Network Security
This page offers details of IT network security services,
systems, technology, staffing, news and more. It should provide
useful information for computer administrators, procurement
managers and other information technology professionals.
Quick definition
Network security is the development of computer network infrastructure,
practices and resources to deliver appropriate protection
against unauthorised access or attacks. This differs from
computer security in that, by securing an
entire network, its is possible to prevent intrusions from
ever reach individual computers.
Basics of Internet Security
The starting point is usually user authentication through
a username and password. A firewall can then
define what areas certain users are allowed to access. Its
is then necessary to check network activity in order to identify
and potentially harmful contents, such as worms,
and prevent them from circulating through the network by deleting
them or placing them into a quarantine facility. Such unwanted
contents are often termed malware.
The job of an intrusion prevention system (often called an
IPS) is to identify and block suspiscious
content, as well as unusual traffic that may be flagged for
volume, timing or a range of other reasons. Depending on the
type, size, frequency and severity of the content, it may
be destroyed immediately or kept for further analysis.
All network security systems and techniques must be regularly
updated to keep track with the ever evolving maliscious content
that is developed by potential hackers or intruders.
