Security Issues and Communicate to Staff, Essay Example

There are numerous reasons why a good security system has to be more than that of a simple firewall.  The following explains how ABC Company needs to be concerned about additional preventative measures for its new website.

Malicious logic issues –   This sort of cyber-attack is created by a person who assumes the identity of a legitimate user of the system.  This in turn violates the company security policy by the intent of malicious logic that is aimed at damaging the integrity of the system. This renders traditional access controls as ineffective. Examples of this are Viruses, Trojans and Worms.  The system needs additional protection via anti-virus screening software such as that provided by Norton or MacAfee. (Bishop, M. 2002)

Intrusion Detection –  This represents software that provides a holistic approach towards managing the safety  of the computer network and website.  It encompasses both the firewall and other components, as illustrated in the diagram to the right.  The IDS system  monitors all inbound and outbound traffic on the system and reports any suspicious activity or trends.   This includes those type of patterns that may indicate the someone is either trying to compromise or intrude into the system. (Marchette, D.J. 2001)

Network Perimeter Security –  This essentially relates to the protection of the network by defence strength in depth.  It defines the boundary that exists between that of private and locally managed computer network systems.  This involves defining the perimeter of your computer systems and providing well defined security zones. (Buecker, A. 2008).  The example to the right shows an example of a perimeter network designed by Microsoft Corporation. (Microsoft, 2011)
