What is Tailgating? A Stealthy Attack and How to Avoid It

In the world of cybersecurity, we often focus on safeguarding our digital assets from online threats. However, it's crucial to be aware of physical security risks that can compromise our safety and the safety of our organizations. One such threat is "tailgating," a deceptive technique used to gain unauthorized access to secure areas.

What is Tailgating?

Tailgating, also known as "piggybacking," is a social engineering tactic where an attacker gains unauthorized entry to a restricted area by following closely behind an authorized individual. This can occur in various settings, such as office buildings, data centers, or any location with controlled access. The goal of the attacker is to exploit the trusting nature of people or lax security practices to bypass security measures and gain access to sensitive information, equipment, or other valuable assets.

‍

Tailgating can be executed through simple acts of politeness, such as holding a door open for someone, or by pretending to be an employee, contractor, or visitor. The success of tailgating relies on the attacker's ability to blend in and manipulate the situation to their advantage.

Ways to Avoid Tailgating

To protect yourself and your organization from tailgating, consider adopting the following strategies:

‍

1. Implement strict access control policies: Establish clear guidelines regarding access to secure areas, including the use of access cards, key fobs, or biometric authentication. Ensure all employees are aware of and adhere to these policies.‍
2. Educate employees about tailgating risks: Provide regular training to employees about the risks associated with tailgating and the importance of adhering to access control policies. Encourage employees to report any suspicious activity or unauthorized individuals in secure areas.‍
3. Be aware of your surroundings: When entering or exiting a secure area, always be mindful of who is around you. If you notice someone attempting to follow you into a restricted area without proper authorization, politely ask for their credentials or notify security personnel.‍
4. Avoid holding doors open for others: While it may seem impolite, refrain from holding doors open for others when entering or exiting secure areas. Instead, allow the access control system to verify each individual's authorization before granting entry.
5. ‍Utilize security surveillance: Install surveillance cameras at entry points to deter potential tailgaters and provide evidence in case of a security breach.‍

‍

In conclusion, tailgating is a deceptive and often overlooked security threat that can have serious consequences for individuals and organizations alike. By staying vigilant, educating employees, and implementing robust access control measures, you can significantly reduce the risk of falling victim to a tailgating attack. Remember, the key to effective protection lies in a combination of awareness, vigilance, and strong security practices.
