Security Information

Experience has shown that security through obscurity never works. Therefore, public disclosure allows for quicker and better solutions of security problems. In that respect, this page addresses Debian's status regarding various known security holes, which could potentially affect the Debian operating system.

The Debian project coordinates many security advisories with other free software vendors, and as a result, these advisories are published the same day a vulnerability is made public. In order to receive the latest Debian security advisories, please subscribe to the debian-security-announce mailing list.

Debian also participates in security standardization efforts:

Keeping your Debian System secure

The packages unattended-upgrades can be installed to keep the computer current with the latest security (and other) updates automatically. The wiki entry has more detailed information how to manually set up unattended-upgrades.

For more information about security issues in Debian, please refer to our FAQ and our documentation:
