The majority of required processes are already built into certified public clouds, automatically satisfying most security audit requirements. Existing certifications of public clouds can significantly facilitate the compliance audit process, ensuring organizations maintain an effective and high-quality level of security in accordance with established standards.


Risks of Transitioning to Cloud Services:


Data Security:

  • Cloud providers store data on remote servers, raising concerns about organizations having limited control over their data. Organizations seek assurance that their data is protected from unauthorized access.


Identity and Access Management (IAM):

  • Organizations need a clear overview of how users access resources and how the management of roles, rights, and privileges is handled. Confidence is crucial in ensuring that only authorized users have access to designated resources, and administrator accounts are secure and controlled. According to a Delinea study, 74% of data breaches are related to privilege abuse. To address these challenges, some organizations prefer transitioning from individual IAM solutions to commercial solutions like Privileged Access Management (PAM).


Data Transfer and Bandwidth Limitations:

  • Migrating a large volume of data to the cloud can be time-consuming and constrained by network bandwidth. Uploading or downloading substantial data volumes over the Internet can become a bottleneck, especially in conditions of limited network infrastructure.


Compliance:

  • Organizations must adhere to various regulations and standards such as GDPR, HIPAA, PCI-DSS, and others. Cloud providers may offer compliance tools, but organizations need to ensure full compliance on their part.


Key Management:

  • Inadequate configuration management and improper certificate management can lead to severe consequences. Thorough examination and implementation of best practices, such as centralized management, automated certificate management, secure key management, and compliance management, can help overcome these challenges and ensure the security of digital communications in the cloud.
