Information security policies and processes 4net adhere to the ISO 27001 information security standard. The standard demands strict and detailed processes and policies to ensure data is fully protected both at rest and in transit, and 4net are committed to meeting these demands.

The Statement of Applicability is available to G-Cloud on request, this document references all of 4net’s policies and procedures including our IT policy, encryption systems and access control along with many other processes.

The SoA also details the reporting structure for adherence to ISO 27001. In brief this consists of our internal IT engineers who form part of our service desk team, reporting into the service desk manager. The service desk manager (for 4net’s information systems) reports to the Chief Technical Officer who has ultimate responsibility for 4net’s Information Systems security, support and development.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach 4net can deploy their service management tool – ESP. One element of the tool is Configuration Manager. Configuration Manager holds the audit list of all configuration items, their versions and understands their connections to each other. Configuration Manager provides real-time and historical views the assets, providing data for asset tracking, design and planning.

The Change Management process will ensure the impact of change is minimised, recorded and communicated. The process proactively identifies and handles associated risks and security impacts, thus reducing any adverse effects as a result of change. The process confirms readiness for implementation and transition into service operation
Vulnerability management type Supplier-defined controls
Vulnerability management approach 4net continually assess software and firmware across the deployed platform, both by assessment of product and security release notes and by ESP’s tool Release Manager.

Release Manager monitors firmware and software revisions at the latest release. Release Manager uses Configuration Manager’s CMDB as a source for the existing release levels, which is updated on a regular basis.

4net assesses the release and our policy is for security breaches and updates, to deploy straightaway and for all other releases to deploy if it is to resolve a known issue or following consultation with the customer.
Protective monitoring type Supplier-defined controls
Protective monitoring approach 4net can deploy ESP, a service management tool that proactively manages and monitors the platform. When an alarm is received, ESP will automatically attempt resolution by running scripts against known problems within its knowledgebase. If an automated resolution is not possible, ESP will email the 4net ServiceDesk with details of the issue.

The 4net ServiceDesk will then create a ticket, notify the customer’s service desk and assign the ticket to a 4net engineer to triage and restore. Response will be in accordance to the designated priority of the issue and the SLA.
Incident management type Supplier-defined controls
Incident management approach 4net has a documented Incident Management process which is provided with an Operational Services Manual. This will include ‘knowledge
articles’ and ‘templates’, which are updated, for common issues.

All Incidents are reported and logged via the 4net ServiceDesk. Incident logging is either automated via ESP or manually by phone, email or the customer web portal. Outside of automated Incident logging, we ask that Priority 1 and 2 tickets are phoned in and Priority 3 and 4 are either emailed and logged via the portal.

The Service Delivery Manager will provide Incident reports, RCAs and service reviews to an agreed schedule.
