Configuration and change management standard Supplier-defined controls
Configuration and change management approach We follow ITIL 3 aligned Change and Configuration processes for all changes All changes to infrastructure and systems are managed through these processes ensuring that standardised methods and procedures are followed for all. The process ensures that all changes are formally assessed, authorised and controlled to minimise any adverse service impact. Our Change Advisory Board assess and validates all Changes from a business, technical, security and delivery perspective, drawing on subject matter experts when required. A Forward Schedule of Change is maintained.
Vulnerability management type Supplier-defined controls
Vulnerability management approach We work closely with officially appointed security advisors/accreditation bodies, comply with current legislation/standards e.g. NCSC guidelines. We are registered with NCSC Cyber-security Information Sharing Partnership (CiSP), to exchange cyber threat information in real time/increase situational awareness and receive information about potential threats via suppliers e.g. Microsoft. We deploy automated tools for vulnerability monitoring. Alerts are immediately investigated by an engineer and any identified threats immediately removed from the network to eliminate the risk of potential infection. Critical patches are tested on a sand-boxed device on-receipt and deployed across the infrastructure once proven to achieve maximum cover with minimum business impact.
Protective monitoring type Supplier-defined controls
Protective monitoring approach Protective monitoring will be carried out in line with the customer's existing processes. Vysiion can provide an additional protective monitoring service if required.
