2 Objectives Understand the Open Source License The Pros and Cons of using Open Source Understanding of Free Software Gain Knowledge of Deploying and Using Spiceworks Network Management Tool and Free Firewalls

3 Introduction to Open Source What is Open Source Open Source License Free Software Defined What is a BSD License What is a GNU License What is a MIT License

4 What is Open Source? Open source describes a broad general type of software license that makes source code available to the general public with relaxed or non-existent copyright restrictions

5 Open Source Projects are Developed BY: Hobbyists Software Companies People all over the world

6 Where are we? What is Open Source? Open Source Licenses Pros of Open Source Software Cons of Open Source Software Scenarios

7 Open Source Initiative is a CA. 501( c ) 3 corporation they are the stewards of the Open Source Definition (OSD) and the community-recognized body for reviewing and approving licenses as OSD-Conformant. The Complete Open Source Definition can be found at: Generally, open source refers to a program in which the source code is available to the general public for use and/or modification from its original design free of charge, i.e., open. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. Open Source License are License that comply with the Open Source Definition found at the Open Source Initiative Web Site

8 The Free Software Definition can be found at Generally a program is free software if the program s users have four essential freedoms: 1. The freedom to run the program, for any purpose 2. The freedom to study how the program works, and change it so it does your computing as you wish (Access to the source code is a precondition for this) 3. Freedom to redistribute. 4. Freedom to distribute copies of your modified versions to others (Again access to the source code is a precondition for this.) BSD (Berkeley Software Distribution) Licenses are a family of permissive free software license, imposing minimal restrictions of covered software. MIT is also a Permissive Free Software License and originated in Massachusetts Institute of Technology (MIT)

9 MIT/BSD MIT License Only 20 lines! Liberal terms. Use this code however you like... BSD Adds a No-Advertising Clause

10 The GNU General Public License (GNU or GPL) is the most widely used free software license, which guarantees individuals, organizations, companies the freedoms to use, study, share (copy), and modify the software. Software that allows these rights is called free software and if the software is copyleft ensures those are retained. The license was originally written by Richard Stallman of the Free Software Foundation (FSF) for the GNU project. (From Wikipedia) Copyleft is a general method for making a program (or other work) free, and requiring all modified and extended versions of the program to be free as well. This is the GPL standard A directory of free software under the above license can be found at:

11 Where Are We? What is Open Source? Open Source Licenses Pros of Open Source Software Cons of Open Source Software Scenarios

12 Open Source Footprint Pros: People all over the look at the same code Potentially huge development teams Broader testing base All of which saves us $$$

13 Pros on Cost IF a component fits your system: Save many development hours Small customizations may be easy A lot of testing is done for you

14 Documentation Open source projects have many developers For them, documentation is a must Bad documentation indicates a bad project

15 Where Are We? What is Open Source? Open Source Licenses Pros of Open Source Software Cons of Open Source Software Scenarios

16 Cons to Open Source It may not always fit your needs Training your staff Hiring an Expert may be needed (Linux BSD)

17 Cons: Temperamental Community Make sure you contribute back, at least a little This community is full of 'early adopters' They influence people's opinions

18 Where Are We? What is Open Source? Open Source Licenses Pros of Open Source Software Cons of Open Source Software Free Software Scenarios

19 Free Software the other side of the coin Free software that does not fall under the GNU rules are free because they have advertising or ask for donations. Examples of this type of software are: 1. SpyBot Search and Destroy (Spyware removal) 2. Paint.net (Graphics Software) 3. Wordpress (Website or Blog creation tool) 4. SpiceWorks (Network Administration tool) 5. Untangle Lite (Free Firewall with an advanced version for a price) 6. Pfsense Free Firewall

20 Free Developers and Office tools MySQL can be downloaded at: SkySQL developed by the executives of MYSQL after the purchase by Oracle: Java can be downloaded at: html Perl can be downloaded at: Open Office can be downloaded at: Graphics tool Paint dot net can be downloaded at:

21 Free Microsoft Developers Tools Microsoft Offers a variety of free developers tools as express versions of their full software developers tools and can be downloaded from: Microsoft SQL Server Express versions can be downloaded at: These tools are suitable for developing small to medium web sites and windows applications

23 Free Programming Objects and Tools When developing a Web site or Application often programmers will leverage off of objects that have already been written. These objects are designed in C#, C++, Java, Visual Basic, ASP and other languages. Indian River County uses itextsharp a free library to create the Electronic Version of the Trim Notice. That allows you to create, adapt, inspect and maintain documents in the Portable Document Format (PDF) The Library can be downloaded at: If any Appraiser is interested in how we created the E-Trims they can me and I will send them a copy of the code and library used to create the Trim.

39 Where are we? What is Open Source? Open Source Licenses Pros of Open Source Software Cons of Open Source Software Free Software Scenarios (Firewalls)

40 Open Source / Free Firewalls If you were to do a Google search for open source firewalls you would be very surprised as to how many show up. So rather then try cover them all I will touch on a few that I am familiar with. Smoothwall Express Open Source and can be downloaded at: Smoothwall Express for corporations website is: Pfsense a free firewall for both home users and corporate web site:

41 Free Firewall Myths Hardware firewalls are better Myth The reality is there is no such thing as a "hardware firewall All firewalls are hardware that runs software Most Commercial firewalls are based on BSD or Linux

42 Open Source is Insecure Myth The mindset that because the source is open, it's insecure because everyone can see how it works No software relies on the obscurity of source code for security One of the Strengths of open source code is that all vulnerabilities are quickly identified and repaired due to the number of tests
