The security features that UNIX-like systems such as Linux rely on are making these systems clearly superior to the rest of OS’s on the market. These features encompass root account security measurements, enhanced file accessing options, advanced data verification, storage encryption and the list is not an exhaustive on. You can choose to watch now a surf shop be launched over the internet and expect for your Linux OS to better cope with the new website, rather than a Windows system, for instance.
First of all, all UNIX-like systems feature their very own root account, which stands for the single, unique account that can undergo administrative functions. The rest of the accounts on such a system are to be regarded as being unprivileged. In other words, these unprivileged accounts will not be able to bring users access to those files that are marked with appropriate permissions. Also, they will not enable users to launch any network services either. Searching for such access is similar to an unsuccessful cerco casa or serviced apartments in the center of Rome at low rates scenario.
As for the network ports, again, only the root account is able to launch network services that use port numbers that are lower than 1024. As for the rest of the accounts, any of them could start network services using port numbers that are higher than 1024. Users should create their own account and they should also create separate accounts for network services, so that access to system files can be done more easily.
Moreover, most UNIX-like systems are using a Pluggable Authentication Module which enables them to facilitate user access. All login attempts and all password changes will automatically trigger the previously configured PAM module in sequence.
As for file permission, all files and directories pertaining to a UNIC system are marked with three sets of file permissions. These permissions are used to establish the way these files can be accessed and the person who is entitled to access them, be it the owner, the group or other people. Each of these special sets of permissions could allow one to read, write and/or execute files or directories.
Most UNIX-like system files are usually owned by the root account, and the root account has the right to restrict or completely block access from the rest of the accounts. If one chooses not to modify these preset permissions, he or she will benefit from the advantages of this Linux security feature just like some people get to benefit from free government cell phones.
The Linux company ratings are currently going through the roof, as, officially, Linux has gone pro and it is not afraid to constantly boost its security features and cater to huge companies’ needs.
