You Should Know:
- AWS CLI Command to Check S3 Bucket Permissions:
aws s3api get-bucket-acl --bucket your-bucket-name
This command helps you verify the access control list (ACL) for your S3 bucket, ensuring that only authorized users have access.
2. Linux Command to Monitor Network Traffic:
sudo tcpdump -i eth0 -n
Use this command to monitor network traffic on your Linux server, which is crucial for detecting unauthorized access or unusual activity.
3. Windows Command to Check Open Ports:
netstat -an | find "LISTENING"
This command lists all open ports on a Windows machine, helping you identify potential vulnerabilities.
4. AWS CLI Command to List IAM Users:
aws iam list-users
Regularly list IAM users to ensure that only necessary accounts have access to your AWS resources.
5. Linux Command to Check for Rootkits:
sudo rkhunter --check
Run this command to scan your Linux system for rootkits, which can be used by attackers to gain unauthorized access.
6. Windows Command to Check for Active Connections:
netstat -ano
This command shows active connections and their corresponding process IDs, useful for identifying suspicious activity.
- AWS CLI Command to Encrypt an S3 Bucket:
aws s3api put-bucket-encryption --bucket your-bucket-name --server-side-encryption-configuration '{"Rules": [{"ApplyServerSideEncryptionByDefault": {"SSEAlgorithm": "AES256"}}]}'Ensure your S3 bucket is encrypted to protect sensitive data.
8. Linux Command to Check for Open Files:
lsof -i
This command lists all open files and the processes that opened them, helping you identify potential security risks.
9. Windows Command to Check for Scheduled Tasks:
schtasks /query /fo LIST /v
Review scheduled tasks to ensure no malicious tasks are running on your system.
