Access Control Policy
This policy gives an overview of access control security principles and responsibilities within the Ministry of Justice (MoJ). It provides a summary of the policies and guides that apply to MoJ access management.
To help identify formal policy statements, each is prefixed with an identifier of the form: POL.ACP.xxx, where xxx is a unique ID number.
This policy is aimed at:
These are in-house MoJ Digital and Technology staff responsible for implementing controls throughout technical design, development, system integration, and operation. This includes DevOps, Software Developers, Technical Architects, and Service Owners. It also includes Incident Managers from the Event, Problem, Incident, CSI, and Knowledge (EPICK) Team.
Defined as any other MoJ business group, agency, contractor, IT supplier, and partner who in any way designs, develops or supplies services (including processing, transmitting and storing data), for or on behalf of the MoJ.
All other staff working for the MoJ.
“All MoJ users” refers to General users, Technical users, and Service Providers, as defined previously.
This policy aligns to industry standards and frameworks, and is divided into four security categories (and subsections describing the controls) addressing:
- Business Requirements of Access Controls.
- System and Application Access Controls.
- User Access Management.
- User Responsibilities.
Best Practice Framework - IAAA
Identification, Authentication, Authorisation, and Accounting (IAAA) are the core principles of an Access Control Policy. The principles apply to all security categories described in this policy, as follows:
POL.ACP.001: The MoJ shall provide a unique ID that is assigned, named, and linked to a private account, for each user.
POL.ACP.002: To access MoJ systems, users shall authenticate themselves.
POL.ACP.003: Specifying access rights, privileges, and resources to users shall be granted in line with the principle of least privilege.
POL.ACP.004: Successful and unsuccessful attempts to access systems and user activities conducted while using systems shall be recorded in logs.
Note: If any of the controls within this policy cannot be applied, they are considered an exception to be assessed for inclusion within a risk register.
Business Requirements of Access Control
The MoJ’s business or strategic requirements limit access to MoJ information and information processing facilities, as described in the following subsections.
Access Control Policy
POL.ACP.005: This access control policy shall be established and maintained, based on business and information security requirements, to inform associated standards and guidance, for all users.
POL.ACP.006: The policy shall also follow the additional principles of:
- Non-repudiation of user actions.
- Least privilege.
- User access management.
Access to Networks and network services
This subsection aligns to the principle of least access, to protect a network and network services which are covered in other areas of this policy, specifically:
- Authorisation procedures for showing who (role-based) is allowed to access what, and when. Refer to subsections Information Access Restrictions and Management of Privileged Access Rights.
- Management controls and procedures to prevent access and real-time monitoring. Refer to the categories called System and Application Access Control and User Access Management, with monitoring covered in the subsections called Password Management System and Management of Privileged Access Rights.
System and Application Access Control
POL.ACP.007: The MoJ shall strive to prevent unauthorised access to systems and applications, as described in the following subsections.
Information Access Restrictions
POL.ACP.008: Access to information and application system functions shall be restricted by following access control policies and procedures.
POL.ACP.009: In particular, System Designers and Administrators shall use adequate authentication techniques to identify with confidence user access to their system or data, using the principle of “least privilege”. Refer to the guidance on Authorisation for more detail.
Secure Log-on Procedures
POL.ACP.010: Where required by the access control policy, access to systems and applications shall be controlled by a secure log-on procedure, including the following points:
- POL.ACP.011: Multi-user (MU) accounts shall be managed carefully using PAM or a Bastion server, to avoid accountability type security risks. Refer to the Multi-user Accounts and Public-Facing Service Accounts guidance.
- POL.ACP.012: Front-end users accessing the MoJ’s public services shall authenticate via the GOV.UK Verify Service. Refer to the User Facing Services guidance.
- POL.ACP.013: System Designers for internal systems shall use the MoJ’s single sign-on (SSO) solution to authenticate via an Identity and Access system.
- POL.ACP.014: Passwords shall not be stored or transmitted over the network in clear text, nor be protected with encryption that has known security weaknesses. Refer to the Password Management Guide.
Password Management System
POL.ACP.015: The MoJ’s password management systems shall be interactive, ensure quality passwords are used, and shall store and transmit passwords in a protected form, specifically:
- POL.ACP.016: Systems shall support MoJ password requirements that are provisioned and maintained by System Administrators.
