Change Control Notice


00016_20170917 to 00025_20191127 HSCN Compliance CR Form


Change Reference:  – 0021 20191127

Title:  – HSCN Obligations -Technical and Security Obligations

Change to:- Obligations Framework 4.3.3 – SP08

Dialogue:  Removal of CAS-T reference. The obligation will now read as follows.

‘The HSCN Supplier shall make their current Statement of Residual Risk available on request to HSCN Consumers or potential HSCN Consumers (under non-disclosure terms where necessary).’

NCSC have stated that CAS(T) is no longer in use. Whilst a new security standard is being established by NCSC, we have established a position where previous CAS(T) requirements are now covered by ISO27001, Annual ITHC and BCDR plans. A statement has already gone to CN-SPs so they are aware of the current situation regarding re-certification.

Change reason – To meet a regulatory requirement.

Change Level – Major. 

Comments due back on 27th December 2019. No comment is assumed to be acceptance.
