The Problem with Legacy Security
For years, businesses have placed their trust in legacy systems that rely on constant kernel updates to manage security. These models are no longer capable of addressing today’s advanced threats. Two major risks arise from this architecture:
- Security Posture: Legacy systems operate on a “default allow” principle, allowing new, undetected adversaries to infiltrate networks and systems.
- System Safety: Continuous kernel updates introduce unvalidated content, putting enterprises at constant risk of instability and outages, as seen in the CrowdStrike case.
At Cyber Strategy Institute, we know there’s a better way forward.
The Zero Trust Paradigm
Zero Trust is the answer. Unlike legacy models, Zero Trust doesn’t allow any action without verification. This approach ensures:
- Superior Security: Every access request is thoroughly validated, significantly reducing risks posed by undetected threats.
- Enhanced Safety: Without the need for constant kernel updates, Zero Trust dramatically improves system stability and availability, protecting enterprises from potential downtimes.
