Question
A web application server that provides services to hybrid modern and legacy financial applications recently underwent a scheduled upgrade to update common libraries, including OpenSSL. Multiple users are now reporting failed connection attempts to the server. The technician performing initial triage identified the following:
- Client applications more than five years old appear to be the most
affected.
- Web server logs show initial connection attempts by affected hosts.
- For the failed connections, logs indicate "cipher unavailable."
Which of the following is most likely to safely remediate this situation?
Options
- AThe server needs to be configured for backward compatibility to SSL 3.0 applications.
- BThe client applications need to be modified to support AES in Galois/Counter Mode or equivalent.
- CThe client TLS configuration must be set to enforce electronic codebook modes of operation.
- DThe server-side digital signature algorithm needs to be modified to support elliptic curve
