Location and Security Design: CPTED

CISSP

Crime Prevention Through Environmental Design (CPTED) is a security concept that involves designing the physical environment in a way that deters criminal behavior. The primary principles of CPTED include:

  1. Natural Access Control
    • Description: This principle involves guiding people’s movement through the environment using design elements such as doors, fences, bollards, and lighting. These elements help define security zones and control access to specific areas.
    • Examples:
      • Doors and Gates: Positioned to direct traffic through monitored entry points.
      • Fences and Bollards: Used to prevent unauthorized access and guide people along designated paths.
      • Lighting: Strategically placed to illuminate entry points and deter unauthorized access.
  2. Natural Surveillance
    • Description: The goal of natural surveillance is to increase the visibility of the area to deter criminal activity. This can be achieved by using security cameras, placing guards in visible locations, and designing spaces so that they are easily observed.
    • Examples:
      • Security Cameras: Placed in strategic locations to monitor key areas.
      • Visible Guards: Positioned in areas where they can easily observe and be observed by others.
      • Open Layouts: Designing spaces with fewer hidden areas and more open sightlines.
  3. Territorial Reinforcement
    • Description: Territorial reinforcement involves using physical designs like walls, fences, and signage to establish ownership and create a sense of space that is defended against intruders.
    • Examples:
      • Walls and Fences: Clearly define the boundaries of a property.
      • Flags and Signage: Indicate ownership and establish the presence of security measures.
  4. Target Hardening
    • Description: Target hardening focuses on reinforcing physical security measures such as locks, cameras, and guards to protect assets and deter potential intruders.
    • Examples:
      • Locks: Strong, tamper-resistant locks on doors and windows.
      • Cameras and Guards: Increase surveillance and physical presence to discourage criminal activity.

Facility Site Security

  • Core of Building: In facility site planning, placing critical areas in the core of a building (e.g., on the 3rd floor of a 6-story building) adds an extra layer of security by increasing the distance from potential external threats and reducing the likelihood of unauthorized access.

Types of Attackers and Motivations

  1. Hacktivists
    • Description: Hacktivists are attackers who combine hacking with activism. They are often motivated by political or social causes and use their skills to promote their agenda, disrupt services, or make a statement.
    • Motivations:
      • Political or Social Causes: Targeting entities they perceive as opponents to their cause.
      • Awareness and Protest: Using cyberattacks to draw attention to their issues.
  2. Thrill Attacks
    • Description: These attacks are carried out purely for the fun of it, driven by the thrill and excitement of breaking into a system. Attackers are often motivated by pride and the desire to brag about their exploits.
    • Motivations:
      • Fun and Excitement: The challenge and thrill of successfully hacking into a system.
      • Pride and Bragging Rights: Gaining recognition in certain circles for their hacking abilities.
  3. Script Kiddies
    • Description: Script kiddies are attackers who lack the technical expertise to create their own hacking tools or attacks. Instead, they rely on pre-written programs and scripts created by more skilled hackers.
    • Motivations:
      • Ease of Use: Using readily available tools to launch attacks without understanding the underlying technology.
      • Desire to Participate: Engaging in hacking activities without needing advanced skills.

Summary

  • CPTED:
    • Natural Access Control: Uses design elements to guide movement and control access.
    • Natural Surveillance: Enhances visibility to deter criminal activity.
    • Territorial Reinforcement: Establishes ownership and defense through physical design.
    • Target Hardening: Focuses on strengthening physical security measures.
  • Facility Site Security:
    • Core of Building: Placing critical areas in the core adds security by reducing exposure to external threats.
  • Types of Attackers:
    • Hacktivists: Motivated by political or social causes, combining hacking with activism.
    • Thrill Attacks: Carried out for fun and excitement, driven by pride and bragging rights.
    • Script Kiddies: Use pre-written hacking tools, lacking the technical skills to create their own attacks.

Understanding these principles and attacker profiles helps in designing secure environments and implementing effective security measures tailored to different threats and motivations.
