Name and briefly describe three different kinds of recon attacks.

A reconnaissance attack isn't necessarily destructive in itself. Quite the contrary, the attacker really doesn't want to draw your attention to this type of attack. A reconnaissance attack is primarily designed to gather information and test network defenses in preparation for a future - and very destructive - network attack.

Just as a successful ping to a single IP address will tell you if that host is online or not, a ping sweep sends pings to a range of addresses to find out which ones are in use. In a similar fashion, port scans are used to find out what ports are open and can possibly be compromised. Packet sniffers can be used for much the same reason.

And just as asking questions about someone can yield information about that person, queries can help a network attacker gain information about your network. DNS queries, SQL queries, and Internet Information queries are just three query types that can be used to gather information for future attacks.

CCNP Certification / ONT Exam:
