Introduction

Protection against intrusions into the computer system by outsiders is an essential element of
the security policy. But it’s not just intrusion via the Internet that you need to guard against. The
following issues relate to physical safety of the computer equipment on which your information
is stored, the premises in which they are stored, and staff who have physical and electronic
access to systems and information. Some of the most effective advances in security technologies
during the past few decades have been in the area of physical security — i.e., protection by
tangible means.
In this unit we’ll discuss about the physical threats and physical securities.
