Snort is now recognized as the best IDs on Linux . Using SELinuxSELinux is used to secure Linux, and with it, users and administrators can gain more control over access control. SELinux adds finer granularity control to access control. Unlike the ability to specify only who can read, write, or execute a file, SELinux lets you specify more control over who can delete links, append only, move one file, and so on. LCTT: Although the NSA has contribu

Recommended to close, as for security issues, you can find another way.

Therefore, when building a hash table, you should

SELinux (security-enhanced Linux) is the United States National Security Agency (NSA) implementation of mandatory access control, is the most outstanding new security subsystem in the history of Linux. Under the restriction of this access control system, the process can only access files that are needed in his tasks. SELinux is installed on Fedora and Red Hat Enterprise Linux by default.Although SELinux works well, in most cases we turn it off because

In contrast, closed-source software is easier to place back doors or traps, and the NSA key found in the Windows operating system is compelling evidence. Open source can bring security Closed-source software is no better than the security of Open-source software, and, conversely, OSS has the capacity and potential to provide better security, as evidenced by the following examples: OpenBSD, currently o

The SHA-1 design is based on the same principle as the MD4 and imitates the algorithm. So what's the use of these hash algorithms? The application of hash
