Is it feasible to disable port 80?
Applies to
- ONTAP 9
- AFF/FAS/ASA
Answer
- In ONTAP 9 the web services via HTTP(80) are disabled by default.
- Use the (privilege: advanced) "system services web modify -http-enabled false" command to disable HTTP for webservices on systems upgraded from ONTAP versions where HTTP was not disabled by default.
- Alternatively, you can configure firewall policies or LIF service policies to block access to port 80.
