distributed denial of service attack
Distributed denial of service (DDoS) attack seeks to overload a service,
usually web-based, by repeatedly sending requests for information or
messages many times a second. These attacks prevent legitimate users from
accessing the service. Distributed denial of service attack uses multiple PCs
to launch the attack, which increases the disruption, and attackers usually
make use of a botnet. (Cyber Security Operations Centre (CSOC))
electronic warfare
Military action that exploits electromagnetic energy to provide situational
awareness and achieve offensive and defensive effects.
(Allied Administrative Publication (AAP)-06)
firewall
A part of a computer system or network which is designed to block
unauthorised access while permitting outward communication. (COED)
global positioning system
(GPS)
An accurate worldwide navigational and surveying facility based on the
reception of signals from an array of orbiting satellites. (COED)
honeypots and honeynets
Programs that simulate one or more network services that you designate
on your computer’s ports. An attacker assumes you’re running vulnerable
services that can be used to break into the machine. A honeypot can be used
to log access attempts to those ports including the attacker’s keystrokes.
This could give you advanced warning of a more concerted attack. (SANS)
human intelligence
A category of intelligence derived from information collected and provided
by human sources. (AAP-06)
