## Physical Tamper Resistance

Physical Tamper Resistance refers to the design features of hardware devices intended to detect, prevent, or respond to physical attempts to access internal components. This includes epoxy potting to prevent probing, light sensors to detect case opening, and voltage monitoring to stop side-channel analysis.

In financial security, this ensures that even if an attacker gains physical possession of a device, they cannot extract the cryptographic keys stored within. It is a vital component of hardware wallets and security modules used in high-stakes financial environments.

These mechanisms are often certified by international standards to prove their effectiveness against advanced forensic attacks. They act as the final line of defense against physical adversaries.
