Win7 security features that you have not known (1)

Windows7 as Microsoft's next-generation operating system, a new interface, more user-friendly features make operation easier, especially in terms of security more stable than the previous system. Today, let's take a look at the security features of Windows 7.

1, UAC (User Account Control)

As we all know, UAC is Microsoft's older operating system Vista first, but many users are not suited for Vista UAC function. 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: Windows7 of UAC functionality improvements, under the premise of safety assurance systems, minimize the number of UAC prompts, does not affect the smooth 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 Drive Encryption technology is also new in Vista A data protection, computer equipment is mainly used to solve data loss due to theft or malicious leakage problem. Windows 7 modified BitLocker's potentially exploited vulnerabilities and enhanced TPM (Trusted Platform Module) for hardware-based full disk encryption.

Comments: BitLocker keys can be stored on disk or mobile disk, also supports printing saving, suitable for high security requirements of enterprises or individual users. Forced on (TOPSECRET) communications secret

3, SuiteB (encryption support)

SuiteB was developed by the US National Security Agency (NSA) to support government and military systems (SECRET) and top-secret Password algorithm. With this algorithm, the NSA believes they can encourage collaboration between US domestic departments.

according to security needs of different, can be divided into 128, 256 or even higher level. 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. TOPSECRET information requires a 256-bit AES key combined with SHA-384.

Comments: SuiteB is very strict cryptographic algorithms, Windows7 With such high specification standards but also to make its security upgrade to a higher level.
