- Impact analysis evaluates the potential consequences of security risks on business operations, financial stability, compliance, and reputation. It helps organizations understand what’s at stake and ensure that high-risk areas receive priority attention. A severe impact could include data breaches, financial losses, regulatory fines, or operational downtime.
- Risk treatment plan
- A risk treatment plan outlines strategies to address identified risks. This includes risk mitigation (implementing controls), risk avoidance (eliminating certain activities), risk transfer (using cyber insurance), or risk acceptance (acknowledging a risk without action). A structured plan ensures a proactive approach to managing IT security risks.
Types of security risk assessments
Physical security assessment
Physical security assessments aim to protect against higher risks to building security and occupant safety. The purpose of physical security controls is to protect personnel and hardware from tangible threats, such as unauthorized access and environmental factors. Facility security officers can assess vulnerabilities using a facility security assessment checklist, ensuring that all potential risks are identified and mitigated.
Unauthorized access to sensitive data stored on an internal database server poses a physical security risk. This type of risk can lead to significant vulnerabilities within an organization. Security controls can be categorized into physical, administrative, and technical types based on their functions, and further divided by function into categories such as detect, prevent/deter, correct, and compensate.
IT security assessment
IT security assessments play a vital role in evaluating the overall condition of IT infrastructure. They also help to review the effectiveness of communications pathways. These assessments identify broad system vulnerabilities and misconfiguration issues that could leave companies exposed. In a security assessment, the Red Team represents attack vectors and conducts penetration testing to identify vulnerabilities and test the effectiveness of existing security controls.
Operational security control defines the effectiveness of access authorities, authentication, and security topologies in protecting IT resources. Regular IT security assessments ensure that IT systems remain secure and resilient against potential cyber threats.
Data security assessment
Data security assessments focus on ensuring robust controls are in place for safeguarding sensitive information from unauthorized access. Key access controls evaluated in a Data Security Assessment include least privilege and zero trust access controls, which limit access to sensitive data based on user roles and responsibilities.
Strong identity management processes ensure that only authorized users access control systems sensitive information.
Network segmentation is examined to limit data access and enhance overall data security, making it harder for unauthorized users to access sensitive information.

Knowing what needs protection allows security teams to implement appropriate controls and policies.
Identify threats and vulnerabilities
Identifying threats and vulnerabilities is crucial for understanding the potential risks to an organization’s assets. A vulnerability is a flaw (outdated software, weak passwords, misconfigurations, etc) that exposes a company to potential threats, while a threat is an event (cyberattacks- malware, and phishing attacks) that can cause damage to assets or processes. The analysis of vulnerabilities should cover technical, physical, and process flaws to provide a comprehensive view of potential risks.
Identifying threats and vulnerabilities enables organizations to take proactive measures to mitigate risks and enhance their security.
Risk analysis and prioritization
Risk analysis and prioritization help organizations visualize their risk landscape, highlight security gaps, and prioritize issues. Identifying the likelihood of vulnerabilities being exploited helps organizations address the highest-risk issues first. After identifying risks during a security assessment, prioritize risks by assigning a risk rating, which involves assessing the likelihood and impact of an exploit.
A risk matrix framework (NIST RMF, OCTAVE,ISO 31000, FAIR, ITIL and COBIT) is used to classify each risk scenario, aiding in the prioritization process. Remediation responses should be prioritized based on risk ratings and impacts against the overall remediation budget. Effective prioritization of remediation efforts helps organizations address critical vulnerabilities and minimize potential threats.
Implementing security controls
Once risks are identified, organizations must evaluate existing security controls and introduce new measures to mitigate threats. These controls can be preventive (firewalls, MFA, encryption), detective (intrusion detection systems), or corrective (incident response plans, backup recovery). Implementing multi-factor authentication, network segmentation, and security awareness training are common strategies to enhance defenses. Effective mitigation reduces vulnerabilities and strengthens the overall security posture.
Documentation and reporting
An effective risk assessment report should include details such as risk scenarios, existing controls, and mitigation plans. A variety of valuable information regarding threats and risks is collected during this process.
Specific remediation plans are developed after determining appropriate controls for vulnerabilities, including detailed steps for remediation and associated costs. Corrective actions should be assigned with due dates and priority levels to ensure timely responses, and assignments with time frames and monitoring steps should be included in the remediation plan.
