I am studyng Security Fundamentals on Networks and as a part of an excercise I have the following question:
Which of the following statements are true? (Select all that apply)
a.- An IDS deals with malicious traffic that the firewall missed.
b.- An IPS is on the boundary of the trusted inside and the untrusted outside.
c.- A network-based firewall protects hosts from malicious traffic originating on their same network.
d.- An IPS protects hosts from malicious traffic originating on their same network.
What could it be the answers?, According to me b and c would be the answers because an IPS protects the original traffic that pass throug, b because it is in the boundary but I have a doubdt with option a becuase and IDS as I know makes a copy of the traffic just to analize it, what do you think?
