Get it covered: 7 essential practices for AWS security

14/07/2023 Andy Mommerency

In today’s ever-changing threat landscape, cloud security cannot be emphasized enough. Although the AWS platform provides organizations with a dependable, scalable and cost-effective solution for storing and processing sensitive data, organizations must implement their own AWS security best practices as part of the shared responsibility model. Here are seven crucial practices that can help you secure your cloud infrastructure and mitigate the risk of security breaches:

#1 Develop a comprehensive strategy

Before deploying your applications on AWS, it is essential to establish a well-defined cybersecurity strategy. This strategy should include conducting a risk assessment, performing threat modelling, and devising a mitigation plan. Identify potential risks and vulnerabilities specific to your cloud infrastructure and implement measures to address them. This will ensure compliance with industry standards and regulations while proactively preventing cyberattacks.

#2 Become familiar with the AWS Well-Architected Framework

AWS offers abundant resources to help organizations enhance their security posture. The AWS Well-Architected Framework provides guidance for designing and operating secure and cost-effective systems in the cloud. The Framework encompasses five key pillars: operational excellence, security, reliability, performance efficiency, and cost optimization. Understanding and leveraging the Framework is key to safeguarding applications against potential cyberthreats.

#3 Implement robust security controls

Taking proactive measures to impose strong cloud security controls is crucial for organizations to secure their AWS cloud infrastructure effectively. As the responsibility falls on you to protect your cloud workloads, consider implementing security controls to minimize the risk of security breaches, including clearly defining user roles, conducting privilege audits, enforcing a strong password policy, and using multi-factor authentication (MFA). Consistent enforcement and adherence to these security controls throughout your organization are essential.

#4 Ensure easy access to security policies

Accessibility to your AWS security policies is key to promoting a culture of security within your organization. These policies should encompass access control, network security, encryption, and incident response guidelines. Making policies accessible helps everyone in your organization understand the importance of security and act in accordance with your policies.

#5 Safeguard data with encryption

Encrypting your data prevents unauthorized access and ensures its confidentiality, even if intercepted or stolen. Encryption is often mandatory for regulatory compliance. AWS provides various encryption options, including server-side encryption, client-side encryption, and transit encryption. Familiarize yourself with these options and choose the appropriate method to secure your sensitive data within your cloud environment.

#6 Back up data consistently

Regular data backups ensure data integrity and availability. In the event of cyberattacks, hardware failures, or accidental deletions, having up-to-date backups provides peace of mind and enables data recovery. The frequency of backups should be based on the criticality and volatility of your data. Regulatory requirements and business needs will determine how long the data will be retained. AWS offers various backup options, such as Amazon EBS, Amazon S3, and AWS Backup. By leveraging these options, you can store your backups in multiple regions to ensure constant protection.

#7 Stay up to date

AWS regularly releases security patches, bug fixes, and updates to address vulnerabilities and counter new threats. Keeping your AWS systems up to date maintains the security of your environment and protects against potential attacks. Take advantage of AWS’s automatic update features, such as Amazon Inspector and AWS Systems Manager, to automate patching and ensure your systems are always current. Configure notifications to receive alerts about new updates, enabling prompt action to stay ahead of security risks.
