A governance authority posed a question:
"are external sources able to make calls to GetHost services/functions to Linux servers in our infra ie passing
thru firewall/IPS" ?
Does the question above make sense or it was mixed up with the case below:
If it makes sense, does it go thru Tcp80, Tcp443 ? Then will need IPS to detect & block it?
Any common services (python?) that uses GetHostbyName & on what Tcp ports they are listening on usually?
(if this makes sense)
