Phishing continues to be a popular method of network infiltration. In this video, you’ll learn about different phishing techniques, and I’ll demonstrate a real-world example from my email inbox. << Previous Video: Common Threat Vectors Next Video: Impersonation >> Phishing is a term we use to describe social engineering that uses a number of different […]

Attackers can use many different methods to gain access to a system. In this video, you’ll learn how messages, images, files, default credentials, and more can be used as threat vectors. << Previous Video: Threat Actors Next Video: Phishing >> A threat vector is the method that an attacker uses to gain access to your

There are many different types of attackers. In this video, you’ll learn about threat actors from nation states, organized crime, shadow IT, and others. << Previous Video: Certificates Next Video: Common Threat Vectors >> A threat actor is an entity that is the cause of an event that affects the security of others. We often

We use certificates to provide trust when accessing other devices or services. In this video, you’ll learn about digital certificates, certificate signing requests, key revocation, OCSP stapling, and more. << Previous Video: Blockchain Technology Next Video: Threat Actors >> A digital certificate is a file that contains both a public key and a digital signature.

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
