There are four primary classes of attacks.
Reconnaissance
Reconnaissance is the unauthorized discovery and mapping of systems, services, or vulnerabilities. It is also known as information gathering and, in most cases, it precedes another type of attack. Reconnaissance is similar to a thief casing a neighborhood for vulnerable homes to break into, such as an unoccupied residence, easy-to-open doors, or open windows.
Reconnaissance attacks can consist of the following:
-Internet information queries
-Ping sweeps
-Port scans
-Packet sniffers
Access
System access is the ability for an intruder to gain access to a device for which the intruder does not have an account or a password. Entering or accessing systems usually involves running a hack, script, or tool that exploits a known vulnerability of the system or application being attacked.
Access attacks can consist of the following:
-Password Attacks
-Trust Exploitation
-Port Redirection
-Man-in-the-Middle Attack
