Not all information security risks translate directly to business risks

There is a misconception among security professionals: the belief that all information security risks will result in significant business risks. This perspective is misleading because not every information security incident has a severe impact on an organization’s bottom line. Business decision-makers can become desensitized to security alerts if they are inundated with generalized statements, leading them to ignore real risks. Thus, it is essential for security experts to present nuanced, precise analyses that distinguish between minor and significant threats to maintain credibility and ensure their assessments are taken seriously.

There are two types of risks:

  1. Information Security Risk: This occurs when a threat (e.g., a virus) encounters a vulnerability (e.g., lack of antivirus protection), potentially compromising confidentiality, availability, or integrity of information. Depending on the severity, it can range from a minor issue, like a temporary power outage, to a critical breach, such as theft of sensitive data.
  2. Business Risk: This affects the organization’s financial stability, compelling decision-makers to act. It can manifest as lost revenue, increased costs (e.g., penalties), or reputational damage, especially if regulatory fines are involved.

Not all information security risks translate directly to business risks. For example, ISO27001 emphasizes calculating the Annual Loss Expectation (ALE) and suggests that risks should only be addressed if their ALE exceeds the organization’s acceptable threshold.

Example:

Small Business Data Breach: A small Apple repair company faced internal sabotage when a disgruntled employee reformatted all administrative systems, erasing customer records. The company managed to recover by restoring data from backups and keeping customer communication open. Despite the breach’s severity, the company retained its customers, and the incident was contained. This case underscores the importance of adequate data management and disaster recovery planning.

Several factors to consider when assessing the relationship between information security and business risk:

  • Business Model: Certain businesses can withstand breaches with minimal financial impact, while others (e.g., payment processors) face more significant risks.
  • Legal Impact: Fines and legal costs can sometimes outweigh the direct costs of a breach. Organizations must assess regulatory requirements and contractual obligations to understand potential legal implications.
  • Direct Financial Impact: While breaches can lead to financial loss, this is sometimes treated as a routine cost of doing business, akin to paying for regular IT services.
  • Affected Stakeholders: It is crucial to identify which parties will bear the brunt of the damage. In some cases, third parties, like investors, may suffer more than the organization experiencing the breach.

Ultimately, information security risks must be evaluated within the broader business context. A comprehensive understanding of the company’s environment, stakeholders, and industry will help in prioritizing actions and reducing overall breach costs.
