Remediation

Information

If ptrace is not required, ptrace can be disabled in multiple ways. 1. SELinux policy. # setsebool -P deny_ptrace on 2. Kernel sysctl. # sysctl -w kernel.yama.ptrace_scope=3 Or to make persistent , create /etc/sysctl.d/99-yama-ptrace_scope.conf kernel.yama.ptrace_scope=3 If you need further assistance, see the KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.
