A regional water utility has a small ICS security team. They receive a vendor advisory about a vulnerability in their SCADA HMI, but the advisory lacks specific indicators. The team wants to enrich this with actionable IOCs. Which source should they prioritize to obtain indicators specific to their sector?

A social media feed from a security researcher

A general-purpose cybersecurity news website

A security analyst notices that an adversary has been probing the corporate network for VPN credentials and has also sent spear-phishing emails to engineers who have remote access to the ICS.

A detailed technical report with IOCs and TTPs

A concise operational alert with clear actions

An ICS security team is implementing the threat intelligence lifecycle. They have completed the direction and collection phases and are now processing the data. However, they are overwhelmed by the volume of raw data and are struggling to identify relevant intelligence. What is the most effective way to address this challenge?

Disseminate the raw data to stakeholders to let them analyze it

Skip the processing phase and analyze raw data directly

Automate the processing phase to normalize and deduplicate data before analysis

Collect less data to reduce the volume
