And CONNECT requests are illegal unless explicitly talking to a proxy. Passing port 443 there will only result in dropped connections and maybe logged warnings about garbage (encrypted data) arriving from a client. To intercept HTTPS you do need to be on an https_port.

Laws vary by country. At least in the US, SSL-Intercepting admins are much more likely to face civil liability than any sort of criminal charge. So no prison, just bankruptcy. With the requirement to load a public key on the machine being intercepted, generally this is only deployed in situations where the owner of the proxy also already "owns" the user machine. I'm using a commercial tool which gets around the headaches and legal issues by inspecting the HTTPS outbound data on the client, before it gets encrypted. This "agent" only works with IE/Firefox.

So no prison, just bankruptcy. IT highly depends on what will admin do with the data - if and what data will leak out. > With the requirement to load a public key on the machine being > intercepted, generally this is only deployed in situations where the > owner of the proxy also already "owns" the user machine. I still would like to warn all admins of security breach using the sslbump and legal or ethical risks of doing that. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