POL.ACP.017: System Administrators shall always have time-bound administrative sessions, which shall be protected using Multi-Factor Authentication (MFA).
POL.ACP.018: The system shall regularly monitor, review, and revoke these sessions when no longer required.
- POL.ACP.019: Strong passwords, separate and unique for each account or service, shall be created and maintained by all users. Refer to the Password Management Guide, Roles and Responsibilities section, Passwords and CyberAware advice.
- POL.ACP.020: Users shall change a password initially received by a system or support team before carrying out MoJ tasks. Refer to Passwords.
- POL.ACP.021: Password history and blocking of commonly guessed passwords shall be enabled in a system. Refer to the Password Creation and Authentication Guide.
- Regular password change is not required, as it is an outdated and ineffective practice.
- POL.ACP.022: Password managers or vaults used at the MoJ shall align to industry standards to securely store and transmit passwords in a protected form. Refer to Password Managers and Password Vaults and Managers.
Note: Contact the Security team if you have specialised needs when selecting or using a storage tool.
Access Control to Program Source Code
- POL.ACP.023: When coding in the open, MoJ Technical users and Service Providers shall follow coding best practices and keep code separate from configuration and data.
User Access Management
User access management ensures authorised user access, and prevents unauthorised access to systems and services. These are described in the following subsections.
User Registration and de-registration
POL.ACP.024: A formal user registration and de-registration process shall be implemented to enable the assignment of access rights, specifically:
- POL.ACP.025: Multi-User (MU) or shared ID accounts shall only be used directly if there is no alternative. Refer to Multi-user Accounts and Public-Facing Service Accounts.
- POL.ACP.026: The identity of the new user shall be confirmed. For all MoJ staff members, this is established as part of pre-employment screening and vetting using the Baseline Personnel Security Standard (BPSS), which is the joint responsibility of HR (performed on their behalf by Shared Services Connected Ltd), and a line manager. Refer to Security Vetting and the BPSS information.
- POL.ACP.027: The hiring line manager shall submit a ServiceNow Order IT role-based access request on behalf of the new user. For example, a list of Role-based access control (RBAC) groups or applications.
- POL.ACP.028: The hiring manager’s line manager (or the budget holder) shall authorise the application for user registration within ServiceNow My Approvals. This confirms the user’s identity, and hence access rights, are correct.
- POL.ACP.029: Confirmation of the Clearance Level shall be initiated by a line manager, and carried out by United Kingdom Security Vetting (UKSV) to recruit new staff (civil servants, armed forces and temporary staff), or staff changing their MoJ roles. Refer to Clearance Levels.
Note: For Contractors or Agency staff, HR/SSCL do not seek assurance that the BPSS check has been completed; instead, the responsibility is with the line manager, via the receipt of the Baseline Personnel Security Verification Record Form, as described here.
POL.ACP.030: De-registration of users shall be at the request of line managers and follow the JML process found here. The following controls need to be adopted for leavers:
- POL.ACP.031: Line Managers shall authorise account removal. The associated leaver’s process can be found on the HR intranet page.
- POL.ACP.032: User accounts and their access rights shall be removed once an individual has left the organisation or no longer requires access to the system(s).
- POL.ACP.033: Existing user accounts shall be reviewed every three months by the System Administrator to confirm those not used in the last three months, and then with MoJ HR to approve accounts for removal.
- POL.ACP.034: Remote access authentication token usage shall be reviewed by the System Administrator every three months, and when a token is identified as unused in the last three months, the account disabled.
- POL.ACP.035: Assigned User roles and privileges shall be reviewed every six to twelve months, and those no longer required removed.
For further information on user de-registration, refer to the MoJ Enterprise Access Control Policy.
User Access Provisioning
POL.ACP.036: A formal user access provisioning process shall be implemented to assign or revoke access rights for all users to all systems and services. Specifically for MoJ, this includes:
- POL.ACP.037: The security clearance required by staff to access specific account types shall align to the MoJ’s UK security clearance levels, as per requirements such as segregation of duties. Refer to Minimum User Clearance Levels guidance.
