Online Security Risk Assessment The Key to Protecting Your Organization


Online security risk assessments are crucial for effective cybersecurity and information security risk management in organisations today. By identifying potential threats to your IT systems, data, and other resources, as well as understanding their potential business impacts, you can prioritise your mitigation efforts to prevent costly disruptions, data breaches, compliance penalties, and other damages.

In this comprehensive guide, we will explain what an online security risk assessment is, the benefits of conducting regular assessments, and the step-by-step process involved in conducting an assessment.

What is an Online Security Risk Assessment?

An online security risk assessment is a systematic process of identifying vulnerabilities in the IT ecosystem and understanding the financial threat they pose to an organisation. It involves evaluating the risks associated with potential threats, from downtime and profit loss to legal fees and compliance penalties, in order to prioritise security efforts as part of a broader cybersecurity program.

It is important to note that an online security risk assessment is just one component of a broader IT risk assessment process. IT risk assessments consider a range of cyber risks beyond cybersecurity. These can include data exfiltration, compromised credentials, phishing attacks, denial of service (DoS) attacks, supply chain attacks, misconfigured settings, hardware failures, natural disasters, and human errors.

Benefits of Online Security Risk Assessments

Conducting regular online security risk assessments provides significant value to organisations. Some key benefits include:

  1. Insight into valuable IT assets: By conducting an assessment, you gain a clear understanding of where your most valuable IT assets reside. This knowledge is crucial for prioritising security efforts and ensures that you allocate resources effectively.
  2. Understanding of risks: A thorough assessment helps you identify and analyse potential threats to your business. This enables you to focus on the risks that have the highest potential impact and probability, allowing for more efficient risk management.
  3. Vulnerability identification and remediation: An online security risk assessment methodology helps you identify and address vulnerabilities that threat actors can exploit. Examples of vulnerabilities include unpatched software, overly permissive access policies, and unencrypted data. By closing these gaps, you can significantly reduce your organisation’s overall risk exposure.
  4. Cost mitigation: Conducting an online security risk assessment not only safeguards your business from the high cost of a data breach, but it also enables you to allocate your security budget more effectively. By identifying and prioritising risks, you can invest in security initiatives that deliver the most value and mitigate potential financial losses.
  5. Regulatory compliance: Regular security risk assessments help organisations comply with data security requirements mandated by regulations such as HIPAA, PCI DSS, SOX, and GDPR. By meeting these requirements, you can avoid costly fines and penalties.
  6. Improved customer trust: Demonstrating a commitment to security through regular risk assessments can increase customer trust. This can lead to improved client retention and a competitive advantage in the market.
  7. Informed decision-making: Detailed insights provided by an online security risk assessment facilitate better decision-making regarding security, infrastructure, and personnel investments. This enables organisations to make informed choices that align with their overall risk management strategy.

Steps in an Online Security Risk Assessment

Now, let’s explore the step-by-step process involved in conducting an online security risk assessment:

Step 1: Identify and Prioritise IT Assets

  1. Identify all IT assets within your organisation, including servers, printers, laptops, and other devices.
  2. Solicit input from all departments and business units to ensure a comprehensive understanding of the systems and data the organisation uses and collects.
  3. Determine the importance of each asset based on criteria such as monetary value, role in critical processes, and legal and compliance standing.
  4. Classify your assets into categories, such as critical, major, or minor, based on their importance to the organisation.

Step 2: Identify Threats

  1. Identify potential threats that could cause harm to your organisation.
  2. Examples of threats include outside threat actors, malware, malicious acts by business users, and mistakes by insufficiently trained administrators.

Step 3: Identify Vulnerabilities

  1. Identify vulnerabilities within your IT infrastructure that could be exploited by threats.
  2. Utilise analysis, audit reports, vulnerability databases, vendor data, security test and evaluation procedures, penetration testing, and automated vulnerability scanning tools to identify vulnerabilities.

Step 4: Analyse Existing Controls

  1. Analyse the controls currently in place to reduce the probability of threats exploiting vulnerabilities.
  2. Examples of controls include encryption, intrusion detection systems, multifactor authentication, security policies, administrative procedures, and physical or environmental protections.
  3. Categorise controls as preventive or detective, depending on whether they are designed to thwart attacks or identify ongoing threats.

Step 5: Determine the Likelihood of an Incident

  1. Assess the probability that each vulnerability might be exploited by considering factors such as the nature of the vulnerability, the intent and capacity of the threat source, and the effectiveness of your controls.
  2. Use labels such as high, medium, or low to denote the likelihood of a threat event, instead of numerical scores.

Step 6: Assess the Impact a Threat Could Have

  1. Assess the potential consequences of an incident in which an asset is lost or compromised.
  2. Consider factors such as the role of the asset, its value to the organisation, and its sensitivity.
  3. Conduct a business impact analysis or mission impact analysis report to quantify or qualify the impact on the organisation’s information assets.

Step 7: Prioritise the Risks

  1. Determine the level of risk to the IT system for each threat/vulnerability pair.
  2. Consider the likelihood of the threat occurring, the approximate cost of the occurrence, and the adequacy of existing or planned security controls.
  3. Use a risk-level matrix to estimate risk and categorise risks as high, medium, or low based on the calculation.

Step 8: Recommend Controls

  1. Based on the level of risk, recommend actions to mitigate the identified risks.
  2. For high-risk threats, develop a plan for corrective measures as soon as possible.
  3. For medium-risk threats, develop a plan for corrective measures within a reasonable time frame.
  4. For low-risk threats, decide whether to accept the risk or implement corrective actions.

Step 9: Document the Results

  1. Create a comprehensive report that outlines the assessment results and aids management in making informed decisions.
  2. Include information on each threat, associated vulnerabilities, at-risk assets, potential impact on the IT infrastructure, probability of occurrence, and recommended control measures and costs.
  3. Highlight key remediation steps that can address multiple risks.


Online security risk assessments are essential for protecting organisations from potential cyber threats. By conducting regular assessments, organisations can gain valuable insights into vulnerabilities and prioritise their security efforts effectively. These assessments provide numerous benefits, including the identification of valuable IT assets, understanding of risks, vulnerability identification and remediation, cost mitigation, regulatory compliance, improved customer trust, and informed decision-making.

By following the step-by-step process outlined in this guide, organisations can conduct comprehensive online security risk assessments and develop robust risk management strategies. Implementing these strategies will significantly enhance cybersecurity and safeguard critical assets from potential threats.
