Permission Types for Website Security
It is important to know that lots of your directories and files are required to have the right kind of permissions, if you have a website on a Linux or UNIX server. The procedure of giving permissions, in the world of Unix-like platforms, is referred to as the ‘change mode’ or the CHMOD. Read, Write and Execute are the three types of permissions in the UNIX environment. These permissions apply to three types of users such as the User, Group and Other. On a UNIX server files are usually set to 644 by default. On the other hand, the directories are usually set to 755.
