International Best Practices Workshop on Insider Threat Mitigation in the Nuclear Sector

17 February 2022 - 23 February 2022 Online, Selected Audience
Workshop on autonomous and remotely operated systems: Benefits and challenges to nuclear security


Nuclear operators seek to employ personnel who can be trusted with sensitive information, critical technology, and hazardous nuclear and radioactive materials. This requires employees who are honest, dependable and mentally and physically stable. Certain social backgrounds and external influences, as well as a host of other influential factors, can create undue levels of vulnerability, altering a person’s dependability, moral character, motivations and allegiances. History has repeatedly shown how such changes have resulted in insider threats and weaknesses in nuclear safety and security, sometimes leading to serious consequences.

Past incidents have clearly demonstrated that insiders can take advantage of their access rights and knowledge of a certain facility, as well as their authority over staff, to bypass dedicated security measures. They can also threaten cyber security, safety measures, and material control and accountancy (MC&A). Insiders are likely to have the time to plan their actions; in addition, they may work with others who share their objectives. Employees may also sometimes cause harm unintentionally, particularly in the cyber realm.

States around the world have faced a number of terrorist attacks perpetrated by individuals claiming to having been inspired by, amongst others, religiously oriented groups like the Islamic State (IS) and Al Qaeda, and by right-wing anti-government militias and white supremacist groups. These attacks have led to the death of innocent civilians and shocked society by their indiscriminate violence. Often referred to as violent extremists (VEs), such individuals are often lone actors who might have been radicalised by passively consuming violent extremist material online. They tend to have few, or no, connections to radical groups or individuals in other countries before they engage in solo acts of violence. From the perspective of the nuclear sector, one of the most serious security concerns is that employees could become radicalised—or that inidividuals who have already been radicalised are hired—and subsequently use their positions of trust and authority to carry out a malicious act.

With the support of other stakeholders such as specialised law enforcement agencies, nuclear operators can take concrete actions to protect their materials and facilities from insiders, including violent extremists. For example, they can develop a comprehensive insider threat mitigation strategy that provides the foundation for the effective implementation of plans and procedures. This includes implementing specific measures for pre-employment vetting, as well as during-employment behaviour observation and aftercare. Effective insider mitigation programmes should also include measures to reduce the risk of an unwitting insider who unknowingly assists an adversary in performing a malicious act.

Countering the insider threat requires that all individuals within the nuclear organisation play their part, not simply the Security Department. This begins with the commitment of leadership. Both executive and line management must demonstrate their belief that a credible threat exists and that nuclear security is important. They must lead by example. The human resources department also plays a crucial role by creating employment policies, procedures and programmes that support a security-aware culture amongst staff.


The workshop will review credible insider threats in the nuclear sector and highlight the importance of comprehensive insider mitigation programmes. Specifically, the event will identify the motivation, intentions and capabilities of potential internal adversaries and emphasise the use of vetting programmes and other selected preventive and protective measures as best practices to reduce the risk. It will also explore the role of different stakeholders involved in identifying internal threats and will assess their current contribution to mitigate them.

The key objectives of the workshop are:

  • To review how the insider threat landscape has evolved in the last few years and to listen to the processes leading to radicalisation and violent extremism;
  • To review the process for identifying the motivation, intention and capabilities of insiders and to discuss real life examples and applicable case studies;
  • To identify and explore the role of different stakeholders involved in the identification and mitigation of insider threats with specific reference to the nuclear sector;
  • To review the key components of insider mitigation programmes, with a focus on human reliability and employee satisfaction programmes, and to highlight the importance of a robust security culture;
  • To identify methodologies and metrics for measuring the performance of the insider mitigation programme and to share practices for reporting it to senior management.

Expert speakers from the nuclear industry and other critical infrastructures will be invited to share their experiences and lessons learned from implementing security arrangements against insiders and violent extremists. Participants will be encouraged to identify immediate steps that can be taken to strengthen nuclear security programmes and mitigate insider threats in their organisations and countries.


The workshop will be open to a group of 60 participants. Applications will be accepted until 19 December 2021.

WINS is promoting gender parity and diversity in all of its events. This event will have both female and male subject matter experts. Female participants and people from all backgrounds are strongly encouraged to apply for this event.

The workshop will target security managers and other security professionals from nuclear operators and regulatory bodies as well as human resources managers, psychologists and other experts in human factors. It will also target senior officers from law enforcement agencies and representatives of international organisations. Academic experts and representatives from other industries will be invited to present their experiences and lessons learned.

This event will be conducted in collaboration with CRDF Global. CRDF Global will be responsible for the registration and selection of participants. Applications will only be accepted through the CRDF Global registration page. CRDF Global will inform applicants who have been selected.


The workshop will be conducted online on 17, 22 and 23 of February 2022. All live sessions will be organised from 10:00am to 01:15pm CET.

The workshop will be conducted in English only. It will be professionally facilitated and delivered online using Zoom or a similar platform. Pre-recorded materials will be made available to support the preparation of the workshop.

The live sessions will be recorded. The workshop materials will be available on the WINS website after the completion of the workshop.

The workshop will include expert presentations, plenary and group discussions, and a TTX.

WINS will provide participants the opportunity to interact amongst themselves and with the subject matter experts to exchange their thoughts and professional experiences on the topic. The discussions will be unclassified but subject to Chatham House rules (what was said can be reported, but not attributed).

The workshop will be designed having regard to gender parity and diversity in relation to the choice of imagery to promote the workshop, the selection of subject matter experts and their distribution among the range of topics covered in the workshop.
