Full house at the first session of the onsite cloud configuration review workshop 😶🌫️🔥
Huge thanks to ClujHUB for helping the cyber community and hosting these sessions!
More workshops from DEFCON Cluj are in plan so make sure to follow us for catching the next ones!
Thanks to everyone present! 💪
Practice Verified Codes and Commands:
1. AWS CLI Command to List S3 Buckets:
aws s3api list-buckets --query "Buckets[].Name"
This command lists all S3 buckets in your AWS account.
2. Check IAM User Permissions:
aws iam list-user-policies --user-name <USERNAME>
Use this to review permissions assigned to a specific IAM user.
3. Scan for Open Security Groups in AWS:
aws ec2 describe-security-groups --filters Name=ip-permission.cidr,Values='0.0.0.0/0' --query "SecurityGroups[*].GroupId"
This command identifies security groups with open access to the internet.
4. Linux Command to Check Open Ports:
sudo netstat -tuln
Use this to identify open ports on your Linux system.
5. Windows Command to Check Network Connections:
[cmd]
netstat -an
[/cmd]
This command displays active network connections on a Windows machine.
What Undercode Say:
The onsite cloud configuration review workshop organized by DEFCON Cluj highlights the importance of securing cloud environments. Cloud security is a critical aspect of modern IT infrastructure, and workshops like these provide hands-on experience in identifying and mitigating vulnerabilities.
For AWS users, regularly reviewing IAM policies, S3 bucket permissions, and security groups is essential. Commands like `aws s3api list-buckets` and `aws ec2 describe-security-groups` help in auditing your cloud environment. On Linux, tools like `netstat` and `nmap` are invaluable for network security checks. Similarly, Windows users can rely on `netstat` and `PowerShell` commands for monitoring and securing their systems.
To further enhance your skills, explore AWS documentation and Linux man pages for advanced commands. For example, use `man netstat` to learn more about network statistics or `aws help` to explore AWS CLI capabilities.
For those interested in cloud security, consider enrolling in AWS Certified Security Specialty courses or attending DEFCON events. These resources provide in-depth knowledge and practical insights into securing cloud infrastructures.
Remember, cybersecurity is an ongoing process. Regularly update your systems, apply patches, and conduct security audits to stay ahead of potential threats.
