This beat is now ready to have Fedora 25 content added by the beat writer

Disable SSL 3.0 and RC4

The SSL 3.0 protocol and the RC4 cipher are considered insecure and vulnerable to attacks. As such, these two are disabled by default for all Fedora components that use the system-wide crypto policies. This includes gnutls and openssl libraries, and all the applications based on them.

Applications or environments that require SSL 3.0 or RC4 can use update-crypto-policies to globally switch to the LEGACY policy to enable SSL 3.0 and RC4.

Note (Use note tag) - All applications that use TLS from NSS are not affected by this change.

OpenSSH 7.1

The OpenSSH project continues to improve the security of network communication with the release of OpenSSH version 7.1. Details of the release are available at http://www.openssh.com/txt/release-7.1

Package Hardening

Packages compiled for Fedora 23 will be compiled with a position-independent code flag enabled by default. This was an optional setting that as a default will protect users from certain potential security vulnerabilities.

Standardized Passphrase Policy

A common password policy is being utilized to provide a set of consistent rules for password policies. These rules can be modified locally to fit user needs.

-=== SELinux Enhancements ===
-Different roles are now available, to allow finer-grained access control:
+[[Category:Docs Project]]
+[[Category:Draft documentation]]
-* <code>guest_t</code> does not allow running <code>setuid</code> binaries, making network connections, or using a GUI.
+[[Category:Documentation beats]]
-* <code>xguest_t</code> disallows network access except for HTTP via a Web browser, and no <code>setuid</code> binaries.
-* <code>user_t</code> is ideal for office users: prevents becoming root via <code>setuid</code> applications.
-* <code>staff_t</code> is same as <code>user_t</code>, except that root-level access via <code>sudo</code> is allowed.
-* <code>unconfined_t</code> provides full access, the same as when not using SELinux.
-Browser plug-ins wrapped with <code>nspluginwrapper</code>, which is the default, are confined by SELinux policy.
-=== Security Audit Package ===
-'''SecTool''' provides users with a tool that can check their systems for security issues. There are libraries included that allow for the customization of system tests. More information can be found at the project home:

-=== General Information ===
-A general introduction to the many proactive security features in Fedora, current status, and policies is available at http://fedoraproject.org/wiki/Security.
