| Network administration
measures to ensure data integrity include: maintaining current authorization
levels for all users, documenting system administration procedures,
parameters, and maintenance activities, and creating disaster recovery
plans for breeches, losses and virus attacks.
Data and network security must be maintained so that information
can only be accessed or modified by those authorized to do so. In
any well run business, it is wise to construct a comprehensive security
policy. This consists of plans and procedures which are in a document
that states how a company will protect the company's physical and
information technology assets. A company's security policy may include
an acceptable use policy, a description of how the company plans
to educate its employees about protecting the company's assets,
an explanation of how security measurements will be carried out
and enforced, and a procedure for evaluating the effectiveness of
the policy.

Solution: Firewalls
A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a private network from users
from other networks. Basically, a firewall, working closely with
a router program, examines each network packet to determine whether
to forward it toward its destination. A firewall also includes or
works with a proxy server that makes network requests on behalf
of workstation users. A firewall is often installed in a specially
designated computer separate from the rest of the network so that
no incoming request can get directly at private network resources. |
