A cybersecurity interview preparation post containing 15 sample questions and answers covering fundamental concepts like the CIA Triad, threat vs. vulnerability vs. risk, authentication vs. authorization, incident response, encryption types, and security tools.
A tech expert explains how passkeys work: devices use 256-bit cryptographic key pairs where private keys stay local and public keys authenticate on servers, making passkeys phishing-resistant since domain information is embedded in the cryptographic handshake. According to Google's production data, passkey-protected accounts have virtually zero account-takeover incidents compared to 88% of web breaches involving stolen passwords in 2025.
