What is Intel TXT?

Intel TXT is a hardware-assisted security technology launched by Intel. It can ensure the integrity and security of the server during startup by establishing a protected space between the CPU and BIOS. The full name of TXT is Trusted Execution Technology, which is Trusted Execution Technology.

Simply put, TXT is a security technology that can provide hardware-level protection to ensure that the server has not been modified by malicious programs or unauthorized software when it is started. This is important because if this happens while the server is booting, malicious programs or software could access or steal important information including passwords and other sensitive data.

Basic Principle

Intel TXT technology relies on chipset and processor hardware-level protection mechanisms that build a trusted execution environment when the server starts. This environment is a protected part at both the hardware and software levels, ensuring that all code and data during startup are intact and secure.

TXT technology can protect the startup process of any software and firmware before the server is put into production, ensuring that they come from a trusted source and have not been maliciously modified. For example, in a virtual machine, TXT technology can ensure that each virtual machine has its own fully trusted execution environment when it starts.

Main advantages

TXT technology has the following main advantages:

1. Higher security: TXT technology can provide hardware-level protection and protect the server during startup Protected from malicious programs and unauthorized software modifications.
2. Prevent malicious attacks: Using TXT technology can avoid attacks by malware or code and maintain a high level of security in server operation.
3. Monitoring certificates and keys: TXT technology can also be used to monitor the integrity of certificates and keys to ensure that they come from a trusted source and have not been tampered with.
4. Support virtualization: In a virtualized environment, TXT technology can provide a separate fully trusted execution environment for each virtual machine.

Summary

Intel TXT technology occupies a pivotal position in the field of server security. It can provide a highly secure protection mechanism at the hardware layer to ensure the integrity and security of the server during startup. TXT technology prevents malware and unauthorized software modifications, protects servers from malicious attacks, and monitors the integrity of certificates and keys. With the continuous advancement of technology, TXT technology will play an increasingly important role and become an important means of server security maintenance.
