Which option describes what Cisco Integrated Management Controller Network Security provides?
A.
protection against DDoS on the Cisco IMC
B.
a whilelist that specifies the servers allowed to access the Cisco IMC
C.
802.1x support, allowing the Cisco IMC to log in to a port security network
D.
user-configured ACLs to block known bad servers from accessing the Cisco IMC
Answer: A
The CIMC uses IP blocking as network security. IP blocking prevents the connection between a server or website and certain IP addresses or ranges of addresses. IP blocking effectively bans undesired connections from those computers to a website, mail server, or other Internet servers.
IP banning is commonly used to protect against denial of service (DoS) attacks. CIMC bans IP addresses by setting up an IP blocking fail count.
