Securing hybrid and multi-cloud environments is becoming an increasingly complex task. The integration of LogRhythm and Exabeam provides a comprehensive solution for effectively protecting both cloud and on-premise infrastructure, ensuring end-to-end visibility and control.

Challenges of Hybrid Security

Hybrid security is a complex mosaic where fragments of cloud and on-premise infrastructures are intertwined, creating unique challenges for cybersecurity professionals. In the face of rapid growth of multi-cloud environments, organizations face a number of serious problems requiring a comprehensive and strategic approach.

Disparate Tools and Data Sources

One of the key challenges is the fragmentation of tools and data sources. Cloud environments use one set of monitoring and protection tools, while on-premise infrastructure uses another. This leads to gaps in visibility and hinders the correlation of events between different network segments. Security information is scattered across multiple systems, which significantly complicates incident detection and investigation.

Complexity of Monitoring and Event Correlation

Effective monitoring and correlation of events in a hybrid environment requires significant effort and resources. Analyzing logs and events generated by various systems becomes a laborious and time-consuming process. The lack of a unified platform for data collection and analysis means that many potential threats go unnoticed. Monitoring hybrid environments must be comprehensive to cover both classic infrastructure and dynamic cloud services.

Insufficient Visibility of Attacks

Attacks spreading between cloud and on-premise infrastructure pose a particular danger. Attackers can exploit vulnerabilities in one environment to penetrate another, bypassing traditional defenses. The lack of end-to-end visibility and control makes such attacks difficult to detect and leads to serious consequences. It is important to be able to track the movement of data and user activity throughout the hybrid infrastructure.

Configuration Risks and Compliance

Maintaining compliance with regulatory requirements in a hybrid environment is another complex task. Different cloud platforms and on-premise systems have their own unique configuration and security requirements. Ensuring compliance with these requirements requires significant effort and expertise. Incorrect configurations and misconfigurations can lead to serious vulnerabilities and violations of regulatory requirements, leading to financial and reputational risks.
