Vuln Rule Version CCI Severity Title Description
SV-28596r1_rule GEN000400 CCI-000048 MEDIUM The Department of Defense (DoD) login banner must be displayed immediately prior to, or as part of, console login prompts. Failure to display the login banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.System AdministratorECWM-1
SV-39815r1_rule GEN000460 CCI-000044 MEDIUM The system must disable accounts after three consecutive unsuccessful login attempts. Disabling accounts after a limited number of unsuccessful login attempts improves protection against password guessing attacks.System AdministratorECLO-1, ECLO-2
SV-27094r1_rule GEN000480 CCI-002238 MEDIUM The delay between login prompts following a failed login attempt must be at least 4 seconds. Enforcing a delay between successive failed login attempts increases protection against automated password guessing attacks. System AdministratorECLO-1, ECLO-2
SV-27105r1_rule GEN000560 CCI-000366 HIGH The system must not have accounts configured with blank or null passwords. If an account is configured for password authentication but does not have an assigned password, it may be possible to log into the account without authentication. If the root user is configured without a password, the entire system may be compromised. For user accounts not using password authentication, the account must be configured with a password lock value instead of a blank or null value. System AdministratorIAIA-1, IAIA-2
SV-39820r1_rule GEN000880 CCI-000366 MEDIUM The root account must be the only account having an UID of 0. If an account has an UID of 0, it has root authority. Multiple accounts with an UID of 0 afford more opportunity for potential intruders to guess a password for a privileged account.System AdministratorECLP-1
SV-774r2_rule GEN000900 CCI-000366 LOW The root user's home directory must not be the root directory (/). Changing the root home directory to something other than / and assigning it a 0700 protection makes it more difficult for intruders to manipulate the system by reading the files that root places in its default directory. It also gives root the same discretionary access control for root's home directory as for the other plain user home directories.System AdministratorECCD-1, ECCD-2
SV-775r2_rule GEN000920 CCI-000225 MEDIUM The root account's home directory (other than /) must have mode 0700. Permissions greater than 0700 could allow unauthorized users access to the root home directory.System AdministratorECCD-1, ECCD-2
SV-776r3_rule GEN000940 CCI-000366 MEDIUM The root account's executable search path must be the vendor default and must contain only absolute paths. The executable search path (typically the PATH environment variable) contains a list of directories for the shell to search to find executables. If this path includes the current working directory or other relative paths, executables in these directories may be executed instead of system commands. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon or two consecutive colons, this is interpreted as the current working directory. Entries starting with a slash (/) are absolute paths.System Administrator
SV-27143r1_rule GEN000980 CCI-000770 MEDIUM The system must prevent the root account from directly logging in except from the system console. Limiting the root account direct logins to only system consoles protects the root account from direct unauthorized access from a non-console device. System AdministratorECPA-1
SV-27069r1_rule GEN000380 CCI-000366 LOW All GIDs referenced in the /etc/passwd file must be defined in the /etc/group file. If a user is assigned the GID of a group not existing on the system, and a group with the same GID is subsequently created, the user may have unintended rights to the group. System AdministratorECSC-1
SV-39832r2_rule GEN001260 CCI-001314 MEDIUM System log files must have mode 0640 or less permissive. If the system log files are not protected, unauthorized users could change the logged data, eliminating its forensic value.System Administrator
SV-788r2_rule GEN001800 CCI-000225 MEDIUM All skeleton files (typically those in /etc/skel) must have mode 0644 or less permissive. If the skeleton files are not protected, unauthorized personnel could change user startup parameters and possibly jeopardize user files. System AdministratorECLP-1
SV-27166r1_rule GEN001320 CCI-000225 MEDIUM NIS/NIS+/yp files must be owned by root, sys, or bin. NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture. System AdministratorECLP-1
