adaptive-proxy-sdk

IBM Security Verify Adaptive Proxy SDK for JavaScript

The Proxy SDK for server-side JavaScript (Node). The purpose of this library is to provide an interface for device authentication, authorization, and risk assessment using IBM Security Verify.

Prerequisites

• Configure your IBM Security Verify Tenant.

Installation

Use npm to install the Proxy SDK:

npm install adaptive-proxy-sdk

Configuration Settings

To use the Proxy SDK, you will need to initialise an Adaptive object with a configuration object. The configuration object should contian the following parameters:

Parameter	Type	Description
tenantUrl	string	The base URL of your IBM Security Verify Tenant
clientId	string	The identifier of your Security Verify application
clientSecret	string	The secret for your Security Verify application

See Initialise an Adaptive object for an example.

Context Object

A call to each function in this SDK requires a context object as a parameter. This context object contains information about the user-agent attempting the request, such as a session identifier. This device-related information will be used to assess risk during each request.

The context object should contain the following parameters:

Parameter	Type	Description
sessionId	string	The session ID generated by the user-agent, using an Adaptive client SDK.
userAgent	string	The user-agent, typically obtained from the User-Agent HTTP header.
ipAddress	string	The IP address of the user-agent.
[evaluationContext="login"]	string	The stage in the user-agent for which to perform an evaluation. (Used for continuous assessment throughout the user-agent.) Different "stages" or "contexts" will result in different evaluation results, as configured in the sub-policies of the tenant application's policy. Possible options are "login" (default), "landing", "profile", "resume", "highassurance", "other".

Usage

Import the Proxy SDK

const Adaptive = require('adaptive-proxy-sdk');

Initialise an Adaptive object

const config = {
  tenantUrl: 'https://mytenant.ibmcloudsecurity.com',
  clientId: 'e957e707-c032-4076-98cc-3dcf24db8aed',
  clientSecret: '05UXCBaJgL',
};

const adaptive = new Adaptive(config);

Custom transaction storage

You may also pass in a transactionFunctions object to the Adaptive initialisation, as shown below.

const config = {
  tenantUrl: 'https://mytenant.ibmcloudsecurity.com',
  clientId: 'e957e707-c032-4076-98cc-3dcf24db8aed',
  clientSecret: '05UXCBaJgL',
};

const transactionFunctions = {
  createTransaction: myCreateTransactionFunction,
  getTransaction: myGetTransactionFunction,
  updateTransaction: myUpdateTransactionFunction,
  deleteTransaction: myDeleteTransactionFunction
};

const adaptive = new Adaptive(config, transactionFunctions);

This parameter is optional, in case you would like to handle the storing, retrieving, updating, and deleting of transactions created during the A2 flow in an external database. Otherwise, a default in-memory option is used for handling transactions.

If specified, this object must contain four parameters:

• createTransaction
  • The function used to create (store) a transaction. This function should take one parameter; a transaction Object. It should store the object in a database of choice, indexed by a randomly generated v4 UUID (i.e. the transaction ID). After storing the transaction object associated to a transaction ID, the function should return the transaction ID as a string.
• getTransaction
  • The function used to retrieve stored transactions. This function should take one parameter; a transaction ID string. It should return the transaction Object associated to the given transaction ID.
• updateTransaction
  • The function used to update (i.e. add additional properties to) an existing transaction. This function should take two parameters (in order); a transaction ID string of the transaction to update, and an Object of additional properties to add to the transaction. This function shouldn't return anything.
  • For example, if the existing transaction is

    {
      "userId": "123456"
    }
    

    , and the object passed into this function is

    {
      "name": "John"
    }
    

    , the updated transaction should result in

    {
      "userId": "123456",
      "name": "John"
    }
    

• deleteTransaction
  • The function used to delete an existing transaction. This function should take one parameter; a transaction ID string. The function should remove the transaction associated with the given transaction ID from the database storage. This function shouldn't return anything.

