Understanding how threat modeling works is an important part of your company security program. By identifying the areas of vulnerability and finding out how to prevent criminal activity, you can ensure that your company assets and data remain secure. A good security plan will help you to determine the company assets that are likely to be targeted and who may be after your data and how they may gain access to your data.
Threat modeling is different from testing applications in that it evaluates and understands the areas that need most attention from a security perspective. The process does not have to be complex and it can be as simple or complicated as you want it to be. Simple threat models can be used effectively to train team members and secure participation from everyone in the organization. Following are steps to ensure successful threat modeling.
Find out how the criminals would do it
The best way to find out how criminals would get into your system is by asking the experts themselves how they would do it if they were trying to steal information. Different people from the engineers and developers to the help desk personnel can offer crucial information about how their processes can be circumvented. Ask the individuals playing the role of “criminal” to tell you how they would break into the systems that you use. These modeling sessions can offer highlights about gaps in your security plan.
Prioritize your security needs
After receiving feedback from your “criminals”, you are likely to be faced with numerous scenarios about security breaches. To avoid getting too overwhelmed, you should prioritize by analyzing the scenarios that are most likely to occur. Find out the areas that can cause the most damage to the company and where you need most security. The loss of crucial data or intellectual property theft will affect the company in a much more serious way than having the company website shut down.
Come up with countermeasures
When you identify potential threat factors, you will understand your position and you can come up with countermeasures. You need to come up with both active and passive measures that will help to mitigate the risk at every stage. Some of the countermeasures that you need will include educating staff, ensuring incident response and using anti-phishing and other technologies. You need to have a comprehensive plan that will offer protection at different stages. Investing in effective proactive maintenance strategies is a good idea.
Implementing and testing the solution
When you know exactly what you need, you have the right foundation for implementing the solutions. You can plug the security gaps yourself if you have the budget and expertise but the best idea is to get outside help. Using an external firm to test and implement the solutions will ensure you solve your problems effectively. Having the firm protect your vital data and provide data recovery services will mean that you do not have to worry about theft or loss from other causes. A successful threat model will help you to know where you should concentrate your security efforts.
Knowing where you stand will help you to implement the best security measures. Threat modeling can also help you to know if you need to change some of your IT vendors.
