A financial institution is set to initiate an update to its transaction processing platform. Ahead of this update, the security department must ascertain that the platform's security integrity remains intact. Which initial step should the security department take to ensure that the platform's upgrade will not weaken its current defense mechanisms?
Broadcasting the timetable for the update to all involved parties.
Monitoring user interactions with a beta version of the updated platform.
Combing through the documentation of the system's current deployment.
Evaluating the potential effects of the update on the system's defenses.
The pivotal initial step in preparing for a platform update from a security standpoint is to analyze the possible effects the upgrade could have on existing security measures. This analysis aids in identifying any new threats that the upgrade might introduce and verifies the effectiveness of current security controls following the platform changes. While inspecting existing system documentation is important for context, it does not address the prospective impact of new changes. Notifying stakeholders is more about change management communication than security assurance. Observing how users interact with a beta release can reveal usability problems, but it is secondary to evaluating and maintaining security standards.
