cloud infrastructure security best practices

A comprehensive cloud infrastructure security includes a broad set of technologies, policies, and applications. It involves security measures that help identify and mitigate vulnerabilities that could prove to be security threats to the cloud infrastructure. These measures also help business continuity by eliminating security issues and supporting regulatory compliance across multiple cloud infrastructures. Though cloud services offer many benefits for business operations, 96% of organizations have faced severe challenges while implementing cloud strategies. As per IBM, 82% of beaches that occurred were for data stored in the cloud. This shows the severity and necessity of cloud security. This blog will explain everything you need to know about cloud infrastructure security, including best practices and possible challenges organizations face with cloud services. What is Cloud Infrastructure Security? Cloud infrastructure security secures cloud resources and supporting systems from internal and external attacks. It involves several procedures, technologies, and guidelines that protect applications and sensitive data stored in cloud infrastructures. Cloud security prevents data breaches and unauthorized access by focusing on authentication and limiting authorized users’ access to resources. 3 Types of Cloud Security: Depending on the type of cloud model used, specific cloud infrastructure security measures are primarily the responsibility of the cloud service provider (CSP) or the user. However, maintaining the integrity of the cloud environment is not the sole responsibility of one party. Cloud service providers and their users work together to implement best security practices to avoid attacks on cloud data, services, and applications. This is briefly mentioned in the shared responsibility model. “Also Read: Cloud Penetration Testing: The Complete Guide Why is Cloud Infrastructure Security Important? More than 92% of organizations use cloud computing. As cybercriminals become more tech-savvy, new and unique cyber threats are being used to target a costly cloud attack. This could compromise sensitive data and the business’s reputation. Cloud computing gives companies a lot of benefits, such as: However, due to several risks like misconfiguration and lack of encryption, cloud infrastructure is prone to significant cyberattacks. With cloud infrastructure security, you can enhance the protection of cloud data and applications and avoid unauthorized access and data breaches. Benefits of Cloud Infrastructure Security Implementing the best cloud security practices offers the cloud service providers and the user a lot of benefits, such as:     You May Like: Everything About Cloud Application Security Testing The Need for Cloud Infrastructure Security: Latest Cloud Security Challenges Organizations looking to enhance their cloud infrastructure security can expect to face these common challenges:   1. Operation Complexity Cloud management requires certain solutions to access public and private providers, platforms, and deployments. This complicates the efficiency of business operations. Integrating every cloud security measure smoothly can be difficult to achieve. 2. Limited Visibility Cloud solutions might not offer as much visibility as on-premises setups. When relying on third-party security solutions, transparency can decrease, which may impact the organization’s control over data and operations. 3. Misconfigurations Lack of knowledge and expertise may lead to misconfigurations, which can potentially lead to data breaches and security vulnerabilities. For example, inadequate privacy settings configuration or failure to update administrative passwords may pose significant risks to data security. 4. Multi-Cloud or Hybrid Cloud Using multiple cloud services from different providers or combining cloud and on-premises solutions creates difficulties while implementing security measures across these different environments.  5. Changing Workloads Managing fluctuating workloads is a big challenge in cloud management. This becomes an issue when cloud services are not designed to adapt to these changes. 6. Shared Responsibility Confusion To maintain cloud security, there are different responsibilities for cloud service providers (CSPs) and the users. Usually, the users are not well-educated with their part. This can create confusion, potential security gaps, and even compliance issues. 7. Insecure Access Hackers are always looking for weak points in the public cloud (SaaS, IaaS, PaaS) to exploit and interfere with operations. This is especially risky for those companies that allow cloud access from all devices and locations. 8. Vendor Lock-In Relying on the security tools of one cloud provider can make it challenging to implement advanced security measures or migrate to other platforms. Cloud Infrastructure Security Best Practices Cloud infrastructure is easier than you think – as long as you do your part. Organizations can protect their cloud infrastructure by implementing the following cloud security best practices. Although these security measures might not prevent every attack, they help businesses enhance their defenses, protect their data, and maintain their reputation.   1. Understand your Shared Responsibility Model Public cloud security differs a lot from private data centers. In the cloud, customers hold the responsibility to protect their data and applications, yet providers also share some duties in a shared responsibility model. Leading cloud providers like AWS and Azure clarify specific roles in their documentation. To ensure security, customers/users must follow encryption and configuration guidelines provided by the cloud vendor. 2. Ask Detailed Security Questions to Your Cloud Provider To ensure cloud security, businesses must ask detailed questions to their public cloud providers. Leading providers may have different security measures. You should ask questions regarding: 3. Implement Identity and Access Management (IAM) Solution To enhance the security of public cloud infrastructure, organizations should implement identity and access management (IAM). Implementing principles like least privilege and zero trust ensures restricted access, while Privileged Access Management (PAM) secures sensitive accounts. Role-based access control (RBAC), multi-factor authentication (MFA), and cross-platform IAM solutions further enhance the security measures. 4. Secure your Endpoints As endpoints directly connect to the cloud, their security should be a top solution. New cloud projects require new security strategies to counter changing threats. Implement Endpoint security measures that include: You can use automated tools like Endpoint Detection and Response (EDR) and Endpoint Protection Platforms (EPP). Additionally, implement patch management, endpoint encryption, VPNs, and insider threat prevention for further security enhancement. 5. Encrypt Data in Motion and At Rest Encryption plays a vital role in any cloud security strategy. Data stored in public cloud services and during transit should be encrypted
