Information sharing in the context of Critical Infrastructure is about sharing security related information. Most often it concerns Cyber Security but physical security related information may be shared as well between private, public-private and public partnerships.
It includes both information sharing to NISC and information sharing from NISC.

- Sharing Cyber Security Information 
As the threat landscape is continuously changing, the sharing of cyber security related information between organisations – in a critical sector, cross-sector, nationally and internationally – is widely perceived as an effective measure in support of managing the security challenges. Information sharing, however, is not an easy topic as it comes with many facets. The booklet aims to support the cyber security and resilience governance. Its aim is to assist public and private policy-makers, middle management, researchers, and cyber security practitioners, and to steer you away from pitfalls.
