In short, we can say that its primary work is to restrict or control the assignment of rights to the employees. It mirrors traffic that passes through a switch port or VLAN to another port for traffic analysis. DH (Diffie-Hellman) is an algorithm that is used for key exchange. Explanation: Snort is a NIDS integrated into Security Onion. HMAC uses a secret key as input to the hash function, adding authentication to integrity assurance. The default action of shutdown is recommended because the restrict option might fail if an attack is underway. 82. Verify Snort IPS.
