Keeping audit records on a remote system reduces the likelihood of audit records being changed or corrupted. Duplicating and protecting the audit trail on a separate system reduces the likelihood of an individual being able to deny performing an action. Solaris has supported rsyslog since version 11.1 and the differences between syslog and rsyslog are numerous. Solaris 11.4 installs rsyslog by default, but previous versions require a manual installation. When establishing a rsyslog server to forward to, it is important to consider the network requirements for this action. Note the following configuration options: There are three ways to forward message: the traditional UDP transport, which is extremely lossy but standard; the plain TCP based transport, which loses messages only during certain situations but is widely available; and the RELP transport, which does not lose messages but is currently available only as part of the rsyslogd 3.15.0 and above. Examples of each configuration: UDP *.* @remotesystemname TCP *.* @@remotesystemname RELP *.* :omrelp:remotesystemname:2514 Please note that a port number was given as there is no standard port for RELP.

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-17321r372631_chk

Fix: F-17319r372632_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 SunSSH (0.5.11) and sendmail that ship with Solaris 11 will automatically use TCP Wrappers to filter access if a hosts.allow or hosts.deny file exists.

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.

Passwords need to be changed at specific policy-based intervals; however, if the information system or application allows the user to immediately and continually change their password, then the password could be repeatedly changed in a short period of time, defeating the organization's policy regarding password reuse. Solaris 11.4 introduced new password security features that allow for a more granular approach to password duration parameters. The introduction of MAXDAYS, MINDAYS, and WARNDAYS allow the /etc/default/passwd configuration file to enforce a minimum password lifetime of a single day.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. The shorter the password is, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

Attackers that are able to exploit an inactive account can potentially obtain and maintain undetected access to an application. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems need to track periods of user inactivity and disable accounts after 35 days of inactivity. Such a process greatly reduces the risk that accounts will be hijacked, leading to a data compromise. This policy does not apply to either emergency accounts or infrequently used accounts. Infrequently used accounts are local logon accounts used by system administrators when network or normal logon/access is not available. Emergency accounts are administrator accounts created in response to crisis situations. Satisfies: SRG-OS-000003, SRG-OS-000118

On many systems, only the system administrator needs the ability to schedule jobs. Even though a given user is not listed in the "cron.allow" file, cron jobs can still be run as that user. The "cron.allow" file only controls administrative access to the "crontab" command for scheduling and modifying cron jobs. Much more effective access controls for the cron system can be obtained by using Role-Based Access Controls (RBAC).
Checks: C-17361r462445_chk

Check that "at" and "cron" users are configured correctly. # ls /etc/cron.d/cron.deny If cron.deny exists, this is a finding. # ls /etc/cron.d/at.deny If at.deny exists, this is a finding. # cat /etc/cron.d/cron.allow cron.allow should have a single entry for "root", or the cron.allow file is removed if using RBAC. If any accounts other than root that are listed and they are not properly documented with the IA staff, this is a finding. # wc -l /etc/cron.d/at.allow | awk '{ print $1 }' If the output is non-zero, this is a finding, or the at.allow file is removed if using RBAC.

A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the system but does not want to log out because of the temporary nature of the absence. Rather than be forced to wait for a period of time to expire before the user session can be locked, the operating system needs to provide users with the ability to manually invoke a session lock so users may secure their account should the need arise for them to temporarily vacate the immediate physical vicinity.

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.

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.

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-17382r372814_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.

Common attack vectors such as malicious association and ad hoc networks will allow an attacker to spoof a wireless access point (AP), allowing validated systems to connect to the malicious AP and enabling the attacker to monitor and record network traffic. These malicious APs can also serve to create a man-in-the-middle attack or be used to create a denial-of-service to valid network resources.

Remote access is any access to an organizational information system by a user (or an information system) communicating through an external, non-organization-controlled network (e.g., the Internet). Examples of remote access methods include dial-up, broadband, and wireless. Using cryptography ensures confidentiality of the remote access connections. The system will attempt to use the first cipher presented by the client that matches the server list. Listing the values "strongest to weakest" is a method to ensure the use of the strongest cipher available to secure the SSH connection. Note: SSH in Solaris 11.GA-11.3 used Sun Microsystem’s proprietary SUNWssh. In Solaris 11.3 OpenSSH was offered as optional software and in Solaris 11.4 OpenSSH is the only SSH offered. Both use the same /etc/ssh/sshd_config file and both, by default do not include the ciphers line.

When data is written to portable digital media, such as thumb drives, floppy diskettes, compact disks, and magnetic tape, etc., there is risk of data loss. 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. The employment of cryptography is at the discretion of the information owner/steward.

A file integrity baseline is a collection of file metadata used to evaluate the integrity of the system. A minimal baseline must contain metadata for all device files, setuid files, setgid files, system libraries, system binaries, and system configuration files. The minimal metadata must consist of the mode, owner, group owner, and modification times. For regular files, metadata must also include file size and a cryptographic hash of the file's contents.

Protection of log data includes assuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto separate media than the system being audited on an organizationally defined frequency helps to assure in the event of a catastrophic system failure, the audit records will be retained. This helps to ensure a compromise of the information system being audited does not also result in a compromise of the audit records. This requirement can be met by the operating system continuously sending records to a centralized logging server.

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-17472r373081_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-17470r373082_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.
