Q To protect the system
The typical behaviours of Internet intruders include information gathering, target systems scanning, back-door opening and log-file clean-up. A system administrator needs to have the tools, knowledge and experience to protect the system from these procedural attacks. In this Discussion, you will analyse hacker behaviour.
For information on information gathering, you can use any information-gathering service like Metagoofil, FerretPRO or free tools from Dogpile (InfoSpace, 2014) to search IRC, Usenet, email and file databases. For information on target system scanning, you can use a resource like the Nmap.Org (n.d.) site, the Northwest Performance Software (2014) site, nbtstat in Win2K or the tools discussed in last week's project.

Post: Summarise the procedures and tools hackers use for information gathering, target systems scanning, back-door opening and log-file clean-up. Alternatively, give an account of a hacker story from a technical perspective, including the tools employed.

The attack of a hacker is not a simple procedure, rather is a complex procedure that include access to a remote computer, permission of root administrator, utilization of virtual probes, and spying method. In the present context, the focus of the report is based on the procedures and tools that a hacker use for information gathering, scanning of the target system, back door opening, and cleaning of the log file.
Tools such as Whois, Nslookup, and Matagoofil are useful for gathering basic information. The objective of such procedure is collecting information from the target sources using publically available tools (Johnsen & Kristoffersen, 2014).
