Information Security Risk Assessment
Build a defensible view of security risk by connecting assets, threats, vulnerabilities, existing controls and business impact.
A structured risk process
- 01
Asset identification
Identify the systems, data, services and business processes relevant to the assessment.
- 02
Threat identification
Identify realistic threat events and threat actors relevant to the environment.
- 03
Vulnerability analysis
Identify weaknesses in technology, architecture, process or governance.
- 04
Control review
Evaluate the safeguards already in place and the evidence supporting them.
- 05
Likelihood assessment
Estimate how plausible or frequent a risk event may be.
- 06
Impact assessment
Evaluate financial, operational, regulatory, security and reputational impact.
- 07
Risk rating
Combine likelihood, impact and control effectiveness using the agreed methodology.
- 08
Risk treatment
Define mitigation, transfer, avoidance or acceptance options.
- 09
Residual risk
Assess the remaining risk after planned treatment.
- 10
Management reporting
Provide a risk register and prioritized treatment plan.
Assessments can be aligned with recognized information-security and risk-management frameworks, including ISO/IEC 27001, ISO/IEC 27005, the NIST Cybersecurity Framework and relevant NIST risk-management guidance, depending on the engagement objective.
Frequently asked questions
What do we receive at the end?
A risk register and a prioritized treatment plan, supported by the risk ratings and the reasoning behind them.
Which framework do you use?
The engagement objective decides. Assessments can be aligned with ISO/IEC 27001, ISO/IEC 27005, the NIST Cybersecurity Framework and relevant NIST risk-management guidance.
Do you assess residual risk?
Yes. Residual risk is assessed after planned treatment so management can see what remains once the treatment plan is delivered.
How is risk rated?
Likelihood, impact and control effectiveness are combined using the methodology agreed for the engagement, and the scale is applied consistently across findings.
How much does it cost?
Scope drives effort. Describe the environment, objective and deadline in the assessment request and we will propose the appropriate scope.
Discuss the scope of your assessment
Tell us what you need to assess, your target timeline and the environment involved. We will review the scope and identify the appropriate next step.
