Network Hacking: TLS and Certificate Hygiene Notes

TLS findings need care: severity depends on who can abuse them and whether browsers actually warn. Still, hygiene tells you how mature the ops story is.

Check without theatrics

• Host/SNI mismatches on in-scope names

• Expired or soon-to-expire certs on customer-facing hosts

• Mixed content paths that quietly break HTTPS promises

Write for ops

Recommend automation for renewal and inventory—not a one-off manual swap. Link browser-visible impact when it’s real.
