Among the most significant features of Red Hat Enterprise Linux is SELinux (Security Enhanced Linux), a powerful, kernel-level security layer that provides fine-grained control over what users and processes may access and do on a system.
|
By default, SELinux is enabled on Red Hat Enterprise Linux systems, enforcing a set of mandatory access controls that Red Hat calls the targeted policy. These access controls substantially enhance the security of the network services they target, but can sometimes affect the behavior of third-party applications and scripts that worked on previous versions of Red Hat Enterprise Linux.
Upon completion of this course, students should be able to:
• Understand the basics of SELinux
• Describe how SELinux operates within the Red Hat targeted policy
• Describe the tools available for working with this powerful capability
Content:
Introduction to SELinux
• Discretionary vs. Mandatory Access Controls
• The SELinux Solution
Using SELinux
• Enabling SELinux
• Enforcing vs. Permissive Modes
• Setting a Policy
• system-config-securitylevel and Other Tools
• The /selinux Filesystem
The Red Hat Targeted Policy
• Identifying Protected Services
• Disabling SELinux on a Per-Service Basis

Målgruppe for kurset
This course is intended for system administrators deploying or planning to deploy Red Hat Enterprise Linux, version 4, and so needing a foundation in SELinux concepts and implementation. The course is particularly useful for system administrators managing Enterprise Linux systems running versions 2.1 or 3 and migrating to version 4.
To succeed fully in this course, students should be able to:
• RHCE certification or equivalent work experience. Either RH133 and RH253, or RH300 is acceptable.
• An understanding of the Linux security model.
• Familiarity with some of the services protected by the Red Hat Targeted Policy. These services include: httpd, squid, bind,dhcpd, ypserv, ypbind, portmap, syslogd, ntpd, snmpd, mysqld,postgresql.
To assist students in determining if they have sufficient system administration knowledge to take RHS427, they should take the following pre-assessment questionnaires:
• RH033 Pre-assessment Questionnaire
• RH133 Pre-assessment Questionnaire
• RH253 Pre-assessment Questionnaire
In order to ensure that the prerequisites for RHS427 are met, students should expect to receive a high score for the RH033 and RH133 classes (36 points or more) and a moderate score for the RH253 class (24 points or more). If one or more of these scores falls below the recommended level, students should consider taking the related class before taking RHS427.

Sun Microsystems
Sun ble grunnlagt med én eneste visjon som drivkraft. En visjon om datamaskiner som kommuniserte med hverandre uansett hvem som hadde laget dem. En visjon om teknikk som arbeider for deg, ikke motarbeider deg. Mens andre utviklet varemerkebeskyttede og proprietære løsninger, fokuserte vi på å hjelpe bedrifter inn i nettverksæraen. Som et resultat av dette er vi blitt dotten i .com. Vi leverer systemer og programvare som oppfyller kravene til skalerbarhet og påliteligheten som er nødvendig for å drive den elektroniske markedsplassen.
