Limiting access to critical information based on the principles of need-to-know and least privilege is essential for maintaining strong information security. These principles ensure that individuals or systems only have access to the data and admin privileges necessary for their roles, reducing the risk of unauthorized access or misuse.
By applying the principle of least privilege, you minimize the impact of a compromised account or insider threat, helping to safeguard data confidentiality and integrity. This practice is a key requirement in major security and compliance frameworks, such as NIST, ISO 27001, HIPAA, and GDPR, emphasizing its critical role in protecting sensitive information.
