Interface Endpoint vs Gateway Endpoint vs Gateway Load Balancer Endpoint

2021-08-31T08:24:23+00:00

Interface Endpoint Gateway Endpoint Gateway Load Balancer Endpoint An elastic network interface with a private IP address that serves as an entry point for traffic destined to a supported AWS service, endpoint service, or AWS Marketplace service. For each interface endpoint, you can choose only one subnet per Availability Zone. Endpoints are regional, which means they are only usable within the same region they are created in. Since interface endpoints use ENIs, they also use security groups to control traffic. Can be accessed through AWS VPN connections or AWS Direct Connect connections, through intra-region VPC peering connections from Nitro instances, [...]

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 [...]

Security Group vs NACL

2021-04-27T02:53:24+00:00

  Your VPC has a default security group with the following rules: Allow inbound traffic from instances assigned to the same security group. Allow all outbound IPv4 traffic and IPv6 traffic if you have allocated an IPv6 CIDR block. Your VPC has a default network ACL with the following rules: Allows all inbound and outbound IPv4 traffic and, if applicable, IPv6 traffic. Each network ACL also includes a non modifiable and non removable rule whose rule number is an asterisk. This rule ensures that if a packet doesn't match any of the other numbered rules, it's denied. [...]
