Your Strategy
Avoid making direct changes to the source code of the old app. Protect the system with a modern security mantle: use a WAF for virtual patching and an identity proxy for MFA.Best Practices
- ▸Isolation: Run the legacy app in a separate network VLAN.
- ▸Hardening: Enforce state-of-the-art TLS 1.3 at the load balancer, even if the app only supports TLS 1.0.
- ▸Monitoring: Monitor every request for anomalies, as the app itself often does not provide adequate logs.