SV-27171r1_rule GEN001340 CCI-000225 MEDIUM NIS/NIS+/yp files must be group-owned by root, sys, or bin. NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture. System AdministratorECLP-1
SV-27175r1_rule GEN001360 CCI-000225 MEDIUM The NIS/NIS+/yp command files must have mode 0755 or less permissive. NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. Unauthorized modification of these files could compromise these processes and the system.System AdministratorECLP-1
SV-39821r1_rule GEN001300 CCI-001499 MEDIUM Library files must have mode 0755 or less permissive. Unauthorized access could destroy the integrity of the library files.System AdministratorDCSL-1
SV-796r2_rule GEN001240 CCI-001499 MEDIUM System files, programs, and directories must be group-owned by a system group. Restricting permissions will protect the files from unauthorized modification.System AdministratorECLP-1
SV-39826r1_rule GEN001400 CCI-000225 MEDIUM The /etc/shadow (or equivalent) file must be owned by root. The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification. Failure to give ownership of sensitive files or utilities to root provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-798r2_rule GEN001380 CCI-000225 MEDIUM The /etc/passwd file must have mode 0644 or less permissive. If the password file is writable by a group owner or the world, the risk of password file compromise is increased. The password file contains the list of accounts on the system and associated information.System AdministratorECLP-1
SV-800r2_rule GEN001420 CCI-000225 MEDIUM The /etc/shadow (or equivalent) file must have mode 0400. The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification. The file also contains password hashes which must not be accessible to users other than root.System AdministratorECLP-1
SV-27271r1_rule GEN002680 CCI-000162 MEDIUM System audit logs must be owned by root. Failure to give ownership of system audit log files to root provides the designated owner and unauthorized users with the potential to access sensitive information.System AdministratorECTP-1
SV-27282r1_rule GEN002700 CCI-000163 MEDIUM System audit logs must have mode 0640 or less permissive. If a user can write to the audit logs, audit trails can be modified or destroyed and system intrusion may not be detected. System audit logs are those files generated from the audit system and do not include activity, error, or other log files created by application software.System AdministratorECTP-1
SV-27287r1_rule GEN002720 CCI-000126 MEDIUM The audit system must be configured to audit failed attempts to access files and programs. If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. System AdministratorECAR-1, ECAR-2, ECAR-3
SV-27292r1_rule GEN002740 CCI-000126 MEDIUM The audit system must be configured to audit file deletions. If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. System AdministratorECAR-1, ECAR-2, ECAR-3
SV-27298r1_rule GEN002760 CCI-000347 MEDIUM The audit system must be configured to audit all administrative, privileged, and security actions. If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. System AdministratorECAR-1, ECAR-2, ECAR-3
SV-27303r1_rule GEN002800 CCI-000126 MEDIUM The audit system must be configured to audit login, logout, and session initiation. If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. System AdministratorECAR-1, ECAR-2, ECAR-3
SV-27309r1_rule GEN002820 CCI-000126 MEDIUM The audit system must be configured to audit all discretionary access control permission modifications. If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. System AdministratorECAR-1, ECAR-2, ECAR-3
SV-39885r1_rule GEN003740 CCI-000225 MEDIUM The inetd.conf file must have mode 0440 or less permissive. The Internet service daemon configuration files must be protected as malicious modification could cause Denial of Service or increase the attack surface of the system.System AdministratorECLP-1
SV-823r2_rule GEN003760 CCI-000225 MEDIUM The services file must be owned by root or bin. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-824r2_rule GEN003780 CCI-000225 MEDIUM The services file must have mode 0444 or less permissive. The services file is critical to the proper operation of network services and must be protected from unauthorized modification. Unauthorized modification could result in the failure of network services.System AdministratorECLP-1
