Ask HN: How to monitor the security of a personal VPS?
OSSEC is good for monitoring logs, system files, etc. as well as alerting (and blocking traffic if you want) when anything suspicious happens
Takes a bit of work to set up but is worth it and includes lots of basic checks by default

Passive log analysis software
It's been a long time since I tried using OSSEC but maybe that would help. It's a Host-based IDS, rather than a network based IDS like Snort. Last time I checked you could point it towards your logs and it will parse them offline similar to how Snort can read a PCAP file.

Not sure if it could be considered one but maybe OSSEC Host Intrusion Detection System might get you some.of the way can be found here

Intrusion detection software?
WAZUH (fork of OSSEC would be my first choice when it comes to Linux based HIDS (host based), and Snort or Suricata if you are looking for NIDS (network based). As well as Lynis for ensuring the setup of the host is as you intended.

Risks of hosting a website out of my house
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.

Server Hardening
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.
