follow to conduct a threat model.


Identify Assets That Need Protection


The first step is to identify assets that are most critical to the business. This includes sensitive data, intellectual property, or financial information. What is it that cybercriminals will be going after?


Don’t forget to include phishing-related assets. Such as company email accounts. Business email compromise is a fast-growing attack. It capitalizes on breached company email logins.


Identify Potential Threats


The next step is to identify potential threats to these assets. Some common threats could be cyber-attacks such as phishing. Others would be ransomware, malware, or social engineering.


Another category of threats could be physical breaches or insider threats. This is where employees or vendors have access to sensitive information.


Remember, threats aren’t always malicious. Human error causes approximately 88% of data breaches. So, ensure you’re aware of mistake-related threats, such as:


  • The use of weak passwords
  • Unclear cloud use policies
  • Lack of employee training
  • Poor or non-existent BYOD policies


Assess Likelihood and Impact


Once you've identified potential threats, take the next step. This is to assess the likelihood and impact of these threats. Businesses must understand how likely each threat is to occur. As well as the potential impact on their operations, reputation, and financial stability. This will help rank the risk management and mitigation strategies.

Base the threat likelihood on current cybersecurity statistics. As well as a thorough vulnerability assessment. It's best this assessment is by a trusted 3rd party IT service provider. If you’re doing your assessment with only internal input, you’re bound to miss something.


Prioritize Risk Management Strategies


Prioritize risk management strategies next. Base this on the likelihood and impact of each potential threat. Most businesses can’t tackle everything at once due to time and cost constraints. So, it’s important to rank solutions based on the biggest impact on cybersecurity.


Some common strategies to consider include implementing:


  • Access controls
  • Firewalls
  • Intrusion detection systems
  • Employee training and awareness programs
  • Endpoint device management


Businesses must also determine which strategies are most cost-effective. They should also align with their business goals.


Continuously Review and Update the Model


Threat modelling is not a one-time process. Cyber threats are constantly evolving. Businesses must continuously review and update their threat models. This will help ensure that their security measures are effective. As well as aligned with their business objectives.


Benefits of Threat Modelling for Businesses


Threat modelling is an essential process for businesses to reduce their cybersecurity risk. Identifying potential threats and vulnerabilities to their assets and systems is important. It helps them rank risk management strategies. As well as reduce the likelihood and impact of cyber incidents.


Here are just a few of the benefits of adding threat modelling to a cybersecurity strategy.


Improved Understanding of Threats and Vulnerabilities


Threat modelling can help businesses gain a better understanding of specific threats. It also uncovers vulnerabilities that could impact their assets. It identifies gaps in their security measures and helps uncover risk management strategies.


Ongoing threat modelling can also help companies stay out in front of new threats. Artificial intelligence is birthing new types of cyber threats every day. Companies that are complacent can fall victim to new attacks.


Cost-effective Risk Management


Addressing risk management based on the likelihood and impact of threats reduces costs. It can optimize company security investments. This will help ensure that businesses divide resources effectively and efficiently.


Business Alignment


Threat modelling can help ensure that security measures align with the business objectives. This can reduce the potential impact of security measures on business operations. It also helps coordinate security, goals, and operations.


Reduced Risk of Cyber Incidents


By implementing targeted risk management strategies, businesses can reduce risk. This includes the likelihood and impact of cybersecurity incidents. This will help to protect their assets. It also reduces the negative consequences of a security breach.

