Bookmark or Share- How can one protect TPM firmware from tampering?First of all: If it actually is ROM, it's tamper-proof. ROM is, electrically, read-only memory. It cannot be changed. Now, it's perfectly possible that the TPM chip runs firmware that is, in fact, in writable memory.
- JWT (Json Web Token) Tampering - Information Security Stack ExchangeIf a malicious actor has a foot on the client device or at any of the hosts that are part of the processing and have access to JWT in clear text (i.e. after SSL transmission), then they can easily tamper the JWT. But, this is only useful when that hosts sends the JWT to another host for further/additional processing.
- tampering - Prove log files weren't tampered with? - Information ...Similar to Esa Jokinen's points, you can further maximize proof that these logs are not being messed around with through ensuring log centralization is set up - such as forwarding logs out to a separate log server or a system (ie a SIEM) that absorbs the logs, processes the logs, using a log collector, etc.
- hardware - Tamper-proof BIOS password & settings storage with Trusted ...Due to this requirement it is a good idea to factor in the real estate required for the TPM at an early stage in the motherboard design and layout process. The TCPA also recommends the provision of a tamper detection mechanism that can provide tamper evidence. An example of a tamper detection mechanism is the use of tamper tape
- Tamper proof SD card - Information Security Stack ExchangeCreating tamper-proof hardware is a very difficult problem. Depending on the attacker’s resources, capabilities and motives, just about any chip’s secrets can eventually be recovered. Instead, consider other solutions to protect your data. You could encrypt the data before you write it to the SD, and not store the decryption key on the card.
