Does WannaCrypt Ransomware Infect Linux? Well, the WannaCrypt, or WannaCry ransomware is designed to infect Windows machines that still use the old SMBv1 protocol. This morning though, I saw posted on my Facebook feed an article that Claims that WannaCrypt can infect Linux computers that run WINE. Is it true? Check out the video to see. And, keep checking back for more Linux Security Reports.
File permissions and directory permissions settings work the same on both Linux and Unix. To set either Linux permissions or Unix permissions, just use the chmod command. To change the default permissions settings on file that you want to create, use the umask command. This is good information both Linux systems administrators and Unix systems administrators.
Hopefully, this will help you effectively use linux and unix file permissions.

A few days after I made the video that debunked the notion that WannaCry, or WannaCrypt, could infect Linux machines via WINE, we got news that there's a seven-year-old flaw with Samba, which could possibly allow a remote-code execution attack on Linux and Unix machines. There is a patch available for Linux, so be sure to apply it. This flaw also affect certain NAS devices, so be sure to check with the manufacturer to see if a patch is available for any of them that you might have. Be sure to protect yourself from WannaCrypt for Linux, for proper Linux security.

On home Linux systems, the sudo utility is just as useful as it is in the enterprise Linux setting. Some Linux distros, especially Ubuntu Linux distros, come with full sudo privileges already enabled for the person who installed the operating system. On Red Hat Enterprise Linux 7 class systems, including CentOS 7, Scientific Linux 7, and Fedora, you have the option of adding making yourself an administrator when you install the operating system. On other distros, you may have to give yourself sudo privileges after you've installed the operating system. In this video, we'll look at how to set up sudo privileges on Debian.
