Disable/Remove ArcFour stream cipher from PCA management nodes

in Oracle Private Cloud Appliance (PCA) (MOSC) 2 commentsAnswered ✓

Hi,

During a recent vulnerability scan by our client on their PCA v2.4.2, they discovered that management nodes are allowing ArcFour stream ciphers. Recommended action is to block/prevent this cipher by editing the /etc/ssh/sshd_config file.

Is there any impact to block/prevent this cipher? My concern is PCA is an enginereed hardware, and I am not sure if there is any factory pre-configured services or components which requires this cipher to function properly.

Appreciate your inputs.

Thank you.

Howdy, Stranger!
