Tailgating in cyber security is a common physical security risk that organizations must address. Tailgating happens when an unauthorized person enters a secure area or system by following someone with permission. This breach, also called piggybacking, relies on human error or trust instead of hacking skills. People may not notice when it occurs, making it hard to spot and stop.
This attack often occurs in places like office buildings, where someone without a badge quickly slips in behind an employee. Attackers might distract or trick people through conversation to get inside secure areas. Tailgating can lead to data loss, theft, or serious security incidents.
Key Takeaways
- Tailgating allows unauthorized entry by following an authorized person.
- Human behavior and weak security measures make these attacks possible.
- Strong physical and digital controls help prevent tailgating.
What Is Tailgating in Cyber Security?
Tailgating in cybersecurity is a physical security risk. It occurs when someone without permission enters a restricted area by following closely behind a person with authorized access.
A tailgating attack often involves social engineering. The attacker may pretend to be an employee or delivery person. They rely on others to hold the door open or not question their presence.
The main danger of tailgating is unauthorized access. Once inside, the attacker can steal data, install devices, or cause other security problems.
Key points about tailgating attacks:
- Involves following an authorized person into a secure area
- Depends on trust or distraction to bypass security
- Can lead to data theft or other harm
Examples of when tailgating might happen:
| Scenario | Description |
|---|---|
| Office Entry | Attacker sneaks in behind an employee |
| Delivery Person | Attacker enters by posing as a courier |
| Open Door | Attacker slips in when a door is left propped open |
Organizations can use security badges, access control systems, and employee training to help stop tailgating. Staff are taught not to let people follow them into secure places without checking credentials.

How Tailgating Attacks Work
Tailgating attacks use social tricks and physical movement to let an unauthorized person enter a secured area. Attackers act as if they belong or ask for help to get past security barriers meant for employees and authorized individuals.
Tailgating Attack Steps
A tailgating attack usually happens in places with controlled access, like office buildings or data centers. The attacker, who does not have permission, waits for an employee or someone with access to use their badge or key to enter.
Often, the attacker follows closely behind the authorized individual and slips in before the door closes. Sometimes, the attacker talks to the employee or asks them to hold the door, pretending to be a delivery driver, contractor, or guest. This social engineering attack relies on trust, kindness, or distraction.
Below is a step-by-step outline:
- Identify a target: Busy entrances or reception areas are common.
- Blend in: Attackers dress like staff, couriers, or visitors.
- Approach an employee: They pick someone likely to open doors without questioning.
- Follow and enter: As soon as the employee opens the door, the attacker slips in, often unnoticed.
These steps let an unfamiliar individual get physical access where they should not be, which can lead to security threats such as stolen data or equipment.
Common Tailgating Methods
Main methods used during tailgating attacks include following closely behind an employee and acting as though they belong, often called piggybacking. Sometimes, the attacker carries boxes, coffee, or other items to make it seem hard to open the door, encouraging others to help.
Pretending to be a courier, service worker, or contractor is also common. Attackers might claim they forgot their badge or need urgent access as a guest. Some attackers engage the employee in friendly conversation to lower suspicion.
Below is a short table of roles attackers might use:
| Role to Pretend | Typical Excuse |
|---|---|
| Delivery driver | Carrying heavy packages |
| IT contractor | Fixing urgent technical issue |
| Guest | Invited to a meeting |
| Service worker | Cleaning or maintenance |
These methods target human behavior rather than technical systems. For more details, see this discussion on tailgating attack methods.
Social Engineering and Tailgating
Tailgating uses social engineering to trick employees into giving access to restricted areas. Attackers rely on trust, common courtesy, and people’s willingness to help.
Psychological Manipulation Techniques
In tailgating, attackers use social engineering techniques to bypass security controls. They may pretend to be delivery workers, maintenance staff, or new employees who forgot their access badge. Attackers take advantage of common courtesy, knowing people rarely question someone who seems like they belong.
Some carry items like boxes or coffee to seem busy, making it more likely someone will hold the door open. They might also create urgency, claiming they are late for a meeting or need to deliver something important.