Your storage mechanism of choice should ideally have a time-to-live for the transactions (e.g. 1 hour), to prevent accumulating unused/unfinished transactions.

Assess a policy

Performs the initial grant request to OIDC. This will perform risk assessment on the policy, which will result in either a deny, or requires response.

assessPolicy(context)

Parameter	Type	Description
context	Object	See Context Object.

Responses

• A deny response is received when the policy assessment fails.

  {
    "status": "deny"
  }
  

• A requires response will contain an array of allowed factors, indicating that further verification is required (i.e. first-factor verification must be performed) to receive a token. The possible first factor options are "qr", "fido", and "password". You can use the generateQR, generateFIDO, and evaluatePassword functions respectively to initiate these first factors. A transaction ID will also be returned, which will be used to associate subsequent requests to this initial grant.

  {
    "status": "requires",
    "transactionId": "36a101c7-7426-4f45-ab3c-55f8dc075c6e",
    "allowedFactors": ["qr", "fido", "password"]
  }
  

Example Usage

adaptive.assessPolicy(context)
    .then((result) => {
      res.send(result);
    }).catch((error) => {
      console.log(error);
      res.status(404).send({error: error.message});
    });

Lookup Identity Sources

Lookup identity sources by name. If name not defined then return all password-capable sources.

lookupIdentitySources(context, transactionId, [sourceName])

Parameter	Type	Description
context	Object	See Context Object.
transactionId	string	The transaction ID received in assessPolicy.
[sourceName]	string	(Optional) name of identity source. e.g. "Cloud Directory".

Response

• A response containing an array of identity source objects:

       "type": "ibmldap"
     }
   ]
  

Example Usage

let identitySourceId
adaptive.lookupIdentitySources(context, transactionId, "Cloud Directory")
    .then((result) => {
      identitySourceId = result[0].id;
    }).catch((error) => {
      console.log(error);
      res.status(404).send({error: error.message});
    });

Evaluate a password verification

Attempt to complete a password first-factor verification after receiving a requires status from assessPolicy. This will result in either an allow, deny, or requires response.

Introspect Middleware

This function returns an Express middleware function, which has a signature of (req, res, next) => (). This middleware will call the introspect function under the hood, and perform additional checks based on the configuration object. If token introspection succeeds, the next middleware will be called in the stack. If an error occurs during token introspection, the error will be passed to the next() function. You may write your custom error handler middleware to catch the error, and handle it accordingly.

A successful introspection result is cached to save on expensive introspection calls for subsequent requests.

introspectMiddleware([config])

Parameter	Type	Description
[config]	Object	The configuration settings used for the token introspection middleware.
[config.cacheMaxSize=0]	number	The maximum size of the cache, i.e. the maximum number of successful token introspection responses to cache. If the cache becomes full, the least-recently-used introspection result will be removed. A value of 0 means no maximum size, i.e. infinity. This value is ignored after first initialisation (i.e. after first call to function). Default value is 0.
[config.cacheTTL=0]	number	The time (in seconds) to cache a successful introspection result for. If a successful token introspection is done, the result will be cached for the period of time provided, to save expensive introspection calls on each subsequent request. A value of 0 will cache the introspect response for the lifetime of the token as provided in the exp property of the introspect response. Default value is 0.
[config.denyMFAChallenge=true]	boolean	A flag indicating whether an introspected token response with a scope of 'mfa_challenge' should be denied. If true, tokens with scope of 'mfa_challenge' will be rejected. If false, the scope of tokens will be disregarded.

Example Usage

// Add the middleware so it's called at every request to a protected endpoint.
// Cache at most 50 successful introspection responses for 15 minutes each.
app.use('/protected', adaptive.introspectMiddleware({cacheMaxSize: 50, cacheTTL: 900, denyMFAChallenge: true}));

// Optionally define a custom error handler, so any errors thrown by previous middleware can be handled.
app.use((err, req, res, next) => {
  console.log(err.message);
  res.sendStatus(403);
});
