| == Crypto Policy ==
| | {{Docs_beat_open}} |
| | |
| <para>Beginning in Fedora 21, a system-wide crypto policy will be available for users to quickly setup the cryptographic options for their systems. Users that must meet certain cryptographic standards can make the policy change in <filename>//etc/crypto-policies/config</filename>, and run update-crypto-policies. At this point applications that utilize the default set of ciphers in the GnuTLS and OpenSSL libraries will follow the policy requirements.</para>
| |
| | |
| <para>The available options are: (1) <literal>LEGACY</literal>, which ensures compatibility with legacy systems - 64-bit security, (2) <literal>DEFAULT</literal>, a reasonable default for today's standards - 80-bit security, and (3) <literal>FUTURE</literal>, a conservative level that is believed to withstand any near-term future attacks - 128-bit security. These levels affect SSL/TLS settings, including elliptic curve, signature hash functions, and ciphersuites and key sizes.</para>

| == systemd PrivateDevices and PrivateNetwork ==
| |
| Fedora is now more secure, as many long-running '''systemd''' services now run with physical device access and/or network access turned off. See [https://fedoraproject.org/wiki/Documentation_System_Daemons_Beat#systemd_PrivateDevices_and_PrivateNetwork] (NOTE:xref)

| == Format Security ==
| |
| | |
| Starting with Fedora 21, all packages built by GCC will compile with the flag *-Werror=format-security* . While this change has no user-visible change, it represents a substantial effort by Fedora packagers to protect your system from an entire class of vulnerability.
