What is Cloud Computing Security?
Cloud computing security is the combination of technologies, policies, and controls that protect cloud infrastructure, applications, and data against unauthorised access, breaches, and service disruptions.
It covers three layers:
Identity and Access Management (IAM): Controls who can access what and under what conditions.
Data encryption: Renders data unreadable if intercepted, both in transit between systems and at rest in storage.
Network protection: Monitors and controls traffic entering and leaving your cloud environment to block malicious activity.

Top Cloud Computing Security Issues
Read the following key cloud computing security issues faced by businesses every day:
Cloud Misconfiguration
Misconfiguration is the leading cloud vulnerability, and it’s almost entirely preventable. Cloud misconfigurations account for roughly 15% of breach incidents, and in one 2025 case, a global automotive firm accidentally exposed 10TB of customer data via a misconfigured AWS S3 bucket and hard-coded credentials.
Common misconfiguration mistakes:
- Leaving storage buckets (S3, Azure Blob, Google Cloud Storage) publicly accessible
- Granting overly permissive IAM roles
- Disabling encryption on databases
- Leaving default credentials unchanged
- Failing to restrict outbound network access
The fix: Implement Cloud Security Posture Management (CSPM) tools that continuously scan your cloud environment for misconfigurations and surface them before attackers do.
Weak Identity and Access Management (IAM)
Weak IAM remains one of the top cloud security challenges in 2025, with overprivileged accounts, poor password hygiene, and a lack of multi-factor authentication significantly increasing the risk of cloud data breaches. Weak IAM contributes to 80% of cloud breaches involving stolen or compromised credentials.
The fix: Enforce least-privilege access (users get only the permissions their role requires). Implement MFA universally. Review access rights quarterly and revoke access immediately on employee termination.
Data Breaches
The average cost of a data breach climbed to $4.88 million in 2024, encompassing immediate financial losses, long-term reputational damage, and regulatory penalties.
82% of data breaches involve data stored in the cloud, and 42% of small businesses store sensitive customer data on cloud platforms without encryption.
The fix: Encrypt all data at rest and in transit. Implement anomaly detection to flag unusual access patterns in real time. Never store secrets (API keys, credentials) in source code repositories.
Insecure APIs
APIs are the connective tissue of cloud computing, linking your applications, services, and data. They’re also one of the most exploited attack surfaces. A single compromised API can have cascading effects across multiple systems, and in 2025, this problem continues to grow as cloud environments become more complex.
Common API vulnerabilities:
- Missing or weak authentication
- Excessive data exposure (returning more data than the caller needs)
- No rate limiting (enabling brute-force attacks)
- Broken object-level authorization
The fix: Require strong authentication on every API endpoint (OAuth 2.0, JWT). Implement API gateways that enforce rate limiting, logging, and access controls. Conduct regular API security testing as part of your development cycle.

Insider Threats
Malicious insider attacks in 2025 had the highest average breach cost, nearly $5 million. 83% of organisations reported insider attacks in the past year, and organisations experiencing 11 to 20 insider attacks saw a fivefold increase over a 12-month period.
The fix: Implement role-based access control (RBAC). Log all privileged user activity. Use User and Entity Behaviour Analytics (UEBA) to flag activity that deviates from normal patterns, such as large data exports, off-hours logins, and accessing systems outside a user’s normal scope.
Ransomware Targeting Cloud Environments
In 2025, ransomware groups used AI and automation to launch attacks with unprecedented speed, including ransomware-as-a-service (RaaS) and multi-extortion ransomware, which increase both the frequency and impact of attacks.
The fix: Maintain immutable backups stored in isolated environments that ransomware cannot reach or encrypt. Implement Endpoint Detection and Response (EDR). Run tabletop exercises that simulate a ransomware scenario so your team knows exactly what to do.
Shadow IT
Shadow IT refers to cloud applications and services your employees use without IT knowledge or approval, such as personal file storage, unauthorised SaaS tools, and consumer-grade collaboration apps.
One-third of data breaches in 2024 involved shadow IT, and 21% of companies admitted to suffering a cybersecurity event due to an unsanctioned IT resource.
The fix: Deploy a Cloud Access Security Broker (CASB) to discover and inventory all cloud services in use. Establish clear, enforceable policies for SaaS adoption.

