This policy articulates the access controls that are required to meet the security objectives of the Enterprise Information Security Policy . Access control management is paramount to protecting Commonwealth Information Technology (IT) Resources and requires implementation of controls and continuous oversight to restrict access.
Commonwealth Secretariats and their respective Agencies, authorities and business partners are required to protect applications, information assets, IT Resources and infrastructure against improper or unauthorized access which could result in compromise of confidentiality, integrity and availability of data and IT Resources.
This policy is organized into the following key sections which map directly to the ISO 27001/27002 Access Control Domain security objectives:
- Business Requirements for Access Control
- User Access Management
- User Responsibilities
- Network Access Control
- Operating System Access Control
- Application and Information Access Control
- Mobile Computing and Teleworking
It is the responsibility of Agency Heads to have the appropriate combination of controls (administrative, technical, physical) in effect that provide reasonable assurance that security objectives are addressed. While an Agency Head may delegate this responsibility, the Agency Head remains accountable. Secretariats and their respective Agencies must achieve compliance with the overall information security goals of the Commonwealth, including compliance with laws, regulations, policies and standards to which their technology resources and data, including but not limited to personal information, are subject.
All Secretariats and their respective Agencies and entities governed by the overarching Enterprise Information Security Policy must adhere to requirements of this supporting policy as described below.
- Any entity that uses ITD-controlled resources to access the Commonwealth's wide area network (MAGNet);
- Executive Department Secretariats and their respective Agencies, in addition to any agency or third party that connects to the Commonwealth’s wide area network (MAGNet), must comply with this policy;
- Executive Department Secretariats and their respective Agencies are required to ensure compliance by any business partner that accesses Executive Department IT Resources or shared environments, e.g. MAGNet;
- Executive Department Secretariats and their respective Agencies are required to ensure compliance by third parties in any aspect of the process of providing goods and services to their agency. These include, but are not limited to, electronic data collection, storage, processing, disposal, dissemination and maintenance. Third parties that interact in any way with Executive Department Commonwealth IT Resources, e.g. MAGNet, are required to comply with this policy; and
- Executive Department Secretariats, and their respective Agencies must develop and/or maintain an access control policy (including remote access) that documents Secretariats’ and their respective Agencies’ methodologies for providing access to authorized users either traditionally or remotely.
Other Commonwealth entities are encouraged to adopt, at a minimum, security requirements in accordance with this Enterprise Access Control Policy or a more stringent agency policy that addresses agency specific and business related directives, laws, and regulations.
The objective of this policy is to address the considerations that will help to ensure that the Commonwealth’s IT Resources and information assets are properly protected against unauthorized access, while meeting the access requirements for all authorized users. Critical to achieving this objective is the implementation of controls that address each of the requirements stated in this policy.
Executive Department Secretariats and their respective Agencies are required to implement necessary controls for providing authorized access and preventing unauthorized access to IT Resources and information assets on the basis of business, MGL, and security requirements.
1. Business Requirements for Access Control: The objective of this requirement is to ensure that business, legal and security requirements drive the authorization process and access to IT Resources and information assets.
1.1. Access control policy: Secretariats and respective Agencies must have a documented and periodically reviewed access control policy based on business and security requirements for access.
1.1.1. Access to IT Resources and information must be commensurate with the security requirements of that resource and the classification of data it provides access to.
1.1.2. Authentication methods used for accessing IT Resources and information must be consistent with the Security Controls articulated in the Data Classification Standards .
2. User Access Management: The objective of implementing user access management is to ensure that authorized users are able to access information and resources while unauthorized users are prevented from access to the same.
2.1. User Registration
Secretariats and their respective Agencies must implement a formal user registration and de-registration procedure for granting and revoking access to all information resources and services.
2.2. Privilege Management
Access control rules must take into account existing policies for information dissemination and authorization while incorporating the principle of least privilege which grants the lowest level of access, rights, privileges, and security permissions needed for the performance of authorized tasks to any IT Resource or information.
Access Control rules must differentiate between different roles that may be applicable for an individual commensurate with the classification of the resources. For example, a general user who accesses information from a web site, the individual responsible for updating the content on a web site, the administrator of the application, and the network hosting administrator each have different roles that necessitate different privileges.
Acceptable implementation of this principle will include allocation of user privileges on a need-to-use basis, per system, per application, based on resource and data classification, business requirements, and job function.
2.3. User Password Management
Secretariats and their respective agencies must have a password policy and a formal process for password management and maintenance, along with a formal process to review the password policy and process periodically. The password policy, to the greatest extent technically feasible, should comply with NIST and FISMA standards, which specifically call for a password being comprised of at a minimum of eight characters, including capital and non-capital letters, numerical and special characters.
2.4. Review of User Access Rights
Secretariats and their respective Agencies must establish procedures and controls that cover all phases in the life-cycle of user access, authorization and privileges from provisioning to de-provisioning.
3. User Responsibilities: The objective of implementing user responsibility controls is to foster an informed and co-operative approach between users and the organization’s management for protecting IT Resources and data from unauthorized user access.
Executive Department Secretariats and their respective Agencies are required to obtain written user acknowledgement regarding the responsibilities associated with new access privileges prior to providing access credentials to the end user.
