 * Aligning with CISA recommendations, Johnson Controls recommends taking steps
   to minimize risks to all building automation systems.

CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability, such as:

 * Minimize network exposure for all control system devices and/or systems,
   ensuring they are not accessible from the internet.
 * Locate control system networks and remote devices behind firewalls and
   isolating them from business networks.
 * When remote access is required, use more secure methods, such as Virtual
   Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should
   be updated to the most current version available. Also recognize VPN is only
   as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment
prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices
on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber
defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies
for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics in the technical information paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies.

Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.

CISA also recommends users take the following measures to protect themselves
from social engineering attacks:

 * Do not click web links or open attachments in unsolicited email messages.
 * Refer to Recognizing and Avoiding Email Scams for more information on
   avoiding email scams.
 * Refer to Avoiding Social Engineering and Phishing Attacks for more
   information on social engineering attacks.

No known public exploitation specifically targeting this vulnerability has been
reported to CISA at this time.
