Firewalls and VPNs have become the attackers' front door

Vulnerabilities in edge devices such as firewalls, VPN gateways and load balancers are exploited within days of disclosure. Patch faster and monitor the devices themselves.

Firewall และ VPN กลายเป็นประตูหน้าของผู้โจมตี

The devices meant to protect you are now prime targets: always internet-facing, highly privileged and rarely covered by EDR. The gap between disclosure and mass exploitation has shrunk to days.

How to defend

  • Track security advisories for every vendor you use and set a 72-hour patch SLA for edge devices
  • Keep management interfaces off the internet
  • Send device logs to the SOC and watch for configuration changes
  • Plan the move from VPN to ZTNA
