It’s a process that touches every layer of your stack, from account passwords to network firewalls and SSL/TLS. Our security articles cover four main pillars of security: 1. **Account & Access** – lock down logins with strong passwords, two-factor auth, and secure notes. 2. **Network Protection** – shield ports with Cloud Firewall rules and VPN tunnels before traffic even hits your server. 3. **Server Hardening & Monitoring** – minimize attack surface (services, permissions, file-system tweaks) and run scheduled vulnerability scans. 4. **Encryption & Certificates** – keep data in transit private with correctly installed, auto-renewing SSL certificates. --- Security Articles 96 results This collection of articles serves as your central resource for understanding, and managing the security of your Liquid Web account, server and websites. - ## [A Liquid Web customer’s guide to vulnerability scans](https://docs.nexcess.com/hosting/security/guide-to-vulnerability-scans/) Vulnerability scans are an important part of maintaining your server’s security, especially in today’s online threat landscape.
