6. Doing great things for Love.
W h y d o w e d o i t
“.. The coordinating tools we have now –mailing list, Usenet, web blogs, wikis – those
tools turn love into a renewable building material. In the middle of the 90’s most
software was commercially manufactured but only visible means of support was love
plus mailing list… Perl, Apache, Linux.
.. Linux gets rebuild every night by people whose principal goal is allow it to exist the next
morning. This means that the ability to aggregate non financial motivations to get people
together outside of the profitable model have receive a huge competitive advantage…
… In the past we would do little things for love but great things required money, now
you can do big things for love.” -Clay Shirk on Love, Internet Style1

36. Finding a Balance
W h y d o w e d o i t ?
Is it possible to have a relationship
between Open Source and Security if
we adopt a posture of security as a first
class citizen in our organization.
This means raising the bar and our
standards following best practices.

Final Thoughts
Source: https://www.owasp.org/images/b/b0/OWASP_Top_10_2017_RC2_Final.pdf
• Open Source not always means insecurity.
• Contribute as much as possible to the Open Source
community
• Do informed decisions before using an open source
component or software use some criteria items such as:
• Security issues reported.
• Frequency of bug fixes.
• Activity and Testing
• Patch often
