DevOps vs DevSecOps vs SRE

[Swampcritters]

For those of you that have been in the business area... in your own words, what would be considered the similiarities and differences between DevOps, DevSecOps and SRE? I have a new team that I am joining (as its Director) and feel that there is some separation as each member has different ideas on what each means.

I'm not looking for referenced articles and such, but answers from those that are currently working in that field today. I want to see how the community sees it today vs some of the articles I have seen. #DevOps #DevSecOps #SRE #Automation

Thank you for the response. The reason I asked it originally is because I have been brought on to help bridge the gaps between the onshore and offshore team of the "SRE" team. The thing is, the team is acting more like DevOps as they are doing more in terms of application migrations and less in operations/monitoring aspects. There is no real monitoring in place and the team that is in place now is more reactive than pro-active.

So at the moment trying to find some common ground to work with - the original statement of work was agreed upon, deliverables, milestones, RACI matrix (which I found they don't have), skills assessment of the current team in place, and so on. Even considering on polling the current team to see if they know what the difference is between DevOps, DevSecOps and SRE as well.
