The increasing number of companies transitioning into cloud based services has brought about an increased need for companies to prioritize cloud cybersecurity. The many benefits of cloud services such as scalability, flexibility and cost-effectiveness bring with them various unique cybersecurity risks. In this article we examine the importance of cloud cybersecurity, and provide some ideas for how businesses can take action to protect themselves from these risks.
1. Be aware of the Shared Responsibility Model
Security in cloud computing is a joint responsibility between the cloud service provider and the customer. While cloud service providers are generally responsible for the security of the underlying physical hardware, network and virtualization layers, customers are responsible for ensuring the security of their own data, applications, and access controls within the cloud environment.
Shared responsibility model key considerations:
Cloud Service Provider’s Security Responsibilities:
- Physical Infrastructure Security
- Network Security
- Hypervisor Layer Security
Customer’s Security Responsibilities:
- Customer is responsible for securing data
- Customer is responsible for managing access controls
- Customer is responsible for encrypting sensitive information
Industry Regulations & Standards Compliance Requirements:
- Customer must ensure compliance of security policies with relevant industry regulations and standards.
A customer who understands their role in the shared responsibility model can make better decisions regarding their own security responsibilities.
2. Utilize Strong Identity and Access Management (IAM) Practices
Access control is one of the most important aspects of cloud security. A strong Identity and Access Management (IAM) system is required to control access to your cloud resources, to help you protect sensitive information, and to allow only those who should be able to access your resources to do so.
Identity and Access Management (IAM) Best Practices:
- Multi-Factor Authentication (MFA): Multiple types of authentication such as passwords and biometric methods should be used to improve the strength of access security.
- Least Privilege Principle: Users should have access to the least amount of data and functions that are needed for them to perform their job.
- Periodic Review of Access Permissions: Customers should periodically review access controls to ensure that permissions are current and consistent with user roles.
Use of a strong IAM system can help minimize the risk of unauthorized access, and mitigate the threat of insider attacks.
3. Encrypt Your Data
Protecting sensitive information in the cloud is one of the most important priorities for organizations. Using encryption is one of the best ways to protect sensitive information. When you use encryption, you can prevent unauthorized access to your data because it is unreadable without the proper decryption keys.
Data Encryption Strategies:
- Data Encryption At Rest: Customers must ensure that data is encrypted when it is stored in the cloud, especially if the data is stored on shared infrastructure.
- Data Encryption In Transit: Customers must use encryption protocols, such as SSL/TLS, to protect data during transmission across networks.
- Key Management: Customers must implement a strong method for managing encryption keys, and to ensure that the keys are securely stored.
Encryption provides an additional layer of protection for your organization’s sensitive information by preventing unauthorized access to your data, and minimizing the risk of data breaches.
4. Regularly Update and Patch Your Cloud-Based Systems
Cyberattackers are constantly looking for vulnerabilities in older versions of software and systems to exploit. Updating and patching your cloud-based systems regularly can help to eliminate vulnerabilities that could lead to cyberattacks.
Best Practices for Update and Patch Management:
- Automatic Updates: Enable automated updates for security patches to quickly address vulnerabilities.
- Testing Patches Before Deployment: Test patches thoroughly in a staging environment to avoid disrupting your systems.
- Continuous Monitoring of Vulnerabilities: Monitor continuously for new vulnerabilities and deploy patches as quickly as possible after they are released.
By keeping your cloud systems updated and patched, you can continue to protect your organization against emerging threats.
Conclusion
Cloud cybersecurity is important for protecting sensitive data and maintaining the integrity of your organization’s cloud-based operations. Organizations can create secure cloud environments by understanding the shared responsibility model, creating a strong IAM system, utilizing encryption, and regularly updating their cloud-based systems. As cloud adoption continues to grow, maintaining the same high-level of cybersecurity practices will be essential to continuing to protect digital assets.
