secconfig(8) System Manager's Manual secconfig(8) NAME
secconfig, secsetup - Security features setup graphical interface (Enhanced Security) SYNOPSIS
/usr/sbin/sysman secconfig NOTE: The secsetup utility has been replaced by the secconfig graphical interface. DESCRIPTION
The utility is a graphical interface used to select the level of system security needed. It can convert from Base to enhanced security mode, and configure base and enhanced security features. If you are using secconfig to enable Enhanced security, you must first have loaded the enhanced security subsets. You can run while the system is in multiuser mode. However, if you change the security level, the change is not completed until you reboot the system. For both base and enhanced security, the secconfig utility allows you to enable segment sharing, to enable access control lists (ACLs), and to restrict the setting of the execute bit to root only. For enhanced security, the secconfig utility additionally allows you to configure security support from simple shadow passwords all the way to a strict C2 level of security. Shadow password support is an easy method for system administrators, who do not wish to use all of the extended security features, to move each user's password out of /etc/passwd and into the extended user profile database (auth.db. You can use the Custom mode if you wish to select additional security features, such as breakin detection and evasion, automatic database trimming, and password controls. When converting from base to enhanced security, secconfig updates the system default database (/etc/auth/system/default) and uses the con- vuser utility to migrate user accounts. While it is possible to convert user accounts from enhanced back to base, the default encryption algorithms and supported password lengths differ between base and enhanced security, and thus user account conversions do not succeed without a password change. NOTE: Because of the page table sharing mechanism used for shared libraries, the normal file system permissions are not adequate to protect against unauthorized reading. The secconfig interface allows you to disable segment sharing. The change in segment sharing takes effect at the next reboot. FILES
