Online Banking Safety Tips for Windows users

  1. “Never use Public Computers and Public WiFi for online banking purpose.”

    I travel for months at a time every year, and I always have to bank online at some point and have never suffered for it. Sure, nothing is 100% and I will agree that it’s safer to do online banking using your or your company’s secure connection… but I think even an open WiFi is “safe enough” — making the author’s blanket warning ‘overblown’? How can I say this?

    People access their banks online using one of two means: browser or bank app.

    1. Browser – Access to any bank account website this day and age is via HTTPS — so data sent is encrypted right before transmission and data received is decrypted right after transmission. Anyone snooping over an unsecured connection will just read gibberish. If HTTPS encryption itself is a security issue, then we have a far, far bigger issue on hand: the entire worldwide web itself!

    2. Bank App – Your bank app is designed to encrypt data similar to (1) above.

    Really, the thing to guard against is “man-in-middle” attack. But that’s a whole different issue because if your device itself is compromised (e.g. keylogger surreptitiously installed), then you may well have a critical security issue where the type of internet connection — secured or not secured — is actually irrelevant. Once the keylogger records (and transmits) the password you had just typed…

    But if I am missing something — that neither HTTPS nor bank apps can help an unsecured WiFi connection, please post.

  2. And, keep away from biometrics if you are security-conscious.

    It is known that the authentication by biometrics usually comes with poorer security than PIN/password-only authentication. The following video explains how biomerics makes a backdoor to password-protected information.
