Observability has become a crucial trend in technology, enabling organizations to monitor and analyze the performance of their systems, while also factoring in cyber resiliency. The article explores the connection between observability and cyber resiliency, emphasizing the importance of log data in identifying and diagnosing security breaches, as well as the need for secure and prolonged log retention to detect potential threats. It highlights practices such as log air-gapping and immutability to enhance security and prevent tampering. The article also addresses the rise in DDoS attacks and the role of observability platforms like Coralogix, which leverage integrations with services like Cloudflare to provide early warnings and mitigate such threats. Additionally, it underscores the advantage of AI-powered tools for establishing baselines of normal system behavior, which help detect anomalies that could indicate security issues. By implementing comprehensive observability and leveraging AI insights, organizations can better ensure cyber resiliency and respond effectively to potential threats.