10 Most Common Smart Home Issues and How to Fix Them

by Tanya Wetson-Catt • 08 May, 2024
Back when you were a kid, living in a “smart home” probably sounded futuristic. Something out of Back to the Future II or The Jetsons. Well, we don’t yet have flying cars, but we do have video telephones as well as smart refrigerators and voice-activated lights. But even the most advanced technology can have analogue problems. Hackers can get past weak passwords. Bad connections can turn advanced into basic pretty quickly. Have you run into any issues with your smart home gadgets? Not to worry! We’ve got your back when it comes to troubleshooting several common smart home issues. Here are some of the most frequent problems. Along with simple steps to get your smart haven back on track. 1. Connectivity Woes Are your smart gadgets refusing to connect to Wi-Fi? The main claim to fame of smart devices is that you can access them wirelessly. An internet connection is also vital to integrate several devices into a smart home hub. If your device is having connection issues, check the basics first. Restart your router and your devices. If that doesn't work, ensure you've positioned your router centrally. This gives you optimal signal strength. Consider a mesh network for large houses. Or invest in a Wi-Fi extender for better coverage. 2. Device Unresponsiveness Now that we have voice-activated devices, we expect them to always answer. It can be frustrating when a device won’t respond to its “wake word.” We might even raise our voice and ask again… only to be ignored. Are you having trouble with your smart devices not responding to commands? A simple power cycle (turning them off and on) can often do the trick. Check for software updates on your devices. As well as the corresponding apps. Updating software can fix bugs and improve performance. 3. Battery Drain Smart devices, especially those battery-powered, can drain quickly. Adjust settings to reduce power consumption. Disable features you don't use. Such as notification lights or constant background updates. Consider replacing batteries with high-quality ones for optimal performance. 4. Incompatibility Issues Not all smart devices are created equal. Just because it says “smart” on the box doesn’t mean it plays well with others. When a new device won’t interact with your network, it can mean money down the drain. Before you buy, check to ensure your devices are compatible with each other. Build your devices around your smart home platform. Review the manufacturer's specifications thoroughly to avoid compatibility headaches. 5. Security Concerns Security is paramount in a smart home. There have been horror stories about hacked baby monitors. These stories can get real very fast. You need to pay attention to securing your devices. Rather than getting caught up in plugging them in as fast as possible. Use strong and unique passwords for all your devices and accounts. Enable two-factor authentication wherever available. Keep your devices and apps updated with the latest security patches. A few other smart device security tips include: Change the default device name on your network. Choose something generic. Put smart devices on a separate “guest” network. This keeps them separated from devices with more sensitive data. Turn off unnecessary sharing features. These are often enabled by default. 6. App Troubles Are you running into sporadic problems? Bugs that crop up intermittently? Sometimes, the problem might lie with the app itself. Check if any app updates are available and install them. Try logging out and logging back in to refresh the connection. If issues persist, uninstall and reinstall the app. 7. Automation Gone Wrong Smart home automations can be convenient, but sometimes they malfunction. Review your automation rules and ensure they're set up correctly. Test them individually to identify any faulty triggers or actions. 8. Limited Range Some smart devices have a limited range. Check the manufacturer’s guide so you know what to expect. Move your devices closer to the hub or router for better communication. Consider using repeaters or extenders if the distance is an issue. 9. Ghost Activity Ever experienced your smart lights turning on or off randomly? This could be due to factors such as: Accidental voice commands Faulty sensors Scheduled automations you forgot about A hacked device Review your automation settings and disable any you don't need. Investigate if your devices are picking up unintended voice commands from other sources. Change passwords and watch out for breaches. 10. Feeling Overwhelmed It’s easy to get overwhelmed when you’re dealing with several smart devices. Don't hesitate to consult your device manuals and online resources. You can also get help from our IT experts for specific troubleshooting steps. These resources can offer more guidance tailored to your situation. Need Help Securing Your Smart Home Office? A smart device should simplify your life, not complicate it. These simple solutions can help you navigate common issues. It’s also important to get a smart home security assessment to keep you, your family and your business protected.

