Study Notes

Access Control

The main purpose of access control is to regulate the use of system resources.

Access Control Security Requirements

One basic security requirement for access control is to control the flow of Controlled Unclassified Information (CUI).

Principle of Least Privilege

The principle of least privilege is a security principle that involves granting users or roles only the privileges needed to perform specific tasks.

Non-Privileged Accounts

Using non-privileged accounts or roles when accessing non-security functions helps prevent exploitation of elevated privileges by attackers.

Limiting Unsuccessful Logon Attempts

Limiting unsuccessful logon attempts helps prevent brute-force attacks.

Cryptographic Mechanisms

Employing cryptographic mechanisms is necessary to protect the confidentiality of remote access sessions.

Encrypting Controlled Unclassified Information

Encrypting controlled unclassified information (CUI) on mobile devices is important because it helps protect sensitive information from unauthorized access or theft.
