CISSP Exam Note (Domain 2: Telecommunications and Networking Security) – Key Concepts and Other Definitions
Rainbow Series
The Rainbow Series (sometimes known as the Rainbow Books) is a series of computer security standards published by the United States government in the 1980s and 1990s. They were originally published by the U.S. Department of Defense Computer Security Center, and then by the National Computer Security Center.
These standards describe a process of evaluation for trusted systems. In some cases, U.S. government entities (as well as private firms) would require formal validation of computer technology using this process as part of their procurement criteria. Many of these standards have influenced, and have been superseded by, the Common Criteria. Read more
CISSP Exam Note (Domain 2: Telecommunications and Networking Security) – Denial of Service Attack
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.
One common method of attack involves saturating the target (victim) machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

CISSP Review Notes – Notes I used to pass the exam
I became a Certified Information Systems Security Professional in 2007. I studied for nearly a year. It took so long because I had to self-study and I followed the best process I know (in essence what works for me). I was tempted on getting some of them brain dumps, but I thought better. I also debated whether I should attend one of them bootcamps. But I don’t think these bootcamps are worth what they are charging, typically $2500.00 for one week.
So I decided to go Spartan and go old school. I read the Shon Harris book and the official CISSP book for at least 2 hours every morning with the target of finishing a Domain per week. All the while highlighting stuff that I thought would be useful and worth highlighting. So you can imagine that process took me at least 20 weeks, reading two books. Read more
