Cloud computing covers a wide range of topics. One must have an indepth knowledge of these wide range of topics before writing cloud certification exam. These topics are$$

Governance and Enterprise Risk Management

THE Largest Risk

The largest risk is Compliance and information governance or IAM with a risk score of $20.$ This is due to the high likelihood of IAM issues occurring and the significant impact they can have on overall cloud security.

Smallest Risk

The smallest risk is application$/$network security with a risk score of $12.$ This is because while important, the likelihood of issues arising from not following best practices is lower compared to other areas, and the impact is also relatively lower as this is considerably managed by a third party.

Impact on Choice of Cloud Solution or Vendor

Identity and Access Management $($IAM$)$: Given its high risk, a cloud solution or vendor with robust IAM capabilities, such as multi$-$factor authentication $($MFA$),$ role$-$based access control $($RBAC$),$ and detailed audit logs$,$ would be preferred.

Network $/$Application Security: Solutions with advanced network security features like virtual private clouds $($VPCs$),$ firewalls, and intrusion detection$/$prevention systems $($IDS$/$IPS$)$ would be favored. Vendors provide the necessary tools required for application deployment and development $.$

$$

Compliance and Legal Issues: Vendors with certifications and compliance with industry standards $($e$.$g$.,$ GDPR$,$ HIPAA$)$ would be essential to ensure legal and regulatory adherence.

Incidence response and business continuity$//$Disaster recovery

: Providers with well$-$defined incident response plans and $24/7$ support would be critical to quickly address and mitigate security incidents.
