Tailgating

From Encyclopedia of Cybersecurity

Tailgating

Tailgating is a physical security breach in which an unauthorized person follows an authorized individual into a secured area, such as a building or a restricted area within a building, without proper authentication. Tailgating exploits the natural tendency of people to hold the door open for others, allowing unauthorized individuals to gain entry.

Operation

Tailgating occurs when an unauthorized person closely follows an authorized person through a secure entry point, such as a door or gate. The unauthorized person may do so intentionally, by pretending to be part of a group, or unintentionally, by simply following closely behind someone else. Once inside, the unauthorized person has access to the secure area without having to provide proper authentication.

Risks

Tailgating poses several risks, including:

  • Unauthorized Access: Tailgating allows unauthorized individuals to gain access to secure areas, putting sensitive information and resources at risk.
  • Security Breaches: Tailgating can lead to security breaches, as unauthorized individuals may exploit their access to commit theft, vandalism, or other malicious activities.
  • Compliance Violations: Tailgating can lead to violations of security policies and regulatory requirements, such as those related to access control and data protection.

Mitigation

To mitigate the risk of tailgating, organizations can take several precautions, including:

  • Access Control Systems: Use access control systems, such as key cards or biometric scanners, to authenticate individuals before granting access to secure areas.
  • Security Awareness Training: Educate employees about the importance of security and the risks of tailgating, and encourage them to report suspicious behavior.
  • Physical Barriers: Use physical barriers, such as turnstiles or mantraps, to prevent unauthorized individuals from entering secure areas.
  • Security Guards: Employ security guards to monitor entry points and challenge unauthorized individuals.

Conclusion

Tailgating is a physical security breach that can lead to unauthorized access to secure areas. By implementing access control systems, security awareness training, and physical barriers, organizations can reduce the risk of tailgating and protect their sensitive information and resources.
