In this article, we will discuss the process of the setup of the advanced security setting.

Advanced security settings:

Spoofing and authentication—Protection against spoofing a domain name, employee names, email impersonating your domain, and unauthenticated email from any domain (indicated by a question mark next to the sender’s name).
Attachments—Protection against encrypted attachments and scripts from untrusted senders.
Links and external images—Identify links behind short URLs, scan linked images for malicious content, and display a warning when users click links to untrusted domains.

With advanced settings, you can:

Disable all settings—Disable all security settings for a domain or organizational unit.
Enable all settings—Turn on current (and any future) settings. This option provides the strongest level of protection for a domain or organizational unit. When you select Enable all settings, the default action associated with each option is applied.
