Though people and businesses are benefiting from the many deployed open-sourced programs the world over, security still prevents most from shifting to their use as with big businesses. The many security issues that are inherent of open-systems due to the dispersal of development that may span the globe is quite alarming and without proper measures to address this. Enterprise software have inherent need for strong security and up-time, that is quite opposite of open-source development due to frequent and dispersed support facilities. These factors are deterring some companies from adopting them so more has to be done to address the security issue.
SaaS, being one of the models being applied for development of applications based on open-source is seeing a lot of criticism from the security standpoint. People used to have good views of the open-source trends that were sweeping the internet but after a few years of blunders and problems associated with it, there seems to be more concerns regarding the issue than answers. People have always been amiable to cheaper development yet security is one thing we all cannot take for granted, time may come when the industry may have the answer for all the security issues that are emerging but for now, we all await such developments for these issues.
