Security awareness
Understanding UK threat levels
The threat of international terrorism comes from a diverse range of sources and a threat could manifest itself from a lone individual or group. The terrorist threat can take a number of forms, as terrorists may use a variety of methods of attack to achieve their objectives.
While the UK has faced a variety of terrorist threats in the past, a unique combination of factors place the current threat on a scale not previously encountered.
The terrorists draw their inspiration from a global message articulated by internationally recognisable figures.
The threat from terrorism when overseas
Information on threats to personal safety arising from terrorist activities, political unrest, lawlessness, violence, natural disasters, epidemics, anti-British demonstrations and aircraft/shipping safety. It is designed to help you make informed decisions about whether or not to travel to a particular country.
The threat of espionage
The UK is a high priority espionage target and a number of countries are actively seeking UK information and material to advance their own military, technological, political and economic programmes.

Frequently asked questions
What is a security aspects letter?
The ‘secret matter’ in an invitation to tender (ITT) or contract containing DEFCON 659A must be defined to the contractor in writing. The special obligations laid upon the contractor become legally effective only when the MOD has issued a notice in writing, defining which aspects of the ITT or contract are graded at OFFICIAL-SENSITIVE or above. This is achieved by means of a security aspects letter (SAL) written by the contracting authority, or by the inclusion of a security aspects clause in the ITT or contract. A SAL provides a contractual means of ensuring that security is addressed in the work that a Contractor is undertaking. A SAL is not required if the Contractor will not be exposed to any classified material graded above OFFICIAL. In such cases the Contractor must still be informed of their security obligations via DEF CONS included in the contract.
The contractor is required to confirm in writing that he understands and will implement the terms of the SAL or clause. The SAL is the legal instrument under which a UK contractor may be prosecuted under the Official Secrets Act. The SAL must therefore be issued to the contractor with the ITT or contract document. DE&S PSyA’s office must be informed in advance if this is not possible.
Do I have a designated field adviser?
In most cases, DE&S PSyA assurance advisors are assigned by region These regions are: Scotland; England (North); England (East); England (West); England (South East) and London; England (South West) and Wales; and Hampshire. For details of your assurance advisor please contact the Security Advice Centre.
What are the timescales involved for hand carriages and transportation plans?
The required notice periods for hand carriages are:
- EU/RoW (exc Australia/US) - 2 working days
- US/Australia - 5 working days.
For transportation plans the required notice periods are:
- within UK - 3 working days notice
- EU (except Italy) - 5 days
- US/Italy/Australia/rest of world - 10 days
Please note that due to current resource issues we may not be able to approve ‘emergency requests’ with shorter lead times.

How does my company gain a Facility Security Clearance (FSC)?
Facility Security Clearance (FSC) formerly known as ‘List X’ refers to contractors or subcontractors which have been formally assessed by the relevant Government authority and reached the required standard as defined in GoVS 007 – Security to hold, process or manufacture materiel at SECRET (foreign CONFIDENTIAL) or above on the company premises. FSC is not available on request, it must be sponsored by a contracting authority (CA).
The CA can be:
- a Ministry of Defence entity: This is extensively, but not invariably, in the form of a project team (PT).
- another government department: A number of UK Government departments, may also award a facility FSC status.
- an existing FSC holding company: An enterprise with an existing government contract may act as a contracting authority to one or more third-party subcontractors who may inherit the responsibility to hold classified assets. Any move to appoint a subcontractor must be approved by the original contracting authority.
- NATO: Where a contract requires a UK enterprise to hold NATO CONFIDENTIAL (or above) information at their facility, the contracting authority will require assurance from DE&S PSyA’s office that the facility is suitable for FSC status.
- overseas governments and their contractors. In the event that an overseas contracting authority require a UK enterprise to be awarded FSC, the UK government may complete this on their behalf Key requirements for FSC status:
- a contract at SECRET (foreign CONFIDENTIAL) or above
- a requirement either for the work to be done on the contractor’s premises or for classified information to be held on site
Who is my contact for IT accreditation?
