Learn how to analyze the vulnerability of your IT system

In an increasingly digital market, information security is a growing concern in companies. The data generated daily is the most precious asset of organizations and, due to data protection laws, it is necessary to ensure compliance with legal requirements so that the company is not penalized. It is essential to know how to analyze the vulnerability of an IT system. In today’s article, we leave you important tips so you can analyze the vulnerability of your system!

But, after all, what is an IT Vulnerability Analysis?

This analysis is part of the information security policy. It is necessary that the company has a strict policy in this area. Vulnerability analysis is an ongoing process of defining, identifying, categorizing, and monitoring security flaws in any context that involves dealing with sensitive business information. This diagnosis is able to qualify the managers’ decision processes in order to guarantee the stability, reliability and availability of the data, systems and general infrastructure of the business.

Steps to do vulnerability analysis

1 – Make a survey of possible threats

Gather information about your technology processes and list key threats that can put your system at risk, such as data loss, natural disasters, outdated software, system failures, and human error.

2 – Create an array for each threat

The risk matrix consists of two components: probability of occurrence of the risk and the impact it will have if the threat occurs. The probability divides into almost certain, alt, average, low, and rare. The impact can be very serious, serious, medium, light and without impact. The greater the risk and the level of impact of the occurrence, the more attention should be given to the situation.

3 – Define a ranking of importance

After putting all the items in the risk matrix, it is necessary to create a degree of importance in order of severity and urgency of resolution. You have to separate what is relevant to the business and what is not so important. At this stage you should also assign responsibilities to the IT team so that they can act immediately if any business-damaging situation occurs.

4 – Define correction measure

This is the most important step in the whole process as this is where you will define your action strategy for each threat. Here you will define preventive and action measures after the problem happens. At this stage you may have to consult an external team in information security, because it will be the team indicated to indicate the most appropriate solutions to your reality.

5 – Continuously assess vulnerabilities

After implementing all the steps and implementing the corrective measures, it is necessary to idealize a plan so that there is a constant evaluation of the vulnerabilities of the IT system. It is important that IT teams always know what is going on in systems so they can act before irrecoverable damage.
