Rapid Freight Converged Network Security Case Study

Rapid Freight Converged Network Security - Case Study Example Accidentally, internal threats occur when people use their portable devices outside the network then plug them back in importing viruses and other malware. Some members of staff might be malicious and try to access unauthorized segments (Paul, 2011). External threats are easily kept at bay through the implementation of firewalls. A firewall allows a flow of data from known sources to the web server or specified destination while rejecting unknown traffic. If the firewall is compromised, it severs the connecting of the system to the internet host. Notwithstanding, firewalls are not perfect and should not be used solely (Stewart, 2010). Unified Access Control and Network Access Control ensure that device users are authorized to use the network. Account management system registers network users and signals any illegal activity. Coupled with Personalization, the intervention will keep the network safe from internal threats of any nature (Gregory, CISA, & CISSP, 2007). Implementing session management features such as Virtual Private Networks (VPNs) will overcome challenges posed by the use of VoIP phones, Video conferencing and PDAs. IPSec VPN scrambles traffic from the phone and safely connects to the corporate network without fear of infiltration. Softphone users will require authentication into the Converged network. Secure Socket Layer VPN (SSL VPN) ensures that users are logging in from healthy computers when accessing the network remotely. Intrusion Detection and Prevention software (IDS and IPS) will further enhance overall security by scanning entire network to identify and report signatures or suspicious traffic arrays (Gregory et al,  2007).
