CentOS

I'm pretty sure that webtaqtic has been unmaintained for years so if you were using that for newer php etc, you're probably vulnerable to any security problems discovered since it died.

Sticking with CentOS 7 is not a long term solution. It only has 7 months of life left before it hits the end of the road so moving to a newer distro is definitely your best bet since you'll need to do it sooner or later anyway.
