An important component of traditional security measures is the physical security requirements employed to safeguard valuable computer equipment. This 14-video course examines current physical security practices and how to improve them in the 21 st century. Begin with door and offices locks, fences, and perimeter defenses—solar-powered lights, cameras, motion detectors, and data storage places. Fire suppression systems are important, but consider less obvious benefits of positive airflow systems—preventing dust particles from entering "clean" areas and ensure that air flows out, not in. Laptops must be physically secured at cubicle desks (cable locks); servers must be locked in secure rooms, not under a reception desk. Other tools: privacy screens; so-called "mantraps"—steel shutters walling off outer vestibules; entry control rosters. Be sure to secure mobile devices—tablets, cell phones—against both viruses and unauthorized use by outsiders. Antimalware, antiviral software, multifactor authentication, Smart cards, data loss prevention, and firewalls are also important examples. Emerge from this course better prepared to implement best practices in security in your office. Course helps prepare for CompTIA A+ certification exam 220-1002.
