# AWS Cloud Security Essentials
2+
3+
A curated collection of checklists, best practices, and practical guides for securing Amazon Web Services (AWS) environments. This repository is specifically designed for cloud security professionals, DevOps engineers, and compliance auditors.
4+
5+
## 📋 Overview
6+
7+
AWS Cloud Security refers to the practices, technologies, and policies implemented to protect cloud-based systems, data, and infrastructure on Amazon Web Services. This repository provides practical resources for implementing and auditing security controls across various AWS services, helping organizations maintain a strong security posture in accordance with the AWS Shared Responsibility Model .
8+
9+
## 🛡️ Key AWS Security Domains
10+
11+
Based on AWS's security framework and best practices, this repository covers these essential domains :
12+
13+
- **Identity and Access Management (IAM)** - Secure management of identities, resources, and permissions
14+
- **Data Protection** - Encryption, key management, and sensitive data discovery
15+
- **Threat Detection and Response** - Continuous risk identification and prioritization
16+
- **Network and Application Protection** - Implementing detailed security policies at network control points
17+
- **Compliance** - Automated compliance checks based on AWS best practices and industry standards
18+
19+
## 🔍 AWS Security Checklist Highlights
20+
21+
### IAM & Access Control
22+
- [ ] Enable multi-factor authentication (MFA) for all users
23+
- [ ] Follow the principle of least privilege for all policies
24+
- [ ] Regularly rotate access keys and review permissions
25+
- [ ] Use IAM roles instead of long-term access keys when possible
26+
27+
### Data Protection
28+
- [ ] Enable encryption at rest for EBS volumes, S3 buckets, and RDS instances
29+
- [ ] Use AWS KMS for key management with automatic rotation
30+
- [ ] Classify data based on sensitivity and apply appropriate protections
31+
- [ ] Implement SSL/TLS for data in transit
32+
33+
### Monitoring & Logging
34+
- [ ] Enable AWS CloudTrail for API activity logging across all regions
35+
- [ ] Configure AWS Config for resource inventory and change tracking
36+
- [ ] Set up Amazon GuardDuty for threat detection
37+
- [ ] Establish log retention policies according to compliance requirements
38+
39+
### Network Security
40+
- [ ] Implement security groups with minimal open ports
41+
- [ ] Use Network ACLs for additional subnet-level protection
42+
- [ ] Enable VPC Flow Logs for traffic monitoring
43+
- [ ] Secure Site-to-Site VPN connections with appropriate tunneling protocols
44+
45+
### Backup & Recovery
46+
- [ ] Enable automated backups for critical resources (RDS, EBS, etc.)
47+
- [ ] Test restoration procedures regularly
48+
- [ ] Implement versioning and MFA delete for S3 buckets
49+
- [ ] Establish Recovery Time Objective (RTO) and Recovery Point Objective (RPO) targets
50+
51+
