What is ISO 27005? 

ISO 27005 is a globally recognized standard that provides a systematic approach to help manage the security risks of a company. It serves as a framework for organizations to identify, assess, and mitigate potential threats to their information assets from cyberattacks and cybercrimes.  

ISO 27005 standards are recommended for private and public establishments, including government agencies and NGOs (non-profit organizations). This security standard ensures data confidentiality, availability, and integrity of an organization’s assets.  

Requirements of ISO 27005 

To adhere to ISO 27005 standards, organizations must follow a structured approach that includes: 

• Risk Assessment: An organization needs to conduct regular risk assessments to help them identify potential threats, vulnerabilities, and impacts on information assets. 
• Risk Analysis: Once the risks have been identified, organizations further analyze them to establish their potential impact on business operations. 
• Risk Evaluation: Risks are then evaluated based on some predetermined criteria and then prioritized for treatment. 
• Risk Treatment: The prioritized risks need to undergo risk treatment plans to mitigate, transfer, or accept risks. 
• Risk Monitoring and Review: Continuous monitoring and review of risk management processes ensure the effectiveness of the risk management plan while ascertaining adaptability to evolving threats and organizational changes.  

Pros of ISO 27005 

Some of the most significant benefits of ISO 27005 are:

Cons of ISO 27005 

Despite its numerous advantages, ISO 27005 has also some limitations. Here are some drawbacks to consider: 

• Implementation Complexity: Implementing this standard can be complex for some. As it requires specialized knowledge and expertise, resource-constrained organizations may find it difficult to implement ISO 27005 effectively. 
• Subjectivity in Risk Assessment: Risk assessment involves subjective judgments, which often lead to potential inconsistencies. The interpretations of risks vary depending on the perspectives and therefore make ISO 27005 challenging.  
• Resource Requirements: Conducting thorough risk assessments demands significant time, effort, and financial resources as well. This is why organizations with budget constraints and manpower may find ISO 27005 difficult to implement.
