Assignment 2: Business Impact Analysis
Security threats in a network environment are far much detrimental and can always paralyze operations in organisations and business environments. Security threats on the remote machines can always be averted easily and their impacts are not as serious compared to threats on the central computer system (Kaufman et al, 2002).The central computer system is a valuable resource that must be secured to ensure continued operation in the organisation. Securing a central computer network is the key to ensuring network security in any institution (Kaeo, 1999).
To secure the network and ensure a degree of protection from external intrusion, the first step is to ensure it is a private network and each host in the different remote locations is part of the private network; this minimizes the intrusion from public networks. Through the use of firewalls in the central computer network enforces authentication of all users in the network thus minimizing internal and external unauthorised access (Stallings, 2007).
To secure against attacks from the internet and the external networks the use of a strong antivirus software and internet security software in all the workstations, hosts and servers is important. In addition to this it is important to have a network security policy that will clearly stipulate the use of the Library property and also provide the guidelines on using personal resources in the library network. Since the network is private a white list of all authorised wireless networks should be maintained to avoid unauthorised access from external wireless networks. It is also important to ensure that all hardware and software is in secure zones and environments to avoid physical damage (Stallings, 2007).
These are basic steps towards securing the central database from attacks such as denial of service that is mainly caused by unauthorised access. The strategy is simple and less costly thus cannot cause strain on the budget.
