All tasks should be a part of this phase. It is important to plan and have proper access controls, anti-virus, up to date patches and software, and backups of the network
Do Phase
An important part of this phase is creating a password policy that would enforce complex passwords. This helps protect your network from unauthorized access. Adding a physical security measure will also help with the security of your network. Locking the physical door to the data center will help protect someone from physically accessing the network. Another important step would be to perform daily backups of the servers. In the event of a system failure or disaster, you can restore most of the data to its most recent state.
Check Phase
It is a good idea to use the MBSA during this phase to identify the baseline of your system by checking the current versions of your software. Using Packet Tracer can help make sure your data is secure. It is always wise to constantly check for new updates to software and anti-virus protection. Monitoring logs can help you test the system or look for vulnerabilities being exploited.
Act Phase
Following guidelines and procedures will help maintain the security and stability of your system.
