General Network Security Mitigation Best Practices
Pure Storage recommends following network security best practices that minimize the risk of compromise:
Restrict management interfaces to a trusted set of networks. Please see Best practices on restricting public IP addresses. Additional security posture hardening may be achieved by restricting all control plane access through a jump box (bastion host).
Restrict outbound Internet access to trusted destinations. Phone Home and Remote Assist (RA) require port 443 (https) to be open to CloudAssist subnet 126.96.36.199/27 for outbound traffic. A firewall will need to permit inbound traffic for the established connection.
Pure Storage strongly encourages the widely-endorsed best practice of highly restricting -- if not blocking altogether -- Internet access to management interfaces, including connections via SSH, TLS, remote consoles, and remote desktop mechanisms.
Closely monitor arrays for abnormal or unexpected workload/ IO spikes or utilization as a leading indicator.
Enable edge detection/protection mechanisms in the firewall / IDS / IPS systems to detect anomalous access or traffic patterns.
