How you can protect critical systems and avoid serious IT failures through IT architecture and system assessment

On July 5, 2024, a major IT outage caused by a CrowdStrike-Falcon heuristics update caused significant disruption to Windows environments worldwide. This disruption affected key industries, including airlines and retailers, resulting in canceled flights and disrupted operations worldwide. Affected companies reported massive operational failures that significantly impacted their daily business activities.

The importance of IT security and strategy consulting

Incidents such as the CrowdStrike outage underline the complexity of modern IT infrastructures and the need for a holistic, systematic approach to IT security and strategy. At integrationWorks, we take a comprehensive approach that aims to strengthen the resilience of your IT infrastructure and minimize potential failure risks.

Our focus is on developing robust architectures and processes that enable organizations to deal with the inherent risks and challenges of modern IT environments. We recognize that no single solution or technology can provide a guarantee against all possible problems. Instead, we work to create systems that are flexible, resilient and adaptable.

Comprehensive security assessments and architectural planning

Our security assessments and architecture planning begin with a deep understanding of our clients' business goals and strategies. We recognize that every IT solution must ultimately serve business needs. Our holistic approach includes:

1. Analyzing the business strategy and objectives

   • Understanding the short and long-term business goals

   • Identifying critical business processes and their IT dependencies

   • Assessment of growth plans and scalability requirements

2. Inventory of the existing IT infrastructure

   • Identify critical systems and dependencies

   • Assessment of potential vulnerabilities and risks

   • Review of security architecture and processes

3. Alignment of IT and business requirements

   • Alignment of IT capacities with business requirements

   • Identification of gaps between IT capabilities and business objectives

   • Prioritization of IT initiatives based on business relevance

4. Future-oriented architecture planning

   • Designing a target architecture that supports business growth and innovation

   • Consideration of industry trends and technological developments

   • Planning for flexibility and adaptability in the architecture

5. Security and compliance integration

   • Embedding security measures into the architecture from the ground up

   • Consideration of industry-specific compliance requirements

   • Development of security policies that support, not hinder, business processes

6. Cost-benefit analysis

   • Evaluating the return on investment (ROI) for proposed architectural changes

   • Balancing security, performance and cost efficiency

Based on these comprehensive findings, we develop customized architecture and security roadmaps. These provide a structured, phased plan for improving the overall architecture, implementing robust processes and integrating solutions that both increase overall system resilience and optimally support business objectives.

Our goal is to create an IT architecture that is not only secure and resilient, but also acts as a strategic enabler for the business. By closely aligning IT architecture and business strategy, we ensure that investments in IT infrastructure contribute directly to the achievement of corporate goals and create measurable added value for the business.

Redundancy and reliability

The implementation of redundancy and resilience is crucial for the continuity of critical business processes. Our approach takes into account the specific requirements and priorities of each company:

1. Business criticality analysis

   • Definition of recovery time objectives (RTO) and recovery point objectives (RPO)

2. Customized redundancy strategies

   • Design of high-availability architectures based on business requirements

   • Implementation of load balancing and failover mechanisms

   • Geographically distributed systems to minimize risk while taking location strategies into account

3. Continuous availability testing

   • Regular testing of failover systems and processes

   • Simulation of failure scenarios to validate business continuity

   • Adaptation of strategies based on test results and changing business requirements

4. Cost-efficient redundancy solutions

   • Balancing redundancy level and cost efficiency

   • Utilizing cloud technologies for flexible and scalable redundancy solutions

   • Optimizing the use of resources in redundant systems

This holistic approach ensures that redundancy and resilience strategies are optimally aligned with the company's business objectives and risk appetite.

Backup and disaster recovery

A robust backup and disaster recovery system is essential for protecting business-critical data and ensuring business continuity. Our approach includes:

1. Business impact analysis

   • Identification of critical data and systems based on business relevance

   • Establishing recovery priorities in alignment with business objectives

   • Definition of data retention policies taking into account legal and business requirements

2. Multi-layered backup strategy

   • Implementation of a backup concept, e.g. 3-2-1 backup (3 copies, 2 media, 1 off-site)

   • Setting up off-site and offline backups to protect against ransomware

   • Use of cloud technologies for scalable and cost-efficient backup solutions

3. Comprehensive disaster recovery planning

   • Development of detailed disaster recovery plans tailored to business processes

   • Regular testing and updating of disaster recovery procedures

   • Training IT staff and relevant business units in disaster recovery procedures

4. Automation and optimization

   • Implementation of automated backup and recovery processes

   • Continuous monitoring and optimization of backup performance

   • Regular review and adaptation of strategies to changing business requirements

5. Compliance and governance

   • Ensuring adherence to industry-specific compliance requirements

   • Implementation of audit trails and reporting mechanisms

   • Regularly reviewing and adapting strategies to changing legal requirements

Through this comprehensive approach, we ensure that companies remain capable of acting even in the event of unforeseen events and can quickly restore critical business processes, always focusing on the specific business requirements.

Optimization of the system architecture

An optimized system architecture forms the foundation for efficient, secure and future-oriented IT operations. Our approach to architecture optimization includes

1. Business-oriented architecture analysis
