CompTIA Security+ SY0-701

Blockchain technology is the foundation of cryptocurrency, but it can also be used for many other purposes. In this video, you’ll learn how blockchain technology works behind the scenes. << Previous Video: Hashing and Digital Signatures Next Video: Certificates >> Blockchain technology is often described as a distributed ledger. This is a ledger that’s available […]

The hashing process can provide integrity, authentication, and non-repudiation. In this video, you’ll learn how hashes are created and how to use digital signatures. << Previous Video: Obfuscation Next Video: Blockchain Technology >> A cryptographic hash is used to represent data as a short string of text. Sometimes you’ll hear this referred to as a

Obfuscation can be used in IT security to hide information in unique ways. In this video, you’ll learn about steganography, tokenization, and data masking. << Previous Video: Encryption Technologies Next Video: Hashing and Digital Signatures >> Obfuscation is a process, where you take something that normally would be very easy to understand, and you make

Encryption technologies provide secure key storage, cryptographic functions, and data privacy. In this video, you’ll learn about HSMs, TPMs, secure enclave, and more. << Previous Video: Key Exchange Next Video: Obfuscation >> If you were to look on a modern motherboard, you would find a chip or a subsystem called a Trusted Platform Module, or

A secure key exchange method is critical for real-time encryption. In this video, you’ll learn how a symmetric key can be derived from a public and private key pair. << Previous Video: Encrypting Data Next Video: Encryption Technologies >> As we’ve been discussing in our previous videos, we’ve talked about how important it is to

We use many different encryption techniques to keep our data secure. In this video, you’ll learn about database encryption, transport encryption, cryptographic keys, and more. << Previous Video: Public Key Infrastructure Next Video: Key Exchange >> If you need to protect data that you’re storing on an SSD, a hard drive, or any other type

Public key infrastructure technologies are the foundation of our modern encryption. In this video, you’ll learn about symmetric encryption, asymmetric encryption, key pair generation, and more. << Previous Video: Technical Change Management Next Video: Encrypting Data >> The term public key infrastructure is a very broad term in cryptography, but it commonly refers to policies

A technician is ultimately responsible for putting the change management process into action. In this video, you’ll learn about the technical change management process. << Previous Video: Change Management Next Video: Public Key Infrastructure >> In our previous video, we talked about the change management process. But of course, eventually, the actual change will need

As IT professionals, we are constantly updating, modifying, and changing the devices we manage. In this video, you’ll learn how we manage this process with change management. << Previous Video: Deception and Disruption Next Video: Technical Change Management >> When you’re making a change to an application or an operating system that you use at

There are many ways to fool an attacker into disclosing important information about their methods and techniques. In this video, you’ll learn how to use deception and disruption to protect your network. << Previous Video: Physical Security Next Video: Change Management >> As an IT security professional, you’ll spend a lot of time trying to
