Network Security

Networks and the data held on them should be kept secure. There are many different ways of improving network security, including the use of:

	logical access control, i.e. use of user identity (ID) codes, password systems and access rights
	control of physical access, for example passcards, locks on workstations
	virus checking software
	backup and recovery procedures
	archiving.

You will need to know how each of these security measures is used, and how they can be used in combination.

You must also understand the responsibilities of a network manager in maintaining network security. You must learn how the network manager attempts to improves network security by:

	user group maintenance (creating users, allocating passwords, setting permissions, allocating file space)
	installing software
	monitoring and testing the network (disk space, deleting files, print queue, user activity)
	connecting workstations, cables, peripherals
	virus checking.
