Black  Friday and Cyber  ​​Monday – these promotional days are particularly attractive for online shoppers because many retailers offer big discounts again.

The Federal Office for Information Security provides tips on how to survive Black Friday and Cyber ​​Monday safely.

Despite all the pre-Christmas love of great bargain hunting, the security of user data should not be forgotten. Otherwise, credit card data is stolen all too quickly, stored payment information is misused or important log-in data is stolen via phishing .

The Federal Office for Information Security ( BSI ) has registered a current spam related to the campaign days and therefore points out the importance of two-factor authentication, which can offer consumers additional protection.

“Even when shopping online, we need to be confident that our account details and other personal information are secure. Two-factor authentication significantly increases the security of customer data, both when registering and when paying via online banking, online payment service or credit card. Whenever sensitive data is involved, online service providers are called upon to offer user-friendly and secure procedures. Consumers should equally insist on using such a procedure. As the national cyber security authority, the BSI digital consumer protection seriously and ensures more cyber security in digitalization, FIDO tokens .

said BSI President Arne Schönbohm.

Two-factor authentication significantly improves the security of log-in procedures. In addition to the combination of user name and password, at least one other factor is used that clearly determines online retailers, banks or social media

These procedures supplement the knowledge factor (password) with the possession factors ( e.g. chip card, TAN generator or certificate) or biometrics ( e.g. fingerprint, iris scan or facial recognition). We explain how this works, what procedures there are and when they can be used sensibly on our consumer portal www.bsi-fuer-buerger.de as well as in the podcast and in our video series “ IT security explained in a understandable way” .

Spam and phishing can generally be recognized very reliably, even by computer laypeople. We explain how this works here . never respond to questionable emails
