How to analyze RHEL5 security in depth, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Now all aspects of life have high requirements for security, of course, computer security is the top priority, the discussion of RHEL5 security is also endless, for RHEL5 security, many people still hold the situation of the audience, so here, the author analyzes the problem of RHEL5 security.

Red Hat released the Red Hat Enterprise Linux 5.0 (RHEL5) operating system on March 14th. In previous tests, NetworkWord has tested Novell's SuSE 10 and Microsoft's Longhorn beta.

Red Hat's RHEL5 accords with the development trend of Novell and Microsoft operating system in some aspects, and has some unique performance in RHEL5 security.

Following the routines of Novell's SuSE 10 and Microsoft's Longhorn, RHEL5 introduces two technologies to provide user session control: "enhanced Security Enhanced Linux (SELinux) implementation" and "Xen-based server virtualization technology".

In RHEL5, administrators can combine these two technologies to provide multiple operating system instances, and each instance can run a secure session. This is like a combination of punches, not only with reliability, but also with the security of isolating user sessions from "root access" issues.

In terms of unique performance, Microsoft's current approach is to develop different versions for almost every imaginable server, and Red Hat has reduced the number of versions to two categories: servers and clients, in addition to a further division of 32-bit and 64-bit CPU types. Whether it's a storage server, a certificate management server, or a small business server, Linux is a version.

Despite some minor improvements to GUI, RHEL5 does not provide as many tweaks to GUI as Microsoft and Apple do-Microsoft and Apple constantly adjust GUI to attract users' attention as they upgrade their operating systems.

Security Control of RHEL5 Security

In RHEL5, SELinux access controls are available directly unless you choose not to install them at installation time. Although SELinux is provided in RHEL 4, tests have found that Red Hat has made improvements in the new operating system to make it easier for administrators to set user access control policies, and its SELinux management tools can be used to set user policies and set policies for specific applications on a per-module basis. However, some administrative tasks, such as changing the policy characteristics of the application group, cannot be directly handled by the SELinux utility in RHEL5 and need to be operated in other ways. To its credit, Red Hat provides a very good SELinux Troubleshooter application.

After reading the above, have you mastered how to analyze RHEL5 security in depth? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
