Network Operating Systems and Security BEng - Assignment ExampleIn the context of engagement credentials definition, it consists of concerns related to network communication privacy, confidentiality of data over the network, accessing unauthorized categorise data, access to prohibited network domains and utilizing Internet for concealed communication (Network Security. 2007). The security predictions that were published in an term for the year 2010 incorporates new advanced threats named as advanced persistent threats (APT), Cyber war escalates, VoIP attacks, Perimeter shrinks and harden, social networking sites, malw are, DLP for happy property protection and malware as a service (MaaS) (Watchguard Unveils Top 10 Security Predictions for 2011. 2011).

The document will provide a consistent framework to secure the integrity of the network along with eliminating risk abided by security threats and vulnerabilities. 2 Risk Assessment Risk assessment is a process to evaluate risks associated with threats and vulnerabilities to the network. Three factors will be considered in this scenario i.e. Assets, Threats and Security Priority Identification. 2.1 Assets The identification of education assets is vital before conducting risk assessment.
