In today’s cybersecurity landscape, vendor lock-in with Security Information and Event Management (SIEM) solutions is a common challenge. Organizations often depend on a single vendor’s proprietary tools, data formats, and workflows, limiting flexibility and increasing costs.

Two powerful strategies have emerged to overcome this: multi-SIEM and hyper-automation. While each approach offers unique benefits, combining them creates a robust solution to counter SIEM lock-in effectively.

Understanding SIEM Lock-In

SIEM lock-in occurs when organizations rely heavily on one vendor’s platform for security operations. This dependency can arise due to:

• Proprietary Data Formats: Unique schemas that complicate migration.
• Custom Integrations: Vendor-specific workflows tied to APIs.
• Long-Term Contracts: High termination fees or penalties.
• Skill Specialization: Teams trained exclusively on one platform.

This lock-in restricts flexibility, inflates costs, and limits the ability to adopt innovative tools and technologies.

Multi-SIEM: Diversifying Platforms for Flexibility

A multi-SIEM strategy involves using multiple SIEM platforms simultaneously to avoid dependency on a single vendor. This approach enables organizations to leverage the strengths of various tools while maintaining operational flexibility.

Benefits of Multi-SIEM:

1. Avoid Vendor Dependency: Diversifying across platforms reduces reliance on proprietary systems.
2. Combine the Strengths of Multiple Tools: For example, Splunk excels at analytics, while Microsoft Sentinel offers cloud-native monitoring capabilities.
3. Facilitate Migration: Enables parallel operations during transitions between SIEMs, minimizing disruptions.
4. Cost Optimization: Allows organizations to use cost-effective solutions for specific needs, such as Elastic for log storage and QRadar for compliance reporting.

Challenges of Multi-SIEM:

• Operational Complexity: Managing multiple SIEMs requires additional resources and expertise.
• Integration Overhead: Ensuring seamless data flow between platforms can be challenging without automation tools.

Hyper automation: Streamlining Operations Across Platforms

Hyper automation leverages AI, machine learning (ML), and robotic process automation (RPA) to automate workflows across tools, including SIEMs. It enhances efficiency by reducing manual tasks and enabling intelligent decision-making across platforms.

Benefits of Hyperautomation:

1. Vendor-Agnostic Workflows: Automates processes across multiple SIEMs and other security tools, breaking the reliance on a single vendor’s ecosystem
2. Standardized Data Handling: Uses frameworks like Open Cybersecurity Schema Framework (OCSF) to normalize data across platforms
3. Simplifies Migration: Automates data mapping and workflow replication during transitions from one SIEM to another
4. Reduces Manual Effort: Automates repetitive tasks like alert triage, threat investigation, and compliance reporting
5. Accelerates Incident Response: AI-driven automation enables real-time threat detection and response across hybrid environments

Challenges of Hyperautomation:

• Requires integration with existing tools and systems for optimal performance

Why Multi-SIEM and Hyperautomation Work Best Together

While both strategies offer individual benefits, combining them creates a powerful synergy:

1. Enhanced Threat Detection Across Platforms

Multi-SIEM environments allow organizations to leverage the strengths of different platforms for comprehensive threat detection. Hyperautomation further enhances this by automating event correlation across disparate systems, enabling faster identification of complex attack patterns that might go unnoticed in isolated systems.

2. Centralized Data Management

Hyperautomation consolidates data from multiple SIEMs into a centralized repository or logical layer, reducing fragmentation. This centralization speeds up incident investigation and response while improving overall visibility into the security landscape.

3. Reduced Alert Fatigue

Multi-SIEM environments often inundate analysts with alerts from multiple platforms, leading to fatigue. Hyperautomation addresses this by filtering false positives using advanced analytics and machine learning models, allowing analysts to focus on critical incidents.

4. Cost Efficiency

Multi-SIEM optimizes cost by pairing expensive tools with cost-effective alternatives for specific use cases. Hyperautomation reduces operational costs by automating repetitive tasks and improving resource allocation.

5. Seamless Migration Between SIEMs

Combining multi-SIEM with hyper-automation simplifies migration efforts by automating data mapping and workflow replication while maintaining operational continuity during transitions.

Conclusion: The Best Solution to Counter SIEM Lock-In

To effectively overcome SIEM lock-in situations, organizations should adopt a hybrid approach that combines the strengths of both multi-SIEM and hyper-automation:

• Use multi-SIEM strategies to diversify tools and reduce vendor dependency.
• Leverage hyper-automation to streamline operations, automate platform workflows, and enhance threat detection capabilities.

This combination ensures flexibility while maintaining operational efficiency in an increasingly complex cybersecurity landscape.

The Reserve Bank of India (RBI) aims to strengthen the digital defenses of Indian urban cooperative banks (UCBs). The “Comprehensive Cyber Security Framework for Primary (Urban) Cooperative Banks (UCBs),” issued on December 31, 2019, marks a crucial step using a graded approach. This thoughtful approach tailors security requirements to each UCB’s unique digital footprint.

Why a Graded Approach?

One size doesn’t fit all! The RBI understands that cyber security needs vary greatly. By categorizing UCBs into levels, the framework ensures proportionate security measures are implemented. Smaller UCBs focus on essential security, while larger ones adopt more robust controls.

Understanding the Four Levels & Key Controls:

The framework organizes UCBs into four distinct levels, each with specific requirements. Here’s a breakdown:

Delving Deeper: A Summary of the Annexures:

To better understand the scope of each UCB, below are the expectations for the framework’s annexes:

• Annex I (Level I – Baseline Security): Sets the foundation with basic cyber hygiene. Think secure email with DMARC implementation and 2FA for Core Banking System (CBS) access. Key Takeaway: EVERY UCB MUST implement these fundamental security controls.
• Annex II (Level II—Enhanced Security): This adds to Level I and emphasizes network security, secure configurations, application security (secure code review, pen testing), and data leak prevention. It is for UCBs with more digital exposure.
• Annex III (Level III—Cyber Security Controls): This section targets UCBs directly involved in payment systems. Its focus is on advanced threat management, emphasizing real-time threat defense and risk-based transaction monitoring (RBTM) to detect and prevent fraud.
• Annex IV (Level IV – IT and IS Governance Framework & Setting Up of Cyber Security Operation Centre (C-SOC)): Provides comprehensive guidance for establishing a strong IT and IS governance framework and setting up a C-SOC. The focus is on UCBs with a high digital infrastructure and interconnectivity level.

Key Responsibilities & Expectations:

• Board-Level Accountability: The Board is ultimately responsible for information security and must champion IT and IS governance.
• Self-assessment is MANDATORY: UCBs must accurately self-assess their level and report it to the RBI.
• Phased Implementation: Adhere to the timeframes for implementing controls at each level.
• Vendor Risk Management: You’re responsible for your vendors’ security.

What This Means for UCBs: Take Action!

This RBI framework is a vital step towards strengthening the cyber resilience of the cooperative banking sector. UCBs must take proactive steps to:

1. Determine their Level: Conduct a thorough self-assessment.
2. Implement Controls: Meet all security control requirements within the specified timeframes.
3. Strengthen Governance: Enhance IT and IS governance practices.
4. Train Employees: Provide ongoing cyber security awareness training.
