Ideas this quiz checks
Phishing
Phishing is a social engineering attack where cybercriminals impersonate trusted entities (banks, tech companies, colleagues) via email, text, or fake websites to trick victims into reveali…
Why is reusing the same password across multiple accounts dangerous
Password reuse is dangerous because of 'credential stuffing' attacks.
What does two-factor authentication (2FA) add to the login process
Two-factor authentication adds a second layer of security beyond your password.
Purpose of HTTPS in web browsing
HTTPS (HyperText Transfer Protocol Secure) encrypts the data transmitted between your browser and a website using TLS (Transport Layer Security).
Zero-day vulnerability
A zero-day vulnerability is a software security flaw that is unknown to the software vendor and therefore has no available patch or fix.
Ransomware
Ransomware is malicious software that encrypts the files on a victim's device or network and then demands a ransom payment (often in cryptocurrency) in exchange for the decryption key.
