Information security risk assessment is one of the most important parts of business management best practices that aids in identifying, quantifying, and prioritizing of risks in accordance with the objectives and strategic direction of a firm and its risk appetite. Risk management in information security involves identifying, controlling, and reducing the likelihood of incidents that could have negative impacts to an information system resource. This could be subject to parameters such as cost effectiveness, control selection and effectiveness of existing security measures. 

There are some motivations that affect the way people or organizations view the management of information security risks. Utilizing new technology, pushing for innovation, or undercutting costs may force firms to ignore other aspects that have an impact on their reputation and/or stakeholder confidence.  An information security risk assessment’s main goal therefore is to inform the decision-makers on the weaknesses in their business systems so they may take preventative measures and plan effective risk responses that minimise attack surface.

Considerations for Information Security Risk Assessment

To kickstart the risk assessment process, there are at least three questions organizations/people should ask themselves.

  1. What are the critical information assets?
  2. What are the key business processes that utilize/ require these information assets?
  3. What could affect the Confidentiality, Integrity, and Availability of these business functions?

One should think about the risk they are addressing, how high its priority is, and if they are handling it in the most effective way before spending money and/or time implementing a solution to “reduce” risk to an acceptable level.

Information Security Risk Assessment Process

Information security risk assessment is a process used to identify, evaluate, and prioritize potential risks to the confidentiality, integrity, and availability of an organization’s information and information systems. By identifying and analysing these risks, organizations can implement appropriate safeguards to protect against them and ensure the security of their critical assets.

Here is a hypothetical case study to illustrate the process of conducting an information security risk assessment:
Case Study: ABC Corporation

ABC Corporation is a medium-sized manufacturing company that operates in the automotive industry. The company has a large network of computers and servers that are used to store and process sensitive data, including financial information, customer data, and intellectual property.

The management at ABC Corporation has decided to conduct an information security risk assessment to identify and evaluate the potential risks to the company’s information assets. To do this, the company has hired a team of information security professionals to conduct the assessment.

  1. Identifying assets: The first step in the risk assessment process is to identify the assets that need to be protected. This includes not only physical assets such as servers and laptops, but also intangible assets such as sensitive information and intellectual property.
  2. Identify the threats: The next step is to identify the potential threats to these assets. This may include external threats such as hackers, viruses, and malware, as well as internal threats such as employees who may accidentally or intentionally compromise the organization’s information.
  3. Determining vulnerabilities: Once assets have been identified, the next step is to determine the vulnerabilities that could be exploited to compromise those assets. This may include weaknesses in security systems, software vulnerabilities, and other types of vulnerabilities.
  4. Determining the likelihood and impact of risks: Once vulnerabilities have been identified, the next step is to evaluate the likelihood and potential impact of each risk. This allows organizations to prioritize their risk mitigation efforts and focus on the risks that pose the greatest threat to their assets.
  5. Developing risk mitigation strategies: Based on the risk assessment, organizations can develop a plan to mitigate identified risks. This may include implementing new security measures, updating existing measures, or adopting new policies and procedures.
  6. Implementing, monitoring and review of the risk mitigation plan: Once a risk mitigation plan has been developed, it is important to implement it and monitor its effectiveness. This may involve training employees on new security measures, conducting regular security audits, and regularly reviewing and updating the risk assessment as needed.

Why conduct an information security risk assessment?

Conducting information security risk assessments allows organizations to get a holistic view of their environment – from an attacker’s perspective and implement controls to mitigate vulnerabilities domicile in their environment.

The ISO 27005 Standard for Information security assessments, allows organizations to custom make their approach to risk assessment as opposed to a one-size-fits all approach. Some reasons why organizations should conduct information security risk assessments include:

  1. Protect sensitive information: Information security risk assessments help organizations identify and prioritize risks to their sensitive information, such as customer data, financial records, and intellectual property. By identifying these risks and implementing effective risk mitigation strategies, organizations can protect their sensitive information from unauthorized access or disclosure.
  2. Meeting compliance requirements: Many organizations are required to comply with regulations and standards that mandate the protection of sensitive information. Conducting information security risk assessments can help organizations meet these compliance requirements and demonstrate their commitment to protecting sensitive information.
  3. Improve security posture: Information security risk assessments can help organizations identify weaknesses in their security posture and implement measures to improve their overall security. This can include identifying vulnerabilities in software and hardware, implementing stronger passwords and authentication measures, and developing policies and procedures to prevent and respond to security breaches.
  4. Protect against cyber-attacks: Cyber-attacks and data breaches can have significant financial and reputational consequences for organizations. By conducting information security risk assessments, organizations can identify and prioritize the risks of cyber-attacks and implement measures to prevent or mitigate these attacks.
  5. Reduce risk of legal liabilities: Failing to protect sensitive information can result in legal liabilities for organizations, such as fines and lawsuits. Conducting information security risk assessments can help organizations reduce the risk of legal liabilities by identifying and mitigating risks to sensitive information.
  6. Protect brand reputation: A security breach can also damage an organization’s reputation and credibility. By conducting an information security risk assessment and implementing effective risk mitigation strategies, organizations can protect their reputation and maintain the trust of their customers and stakeholders.
  7. Avoid financial losses: A security breach can result in financial losses for an organization, including the cost of responding to the breach, repairing any damage, and potentially paying fines or legal settlements. Conducting an information security risk assessment can help organizations identify and prioritize risks and implement strategies to prevent such losses.


Effective information security risk assessment is an ongoing process that requires regular review and updating to ensure the ongoing protection of an organization’s assets. By identifying and prioritizing potential risks, organizations can implement appropriate safeguards to mitigate those risks and ensure the security and integrity of their critical information and systems.
