Careers Information
Stolen laptops? Lost discs? These days Information Assurance is high on HMG’s agenda, and that is set to rise even further in the current climate.

IA is a very broad and deep subject, covering everything from looking after laptops and CDs to risk management governance at Board level through correct system design and operation to the detailed research into the vulnerabilities of specific security enforcing devices. Effective provision of IA services can only be done if the IA specialists have a firm understanding of the end-user business requirement.

The 3 key principles of IA are:
  • Confidentiality
  • Integrity
  • Availability
Within the IA Career Stream we have a range of roles that are employed in meeting these requirements. Currently 3 specialist roles have been agreed:
IA Leader
Responsible for providing expert advice on the application and development of particular IA skills, and setting the department’s strategic technical direction in the associated IA field(s). Architects and oversees the development of new capability and techniques. Will provide a level of technical innovation and take the lead in resolving particularly complex problems in the field. Acts as mentor for specialists within the IA Technical & Policy Expert role, providing training and advice as required.

IA Technical Expert
Responsible for all aspects of technical information assurance relevant to services and operations for GCHQ, HMG, wider UK government and international relationships. Can contain a heavy element of external Consultancy across all of the GCHQ IA mission's customer set. Requires a number of years experience in a technical IT/IA discipline (or relevant qualification for graduate entrants).

IA Policy Expert
Responsible for all aspects (develop, influence, maintain, interpret, advise, apply, adapt, communicate, etc) of national, international and commercial IA policies that are relevant to GCHQ, HMG, wider UK government and international relationships. Like the Technical Expert role, can contain a heavy element of external Consultancy across all of the GCHQ IA mission's customer set.

We are also in the process of defining 3 roles that will set the direction and/or assist in the delivery of IA services:
IA Delivery Leader
Responsible for providing leadership and direction to enable delivery of IA services in support of key GCHQ and HMG initiatives. Sets the strategic framework and context for the provision of all IA services. Requires a lower level of IA expertise and a higher level of people and business management skills.

IA Delivery Manager
Responsible for delivering a variety of IA services internally at GCHQ or within HMG through management of teams of technical and policy experts. Manages assignments or projects from end to end in accordance with customer requirements. Requires a lower level of IA expertise and a higher level of people and business management skills.

IA Support
Responsible for providing support to the delivery of IA services. Can be in the form of COMSEC training, technical threat assessments and technical threat awareness briefings. Requires a reasonable level of IA awareness but this can be acquired on the job. Depending on the depth of IA skills acquired, can lead onto more or less technical roles within the IACS.

To maintain and develop its status as NTA, CESG places a strong emphasis on training and development. New entrants will be provided with the opportunity to have up to 10 weeks of training in technology and information security subjects. Structured career development then takes over with opportunities available for sponsored further education, attendance at international conferences and seminars and technical mentoring.
