What is tailgating in IT?
Tailgating is a term that not only plays an important role in the automotive industry, but also in IT security. In IT, tailgating describes the unauthorised entry into a restricted area by a person who infiltrates behind an authorised person. This method can pose considerable security risks for companies, as it is often used to penetrate sensitive company data.
The dangers of tailgating
The dangers of tailgating lie in its simplicity and effectiveness. The attacker can impersonate a legitimate user and gain access to protected areas without going through a secure access system. This can lead to the following problems:
- Theft of confidential information
- Installation of malware or spyware within the company network
- Misuse of resources
How does tailgating work?
Tailgating usually works by exploiting the politeness of employees. Attackers often wait near security gates or entrances and take the opportunity when an authorised person opens the door. For example, the attacker could simply say: "I forgot my ID, could you please hold the door for me?"
Prevention strategies against tailgating
Companies can take various measures to prevent tailgating:
- Security training: Employee training is crucial. Your colleagues need to know the risks and how to act safely.
- Access control systems: Implement access control systems that allow access to be tracked and prevent unauthorised entry.
- Surveillance cameras: Placing cameras at entrances can deter potential attackers while providing evidence of security incidents.
What is the legal framework?
In many countries, there are regulations and laws concerning the protection of data and access to sensitive company areas. Companies are obliged to take appropriate measures to protect their data, which emphasises the need to prevent tailgating.
FAQ on tailgating
What can I do if I notice a tailgating attempt? If a tailgating attempt is detected, security personnel should be informed immediately. It is important to provide the management with all the details and, if possible, to secure evidence.
Illustrative example on the topic: Tailgating
Imagine you are in a modern office building with high security standards. One winter morning, you notice that your company's employee, Mrs Müller, has neglected to take her access badge with her. When she arrives at the access control point, lo and behold, there is a stranger standing behind her, pretending to be a colleague. He says in a friendly manner: "I've forgotten my ID too, could you help me?" Mrs Müller, convinced of the man's authenticity, opens the door and he quickly slips inside. At this moment, the perpetrator has access to confidential information and seriously jeopardises the company's security.
Conclusion
Tailgating represents a serious risk in IT security. By taking preventive measures, companies can significantly improve their security situation and prevent unauthorised access. Information, training and technological tools are crucial to minimising the risk of tailgating and protecting company data.

Frequently asked questions
To prevent tailgating, companies rely on various methods that take both technological and human factors into account. These include the implementation of access control systems that ensure that only authorised persons are granted access. Regular security training for employees is also important to raise awareness of the risks of tailgating. Surveillance cameras at entrances can also act as a deterrent and help to identify potential attackers.
Employees can actively protect themselves against tailgating by always ensuring that they wear their access badges visibly and never open doors for unknown persons. It is important to keep an eye on your surroundings and inform security staff if in doubt. Employees should also be trained to recognise the signs of a possible tailgating attempt and act accordingly.
Security staff play a crucial role in preventing tailgating by monitoring access to sensitive areas and recognising suspicious activity. They are often the first to respond to a tailgating attempt and can quickly take action to prevent unauthorised access. Regular training for security staff is important to prepare them for new tactics used by attackers.
Tailgating can have a serious impact on a company's IT security, as unauthorised persons can gain access to sensitive data and systems. This can lead to data loss, theft of confidential information and the introduction of malware. Companies must therefore take proactive measures to minimise the risk of tailgating and strengthen their security infrastructure.
The frequency of tailgating incidents in companies can vary, but it is a common method used by attackers to gain unauthorised access. Studies show that many security incidents are caused by human error, such as opening doors to unknown people. It is therefore important that companies carry out regular security analyses and train their employees to reduce the risk.
