#### Boolean Math (AND Logic) – CISSP Domain 3

| |
Today we’re going to take a quick look at the AND Boolean logic, which is covered in Domain 3 of the CISSP common body of knowledge (CBK).  To begin with, Boolean math is used to define the rules on how computer systems evaluate data. Because Boolean is based on a ... Read More

#### Encryption – CISSP Domain 3

| |
We’re circling back to some more CISSP-related materials. Today’s topic will be encryption, which can be found in CISSP Domain 3. By its very nature, encryption is meant to hide the meaning or intent of a communication from unintended recipients. This process takes place when a message is converted from ... Read More

#### Encoding – CISSP Domain 3

| |
Today we’re going to take a quick look at encoding, as covered in Domain 3 of the CISSP common body of knowledge (CBK). There is often some confusion between encoding and encryption, so one of the purposes of this article is to look at how the CBK defines encoding. Encoding ... Read More

#### Hashing Functions – CISSP Domain 3

| |
Today we’re going to take a quick look at hashing functions, as covered in Domain 3 of the CISSP common body of knowledge (CBK). There is often some confusion between hashing, encryption, and encoding, so one of the purposes of this article is to help differentiate between them. To start ... Read More
