1.3. Security for the System Administrator

System Administrators, tasked with providing always on computer systems and networks, must be proficient in dealing with attacks on their networks and must also be proactive in thwarting such attacks by the use of planned security drills and audits.
For a successful system administrator, planning for security breaches is a combination of art and science. Security threats, whether they be physical, network or data based, are varying in nature and a successful security system administrator can prepare for outages.
