Intel Seen More

This package provides additional seen scripts for Zeek's intelligence framework. It implements the following functionalities:

udp: Sees originator and responder of UDP connections. Note: The script uses the potentially expensive event new_connection.
icmp-ping: Sees originator and responder of ICMP echo requests and replies. Note: The script uses potentially expensive events.
effective_dns: Introduces the Intel::EFFECTIVE_DOMAIN indicator type for effective domains. For example "wikipedia.org" will match "www.wikipedia.org" and other subdomains. Note: The scripts require the DomainTLD package.
conn-tcp: Introduces the Intel::CONN_TCP indicator type supporting <IP>:<Port> indicators for established TCP connections.
