Intelligence Cycle

Now, let’s delve into the Intelligence Cycle. This structured method guides the collection and processing of information, ensuring a thorough grasp of the OSINT process. For effective investigations, it’s crucial to follow each step of this cycle.

Stages of the Intelligence Cycle

The Intelligence Cycle is roughly divided into five stages:

Preparation. In this initial stage, investigators assess the needs and requirements of the request. There could be setting clear goals and finding the most relevant data sources.
Collection. Once ready, you should gather data from the most relevant sources.
Processing. After getting all the information, you need to organize or collate it.
Analysis and Production. You should analyze the data to make sense of it (e.g., determining patterns or establishing a timeline). The result of this stage is creating a complete report with all the answers to the intelligence questions.
Dissemination. The results of the entire intelligence gathering can be presented to the stakeholders in written reports, timelines, recommendations, etc.

Each stage is vital if your goal is to collect complete information about people or events.

OSINT Gathering Techniques

There are three key ways to collect data using OSINT:

Passive Collection

In the passive collection, the key is subtly gathering information without direct contact with the target’s system or network. This approach makes use of what’s readily available in the public domain. It’s akin to being a detective who relies solely on public information – browsing websites, diving into online articles and reports, examining public records, or scrolling through social media posts. This method is notably discreet and carries a minimal risk of detection, as it completely avoids direct engagement with the target’s systems. Typically, it is the initial phase in Open Source Intelligence (OSINT), providing critical details before moving on to more interactive methods.

Semi-Passive Collection

Semi-passive collection is more interactive than passive collection yet avoids direct contact with the target, acting as a midpoint between passive and active methods. It employs third-party tools for tasks like DNS queries, ping sweeps, and searching cached information online, ensuring no direct traffic reaches the target’s network. This method is slightly riskier in detection than passive collection but is less noticeable than active collection. It’s ideal when more information is needed than passive collection can provide, but without alerting the target.

Active Collection

Active collection is the most direct and assertive intelligence-gathering method involving hands-on interactions with the target’s systems or networks. It includes techniques like port scanning, vulnerability scanning, network mapping, and, at times, social engineering. This approach, which sends traffic or queries directly to the target, has the highest detection risk and is seen as quite aggressive. It’s typically chosen when in-depth, specific information is required and the risk of detection is deemed manageable.

Each method varies in how much it interacts with the target system and its likelihood of being noticed. Their range is from the discreet and unobtrusive passive collection to the more direct and assertive active techniques.
