IP Blocking: Use AWS WAF or NACL?

2023-08-14T02:45:24+00:00

What should you do if you identified a series of malicious attacks on your application coming from a specific IP address? Will you use AWS WAF to block that IP address or create a rule in your Network Access Control List to deny traffic from that IP? It is true that AWS WAF can filter web requests based on IP addresses, HTTP headers, HTTP body, or URI strings, to block common attack patterns, such as SQL injection or cross-site scripting. NACL, on the other hand, acts like a firewall for controlling traffic in and out of your subnets. If the [...]

Longest Prefix Match: Understanding Advanced Concepts in VPC Peering

2023-08-14T02:40:31+00:00

VPC Peering Basics In AWS, a Virtual Private Cloud (VPC) peering connection is a networking connection between two VPCs which allows you to route specific traffic between them using either private IPv4 addresses or IPv6 addresses. A VPC peering connection can be created between your own VPCs, or alternatively, a VPC in another AWS account. You can also create an inter-region VPC peering connection where the VPCs are located in different AWS Regions. Amazon EC2 Instances in either VPC can communicate with each other freely as if they are within the same network. One example of VPC Peering is the [...]

How to invalidate API Gateway Cache

2021-05-03T13:34:08+00:00

To invalidate an existing cache entry of a request and retrieve the latest data from the integration endpoint, one must send the request together with the Cache-Control: max-age=0 header. If the recipient is authorized to communicate directly to the integration endpoint, then the integration endpoint will respond with the latest data for the request. This also replaces the existing cache entry with the new response. The IAM Policy that grants a client to invalidate the cache follows: {   "Version": "2012-10-17",   "Statement": [     {       "Effect": "Allow",       "Action": [         "execute-api:InvalidateCache"       ],       "Resource": [ "arn:aws:execute-api:region:account-id:api-id/stage-name/GET/resource-path-specifier"       ]     }   ] }    An alternative option [...]

Top 5 Free AWS Review Materials

2021-06-26T13:32:00+00:00

Currently, the cost of an AWS Certification exam starts from 150 USD for associate-level exams and up to a whopping 300 USD for professional-level and specialty-type exams. For some, this amount is negligible but to many IT professionals around the world, this amount is relatively expensive. The official AWS Practice Exam ranges from 20 to 40 USD, which you can only take once (unless you shell out another $20 or $40 again in order to retake it). On top of it, there are a lot of people who subscribe to online cloud learning providers which can range from $30 to $38 per month or [...]

Calculating the Required Read and Write Capacity Unit for your DynamoDB Table

2021-05-04T09:10:25+00:00

Read Capacity Unit On-Demand Mode When you choose on-demand mode, DynamoDB instantly accommodates your workloads as they ramp up or down to any previously reached traffic level. If a workload’s traffic level hits a new peak, DynamoDB adapts rapidly to accommodate the workload. The request rate is only limited by the DynamoDB throughput default table limits, but it can be raised upon request. For on-demand mode tables, you don't need to specify how much read throughput you expect your application to perform. DynamoDB charges you for the reads that your application performs on your tables in terms of read request [...]
