To keep your system secure, you should take a two-pronged approach. On the one hand, learn from the mistakes of your predecessors by reading legacy documents. On the other hand, you should constantly keep up-to-date on the latest security issues. The resources in this chapter will help you do both.
Many Linux flaws and weaknesses are Linux-specific. Hence, you should start with Linux patches, updates, and advisories. See Table D.1 for links to such information.