Supply Chain Vulnerabilities
Your cloud security is only as strong as your weakest vendor. Attackers increasingly compromise cloud environments by targeting third-party suppliers, managed service providers, or software dependencies rather than attacking your organisation directly.
The fix: Conduct security assessments of all third-party vendors before onboarding. Include security requirements in vendor contracts such as minimum controls, breach notification windows, and the right to audit. Monitor for anomalous activity from third-party integrations.
Compliance Violations
Cloud environments complicate compliance. Multi-cloud deployments, cross-border data flows, and the shared responsibility model all create gaps that lead to violations of GDPR, HIPAA, PCI-DSS, and India’s DPDP Act.
The fix: Map your compliance obligations to specific cloud controls. Use cloud compliance solutions that continuously monitor your posture against regulatory frameworks and generate audit-ready reports automatically.
AI-Powered Threats and AI Security Risks
AI is transforming cloud security in two directions simultaneously. 84% of organisations now use AI in the cloud, introducing new risks, including AI-related CVEs that enable remote code execution.
The fix: Counter AI-powered threats with AI-powered defences. The threat detection tools that use machine learning to identify anomalous behaviour rather than relying on known signatures.

Key Cloud Security Challenges Businesses Face
Beyond individual threats, SMBs face structural challenges that make cloud security harder to maintain:
- Cloud environments lack visibility through which organisations can monitor their operations
- Organisations struggle to manage multiple cloud providers because of operational difficulties
- Organisations struggle to handle shared responsibility models because they create confusion
- The cybersecurity industry faces a problem because there are not enough skilled professionals for cybersecurity work
How to Prevent Security Issues in Cloud Computing
The following are the measures that can be used to prevent issues in cloud computing:
Strong Identity and Access Management (IAM)
The most effective method for reducing cloud security threats is to implement access controls that restrict system access to authorised personnel only. Strong Identity Access Management systems protect sensitive data and applications by permitting access only to verified authorised personnel.
Data encryption
Data encryption is an essential element for securing data in cloud computing environments. The system protects intercepted data from unauthorised access by rendering it unreadable.
Regular Security Audits
The process of auditing helps organisations discover hidden security weaknesses within their cloud systems. System configurations that are properly established will develop security weaknesses over time due to system updates, new integrations, and human error.
Automated Monitoring Tools
Current manual monitoring methods fail to meet the demands of monitoring systems in complex cloud environments. Modern enterprises require sophisticated security solutions for their cloud environments to detect threats and monitor system status throughout the day.
Secure Cloud Architecture Design
The design process needs to incorporate security measures which should not be delayed until after the system goes live. A cloud architecture design which follows proper structural guidelines will reduce security risks and stop most cloud computing security threats from happening.
From Setup to Security, We Handle It All
Mitigata offers end-to-end implementation so your CASB deployment is smooth.
Train Your People
Over 94% of breaches involve human interaction. Your security stack is only as strong as the people who operate it and work around it.
Effective security training:
- Quarterly security awareness sessions (not just annual)
- Simulated phishing campaigns to test and reinforce learning
- Clear, accessible policies for cloud service usage and data handling
Build and Test Your Incident Response Plan
When a breach occurs, the speed of your response determines the cost. Traditional incident response plans fail to account for cloud complexity, leading to delayed detection and mitigation.
Your cloud incident response plan should cover:
- How to contain a compromised cloud account immediately
- Who is responsible for each step of the response
- How to preserve evidence for forensic investigation
- Regulatory notification timelines under GDPR/DPDP
- Post-incident review and control improvement process
The best cloud security tools do more than monitor threats, discover the features that actually matter.

Key Types of Cloud Security Tools
The different types of Cloud security tools are as follows:
CSPM tools
As cloud computing security becomes more complex, businesses can no longer rely on a single layer of protection. The organisation requires a combination of advanced cloud security tools and integrated cloud security solutions to handle its security needs throughout various cloud environments.
IAM tools
IAM tools establish access control systems that determine user rights to cloud system resources. The security system requires these tools because they establish access rights through authentication and protect cloud resources from unauthorised access.
Threat Detection and SIEM
Threat detection tools(SIEM) monitor cloud environments in real time for suspicious activity, such as unauthorised access attempts, unusual data movement, and anomalous API calls, and alert your team before damage is done.
Choosing the right SIEM solution starts with knowing which companies are leading the market in India.
Cloud Access Security Broker (CASB)
CASB tools sit between your users and cloud services, enforcing security policies and providing visibility into shadow IT – the unauthorised SaaS tools employees use without IT knowledge.
Cloud-Native Application Protection Platform (CNAPP)
CNAPP platforms combine CSPM, workload protection, and container security into a unified platform. A single CNAPP dashboard provides real-time telemetry and security posture across your environment, and automated remediation playbooks can prevent vulnerabilities from escalating into breaches.
| Tool Type | Primary Function | Key Benefit | Best For |
