After learning about the different types of cyber-attacks, the textbook introduces security methods that can protect against them. The textbook explains that Two-Factor Authentication (2FA) and Biometric Verification improve security by requiring multiple forms of ID.
These methods add extra layers of protection beyond traditional passwords, making it much harder for attackers to gain unauthorized access.
Definition
Security Methods are techniques and technologies used to protect systems and data from unauthorized access, including Two-Factor Authentication (2FA) and Biometric Verification.
Two-Factor Authentication (2FA) requires two separate factors, like a password and a phone app, to confirm identity.
Biometric Verification uses unique physical features, like fingerprints or face scans, for identification.
In simple words: Security methods are ways to prove who you are before you can access a system. 2FA uses two different proofs; biometrics uses your body (fingerprint, face).
Main Idea
2FA: Requires two different types of proof (something you know + something you have).
Biometric Verification: Uses unique physical characteristics (something you are).
2FA needs two separate factors to confirm identity.
If one factor is breached, the other still offers protection.
Biometric verification uses unique physical features for identification.
It is convenient and tough to fake but may raise privacy issues.
Using both methods together provides strong protection for accessing systems and data.
