PREPARE:

Minimizing vulnerabilities within your organization reduces the opportunities for attackers to successfully breach your network, and therefore, reduces the risk of compromise and data loss. We recommend that organizations consider the steps below to identify possible threats:

  • Review the CISA briefing and determine if you have any vulnerable technology on your estate.

  • Update and patch software promptly wherever possible to reduce the availability of security weaknesses.

  • Utilize multi-factor authentication wherever available.

  • Block obsolete or unused network protocols at the network perimeter.

  • Collect and monitor logs from perimeter devices.


RESPOND:

ORNA provides organizations with a clear, step-by-step guide for how to respond in the event of a cyber attack supported, if needed, by our incident response experts.


In addition, ORNA's Alerts module allows organizations to monitor assets and provides alerts enriched with deep insight including tools, tactics, procedures, and indicators of compromise, allowing you to promptly identify and respond to potential network threats.
