The Wiv 2017 lists all the powers of the AIVD. These include observing and following people, the use of agents and monitoring and tapping any form of telecommunications.
Special investigatory powers, also known as "special intelligence resources", may be used only when strictly necessary for the AIVD to carry out its the duties. Special powers may not be used for two of those tasks: security screenings and safeguarding vital sectors.
Moreover, no action likely to seriously infringe personal privacy may be taken by the AIVD without the express prior permission of the minister responsible, as well as a binding verdict of an independent review board.
