- OSINT tools, and
- Finally, the OSINT courses.
So, keep reading, and let’s begin! Already a seasoned OSINT’er? hopefully, you may just pick up a few new hints.
What Is Open Source Intelligence?
OSINT stands for “open-source intelligence,” which refers to data and information legally gathered from free published available sources, usually the OSINT websites. Or in simple terms, it is data and information readily available to the public, and there is no limitation on what can be found on google or the surface web.
Similarly, OSNIT is insights collected from analyzing public data sources like TV and radio broadcasts, OSINT websites, or social media platforms. Furthermore, the data retrieved can be in the form of text, images, audio formats, webinars, and video footage.
Information is considered open source when it meets any of the following criteria:
- Available publicly on request, e.g., census data
- Available publicly on purchases or subscription
- Can be obtained easily by visiting places open to the public
- Broadcasted or published in public to an audience
- Made available at a public meeting
Now that we know the basics of OSINT let’s dive into how open-source intelligence is used.
How Is Open Source Intelligence Used?
Well, OSINT cyber security experts use open-source intelligence for two crucial reasons:
1. Penetration Testing and Ethical Hacking
OSINT analysts or cyber security experts use penetration testing. This helps them discover possible security vulnerabilities on a network, computer system, or web application.
In fact, the commonly uncovered weaknesses by the cyber security experts include:
- Data leaks that accidentally reveal confidential information to the public
- Exposed assets such as devices names, IP addresses, and networks
- Unpatched software, e.g., websites using old versions of CMS products
- Open ports and unsecured devices connected to the internet
2. Determining External Threats
With much information available on OSINT websites, hackers can easily attack their targets. Therefore, open-source intelligence helps cyber security experts to address the cyber-attacks, thus dealing with these threats. OSINT helps identify current cyber threats and prevent attackers from attacking a network or an organization.
Identifying and comparing multiple data points is essential to ensuring advanced security. This is simply because it helps analysts vindicate a threat before it becomes an attack. Furthermore, security experts search deeper internet layers to determine external threats.
For instance, open-source intelligence analysts may access the deep and dark web. This helps to collect and analyze intelligence used for data leaks by hackers. As a result, it improves analysts’ potential to enhance security against potential future attacks.
Keep in mind that OSINT is important in optimizing OPSEC. This is a process of determining friendly actions that may be convenient to identify a potential attacker. This is a viable process provided they are analyzed appropriately.
What types of osint Techniques are there?
First, what is the OSINT technique?
For starters, it is important to develop a strategy and have a framework that is all-set for using open source intelligence. It is necessary because the volume of information available in open sources is quite overwhelming. The fact is, you will encounter tons of information that might drive you away from your goal. Therefore, it is recommended that you know what you want to achieve and put focus precisely to attain the set tasks.
For instance, if your goal is to identify and improve vulnerabilities in your network, that’s where you should specifically focus all your energy. In addition, it is important to identify a set of tools and techniques for gathering and analyzing open-source intelligence.
To meet their organizational needs, OSINT cyber security analysts need to adopt suitable techniques. And So, the Open Web Application Security Project (OWASP) shows Five OSINT techniques to use:
- Source Identification-Identify where to gather data regarding a specific task.
- Harvesting- Collect information relevant to your search from the source identified.
- Data Processing- Process andextract relevant details from the identified source.
- Analysis- Contrast the processed data with multiple sources.
- Reporting- Design a report on your findings.
OSINT techniques can be classified into two categories: Passive collection and Active collection.
a. Passive collection
This technique often involves collecting information about a specific network or device without necessarily engaging with the system. OSINT cyber security experts rely on third-party information using passive collection tools such as Wireshark, which analyzes traffic in a network in real-time for Mac, Unix, Linux, and Windows systems. Passive collection tools piece together the different OSINT online data points to locate and map patterns on a behavior of a network.
b. Active collection
This technique engages directly with the target system giving timely and more accurate information. OSINT cyber security analysts use active recon tools such as Nmap, which is an OSINT online network discovery tool that provides a highly detailed view of a network’s security.
