I can't open the security section in settings everytime I click it, it just takes me back to homescreen, what do I do? It is a brand new tablet and I already opened it once but I can't open it now.
You may need to clear the cache for your UI. You can also try to access it while in Safe Mode.
Since you haven't told us what brand or model your tab is, I cannot tell you what to look for as far as the name of your UI. Nor am I able to tell you have to access Safe Mode on your device. You can do a web search for these things yourself however.
