Now a days we hear about hacking all on the news social media that hackers hack this website, hackers hack this account using denial of service.
It seems like bad guys are always wrecking. Its true, some of bad guys called 'black hat hackers' doing all kind a damage from cyber attacks to data breaching or worse like stealing personal data.
But did you know there are some good guys mostly called 'white hat hackers' with the same skills. These are called 'Ethical Hackers'.
● Learn How To Be Safe On Internet !!
●Who is Ethical Hacker ?
Ethnical hacker also known as white hat hacker is highly professional security expert. Ethical hackers knows how to find loop holes in systems and exploit the vulnerability of system just like Black hat hacker.
The truth is they use they both use same skills to exploit the system, However Ethical hackers use those skills in lawfull and legitimate manner to help people to secure their system and find exploits the vulnerability before black hat hackers get there and try to break in the system.
An ethicals hacker's role is very similar to a Penetration Tester but with more broder duties. This is the difference in Ethical hackers and Black hat hackers.
The role of an Ethical hacker is very important since the malicious hackers will always be their to exploits the system and trying to find backdoors, loop holes and cracks and the ways to access people's data thay they shouldn't.
● What is Ethical Hacking ?
Apart from testing duties, Ethical hackers have more responsibilities. Main work is to replicate a malicious work of an malicious hacker. Instead of exploiting the vulnerability for dark purpose, seek for solution to countermeasure the system's defense.
Ethical hacker might use all or some of these strategies to penetrate the system.
● Scanning ports and seeking for loopholes :
An Ethical hacker use tools like Nmap and Nessus to do port scanning of own system find open ports.
The vulnerabilities of the open ports can be studied, and remedial measures can be taken.
● Social Engineering :
Ethical hacker engage in social engineering like dumpster through tras bins passwords, sticky notes and other crucial information that can be use to generate cyber attacks.
● Honey Pots and Firewalls :
An Ethical hacker will attempt to evade IPS ( Intrusion Prevention System), IDS (Intrusion Detection System), honeypots and firewalls.
● Sniffing and wireless encryption :
Sniffing networks, bypassing and cracking passwords, Hijacking web servers and web applications, decryption of wireless data.
Detecting the how well the system react to this and other tactics help the security policies.
Ethical hacker attempts the same type of attacks as malicious hacker would try to help the system to straighten their defense.
● Who can be Ethical Hacker ?
As with any profession, passion for the industry is the main key aspect for achieving success.
This combined with good knowledge of networking, programing and pentesting will help the professional to succeed in the hacking field.
For security professional, forensic analyst most importantly people who aspiring in this field CEH is an obvious choice. Many Tech companies have made CEH certification a compulsory qualification for security related post.
CEH training informs its students of Trojans, Backdoors and countermeasure and teaches them a better understanding of firewalls, IDS, wireless hacking and more advace technologies.
