VPN Access and Activity Monitoring
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.
Some difficult questions will need to be answers:
How many concurrent users can login at the same time?
Will the vpn corporate policy be relaxed to accommodate the maximum of employees?
Who gets priority access if the appliance or service cannot support everyone?
How much bandwidth a typical user use?
Do you split access time between users (i.e. each gets 2 hours)?
Number of VPN license or MFA token available
Are users allowed to use the personal computer?
If personal computers are allowed:
- What is their security posture (patches, AV update, etc)?
- Can they be trusted?
- What files or shares are employees allowed to access?
What are the alternative?

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
