AWS VPC Security
What are the primary components of AWS VPC security?
The primary components of AWS VPC security include network security controls such as security groups and network access control lists (NACLs), data encryption, identity and access management (IAM), monitoring and logging, DDoS protection, compliance, and governance.
What is a security group in AWS VPC?
A security group acts as a virtual firewall for controlling inbound and outbound traffic to AWS resources, such as EC2 instances, within a VPC. It allows you to define rules that permit or deny traffic based on port, protocol, and source/destination IP addresses.
How do security groups differ from NACLs in AWS VPC?
Security groups control traffic at the instance level, whereas NACLs control traffic at the subnet level. Security groups are stateful, meaning they automatically allow return traffic, while NACLs are stateless and require explicit rules for both inbound and outbound traffic.
How do I encrypt data in transit and at rest within an AWS VPC?
You can encrypt data in transit using SSL/TLS for communication between resources within the VPC and external endpoints. For data at rest, you can use AWS Key Management Service (KMS) to manage encryption keys and encrypt data stored in AWS services such as Amazon S3, Amazon EBS, and Amazon RDS.
What are some best practices for securing an AWS VPC?
Some best practices for securing an AWS VPC include implementing least privilege access controls, regularly reviewing and updating security groups and NACLs, encrypting sensitive data, enabling logging and monitoring, conducting security assessments and audits, and staying informed about AWS security best practices and updates.
