Three Greatest SIEM Obstacles in Multi-Cloud Environments

Security information and event management (SIEM) combines the most beneficial aspects of security information management (SIM) and security event management (SEM) to provide a unified platform for intrusion detection and response. Even though SIEMs have traditionally lacked preventative capabilities, users are increasingly expecting SIEMs to meet this use case as part of tool consolidation. As a result, we must transition from reactive security to proactive security, preventing breaches before they occur.

The transition to the cloud exacerbates the visibility issues of perimeter-based detection and response systems, mandating the agility and power of a separate solution class. The SOC can regain operational awareness and control with SIEM. To be successful with this attempt, you must consider the following cloud dynamics:

  • Compatibility
  • Scalability
  • SIEM learning curve

Multi-Cloud SIEM Compatibility

A SIEM must be compatible with your present environment, including your cloud infrastructure and apps, and allow future growth for it to be effective. Sadly, most SIEMs need to be more capable of offering out-of-the-box threat detection and response across cloud technologies. In addition, a multi-cloud SIEM must be able to process cloud data out of the box and normalize it into a standard, understandable format.

Critical is the automatic detection of threat signs leveraging native cloud data types. However, organizations need more time and resources to set up and configure the SIEM and develop environment-specific attack detection signatures.

Multi-Cloud SIEM Data Is Highly Scalable

Cloud data is intrinsically diverse in structure, has a high information throughput rate, and continues to grow exponentially as cloud infrastructure and applications proliferate. Traditional SIEMs are designed for security using conventional data sources, including system and firewall logs. While some vendors may adapt current SIEMs to analyze cloud data, the interface between the cloud and traditional data from servers and network devices is sometimes clean or functional.

Scalability becomes a formidable obstacle for SIEMs not optimized for cloud data, especially in multi-cloud environments. Without normalization, the different formats pose a data processing challenge at scale. In addition, the high-velocity, temporary nature of this massive-scale cloud architecture means that an instance of a cloud application may have been created, destroyed, and possibly recreated by the time an analyst receives an alert. Because there may be no logs to review after an incident happens, the SIEM must be able to collect all relevant data in real time.

The SIEM Cloud Security Learning Curve

For many businesses, cloud security is a novel idea, and processing cloud security data through a SIEM can be complex. Cloud security indications and events do not resemble traditional security indicators. SIEMs that do not normalize this data into a more understandable format is highly burdensome and challenging.

Unfortunately, the learning curve for many SIEMs is steep, and there needs to be a user community to provide mutual help. With this help, the SIEM deployment schedule will be brief, and so will the onboarding of additional security analysts. Add to this the intricacy of cloud data; even the most seasoned cybersecurity analyst may need help to analyze these data independently.

Conclusion

The SIEM difficulties, such as multi-cloud compatibility, data complexity, scalability, and the learning curve for processing cloud data with a SIEM, must be considered. These are difficult obstacles that only some SIEMs can overcome, especially when considering the velocity of cloud data and the rapid creation and destruction of dynamic cloud instances.
