IGI Default Entitlements

Monday, 27 February 2017
Those of you who have downloaded the latest (and greatest) version of IBM Security Identity Governance (v5.2.2) are no doubt having a wonderful time with the new interface and the new features.

But like every new software release, one or two things may not behave quite like you expected them to.

As an example, the rule embedded within the USER_MOVE Rule Flow suggests that the moveUser method will move a user to a new Organisational Unit and automatically assign all default entitlements assigned to that OU. At least, the comments explicitly state that this is to be expected:

// Move the user assigning the default entitlements of the new OU
UtilAction.moveUser(sql, userBean, orgUnitBean);

Unfortunately, the result of this operation is somewhat disappointing. The user does indeed move... but new default entitlements are not assigned.

Checking a v5.2.1 demo image that I have, though, reveals the following additional code which does actually meet our expectations:

// Assign default entitlements of OU
EntitlementBean entBeanDefault = new EntitlementBean(); 
entBeanDefault.setDefaultOption(true);

BeanList entsDefault = _OrgUnitAction.findEntitlementByOU(sql, false, entBeanDefault, null, orgUnitBean, null);
if (!entsDefault.isEmpty()) {
    for (int k = 0; k < entsDefault.size(); k++) {
        EntitlementBean role = (EntitlementBean) entsDefault.get(k);
        BeanList roles = JobRoleAction.find(sql, role);
        if(roles==null || roles.isEmpty() ) {
            throw new Exception("Role : " + role.getName() + " not found!");
        }
        UserAction.addRole(sql, userBean , orgUnitBean , roles , null, null, false, false);
    }
}

NOTE: The following will need adding to the Package Imports:
import com.engiweb.profilemanager.common.ruleengine.action.reorganize._OrgUnitAction
import com.engiweb.profilemanager.common.ruleengine.action.JobRoleAction

IGI Attribute Hierarchies

Tuesday, 22 November 2016
IBM Security Identity Governance & Intelligence (or IGI for short) has a very neat feature whereby hierarchies can be constructed using any attribute associated with an identity. Now, instead of identities being firmly placed within a rigid organizational hierarchy, additional hierarchies can be created to help model entitlements more accurately.

For example, it could be useful for everyone who reports to a specific manager to be automatically assigned a suite of entitlements. Additionally, we could find that rights should be assigned based on regional or office location.

Fundamentally, the assignment of this rights is somewhat akin to how IBM Security Identity Manager could be configured with dynamic roles - except IGI's approach is so much more powerful.

For example, let's consider identity records that contain the following attributes:

  • Country
  • City
  • Address

It could be interesting to model that hierarchy and "virtually" place identities in a hierarchy that might look like this:

World
- United Kingdom
- - Belfast
- - - 1 Main Street
- - London
- - - 2 High Street
- - - 3 Oxford Street
- - - 4 Piccadilly
- France
- - Paris
- - - 5 Rue de Provence

etc.

Modelling the hierarchy is simple. As an IGI administrator, one merely needs to navigate to Access Governance Core > Configure > Rules. In here, we can create a Rules Sequence called  LOCATION_HIERARCHY of type Hierarchy.

Now, within the Rules tab, we can select the rule class Hierarchy and rule flow LOCATION_HIERARCHY (ignoring the fact that the naming convention mismatch between sequence and flow is rather annoying).

Within the package imports section, we would place the following:

import com.engiweb.profilemanager.common.bean.UserBean
import com.crossideas.certification.common.bean.data.ResultBean
import com.engiweb.profilemanager.common.ruleengine.action.UtilAction
import java.util.ArrayList

global com.engiweb.pm.dao.db.DAO sql
global com.engiweb.logger.impl.Log4JImpl logger

This suite of imports exposing methods which we can now use. Our next step is to CREATE a Rules Package with the following code:

when
    userBean : UserBean(  )  
    resultBean : ResultBean(  )
then
/* Country>City>Office */
    String country = userBean.getCountry();
    String city = userBean.getLocality();
    String office = userBean.getAddress();

    if (country != null && city != null && office != null) {
        resultBean.setResultString("World;" + country + ";" + city + ";" + office); 
    } else {
        resultBean.setResultString("World"); 
    }

What does this code do? Well, it iterates over every identity in the platform and constructs a string of World;Country;City;Office which can be passed back to the core platform in order to construct a hierarchy. Give the package a "sensible" name (like Country>City>Office) and assign it to the LOCATION_HIERARCHY rule flow.

The next step is to Access Governance Core > Configure > Hierarchy in order to create a hierarchy that can use our rule flow. Under the Actions link, click on Add. Populate the blank form with the following details:

Name: Location Hierarchy
Configuration Type: Advanced
Rule: LOCATION_HIERARCHY
Value: Hierarchy
Separator Char: Semi-Colon (;)

Save the hierarchy, re-select it and under Actions, click on BUILD. Now the system will build an appropriate hierarchy which can be viewed under Access Governance Core > Manage > Groups.

