Threat Model
The cyber security threat model is a structured approach used to identify, evaluate and address potential security risks to an organization's digital assets. This model is used to ensure that security measures are designed, implemented, and maintained in a way that effectively addresses the organization's unique security needs.
The Guardinia Approach to Cyber Security Threat Modeling
Assets: The first step in the threat model is to identify digital assets that the organization wants to protect, including data, hardware, software, and networks. These assets are evaluated based on their value to the organization and their potential impact if they are compromised.
Threats: Once assets are identified, the next step is to identify potential threats to those assets. This includes both internal and external threats, such as malicious insiders, cyber criminals, and state-sponsored attackers. Threats can also come from unintentional sources, such as human error or natural disasters.
Vulnerabilities: The next step is to identify vulnerabilities in the organization's systems and processes. This includes vulnerabilities in software, hardware, and network configurations, as well as weaknesses in organizational policies and procedures.
Risk Assessment: Once the assets, threats, and vulnerabilities are identified, we assess the level of risk associated with each potential threat. This involves evaluating the likelihood of a threat occurring and the potential impact it would have
Countermeasures: The final step in the threat model is to implement countermeasures to reduce the risk of an attack. This includes implementing security controls, such as access controls, encryption, and monitoring, as well as educating employees on security best practices.
The cyber security threat model is an ongoing process, and organizations must continually evaluate and adjust their security measures based on changes to their digital assets, threats, and vulnerabilities. By following this structured approach, organizations can effectively mitigate security risks and protect their valuable digital assets.
