Whether it’s cloud, multi-cloud, or hybrid cloud, there is no end to cyber risk. So, organizations must be confident in their ability to protect their cloud environments and prepare for emergency scenarios. In most cases, this preparation comes in the form of hardening your cybersecurity defenses and becoming cyber resilient by adopting the technologies, processes, and expert-level support.

While many business leaders verbally declare the importance of reducing cyber risk, only a few understand that there are varying approaches to managing cyber risk – some far more successful than others.

In this webinar, eSentire’s Vice President, Cyber Risk Advisory and Solutions Architecture, Tia Hopkins briefs Cloud Security Alliance (CSA) members on the challenges of maturity-based security programming and outline how leveraging security operations and incident response can help organizations transition to a risk-based approach that enables true quantification of cyber risk in the cloud.

Key Takeaways:

  • Evolution of security management - Actively manage your cloud security posture
  • Risk management vs risk reduction - Stop attackers and mitigate risk
  • Challenges with assessing risk - Detect emerging threat tactics
