C++ analysis rules

Hi, I have active my C++ quality profile, and I suppose this rules are active by default, and I can not deactive them, am i right? I also test other cases, adding some code like this
" char p[100]; char s[90]; memcpy(p,s,100);" I think it should report 3 issues, not initialized and should replace memcpy to memcpy_s, but after running SonarQub, it told me no errors in my project.
