VPN Access and Activity Monitoring, (Sun, Mar 15th)

Because most individuals are going to have to work remotely from home, the activity that should be scrutinized over the coming weeks would be ports associated with VPN like OpenVPN (1194) or SSL VPN (TCP/UDP 443, IPsec/IKEv2 UDP 500/4500) with their associated logs to ensure these services are accessed by the right individuals and are not abused, exploited or compromised. It will be very important the VPN service is patched and up-to-date because there will be way more scrutiny (scanning) against these services. Capturing metrics about performance and availability will be very important to ensure mission critical systems and applications can be accessed to avoid downtime.