So what can we do now?

Well... let's assume we want everyone in the United Kingdom to be assigned a role. Create and publish role called "United Kingdom Users". Now configure the role by updating the Org Units it is assigned to (ignoring the fact it is called Org Units which will no doubt be resolved in a future fix pack!). Add an "Org Unit" of type Location Hierarchy, navigate down through the hierarchy and find United Kingdom, click on OK and complete the following:

Default: Yes, and align users
Visibility Violation: No
Enabled: Yes
Hierarchy: Checked

That's it... every user under the United Kingdom hierarchy will automatically be assigned the United Kingdom Users role.

Property Changes In TDI - On The Fly

Wednesday, 23 March 2016
This week, I was asked if it was possible to update a TDI property while the TDI server was still running and, if so, how to go about doing it.

The reason for wanting to do so was akin to injecting a property into TDI at run-time so that it would "safely" shutdown an Assembly Line at a sensible point of processing. Now, there are many ways to address this actual requirement, but the fundamental question of how to inject a property into TDI is certainly something that can be explained easily.

tdisrvctl
The tdisrvctl command is a terrific command for communicating with a running TDI server. In order to communicate with the TDI server, you merely need to supply some key information, such as the Port Number that the TDI Server API is listening on, and some means to identify yourself using the TDI keystores. Finally, you supply an "operation" for the TDI Server to perform. Manipulating properties can be performed with the "prop" operation. In summary, tdisrvctl needs the following parameters:

  • -p {port}
  • -K {keystore}
  • -P {keystore password}
  • -T {trust store}
  • -W {trust store password}
  • -op prop


I set up a Project in TDI called propertyhandling, with an assemblyline called propertyhandling and a property in the propertyhandling properties file called status with a value of run.

In my AL, I created a conditional WHILE loop with this code:

if (system.getExternalProperty("status") == "run") {
      return true;
} else {
      return false;
}

I ran the AL and it trundles along nicely doing nothing but looping and consuming all available CPU. You got to love never-ending loops!

I then ran this command:

tdisrvctl.bat -p 1091 -T C:\TDISOL\testserver.jks -W server -K C:\TDISOL\serverapi\testadmin.jks -P administrator -op prop -c propertyhandling -o propertyhandling -g all

The -c, -o and -g options after the prop operation need a little explaining:

  • -c this is the Solution Name for my configuration, in this case propertyhandling
  • -o this is the name of the properties collection, in this case propertyhandling
  • -g this tells the TDI Server to return the property value for the property named, in this case all means return the values for all the properties in the properties file


When I run the command, the result I get on-screen is this:

--- propertyhandling ---

status=run

This is excellent news, I'm able to query the current properties held in this particular properties file. Swapping that -g argument for a -s argument means I can now manipulate the status property as such:

tdisrvctl.bat -p 1091 -T C:\TDISOL\testserver.jks -W server -K C:\TDISOL\serverapi\testadmin.jks -P administrator -op prop -c propertyhandling -o propertyhandling -s status=stop

The -s require a property/value pair to be supplied. In this case, -s is telling the TDI Server to set the value of property status to stop. When I run this command, I get this result:

CTGDJB070I The property status has been set and committed.

That looks positive and when I check whether my assemblyline is still running, I find that it has indeed come to an end - as expected. Thanks goodness, says my CPU!

Of course, there are a myriad of use cases for injecting properties at run time... safe shut-down of an assemblyline is just one.

TDI and HTTP POST

Tuesday, 26 May 2015
I was recently asked how to successfully perform an HTTP POST request using TDI's HTTP Client Connector. NULL values kept being processed by the web server and there seemed to be no obviously documented way to perform the task.

On the face of it, this seems like a straightforward piece of functionality, but the truth is that it is not quite as straightforward as it seems.

To understand how to pass parameters to a web server via HTTP POST using TDI, it would help to understand what is actually happening when using a standard web form.

Consider the following:

<html>
<head />
<body>
<form action="result.php" method="post">
User Name<br />
<input type="text" name="uname">
<br />
Password<br />
<input type="password" name="pass">
<br />
<input type="submit" value="submit">
</form>
</body>
</html>

The submit button on this form will cause the browser to send an HTTP request to the web server with a CONTENT-TYPE of: "application/x-www-form-urlencoded". This is the key to unlocking our problem!

The values for the attributes requested in the form will be passed in the BODY of the request rather like the query string you might see in HTTP GET requests:

uname=x&pass=y

So to mimic form submission using the POST method via TDI, all you need to do is follow these steps:

  • Set the Mode to CallReply (if you want to see what the web server has done with your request)
  • Set the Request method to POST
  • Set the http.Content-Type to "application/x-www-form-urlencoded"
  • Set the http.body to name/value pairs in query string format

Hopefully that will see your TDI Assembly Lines behaving themselves when acting as HTTP Client and attempting to use the POST method to transfer information.