SV-39828r1_rule GEN001780 CCI-000366 LOW Global initialization files must contain the mesg -n or mesg n commands. If the mesg -n or mesg n command is not placed into the system profile, messaging can be used to cause a Denial of Service attack.System AdministratorECSC-1
SV-40493r1_rule GEN004360 CCI-000225 MEDIUM The alias file must be owned by root. If the alias file is not owned by root, an unauthorized user may modify the file to add aliases to run malicious code or redirect email.System AdministratorECLP-1
SV-835r2_rule GEN004440 CCI-000366 LOW Sendmail logging must not be set to less than nine in the sendmail.cf file. If Sendmail is not configured to log at level 9, system logs may not contain the information necessary for tracking unauthorized use of the Sendmail service.System AdministratorECAR-1, ECAR-2, ECAR-3
SV-41546r1_rule GEN004460 CCI-000126 MEDIUM The system syslog service must log informational and more severe SMTP service messages. If informational and more severe SMTP service messages are not logged, malicious activity on the system may go unnoticed.System AdministratorECSC-1
SV-28404r1_rule GEN004880 CCI-000225 MEDIUM The ftpusers file must exist. The ftpusers file contains a list of accounts not allowed to use FTP to transfer files. If this file does not exist, then unauthorized accounts can utilize FTP. System AdministratorECCD-1, ECCD-2
SV-28410r1_rule GEN004920 CCI-000225 MEDIUM The ftpusers file must be owned by root. If the file ftpusers is not owned by root, an unauthorized user may modify the file to allow unauthorized accounts to use FTP. System AdministratorECLP-1
SV-28413r1_rule GEN004940 CCI-000225 MEDIUM The ftpusers file must have mode 0640 or less permissive. Excessive permissions on the ftpusers file could permit unauthorized modification. Unauthorized modification could result in Denial of Service to authorized FTP users or permit unauthorized users to access the FTP service.System AdministratorECLP-1
SV-28419r3_rule GEN005080 CCI-000366 HIGH The TFTP daemon must operate in secure mode which provides access only to a single directory on the host file system. Secure mode limits TFTP requests to a specific directory. If TFTP is not running in secure mode, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability. System AdministratorECSC-1
SV-40392r1_rule GEN005100 CCI-000225 HIGH The TFTP daemon must have mode 0755 or less permissive. If TFTP runs with the setuid or setgid bit set, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.System AdministratorECPA-1
SV-867r2_rule GEN006400 CCI-001435 MEDIUM The Network Information System (NIS) protocol must not be used. Due to numerous security vulnerabilities existing within NIS, it must not be used. Possible alternative directory services are NIS+ and LDAP.System AdministratorInformation Assurance OfficerECSC-1
SV-27184r1_rule GEN001440 CCI-000225 LOW All interactive users must be assigned a home directory in the /etc/passwd file. If users do not have a valid home directory, there is no place for the storage and control of files they own.System AdministratorECSC-1
SV-27192r1_rule GEN001460 CCI-000225 LOW All interactive user home directories defined in the /etc/passwd file must exist. If a user has a home directory defined that does not exist, the user may be given the / directory, by default, as the current working directory upon logon. This could create a Denial of Service because the user would not be able to perform useful tasks in this location.System AdministratorECSC-1
SV-39837r3_rule GEN001600 CCI-000366 MEDIUM Run control scripts' executable search paths must contain only absolute paths. The executable search path (typically the PATH environment variable) contains a list of directories for the shell to search to find executables. If this path includes the current working directory or other relative paths, executables in these directories may be executed instead of system commands. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon or two consecutive colons, this is interpreted as the current working directory. Paths starting with a slash (/) are absolute paths.System Administrator
SV-40806r1_rule GEN002120 CCI-000366 MEDIUM The /etc/shells (or equivalent) file must exist. The shells file (or equivalent) lists approved default shells. It helps provide layered defense to the security approach by ensuring users cannot change their default shell to an unauthorized shell that may not be secure.System AdministratorECSC-1
