Why identifying potential targets and the likelihood of attacks matters in IED threat assessments

The Crucial Question in CIED Threat Assessments: Who Might Be Targeted and How Likely Is an Attack?

Threats involving improvised explosive devices aren’t random. They’re shaped by who could be harmed, where it would hurt most, and how likely an attack feels in a given space. When security professionals talk about a threat landscape, this is the cornerstone: identifying potential targets and weighing the odds of an attack. If you can map those two things well, you’re already steps ahead in preventing harm.

Why this factor sits at the top

Let me explain with a simple idea. Imagine you’re planning security for a big event, a transit hub, or a public square. If you know which venues or groups are most likely to attract an attack, you can focus surveillance, patrols, and readiness where it matters most. That’s the heart of a solid threat assessment: it guides where to put eyes, cameras, canine units, and quick-response teams so resources aren’t spread thin.

This approach isn’t about guessing; it’s about patterns. History leaves clues—where past IED incidents happened, what kinds of campaigns unfolded, and which soft targets drew attention. Intelligence from multiple sources, including on-the-ground observations and publicly available information, helps piece together risky scenarios. When you understand the targets and the likelihood, you can create layered defenses that scale with risk.

What goes into estimating targets and likelihood

Think of this as a detective brief, not a single alarm bell. It blends data, judgment, and a realistic feel for how people move through space. Here are the main ingredients:

• Patterns of activity: Some places draw bigger crowds, others have critical functions that, if disrupted, would create cascading effects. Stadiums, transit stations, government facilities, and large commercial venues often generate higher risk footprints.

• Historical data: Past incidents aren’t destiny, but they’re informative. They show common threads—types of targets, timing patterns, and attack methods. Sift through where and when similar events occurred to spot predictable rhythms.

• Specific intelligence: When available, trusted intelligence signals sharpen the view. This isn’t about sensational headlines; it’s about credible, actionable inputs that help you weigh risk for particular locations or events.

• Environmental context: The layout of a site, visibility, entry points, crowd density, and alternative routes all influence how tempting a target feels and how feasible a response must be.

• Threat actors and capabilities: The messages, tools, and tactics associated with potential attackers affect likelihood estimates. A group with limited resources but high motivation might target soft, accessible venues; well-equipped operators might threaten more fortified spaces.

• External indicators: seasonal patterns, large gatherings, or high-profile visits can shift risk levels. A lot of risk assessment is about recognizing when a normal day suddenly carries additional weight.

The practical payoff

When you can pinpoint likely targets and estimate attack probability, you can tailor defenses with precision. A few practical outcomes:

• Prioritized surveillance: Focus patrols, cameras, and access control on places that show elevated risk.

• Targeted hardening: Improve physical barriers, bag screening, vehicle controls, and site-specific emergency plans where it’s most needed.

• Rapid response readiness: Train responders to recognize early warning signs most likely to appear in high-risk environments.

• Resource efficiency: Put limited budgets where they’ll reduce risk the most, instead of spreading effort evenly across many sites.

The other factors aren’t useless, but they don’t drive the immediate threat picture as directly

You’ll hear about a few other important considerations in security planning, but they don’t shift the threat landscape as aggressively as knowing the targets and their likelihood. For example:

• Cost of response measures: It matters for budgeting and sustainability, but it doesn’t change the underlying risk in the same way as altering where and how you expect an attack to occur.

• Time for training: Training is essential for capability, but it’s more about readiness than redefining what the threat looks like in a given place.

• Public perception: Community confidence matters for cooperation and support. Yet perception doesn’t rewrite the concrete risk posed by IEDs in a particular venue.

• Operational constraints: Weather, staffing, and maintenance influence operations, but the core threat assessment still hinges on targets and likelihood first.

How the pieces fit together in real life

Let me offer a small picture of how teams actually work this. Think of a fusion of data streams, a touch of strategic thinking, and a healthy respect for uncertainty:

• Data gathering: Security teams collect information from multiple angles—observations from security staff, incident archives, venue layouts, traffic patterns, and publicly available data that’s relevant to risk.

• Scenario crafting: Analysts sketch plausible attack scenarios focused on the most likely targets. They don’t exaggerate risk; they position it in a way that’s actionable.

• Prioritization: Each scenario gets a score based on how likely it is and how severe the impact would be. The highest-scoring scenarios become the top priorities for protective measures.

• Actionable planning: Based on those priorities, teams decide where to bolster screening, how to tune access controls, and where to boost post-incident response capabilities.

• Continuous feedback: As new information comes in (or as conditions on the ground change), risk scores are updated. It’s a living process, not a one-off checklist.

A few real-world touches to keep in mind

• Context matters: A crowded festival and a quiet office complex aren’t the same risk profile, even if both are high-value targets. Site-specific factors matter deeply.

• Flexibility is a strength: Risk isn’t static. A sudden parade, a major sports event, or a political gathering can shift risk overnight. Plans should bend without breaking.

• Collaboration helps: Local law enforcement, public safety partners, venue operators, and even businesses in the area all contribute something useful. Sharing insights helps sharpen what’s at stake and where to act.

• Communication matters: When the public understands security measures are data-driven and focused on safety, trust grows. Clear, calm communication supports effective security without causing panic.

Nuances that make the topic feel real

This isn’t a dry checklist. It’s about reading spaces the way a good host reads a party. You notice who’s moving through a venue, where lines form, how crowds split, and where blind spots hide. You think about how an attacker might exploit that environment and how you would notice something off before it becomes a problem. It’s part science, part attention to people, and a dash of street-smarts.

A few practical tips for learners

• Start with geography: Get comfortable with the layout of common sites—entries, exits, choke points, and control zones. A rough map helps you see where risk concentrates.

• Read patterns, not headlines: Focus on patterns of past events and typical threat actor behavior rather than sensational stories. The repeatable parts are the learning gold.

• Use real-world analogies: Think of threat assessment like planning a major event. You’d want to know who will be there, when the crowd peaks, and where help is closest. The same logic scales to security planning.

• Stay curious about tools: GIS dashboards, OSINT sources, and collaboration platforms for public safety partners can provide valuable lenses on risk. You don’t need to become a data scientist, but knowing what’s possible helps you reason smarter.

A concise takeaway

When creating a threat assessment for IEDs, the most crucial factor is identifying potential targets and judging the likelihood of attacks. This focus maps the risk landscape in a way that makes protective measures effective and efficient. Other factors—like cost, training time, or how the public feels—are important for broader operations, but they don’t redefine where danger is most likely to appear in the near term.

If you’re exploring this field, remember: the goal isn’t to predict every move with perfect precision. It’s to know enough to shield people and spaces from harm. To do that, you’ve got to start with the where and the how likely. Everything else—the resources, the training, the public trust—falls into place once you’ve got that footing.

In the end, good threat assessment is a careful balance of data, judgment, and practical action. It’s about turning complex information into clear priorities that keep communities safe. And that, more than anything, is what makes the work meaningful.
