SEC401.4: Data Security Technologies
Overview
There is no silver bullet when it comes to security. However, there is one technology that would help solve a lot of security issues - although few companies deploy it correctly. This technology is cryptography. Concealing the meaning of a message can prevent unauthorized parties from reading sensitive information. During the first half of Day 4 we'll look at various aspects of cryptographic concepts and how they can be used in securing an organization's assets. A related discipline called steganography, or information hiding, is also covered. During the second half of the day, we shift our focus to the various types of prevention technologies that can be used to stop an adversary from gaining access to our organization (firewalls, intrusion prevention systems) and the various types of detection technologies that can detect the presence of an adversary on our networks (intrusion detection systems). These preventative and detective techniques can be deployed from a network and/or endpoint perspective; the similarities and differences in the application of these techniques will be explored.
