+ <title>Dynamic Firewall</title>
+ <para>
+ Fedora 15 adds support for the optional firewall daemon
+ (<package>FirewallD</package>), providing a dynamic firewall
+ management with a D-Bus interface.
+ </para>
+ <para>
+ The previous firewall model with
+ <package>system-config-firewall</package>, was static and
+ required a full firewall restart for all changes, even simple
+ ones. This resulted in termination of filtered
+ connections. <package>Firewalld</package> can modify the
+ firewall dynamically and no firewall recreation is needed. At
+ this stage, it supports iptables, ip6tables and ebtables. In
+ Fedora 15 a simple tray applet shows the firewall state, and
+ firewall services can be enabled and disabled.

+ <title>DNSSEC on workstations </title>
+ <para>
+ 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.
+ </para>
+ <para>
+ 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. <package>NetworkManager</package> 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
+ <command>SERFVAIL</command> instead of invalidated response,
+ which means something is wrong.
+ </para>
+ <para>
+ For all details please refer to <ulink

+ on the Fedora wiki.
+ </para>
+ <para>
+ <package>dnssec-tools</package> version 1.8 in Fedora 15 is
+ the tool used to improve this feature.

+ <section>
+ <title>OpenSCAP</title>
+ <para>
+ First introduced in Fedora 14, <package>OpenSCAP</package> 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.
+ </para>
+ <para>
+ In Fedora 15, <package>openscap</package>, 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.
+ </para>
+ <para>
+ <package>secstate</package>, the Security State Configuration
+ Tool, has been rebuilt in Fedora 15 against version 0.4.1.
+ </para>
+ <para>
+ <package>firstaidkit</package>, the System Rescue Tool that
+ automates simple and common system recovery tasks, has been
+ upgraded from 0.2.17 to version 0.2.18.

+ <title>authoconfig ecryptfs</title>
+ <para>
+ Fedora 15 brings in improved support for eCryptfs, a stacked
+ cryptographic filesystem for Linux. Now when a
+ <package>ecryptfs</package> user logs in,
+ <application>authconfig</application> will automatically mount
+ his private encrypted part of the home directory.

+ <section>
+ <title>setroubleshoot</title>
+ <para>
+ The user interface of <package>setroubleshoot</package> has been
+ redesigned to make it easier to diagnose SELinux problems. In
+ the current setroubleshooter the "best" match is returned for a
+ solution to the customer. In the new redesign, all matches will
+ be returned. For example if samba tried to read content that it
+ is not allowed, we would like to tell the admin that he could
+ label the content <command>samba_share_t</command> or he could
+ set up SELinux to allow samba to share all content Read Only, or
+ Read Write, or samba should not be trying to read this content,
+ it could be a bug or an attack.
+ </para>
+ <para>
+ The interface has also been simplified with easier to
+ explain definitions, like
+ </para>
+<screen>
+If you want samba to share the entire system read/only, then
+you need to tell SELinux system about this, by setting the
+samba_export_all_ro boolean.
+
+Execute the following command as root.
+
+ setsebool -P samba_export_all_ro=1

+ <section>
+ <title>Remove setuid</title>
+ <para>
+ Fedora 15 removes <command>setuid</command> applications and
+ instead specifically assigns the capabilities required by an
+ application, modifing the spec files of most applications that
+ include a setuid application to remove the setuid flag and
+ change to file capabilities.
