Abstract: A security gateway (360, 460) for validating ingress traffic in a computer network system, and a method for validating the same. The security gateway (360, 460) includes a proxy server (220, 320, 420) and a gateway agent (340, 440). The proxy server receives the ingress traffic and/or the response and forwards the ingress traffic and/or the response to the gateway agent (340, 440). The gateway agent (340, 440) validates the ingress traffic and/or the response as valid ingress traffic and/or valid response or invalid ingress traffic and/or invalid response based on predetermined validation requirements. The proxy server further receives the valid ingress traffic from the gateway agent and forwards the valid ingress traffic to a backend service and/or receives the valid response from the gateway agent and forwards the valid response to a client device or blocks the invalid ingress traffic and/or invalid response.
