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 [...]

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 [...]
