Secure, Deliver and Optimize GenAI Apps with F5 Source | Edit on

Class 5: Secure, Deliver and Optimize GenAI ChatBot¶

AI services and applications are a subset of modern applications. Securing AI apps requires a holistic, end-to-end approach. You cannot fully protect AI applications without also securing the underlying web applications and APIs. AI services are powered by APIs, which serve as the backbone of these systems. Securing APIs is critical to maintaining the integrity and reliability of AI services. Below are the 7 key security controls that are essential for ensuring the overall security of modern web applications, API and AI services.

1 - Fundamental about F5 AI Gateway¶

F5 AI Gateway routes generative AI traffic to an appropriate Large Language Model (LLM) or Small Language Model (SLM) backend and protects the traffic against common threats, which includes:

Inspecting and filtering of client requests and LLM responses
Preventing of malicious inputs from reaching an LLM backend
Ensuring that LLM responses are safe to send to clients
Protecting against leaking sensitive information

There are two key components that form an AI Gateway.

AI Core
AI Processor

AI Core¶

A specialized proxy for generative AI traffic that uses one or more processors to enable traffic protection

The AI Gateway core handles HTTP(S) requests destined for an LLM backend. It performs the following tasks:

Performs Authn/Authz checks, such as validating JWTs and inspecting request headers.
Parses and performs basic validation on client requests.
Applies processors to incoming requests, which may modify or reject the request.
Selects and routes each request to an appropriate LLM backend, transforming requests/responses to match the LLM/client schema.
Applies processors to the response from the LLM backend, which may modify or reject the response.
Optionally, stores an auditable record of every request/response and the specific activity of each processor. These records can be exported to AWS S3 or S3-compatible storage.
Generates and exports observability data via OpenTelemetry.
Provides a configuration interface (via API and a config file).

AI Processor¶

Processors are components that a gateway interacts with in order to change the flow of data between an inbound request and an outbound response. Processors are steps (or commands) in a chain. Processors evaluate requests and responses and return a status to the gateway indicating if the requested prompt should proceed. In addition to gating flow, processors may also change the request or response data so that the next item in a processor chain has a different state. For example, an implementation could change the word “cat” to “dog” for every request. There are different categories of processors, listed below.

There are differents type of processors

System Processor

The most common and generic processor. This type of processor handles most of all processing steps that are not concerned directly with scrubbing, filtering, redacting, or scanning prompts and their responses. Examples of system processors:

Logging processor
Backend router processor
Token accounting processor
Caching processor

Detector Processor A detector processor is a processor that specializes in detecting some property of the text provided in a prompt or response. For example, a detector may seek to discover if a given prompt contains protected intellectual property or PII (personally identifiable information)

Editor Processor An editor processor is a processor that specializes in modifying prompts or responses. For example, an implementation of an editor processor may be a redaction processor which would search and find personally identifiable numeric sequences such as social security numbers and then transform them into an anonymized representation like XXX-XX-XXXX.

Understanding AIGW Configuration¶

For details, please refer to official documentation. Here a brief description.

Routes - The routes section defines the endpoints that the AI Gateway listens to and the policy that applies to each of them.

Note

Example shown AIGW listen for /simply-chat endpoint and will use policy ai-deliver-optimize-pol that uses OpenAI schema.

routes:
  - path: /simply-chat
    policy: ai-deliver-optimize-pol
    schema: openai

Policies - The policies section allows you to use different profiles based on different selectors.

Note

Example uses rag-ai-chatbot-prompt-pol policy which mapped to rag-ai-chatbot-prompt profiles.

policies:
  - name: rag-ai-chatbot-prompt-pol
    profiles:
    - name: rag-ai-chatbot-prompt

Profiles - The profiles section defines the different sets of processors and services that apply to the input and output of the AI model based on a set of rules.

Note

Example uses rag-ai-chatbot-prompt profiles which defined the prompt-injection processor at the inputStages which uses ollama/llama3.2 service.

profiles:
  - name: rag-ai-chatbot-prompt
    inputStages:
    - name: prompt-injection
      steps:
        - name: prompt-injection
    services:
    - name: ollama/llama3.2

Processors - The processors section defines the processing services that can be applied to the input or output of the AI model.

Note

Processor definition for prompt-injection

processors:
  - name: prompt-injection
    type: external
    config:
      endpoint: "http://ai-gateway-processors-f5.trust.apps.ai"
      namespace: "f5"
      version: 1
    params:
      reject: true
      threshold: 0.8

Services - The services section defines the upstream LLM services that the AI Gateway can send traffic to.

Note

Example shown service for ollama/llama3.2 (upstream LLM). This is the service that AIGW will send to. Option for executor are ollama, openai, anthropic or http. Endpoint URL is where the upstream LLM API.

