Container Based Issues Lock Down Password and Terminate SSL

JonathanLee · Apr 23, 2024, 12:05 AM

Hello fellow Squid Accelerator/Dynamic Cache/Web Cache Users/PfSense users

I think this might resolve any container based issues/fears if they happened to get into the cache. Ie a Docker Proxy got installed and tried to data marshal the network card inside of a freeBSD jail or something like that. Biggest fear with my cache it is a big cache now

Please let me know what you think or if it is wrong.

Here is my configuration. I wanted to share it as it might help to secure some of this.

Keep in mine I use cachemgr.cgi within Squidlight so I had to set the password and I have to also adapt the php status file to include the password and also the sqlight php file.

After that the status and gui pages work still with the new password. Only issues area that it shows up in clear text when it goes over the proxy I can see my password clear as day again that was an issue listed inside the Squid O’REILLY book also. Again this is when you view the Squid Realtime so most often users won't see that just admin.

I am amazed at the warm updates that was the original goal I was tired of slow updates over and over again for the same update on different laptops

@JonathanLee said in Container Based Issues Lock Down Password and Terminate SSL:

ssl_bump terminate all # if its not on the list kill the connection

UPDATE 4-23

ssl_bump terminate all # if its not on the list kill the connection

This will also kill windows updates over the cache I am researching why this is. I thought that would still be allowed.

Solution to use terminate connection for elevated security.

Added timeframes to secure web cache use

Add this to the top of the config
