| If you are running x86_64 architecture, determine the values for sethostname: $ uname -m; ausyscall i386 sethostname; ausyscall x86_64 sethostname If the values returned are not identical verify that the system is configured to monitor network configuration changes for the i386 and x86_64 architectures: $ sudo egrep -w '(sethostname|setdomainname|/etc/issue|/etc/issue.net|/etc/hosts|/etc/sysconfig/network)' /etc/audit/audit.rules -a always,exit -F arch=b32 -S sethostname -S setdomainname -k audit_network_modifications -w /etc/issue -p wa -k audit_network_modifications -w /etc/issue.net -p wa -k audit_network_modifications -w /etc/hosts -p wa -k audit_network_modifications -w /etc/sysconfig/network -p wa -k audit_network_modifications -a always,exit -F arch=b64 -S sethostname -S setdomainname -k audit_network_modifications -w /etc/issue -p wa -k audit_network_modifications -w /etc/issue.net -p wa -k audit_network_modifications -w /etc/hosts -p wa -k audit_network_modifications -w /etc/sysconfig/network -p wa -k audit_network_modifications If the system is configured to watch for network configuration changes, a line should be returned for each file specified for both (and "-p wa" should be indicated for each). If the system is not configured to audit changes of the network configuration, this is a finding. |

| Add the following to "/etc/audit/audit.rules", setting ARCH to either b32 or b64 as appropriate for your system: # audit_network_modifications -a always,exit -F arch=ARCH -S sethostname -S setdomainname -k audit_network_modifications -w /etc/issue -p wa -k audit_network_modifications -w /etc/issue.net -p wa -k audit_network_modifications -w /etc/hosts -p wa -k audit_network_modifications -w /etc/sysconfig/network -p wa -k audit_network_modifications |
