Monitoring Incoming Data

[subornaakter20]

To ensure the security of a website, it is necessary to check all data that comes to it. This is done by a firewall (WAF - web application firewall), which is a filter between the site and information coming from outside. It scans it, blocking malicious code and letting through only safe requests. Firewalls can operate at the DNS level (traffic goes through a proxy server), client server or CMS plugin. The first type is considered the most secure.

For WordPress sites, which are most often attacked via data entry forms, use Wordfence Security, Sucuri Security or iThemes Security.

4 - reading,

2 - record,

1 - execution.

Rights are formed by addition: 4+2= 6 (read and write), 4 (read only), 4+2+1=7 (full access), etc.

Users are divided into three groups :

u - administrator,

g — administrative group,

- the rest.

Combinations of letters and numbers are formed, which indicate the features of access to the site. For example, 754 can be written as rwx-rx-r, this code will provide full rights to the administrator, reading and executing the file (entering the folder) to the administrative group, only reading to others. You should set the codes 755 for folders and 644 for files.

Limitation of user rights

Access rights are changed using the free FTP client FileZilla. To do this, download the program, then right-click on the file and select "file access rights".
