Each module contains one or more secure cryptoprocessor chips to prevent tampering and bus probing, or a combination of chips in a module that is protected by the tamper evident, tamper resistant, or tamper responsive packaging. A vast majority of existing HSMs are designed mainly to manage secret keys.
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
A hardware security module (HSM) contains one or more secure cryptoprocessor chips. [2] [3] [4] These devices are high grade secure cryptoprocessors used with enterprise servers. A hardware security module can have multiple levels of physical security with a single-chip cryptoprocessor as its most secure component.
In police work, tamper-evident techniques must often be used to guard access to evidence, providing means of storing items and samples in a way which can be used to prove that they were not altered after their collection. Special tamper-evident evidence bags are available, to be used following a strict protocol. [6]
A tamper-resistant security module (TRSM) is a device that incorporates physical protections to prevent compromise of cryptographic security parameters that it contains. There are varying levels of protection afforded by TRSMs: Tamper-resistance: make intrusion difficult, usually by employing hardened casing

The only downside is that it's not closed, so things will fall out," wrote one person, but added, "Overall, I would highly recommend this bag and would even consider buying it in different colors."
The pentalobe security screw [1] (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, but not limited to, Apple in their products. [1] Pentalobe screws were adopted by Apple starting in 2009, when they were first implemented in the 15-inch MacBook Pro.
