o Where possible, obtain security updates from vendor and apply available
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet .
o Implement firewall rules to block or restrict Internet and intranet access
for database systems.
o Harden internal systems against the potential threat posed by a compromised
system on the local network. (Do not rely on firewalls to prevent access to
insecure systems; secure them).
o Implement firewall rules to block known malicious IP addresses.
