- The outbound rules block UDP port 53, so the server will not be able to resolve any DNS lookups.
- The outbound rules do not allow for HTTP traffic to leave the instance, so inbound HTTP requests will fail because the clients will never get HTTP responses.
- The incoming SSH port should not be open to the public. Limit SSH to a single IP address or IP range of controlled addressed, or use a VPN to access the VPC for this server.
- The all incoming TCP ports are exposed, which overrides the HTTP and SSH rules and exposes all TCP ports to the public internet.
