Webinar: Achieving list X security clearance: practical steps for your business. January 28th 12 noon GMT. Book your space on this free webinar in association with NDI.
If you are a commercial company seeking to hold government information with a security classification of SECRET or above on your own premises you’ll need ‘List X’ accreditation. This article will give you a very brief introduction to List X, with useful links and points of contact that will help you in the process.
Update May 2019: This post was originally published in April 2013. If you are looking for List X guidance you will find our post ‘ How to prepare your company for achieving List X ‘ of help. You might also visit our List X services page.
What is List X?
The term ‘List X’ is the UK equivalent to Facility Security Clearance (FSC) used in the rest of the world. The term refers to contractors or subcontractors that have been placed on the List X database because they are carrying out work on their own premises that bears a UK Government classification of SECRET or above.
Sponsorship for List X
Companies cannot ‘apply’ for List X status; they must be ‘sponsored’ by a Contracting Authority (CA) that intends passing them classified information. The CA can be:
- A UK government body;
- An existing List X company;
- Overseas government or defence contractors;
The CA will detail the security aspects of the List X requirement e.g. what classified information is to be held and why.
Who Manages List X?
As the Ministry of Defence (MoD) is the CA for the majority (85%) of List X sites, the whole process is managed by the MoD Defence Equipment & Support (DE&S) Principal Security Advisor (PSyA) based at Abbey Wood, Bristol. The PSyA maintains the database of approved List X sites and also a restricted access website for List X companies. For details of how to get access, phone the PSyA on 0306 79 34378.
List X Security Requirements
The process of obtaining List X is not just about an assessment of the physical controls in place at the premises where the classified information is to be held. It encompasses the whole security culture of an organisation including risk management, personnel security and security roles and responsibilities. For example, it is mandated that List X companies have a Board Level representative that accepts responsibility for maintaining the requirements of List X and informing the CA if any changes in the company are likely to impact on their List X status such as change in company ownership.
It is worth noting that the List X assessment does not cover the accreditation of IT systems. Accreditation of IT systems should be initiated with the CA’s accreditation authority (Defence Assurance & Information Security for MoD).
The Security Controller
Another mandated role for List X companies is the Security Controller. Specific duties include:
* Interpreting, implementing and monitoring compliance with List X security controls;
* Maintaining a relationship with the CA and/or MoD PSyA;
* Preparing and implementing company security instructions, Risk Management and Accreditation Document Sets (RMADS) and Security Operating Procedures (SyOPs);
* Education and awareness training;
* Incident management;
* Inform CA and MoD PSyA on changes to the List X requirement;
* Controlling visitors within the ‘need-to-know’ rule.
The Defence Industry Security Association (DISA) provide a variety of courses relevant to those working in the List X/Defence arena. Full details of these courses and of how to join DISA are shown on their website .
The Security Advisor & List X Assessment
The CA or MoD PSyA will appoint a Security Advisor who will be responsible for advising on the List X security requirements and inspecting the premises on an annual basis to ensure compliance. A List X Assessment, Checklist and Guidelines document is usually sent to the List X company at the start of the process and then annually. This document is in the form of a comprehensive questionnaire that captures the information necessary for approval for sites to handle, store, process or manufacture classified assets. It covers the Mandated Requirements (MR) listed in the Security Policy Framework and at the last count was nearly 50 pages long and takes considerable effort to complete.