SV-28444r1_rule GEN005740 CCI-000225 MEDIUM The NFS export configuration file must be owned by root. Failure to give ownership of the NFS export configuration file to root provides the designated owner and possible unauthorized users with the potential to change system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-28446r1_rule GEN005760 CCI-000225 LOW The NFS export configuration file must have mode 0644 or less permissive. Excessive permissions on the NFS export configuration file could allow unauthorized modification of the file, which could result in Denial of Service to authorized NFS exports and the creation of additional unauthorized exports.System AdministratorECCD-1, ECCD-2, ECLP-1
SV-955r2_rule GEN000000-SOL00220 CCI-000032 MEDIUM The /usr/aset/userlist file must exist. If the userlist file does not exist, then an unauthorized user may exist in the /etc/passwd file.System AdministratorECSC-1
SV-956r2_rule GEN000000-SOL00240 CCI-000225 MEDIUM The /usr/aset/userlist file must be owned by root. If the userlist file is not owned by root, then an unauthorized user can modify the file and enter an unauthorized user.System AdministratorECLP-1
SV-957r2_rule GEN000000-SOL00260 CCI-000225 MEDIUM The /usr/aset/userlist file must have mode 0600 or less permissive. A permission mask not set to the required level could allow unauthorized access to sensitive system files and resources.System AdministratorECLP-1
SV-27317r1_rule GEN002960 CCI-000225 MEDIUM Access to the cron utility must be controlled using the cron.allow and/or cron.deny file(s). The cron facility allows users to execute recurring jobs on a regular and unattended basis. The cron.allow file designates accounts allowed to enter and execute jobs using the cron facility. If neither cron.allow nor cron.deny exists, then any account may use the cron facility. This may open the facility up for abuse by system intruders and malicious users.System AdministratorECLP-1
SV-27323r1_rule GEN002980 CCI-000225 MEDIUM The cron.allow file must have mode 0600 or less permissive. A cron.allow file that is readable and/or writable by other than root could allow potential intruders and malicious users to use the file contents to help discern information, such as who is allowed to execute cron programs, which could be harmful to overall system and network security.System AdministratorECLP-1
SV-27340r1_rule GEN003080 CCI-000225 MEDIUM Crontab files must have mode 0600 or less permissive. To protect the integrity of scheduled system jobs and prevent malicious modification to these jobs, crontab files must be secured. System AdministratorECLP-1
SV-27342r1_rule GEN003100 CCI-000225 MEDIUM Cron and crontab directories must have mode 0755 or less permissive. To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. System AdministratorECLP-1
SV-27345r1_rule GEN003120 CCI-000225 MEDIUM Cron and crontab directories must be owned by root or bin. Incorrect ownership of the cron or crontab directories could permit unauthorized users the ability to alter cron jobs and run automated jobs as privileged users. Failure to give ownership of cron or crontab directories to root or to bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-27347r1_rule GEN003140 CCI-000225 MEDIUM Cron and crontab directories must be group-owned by root, sys, or bin. To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. Failure to give group-ownership of cron or crontab directories to a system group provides the designated group and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-27354r1_rule GEN003180 CCI-000225 MEDIUM The cronlog file must have mode 0600 or less permissive. Cron logs contain reports of scheduled system activities and must be protected from unauthorized access or manipulation. System AdministratorECLP-1, ECTP-1
SV-27376r1_rule GEN003280 CCI-000225 MEDIUM Access to the at utility must be controlled via the at.allow and/or at.deny file(s). The at facility selectively allows users to execute jobs at deferred times. It is usually used for one-time jobs. The at.allow file selectively allows access to the at facility. If there is no at.allow file, there is no ready documentation of who is allowed to submit at jobs.System AdministratorECLP-1
