1 Policy Statement
To meet the enterprise business objectives and ensure continuity of its operations, XXX shall adopt and follow well-defined and time-tested plans and procedures, to ensure the physical security of all information assets and human assets. Physical security is an essential part of a security plan. It forms the basis for all other security efforts, including personnel and information security. A balanced security program must include a solid physical security foundation. A solid physical security foundation protects and preserves information, physical assets, and human assets.
The purpose of the Physical Security Policy is to:
- establish the rules for granting, control, monitoring, and removal of physical access to office premises;
- to identify sensitive areas within the organization; and
- to define and restrict access to the same.
This applies to all employees, contractual employees, trainees, privileged customers and all other visitors.
The Physical Security Policy documentation shall consist of Physical Security Policy and related procedures & guidelines.
3.3 Document Control
The Physical Security Policy document and all other referenced documents shall be controlled. Version control shall be to preserve the latest release and the previous version of any document. However, the previous version of the documents shall be retained only for a period of two years for legal and knowledge preservation purposes.
Records being generated as part of the Physical Security Policy shall be retained for a period of two years. Records shall be in hard copy or electronic media. The records shall be owned by the respective system administrators and shall be audited once a year.
3.5 Distribution and Maintenance
The Physical Security Policy document shall be made available to all the employees covered in the scope. All the changes and new releases of this document shall be made available to the persons concerned. The maintenance responsibility of the Physical Security Policy document will be with the CISO and system administrators.
The Physical Security Policy document shall be considered as “confidential” and shall be made available to the concerned persons with proper access control. Subsequent changes and versions of this document shall be controlled.
The CISO / designated personnel is responsible for the proper implementation of the Physical Security Policy.
