Ensure that each AWS account operates on a least privilege model. Limit access to only the necessary users and services to minimize potential security breaches.
Stay Informed About AWS Updates¶
AWS frequently updates its services and introduces new features. Keep abreast of announcements from AWS to take full advantage of the latest security enhancements.
Develop an Incident Response Plan¶
Prepare for potential security incidents by having a response plan in place. This plan should outline how to react in the event of a security breach, including escalation paths and communication protocols.