SV-27380r1_rule GEN003300 CCI-000225 MEDIUM The at.deny file must not be empty if it exists. On some systems, if there is no at.allow file and there is an empty at.deny file, then the system assumes everyone has permission to use the at facility. This could create an insecure setting in the case of malicious users or system intruders.trueSystem AdministratorInformation Assurance OfficerECLP-1
SV-27388r1_rule GEN003340 CCI-000225 MEDIUM The at.allow file must have mode 0600 or less permissive. Permissions more permissive than 0600 (read and write for the owner) may allow unauthorized or malicious access to the at.allow and/or at.deny files.System AdministratorECLP-1
SV-1023r2_rule GEN006240 CCI-000381 MEDIUM The system must not run an Internet Network News (INN) server. Internet Network News (INN) servers access Usenet newsfeeds and store newsgroup articles. INN servers use the Network News Transfer Protocol (NNTP) to transfer information from the Usenet to the server and from the server to authorized remote hosts. If this function is necessary to support a valid mission requirement, its use must be authorized and approved in the system accreditation package.System AdministratorInformation Assurance OfficerECSC-1
SV-40291r2_rule GEN006100 CCI-000225 MEDIUM The smb.conf file must be owned by root. The smb.conf file allows access to other machines on the network and grants permissions to certain users. If it is owned by another user, the file may be maliciously modified and the Samba configuration could be compromised.System Administrator
SV-40294r2_rule GEN006140 CCI-000225 MEDIUM The smb.conf file must have mode 0644 or less permissive. If the smb.conf file has excessive permissions, the file may be maliciously modified and the Samba configuration could be compromised.System Administrator
SV-40284r1_rule GEN006160 CCI-000225 MEDIUM The smbpasswd file must be owned by root. If the smbpasswd file is not owned by root, the smbpasswd file may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.System AdministratorECLP-1
SV-39811r1_rule GEN001120 CCI-000770 MEDIUM The system must not permit root logins using remote access programs such as SSH. Even though communications are encrypted, an additional layer of security may be gained by extending the policy of not logging directly on as root. In addition, logging in with a user-specific account preserves the audit trail.System AdministratorECPA-1
SV-27246r1_rule GEN002340 CCI-000225 MEDIUM Audio devices must be owned by root. Globally Accessible audio and video devices have proven to be security hazards. There is software that can activate system microphones and video devices connected to user workstations and/or X terminals. Once the microphone has been activated, it is possible to eavesdrop on otherwise private conversations without the victim being aware of it. This action effectively changes the user's microphone to a bugging device.System AdministratorECLP-1
SV-39890r3_rule GEN006120 CCI-000225 MEDIUM The smb.conf file must be group-owned by root, bin, or sys. If the group owner of the smb.conf file is not root or a system group, the file may be maliciously modified and the Samba configuration could be compromised.System Administrator
SV-40287r1_rule GEN006180 CCI-000225 MEDIUM The smbpasswd file must be group-owned by root. If the smbpasswd file is not group-owned by root, the smbpasswd file may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.System AdministratorECLP-1
SV-40289r1_rule GEN006200 CCI-000225 MEDIUM The smbpasswd file must have mode 0600 or less permissive. If the smbpasswd file has a mode more permissive than 0600, the smbpasswd file may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.System AdministratorECLP-1
SV-27251r1_rule GEN002360 CCI-000225 MEDIUM Audio devices must be group-owned by root, sys, or bin. Without privileged group owners, audio devices will be vulnerable to being used as eaves-dropping devices by malicious users or intruders to possibly listen to conversations containing sensitive information. System AdministratorECLP-1
SV-27132r1_rule GEN000800 CCI-000200 MEDIUM The system must prohibit the reuse of passwords within five iterations. If a user, or root, used the same password continuously or was allowed to change it back shortly after being forced to change it to something else, it would provide a potential intruder with the opportunity to keep guessing at one user's password until it was guessed correctly. System AdministratorIAIA-1, IAIA-2
