What Is Tailgating In Cyber Security

It is a deceptive social engineering tactic, exploits human behavior to gain unauthorized access to restricted areas. Unlike typical cyber threats, it doesn’t rely on software vulnerabilities but on the manipulation of individuals.

Tailgating and Piggybacking: What Is Tailgating In Cyber Security

They are both social engineering tactics used to gain unauthorized access to secured premises, but they differ in their execution and intent.

Tailgating: Tailgating involves an unauthorized individual closely following behind an authorized person to gain access to a restricted area. The tailgater typically attempts to blend in with legitimate personnel entering the premises, often using props or engaging in distracting behavior to avoid suspicion. Tailgating relies on exploiting human behavior rather than technical vulnerabilities, and the goal is to gain physical access to a secured location.

Piggybacking: Piggybacking, on the other hand, involves an unauthorized individual exploiting the kindness or lack of awareness of an authorized person to gain entry to a secured area. In piggybacking, the unauthorized individual overtly asks the authorized person to hold the door open or to let them enter alongside them, often under the pretense of being forgetful or in need of assistance. Unlike tailgating, piggybacking may involve more direct interaction with the authorized person and relies on social manipulation rather than blending in.

What are the Most Common Tailgating Methods? What Is Tailgating In Cyber Security

Understanding these common tailgating methods is essential for organizations to bolster their physical security measures effectively.

1. Walking behind employees:
   • This method involves unauthorized individuals closely following behind legitimate employees as they enter secured premises. By blending in with the flow of personnel, tailgaters exploit the assumption that anyone entering alongside authorized personnel must also be permitted.
2. Posing as a courier: What Is Tailgating In Cyber Security
   • Tailgaters may disguise themselves as delivery personnel or couriers, carrying packages or documents as props to appear legitimate. By leveraging the trust associated with delivery services, they aim to gain unchallenged access to restricted areas.
3. Pretending their hands are too full to open doors:
   • Tailgaters often feign difficulty in opening doors due to carrying bulky items or documents. By appearing preoccupied and in need of assistance, they exploit the natural inclination of individuals to hold doors open for others, gaining entry without proper authorization.
4. Claiming to have forgotten their ID:
   • This tactic involves tailgaters approaching entry points and claiming to have left their identification badge or access card behind. They rely on the willingness of personnel to grant them entry out of sympathy or a desire to avoid confrontation.
5. Acting like they were invited:
   • Tailgaters may assert that they were invited to the premises by a colleague or supervisor, exploiting social dynamics and the reluctance of personnel to challenge their claim. This tactic aims to bypass security protocols by leveraging trust and authority.

What are the Dangers of a Tailgating Attack? What Is Tailgating In Cyber Security

1. Unauthorized Access:
   • The primary danger of a tailgating attack is the unauthorized entry of individuals into secure premises. Once inside, these unauthorized individuals can access sensitive areas, systems, or information that they would not otherwise be permitted to access. This can lead to data breaches, theft of intellectual property, or compromise of critical infrastructure.

In high-security environments such as data centers or research facilities, unauthorized access can have severe consequences, including sabotage or espionage.
3. Data Breaches and Loss of Confidentiality:
   • Tailgating attacks can result in data breaches and compromise the confidentiality of sensitive information. Once inside, attackers may gain access to digital assets, proprietary data, or personal information, putting the organization and its stakeholders at risk of financial loss, legal liabilities, and reputational damage.
4. Integrity and Availability Risks:
   • In addition to compromising confidentiality, tailgating attacks can also threaten the integrity and availability of digital assets. Attackers may tamper with equipment, manipulate data, or disrupt operations, causing financial harm, operational disruptions, and loss of customer trust.
5. Compliance Violations:
   • Tailgating attacks may result in violations of regulatory requirements and industry standards related to physical and data security. Organizations found to be non-compliant may face fines, legal penalties, and damage to their reputation, particularly in highly regulated sectors such as healthcare, finance, or government.
6. Reputational Damage:
   • The fallout from a tailgating attack can extend beyond immediate financial and operational consequences. Organizations may suffer reputational damage due to negative publicity, loss of customer trust, and diminished confidence from stakeholders. Rebuilding trust and repairing reputational damage can be time-consuming and costly.
