What is Cloud Security?

To answer the question of what is cloud security, it refers to a set of policies, controls, procedures, and technologies designed to protect data, applications, and infrastructure associated with cloud computing. It encompasses a broad range of security measures to safeguard cloud-based systems from cyber threats, data breaches, and unauthorised access. Cloud security ensures the confidentiality, integrity, and availability of data stored and processed in the cloud along with the help of cyber security insurance.

Types of Cloud Security

1. Data Security:

It involves protecting data from unauthorised access and breaches. This includes encryption, data masking, and access control mechanisms.

2. Network Security:

It focuses on securing the network infrastructure of cloud environments, including firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs).

3. Application Security:

It ensures that applications hosted in the cloud are secure from vulnerabilities and attacks through secure coding practices and regular security assessments.

4. Identity and Access Management (IAM) :

It manages user identities and controls access to cloud resources, ensuring only authorised users have access to sensitive data.

5. Compliance and Governance:

It ensures that cloud operations comply with regulatory standards and industry best practices, including data privacy laws and security frameworks.

Common Threats to Cloud Security

1. Data Breaches:

Unauthorised access to sensitive data stored in the cloud, leading to potential data theft and exposure.

2. Misconfigured Cloud Settings:

Incorrectly configured cloud settings can leave systems vulnerable to attacks and unauthorised access.
