If the "even_deny_root" setting is not defined on both lines with the "pam_faillock.so" module name, this is a finding.Ĭonfigure the operating system to automatically lock the root account until the locked account is released by an administrator when three unsuccessful logon attempts in 15 minutes are made. ![]() Interestingly enough, if I use regedit.exe to perform the SAME operation, it succeedes in both creating, deleting, or changing the default value. # grep pam_faillock.so /etc/pam.d/password-auth-acĪuth required pam_faillock.so preauth silent audit deny=3 even_deny_root fail_interval=900Īuth pam_faillock.so authfail audit deny=3 even_deny_root fail_interval=900 On other PCs running Windows 7 or WindThe operation succeedes. Verify the operating system automatically locks the root account until it is released by an administrator when three unsuccessful logon attempts in 15 minutes are made. Red Hat Enterprise Linux 7 Security Technical Implementation Guide Limits are imposed by locking the account. We tried to log in to the VM through SSH Secure Shell or Putty session as root (CASE 1) or by switching to root user after logging in by a normal user account (CASE 2). A virtual machine (VM) is not allowing us to log in with root user via ssh. By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. We are using PureApplication System W3700 v2.22.4.0.
