With the growing number of cyber attacks, system invasions, data theft, malware attacks such as Ransomware among others, vulnerability management to prevent invasions and ensure information security has become an indispensable task for IT professionals and organizations in general. In addition to implementing security mechanisms to protect oneself, it is necessary to know the vulnerabilities and deal with them. The issue of vulnerability management is so serious that even in the phase of a penetration test or cyber attack, the phase that precedes the invasion, is the discovery of vulnerabilities, i.e. when an attacker wants to attack a system, he will need to know the vulnerabilities and after knowing them, exploit them. Therefore, in this course you will have the opportunity to learn how to find the vulnerabilities in systems, find solutions, and elaborate a mitigation plan for them and implement countermeasures with the best practices guide according to the Center for Internet Security (CIS Control Set), an entity that works to support organizations to implement best practices for asset management and data backup. It is important to know how vulnerability scanners work for better positioning when it comes to decision making after analysis. After completing this course, you will be able to implement and manage OpenVas as well as assign tickets to the different people responsible for each department where vulnerabilities are detected as well as to IT professionals.
