1. Open Source Intelligence (OSINT)
Introduction to OSINT

2. What is OSINT?
OSINT: Open Source Intelligence; publicly available information. i.e., information that any member of the public could lawfully obtain by request or observation, as well as other unclassified information that has limited public distribution or access.
OSINT represents a constant threat to any organization or mission, and can account for up to 80% of actionable intelligence, which is generally not protected and not classified.
In most cases, it’s legal to obtain information in this way. This means that despite the high potential for harm, this critical information may be obtained at little or no risk to the intruder.

3. Definitions:
Open Source Data (OSD): the raw print, broadcast or information in any other form from a primary source. This can include photographs, tape recordings, satellite imagery, personal letters, online postings, etc.
Open Source Information (OSIF): Generic information generally intended for wide dissemination that combines multiple pieces of data using some level of validation. Examples include books, newspapers and news reports.
Validated Open Source Intelligence (OSINT-V): Information to which a high degree of certainty can be attributed. This includes two categories:
Information which comes from an established reliable source and/or can be validated by comparing to other data
Information which can be established as valid in its native format. i.e., news reports showing a state leader’s speech. This, of course, must consider the possibility of manipulation or forgery.

6. What is the value of OSINT?
OSINT has incredible value, both positive and negative to the originator or dedicated recipient of the information:
Journalists and researchers use OSINT to generate a story or obtain greater information on a subject. The US Library of Congress collects vast amounts of this type of data.
OSINT gives context to classified information. Generally, only select information meets the criteria for classification, with unclassified sources of information filling the gaps.
OSINT gives adversarial forces a starting point and additional resources necessary to leverage further attacks or exploitation.
OSINT reveals the intent of friendly or adversarial forces.
OSINT reveals current status, capabilities or other contemporary information.

10. OSINT The Internet
In the modern context, it’s tempting to think of OSINT as “the Internet”. While the advent of the internet has brought new opportunities to analysts and adversaries alike, OSINT has been a problem for the intelligence community for years before the advent of the modern Internet. Examples of resources that are of value to an adversary and predate the internet are:
Job announcements
Public records, like building permits
Personal records, like credit reports
News and periodicals, like press releases, radio, television, etc

11. iChanges
The Internet, and related technologies have, however, added to the already immense quantity of critical information that may be obtained by the public. For example:
Chatrooms, forums, file sharing
Company information in whois, online filings, etc
Webpages, blogs
Online news

12. Why create such information?
Generating information is the natural result of doing business. Much of the information that may be beneficial to an adversary is created for a legitimate purpose, such as business filings or press releases.
The important thing to consider is how this information can provide clues to identify targets, activities, real-time operations and more. When it’s necessary to create and share information, only the information that’s necessary to be shared should be included, and even that must be evaluated for its potential impact.
I’m online, therefore I am.

13. See for yourself Consider how easy it is to find information
about yourself. If you were an adversary,
perhaps a business competitor, burglar, foreign
military, or something else entirely, what could
you learn from your physical and online presence?
Personal:
Search white pages
Search social networks:
Search for your address in Google
Type in your address into Google Maps, and zoom in to street view
Search in your refuse bins- what are you throwing away?
What are you saying in chat rooms or forums?
Business:
Check your press releases and job listings. Have you listed your network security equipment in job descriptions?
Search refuse bins for sensitive memos, employee directories, etc
What is revealed on your company webpage?
