This section describes the security changes and enhancements available in Fedora 15.

Dynamic Firewall

Fedora 15 adds support for the optional firewall daemon (FirewallD), providing a dynamic firewall management with a D-Bus interface.

The previous firewall model with system-config-firewall, was static and required a full firewall restart for all changes, even simple ones. The dynamic firewall mode, makes it possible to change firewall settings without the need to restart the firewall for persistent connections. At this stage, it supports iptables, ip6table and ebtables. In Fedora 15 a simple tray applet shows the firewall state, enabling/disabling firewall services

For more details, consult the Fedora wiki pages, Fedora 15: Dynamic Firewall and FirewallD.

DNSSEC on workstations

In Fedora 15 comes in a new security feature that protects the end users and their workstations exposition against various DNS spoofing and DNS cache-poisoning attacks.

DNSSEC is an environment full tested in Fedora, as all major DNS servers in Fedora run with DNSSEC validation enabled by default since Fedora 11, giving to the Fedora Project a lot of experience from server environment. DNSSEC is aimed to secure all DNS traffic. NetworkManager uses the BIND nameserver as a DNSSEC resolver and all received DNS responses are proved to be correct. In case a particular domain is signed and failed to validate then resolver returns SERFVAIL instead of invalidated response, which means something is wrong.


First introduced in Fedora 14, OpenSCAP is a set of open source libraries providing an easier path for integration of the SCAP line of standards, managed by NIST and created to provide a standardized approach to maintaining the security of enterprise systems, such as automatically verifying the presence of patches, checking system security configuration settings, and examining systems for signs of compromise.

In Fedora 15, openscap, the set of open source libraries enabling integration of the SCAP line of standards, has been upgraded from version 0.6.3 to 0.6.8. During these development stage there has been introduced full support for perl regular expression by default, OVAL float type support, XSL transformation improvements and Dublin Core support, added OVAL schemas version 5.6 and improved XCCDF reporting.

secstate, the Security State Configuration Tool, has been rebuilt in Fedora 15 against version 0.4.1.

firstaidkit, the System Rescue Tool that automates simple and common system recovery tasks, has been upgraded from 0.2.17 to version 0.2.18.
