How to Use Threat Modelling to Reduce Your Cybersecurity Risk

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 including computers, smartphones, cloud applications, and network infrastructure.

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

One approach that can help organisations fight these intrusions is threat modelling. This is a process used in cybersecurity which involves identifying potential threats and vulnerabilities to an organisation’s assets and systems.

Threat modelling helps businesses prioritise 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 which capitalises 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 third party IT service provider. If you’re doing your assessment with only internal input, you’re bound to miss something.

Prioritise Risk Management Strategies

Base these strategies on the likelihood and impact of each potential threat. Most businesses can’t tackle everything at once due to time and cost constraints. It’s therefore 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 as cyber threats are constantly evolving. Businesses must continuously review and update their threat models to 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 and 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 and can optimise 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 to 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 and also reduces the negative consequences of a security breach.
