S3 access logs are log files generated by Amazon S3 (Simple Storage Service) that capture detailed information about access and requests made to S3 buckets. These logs provide valuable insights into who accessed the buckets, what operations were performed, and when they occurred. S3 access logs can be enabled for individual buckets and are stored in another S3 bucket designated to store the logs.

S3 Pre-Signed URLs
A Presigned URL, also known as a “pre-signed URL,” is a time-limited URL that provides temporary access to a specific resource or operation in a web application. In the context of Amazon S3 (Simple Storage Service), a Presigned URL allows users to grant time-limited, secure access to private objects stored in S3 buckets.
When generating a Presigned URL, the owner of the resource (typically an S3 object) includes a signature with the URL. This signature is generated using the owner’s AWS security credentials, such as access key and secret access key, and it verifies the authenticity and integrity of the URL. The Presigned URL also contains the necessary information about the desired operation, such as GET or PUT, and the expiration time for the URL.
S3 Encryption
Data security is a critical concern for businesses when storing and transmitting sensitive information. Amazon S3 (Simple Storage Service) offers robust encryption mechanisms to ensure the confidentiality and integrity of data stored in the cloud. S3 encryption provides multiple layers of protection, allowing users to encrypt data at rest and in transit.
By employing encryption techniques, businesses can mitigate the risk of unauthorized access and data breaches, ensuring that their data remains secure and compliant with industry regulations. In this introduction, we will explore the different encryption options available in S3 and how they can be utilized to safeguard data stored in the cloud.
Intro to NACL and Security Groups
A Network Access Control List (NACL) is a security feature in Amazon Web Services (AWS) that acts as a virtual firewall for controlling inbound and outbound traffic at the subnet level within a Virtual Private Cloud (VPC). NACLs are stateless, meaning they don’t keep track of the connection state like stateful firewalls do. They evaluate traffic based on rules that you define and allow or deny traffic accordingly.
Network Access Control Lists (NACLs) and Security Groups are both important components of network security in Amazon Web Services (AWS). They provide different levels of control and operate at different layers of the networking stack.
Introduction to AWS Monitoring
AWS monitoring services are essential for maintaining the performance, availability, security, and cost-effectiveness of your AWS infrastructure. They provide real-time insights, automate monitoring and alerting, assist in troubleshooting, and enable proactive management of your resources, leading to optimized operations and improved customer experiences.
Intro to AWS Route 53
Route 53 is a highly scalable and reliable domain name system (DNS) service offered by Amazon Web Services (AWS) that translates domain names into IP addresses to locate resources on the internet. It offers several features such as integration with other AWS services, a global network of DNS servers, DNS traffic flow management, routing policies, health checks, and DNSSEC.
These features enable users to manage their domain names and routing traffic globally, improve application performance and availability, and provide cryptographic authentication and integrity for DNS data. Overall, Route 53 is a comprehensive and popular choice for managing domain names and routing traffic within the AWS environment.
Intro to AWS Elastic Load Balancing
AWS Application Load Balancer (ALB) is a service that provides advanced load balancing capabilities for HTTP and HTTPS traffic at the application layer (Layer 7) of the OSI model. ALB routes incoming traffic to different targets, such as Amazon EC2 instances, ECS tasks, or Lambda functions, based on rules that you define.
Intro to AWS Security Groups
AWS Security Group is a virtual firewall that controls inbound and outbound traffic for Amazon Elastic Compute Cloud (EC2) instances and other resources in Amazon Web Services (AWS). It acts as a virtual firewall that regulates traffic based on rules that you define.
Each AWS Security Group is associated with one or more instances, and you can specify the inbound and outbound traffic rules for that group. You can use security groups to allow or deny traffic from specific IP addresses, protocols, or ports. You can also create rules that allow traffic from other security groups, enabling you to control access to different resources within your VPC.
