Cipher deprecation schedule : How to check if i'm impacted or not

PAVLOVSKY Alexandre

Dear Team & Community,

In order to check if our JIRA will be impacted or not by this TLS cipher depreciation, could you tell me how can i check it?

Do you have any guideline which can explain step by step where and what to check?

 

Thanks a lot in advance for your answer.

According to an Atlassian Team member, the TLS cipher suite change only applies to the incoming mail handler. Incoming emails for our cloud site are delivered to inbound-smtp.us-east-1.amazonaws.com, yours may vary by region.

You can try to enumerate the ciphers supported by that SMTP endpoint with the Linux nmap command:

nmap -sV --script ssl-enum-ciphers -p 587 inbound-smtp.us-east-1.amazonaws.com
