Why Security?

• Increasing use of Complex computer infrastructure.• Increasing use of Network elements & applications.• Decreasing level of skill set.

Why Security?

• Any Security breach in company will affect its asset &goodwill.

•Any Security breach in government can affect itsoperations & reputation.

• Vulnerability notes can be search on internet via Number, CVE.

Vulnerability Research References

• Common Vulnerability database is available at

http://cve.mitre.org/

•National Vulnerability Database is available at

http://web.nvd.nist.gov/http://web.nvd.nist.gov/

• US – CERT also publishes CVD on http://www.us-cert.gov

1. Contains Alerts which can be helpful to administrator.2. It doesn’t contain solutions.


• Indian CERT also published advisory notes, incident notes & defacement statistics.


• Secunia also published Vulnerability Notes,Advisories.


•Zone –h published deface images of web attacks.


•Zone –h maintains archive of deface webpages which can be sorted out by attacker name & country.


•Milw0rm Maintains latest vulneability notes,white papers,videos.


• HackerWatch lets you report and share information that helpsidentify, combat, and prevent the spread of Internet threats andunwanted network traffic.

Conclusion

• Security is important because prevention is better than cure.

• Community of Hackers.

• Security Involves five phases.

• Ethical Hacking involves Conducting Security Audits, Vulnerability • Ethical Hacking involves Conducting Security Audits, Vulnerability Assessment & Penetration testing

• Vulnerability Research is process of discovering different vulnerabilities in technology & applications.
