Control Assessments

AC-1: Access Control Policy and Procedures

Develops, documents, disseminates, and reviews/updates access control policy and procedures.

Implementation Rating

4/5

Assessment Notes:

Access control policies are documented and reviewed annually. Dissemination occurs through employee training programs. Recent updates include multi-factor authentication requirements.

AC-2: Account Management

Manages information system accounts, including establishing conditions for group and role membership.

Implementation Rating

3/5

Assessment Notes:

Account management processes are established but manual. Automated provisioning is in progress. Role-based access control framework is partially implemented with some legacy accounts remaining.

AC-3: Access Enforcement

Enforces approved authorizations for logical access to information and system resources.

Implementation Rating

2/5

Assessment Notes:

Access enforcement mechanisms exist but are inconsistent across systems. Some applications rely on basic authentication without granular role-based controls. Integration with central identity management is needed.

AC-6: Least Privilege

Employs least privilege principle for access to resources.

Implementation Rating

5/5

Assessment Notes:

Comprehensive least privilege implementation across all systems. Regular privilege audits conducted quarterly. Automated tools monitor and alert on privilege escalations. Employee training emphasizes principle of least privilege.

Strengths

Excellent implementation of least privilege principles (AC-6: 5/5)
Well-established access control policy framework (AC-1: 4/5)
Regular policy reviews and employee training programs

Areas for Improvement

Inconsistent access enforcement across systems (AC-3: 2/5)

Recommendations

Priority 1: Access Enforcement (AC-3)

Implement centralized identity and access management (IAM) solution to ensure consistent enforcement across all systems. Consider integration with existing directory services.

Deploy role-based access control (RBAC) for all applications
Conduct access rights review for all current users
Implement automated access request and approval workflows

Target Completion: Next Quarter

Priority 2: Account Management Automation (AC-2)

Transition from manual account management to automated provisioning and de-provisioning processes to reduce administrative burden and improve security.

Implement automated user lifecycle management
Clean up dormant and legacy accounts
Standardize role definitions across the organization

Target Completion: Within 6 Months

Maintenance: Continue Strong Practices

Maintain existing strong practices in policy management and least privilege implementation through continued training and regular audits.

Continue quarterly privilege audits
Update access control policies annually
Maintain comprehensive employee training programs

Ongoing
