ssldump VS Suricata

I recall seeing a thread somewhere saying tcpflow would not add this capability and they point people to ssldump [1][2] and even that has some limitations.

Linux has (free) tools to improve security and detect/remove malware: Lynis,Chkrootkit,Rkhunter,ClamAV,Vuls,LMD,radare2,Yara,ntopng,maltrail,Snort,Suricata...

Monitoring & Active Measures - Exporting firewall events to an external time-series database like I describe above is good to see who is touching your firewall or accessing your web site. Using an Intrusion Detection System / Intrusion Prevention System (IDS/IPS) such as open-source Suricata, which is a free package on pfSense, and deploying file system integrity monitoring, such as the open-source Wazuh on the exposed server are also good approaches to protecting yourself.

You could try running Suricata

Active Measures - Includes (IDS/IPS) such as open-source Suricata or Snort on pfSense, and File Integrity Monitoring (FIM), such as the commercial Tripwire and dated, open-source Tripwire, or the open-source Wazuh installed on servers. These can be combined into a Security Information and Event Management (SIEM) system like the open-source solution, Security Onion. Wazuh itself has evolved into a SIEM.

Active measures may include an intrusion detection system / intrusion prevention systems (IDS/IPS) such as open-source Suricata on the firewall, and installing file system integrity monitoring, such as the open-source Wazuh on the exposed server. These are combined in one open-source solution, Security Onion
