A tamper seal is a device or material that is attached to a computer system’s case to indicate whether the case has been opened or tampered with. The main purpose of placing a tamper seal on a computer system’s case is to detect efforts to open the case, as the seal will be broken or damaged if someone tries to access the internal components of the system. This can help deter unauthorized access, prevent physical damage or theft, and provide evidence for forensic investigation. Raising security awareness is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of reminding users of the importance of physical security. Expediting physical auditing is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of simplifying the process of checking the integrity of the system. Making it difficult to steal internal components is not the main purpose of placing a tamper seal on a computer system’s case, although it may have a secondary effect of increasing the effort and risk of the attacker. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5: Security Architecture and Engineering, p. 409. Official (ISC)2 CISSP CBK Reference, Fifth Edition, Domain 3: Security Architecture and Engineering, p. 298.
