In today’s digital landscape, businesses are increasingly turning to cloud computing to store and manage their data. While the cloud offers many benefits, such as cost savings and scalability, it also presents unique risks that businesses must be aware of and mitigate.
A cloud risk assessment is a crucial step in understanding and managing these risks. In this article, we’ll discuss the five key steps to conducting a cloud risk assessment and provide a checklist for businesses to follow.
Why Conduct a Cloud Risk Assessment?
A cloud risk assessment is a process of identifying, analysing, and evaluating potential risks associated with using cloud services. It helps businesses understand the potential threats to their data and systems and develop strategies to mitigate those risks.
Conducting a cloud risk assessment is essential for several reasons:
- Identify potential risks: A risk assessment helps businesses identify potential risks that could impact their data and systems. This includes risks such as data breaches, service disruptions, and compliance violations.
- Prioritize risk mitigation efforts: By understanding the level of risk associated with different cloud services, businesses can prioritize their risk mitigation efforts and allocate resources accordingly.
- Ensure compliance: A risk assessment can help businesses ensure they are meeting regulatory requirements and industry standards for data security and privacy.
- Protect business reputation: A data breach or compliance violation can damage a business’s reputation and erode customer trust. A risk assessment can help prevent these incidents and protect the business’s reputation.
- Save costs: By identifying and mitigating potential risks, businesses can avoid costly data breaches, service disruptions, and compliance fines.
Step 1: Identify Cloud Services in Use
The first step in conducting a cloud risk assessment is to identify all the cloud services in use within the organization. This includes both sanctioned and unsanctioned services.
Sanctioned services are those that have been approved by the organization’s IT department, while unsanctioned services are those that employees may be using without IT’s knowledge.
To identify all the cloud services in use, businesses can use a cloud access security broker (CASB) or a cloud discovery tool. These tools can scan the organization’s network and identify all the cloud services in use.
As part of Dionach’s cloud security assessment methodology we work together with the client to define the scope and objectives of the assessment. This involves identifying and prioritizing the systems to be tested, as well as the assessment methods and tools to be used.
Step 2: Assess the Risks
Once all the cloud services have been identified, the next step is to assess the risks associated with each service. This involves evaluating the security controls and compliance measures in place for each service.
Some key areas to consider when assessing risks include:
- Data security: How is data stored, encrypted, and protected from unauthorized access?
- Service availability: What measures are in place to ensure the service is available when needed?
- Compliance: Does the service comply with relevant regulations and industry standards?
- Vendor security: How does the service provider ensure the security of their systems and data centres?
- Data ownership and control: Who owns the data stored in the service, and how can it be accessed and deleted?
- Data backup and recovery: What measures are in place to backup and recover data in case of a disaster or service disruption?
As part of Dionach’s cloud security assessment methodology will conduct security assessments and configuration reviews against all cloud providers, cloud computing models and cloud services. The assessment is conducted using a combination of automated tools and manual inspection of the cloud environment against vendor and industry best practises. Reviews can also be carried out against security benchmarks such as those provided by the Centre for Internet Security (CIS).
Step 3: Prioritize Risks
After assessing the risks associated with each cloud service, the next step is to prioritize them. This involves determining the likelihood and impact of each risk and ranking them in order of importance.
Some risks may be more critical than others, and businesses should focus their risk mitigation efforts on those with the highest likelihood and impact.
Dionach’s cloud security assessment includes a detailed report with each misconfiguration and vulnerability documented, with the impact and likelihood individually risk assessed.
Step 4: Develop a Risk Mitigation Plan
Once the risks have been prioritized, the next step is to develop a risk mitigation plan. This plan should outline the steps the organization will take to reduce or eliminate the identified risks.
Some common risk mitigation strategies include:
- Data encryption: Encrypting data stored in the cloud can help protect it from unauthorized access.
- Multi-factor authentication: Requiring users to provide multiple forms of identification, such as a password and a code sent to their phone, can help prevent unauthorized access to cloud services.
- Regular backups: Regularly backing up data stored in the cloud can help ensure it can be recovered in case of a disaster or service disruption.
- Compliance audits: Conducting regular compliance audits can help ensure cloud services are meeting regulatory requirements and industry standards.
- Vendor due diligence: Before using a cloud service, businesses should conduct due diligence on the service provider to ensure they have appropriate security measures in place.
Dionach’s cloud security assessment report includes individual recommendations for each issue identified, but also strategic recommendations to assist you in making informed decisions and achieve long-term goals and objectives.
Step 5: Monitor and Update the Risk Assessment
A cloud risk assessment is not a one-time event. Risks and cloud services are constantly evolving, and businesses must regularly monitor and update their risk assessment to stay ahead of potential threats.
This involves regularly reviewing the risk assessment and updating it as needed, as well as staying informed about new cloud services and potential risks.
Cloud Risk Assessment Checklist
To help businesses conduct a thorough and effective cloud risk assessment, here is a checklist of key steps to follow:
- Use a CASB or cloud discovery tool to identify all cloud services in use.
- Include both sanctioned and unsanctioned services in the assessment.
- Evaluate the security controls and compliance measures in place for each service.
- Consider data security, service availability, compliance, vendor security, data ownership and control, and data backup and recovery.
- Determine the likelihood and impact of each risk.
- Rank risks in order of importance.
- Identify strategies to reduce or eliminate the identified risks.
- Consider data encryption, multi-factor authentication, regular backups, compliance audits, and vendor due diligence.
- Regularly review and update the risk assessment.
- Stay informed about new cloud services and potential risks.
Conclusion
Conducting a cloud risk assessment is a crucial step in understanding and managing the risks associated with using cloud services.
By following the guidelines outlined in this article and using the provided checklist, companies can identify potential risks, prioritize their efforts to mitigate those risks, and protect their data and systems from harm.
