SELinux is the abbreviation for "security-enhanced linux", developed by the NSA "nsa=the National security agency" and SCC (secure Computing Corporation) An expanded mandatory access control security module for Linux. Originally developed on the Fluke, it was released in 2000 under the GNU GPL.Most people who use SELinux use SELinux-ready distributions, such as Fedora, Red Hat Enterprise Linux (RHEL), Debia

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. The NSA, with the help of the Linux community, has developed an access control system that, under the constraints of the access control system, can access only those files that are needed in his tasks.

implemented, no longer need to create a "transfer layer" to feed the information to the square default signature system. When no application is special, each application is special. A particularly interesting result: in the design of serenity, Ethereum will have optional quantum security. If you're afraid the NSA will secretly have a quantum computer and want to make your account more secure, you can switch to using Lamport signatures at any time. Th

enough. MD5 (RFC 1321) is an improved version of Rivest in 1991 for MD4. It still groups the input in 512 bits, and its output is 128 bits. MD5 is more complex than MD4, and is slower to calculate, but more secure. MD5 is not safe enough. SHA1 (Secure Hash algorithm) is designed by the NIST NSA, whose output is a Hash value of 160 bits in length, so it is better for anti-poor lifting. The SHA-1 design is based on the same principles as MD4 and mimics

What we are sharing today may be that a lot of people feel that it is not meaningful, but it is not meaningless, but it is more cumbersome to use, because after the SELinux security policy is enabled, each application's access domain and file security tags need to be strictly matched to perform access operations, So if a bit of improper setting, it will cause the application error, but anything is double-sided, it is more cumbersome to set up at the same time, but also to the corresponding appli

Back in the kernel 2.6 era, a new security system was introduced to provide a mechanism for access control security policies. This system is

The preliminary analysis showed that TrueCrypt did not find evidence of backdoor or other malicious code intentionally added. TrueCrypt is a popular encryption software, but has never been audited. After the exposure of NSA large-scale monitoring activities, security researchers initiated a complete security audit of TrueCrypt, which iSEC is responsible. Resea
