On December 25th, most security engineers find it challenging to explain their jobs to family members due to the complexity of their work in cryptography. To help bridge this gap, an analogy can be drawn between traditional banks and encryption on the internet. Just as big fancy buildings convey trustworthiness for physical banks, TLS certificates serve a similar purpose online by ensuring that users are visiting the actual domain they intend to visit and not a phishing website. Encryption also protects sensitive information from intermediaries during transactions. To stay safe online, individuals should look for encrypted connections, double-check domain names, avoid sharing sensitive information through insecure channels, use different passwords for each account, enable two-factor authentication, and keep their systems updated.
