1. NETWORK INTRUSION SECURITY BREACHES, THAT MAKE NETWORKS VULNERABLE TO UNAUTHORIZED ATTACKS

2. INTRODUCTION The world of computers has changed dramatically in the past thirty years. Though INTERNET is good for the spread of information, it has also led to the proliferation of malicious information. This paper, discusses the various threats applicable to Internet hosts, running server software or working on a multi-user OS like UNIX.

3. SECURITY BREACHES Access control management : Guessing, Tools like Cracker Jack, Protocol analyses programs, Trojan Horses. Communication Protocols : IP address Spoofing, Internet Routing attacks. Internet Applications : Risks involved in Telnet, DNS services, SMTP services. Information services : Risks in WWW servers(URL spoofing, CGI attacks)

4. CONCLUSION SECURITY TECHNOLOGIES: Firewalls, Intrusion Detection system(IDS). Information security isn’t necessarily easy - But it is an involuntary element in doing business. Threats change, vulnerabilities change, business requirements change, and available counter measures change. Hence the security policy must be periodically and routinely re-evaluated.