- name: ollama/llama3.2
  type: llama3.2
  executor: openai
  config:
     endpoint: 'http://ollama-service.open-webui:11434/v1/chat/completions'
     secrets:
      - source: EnvVar
        targets:
            apiKey: OPENAI_PUBLIC_API_KEY

2 - Deploy F5 AI Gateway¶

cd ~/ai-gateway/aigw-v0.1/charts/aigw

kubectl create ns ai-gateway

kubectl -n ai-gateway create secret generic f5-license \
--from-literal=license=eyJhbGciOiJSUzUxMiIsInR5cCI6IkpXVCIsImtpZCI6InYxIiwiamt1IjoiaHR0cHM6Ly9wcm9kdWN0LmFwaXMuZjUuY29tL2VlL3YxL2tleXMvandrcyJ9.eyJzdWIiOiJGTkktODc3NGE1NzYtYzRmMC00NjdmLTlkZmQtOTFkYTAxNmQyYTAxIiwiaWF0IjoxNzI5NjE2NzQyLCJpc3MiOiJGNSBJbmMuIiwiYXVkIjoidXJuOmY1OnRlZW0iLCJqdGkiOiJkZWVkOWJiMC05MDk3LTExZWYtOWE5Ni0zYmRiNjE5YzM2ZTciLCJmNV9vcmRlcl90eXBlIjoicGFpZCIsImY1X3NhdCI6MTgyNDA3NjgwMH0.mTIkAvGNcqYFRHURnFpm0B_E6DJKoQ8IZCNTS7DV9-iTUdc-tU99CPRjdlF88sd7QhI8ligoQouU979JgLEDLLIHymUTWs3v96APLR7EaFaRhO0BlmKIDGf0cGZWOvSlvUi2Z_75Xbjo5yMy8Kzr3YBznqRtUvF2exBdV94iRAoq3q61k_emOHR8-jtoheHPXBAUU3mQyQLpsj55JRIWbY3c_RKmxLTlM3dGXpUXkyWJHLpUnTS_OU3HGjL9vfCbHrtM0zSPAvhrsWUMDaO6BXUHlFQcwgEyELjbemKNvXK71IjDXR-h_PAaYOVjhiTszQ0_m7a9KMLz1fLHCXm31zdAFZyMChD75SXNGlqB0AhRfmgRQw5bCw7oMVwbC5eZtUMXZMH_sshKNB5NI9weLF8LOzFEe7MoGm2MoaUbxP9Sy7lEE3rqkJgu_tZVvWZwn2XjMQYB0cqGtPnwkPVti10zLLRlucm5yUWNyo-zcimCUl05jqzI-qCK3-G70K2kolqS_7WlXe1kQ5czS4-BLwN4IupS0cCn47qdwkRAVgwLCdN5NJAxkzSZaevequ6aCx-tA0GKg1BnFdMUJeFGeoOSQ5dnCvL2sSofhiok9rJXAzAgXK6QB0ZubsmQOdcHYZ85opSxu-DdOL4fsUcY5dl1uAnGTKoq4-A0uDiuVtU

Install AIGW Core helm charts¶

helm -n ai-gateway install aigw -f values-ai-gateway-base.yaml .

Note

values-ai-gateway-base.yaml is the base aigw.yaml configuration - without any policy configuration. values-ai-gateway.yaml contains configuration with policies. We can either use API to create configuration dynamically or create configuration/policy as part of the deployment. Please do notes that configuration created via API will not survive on reboot or restart. For this class, we will use API to create AIGW configuration.

kubectl -n ai-gateway get po,svc

kubectl -n ai-gateway logs -l app.kubernetes.io/instance=aigw

AIGW Core is running and listening for traffic.

3 - Deploy AI GW User Interface.¶

Attention

This AI GW UI is an interim UI for AI GW. AIGW UI will change in future.

cd ~/ai-gateway/aigw-v0.1/aigw-ui-manifest

kubectl -n ai-gateway apply -f aigw-config.yaml

kubectl -n ai-gateway apply -f ui-deploy.yaml

kubectl -n ai-gateway get po,svc

AIGW UI is running.

Create the following Nginx ingress resource to expose services externally from the Kubernetes cluster.

