How to Build a Hostile Indicators Checklist Without Relying on Profiles

A hostile indicators checklist should help trained personnel recognize behavior that deserves a closer look, not label people based on identity, ideology, appearance, or a single unusual act. The strongest checklists connect observable conduct to context, require corroboration, and tell the user what to do next. That makes the tool useful for security awareness, education, and structured review while reducing the risk of overreaction. Kensington Security Consulting develops educational tools from decades of intelligence experience, including the Kensington Hostile Indicators Checklist, to help organizations turn scattered observations into disciplined questions and responsible action.

Start With Behavior, Context, and Change

A sound checklist begins with what a person did, the setting in which it occurred, and whether the conduct represents a meaningful change or pattern. One isolated fact is rarely enough. Teams should distinguish a reportable observation from a conclusion about motive. The FBI’s behavior-based threat assessment guidance similarly emphasizes assessing concerning behavior in context rather than relying on profiles.

Useful entries describe actions in neutral language. Examples might include repeated attempts to bypass access rules, unusual collection of information outside a person’s duties, unexplained efforts to conceal activity, or a combination of grievance, preparation, and capability indicators. Each item should prompt documentation and review, not automatic guilt. This distinction is central to specialized counterintelligence and terrorism education, where personnel learn to evaluate signals without turning a checklist into a substitute for judgment.

Separate Indicators From Conclusions

An indicator is a fact that may increase concern; a conclusion is an analytic judgment reached after evaluating multiple facts and alternatives. Mixing the two invites confirmation bias. A checklist entry should capture who observed the behavior, when it occurred, what was actually seen or heard, and what other information might confirm or explain it.

A practical form can include four fields: observable behavior, context, corroboration, and disposition. The disposition may be no action, monitor, seek clarification, refer for review, or escalate through an established channel. This makes the checklist an aid to disciplined triage rather than a scoring device that produces false certainty.

Use Thresholds That Trigger Review, Not Automatic Punishment

Thresholds should define when trained review is required. They should not promise that a certain number of checked boxes predicts violence, espionage, or terrorism. Human behavior is dynamic, and threat assessment is a continuing process.

Organizations can define a low threshold for documenting ambiguous observations, a higher threshold for multidisciplinary review, and an urgent threshold for credible evidence of planning, capability, or imminent harm. The FBI’s practical threat assessment guide explains why prevention depends on gathering information, assessing it, and managing risk over time. Emergency conditions should always follow the organization’s established law-enforcement and safety procedures.

Build a Reporting and Review Workflow Around the Tool

A checklist has little value if personnel do not know where reports go or what happens after submission. Assign an owner, establish secure handling rules, identify reviewers, and specify response times. The reviewer should be able to request clarification, compare related reports, and document why a matter was closed or elevated.

Working groups are especially useful when concerns cross security, legal, human resources, operations, or education functions. Kensington’s working groups and study sessions are designed to help participants examine complex problems collaboratively instead of leaving one person to interpret every signal alone.

Train With Scenarios and Recalibrate Regularly

Scenario practice reveals whether checklist language is understandable and whether two trained users reach reasonably consistent decisions. Use realistic but fictional cases, include ambiguous facts, and require participants to explain both what raises concern and what could reduce it.

Review the checklist after exercises, incidents, changes in mission, or new threat reporting. Remove vague items, add missing context prompts, and record lessons learned. Case studies and documentaries can give teams a shared factual record for discussing how indicators emerged, which assumptions failed, and what responsible intervention might have looked like.

Frequently Asked Questions

Can a checklist predict who will commit violence?

No. A checklist can organize observations and support threat assessment, but it cannot predict an individual’s future behavior with certainty.

Should ideology appear on a hostile indicators checklist?

Ideology alone should not be treated as proof of a threat. The focus should remain on behavior, context, capability, intent, and applicable legal protections.

Who should review reports?

The right team depends on the organization, but it often includes security, legal, operational, behavioral, and law-enforcement expertise under clear governance.

How often should the checklist be updated?

Review it after exercises, incidents, material mission changes, and new authoritative guidance, with a scheduled review at least annually.
