Question $22$Answer

a$.$

The value of kernel.yama.ptrace$\_$scope does not meet the security baseline and should be changed

b$.$

The value of kernel.ctrl$-$alt$-$del was $0$ as expected

c$.$

The value of kernel.core$\_$uses$\_$pid should be changed to $1$

d$.$

The value of kernel.sysrq was $0$ as expected

e$.$

The value of fs$.$suid$\_$dumpable meets the security baseline
