security groups - Auto Scaling: - Elastic Load Balancing (ELB) –IAM: - AWS Security, Working of IAM

Shared Responsibility Model – AWS secures the cloud, customers secure their data
Data encryption at rest and in transit
Network security via Security Groups, NACLs, and VPC

1. Security Groups Acts as a virtual firewall for EC2 instances Controls inbound and outbound traffic Stateful – return traffic is automatically allowed Rules can be defined by IP, protocol, and port

2. Auto Scaling Automatically adjusts the number of EC2 instances Ensures availability and fault tolerance Scales out during high demand, scales in when demand decreases Helps optimize costs by using only required resources

3. Elastic Load Balancing (ELB) Distributes incoming traffic across multiple EC2 instances Improves fault tolerance and application availability Supports health checks to route traffic only to healthy instances Works with Auto Scaling for dynamic resource management

4. Identity and Access Management (IAM) Provides secure access control for AWS services and resources Allows creation of users, groups, and roles Supports fine-grained permission policies Enables multi-factor authentication (MFA) for enhanced security

5. AWS Security Shared Responsibility Model – AWS secures the cloud, customers secure their data Data encryption at rest and in transit Network security via Security Groups, NACLs, and VPC Monitoring and auditing with CloudTrail and CloudWatch Compliance with global security standards (ISO, SOC, GDPR, etc.)

6. Working of IAM (Identity and Access Management) Manages access to AWS services and resources securely Users: Represent individual people or applications Groups: Collections of users with common permissions Roles: Temporary access with specific permissions Policies: JSON documents defining fine-grained permissions Supports MFA for enhanced authentication Follows least privilege principle for security best practices

7. CloudFront: Working Content Delivery Network (CDN) service from AWS Distributes content through a global network of edge locations Routes user requests to the nearest edge location for low latency Caches copies of content at edge locations to improve performance Supports dynamic and static content delivery

8. CloudFront: Benefits Reduced latency and faster content delivery Improved application performance and user experience Highly available and scalable infrastructure Security features like DDoS protection, encryption, and AWS Shield integration Cost-effective by reducing load on origin servers
