The network security always remains attraction for the IT security professionals due to the availability of various solutions for the single problem such as opting single layered security approached e. g. , Software Based Firewall or Either select for High Range Firewalls or go for mixed solution which include the deployment of firewall including the NIDPS and Optional Monitoring Tools. However it is always tough for them to select which solution is the best one due to managerial as well as technical issues which suits to their organization's problem in current scenario [1]. In this paper we are discussing about the network security issues in the context of firewalls, how to opt an appropriate solution in view of present problem if any. The administrators options varies from the theoretical approach as they do not follow the security standards and their policies as mentioned in security books however in the organization instead of that they just tuned up most demanding protocols and handle the most immediate problem in context of security.
