ACCESS CONTROL POLICY
Halvorsen Precision Machining LLC
Policy owner: Dana Ruiz, Operations Manager
Approved by: Mark Halvorsen, President
Effective date: 2026-11-02
Review: every 12 months
Requirements: NIST SP 800-171 Rev 2, family 3.1 Access control (22 requirements, CMMC AC.L2-3.1.1 to AC.L2-3.1.22)
1. Purpose
Who may use the systems that hold CUI, what each person may do there, and how CUI is kept on the paths we approved.
2. Scope
This policy applies to everyone who works for or on behalf of Halvorsen Precision Machining LLC and to the CUI enclave (cloud email and file storage, and the four CAD/CAM workstations), as described in the system security plan.
3. Who gets access
3.1 Only people Halvorsen Precision Machining LLC has authorized, the service accounts and processes they run, and company-issued or approved devices may use the CUI enclave (cloud email and file storage, and the four CAD/CAM workstations). The Operations Manager keeps the list of authorized users and devices and reviews it every 12 months. [AC.L2-3.1.1]
3.2 Each person gets only the access and functions their job needs: the shop floor reads the drawings and travelers it works from, only the people who quote and program jobs add or change CUI files, and only named administrators change security settings. [AC.L2-3.1.2, AC.L2-3.1.5]
3.3 No one person both makes and approves a security change: changes made by Northgate IT are approved by the Operations Manager, and the two duties are listed in the system security plan. [AC.L2-3.1.4]
3.4 Administrators use a separate standard account for email, browsing and everyday work, and sign in as administrator only to administer. [AC.L2-3.1.6]
3.5 Standard users cannot run privileged functions such as installing software, creating accounts or changing security settings, and every use of a privileged function is written to the audit log. [AC.L2-3.1.7]
4. Signing in and leaving a session
4.1 An account locks after 5 failed sign-in attempts in a row and stays locked until Northgate IT unlocks it or the lockout period ends. [AC.L2-3.1.8]
4.2 Every system in scope shows a notice before sign-in: the system belongs to the company, holds controlled unclassified information, and use is monitored. [AC.L2-3.1.9]
4.3 Screens lock after 15 minutes without input, and the lock screen hides what was showing. [AC.L2-3.1.10]
4.4 Remote and web sessions end automatically after 8 hours, and sessions on shared shop-floor computers end at the end of each shift. [AC.L2-3.1.11]
5. Remote access
5.1 Remote access to the CUI enclave (cloud email and file storage, and the four CAD/CAM workstations) goes only through the company VPN or the cloud service's own sign-in, both of which encrypt the session. Northgate IT monitors and logs remote sessions. [AC.L2-3.1.12, AC.L2-3.1.13, AC.L2-3.1.14]
5.2 Privileged commands and security information are used remotely only by the administrators the Operations Manager has named in writing. [AC.L2-3.1.15]
6. Wireless and mobile devices
6.1 Northgate IT approves every wireless access point before it is connected. Wireless networks that reach CUI systems use encryption and individual sign-in; the guest network is kept apart. [AC.L2-3.1.16, AC.L2-3.1.17]
6.2 Phones and tablets may reach CUI only after Northgate IT enrols them in device management, and CUI on them is encrypted. [AC.L2-3.1.18, AC.L2-3.1.19]
7. CUI paths, outside systems and public posting
7.1 CUI moves only along the paths in the system security plan, between the CUI enclave (cloud email and file storage, and the four CAD/CAM workstations) and the people authorized for it. It is never forwarded to personal email, consumer file sharing or chat apps. [AC.L2-3.1.3]
7.2 Personal computers, home networks and customers' or suppliers' systems are external systems. CUI is not processed on them unless the Operations Manager approves the connection in writing and it is listed in the system security plan. [AC.L2-3.1.20]
7.3 Portable storage holding CUI is not used on external systems. [AC.L2-3.1.21]
7.4 Only the people the Operations Manager names may post to the website, social media or customer portals, and they check first that nothing posted is CUI. [AC.L2-3.1.22]
8. Evidence we keep
- The list of active accounts with the person behind each, and records of recent leavers and transfers
- Configuration settings for lockout, session lock, remote access and wireless
- The approved list of external systems and mobile devices
- Audit log entries showing privileged functions being recorded
9. Exceptions and review
Any exception is approved in writing by the approving official, recorded with its reason and end date, and reflected in the system security plan. This policy is reviewed on the cycle above and whenever our systems, contracts or the rules change.

3.2 Everyone uses their own account. Shared logins are not allowed, so every logged action traces to one person. [AU.L2-3.3.2]
3.3 All systems take their time from one authoritative time source, so timestamps line up across logs. [AU.L2-3.3.7]
4. Review and alerts
4.1 The Operations Manager and Northgate IT review the list of logged events every 12 months and after any incident, and update it. [AU.L2-3.3.3]
4.2 Northgate IT is alerted when logging stops, fails or runs out of storage. [AU.L2-3.3.4]
4.3 Logs from different systems are reviewed together at least weekly, so related events can be connected and investigated. [AU.L2-3.3.5]
4.4 The logging tool can search, filter and report on demand without altering the original records. [AU.L2-3.3.6]
5. Protecting the logs

3.1 Northgate IT monitors, controls and protects traffic at the network's outer boundary and at the boundary around the CUI enclave (cloud email and file storage, and the four CAD/CAM workstations). [SC.L2-3.13.1]
3.2 Network traffic is denied by default and allowed by exception, and the rules are reviewed when systems change. [SC.L2-3.13.6]
3.3 Anything reachable from the internet, such as a web server, sits on its own subnetwork separated from the internal network. [SC.L2-3.13.5]
3.4 Remote devices on the VPN cannot use a second connection to the internet at the same time (no split tunneling). [SC.L2-3.13.7]
4. Design and separation
4.1 New systems and changes are designed with security in mind: proven architectures, secure settings and the least access needed. [SC.L2-3.13.2]
4.2 Administration tools and interfaces are kept separate from everyday user functions. [SC.L2-3.13.3]
4.3 Shared system resources such as shared drives and memory do not pass information between users who should not see it. [SC.L2-3.13.4]
5. Encryption
5.1 CUI is encrypted in transit unless alternative physical safeguards protect it, and at rest wherever it is stored. [SC.L2-3.13.8, SC.L2-3.13.16]
5.2 Cryptography used to protect CUI is FIPS-validated. [SC.L2-3.13.11]
5.3 Northgate IT creates, stores, rotates and retires cryptographic keys under a written procedure. [SC.L2-3.13.10]
5.4 Communications sessions are protected against hijacking and forgery, for example by certificate-based encryption. [SC.L2-3.13.15]
6. Sessions and devices
6.1 Network connections end at the end of a session or after the inactivity period set in each system. [SC.L2-3.13.9]
6.2 Cameras and microphones in meeting rooms cannot be switched on remotely, and show when they are in use. [SC.L2-3.13.12]
6.3 Mobile code (scripts and macros from outside) is limited to what the business needs and is monitored. [SC.L2-3.13.13]
6.4 Internet phone systems (VoIP) are approved, configured securely and monitored. [SC.L2-3.13.14]
7. Evidence we keep
- Network diagrams with the external and internal boundaries
- Firewall rules and VPN settings
- FIPS validation certificates for the encryption used to protect CUI
8. Exceptions and review
Any exception is approved in writing by the approving official, recorded with its reason and end date, and reflected in the system security plan. This policy is reviewed on the cycle above and whenever our systems, contracts or the rules change.