SV-27207r1_rule GEN001660 CCI-000225 MEDIUM All system start-up files must be owned by root. System start-up files not owned by root could lead to system compromise by allowing malicious users or applications to modify them for unauthorized purposes. This could lead to system and network compromise. System AdministratorECLP-1
SV-27213r1_rule GEN001680 CCI-000225 MEDIUM All system start-up files must be group-owned by root, sys, or bin. If system start-up files do not have a group owner of root or a system group, the files may be modified by malicious users or intruders.System AdministratorECLP-1
SV-4245r2_rule GEN000000-SOL00100 CCI-000225 MEDIUM The /etc/security/audit_user file must have mode 0640 or less permissive. Audit_user is a sensitive file that, if compromised, would allow a malicious user to select auditing parameters to ignore his sessions. This would allow malicious operations the auditing subsystem would not log for that user.System AdministratorECLP-1
SV-4273r2_rule GEN006260 CCI-000225 MEDIUM The /etc/news/hosts.nntp (or equivalent) must have mode 0600 or less permissive. Excessive permissions on the hosts.nntp file may allow unauthorized modification which could lead to Denial-of-Service to authorized users or provide access to unauthorized users.System AdministratorECLP-1
SV-4274r2_rule GEN006280 CCI-000225 MEDIUM The /etc/news/hosts.nntp.nolimit (or equivalent) must have mode 0600 or less permissive. Excessive permissions on the hosts.nntp.nolimit file may allow unauthorized modification which could lead to Denial-of-Service to authorized users or provide access to unauthorized users.System AdministratorECLP-1
SV-4275r2_rule GEN006300 CCI-000225 MEDIUM The /etc/news/nnrp.access (or equivalent) must have mode 0600 or less permissive. Excessive permissions on the nnrp.access file may allow unauthorized modification which could lead to Denial-of-Service to authorized users or provide access to unauthorized users.System AdministratorECLP-1
SV-4276r2_rule GEN006320 CCI-000225 MEDIUM The /etc/news/passwd.nntp file (or equivalent) must have mode 0600 or less permissive. File permissions more permissive than 0600 for /etc/news/passwd.nntp may allow access to privileged information by system intruders or malicious users.System AdministratorECLP-1
SV-40487r1_rule GEN006340 CCI-000225 MEDIUM Files in /etc/news must be owned by root. If critical system files are not owned by a privileged user, system integrity could be compromised.System AdministratorECLP-1
SV-40489r1_rule GEN006360 CCI-000225 MEDIUM The files in /etc/news must be group-owned by root. If critical system files do not have a privileged group owner, system integrity could be compromised.System AdministratorECLP-1
SV-39817r1_rule GEN005500 CCI-001436 HIGH The SSH daemon must be configured to only use the SSHv2 protocol. SSHv1 is not a DoD-approved protocol and has many well-known vulnerability exploits. Exploits of the SSH daemon could provide immediate root access to the system.System AdministratorDCPP-1
SV-40041r1_rule GEN000000-SOL00400 CCI-000126 MEDIUM The NFS server must have logging implemented. Filesystem logging, especially for NFS exported file systems, can be critical to detecting data misuse and possible hardware/system errors that may, otherwise, go unnoticed.System AdministratorECAR-1, ECAR-2, ECAR-3
SV-40021r1_rule GEN003640 CCI-000553 MEDIUM The root file system must employ journaling or another mechanism ensuring file system consistency. File system journaling, or logging, can allow reconstruction of file system data after a system crash, thus, preserving the integrity of data that may have otherwise been lost. Journaling file systems typically do not require consistent checks upon booting after a crash, which can improve system availability. Some file systems employ other mechanisms to ensure consistency which also satisfy this requirement.System AdministratorECAR-1, ECAR-2, ECAR-3
SV-4321r2_rule GEN006060 CCI-001436 MEDIUM The system must not run Samba unless needed. Samba is a tool used for the sharing of files and printers between Windows and UNIX operating systems. It provides access to sensitive files and, therefore, poses a security risk if compromised.System AdministratorECSC-1
SV-4351r2_rule GEN000000-SOL00080 CCI-000225 MEDIUM The /etc/security/audit_user file must be group-owned by root, sys, or bin. The Solaris audit_user file allows for selective auditing or non-auditing of features for certain users. If it is not protected, it could be compromised and used to mask audit events.

