IT Health Check_

As CREST-approved assessors, we can carry out your IT Health Check as part of your PSN compliance submission and assist with Code of Connection (CoCo) documentation.

What is an IT Health Check?

crest-colorAn IT Health Check provides assurance that your organisation’s external systems are protected from unauthorised access or change, and do not provide an unauthorised entry point into systems that consume Public Services Network (PSN) services.

Internal systems should also be tested to provide assurance that no significant weaknesses exist on network infrastructure or individual systems that could allow one internal device to intentionally or unintentionally impact on the security of another.

Why use 2-sec for IT Health Checks?

How to gain PSN Compliance

In order to gain a Public Services Network (PSN) compliance certificate, organisations must:

Complete a Code of Connection (CoCo)

The PSN Code of Connection (CoCo) document is the application form you need to connect to the PSN. It gives HMG certain information about your infrastructure and describes the information assurance requirements that you must be able to meet.

Provide a network diagram

This must describe the infrastructure you are planning to connect to the PSN, including third party connections, wireless networks and so forth.

Provide an IT Health Check (ITHC) report

The information in your CoCo document and network diagram must be independently verified by an ITHC provider, such as 2-sec, and subject to appropriate levels of testing.

Update contact details

Important roles within your organisation must be documented, so that any incident can be dealt with swiftly.

Submit application documents

The PSN team will review and validate your application.This typically happens within 4 weeks, and a PSN Compliance Certificate issued.
