UNIX for Dummies Questions & Answers

How are patches for vulnerabilities deployed for UNIX, and Linux?
How are customers alerted of patches and updates for each company?
Are the patches deployed automatically?
Is there a certain day that they are deployed or ready for use?

I have done several different kinds of search at Google, I am not sure of the response I am receiving.

There are several flavours of UNIX & Linux (hundres for each version) so it's not possible to go into details

Solaris UNIX - Customers are alerted via email if they are members of Sunsolve or via a valid Support Contract, Patches can be deployed manually or automatically via the inb-built patch manager software

Ubuntu LINUX -Customers are alerted via email if they are members of a valid Support Contract, Patches can be deployed manually or automatically via the in-built patch manager software - Update Manager

Sounds like a question for Research material for a Degree Assignment, but -------------------------------------------------------------------

Thanks Stevie, this is research material for a Degree Assignment. In my search I found information on Sendmail as a widely deployed mail transfer agent. I was not sure if this information was what I needed to follow. The information you provided pointed me in the right direction. Again, thank you.
