Multifactor authentication (MFA) is a security measure that requires users to provide multiple pieces of evidence when logging in to an account or system. This can include a combination of something the user knows (e.g. a password or PIN), something the user has (e.g. a security token or smartphone) and something the user is (e.g. biometrics such as a fingerprint or face scan). By enabling MFA, the systems administrator can ensure that users are required to provide multiple pieces of evidence when logging in, making it more difficult for unauthorized users to gain access to the system. This can help reduce the number of help desk tickets submitted due to forgotten passwords.

Encryption is a way of protecting cardholder data by transforming it into an unreadable format that can only be decrypted with a secret key1. Backups are a way of ensuring that cardholder data is not lost or corrupted in case of a disaster or system failure2. Both encryption and backups are part of the PCI DSS requirements that apply to any entity that stores, processes, or transmits cardholder data1. The other options are not directly related to credit card data security or compliance.

The most effective method for dealing with spam messages in a small business is to provide user training1. Users should be trained to recognize spam messages and avoid opening them1. They should also be trained to report spam messages to the IT department so that appropriate action can be taken1. In addition, users should be trained to avoid clicking on links or downloading attachments from unknown sources1. By providing user training, the management team can reduce the risk of users opening spam messages and potentially infecting the network systems1.
