Overview of a Physical & Environmental Security Policy
The Physical & Environmental Security Policy exists to establish a set of controls and procedures that protect an organization's physical assets from unauthorized access, damage, and interference. It encompasses everything from access management to environmental controls, ensuring that the organization's physical space is as secure as its digital one.
The policy addresses a range of threats, including unauthorized entry, environmental hazards, and physical damage to assets. It is designed to protect sensitive data, maintain the integrity of network equipment, and ensure the safety of all personnel within the organization.
Key Points of the Policy
The policy is divided into several sections, each addressing a different aspect of physical and environmental security. Below is a summary of the key points from each section:
Access Management Control and monitor who has access to the organization's facilities.
Protection Implement measures to secure sensitive data and network equipment.
Visitor Access Manage and monitor access granted to visitors.
Logging & Monitoring Keep records of access and monitor security systems.
Maintenance Ensure the maintenance of equipment and security systems.
Sanitization & Disposal Properly sanitize and dispose of sensitive media and equipment.
Each of these sections is further broken down into specific controls and procedures, which we will explore in more detail.
