ports are showing open on online scanning tool
- Jan 20, 2025
Hello Team,
We have raised F5 case for this issue and F5 Internal team have found few logs and few TCP half-open (SYN cookie) vector which might be causing this issue which are related to AFM module. To isolate the issue internal has suggested to upgrade the tenant to the latest 17.1.1.4 (stability release) and F5OS to at least 1.5.2. and After upgrading the tenant to version 17.1.1.4 and F5OS to version 1.5.2, the issue has been resolved.
If ports are showing as open in an online scanning tool, it typically means that the system you're scanning (whether it's a server, network, or device) is accepting incoming connections on those ports. This could indicate potential security risks or might be necessary depending on the services you're running on the system. Here's how to handle this situation:
Steps to Consider:
- Identify Open Ports and Services:
- Review the ports that are open. Commonly open ports include 80 (HTTP), 443 (HTTPS), 22 (SSH), 21 (FTP), etc.
