CompTIA Security+ SY0-501

Sometimes, the information you need is hidden in plain sight. In this video, you’ll learn how steganography can be used to store and hide information. << Previous Video: Cryptographic Keys Next: Stream and Block Ciphers >> The process of obfuscation is when you take one particular topic and you make it much more complex to […]

The keys used in cryptography may consist of many different characteristics. In this video, you’ll learn about key strength, the key exchange process, and real-time encryption and decryption. << Previous Video: Weak Encryption Next: Steganography >> Cryptography doesn’t rely on security through obscurity. With cryptography, you know practically everything about the cryptographic process. The entire

Not all encryption is equally secure. In this video, you’ll learn what makes an encryption method strong or weak. << Previous Video: Randomizing Cryptography Next: Cryptographic Keys >> When you start comparing different kinds of cryptography, you’ll find that some we refer to as strong cryptography, and others might be considered weak cryptography. We make

We rely heavily on randomization when using cryptography. In this video, you’ll learn about the importance of randomization and how random information is used to provide data security. << Previous Video: Hashing and Digital Signatures Next: Weak Encryption >> In an earlier video, I talked about encryption relying on randomisation. And here’s a good example.

A cryptographic hash can be used for many different tasks. In this video, you’ll learn about hashing, collisions, digital signatures, and more. << Previous Video: Symmetric and Asymmetric Encryption Next: Randomizing Cryptography >> A cryptographic hash allows you to take any amount of data– it can be a small bit of text, or it can

If you’re planning to implement cryptography, then you’ll probably be using either symmetric encryption or asymmetric encryption. In this video, you’ll learn about both of these valuable encryption mechanisms. << Previous Video: Cryptography Concepts Next: Hashing and Digital Signatures >> If you’ve implemented symmetric encryption using a single shared key for both the encryption process

The basics of cryptography are valuable fundamentals for building a secure network. In this video, you’ll learn about cryptographic terms, the value of the key, the concepts of confusion and diffusion, and more. << Previous Video: Data Roles and Retention Next: Symmetric and Asymmetric Encryption >> Cryptography is derived from the Greek word “kryptos,” which

Who owns your data, and how long do you keep copies of your data? In this video, you’ll learn about specific data roles and options for data retention. << Previous Video: Handling Sensitive Data Next: Cryptography Concepts >> In most organizations, data doesn’t exist on its own. There is a relationship between the data and

Different types of data need to be uniquely managed. In this video, you’ll learn about labeling sensitive data and some common sensitive data types. << Previous Video: Data Destruction Next: Data Roles and Retention >> In your organization, you’re going to be working with lots of different kinds of data. But not all of the

What’s the best way to permanently remove data from a storage device? In this video, you’ll learn about the challenges associated with destroying data. << Previous Video: Security Controls Next: Handling Sensitive Data >> As we think about the lifecycle of all of our systems and data, at some point there will be a need
