The layered security scheme might include antivirus software 's , encryption standards , firewalls , router , intrusion detection system and virtual private networks . System study is very important before installing any network security tools . System study involves gathering information about type of application , network model , traffic flow analysis , and internet and intranet communications

Based on the system study , the network security tools

can be chosen for the system or network . The effective network security tool can be installed for system that communicates less in the network . For example home computer connected to the internet . The effective network security tool cannot be used in the system that involves lot of business transaction . The cost of implementation of effective security tools would be less when compared with installing many security tools . The risk involved is very much higher in implementing the effective network security tools . The cost of risk is very much higher . Implementing many tools for network security involves higher costs for implementation only and the risk is lesser

All the network security tools focus only on controlling the perimeter of boundaries in the networks . Complete risk elimination is not possible by implementing either solution . Nessus , wire shark , kismet and topdump are some of the network security tools used for providing effective solutions for the enterprise and individual users . Besides implementing the network...
