p class=”sqsrte-small”>Cloud security means multiple teams with a shared responsibility.
The transition to cloud computing is an evolution that many organisations are still undertaking to improve efficiency, scalability, and flexibility in their operations.
Cloud services offer recognised advantages, such as moving IT infrastructure costs to operating expenditure rather than capital expenditure, enhanced governance, and better collaboration, however they also introduce specific security considerations that need to be addressed to protect systems and data from compromise, and to maintain legal and regulatory compliance.
However, some organisations are now moving back to on-premise systems due to concerns around high operational costs, cloud performance issues, or cyber security.
Clearly, the cloud is not the panacea some thought it would be. But can be be secure, and if so – how?
Data Protection and Encryption
One of the primary concerns when moving to the cloud is the protection of data, both at rest and in transit. Data encryption is a fundamental security measure that should be implemented to safeguard information from unauthorized access. Organisations should ensure that their cloud service provider offers robust encryption methods for data at rest and in transit. Additionally, the use of encryption keys must be carefully managed, with keys securely stored and access strictly controlled.
Access Management and Identity Authentication
Effective access management is crucial in a cloud environment to prevent unauthorised access to data and resources. Organisations should leverage identity and access management (IAM) solutions that provide multi-factor authentication (MFA), role-based access control (RBAC), and the principle of least privilege, to minimize the risk of compromise. It is also essential to regularly review and update access permissions to reflect changes in roles and responsibilities within the organisation.
