As the threat landscape continues to evolve, businesses must take proactive steps to protect their sensitive data and assets from cybercriminals.
With digital sophistication becoming the norm in today’s offices, hackers can breach systems through various entry points, including computers, smartphones, cloud applications, and network infrastructure. To combat these intrusions, organisations can employ threat modelling — a process in cybersecurity that involves identifying potential threats and vulnerabilities to their assets and systems.
Threat modelling plays a crucial role in helping businesses prioritise their risk management and mitigation strategies, with the goal of mitigating the risk of falling victim to a costly cyber incident.
Steps to Conduct a Threat Model
#1 Identify Assets That Need Protection
Begins by identifying the assets that need protection, including sensitive data, intellectual property, financial information, and company email accounts that are increasingly targeted through business email compromise (BEC) attacks.
#2 Identify Potential Threats
Next, potential threats need to be identified, which can range from cyber-attacks like phishing, ransomware, and malware to physical breaches or insider threats. Threats are not always malicious, as human error can also be a large factor in data breaches. Mistake-related threats such as weak passwords, unclear cloud use policies, lack of employee training, and poor BYOD (Bring Your Own Device) policies should also be considered.
#3 Assess Likelihood and Impact
Once potential threats are identified, assessing the likelihood and impact of each of these threats is crucial. This involves understanding how likely each threat is to occur and the potential impact on operations, reputation, and financial stability. It is best to get a thorough assessment from a 3rd party service provider to cover all grounds.
#4 Prioritise Risk Management Strategies
With the likelihood and impact of threats evaluated, businesses can prioritise their risk management strategies. This prioritisation should be based on the potential impact on cybersecurity, considering factors like access controls, firewalls, intrusion detection systems, employee training and awareness programs, and endpoint device management. The cost-effectiveness and alignment with business goals should also be considered when implementing these strategies.
#5 Continuously Review and Update the Threat Model
It is important to note that threat modelling is an ongoing process. Cyber threats are constantly evolving, necessitating regular reviews and updates to the threat models. By continuously assessing and updating their models, businesses can ensure the effectiveness of their security measures and alignment with their objectives.
Benefits of Threat Modelling for Businesses
Enhanced Understanding of Threats and Vulnerabilities
Through threat modelling, businesses gain valuable insights into specific threats and uncover vulnerabilities that could potentially impact their assets. It enables them to identify gaps in their security measures and develop effective risk management strategies.
Proactive Defence Against Emerging Threats
Ongoing threat modelling helps companies stay ahead of rapidly evolving cyber threats. With the advent of artificial intelligence (AI), new types of cyber threats emerge daily. By continuously assessing and updating their threat models, businesses can avoid complacency and proactively protect themselves against new attacks.
Cost-Effective Risk Management
Addressing risk management based on the likelihood and impact of threats allows businesses to optimise their security investments. This approach ensures that resources are allocated efficiently and effectively, reducing unnecessary costs while maximising the protection of assets.
Alignment with Business Objectives
Threat modelling aligns security measures with the overall objectives of the business. By considering the potential impact of security measures on day-to-day operations, organisations can minimise disruptions and ensure smooth coordination between security, goals, and operations.
Reduced Risk of Cyber Incidents
By implementing targeted risk management strategies informed by threat modelling, businesses significantly reduce their overall risk profile. This includes lowering the likelihood and impact of cybersecurity incidents, safeguarding their assets, and minimising the detrimental consequences of a security breach.
