How to Start a Threat Assessment

Starting a threat assessment can be a complex process, as it involves numerous steps and precautions. If a threat assessment plan is incomplete or overlooks potential threats, it puts everyone involved at risk. In this newsletter, I'm going to share my thoughts on starting a threat assessment in an organized way.
Prioritize Which Assets Need Protection
The process of starting a threat assessment begins with identifying the assets you want to protect. You need an comprehensive understanding of the technologies, applications, systems, databases, and most importantly the data your organization wants to protect. It is likely your team already has an inventory of technology to start from. With this information you can evaluate different assets based on the value of the data they store or process and prioritize the assets most valuable to the organization.
Identify Potential Threats
Next, you will want to identify potential threats. It’s important to research threats specific to your business environment and to look holistically in order to catch any anomalies or changes in behavior or conditions. Start by understanding the current situation, and evaluating the risks associated with different activities and situations. For example, if the business has recently changed product lines or services, that could create new risks. If the business works in the banking sector, then breaches of information security need to be considered. Additionally, consider economic, social and political changes that could lead to new threats.
It is also important to consider the potential for natural disasters, such as floods, hurricanes, or earthquakes, that could disrupt operations. Additionally, consider the potential for cyber-attack, which can be difficult to detect and can cause significant damage. Finally, consider the potential for human error, such as an employee accidentally deleting important data or making a mistake that could lead to a security breach.
Also, consider your competitors. Research the volume of companies in your business space that have had security breaches in the last few years, what data the attacker was targeting, and what methods were used to breach the systems. Chances are if your competitors are being targeted, those attackers pose a threat to you as well.
Analyze The Risk
Once the potential threats have been identified, you can start analyzing the risk associated with those threats. It’s important to assess each threat objectively and consider the likelihood of an attack occurring, the probability that it would be successful, and the level of risk it causes. A risk matrix can be helpful to visualize this assessment. Additionally, estimating the financial impact of each threat is also key to determining which threats require immediate attention.
It is also important to consider the potential impact of a threat on the organization’s reputation. If a threat is successful, it could lead to negative press and a decrease in customer trust. This could have a long-term impact on the organization’s bottom line. Therefore, it is important to consider the potential reputational damage when assessing the risk of a threat.
Develop An Action Plan
Once the risk of each threat has been assessed, it’s time to develop an action plan. This plan should include how best to respond to each threat, how often and for how long preventive measures should be deployed, as well as developing specific protocols for unusual scenarios. Developing this plan can be difficult as there may be too many potential scenarios to consider. In this case, you may want to consider an external consultant who is experienced in this area of work.
The action plan should also include a timeline for implementation, as well as a budget for any resources needed. It is important to ensure that the plan is realistic and achievable, and that it is regularly reviewed and updated to reflect any changes in the risk environment. Finally, it is essential to ensure that all stakeholders are aware of the plan and their roles in its implementation.
Establish Guidelines And Protocols
The next step is to put the action plan into practice – this includes establishing guidelines and protocols for the organization. It is important to ensure the guidelines are comprehensive enough to cover all eventualities, while also being simple and easy-to-understand so that everyone involved can adhere to them. Clear communication is the key here.
You will also want to ensure that the guidelines are regularly reviewed and updated to reflect any changes in your organization or the business environment. This will help to ensure the guidelines remain relevant and effective. Additionally, it is important to provide training and support to those responsible for implementing the guidelines, so that they are able to do so effectively.

Implement The Threat Assessment Plan
After the guidelines and protocols have been established, it’s then time to implement the threat assessment plan. Consider what preventive measures need to be taken in order to reduce the risk of attacks and strengthen your organization’s cybersecurity. This may include implementing advanced technologies, such as artificial intelligence (AI) for data analysis and machine learning for pattern-based detection. Additionally, consider updating employee policies regularly and ensuring everyone has sufficient training related to security measures.
You will also want to ensure the organization has a comprehensive incident response plan in place. This plan should include steps for responding to a security incident, such as identifying the source of the attack, containing the damage, and restoring systems to their original state. Additionally, the plan should include procedures for reporting the incident to the appropriate authorities and communicating with stakeholders.
Monitor And Evaluate The Plan
Once the threat assessment plan is in place, it needs to be regularly monitored and evaluated in order to ensure its effectiveness. Monitoring can be done manually or by leveraging automated systems such as log data analysis. Additionally, analyzing employee behavior can help identify irregularities. Evaluating the results of monitoring on a regular basis can help determine which measures are working and which need to be updated or replaced.
It is important to ensure that the threat assessment plan is regularly reviewed and updated to reflect any changes in the business environment or your organization. Additionally, it is important to ensure that the plan is communicated to all relevant stakeholders, including employees, customers, and partners. This will help ensure that everyone is aware of the plan and can take the necessary steps to protect the organization.
Revise The Plan As Needed
The final step is revising the threat assessment plan as needed in order to keep up with any changes in the business environment or technological advances. It's important to continually review assessments and update protocols to make sure they are up-to-date and effective at mitigating threats. This involves reevaluating risks often, determining whether new strategies are necessary, and making sure everyone involved is properly trained.
It is also important to ensure that the threat assessment plan is regularly tested and evaluated. This can be done by running simulations and drills to ensure that the plan is effective and that all personnel are familiar with the procedures. Additionally, it is important to review the plan periodically to ensure that it is still relevant and up-to-date with the latest threats and technologies.
