When configuring SmartEvent Initial settings, you must specify a basic topology for SmartEvent to help it calculate traffic direction for events. This setting is called Internal network(s) and you are defining your networks. You can specify one or more networks or IP addresses that are considered internal for SmartEvent. This helps SmartEvent to determine the direction of the traffic (inbound, outbound, or internal) and generate events accordingly. Reference: [SmartEvent Administration Guide]

Explanation
The Threat Prevention software components available on the Check Point Security Gateway are IPS, Anti-Bot, Anti-Virus, Threat Emulation and Threat Extraction. These components provide comprehensive protection against various types of cyber threats, such as network attacks, malware, ransomware, phishing, zero-day exploits, data leakage, and more. IPS is a network security component that detects and prevents malicious traffic based on signatures, behavioral patterns, and anomaly detection. Anti-Bot is a network security component that detects and blocks botnet communications and command-and-control servers.
Anti-Virus is a network security component that scans files for known viruses, worms, and trojans. Threat Emulation is a network security component that emulates files in a sandbox environment to detect unknown malware and prevent zero-day attacks. Threat Extraction is a network security component that removes malicious content from files and delivers clean files to users.

Explanation
Active Directory Query is an identity acquisition method that allows a Security Gateway to identify Active Directory users and computers by querying domain controllers for security event logs. The Security Gateway sends a WMI query to each domain controller and receives a WMI event when a user logs in, logs out, or unlocks their computer. The Security Gateway then maps IP addresses to user names based on these events.
Active Directory Query does not require any software installation on domain controllers or clients, but it requires certain permissions and configurations on the domain controllers Reference : https://sc1.checkpoint.com/documents/R76/CP_R76_IdentityAwareness_AdminGuide/62402.htm
