    Study Notes

    Reducing Malevolent Activity

    • Principle of separation of duties should be employed to reduce the risk of malevolent activity without collusion.

    Account Usage

    • Non-privileged accounts or roles should be used for performing routine, daily tasks.

    Logon Attempts

    • Limiting unsuccessful logon attempts is done to prevent brute-force attacks and to reduce the risk of unauthorized access.

    Protecting CUI

    • Encrypting CUI (Controlled Unclassified Information) on mobile devices is done to protect the confidentiality of sensitive information.

    Cryptographic Mechanisms

    • Cryptographic mechanisms such as SSL/TLS and IPSec should be employed to protect the confidentiality of remote access sessions.

    Access Control Definition

    • NISTIR 7298 defines access control as the process of granting or denying access to a resource based on a user's identity, authentication, and authorization.

    Access Control Regulation

    • According to RFC 4949, access control regulates the access of subjects to objects, ensuring that only authorized entities have access to the resources they need.

    Basic Security Requirements

    • One of the basic security requirements for access control according to SP 800-171 is to limit access to authorized personnel, ensuring that only those with a legitimate need have access to sensitive resources.

    Access Control Focus

    • The main focus of access control according to NISTIR 7298 is to ensure that access to resources is restricted to authorized individuals, entities, or systems.

    Authorized Entities

    • According to RFC 4949, authorized entities are individuals, systems, or processes that have been granted access to system resources based on their identity, authentication, and authorization.
