The AWS Security Learning Path by Let’s Defend is an excellent resource for mastering cloud security fundamentals and AWS-specific tools. This course dives deep into key AWS security services such as GuardDuty, CloudTrail, WAF, and CloudWatch, providing hands-on experience through practical labs and exercises.
Key AWS Security Services Covered:
- GuardDuty: A threat detection service that continuously monitors for malicious activity and unauthorized behavior.
– Command to enable GuardDuty:
aws guardduty create-detector --enable
– Check findings:
aws guardduty list-findings --detector-id <detector-id>
- CloudTrail: Tracks API activity and provides a history of AWS account actions.
– Create a new trail:
aws cloudtrail create-trail --name MyTrail --s3-bucket-name my-bucket --is-multi-region-trail
– View trail logs:
aws s3 ls s3://my-bucket/AWSLogs/<account-id>/CloudTrail/
- WAF (Web Application Firewall): Protects web applications from common exploits.
– Create a WAF Web ACL:
aws wafv2 create-web-acl --name MyWebACL --scope REGIONAL --default-action Allow
– Associate WAF with a resource:
aws wafv2 associate-web-acl --web-acl-arn <web-acl-arn> --resource-arn <resource-arn>
- CloudWatch: Monitors AWS resources and applications in real-time.
– Create a CloudWatch alarm:
aws cloudwatch put-metric-alarm --alarm-name MyAlarm --metric-name CPUUtilization --namespace AWS/EC2 --statistic Average --period 300 --threshold 80 --comparison-operator GreaterThanOrEqualToThreshold --dimensions Name=InstanceId,Value=<instance-id> --evaluation-periods 2 --alarm-actions <sns-topic-arn>
– View CloudWatch logs:
aws logs filter-log-events --log-group-name /aws/lambda/my-function --start-time <timestamp> --end-time <timestamp>
Practical Implementation:
- IAM Role and Policy Configuration:
aws iam create-role --role-name MyRole --assume-role-policy-document file://trust-policy.json aws iam put-role-policy --role-name MyRole --policy-name MyPolicy --policy-document file://policy.json
Testing Detections with GuardDuty:
Simulate threats using tools like `Pacu` or manually trigger suspicious activities to test GuardDuty’s detection capabilities.

For those looking to deepen their understanding, consider exploring additional Linux and Windows commands to complement your AWS security skills:
– Linux Commands:
– Monitor network traffic: `tcpdump -i eth0`
– Check open ports: `netstat -tuln`
– Analyze logs: `grep “error” /var/log/syslog`
– Windows Commands:
– Check active connections: `netstat -an`
– View event logs: `Get-EventLog -LogName Security`
– Test network connectivity: `Test-NetConnection -ComputerName
