As a technology manager, you handle many tasks that keep your company’s data secure. Two of the most important aspects are understanding authentication factors and ensuring data is encrypted in transit. With this guide, we’ll walk through these concepts in simple terms, explain their importance, and show how they fit into a secure network strategy.
Authentication Factors Explained
When users want to access a system, they need to prove their identity. This process is called authentication. Usually, we categorize authentication into something you know, something you have, and something you are.
- Something You Know: This is the most common type. It involves passwords or PINs that users must remember.
- Something You Have: This could be a smartphone, a security token, or a key card that a user must physically possess.
- Something You Are: These are unique biological features, like fingerprints or facial recognition, that are specific to a person.
Technologies that require more than one of these factors for authentication are called multi-factor authentication (MFA). MFA dramatically increases security because even if one factor is compromised, the others can still protect the data.
Encryption in Transit Basics
Whenever data is sent from one place to another, like when you send an email or browse a website, it travels over the internet. Encryption in transit makes sure that this data is "scrambled"so that anyone trying to intercept it will not understand it without a special key.