Failure to give group ownership of the NFS export configuration file to root or system groups provides the designated group owner and possible unauthorized users with the potential to change system configuration which could weaken the system's security posture.System AdministratorECLP-1
SV-40295r2_rule GEN006225 CCI-000366 MEDIUM Samba must be configured to use an authentication mechanism other than "share." Samba share authentication does not provide for individual user identification and must not be used.System Administrator
SV-40297r2_rule GEN006235 CCI-000366 MEDIUM Samba must be configured to not allow guest access to shares. Guest access to shares permits anonymous access and is not permitted.System Administrator
SV-26931r1_rule GEN007840 CCI-000366 MEDIUM The DHCP client must be disabled if not needed. DHCP allows for the unauthenticated configuration of network parameters on the system by exchanging information with a DHCP server.System AdministratorECSC-1
SV-40726r1_rule GEN008060 CCI-000225 MEDIUM If the system is using LDAP for authentication or account information the LDAP client configuration file must have mode 0600 or less permissive. LDAP can be used to provide user authentication and account information, which are vital to system security. The LDAP client configuration must be protected from unauthorized modification.System AdministratorECLP-1
SV-40727r1_rule GEN008080 CCI-000225 MEDIUM If the system is using LDAP for authentication or account information, the LDAP configuration file must be owned by root.

The LDAP client configuration must be protected from unauthorized modification.System AdministratorECLP-1
SV-26965r1_rule GEN008440 CCI-000366 LOW Automated file system mounting tools must not be enabled unless needed. Automated file system mounting tools may provide unprivileged users with the ability to access local media and network shares. If this access is not necessary for the system’s operation, it must be disabled to reduce the risk of unauthorized access to these resources.System AdministratorECSC-1
SV-26968r1_rule GEN008460 CCI-000366 LOW The system must have USB disabled unless needed. USB is a common computer peripheral interface. USB devices may include storage devices that could be used to install malicious software on a system or exfiltrate data. trueSystem AdministratorECSC-1
SV-26974r2_rule GEN008520 CCI-001118 MEDIUM The system must employ a local firewall. A local firewall protects the system from exposing unnecessary or undocumented network services to the local enclave. If a system within the enclave is compromised, firewall protection on an individual system continues to protect it from attack.System Administrator
SV-26991r1_rule GEN008800 CCI-000351 LOW The system package management tool must cryptographically verify the authenticity of software packages during installation. To prevent the installation of software from unauthorized sources, the system package management tool must use cryptographic algorithms to verify the packages are authentic.System AdministratorECSC-1
SV-27013r1_rule GEN000000-SOL00250 CCI-000225 MEDIUM The /usr/aset/userlist file must be group-owned by root. The /usr/aset/userlist file is critical to system security and must be protected from unauthorized access.System AdministratorECLP-1
SV-27016r2_rule GEN000000-SOL00540 CCI-000225 MEDIUM The /etc/zones directory, and its contents, must be owned by root. Solaris zones configuration files must be protected against illicit creation, modification, and deletion.System AdministratorECLP-1
SV-27018r2_rule GEN000000-SOL00560 CCI-000225 MEDIUM The /etc/zones directory, and its contents, must be group-owned by root, sys, or bin. Solaris zones configuration files must be protected against illicit creation, modification, and deletion.System AdministratorECLP-1
SV-27019r2_rule GEN000000-SOL00580 CCI-000225 MEDIUM The /etc/zones directory, and its contents, must not be group- or world-writable. Solaris zones configuration files must be protected against illicit creation, modification, and deletion.System AdministratorECLP-1
SV-27277r1_rule GEN002690 CCI-000162 MEDIUM System audit logs must be group-owned by root, bin, or sys. Sensitive system and user information could provide a malicious user with enough information to penetrate further into the system.System AdministratorECLP-1, ECTP-1
SV-28632r1_rule GEN003624 CCI-001208 LOW The system must use a separate filesystem for /tmp (or equivalent). The use of separate filesystems for different paths can protect the system from failures resulting from a filesystem becoming full or failing.System AdministratorECSC-1
SV-39864r1_rule GEN003850 CCI-000197 HIGH The telnet daemon must not be running. The telnet daemon provides a typically unencrypted remote access service which does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log on using this service, the privileged user password could be compromised.GEN003850If an enabled telnet daemon is configured to only allow encrypted sessions, such as with Kerberos or the use of encrypted network tunnels, the risk of exposing sensitive information is mitigated, and this is not a finding.System AdministratorDCPP-1
