Identifying, evaluating and analyzing risk

What is a risk assessment?

In the fast-paced and interconnected digital world, the security of information and data has become a paramount concern for businesses, governments, and individuals alike. Cyber threats are continuously evolving, and attackers are becoming more sophisticated in their methods, targeting vulnerabilities in networks, systems, and applications. To safeguard against potential breaches and data compromises, organizations must adopt proactive approaches to cybersecurity. One essential practice that plays a pivotal role in this context is Risk Assessment.

Risk Assessment is a foundational component of the Risk Management Lifecycle. Risk assessment is the process of identifying, evaluating and analyzing risk. Risk identification involves identifying the threats, vulnerabilities, assets, and existing controls. Risk evaluation focuses on determining the likelihood and impact if the vulnerabilities are exploited by the threats, resulting in damage to the asset. Risk analysis puts everything together, informs the organization about the risk involved, and helps determine how effective existing controls are and the gaps between current and desired risk states.

Benefits of risk assessment

  1. Identify Security Vulnerabilities: The primary objective of a risk assessment is to identify security vulnerabilities within an organization's information technology assets.

  1. Enhance Cyber Security Posture: Once the security vulnerabilities have been identified, the organization can take action to remediate these; thereby decreasing the overall risk to the organization's operations, information technology assets, and data.

  1. Improve Risk Management Practice: Regular risk assessment continually improves the risk management practices within the organization, continually reduce residual risk, and identifies new risks that have been introduced since the last risk assessment was conducted.

  1. Stay Compliant: Many industries and regulatory frameworks require periodic risk assessments to ensure compliance with security standards. These assessments help organizations meet the requirements and maintain their reputation in the market.


The approach for IT security risk assessment involves a series of steps that aim to identify, analyze, and mitigate potential risks to an acceptable level. The following steps are generally followed:

  1. Identify and prioritize assets: Identify the assets that need protection and prioritize them based on their criticality.

  1. Identify threats: Identify the potential threats that could exploit vulnerabilities in the assets.

  1. Identify vulnerabilities: Identify the weaknesses in the assets that could be exploited by the threats.

  1. Analyze existing controls: Analyze the existing controls in place to protect the assets and identify any gaps.

  1. Determine the likelihood of an incident: Determine the likelihood of a threat exploiting a vulnerability and causing an incident.

  1. Assess the impact a threat could have: Assess the impact of an incident on the organization.

  1. Prioritize the risks: Prioritize the risks based on their likelihood and impact.

Types of assessment services

Organizations can perform a number of different types of risk assessments to identify risks, threat,s or vulnerabilities. Business requirements and objectives determine the type of risk assessment.

Some of the risk assessments include:

  • Risk Assessment: Identify and classify risks associated with IT systems and processes.
  • Gap Assessment: Identify compliance with policies, standards, or regulatory requirements.
  • Threat Modeling: This threat-centric assessment is used to identify specific threat scenarios that may occur.
  • Maturity Assessment: Determine the maturity of processes or capabilities within an organization. Assessment is typically conducted against an industry-recognized standard such as NIST.
  • Architecture, Design and Configuration Review: Determines the security posture of the organization's architecture, design, and configuration of IT/Security assets.
  • Code Scan / Code Review: A combination of automated code scanning of software code to identify vulnerabilities and a manual review of logic errors and security vulnerabilities.
  • Audit: A rigorous and formal inspection of controls or processes to determine whether they are being followed and meeting their objectives.

In an age where cyber threats are constantly evolving, the importance of Risk Assessments cannot be overstated. Risk Assessments allow an organization to review its processes, practices and systems and discover risks that may be exploited by malicious actors, and compromise the organization's assets and data. This practice provides a comprehensive understanding of an organization's risk posture, enabling them to prioritize their resources and efforts effectively to reduce the risk of compromise by external threats. By embracing proactive cybersecurity measures like this service, organizations can safeguard their digital frontier, protect sensitive data, and maintain the trust of their stakeholders in an increasingly interconnected world.
