4.1.3 Web access protection
Internet connectivity is a standard feature in a personal computer. Unfortunately, it has also become the main
medium for transferring malicious code. Because of this, it is essential that you carefully consider your Web access
protection. We strongly recommend that the Enable web access antivirus and antispyware protection option is
selected. This option is located in Advanced Setup (F5) > Antivirus and antispyware > Web access protection.
4.1.3.1 HTTP, HTTPs
Web access protection works by monitoring communication between Internet browsers and remote servers, and
complies with HTTP (Hypertext Transfer Protocol) and HTTPs (encrypted communication) rules. By default, ESET
Mail Security is configured to use the standards of most Internet browsers. However, the HTTP scanner setup
options can be modified in Advanced Setup (F5) > Antivirus and antispyware > Web access protection > HTTP,
HTTPS. In the main HTTP filter window, you can select or deselect the Enable HTTP checking option. You can also
define the port numbers used for HTTP communication. By default, the port numbers 80, 8080 and 3128 are
predefined. HTTPs checking can be performed in the following modes:
Do not use HTTPS protocol checking – Encrypted communication will not be checked
Use HTTPS protocol checking for selected ports – HTTPs checking only for ports defined in Ports used by HTTPs
