4. MITIGATIONS

AVEVA recommends organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Users of affected product versions should apply security updates to mitigate the risk of exploit.

• Upgrade to PI Integrator for Business Analytics 2020 R2 SP2 or higher.
• From [OSISoft Customer Portal](PI Integrator for Business Analytics), search for "PI Integrator for Business Analytics" and select version 2020 R2 SP2 or higher.

Additionally, AVEVA recommends the following general defensive measures:

• Audit assigned permissions to ensure that only trusted users are given access rights to publication targets: https://docs.aveva.com/bundle/pi-integrator-for-business-analytics/page/1013185.html
• Ensure publication targets of type Text File or HDFS are configured to limit allowed output file extensions and limit output folders to be logically isolated from critical system components or executable paths:
• https://docs.aveva.com/bundle/pi-integrator-for-business-analytics/page/1023019.html
• https://docs.aveva.com/bundle/pi-integrator-for-business-analytics/page/1023009.html
• Consider applying Windows Defender Application Control (WDAC) to prevent execution of unauthorized executables: https://learn.microsoft.com/en-us/intune/configmgr/protect/deploy-use/use-device-guard-with-configuration-manager

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, 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 these vulnerabilities has been reported to CISA at this time.