AIGW core (ingress to LLM for inference)
AIGW configuration service (ingress for AIGW admin configuration via API)
AIGW UI (viewing of the configuration)

Note

For the purpose of subsequent lab (open-webui PII-Redactor), we leverage Nginx mergable ingress resources as we require cross-namespace access from AIGW. Hence, we have xxx-master.yaml and xxx-minion.yaml. Please refer to https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/cross-namespace-configuration/ for details on Nginx mergable ingress resource.

cd ~/ai-gateway/nginx-ingress-aigw

kubectl -n ai-gateway apply -f aigw-ingress-master.yaml

kubectl -n ai-gateway apply -f aigw-ingress-minion.yaml

kubectl -n ai-gateway apply -f ~/ai-gateway/nginx-ingress-open-webui/open-webui-ingress-ollama-minion.yaml

kubectl -n ai-gateway apply -f aigw-config-ingress.yaml

kubectl -n ai-gateway apply -f aigw-ui-ingress.yaml

kubectl -n ai-gateway get ingress

Confirm you can access the AIGW UI from Chrome browser

Note

Currently, no policy configured. Hence, no configuration shown on UI.

4 - Deploy F5 AI Processor¶

Deploy NGINX ingress controller for AI Processor K8S.

cd ~/ai-processor/nginx-ingress

kubectl create ns nginx-ingress

helm -n nginx-ingress install nginxic \
oci://ghcr.io/nginxinc/charts/nginx-ingress -f values.yaml --version 1.4.0

kubectl -n nginx-ingress get po,svc

Note

Ensure all pods are in Running and READY state where all pods count ready before proceed.

Install AIGW processor helm chart¶

cd ~/ai-processor/aigw-v0.1/charts/aigw

kubectl create ns ai-gateway

helm -n ai-gateway install ai-processor -f values-ai-processor.yaml .

kubectl -n ai-gateway get po,svc

Note

Ensure all pods are in Running and READY state where all pods count ready before proceed.

Create an Nginx ingress resource to expose AIGW Processor service externally from the Kubernetes cluster.

cd ~/ai-processor/

kubectl -n ai-gateway apply -f aiprocessor-ingress.yaml

kubectl -n ai-gateway get ingress

5 - Update AIGW policy¶

Import AIGW policy configuration into Postman.

Import into Postman collection. A copy of the postman collection located in Documents folder

Monitor AIGW Core logs.

cd ~/ai-gateway

kubectl -n ai-gateway logs -f -l app.kubernetes.io/name=aigw

From Postman, expand the uploaded collection and select ai-deliver-optimize-default-rag-pii-pol and click Send to create AIGW configuration.

Confirm AIGW policy successfully applied via AIGW UI.

6 - Update LLM Orchestrator to point to AI Gateway¶

Currently, GenAI RAG chatbot pointing to the Ollama API. Update GenAI RAG Chatbot to point to AIGW API endpoint.

We are going to use OpenAI compatible API. We are going to use ChatOpenAI Custom node.

Drag the ChatOpenAI Custom node onto the FlowiseAI canvas.

Here a series of task that you may need to perform.

Create a Connect Credential. We are going to use a dummy account

You need to provide the model name - llama3.2:1b

You need to add the AIGW API endpoint (https://aigw.ai.local/v1) via Additional Parameters. Disable Streaming.

Break the link between ChatOllama with Conversational Retrival QA Chain and connect Conversational Retrival QA Chain to ChatOpenAI Custom node.

Note

You may leave the ChatOllama node without deleting it.

Validate GenAI chatbot works via AIGW

Interact with the GenAI RAG chatbot with an example question like below:-

tell me member of the board of director

Who is chairman of the board

You may need to make multiple queries, as hallucinations can occur. Meanwhile, monitor the AIGW logs to confirm that the GenAI RAG chatbot traffic is successfully passing through the AIGW

7 - Deploy Simply-Chat Apps¶

Simply-Chat is another sample GenAI Chatbot to interact with LLM.

Deploy simply-chat apps to interact with AIGW or LLM.

Create an Nginx ingress resource to expose simply-chat service externally from the Kubernetes cluster.

cd ~/webapps/simply-chat

kubectl create ns simply-chat

kubectl -n simply-chat apply -f simply-chat.yaml

kubectl -n simply-chat apply -f simply-chat-ingress.yaml

kubectl -n simply-chat get po,svc,ingress

Confirm you able to access to simply-chat apps

8 - Use Cases¶

LLM Traffic Management¶

This section will show how AI Gateway can route to respective conditions.

This section will show how to route to respective LLM model based on language and code detection.

If user input code snippet, send to an internally curated private model (codellama) instead of send to public or SaaS-Managed model. E.g. prevent accidental sensitive code leakage.
If user input English language, route to private llama3 model.
If user input Mandarin Chinese, route to private qwen2.5 model from Alibaba Cloud.
If user input Japanese, route to private rakuten-7b-chat model fromm Rakuten.
If none of the above match, route to private Phi3 model from Microsoft.

The following policy are configured on AIGW.
