The typical procedures for Internet intruders could include: Information gathering (e.g., use FerretPRO or free tools from https://www.dogpile.com/ to search IRC, USENET, email and file databases for potential information, one previous students in this module has found that one system administrator for a company posted help request for how to turn off the default accounts and password for a new PBX system), target systems scanning (e.g., https://nmrc.org/ https://www.insecure.org/nmap/, https://nwpsw.com/, nbtstat in Win2K or https://www.inetcat.org/software/nbtscan.html, or the tools we discussed in last week's project), back door opening, and log file clean up. As a system administrator, how can you protect your system from these attacks? Can you give a complete hacker story (from technical aspect) including the tools employed by them?
