Information security policies and processes
We have policies for Information and security governance, Business Continuity Plans, Cultural awareness, Risk Management as well as Personal and Physical security.

These are enforced and checked using the relevant technological devices where possible (Checkpoint firewall logs, server logs, pen testing, IR Sensors, CCTV, anti tamper devices, flood sensors motion trackers) and all instances are reported to the responsible member for that area - in the main reporting directly to line managers and then CTO - and ultimately to the Managing director.

Specifically with regards to information security we ensure that all logs are automatically scanned against defined patterns stated in our IS policy.

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
We use a development operations model and standard CAB meetings for code drops and artefact alterations which must first go before the CAB board and be agreed by the CTO - all versions and artefacts are tracked through SharePoint versioning and audit controls within TFS and Visual Studio online:

Code —Code development and review, version control tools, code merging;
Build —Continuous integration tools, build status;
Test —Test and results determine performance;
Package —Artefact repository, application pre-deployment staging;
Release —Change management, release approvals, release automation;
Configure —Infrastructure configuration and management, Infrastructure as Code tools;
Monitor — Applications performance monitoring, end–user experience.
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
We put all interfacing traffic through a professional WAF

As we are an internet facing service we treat all patches as ZERO day and implement immediately - we often have to deal with regressions in those patches because of this, but can not afford for immediate patches to exploits to not be applied.

Our Cyber Essentials PLUS certification as a base line for Penetration testing Plus Sunblast IPS logs. Internal Nessus scan monthly on all products and services as well as Nessus OWASP scans against all sites.

Registered with/receive all their alerts from NHS CareCERT
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
We utilise scanning on the wire via Watchguard AI Appliances, scanning on interaction with our web services and scanning on access for all content. We have an enterprise IPS license with WatchGuard, Cloudflare, MalwareBytes, and Symantec Endpoint Protection Manager for our servers & devices.

Alerts or incidents raised go through our 24/7365 service desk covered by SLA:

Severity1 – Response within 4 hours - Used for important cases, that require an immediate fix.
Severity2 – Response within 8 hours - Used for standard issues that require investigation
Severity3 – Response within 3 days - Usually information, training, or infrastructure work
Incident management type
Supplier-defined controls
Incident management approach
All "anomalies" are reported to our 24/7 365 service desk - usually via email if picked up on scan.

We have a tiered SLA approach to these rules and react accordingly.

Users can call the same mechanism using the help desk number to report incidents.