Social engineering threats such as tailgating differ from digital attacks like phishing. In tailgating, the target is usually an organization’s physical security—not its computer systems.
Targeted Victims
Attackers often target employees in reception areas, entry points, or places with high employee turnover, such as universities or large offices. These locations have many unfamiliar faces, making it easier for outsiders to go unnoticed.
New employees are more vulnerable since they may not recognize all coworkers. Receptionists and security staff must stay alert because they are the first line of defense against tailgating.
Organizations can lower risk by teaching employees to politely challenge unknown people and to follow strict access procedures. Awareness and education are key defenses against these attacks.
Physical Security Measures
Stopping tailgating depends on blocking unauthorized entry before it happens. Good security uses barriers, technology, and careful checking to control who can access restricted areas.
Access Control Systems
Access control systems decide who can enter or leave a building or restricted area. They often use badges or ID cards that employees scan to open doors. These badges are checked by electronic readers.
Turnstiles and locked doors create barriers that only open when the system approves the person’s credentials. In some places, security guards check ID badges for extra verification.
Best practices include anti-passback systems, which stop an ID badge from being used by more than one person to enter the same area. If someone tries to go in twice in a row, the system denies entry.
Access control systems can work with alarm systems to alert security staff if someone tries to enter without permission. Keeping the access list updated is important for security. For more on access control, see this explanation of tailgating and access control systems.
Biometrics and Surveillance
Biometrics use unique body traits, like fingerprints or face scans, to identify people. Biometric scanners are harder to fool than badges, because they check for physical traits that are much harder to copy.
This technology helps ensure only trusted people can enter sensitive areas. If someone tries to sneak in by following another person, they will not pass the biometric check.
Video surveillance, including cameras near entrances, helps watch for suspicious behavior like tailgating. Security staff can monitor live footage or review recordings to spot incidents. Many organizations combine cameras with access controls to respond quickly to problems.
Video records act as a backup, providing proof if someone manages to get past the first layer of security. For more on surveillance and biometrics, see this overview of tailgating and security systems.
Digital Tailgating Threats
Digital tailgating puts personal data and sensitive information at risk. It can lead to cyber threats such as data breaches or give attackers access to private network areas.
Cyber Risks Associated with Tailgating
Tailgating can let attackers into secure systems or buildings by following someone with authorized access. Once inside, they may install malware or ransomware on computers using a USB device or by connecting to the network.
Attackers can also use spyware to steal personal information or monitor user activity. Sensitive data, such as passwords or financial records, can be exposed or stolen. This can result in data breaches with serious consequences for organizations and individuals.
Some key risks include:
- Unauthorized network access
- Theft of sensitive or personal data
- Spread of malware or ransomware
- Loss of sensitive information through spyware
Security training and strong physical controls help lower these risks. For more details, see what a tailgating attack is in cybersecurity.
Consequences of Tailgating
Tailgating in cyber security is a physical security risk that can create major problems for an organization. When unauthorized people enter secure areas, this can result in both immediate harm and long-term consequences.
Financial and Reputational Damage
A tailgating incident can lead to direct financial losses. When someone gains unlawful access, they may steal important assets such as cash, devices, or sensitive data. Restoring, replacing, or protecting these assets can be expensive and might require new security systems.
If sensitive or personal data is stolen, companies may face fines from regulators. Organizations could also lose money if operations are shut down by sabotage or vandalism.
Reputation can be seriously harmed if customers, clients, or partners lose trust. News of a security breach might cause customers to leave or make new clients less likely to join. Lost business and damaged relationships are common after public tailgating incidents.
More information on how theft and data breaches can hurt both finances and reputation is available in this overview of tailgating consequences.
Physical and Digital Security Breaches
Tailgating is a major risk for physical security. Unauthorized people can walk into server rooms, offices, or workspaces. This gives them a chance to steal hardware, copy files, or install malware on company computers.
Intruders may also cause vandalism or sabotage. Sometimes, this leads to ongoing threats like corporate espionage, where secrets are stolen or shared with competitors.
Once inside, attackers may access restricted networks and digital resources. This can lead to cyberattacks, such as spreading malware or stealing passwords, as described in this tailgating attack guide. A single act of tailgating can quickly escalate into a larger security breach.
