Cloud security works by implementing a combination of advanced technologies,
processes, and policies designed to protect data, applications, and
infrastructure in cloud computing environments. This is a breakdown of how cloud
security usually works:
Data encryption: Encryption is essential to cloud security because it protects data in transit
and at rest. Cloud data is encrypted by applying encryption techniques to
transform plaintext data into ciphertext.
Network Security: Virtual Private Cloud (VPC) environments and firewalls are used to implement
network security. While VPCs offer isolated network environments within the
cloud, improving security and control over network access, firewalls monitor and
manage incoming and outgoing network traffic to and from the cloud environment.
Identity and Access Management (IAM): Another essential cloud security component is Identity and Access Management
(IAM) which uses authentication techniques to confirm the legitimacy of users or
devices before allowing access to cloud resources.
Incident Detection and Response: In the event of a security issue, actions are guided by a predetermined incident
response plan, which minimizes the impact and expedites the return of normal
operations.
Compliance Management: Adherence to compliances ensure that cloud operations and services abide by
rules and guidelines unique to the industry, including GDPR, HIPAA, PCI-DSS, and
others.
