Win7 security features you didn't understand

Windows 7 as Microsoft's next-generation operating system, a new interface, more user-friendly features make operation easier, especially in terms of security than the previous system is more stable and reliable. Today, let's take a look at the security features of Windows 7.

1, UAC (User Account Control)

As we all know, UAC is the first Microsoft operating system Vista, but many Vista users are not suitable for UAC functions. Because UAC's ability to block unauthorized operations is very powerful, suspicious processes are excluded from the kernel and can only be run with user permission.

Comments: Windows 7 has improved the UAC function. Under the premise of ensuring system security, minimizing the number of UAC pop-up prompts does not affect the fluency of the operation. It can be said that UAC is an important part of the Windows 7 security system and a feature that most Windows 7 users are most exposed to.

2, BitLocker (disk lock)

BitLocker driver encryption technology is also a new data protection function in Vista, mainly used to solve data theft or malicious leakage caused by computer equipment loss, etc. problem. Windows 7 modifies BitLocker's potentially exploited vulnerabilities and enhances TPM (Trusted Platform Module) for hardware-based full disk encryption.

Comments: BitLocker's key can be saved on disk or mobile disk, and also supports print and save, suitable for enterprises or individual users with high security requirements.

3, Suite B (Encryption Support)

SuiteB is a secret (SECRET) and top-secret (TOP SECRET) communication that is supported by the National Security Agency (NSA) to support government and military systems. The mandatory cryptographic algorithm. With this algorithm, the NSA believes they can encourage collaboration between US domestic departments.

According to security requirements, it can be divided into 128, 256 or even higher. AES and SHA-256, with 128-bit or 256-bit keys, are designated to protect confidential information from the highest to the secret (SECRET) level. TOP SECRET information requires a 256-bit AES key combined with SHA-384.

Comments: Suite B is a very strict cryptographic algorithm, and Windows 7 adopts such high specification standards in order to improve its security. Previous12Next page Total 2 pages
