What does the principle of 'least privilege' entail in the context of cloud security?

The principle of 'least privilege' in the context of cloud security is centered around the idea that users should be granted the minimum level of access rights or permissions necessary to perform their job functions effectively. This approach minimizes the attack surface by limiting the number of people who have access to sensitive systems and data and reduces the risk of accidental or intentional misuse of these resources.

By allowing users access only to the resources required for their specific tasks, organizations can enhance their security posture. If a user's credentials are compromised, the potential damage is contained to the limited set of resources they are authorized to access, rather than giving a malicious actor broader access to the entire system or sensitive information.

This principle is critical in cloud environments where multi-user access is common, as it helps enforce a security strategy that mitigates risks associated with privilege escalation, insider threats, and data breaches. This structured access control also assists in compliance with regulatory frameworks that require strict access management policies.
