Threat logs display entries when traffic matches one of the Security Profiles attached to a security rule on the firewall. Each entry includes the following information: date and time; type of threat (such as virus or spyware); threat description or URL (Name column); source and destination zones, addresses, and ports; application name; alarm action (such as allow or block); and severity level.

The following table summarizes the Threat severity levels:
Serious threats, such as those that affect default installations of widely deployed software, result in root compromise of servers, and the exploit code is widely available to attackers. The attacker usually does not need any special authentication credentials or knowledge about the individual victims and the target does not need to be manipulated into performing any special functions.
Threats that have the ability to become critical but have mitigating factors; for example, they may be difficult to exploit, do not result in elevated privileges, or do not have a large victim pool.
Minor threats in which impact is minimized, such as DoS attacks that do not compromise the target or exploits that require an attacker to reside on the same LAN as the victim, affect only non-standard configurations or obscure applications, or provide very limited access. In addition, WildFire Submissions log entries with a malware verdict are logged as Medium.
Warning-level threats that have very little impact on an organization's infrastructure. They usually require local or physical system access and may often result in victim privacy or DoS issues and information leakage. Data Filtering profile matches are logged as Low.
Suspicious events that do not pose an immediate threat, but that are reported to call attention to deeper problems that could possibly exist. URL Filtering log entries and WildFire Submissions log entries with a benign verdict are logged as Informational.
