Securing resources on Amazon Web Services (AWS) forms a significant portion of the responsibilities you have as an AWS Certified Cloud Practitioner (CLF-C02). AWS provides a whole suite of security services, such as Amazon Inspector, AWS Security Hub, Amazon GuardDuty, and AWS Shield. These services assist organizations in protecting their AWS environments and fulfilling their security and compliance objectives.
1. Amazon Inspector:
Amazon Inspector is an automated security assessment service that improves the security and compliance of applications deployed on AWS. It evaluates applications for potential vulnerabilities or deviations from best practices, including exposure, poor security configurations, weak security practices, and non-compliance with selected compliance standards.
To use Amazon Inspector, you will simply need to set up an assessment target (which includes the EC2 instances you want to assess) and a timeline for the assessment. Amazon Inspector then generates a detailed report of potential security findings, each given a severity rating, to help you prioritize the remediation process.
2. AWS Security Hub:
AWS Security Hub provides a comprehensive picture of your high-priority security alerts and compliance status across AWS accounts. With Security Hub, you have a single location that aggregates, organizes, and prioritizes your security alerts, or ‘findings’ from multiple AWS services, like Amazon Inspector and GuardDuty, along with from AWS Partner solutions.
To use AWS Security Hub, you activate it in your chosen AWS account and region. Then, enable the security services that you want to consolidate findings from. These findings are then sent to Security Hub where they are aggregated into a centralized view.
3. Amazon GuardDuty:
Amazon GuardDuty is a threat detection service that continuously monitors for malicious or unauthorized behavior to help protect your AWS accounts and workloads. GuardDuty identifies unusual or unauthorized activity, such as cryptocurrency mining, credential compromise behavior, communication with known command and control servers, or API calls from known malicious IPs.
You can enable GuardDuty within the AWS Management Console. Once enabled, GuardDuty immediately begins analyzing continuous streams of account and network activity in your AWS environment. It then generates detailed and actionable security findings.
4. AWS Shield:
AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards applications running on AWS. AWS Shield provides always-on detection and automatic inline mitigations to minimize application downtime and latency, thus ensuring the availability of your applications.
For basic DDoS protection, simply using services like Amazon CloudFront or Amazon Route 53 will automatically protect your applications under AWS Shield. For more advanced DDoS protection and cost protection, you may consider AWS Shield Advanced.
Understanding AWS Security Services
Understanding how and when to use these services will form a critical part of the AWS Certified Cloud Practitioner (CLF-C02) exam. It’s recommended to have hands-on experience with each of these services and understanding their core features as well as their contexts of use.
Securing your resources on AWS isn’t always straightforward, but services such as Amazon Inspector, AWS Security Hub, Amazon GuardDuty, and AWS Shield make it more manageable and automated process. These tools help you maximize your applications’ security and minimize your vulnerability, making them a valuable addition to your toolkit as you study for your AWS Certified Cloud Practitioner (CLF-C02) exam.
