Physical Security

Physical Security
Physical security is the basic security that you need to implement. You need to
consider factors such as physical accessibility of people to your system. Home
users may not need to secure their computer physically.In an office environment,
physical security of systems is more critical because they contain data sensitive to
your business. In such an environment, you can take security measures, such as
installing video surveillance and employing security guards.
The physical security you can provide to your system is based on security need and
budget. For example, you will certainly not provide high physical security on a
computer where only games are loaded.A computer with critical and confidential
data will need high physical security.In an office environment,someone can eas-
ily get access to systems by simply walking to a user’s desk and manipulating data.
Common Precautions for Physical Safety
You can take a number of measures to safeguard your PC equipment.Some meth-
ods are inexpensive and can be implemented easily,while others are expensive and
more sophisticated.Here are a few of these measures: Use video surveillance at your workplace.The video cameras should be
hidden and not easily noticeable. Store the backup media at safe places.If possible make copies of the
backup and store them separately. Take care of your computer and other equipment while traveling. Lock the CPU cover to avoid theft of any part,such as motherboard or
hard disk. Lock the equipment in a safe place when you leave. Install security alarms. Employ security personnel to protect your equipment. Restrict access to critical and expensive equipment.Use security mea-
sures,such as fingerprint scanners and voice identifiers. Buy computers and equipment that have built-in security features. Install the servers,such as gateways,that are most prone to attacks on
separate computers.
