A legacy application used for a critical business function relies on software that has reached the end of extended support. Which of the following is the MOST effective control to manage this application?
A.
Increase the frequency of regular system and data backups.
B.
Segment the application within the existing network.
C.
Apply patches for a newer version of the application.
D.
Subscribe to threat intelligence to monitor external attacks.
if confidentiality and integrity is the concern then network segmentation is an effective control.
If Availability is the concern then frequent backups is a effective solution. I am unsure from the question what are they referring to unless there is something missing in the question.
Segmenting the application within the existing network is the MOST effective control to manage the legacy application that relies on software that has reached the end of extended support.
When software reaches the end of its support period, it means that the vendor will no longer provide security patches and updates to address any newly discovered vulnerabilities. This makes the application more susceptible to attacks, and the organization needs to take steps to manage the risk.
