3. WHAT IS OPEN SOURCE ? In production and development, open source is a philosophy, or a methodology that promotes free redistribution and access to a product's design or ideas and implementation details. open as in free open as in access open as in over time open as in not closed open as in reuse and change open as in any place and for anyone

4. OPEN SOURCE VS. CLOSED SOURCE View/Modify the source code of an application or software. Open source software is released to the development community and undergoes a secondary phase of evolution, but closed source software is developed in isolation with a small team of developers. Developer support and large community to help. Open Source is more secure and bugs and vulnerabilities are fixed often.

5. CRITERIA FOR OPEN SOURCE Source Code Availability Derived Works Free Redistribution Distribution of License Integrity of The Author's Source Code License Must Not Restrict Other Software No Discrimination Against Persons or Groups No Discrimination Against Fields of Endeavor

6. HOW OPEN SOURCE WORKS ?

7. ADVANTAGES OF OPEN SOURCE Availability of source code Source code to understand and learn from Do not have to re-invent the wheel Free as in “freedom” Does not depend on vendor Can choose additional support Can fix bugs and adapt to change in requirements as well as technology Quality and Customizability in open source is better. Costs much less than proprietary counterparts.

8. SOME DISADVANTAGES OF OPEN SOURCE Not generally straightforward to use and requires a certain learning curve to use and get accustomed. Incompatibility issue with software and hardware. (3 rd party drivers) Bad Codes, and some unqualified people who uses it. Software quality assurance process is widely not transparent No financial incentive.

12. MORE EXAMPLES- ANDROID Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Android is open source and Google releases the code under the Apache License after acquiring it from Android Inc. Most widely used mobile platform with over 7,00,000 apps in google play store, over 25 billion app downloads with 750 million devices running on Android. Android Source Code Available at : http://source.android.com/

13. MORE EXAMPLES - LINUX Linux is a computer operating system assembled under the model of free and open source software development and distribution. Originated in the GNU Project, initiated in 1983 by Richard Stallman, in the Free Software Foundation. More than 90% of today’s supercomputers use Linux. It powers around 4.8% of todays modern computers. Thousands of distros are available.

14. OPEN SOURCE OFFICE SOFTWARES Open Office : Apache OpenOffice is an open-source office productivity software suite with official website OpenOffice.org, launched in 2002 under the Apache License LibreOffice : Developed by The Document Foundation, it is licensed under the GNU Lesser General Public License (LGPL). It supports Windows, Macintosh and GNU/Linux systems. NeoOffice : Primarily designed for Mac users and is distributed under the GNU General Public License. Koffice : It is a open source office suite licensed under the LGPL. It is available for Windows, Linux, FreeBSD and Mac OS X systems.

15. LICENSE AND COPYRIGHTS There are hundreds of different licenses. Author chooses to license under a licence granting open source freedoms. Some are easy to comply with like : “You can do anything you like with this software, as long as you buy me a drink sometime if we meet”. Some licenses are more difficult to comply with : GNU GPL says that you can only use GPL code if modified/distributed code is also released under the GPL “ Copyleft ”

16. LICENSE AND COPYRIGHTS About 55% of these projects use a copyleft licence . But the 6 most common licences cover about 90% of open source projects. GNU General Public License (GPL) GNU "Lesser" General Public License (LGPL) Mozilla Public License 2.0 Eclipse Public License Apache License 2.0 BSD License MIT License

17. Software for Network Monitoring

18. Solarwinds a powerful and inexpensive network monitoring software that lets IT administrators detect, analyze, and resolve network performance problems. Solarwinds is not free software

19. Solarwinds

20. Solarwinds can help an organization’s network in terms of: Speeds troubleshooting by increases service levels and reduce downtime. Monitors and displays response time, availability, and performance of network devices. Improves operational efficiency with dashboards, alerts, and reports. Discovers network devices automatically and can be typically deployed in about an hour.

21. PRTG PRTG Network Monitor ( Paessler Router Traffic Grapher ) is a “free” network monitoring software from Paessler AG.   PRTG is free software but on a limited number of sensors. PRTG 100 is available for both personal and commercial use for free, but is limited to monitoring 100 sensors.

24. Software for Packet Sniffing

25. Packet Sniffing Packet sniffing is the method of gathering, collecting, and logging some or all packets that pass through a computer network

26. Two main parts of packet sniffer network adapter connects the sniffer to the existing network software that provides a way to log, see

27. Wireshark a free network protocol analyzer; it is a must-have software for any security professional or network administrator. This free software lets you analyze network traffic in real-time and is often the best tool for troubleshooting your network issues.