3.1. Password Use
Users are responsible for handling, use and storage of passwords in a manner that complies with all password management requirements noted in section 2. On addition:
3.2. Unattended User Equipment
Users are responsible for ensuring that unattended equipment has appropriate protection.
3.3. Clear desk and clear screen policy
Users are responsible for ensuring that information contained in papers and removable storage media on their desks, as well as information on their computer screens, has appropriate protection.
4. Network Access Control: The objective of Network Access Control is to provide access to internal and external networked systems in a controlled manner that is consistent with security policies.
Access to Commonwealth internal and external networked services via MAGNet must be protected through a combination of security controls including network segmentation, deployment of firewalls and other security appliances and appropriate authentication mechanisms to prevent and detect unauthorized access while providing secure access to authorized users and systems.
4.1. Policy on use of Network Services
Access to any given network service must only be granted to users who are specifically authorized to use that particular service.
4.2. User Authentication for External Connections:
Approved statewide remote access methods must be used for and by employees, contractors, contracted business partners, and statutory business partners.
4.3. Equipment Identification in Networks
Whenever possible, connections from specific locations and equipment must be authenticated using automatic equipment identification.
4.4. Remote Diagnostic and Configuration Port Protection
Any IT Resource that has a remote diagnostic or configuration service or facility must be evaluated to validate the need for remote access functionality.
4.5. Segregation in Networks
Secretariats and their respective Agencies must adopt a segmented approach to separate logical network domains.
4.6. Network Connection Control (flow control)
Users’ capability to connect to the Commonwealth shared network must be restricted according to access control policy and business application requirements.
4.7. Network Routing Control
Secretariats and their respective Agencies must implement network routing controls that enforce the network’s access control policies.
5. Operating System Access Control: The objective of implementing operating system access controls is to enable the ability to restrict access to operating systems to only authorized users.
Secretariats and their respective Agencies must have policies and procedures in effect to prevent unauthorized access to operating systems by employing controls that will properly authenticate users, provide appropriate access by role (e.g. Administrator), log activities, and generate notifications in the event of a breach.
5.1. Secure Log-on Procedures
Secretariats and their respective Agencies must adopt login procedures that minimize the opportunity for unauthorized access by implementing Security Controls.
5.2. User Identification and Authentication
Secretariats and their respective Agencies must ensure that User Identification and Authentication controls support the security objectives of the system or environment.
Secretariats and their respective Agencies must have procedures and controls in place that utilize authentication controls of strength commensurate with the sensitivity of the system and data accessible by authenticated users where appropriate, e.g. cryptographic means, smart cards, tokens or biometric means.
5.3. Password Management System
Secretariats and their respective Agencies must enforce policies and implement an effective password management system in accordance with the requirements of sections 2.3 and 3.1 of this policy.
5.4. Use of System Utilities
Secretariats and their respective Agencies must have system policies and procedures in place to tightly control access and permissions associated with utility programs including those that might be capable of overriding system and application controls.
In order to accomplish this, Secretariats and their respective Agencies must control the use of System Utilities using identification, authentication and authorization procedures.
5.5. Session Time-out
Secretariats and their respective Agencies must have system policies and procedures in place to shut down inactive sessions after a defined period of inactivity. Use of Session Time-out functionality must be consistent with the Security Controls articulated in the Session Time-out section of the Enterprise Access Control Standards.

Use of connection time-based limitation functionality must be considered for systems and environments classified as having high sensitivity or high risk.
6. Application and Information Access Control: The objective of implementing application and information access control is to enable enforcement of access policies for information and system functions, protect against unauthorized access and prevent compromise of systems with which information resources are shared.
Secretariats and their respective Agencies must have policies and procedures in effect to prevent unauthorized access to application systems, application system functions, information contained within the applications and integrated sub-systems. Effective controls include use of layered security techniques, security controls, and standards to protect against compromise from any unauthorized access including but not limited to interactive users, applications, application services, etc.
6.1. Information Access Restriction
Secretariats and their respective Agencies must have access policies and procedures in effect to manage access to information and application system functions in accordance with both Enterprise and Secretariat and Agency policies. These policies and procedures must reflect the Enterprise Access Control Standards. All applications should follow current generally accepted control practices as promoted by respected security organizations including, but not limited to those published by The International Organization for Standardization (ISO), The National Institute of Standards & Technology (NIST), and The SysAdmin, Audit, Network, Security Institute (SANS), etc. Best practices such as these should form the basis of these policies and procedures.
6.2. Sensitive System Isolation
Secretariats and their respective Agencies must isolate systems containing data that is classified as having high sensitivity, e.g. FTI, PII, HIPAA, etc. Entities must have controls in effect to ensure that systems utilizing the public access architecture are properly secured and compliant with this policy and related standards. Entities need to ensure that appropriate monitoring mechanisms are in place to provide reasonable assurance that established controls are in effect. The isolated computing environment must protect an application system based on the explicitly identified and documented sensitivity classification and associated requirements as documented by the application owner. The isolated computing environment must also only be physically accessible to personnel that are approved such access by their respective Secretariat or Agency SCIO on an annually reviewed basis.
