A tailgating attack in cyber security is a physical security breach where an unauthorized person gains entry into a restricted area by closely following an authorized individual. This attack relies on human error rather than hacking or technical vulnerabilities. Unlike technical cyber threats such as malware and phishing, tailgating exploits human behavior and lapses in physical security protocols to infiltrate organizations undetected. Organizations that fail to implement strong physical security controls are at high risk of breaches that could lead to other kinds of attacks, such as malware or phishing attacks.
While physical tailgating attacks involve unauthorized access to physical premises, a digital tailgating attack refers to unauthorized individuals gaining access to devices, systems, or networks due to negligence or security lapses. Unlike hacking attempts that exploit software vulnerabilities, digital tailgating relies on human errors and weak access controls.
Stolen or Unattended Laptops: Attackers may steal a logged-in laptop or access a device left unattended in a public space.
Shoulder Surfing: Cybercriminals spy on employees entering passwords or accessing sensitive data in public areas like cafes, airports, or coworking spaces.
Accessing an Unlocked Workstation: An unauthorized individual gains access to a company network by using a workstation that was left unlocked.
Exploiting Open Wi-Fi Networks: Attackers intercept communications by connecting to unsecured public or corporate Wi-Fi networks.
Once an attacker gains digital access, they can:
Steal sensitive data, such as customer records and intellectual property.
Inject malware, ransomware, or spyware to compromise company systems.
Manipulate or delete critical files to cause operational disruptions.
Use compromised credentials to access internal databases or cloud applications.
Digital tailgating is often overlooked as a cybersecurity risk, but it can be just as damaging as a traditional cyberattack if not mitigated effectively.
Attackers use social engineering tactics to trick employees into granting them access to restricted areas. They may:
Dress as security personnel, IT staff, or maintenance workers to gain trust.
Claim to be a new employee who forgot their access card.
Use emotional manipulation, such as pretending to be in distress or pretending to be a delivery driver and deliberately have their hands full when approaching a door to manipulate an employee.
Many tailgating incidents do not involve force or technical exploits, attackers can simply attempt to exploit the natural inclination of people to be helpful. An employee could:
Hold a door open for a stranger without verifying their credentials.
Leave their workstations or devices unattended in shared spaces.
Fail to question unfamiliar individuals in secure or unauthorized areas.
These seemingly small security lapses can create entry points for cybercriminals and malicious insiders.
Tailgating can lead to unauthorized access to sensitive data, resulting in financial losses, reputational damage, and legal liabilities.
Attackers may steal or tamper with company laptops, hard drives, or USB devices, potentially leading to the exposure of confidential data.
Unauthorized individuals can physically or digitally introduce malware into a company’s network, leading to system compromise, data loss, or ransomware attacks.
Tailgaters may damage or disrupt critical infrastructure, leading to downtime, financial losses, or operational failure.
While both tailgating and piggybacking involve an individual gaining unauthorized access to an area but the key distinction lies in consent and awareness.
Tailgating occurs when an unauthorized person gains entry by closely following an authorized individual without their knowledge while Piggybacking happens when an authorized individual knowingly allows an attacker to enter a restricted area, often out of courtesy or without verifying credentials. This could involve an employee holding the door open for someone who appears to be a visitor or coworker, assuming they have permission to enter. Both tactics are used in social engineering and can be a serious security threat.
Organizations can reduce the risk of tailgating attacks by implementing proactive security measures, such as:
Implement Access Control Systems: Implement the use of biometric authentication, keycards, and turnstiles to restrict unauthorized entry.
Use Security Guards and Checkpoints: Ensure security personnel verify credentials before granting access to individuals.
Install Anti-Tailgating Doors: Deploy security doors that allow only one person to pass at a time.
Conduct Security Awareness Training: Educate employees on the dangers of tailgating and how to recognize social engineering tactics.
Promote a "Challenge Culture": Encourage employees to question and report unauthorized individuals.
Enforce the "No Badge, No Entry" Policy: Require all employees and visitors to display identification at all times.
Implement Zero Trust Security Measures: Regularly verify identity and access requests before granting entry.
Deploy CCTV Cameras and Motion Sensors: Monitor high-risk entry points to detect suspicious activities.
Use AI-Powered Surveillance Systems: Identify unusual behaviors and trigger security alerts in real time.
By implementing these security measures, organizations can strengthen their overall security measures against attackers using tailgating tactics to gain unlawful access to sensitive information.

The risk of tailgating attacks can be reduced by implementing proactive security measures, such as Physical Security Measures, Employee Training and Awareness, Security Protocols and Policies and Video Monitoring and Surveillance. By adopting these security measures, organizations can enhance their overall protection against attackers who use tailgating tactics to unlawfully access sensitive information.
Tailgating tactics often involve an attacker slipping into a building by closely following someone as they enter, taking advantage of an open door. Another method includes gaining physical access to a victim's computer or device after they have logged into a secure system, allowing the attacker to exploit their access for malicious purposes.
Tailgating happens when an unauthorized person sneaks into a restricted area by closely following an authorized individual without their awareness. In contrast, piggybacking occurs when an authorized person knowingly grants access to someone without proper verification, often out of politeness or a lack of security awareness.
