T 0.44 Unauthorised Entry to Premises

If unauthorised persons gain illegal entry into a building or individual premises, this can lead to various other dangers. These include theft or manipulation of information or IT systems. In qualified attacks time is crucial, in which the perpetrators can pursue their goal undisturbed.

Often the perpetrators want to steal valuable IT components or other goods that can be easily sold. However, the target of an intrusion, among other things, can be to gain access to confidential information, perform manipulations or disrupt business processes.

Unauthorised intrusion into premises can thus result in multiple types of damage:

• Damage can occur already due to the very entry into property in an unauthorised manner. Windows and/or doors are forced open and hence damaged, they must be repaired or replaced.
• Stolen, damaged or destroyed equipment or components must be repaired or replaced.
• Damage due to breach of confidentiality, integrity or availability of information or applications can occur.

Examples:

• During a night-time intrusion into an office building the perpetrators did not take a worthwhile trophy. Due to frustration about this, they emptied the powder extinguishers into the offices. The burglary damage was minor, however, the costs of cleaning and work interruptions disproportionately high.
• A break-in into a company during one weekend caused only minor damage due to levering a window open, only one coffee cup stolen and smaller pieces of furniture taken away. During a routine inspection, however, it turned out later that a central server has been skilfully manipulated exactly at the time of the intrusion.
