Which of the following statements best describes the use of 'early TLS'?

• A. It may be used for POS POI connections only if verified not susceptible to known exploits.
• B. It should never be used.
• C. It is the preferred modern standard.
• D. It has no security implications.

Answer: (A)

Early TLS refers to older TLS versions (and SSL) that have known weaknesses. The safest stance is to avoid them, but there is a narrow exception: for POS POI connections, you may tolerate early TLS only if you can verify that the specific devices are not susceptible to known exploits and you have appropriate compensating controls in place. This captures the idea of a tightly limited allowance rather than a blanket rule. The other statements are not accurate: early TLS isn’t considered a modern, preferred standard, and it does carry security implications, so saying it should never be used or that it has no security impact would be misleading.
