Description
TCP Wrappers is a host-based access control system that allows administrators to control who has access to various network services based on the IP address of the remote end of the connection. TCP Wrappers also provides logging information via syslog about both successful and unsuccessful connections. TCP Wrappers provides granular control over what services can be accessed over the network. Its logs show attempted access to services from non-authorized systems, which can help identify unauthorized access attempts.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-216381r959010_chk)

Determine if TCP Wrappers is configured. # inetadm -p | grep tcp_wrappers If the output of this command is "FALSE", this is a finding. The above command will check whether TCP Wrappers is enabled for all TCP-based services started by inetd. TCP Wrappers are enabled by default for sendmail and SunSSH (version 0.5.11). The use of OpenSSH access is controlled by the sshd_config file starting with Solaris 11.3. SunSSH is removed starting with Solaris 11.4. Individual inetd services may still be configured to use TCP Wrappers even if the global parameter (above) is set to "FALSE". To check the status of individual inetd services, use the command: # for svc in `inetadm | awk '/svc:\// { print $NF }'`; do val=`inetadm -l ${svc} | grep -c tcp_wrappers=TRUE` if [ ${val} -eq 1 ]; then echo "TCP Wrappers enabled for ${svc}" fi done If the required services are not configured to use TCP Wrappers, this is finding. # ls /etc/hosts.deny # ls /etc/hosts.allow If these files are not found, this is a finding.

Fix Text (F-17615r371232_fix)

The root role is required. Configure allowed and denied hosts per organizational policy. 1. Create and customize the policy in /etc/hosts.allow: # echo "ALL: [net]/[mask] , [net]/[mask], ..." > /etc/hosts.allow where each [net>/[mask> combination (for example, the Class C address block "192.168.1.0/255.255.255.0") can represent one network block in use by the organization that requires access to this system. 2. Create a default deny policy in /etc/hosts.deny: # echo "ALL: ALL" >/etc/hosts.deny 3. Enable TCP Wrappers for all services started by inetd: # inetadm -M tcp_wrappers=TRUE
