You need protection from hacker shenanigans; you have to become as savvy as the guys trying to attack your systems. A true security assessment professional possesses the skills, mindset, and tools of a hacker but is also trustworthy. He or she performs the hacks as security tests against systems based on how hackers might work.
Ethical hacking — which encompasses formal and methodical penetration testing, white hat hacking, and vulnerability testing — involves the same tools, tricks, and techniques that criminal hackers use, but with one major difference: Ethical hacking is performed with the target’s permission in a professional setting. The intent of ethical hacking is to discover vulnerabilities from a malicious attacker’s viewpoint to better secure systems. Ethical hacking is part of an overall information risk management program that allows for ongoing security improvements. Ethical hacking can also ensure that vendors’ claims about the security of their products are legitimate.
