In the past few blog posts, we've been going over the five NIST Framework functions. In the last blog post, we covered the Respond function. In this post, we'll be going over the last Framework function, Recover.
"The Framework Core then identifies underlying key Categories and Subcategories for each Function, and matches them with example Informative References such as existing standards, guidelines, and practices for each Sub category" - NIST CSF
According to NIST, Recover is defined as the need to "develop and implement the appropriate activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cyber security event.
The Recover Function support s timely recovery to normal operations to reduce the impact from a cybersecurity event. Examples of outcomes for this function include : Recovery Planning, Improvements, and Communications."
Recover includes these areas:
- Recovery Planning: Recovery procedures are tested, executed, and maintained so that your program can mitigate the effects of an event sooner rather than later
- Improvement: Recovery planning and processes are improved when events happen and areas for imporvement are identified and solutions put together
- Communication: Coordinate internally and externally for greater organization, thorough planning and execution
The recover function is important not only in the eyes of your business or organization in recovering from an attack, but also in the eyes of your customers or market. Swift recovery handled with grace and tactfullness will allow you to end up in a much stronger position internally and externally than you would otherwise. Prioritizing these focus areas within recover will enure that your organization has a recovery plan that is up to date and matches your organiztion's goals and objectives.
