LIAG - Land Information Assurance Group

Welcome to the homepage for the Land Information Assurance Group (LIAG).

LIAG was formed in 1999 so that the Army could recruit personnel from with Information Assurance (IA) skill sets gained in industry into the Territorial Army.

It is part of the Specialist Group Royal Signals (SGRS) and provides IA expertise to Army, RAF and Navy units at various locations including in the UK and worldwide: Iraq, Afghanistan, Kosovo, Germany, USA, Canada, Cyprus, Gibraltar, Ascension and the Falkland Islands, Kenya and Brunei.

Its administrative headquarters are located at Corsham, Wiltshire, but, when not on task, its officers meet for military training at various locations around the UK each year.

LIAG is a multi-cap-badged unit and currently has members who have served with the Royal Navy; Army units: Royal Artillery, Military Intelligence and Infantry Units and the Royal Air Force.

It also has members who work for the following organisations: Logica, CESG, Symantec, Oracle, Accenture, Fujitsu and Deutsche Bank. LIAG’s Commanding Officer oversees 50 personnel who are appointed as Staff Officers (Lt Colonels, Majors and Captains).

LIAG forms teams to perform specific tasks; the composition of each team depends on the size and nature of the task and they vary in size from one person to up to a dozen.

All have a Team Leader as well as personnel with the appropriate skills for that particular task:

  • Penetration testing
  • Web Application Testing
  • Database Security Testing
  • Vulnerability Assessment
  • Network Traffic Analysis
  • Computer Forensics
  • Compliance Checking
  • Incident Handling
  • Firewall Testing
  • Wireless Network Scanning
  • Intrusion Detection


LIAG holds social events each year: an Annual Mess Dinner and a Partners’ Dinner. There is also emphasis on adventurous training: mountaineering, scuba diving, sailing, skiing and parachuting.


Candidates who join LIAG from civilian life or from the other services become commissioned officers in the Royal Corps of Signals.

Candidates who hold the Queen’s commission, and are serving as regulars or reservists in the Army, will maintain their current cap badge.

We are interested in hearing from applicants who:

  • Have at least 5 years professional IA experience;
  • Hold a professional IA qualification;
  • Are prepared to serve at least 19 days per year;
  • Are ready for the responsibility of becoming a commissioned officer in the Territorial Army;
  • Are willing to undergo Her Majesty’s Government Security Clearance;
  • Are medically and physically fit.

Selection Process
If selected to join, you will be asked to attend one of our bi-annual weekend Initial Selection Boards (ISB) which comprise:
  • A five minute candidate presentation on an IA subject;Fitness test;
  • A Command Task: a team building group task;
  • A Technical Test
  • An interview by the Selection Board

Upon passing the ISB, there are two routes: candidates who already hold the Queen’s commission will join the unit shortly afterwards; candidates who are civilians or are serving as or who have served as non-commissioned officers, will attend an Army Officer Selection Board at Westbury, Wiltshire.

This board is run over a weekend and consists of a medical examination and a series of mental and physical tests, to assess your suitability to become an Army Officer.

If successful, you will then undergo officer training at the Royal Military College, Sandhurst.
