Abstract:
In recent days possible attacks on the networks has been increased and causing huge financial loss
for the various organization due to lack of proper security standards. Modern networks have
several services and zones like Voice, Data, ISP networks, Access control, surveillance, DMZ
zones and hosting websites etc. Proper planning and access control within each zone are important
to avoid network compromise. This research details on how the network can be security standards
can be implemented using effective controls, in and out of each service zones. The focus of this
research is intended to reduce down time and loss of service in an event of a network compromise
or an external attack such as DoS, Distributed Denial of service attacks, Brute Force attack, Packet
Sniffing and phishing attacks. The results confirm, when the network is structured using effective
controls, in and out of each service zones will increase the security, decrease the down time and
extent of compromise
