Lack of security awareness among Linux users leads to high virus propagation

Article Title: high virus spread due to lack of security awareness of Linux users. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

The Service Investigation and Research Report provided by Symantec, an Internet security enterprise, reveals that enterprises' users' lack of awareness of Linux email server security is a convenient way to spread "botnet virus, in addition, many users running Linux operating systems are infected with "botnets.

The monthly information reports provided by Symantec's Intelligence Lab indicate that, in the personal computer that sends Malicious spam emails, the number of PCs in Linux is five times that in Windows.

Mat Nisbet, a malware data analyst at Symantec's managed service department, posted the message in his personal blog and claims that it plans to dig deeper into the cause. "We conducted a random sampling test on computers that are infected with the virus and run Linux operating systems to test the IP address source that is infected with the virus," he said. In most cases, the IP address source points to a server that runs the open source email proxy service. This shows that many Linux operating system computers are infected by the "zombie virus" mainly because enterprise users operating their own email servers use open-source software to reduce operating costs. However, these enterprise users do not realize that the use of open-source software provides an opportunity for botnets to spread over port 25 ."

Nisbeth also pointed out that some "botnets" on the Internet can automatically search for email servers and PCs with port 25 open, these e-mail servers and PCs that use open-source software are infected with "botnets. "Any user who uses the free advantage of Linux software needs to be vigilant against operating system security. Use Correct security settings to protect your PC from malicious "botnets. Individual users running the Linux operating system need to improve security settings and only provide authorized users with port 25 Access Permissions ."
