Techopedia Explains Active Attack

An active attack is what is commonly thought of when referring to "hacking." In an active attack, the attacker attempts to alter or control data and/or the hardware it resides on. This is in contrast to a passive attack, in which the intruder may listen in on communications or monitor other aspects of the network or its devices.

Types of active attacks include:

  • Denial of service (DoS)
  • Distributed Denial of Service (DDoS)
