The purpose of these Information Security Policies is to ensure the security and availability of technology systems and networks. It also helps ensure confidentiality, integrity and availability of electronic information captured, maintained and used by the City of Portland. This policy shall be used as a foundation document for all policies, standards, procedures, and guidelines that are developed and implemented by the City, related to information security.
The Information Security Policies are to be "living" documents that will be altered as required to deal with changes in technology, applications, procedures, legal and social imperatives and perceived dangers.
All users (employees, contractors, vendors, and other parties) are expected to understand and abide by these policies.
Authority and Compliance
The Chief Technology Officer (CTO) shall establish and provide authority and governance for information security policies, standards, and best practices for City technology in order to secure all City technology systems and assets and promote the most efficient use of technology resources.
The Information Security Manager (ISM) is responsible for developing and enforcing policies and standards for the implementation and use of information technology security standards and compliance on a Citywide basis.
The City of Portland is a public entity. It has custodial responsibilities for a significant and diverse amount of sensitive information. It holds business contracts with a broad range of public and private organizations. It is the recipient of federal and private grants. It owns, maintains and operates significant critical infrastructures and services including those of public health and safety. All of these facts place significant burden on the City regarding the management and use of its extensive technology resources. Not least among these burdens are compliance requirements with many State and Federal laws, regulations, and promulgated rules. Pursuant to Federal and State regulations, management control of access to law enforcement data, specifically NCIC 2000 and LEDS, is under the authority of the Chief of Police of the Portland Police Bureau.
Beyond strict compliance requirements, the City must also understand and consider several additional government and industry standards and best practices that contribute to the objective of "due care".
In addition to the City’s information security governance and compliance requirements, this policy also reflects the City’s strong commitment to its own institutional ethics and values.
Successful compliance and protection of technology assets requires all business system owners, system operators, data custodians and users of City owned technologies, to learn, understand, and support this City’s information security policy and associated guidelines.
