As a security-conscious individual, hosting various services can pose risks to your home lab’s integrity. Malicious apps can compromise your systems, especially when IoT devices are involved. To mitigate these threats, consider implementing the following measures:
1. **Configure VLANs**: Isolate vulnerable devices and services by separating them into virtual networks using managed switches or firewalls. This reduces the attack surface for smart home gadgets and IoT gizmos.
2. **Self-host a firewall OS**: Leverage customizable firewalls like OPNsense or pfSense to arm your systems with advanced security features, including traffic rules, IDS/IPS provisions, and VLAN support.
3. **Use an SSO server for logins**: Implement Single Sign-On (SSO) servers like Authentik to enforce login screens, track login attempts, and create blocking policies to prevent unauthorized access.
4. **Deploy unprivileged containers**: Reduce the attack surface by using unprivileged containers, which limit root-level access and remove certain security rules. This provides better isolation and security for containerized apps.
5. **Run frequent vulnerability scans**: Regularly use tools like Kali Linux’s vulnerability detection and network scanning tools to identify potential threats and patch vulnerabilities in your home lab’s systems.
