Ethical Hacking

An Ethical Hacker must have a Bachelor's degree in Information Technology (B.Sc. IT, Computer Engineering etc.) or an advanced diploma in network security.
A certification from a reputed institute enhances the chances of getting hired by some big names in the IT sector. International Certifications like-
1. Certified Ethical Hacker (EC-Council)
2. Certified Hacking Forensic Investigator (EC-Council)
3. GIAC Certified Penetration Tester (GPEN) by SAN and GIAC
4. Certified Intrusion Analyst (GCIA) can further improve the job prospects.
Besides the aspiring, candidate needs extensive experience in the area of network security and a working knowledge of various operating systems. Areas of expertise include a sound working knowledge of Microsoft and Linux servers, Cisco network switches, virtualization, Citrix and Microsoft Exchange. A working knowledge of the latest penetration software is essential.

As computing becomes all pervasive, the field of computer security is rapidly growing. One of the aspects of this area is the field of penetration testing or what is commonly known as ethical hacking. The first step towards meeting your career objective is to join a company that provides you opportunities to work in the field of information security.
You could do this by joining the traditional IT services companies like TCS, Infosys, Accenture, Wipro etc, who have service offerings around information security; they also need this for their internal requirements.
The other option would be to join companies that specialise in information security - either on the product or service side like VeriSign, McAfee, Citrix, Novell etc. The latter set of companies is very selective about hiring freshers whereas it may be relatively easier to join the former set (however, the issue here could be getting a posting in the information security department as freshers are not given a choice, most of the times).
Next, you should target getting a certification and the most popular one is offered by ECCouncil (www.eccouncil.org) - Certified Ethical Hacker (CEH). Keep in mind that the EC-Council mandates a minimum relevant work experience of 2 years before you can apply for CEH, so the focus for you right now should be to get deep into the various aspects of security at the company you join (campus/off campus doesn't matter) and a precursor to that would be too dirty your hands in core technology so that you know the vulnerabilities associated with designing, building and deploying computer systems.
