Millions of self-quarantined employees are as productive as ever with extended and scaled Zoom and VPNs. However, it’s too soon to announce ‘business as usual’ without addressing the additional attack surface gained as a result. This is increasingly true in the case of combined home-work computers.
Corporate firewall and anti-phishing security controls rarely apply, home routers are ungoverned, browsers hold sensitive passwords and kids and adults alike are being targeted with phishing campaigns daily through email and sites. A possible outcome is that the VPN is transformed, by an "owned" computer, into a magical back door to the organizational network.
The most important thing to do is to test and test again - to determine and prioritize the controls required to harden the dwelling workforce environment.
