TCP Wrappers are 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 provide logging information via syslog about both successful and unsuccessful connections.

Checks: C-50371r1_chk

Fix: F-51547r2_fix

The root role is required. To enable TCP Wrappers, run the following commands: 1. Create and customize your 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 your 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 The versions of SSH and sendmail that ship with Solaris 11 will automatically use TCP Wrappers to filter access if a hosts.allow or hosts.deny file exists.

Editing a system file with common tools such as vi, emacs, or gedit does not allow the auditing of changes made by an operator. This reduces the capability of determining which operator made security-relevant changes to the system.

Checks: C-50373r1_chk

Ask the operators if they use vi, emacs, or gedit to make changes to system files. If vi, emacs, or gedit are used to make changes to system files, this is a finding.

Fix: F-51549r1_fix

Advise the operators to use pdfedit or other appropriate command line tools to make system changes instead of vi, emacs, or gedit. Oracle Solaris includes administrative configuration files which use pfedit, and the solaris.admin.edit/path_to_file authorization is not recommended. Alternate commands exist which are both domain-specific and safer. For example, for the /etc/passwd, /etc/shadow, or /etc/user_attr files, use instead passwd, useradd, userdel, or usermod. For the /etc/group file, use instead groupadd, groupdel, or groupmod. For updating /etc/security/auth_attr, /etc/security/exec_attr, or /etc/security/prof_attr, the preferred command is profiles.

Mobile devices include portable storage media (e.g., USB memory sticks, external hard disk drives) and portable computing and communications devices with information storage capability (e.g., notebook/laptop computers, personal digital assistants, cellular telephones, digital cameras, audio recording devices). Auto execution vulnerabilities can result in malicious programs being automatically executed. Examples of information system functionality providing the capability for automatic execution of code are Auto Run and Auto Play. Auto Run and Auto Play are components of the Microsoft Windows operating system that dictate what actions the system takes when a drive is mounted. This requirement is designed to address vulnerabilities that arise when mobile devices such as USB memory sticks or other mobile storage devices are automatically mounted and applications are automatically invoked without user knowledge or acceptance.

If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be used to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation. Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. When temporary and emergency accounts are created, there is a risk the temporary account may remain in place and active after the need for the account no longer exists. To address this, in the event temporary accounts are required, accounts designated as temporary in nature must be automatically terminated after 72 hours. Such a process and capability greatly reduces the risk of accounts being misused, hijacked, or data compromised.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the operating system allows the user to consecutively reuse their password when the password has exceeded its defined lifetime, the end result is a password that is not changed, per policy requirements.

This control enhancement is implemented within the remote device (e.g., notebook/laptop computer) via configuration settings not configurable by the user of the device. An example of a non-remote communications path from a remote device is a virtual private network. When a non-remote connection is established using a virtual private network, the configuration settings prevent split-tunneling. Split-tunneling might otherwise be used by remote users to communicate with the information system as an extension of the system and to communicate with local resources, such as a printer or file server. The remote device, when connected by a non-remote connection, becomes an extension of the information system allowing dual communications paths, such as split-tunneling, in effect allowing unauthorized external connections into the system. This is a split-tunneling requirement that can be controlled via the operating system by disabling interfaces.

When data is written to digital media, such as hard drives, mobile computers, external/removable hard drives, personal digital assistants, flash/thumb drives, etc., there is risk of data loss and data compromise. An organizational assessment of risk guides the selection of media and associated information contained on the media requiring restricted access. Organizations need to document in policy and procedures the media requiring restricted access, individuals authorized to access the media, and the specific measures taken to restrict access. Fewer protection measures are needed for media containing information determined by the organization to be in the public domain, to be publicly releasable, or to have limited or no adverse impact if accessed by other than authorized personnel. In these situations, it is assumed the physical access controls where the media resides provide adequate protection. As part of a defense-in-depth strategy, the organization considers routinely encrypting information at rest on selected secondary storage devices. The employment of cryptography is at the discretion of the information owner/steward. The selection of the cryptographic mechanisms used is based upon maintaining the confidentiality and integrity of the information.

The network routing daemon, in.routed, manages network routing tables. If enabled, it periodically supplies copies of the system's routing tables to any directly connected hosts and networks and picks up routes supplied to it from other networks and hosts. Routing Internet Protocol (RIP) is a legacy protocol with a number of security weaknesses, including a lack of authentication, zoning, pruning, etc.

Checks: C-50647r1_chk

Determine if routing is disabled. # routeadm -p | egrep "routing |forwarding" | grep enabled If the command output includes "persistent=enabled" or "current=enabled", this is a finding.

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.

Checks: C-50653r1_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 SSH. 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.
