1. Purpose

2. Scope

  • 2.1

    This PIN applies to Government of Canada (GC) electronic networks for unclassified information only. Internet-based tools and services are not to be used for communicating or storing sensitive information unless approved by the institution’s security and technical authorities.

3. Effective date

  • 3.1

    This PIN is effective as of .

4. Application

  • 4.1

    This PIN applies to all departments that are subject to the Policy on Acceptable Network and Device Use.

    Departments, agencies and organizations in the Government of Canada not subject to the Policy on Acceptable Network and Device Use are encouraged to abide by this PIN to the extent possible.

    The heads of the following organizations are solely responsible for monitoring and ensuring compliance with this PIN within their organizations:

    • Office of the Auditor General
    • Office of the Chief Electoral Officer
    • Office of the Commissioner of Lobbying of Canada
    • Office of the Commissioner of Official Languages
    • Office of the Public Sector Integrity Commissioner of Canada
    • Offices of the Information and Privacy Commissioners of Canada

5. Context

  • 5.1

    The GC recognizes that open access to modern tools is essential to transforming how public servants work and serve Canadians. Open access to the Internet, including access to GC and external tools and services:

    • enhances communication and digital collaboration
    • encourages sharing of knowledge and expertise to support innovation

    When equipped with the right tools, public servants can work more effectively. The GC must adapt to meet the demands and expectations of its clients, stakeholders, partners and employees.

  • 5.2

    The GC must also apply adequate security controls to protect users, information and assets. When access to collaboration tools and sites is restricted, instead of increasing protection, the opposite occurs. Users will find a way around the blocks if it makes their life easier. From the standpoint of IT security, connections to external tools and services are not substantially different from other connections to the Internet. Security is more than just locking things down; user experience must also be considered.

  • 5.3

    Adopting a balanced approach that considers user needs, supported by a pragmatic security program, will result in a more secure environment. Instead of banning access to certain tools and sites, making access open by default and encouraging the secure use of these tools and services will result in risks being better controlled. Consideration of the departmental risk profile and the department’s culture, mission and business objectives, and the threats that pertain to the departmental business activities, will also help determine the proportionate security measures needed to ensure the adequate protection of GC information.

6. Direction

  • 6.1

    Departments are to enable open access to the Internet for GC electronic networks and devices, including GC and external Web 2.0 tools and services, to authorized individuals, as per Section 6.1.3 of the Policy on Acceptable Network and Device Use (PANDU).

  • 6.2

    To ensure a consistent user experience government-wide while taking into consideration the departmental risk profile, departments are to reconfigure their web filtering rules to be open by default to the Internet, except for websites that support non-acceptable activities or behaviours which, as per Appendix C of PANDU:

    • are criminal or otherwise unacceptable
    • violate Treasury Board or other organizational policies, codes of conduct and other published requirements
    • impact negatively the performance of GC electronic networks and devices
    • impede organizational operations or the delivery of services
    • breach the “duty of loyalty” requirement for public servants
  • 6.3

    Departments are expected to apply web filtering rules in accordance with Appendix A of this PIN, which provides the baseline set of website categories that are to be blocked in order to comply with legal and policy requirements. All other categories, including social media and web-based collaboration or chat tools, are to be open by default. When departments limit access outside these categories, they are expected to take a risk-based approach and document a rationale for limiting such access, approved by the departmental Chief Information Officer.

  • 6.4

    Departments are responsible for ensuring continued compliance with the Policy on Government Security and Appendix E (Departmental Considerations for Security) of PANDU and are encouraged to analyze departmental security needs and implement additional security considerations (outlined in Appendix B of this PIN) to mitigate risk to an acceptable level, according to the departmental risk profile.

  • 6.5

    SSC is responsible for managing web filtering tools for departments that receive their network services from SSC, as per Section 6.2 of PANDU. However, as legacy web filtering solutions were inherited from partner organizations, SSC’s ability to monitor and report is not consistent for each SSC customer. SSC is investing in an enterprise web filtering capability which will provide a better ability to monitor and report as networks evolve from the legacy infrastructure to the SSC enterprise service. SSC customers requiring information on the reporting capabilities of their web filtering service are to contact SSC.

7. Enquiries

  • 7.1

    For interpretation of any aspect of this PIN, contact Treasury Board of Canada Secretariat Public Enquiries.

  • 7.2

    Individuals at departments should contact their departmental information technology group for any questions regarding this PIN.

  • 7.3

    Individuals from a departmental information technology group may contact their SSC Service Delivery Management Executives for information related to their web filtering service.

  • 7.4

    Individuals from a departmental information technology group may contact the TBS Cyber Security (ZZTBSCYBERS@tbs-sct.gc.ca) mailbox for interpretations of this PIN.

Appendix B: security considerations

Departments should apply a defence-in-depth approach, implementing measures in accordance with the threat, to manage security risks to GC electronic networks, devices and information, while balancing user needs. The following actions are recommended when enabling access to the Internet and web services:

For managers

  • Ensure that staff:
    • understand their obligation to safeguard information and assets
    • never use external Web 2.0 tools and services for communicating or storing sensitive information unless the service is approved by the institution’s security and technical authorities
  • Update guidance on information management to:
    • include best practices and describe how they apply to the use of public websites, tools and services, in accordance with Policy on Information Management
    • indicate that when information of business value is transmitted or created via GC and external Web 2.0 tools and services, the information:
      • must be capable of being extracted and documented in another format (for example, an email message or a Word document)
      • must be stored and retained in an official corporate repository
      • is subject to Access to Information and Privacy (ATIP)
  • Encourage staff to:
    • use versions of tools that have features that provide:
      • increased security assurances (for example, two-factor authentication)
      • information management controls (for example, export functionality, retention policies)
    • review terms of services to understand how their data will be used and how it will be accessed
    • use a GC email address when accessing tools solely for professional use, as doing so will help information management practices be applied
  • Remind staff:
    • to not reuse the same passwords that are used for their internal corporate credentials
    • to use strong authentication mechanisms (for example, multi-factor authentication) where possible to protect information from unauthorized access

For IT personnel

  • Implement modern operating systems and web browsers that are:
    • maintained with up-to-date software
    • configured with appropriate host-based protections
  • Filter traffic at the host or network level to mitigate threats from malicious websites and related attacks, and provide a clear rationale when blocking categories that are not included in Appendix C of PANDU
  • Leverage the defensive services of Shared Services Canada and the Communications Security Establishment (CSE) by using managed Internet gateways in accordance with CSE’s Top 10 IT Security Actions
  • Monitor and review reports from web filtering services for unusual or suspicious activity
  • Apply additional safeguards such as tools to prevent the loss of data, when justified by a risk assessment, taking into consideration cost and complexity

Appendix E of PANDU includes a non-exhaustive list of measures that can be applied to further mitigate potential threats. The Guideline on Acceptable and Network Device Use provides additional guidance to departmental managers and functional specialists responsible for implementing PANDU.
