"2. The Biggest Security Risks are Internal - As any good security expert will tell you, most security issues arise from inside a corporate network not from the outside. Most port scans, virus attacks, hacks, password stealing, and stolen data occurs from within your own ranks. Linux Administrators have the advantage of using a Unix Operating System that is inherently secure by virtue of the limited ability of users to damage the system.
Local users still pose the biggest security threats to a system through the download and use of rootkits, port scanners, and password crack programs."
