A System Security Plan is a summary of all security practices that protect your data. The SSP can include features in the system such as security measures, training methods, hardware, software, and incident response plans.
This document includes details on restricting access to authorized users and ensuring employees practice safe habits and can respond appropriately in the event of a security breach.
If your IT staff is already familiar with this topic, you can save money by rehashing things internally. Otherwise, it’s better to hire an expert since a poorly written SSP could cost you more than the cost of outside assistance.
