Protecting today’s systems and networks requires a broad understanding of attack strategies and a deep understanding of hacker tactics, tools, and motivations . The increasing use of social engineering attack methodologies demands that each tester be aware of the organization and the habits of its IT users (staff).
Sometimes internal personnel are chosen, responsible within the company for testing infrastructure vulnerabilities, but it is also complicated for smaller SMEs. For this reason, they may choose to resort to cybersecurity companies that offer an external consulting service but that allow them to be prepared for attacks by hackers with bad intentions. In some cases these consultants may turn to ethical hackers who can make sure to spot any security weaknesses.
Ethical hacking is defined through what the professionals dedicated to it do, that is, ethical hackers, who do not resort to these practices for criminal purposes, traditionally associated with these actions. These people are hired to hack into a system and identify and fix potential vulnerabilities, effectively preventing exploitation by malicious hackers. They are experts who specialize in the penetration testing of computer systems and software in order to assess, harden and improve security. We can say that they are in charge of implementing an ethical hack to test the security of the system.
This type of hacker or hacker type is often referred to as a ‘white hat’ hacker , in order to differentiate them from criminal hackers, who are known as ‘black hat’ hackers.
One of the most powerful weapons in the fight against cybercriminals has been hackers. Professionals with a deep understanding of how to penetrate the security of an online infrastructure commonly implement measures and firewalls to find vulnerabilities that those on the other side of the moral hacking spectrum would seek to exploit.