Preventing Tailgating Attacks
Preventing tailgating attacks requires strong employee education and effective security technology. Both people and tools are important for reducing risks and blocking unauthorized access.
Employee Education and Security Awareness Training
Employees are the first line of defense against tailgating. Regular security awareness training helps workers spot suspicious behavior and teaches them the importance of following security protocols.
Training should cover how to recognize someone who may not belong, such as a person asking to be let in or closely following behind. Employees must avoid letting anyone enter behind them, even if the person seems polite or familiar.
Security best practices include always locking doors, reporting strangers, and never sharing access badges. Reminders like posters or emails can reinforce the message. Real-life scenarios and role-playing during training can prepare workers to respond with confidence.
When employees report incidents, it strengthens the organization’s physical security.
Technological and Procedural Solutions
Technological solutions help control and monitor access to sensitive areas. Systems like key card entry, turnstiles, or biometric scanners make it harder for unauthorized people to enter.
Artificial intelligence (AI) and video analytics can spot unusual movement or detect when two people enter in quick succession. These tools can alert security staff to possible breaches.
Procedures also help. For example, a mantrap or double-door entry system only lets one person in at a time. Regular audits of badge use and camera footage add more control.
Updating security measures helps organizations stay ahead of threats. Combining technology with strong procedures is an effective way to prevent tailgating attacks.
Future Trends in Tailgating Prevention
Organizations are using biometric authentication more often to stop tailgating. This includes fingerprint scans, facial recognition, and iris scans. These methods add security since it is much harder to fake someone’s unique physical features.
Artificial intelligence (AI) is making security systems smarter. AI can analyze camera feeds and detect when someone tries to enter by following another person. Some companies use AI to track entry patterns and spot unusual behavior.
Modern access controls now use a combination of PINs, mobile credentials, or multi-factor authentication. This means more than one form of identity is needed, making it harder for unauthorized people to get in.
Security systems are combining different technologies for better protection. A typical setup might include:
| Technology | What it Does |
|---|---|
| Biometrics | Verifies identity using physical traits |
| AI Video Analytics | Spots suspicious entry behavior |
| Smart Access Controls | Uses multi-factor checks |
These updates make it safer and simpler for authorized users, while making tailgating much harder for outsiders. To learn more, read about tailgating attack prevention.
Frequently Asked Questions
Tailgating attacks happen when someone slips through a secure entry by following an authorized person. This attack can put sensitive areas and information at risk if not addressed.
How does a tailgating attack compromise physical security measures?
A tailgating attack lets an unauthorized person enter a restricted area without proper permission. This often happens when doors are held open for others or there is a lack of strong security checks. The attacker may go unnoticed and gain access to sensitive areas, as explained by Mimecast.
What are the common indicators of a tailgating cyber security incident?
Signs of a tailgating incident include unfamiliar individuals entering alongside employees, doors that do not fully close, or security logs that show extra entries. Tailgaters often try to blend in, making their actions easy to overlook. Watch for people who seem lost or closely follow staff into secure spaces.
How can organizations prevent tailgating from occurring in the workplace?
Organizations can install security doors that close quickly and require badge scans. Security awareness training helps employees know not to let strangers enter. Regular monitoring and surveillance can also catch attempts before someone gets inside, as detailed by DataGuard.
In what ways does tailgating differ from piggybacking in cyber security?
Tailgating usually involves someone entering without the authorized person’s awareness. Piggybacking is when the authorized person knowingly allows another person to follow them. Both can result in security breaches, but the awareness and intent differ.
What measures can individuals take to recognize and avoid tailgating attempts?
Individuals should always make sure doors close securely behind them. They should politely decline to let unknown people follow them into controlled spaces. Reporting suspicious behavior to security also helps keep areas safe.
Why is tailgating considered a social engineering tactic?
Tailgating relies on human behavior, such as politeness or distraction, to bypass security. Attackers use social cues to manipulate authorized individuals into granting access. This is a common method used in physical security breaches, as discussed by TAG Solutions.
