Cloud security best practices have become more critical than ever as businesses increasingly rely on cloud environments to store sensitive data and run essential operations. With threats constantly evolving, from misconfigurations to complex cyberattacks, organizations must stay proactive in how they protect their cloud infrastructure.
In this article, we’ll explore the most important cloud security best practices that every company, regardless of size or industry, should implement.
From securing access controls to monitoring activity in real time, our goal is to help you build a resilient cloud strategy that supports growth while minimizing risk against the latest digital threats.
Common Challenges in Cloud Security
Nowadays, more and more businesses move their data and operations to the cloud, therefore, the need for strong cloud security has never been more urgent. But along with its benefits, such as scalability, flexibility, and cost savings, the cloud also introduces a unique set of challenges.
Understanding these challenges is the first step towards mitigating the risks associated with cyberattacks in cloud environments. Below, we will explore some of the most common cloud security challenges individuals face today.
- Misconfigured Cloud Settings
Cloud misconfigurations are among the top causes of data breaches. When default security settings are left unchanged or cloud permissions are too broad, attackers can exploit them to access sensitive data.
- Insider Threats and Human Error
Whether intentional or not, internal actors pose a significant risk. Employees may unintentionally share data, reuse weak passwords, or access systems from unsecured devices. These actions can then open the door to unauthorized users or malware.
- Inadequate Identity and Access Management (IAM)
Without proper controls over who can access what, individuals risk giving the wrong people access to critical systems or data. Poor IAM practices can quickly lead to privilege abuse or account hijacking.
- Lack of Visibility and Monitoring
In cloud environments, security teams often struggle with real-time visibility into activity across multiple platforms or services. This limits their ability to detect and respond to threats quickly.
- Compliance and Regulatory Gaps
Staying compliant in the cloud can be quite challenging. Different regions and industries have different data residency and protection laws, and businesses must always make sure that cloud configurations align with all applicable regulations.
Best Practices Checklist for Cloud Security
Given that businesses increasingly operate in digital environments, it’s essential to make cybersecurity a daily priority, not just a one-time task. Preventing a cyberattack is always more effective than dealing with the aftermath of a data breach, which can lead to long-term damage and lasting consequences.
The best practices below provide a solid foundation to help you protect sensitive information, stay compliant with regulations, and minimize your organization’s overall risk.
1. Follow the Shared Responsibility Model
Understanding the shared responsibility model is critical for effective cloud security. In this model, cloud providers are responsible for securing the infrastructure, while customers are responsible for securing their data, applications, and user access.
Each provider may define these boundaries differently, so it’s important to review the documentation specific to your cloud service. By clearly understanding your responsibilities, you can implement the necessary protection methods and avoid gaps that cybercriminals may exploit.
2. Adopt IAM with Least Privilege
Identity and Access Management (IAM) is one of the most important tools in your cloud security toolbox. Always follow the principle of least privilege by giving users and applications only the access they need to perform their duties, and nothing more.
Remember to regularly audit permissions and adjust them as roles evolve and implement multi-factor authentication (MFA) for all users whenever possible. By minimizing access, you can significantly reduce the chances of both accidental and malicious misuse.
3. Encrypt the Data in Transit and at Rest
Data is one of your most valuable assets, and encryption helps keep it safe from unauthorized access. Sensitive information should be encrypted both in transit (as it moves across the internet or within the cloud) and at rest (when stored in databases, storage buckets, or backups).
Make use of your provider’s native encryption tools and consider using a centralized key management service to enhance control. Lastly, don’t forget to rotate your encryption keys periodically.
4. Centralize Logs and Monitor Activity
Visibility is essential for detecting threats early and responding effectively.
Make sure you collect logs from all your cloud services and store them in a centralized location. Then, use Security Information and Event Management (SIEM) tools to analyze these logs and identify anomalies.
Real-time monitoring allows your team to spot unusual behavior, such as unauthorized access attempts or unexpected resource usage, and act before the issue escalates.
5. Check for Misconfiguration and Automate Posture Management
Misconfigurations are one of the main causes of cloud security incidents. Certain setup flaws can leave your environment vulnerable, such as:
- open storage buckets.
- incorrect access settings.
- exposed APIs.
To prevent this, you must regularly scan your cloud setup for configuration errors and security policy violations. Better yet, automate this process with Cloud Security Posture Management (CSPM) tools. These tools help maintain consistent configurations and compliance, allowing your team to focus on strategic initiatives.
6. Conduct Cloud Penetration Testing and Vulnerability Assessments
Routine cybersecurity testing is essential to identifying weaknesses in your cloud infrastructure.
For instance, penetration testing simulates real-world attacks to assess how your defenses respond, while vulnerability assessments help you identify known security flaws. When combined, these tests can provide a comprehensive view of your cloud environment’s risk level.
Make sure you work with qualified testers and scan your cloud systems at least once a year or after every major update to stay ahead of the latest digital threats.

7. Employ Zero-Trust Principles and Network Segmentation
Zero-trust means never assuming trust, even inside your network. Every access request should be verified, and devices and users must prove their identity and context.
Pairing this approach with network segmentation can guarantee that even if one area is compromised, the rest of your environment remains secure. You can segment workloads by sensitivity level and apply strict policies to control lateral movement.
8. Integrate Security Early in DevOps and CI/CD Pipelines
Security shouldn’t be an afterthought in your development process; it should be embedded from the beginning. This practice is known as “shift-left” security.
Make sure you integrate relevant security testing tools directly into your CI/CD pipelines to catch vulnerabilities before applications go live. Some methods that reduce risk and help resolve issues early on include:
- Code scanning
- Automated testing
- Secure coding practices
9. Build Effective Incident Response and Risk-Assessment Strategies
Not even the best defenses can prevent every single threat. That’s why having a well-defined incident response plan is crucial. Here are some common steps you can take to build an effective strategy:
- Identify key roles
- Establish communication channels
- Create clear steps for containment, investigation, and recovery
You can ultimately combine this with regular risk assessments to understand where your biggest vulnerabilities lie and how to prioritize mitigation efforts.
10. Implement Cloud Governance and Compliance
Cloud governance involves creating and enforcing policies that define how your cloud resources are managed. This includes access controls, budget tracking, and regulatory compliance.
It’s also important to make sure that your cloud environment aligns with industry standards such as ISO 27001, NIST, or GDPR. You can use cloud-native governance tools to maintain visibility and enforce rules across all relevant accounts.
11. Launch Regular Cloud-Security Training
Even today, human error remains one of the top causes of data breaches. Because of that, it’s important to provide ongoing education to your staff to keep them aware of emerging threats, as well as how to respond.
To streamline the training process, you can tailor it to specific roles, because developers, administrators, and end-users all face different risks. You should also include simulated phishing campaigns and incident response drills to build a strong security culture.
12. Streamline Security Toolsets and Use Automation
Too many tools can create confusion and reduce visibility; therefore, you should consolidate your security stack where possible and make sure your solutions integrate well.
Automation is key to scaling your cloud security strategy. Whenever possible, use automated remediation, alerting, and compliance checks to reduce manual work and respond faster to incidents.
13. Perform Regular Data Backups and Test Recovery Plans
Data loss can happen often due to breaches, system failures, or human error, so it’s important to perform regular backups of important information to make sure nothing is lost.
Store backups in secure, geographically separate locations and encrypt them both in transit and at rest. But don’t just back up; test your recovery plans periodically to make sure they work even under pressure.