Here Are 5 Data Security Trends to Prepare for in 2024

by Tanya Wetson-Catt • 01 May, 2024
With cyber threats evolving at an alarming pace, staying ahead of the curve is crucial. It’s a must for safeguarding sensitive information. Data security threats are becoming more sophisticated and prevalent. The landscape must change to keep up. In 2024, we can expect exciting developments alongside persistent challenges. Over 70% of business professionals say their data privacy efforts are worth it. And that their business receives “significant” or “very significant” benefits from those efforts. Staying informed about these trends is crucial. This is true whether you’re an individual or a business safeguarding valuable data. Here are some key areas to watch. 1. The Rise of the Machines: AI and Machine Learning in Security Artificial intelligence (AI) and machine learning (ML) are no longer futuristic concepts. They are actively shaping the cybersecurity landscape. This year, we'll likely see a further rise in their application: Enhanced Threat Detection: AI and ML algorithms excel at analysing massive datasets. This enables them to identify patterns and anomalies that might escape human notice. This translates to a quicker detection of and reaction to potential cyber threats. Predictive Analytics: AI can predict potential vulnerabilities and suggest proactive measures. It does this by analysing past cyberattacks and security incidents. Automated Response: AI can go beyond detection and analysis. Professionals can program it to automatically isolate compromised systems as well as block malicious activity and trigger incident response procedures. This saves valuable time and reduces the potential impact of attacks. AI and ML offer significant benefits. But it's important to remember they are tools, not magic solutions. Deploying them effectively requires skilled professionals. Experts who can interpret the data and make informed decisions. 2. Battling the Ever-Evolving Threat: Ransomware Ransomware is malicious software that encrypts data and demands a ransom for decryption. It has been a persistent threat for years. Unfortunately, it's not going anywhere in 2024. Hackers are constantly refining their tactics, targeting individuals and businesses alike. Here's what to expect: More Targeted Attacks: Hackers will likely focus on meticulously selecting high-value targets. Such as critical infrastructure or businesses with sensitive data. They do this to maximize their impact and potential pay-out. Ransomware-as-a-Service (RaaS): This enables those with limited technical expertise to rent ransomware tools. This makes it easier for a wider range of actors to launch attacks. Double Extortion: Besides encrypting data, attackers might steal it beforehand. They then may threaten to leak it publicly if the ransom isn't paid, adding pressure on victims. 3. Shifting Strategies: Earlier Data Governance and Security Action Traditionally, companies have deployed data security measures later in the data lifecycle. For example, after data has been stored or analysed. But a new approach towards earlier action is gaining traction in 2024. This means: Embedding Security Early On: Organisations are no longer waiting until the end. Instead, they will integrate data controls and measures at the start of the data journey. This could involve setting data classification levels as well as putting in place access restrictions. They will also be defining data retention policies early in the process. Cloud-Centric Security: More organisations are moving towards cloud storage and processing. As they do this, security solutions will be closely integrated with cloud platforms. This ensures consistent security throughout the entire data lifecycle. Compliance Focus: Data privacy regulations like GDPR and CCPA are becoming increasingly stringent. As this happens, companies will need to focus on data governance to ensure compliance. 4. Building a Fortress: Zero Trust Security and Multi-Factor Authentication We're in a world where traditional perimeter defences are constantly breached. This is why the "Zero Trust" approach is gaining prominence. This security model assumes that no user or device is inherently trustworthy. Users and programs need access verification for every interaction. Here's how it works: Continuous Verification: Every access request will be rigorously scrutinized. This is regardless of its origin (inside or outside the network). Systems base verification on factors like user identity, device, location, and requested resources. Least Privilege Access: Companies grant users the lowest access level needed to perform their tasks. This minimizes the potential damage if hackers compromise their credentials Multi-Factor Authentication (MFA): MFA adds an important extra layer of security. It requires users to provide extra factors beyond their password. 5. When Things Get Personal: Biometric Data Protection Biometrics include facial recognition, fingerprints, and voice patterns. They are becoming an increasingly popular form of authentication. But this also raises concerns about the potential for misuse and privacy violations: Secure Storage Is Key: Companies need to store and secure biometric data. This is ideally in encrypted form to prevent unauthorised access or breaches. Strict Regulation: Expect governments to install stricter regulations. These will be around the collection, use, and retention of biometric data. Organisations will need to ensure they adhere to evolving standards. They should also focus on transparency and user consent. How to Prepare for Evolving Data Security Trends Feeling a bit overwhelmed? Don't worry, here are some practical steps you and your organisation can take: Stay Informed Invest in Training Review Security Policies Embrace Security Technologies Test Your Systems Schedule a Data Security Assessment Today!
