what is icmp in information security?

The ICMP protocol mainly uses a deterministic algorithm to determine whether or not data has reached its intended destination on time. A common example of ICMP usage on a network device is the router. The ICMP protocol is vital for error reporting, tests, and distributed denial-of-service attack campaigns.

The codes for many of these ICMP types are built into this type.

Is IP dependent on ICMP?

Error and control messages cannot be sent over IP due to its inbuilt lack of communication mechanisms. This is done by using the Internet Control Message Protocol (ICMP). Among the basic protocols used by devices such as routers, it is used for sending error messages and information about the operation of the device.
