[DR] [PM] Phase 2 IT Disaster Recovery Risk Analysis and Review - Threat Landscape Assessment (Identify)

Building a fortress against IT disasters requires first understanding the potential dangers you face. Phase 2: IT Disaster Recovery Risk Analysis and Review focuses on this crucial first step, Threat Landscape Assessment.

Here, you will identify the potential threats lurking in the ever-evolving IT landscape. This initial phase lays the foundation for a comprehensive DR plan that shields your critical IT infrastructure.

Overview of Threat Landscape Assessment (Identify)

The chapter emphasizes a proactive approach to identifying threats. This includes considering internal threats, such as disgruntled employees or accidental data deletion, and external threats, such as natural disasters, cyberattacks, power outages, or equipment failures. Industry-specific threats are also a consideration, as certain sectors might be more vulnerable to specific attacks. Leveraging industry reports and publications helps you stay updated on the latest cybersecurity threats and emerging attack vectors.

Not all threats are equally likely or damaging. This phase highlights the importance of prioritizing identified threats based on their likelihood and potential impact.

Factors like recent cyberattack trends or historical weather patterns in your region can help assess the likelihood of a threat occurring. The potential impact considers downtime, data loss, financial repercussions, and reputational damage.

By understanding both likelihood and impact, you can effectively prioritize threats, ensuring your DR planning efforts focus on mitigating the risks that pose the greatest danger to your organization.

The chapter concludes by emphasizing the importance of documenting your findings in a Threat Landscape Inventory. This inventory should include a detailed description of each threat, its likelihood of occurring, the potential impact of a successful attack, and any existing controls to mitigate the threat.

By constantly reviewing and updating this inventory, you ensure your DR plan remains aligned with the evolving threat landscape, providing a solid foundation for building a comprehensive and adaptable DR plan.

 Identifying Potential Threats

Just like a house needs a solid foundation to withstand a storm, your DR plan requires a thorough understanding of your IT environment's potential threats.  Here's how to conduct a comprehensive threat landscape assessment:

• Internal Threats. Don't overlook internal risks. Consider accidental data deletion by employees, disgruntled insiders, or even human error during system maintenance.
  
  
• External Threats. The external landscape is vast. This could include natural disasters, cyberattacks (malware, ransomware, phishing), power outages, or equipment failures.
  
  
• Industry-Specific Threats. Specific industries face unique threats. For example, a healthcare organization might be particularly vulnerable to patient data breaches. Identifying these industry-specific risks is crucial.
  
  
• Review Industry Reports. Leverage industry reports and publications to stay updated on the latest cybersecurity threats and emerging attack vectors.

Prioritizing Threats

Not all threats are created equal.  Some pose a higher risk than others.  This phase emphasizes the importance of prioritizing the identified threats based on two key factors:

• Likelihood. How probable is it that a specific threat will occur? Evaluate historical data, industry trends, and your organization's security posture to assess the likelihood of each threat.
  
  
• Impact. If a specific threat were to materialize, what would impact your organization? Consider data loss, downtime, financial repercussions, and reputational damage. By analyzing both likelihood and impact, you can prioritize the threats that pose the most significant risk to your IT infrastructure.