- POL.ACP.038: MFA shall be used to ensure access to MoJ Information, and is only granted to users once their identity is confirmed. Refer to the Multi-Factor Authentication guidance.
- POL.ACP.039: All MoJ data access shall employ adequate authentication techniques to identify the system or user with confidence, where that system or user requires access to MoJ systems or data. Refer to the Authentication guidance.
- POL.ACP.040: System Administrators shall maintain the MoJ’s systems’ security, with failure to comply compromising the organisational infrastructure.
- POL.ACP.041: System Administrators shall maintain an active list of all active and suspended users, and maintain their access control to services or applications.
- POL.ACP.042: System Administrators shall, on a minimum quarterly basis (rotated with other Admins), conduct an account audit to check:
- Any escalation of privileges from non-administrator to administrator.
- Any forwarding of email accounts.
- Any taking ownership of user accounts.
- POL.ACP.043: A user leaving shall move their data to a shared folder if needed for retention. Refer to the Account Deletion process.
- POL.ACP.044: If anyone with an MoJ account leaves the organisation, system administrators shall retrieve the user’s equipment and suspend the account.
- POL.ACP.045: If a user leaving has not returned all MoJ assets, the line manager shall initially contact the IT Service Desk via Live Chat, or Telephone (0800 917 5148), and raise a security incident, with the following form completed and emailed to firstname.lastname@example.org. Refer to the Leavers checklist for managers for more information.
Note: The previous points are covered by the System Administrators guidance.
Management of Privileged Access Rights
POL.ACP.046: The allocation and use of privileged access rights shall be restricted and controlled using the MoJ’s Access Control Policy. This includes:
- POL.ACP.047: Users shall only use their system administrator account when elevated privileges are required.
- POL.ACP.048: MFA shall be used with privileged accounts, including access to enterprise-level social media accounts.
- POL.ACP.049: Default passwords shall be managed securely and safely by privileged account users, described in the Password Manager guidance. Refer to the Privileged Account Management guidance for more information.
- POL.ACP.050: All users with ownership and use of privileged accounts shall have these secured, controlled, monitored, and audited by System Administrators every month using an industry-standard Privileged Access Management (PAM) tool. Refer to the Privileged Account Management guidance for more information.
Note: Privileged access rights provide a Technical user or a Service Provider with an enhanced level of access to the MoJ’s information systems, compared to a General user. This can include the authorisation to configure networks or systems, provision and configure accounts and cloud instances, and so on.
Management of Secret Authentication Information of Users
POL.ACP.051: The allocation of secret authentication information, such as passwords or encryption keys, shall be controlled through formal management:
- POL.ACP.052: User password management shall be configured, so a password is changed after the initial log-on and invalid if not used in a specified time. Refer to the Passwords guidance.
POL.ACP.053: System Administrators and systems shall never send passwords by email, as it is an unsecured channel.
POL.ACP.054: Instead, users shall receive a time-limited password-reset link or code to their registered email address or phone number. Refer to the Government guidance “Send a link to trigger password resets”.
Review of User Access Rights
POL.ACP.055: System Administrators shall review users’ access rights at regular intervals:
- The review of user access rights is covered in this policy under User Access Provisioning.
Removal or Adjustment of Access Rights
POL.ACP.056: All employees and external party user’s access rights to information and information processing facilities shall be removed upon termination of their employment, contract or agreement, or adjusted when changing their role:
- The removal or adjustment of user access rights is covered in this policy under User Access Provisioning.
Users are required to follow the MoJ’s practices in the use of secret authentication. This is described in the following subsection.
Use of secret authentication information
- POL.ACP.057: All users shall follow the MoJ’s password policy, as referenced in the Password Management System, and the associated tools referenced in the Secure Log-on Procedures.
- This policy is enforced by lower-level policies, standards, procedures, and guidance.
- Non-conformance with this policy could result in disciplinary action per the department’s disciplinary procedures. This could result in penalties up to and including dismissal. If an employee commits a criminal offence, they may also be prosecuted. In such cases, the department will always co-operate with the relevant authorities and provide appropriate evidence.
Note: If you work for an agency or ALB, refer to your local incident reporting guidance.
