1. OPEN SOURCE.
Good software arises when one or more very
good programmers work closely full time
together over a period of time developing,
maintaining and improving it.

2. Topics To Be Covered:-
• The open source standard requirements for software and their rationale.
• Open source intelligence (OSINT).
• The open source software and its issues related to customer.
• The open souce operating systems and their market capital.

3. Let’s Have An Idea About The
Open Source Culture

4. OPEN SOURCE AND ITS SOFTWARE.
• The term open source refers to something that can be
modified because its design is publicly accessible.
• While it is originated in the context of computer software
development,today the term “open source” designates
a set of values-what we call the open source way.
• Open source software is software whose source code is available for modification
or enhancement by anyone.

5. DIFFERENCES BETWEEN OPEN SOURCE
AND CLOSED SOURCE SOFTWARES.
OPEN SOURCE SOFTWARE. CLOSED SOURCE SOFTWARE.
• Open Source Software is a software
that is free to use and which
provides the original source code
used to create it so that advanced
users can modify it to make it work
better for them.
Closed source software the company
that developed the software owns the
software and no one may duplicate it or
distribute it without company's
permission.
• Examples:Linux,GIMP,Blender,Inkscape,
Mozilla firefox 3.0,OpenOffice.org etc.
Examples:-Microsoft Office,Adobe photoshop,
Adobe Flash CS3,Corel Office etc.

7. THE OPEN SOURCE STANDARD REQUIREMENT
FOR SOFTWORE AND THIER RATIONALE.
THE RATIONALE:
 Metcalfe’s Law: The interoperability increases geometrically with the number of
compatible participants.
 Reed’s law :The utility of a network increases exponentially due to the number of
possible subgroups that interoperability enables.
 Whichever law ultimately governs, interoperability is a positive function governing
value.

8. If interoperability is a grand goal as it relates to software, then standards are the critical
tools for achieving this goal.
Moreover,standards that permit:
• any license(free,open or closed).
• any implementation.
• any implementor .
• Will expand the universe of interoperability.
• The important question to ask is what the standard does or does not offer based on its
implicit or explicit license or technology freedoms or restrictions.

9. The Requirement:
• An "open standard" must not prohibit conforming implementations in
open source software.
No Intentional Secrets:
• The standard MUST NOT withhold any detail necessary for interoperable implementation.
Availability:
• The standard MUST be freely and publicly available.
Patents:All patents essential to implementation of the standard must be licensed.
No Agreements:
• There MUST NOT be any requirement for execution of a license agreement.

10. OPEN SOURCE INTELLIGENCE.(OSINT)
• It is an information processing discipline that involves
finding, selecting, and acquiring information from
publicly available sources
• OSINT refers to any un-classified intelligence.
• OSINT sources include business websites, social networks, videos,
forums, blogs, and news sources.

11. Open Sources of Information:
• Web-based communities and user-generated content: social-networking
sites, video sharing sites, wikis and blogs.
• Public data.
What OSINT can do?
• We are able to achieve following information of an individual or organization.
• Email address,phone numbers,OS info,IP info,software info,Geo location etc.

12. Where we can use OSINT?
• Business,Government and Individual intelligences.
Before OSINT After OSINT

13. OSINT Tools:-
Maltego:
• Maltego is an open-source intelligence and forensics application
developed by Paterva. Maltego focuses on providing a library .
Maltego, is a program that can be
used to determine the
relationships and real world links
.
Internet infrastructure such as:
Domains,DNSnames,Netblocks,
IP
addresses,Phrases,Affiliations,
Documents and files.

14. Translation services:
• Today much of the content out there is in languages other than the one you
might speak fluently.
GOOGLE TRANSLATE
• Examples:-Jigsaw,IP2Location,NewsNow,Socialmention.

15. Limitation of OSINT:
• Information overload- Information provided by OSINT Tools is huge in
amount, filtering or harvesting of data is quit time consuming.

16. THE OPEN SOURCE SOFTWARE AND ITS
ISSUED RELATED TO CUSTOMER.
• An important part of having a working open source policy and
tracking system is training.
• A very common mistake is to assume that open source code is public
domain. A public domain work is one that isn’t subject to any
copyright.

17. • First, failure to keep track and comply can complicate deals.
If you don’t keep track of your use of open-source code, you
won’t know what rights you have to your product.
• The fact that you haven’t been keeping track of open source
code and licenses and can’t account for them will come out
quickly in the diligence process.
• In extreme cases, it can sink a deal
altogether.

18. THE OPEN SOURCE SOFTWARE
AND THIER MARKET CAPITAL.
• To help industry
participants identify and
specify standards that
permit open source.
• The purpose of
open standard is to
increase the market
for a technology.

19. • Open source software projects are built and maintained
by a network of volunteer programmers.
• One of the most successful open-source products is
the GNU/Linux operating system, an open-source Unix-like
operating system, and its derivative Android, an
operating system for mobile devices.
