If your business relies on the cloud as most do, you’re also relying on someone else’s infrastructure to store, manage, and protect your data. But here’s the reality: 80% of companies experienced a cloud-security breach in the past year. That means the odds are against you unless you take active, informed steps to secure your environment.
Even though the cloud offers flexibility, scalability, and cost savings, it also introduces unique risks.
| As Daniel Cornell, Business Development, Nortec Communication puts it: “The cloud isn’t more or less secure than on-premises, it’s differently secure.” |
This blog will help you understand what cloud security is, why it matters, how it works, and what practical steps you can take to protect your business from today’s evolving cyberthreats.

What Is Cloud Security?
Cloud security refers to the collection of technologies, processes, and policies designed to protect data, applications, and systems within cloud environments. When you ask what is cloud computing security, you’re essentially exploring the architecture and best practices that safeguard your workloads, whether hosted in public, private, or hybrid clouds.
At its core, cloud security is about achieving three foundational goals often called the CIA Triad:
- Confidentiality: Ensuring that only authorized users have access to your data and services.
- Integrity: Maintaining data accuracy and preventing unauthorized changes.
- Availability: Keeping cloud systems accessible and reliable, even during cyberattacks or failures.
In simpler terms, cloud security ensures that the flexibility and scalability of the cloud don’t come at the cost of control, privacy, or compliance.
What Is Cloud Security and How It Works
Understanding how cloud security works begins with recognizing its layered nature. No single control or tool can protect everything. You need a holistic strategy that addresses identity, access, data, networks, and ongoing monitoring.
1. Identity and Access Management (IAM)
Strong IAM policies prevent unauthorized access by limiting who can log in, what they can view, and what they can change. Implementing role-based access control (RBAC) and multi-factor authentication (MFA) is essential.
2. Encryption Everywhere
Data should be encrypted in transit (as it moves between users and servers) and at rest (when it’s stored in the cloud). Even if attackers gain access, encryption ensures they can’t read or exploit that data.
3. Network Security Controls
Firewalls, intrusion detection systems, and virtual private clouds (VPCs) help segment and isolate your workloads from unauthorized traffic.
4. Data Loss Prevention (DLP)
DLP technologies detect and block attempts to transfer sensitive data outside your environment, helping prevent leaks through misdirected emails, insider actions, or malicious uploads.
5. Monitoring and Incident Response
Ongoing visibility is critical. Continuous monitoring allows you to detect unusual behavior early, respond rapidly, and prevent escalation.
Why Cloud Security Matters More Than Ever
The cloud is now integral to digital transformation, but its convenience has also made it a prime target for cybercriminals. According to a report, 23% of all cloud security incidents result from simple misconfigurations, settings that leave storage buckets or workloads open to the public.
Moreover, 88% of cloud data breaches are caused by human error. That means your people, processes, and oversight play as big a role in protection as any tool.
For organizations bound by regulations like HIPAA, PCI DSS, or GDPR, cloud security is also a matter of legal compliance. Breaches don’t just lead to downtime or financial loss, they can trigger investigations, lawsuits, and permanent damage to your brand reputation.
Understanding What Is Infrastructure Security in Cloud Computing
To fully secure your environment, you must understand what infrastructure security is in cloud computing. This focuses on protecting the foundational systems, the virtual machines, networks, and storage, that your cloud applications rely on.
Infrastructure security includes patch management, firewall configurations, network segmentation, and endpoint protection. It also means ensuring that your providers (AWS, Microsoft Azure, Google Cloud, etc.) meet compliance standards such as ISO 27001, SOC 2, and HIPAA.
If your infrastructure layer isn’t secure, every other control you implement is built on sand.
What Is Cloud Workload Security?
While infrastructure security focuses on the foundation, cloud workload security deals with protecting the specific applications and data processes running within your cloud. A “workload” could be a database, a virtual machine, or a containerized app.
Cloud workload security solutions monitor and control how those workloads behave. They look for configuration errors, unauthorized access attempts, and vulnerabilities in the code or runtime environment.
For example, an attacker who gains access to one container shouldn’t be able to jump to another. Workload-level isolation and continuous vulnerability scanning make sure that doesn’t happen.
What Are Cloud Security Threats? Recognizing the Risks That Matter
When it comes to cloud security threats, awareness is your first defense. Here are the most common and dangerous risks you need to manage:
1. Misconfiguration
This remains the leading cause of cloud data exposure. A single unchecked setting can make entire databases public.
2. Data Breaches
Hackers target cloud accounts with weak passwords or shared credentials to access sensitive information.
3. Insider Threats
Employees or contractors can intentionally or accidentally expose data.
4. Insecure APIs
Unsecured or poorly configured APIs can be exploited to gain access or disrupt services.
5. Credential Theft and Account Hijacking
Phishing and social engineering remain top causes of unauthorized access.
6. Denial of Service (DoS) Attacks
Attackers flood cloud resources with traffic to knock them offline.
Understanding these threats lets you prioritize investments and policies where they’ll have the most impact.
What Is Data Security in Cloud Computing?
The global cloud computing market is projected to reach USD 2,297.37 billion by 2032, growing at a steady 17% CAGR from 2023 to 2032. As more businesses move their operations to the cloud, understanding what data security in cloud computing truly means becomes essential—it’s about ensuring that every piece of data stored, transferred, and managed across cloud platforms remains protected, compliant, and resilient against evolving threats.
It involves the combined use of encryption, access controls, tokenization, and backup strategies to safeguard data throughout its lifecycle. Key best practices include:
- Encrypting sensitive data before uploading it to the cloud.
- Applying consistent data classification to determine sensitivity levels.
- Using cloud provider tools for data redundancy and integrity verification.
- Regularly backing up data to geographically diverse locations.
By securing your data at every stage from upload to deletion, you maintain control even when using third-party infrastructure.
The Shared Responsibility Model in Cloud Security
A key aspect often overlooked is who’s responsible for what in the cloud. The shared responsibility model clarifies that cloud providers like AWS or Microsoft Azure are responsible for securing the cloud infrastructure, while you are responsible for security in the cloud, including your data, configurations, and user access.
| Cloud Model | Provider Responsibility | Your Responsibility |
|---|---|---|
| IaaS (Infrastructure-as-a-Service) | Securing data centers, hardware, and network | OS updates, data, apps, and access policies |
| PaaS (Platform-as-a-Service) | Infrastructure and OS | Application code, data, configuration |
| SaaS (Software-as-a-Service) | Full application and infrastructure | User data, permissions, and compliance |
Failing to understand this distinction leads to security blind spots, the most common cause of cloud incidents.
Best Practices to Strengthen Cloud Security
Now that you understand the threats, here’s how you can act on them effectively:
- Enable MFA everywhere including admin and third-party integrations.
- Audit your configurations regularly and automate this through CSPM (Cloud Security Posture Management) tools.
- Use encryption keys you control rather than relying solely on provider-managed ones.
- Segment workloads isolate sensitive systems from general workloads.
- Train your team’s human error remains the biggest risk vector.
- Automated responses tools like SIEM and SOAR help detect and react faster.
Following these steps ensures that security becomes a built-in feature of your operations, not an afterthought.
