This document discusses network security over Ethernet. It provides information on various Ethernet technology standards such as 802.3, 802.11, and 802.16 and discusses their physical/logical characteristics and whether they use guided or unguided media. It also shows the security levels of various operating systems such as Windows, Linux, and their distributions. Furthermore, it discusses what information an intruder seeks outside an operating system, how attacks are performed through techniques like port scanning and covering tracks using rootkits.

- 5. 5 WHAT ? • What an Intruder Seek? • What an intruder do with that information? • What should be protected? • What resources are required to protect?
- 6. What Information are required to Attack a user? The security level for a user is become incredibly low. An attack can be made by having these information: 1) An IP Address 2) Operating System Vulnerability 3) Vulnerability Exploit and 4) A connection Oriented Session
- 7. 7 How Attacks are Performed • Port Scanning • Network Scanning • Information Gathering • Vulnerabilities Assessment • Trace Route. • Steganography
- 8. 8 Covering Tracks • Root kits • System log Removal • Databases Injection
