I want to secure some wso2 endpoints using basic auth security so that whoever invokes needs a username and policy
How do i configure this policy in wso2 esb?Can i create the username/password in a vault and validate the auth against it?
wso2 security policy screen
This doenst give an option to give username/password.. I dont need any roles validation ;but just need a username/password.. I know how to enable the security policy in the esb dataservice/endpoint ;but please help me in configuring the policy
you can refer to the answer in [1] regarding the basic authentication. If you want to use a security policy to achieve your requirements, you can modify the security policy and avoid using the following in the policy file.
<sec:CarbonSecConfig xmlns:sec="http://www.wso2.org/products/carbon/security">
<sec:Authorization>
<sec:property name="org.wso2.carbon.security.allowedroles">admin,role1</sec:property>
</sec:Authorization>
</sec:CarbonSecConfig>

Modified Based on the comment
Ths document [1] and blog post [2] contain the steps that need to be followed to develop a security policy. The blog post explains on how to add WS-Policy type, Integrity. But for the basic OAuth, you can select UserNameToken as the basic scenario. After adding the policy as a registry resource you can point the policy file as follows at the end of the data service
<data>
...
<policy key="conf:security/ESE-DevOps_policy.xml"/>
<enableSec>true</enableSec>
</data>
In addition to using the security policy to secure the data service, you can expose the data service through an API. The data service can be configured to invoke only through local transport to avoid any security issues. Then the API can be secured with Basic Auth handler. The document [3] contains sample code and the steps in developing a handler.

Is there a way to grant admin access to a third party in AWS without manually creating IAM role etc, purely via OAuth flow or similar?
Context: making an app that simplifies AWS account management, and want to make the UX to "connect to my account" as simple as possible. Failed to find anything like that in AWS docs. Want the app to be able to provision and manage resources, run terraform etc.
Check this out: Identity Providers and Federation. You will still have to create pre-defined IAM roles to define what permission users will assume
Yes it's doable. You do need to create IAM roles, if you want to give your users access to everything just create an admin role with permissions of ':' on all resources.
Then you should set up some type of SAML server, active directory federation services comes with everything out of the box. You can look for some open source SAML servers.
Then you have to setup SAML federation between your user account and your SAML backend.
we trying to add structure for SSO using WSO2, In WSO2 we need to create general Roles and connect this roles with Service provider (Please note service provider doesn't has custom roles so connection will be on service provider level with WSO2 general roles) , in WSO2 we found way to mapping SP roles with WSO2 roles but that not help us, and ,the structure in image below :
Beleive you are saying that your SP application does not persist or maintain the roles, rather you want WSO2 server to do so.
And you want to control authorization based on the availability of these roles for an user.
In that case, WSO2 server has no value nor need to know of the permissions you've assigned to these roles. You just define all the roles you want in the WSO2 server. Then (given that you use Oauth) by using scopes (mapped against each or multiple roles) to define access levels, you can issue access tokens to the users with the relevant scopes (defines access levels) after checking for the roles assigned to them.
On the resource server, it can validate the scopes of the provided access token against the Identity Server and grant or deny resource availability.

Anybody could explain why the operation assume-role-with-saml needs some parameters that are already in the saml-assertion such as role-arn and principal-arn?
After some research I'm able to answer. I was asking why send the --role-arn parameter if it is already in the saml assertion. In fact the saml assertion can have more than one role so in the api request is necessary to identify which role should be assumed. I found the answer in this link
The Amazon documentation for assume-role-with-saml provides the information:
The --role-arnstring option identifies the role that the caller is assuming.
The --principal-arnstring option requires closer reading. Amazon says
The Amazon Resource Name (ARN) of the SAML provider in AWS IAM that describes the IdP.
The explanation for the latter is given a few paragraphs before:
Before your application can call assume-role-with-saml , you must configure your SAML identity provider (IdP) to issue the claims required by AWS.
The same page provides a link to Using Identity Providers, which explains the term:
Using identity providers, you can manage user identities outside of AWS, and you can give these external user identities permissions to use AWS resources in your account.
That is, you could associate an external user identity with a role using the --principal-arn option. The --role-arn option is not really optional, but a required parameter.
The saml-assertion (--saml-assertionstring) option) is additional "glue" which may be used to check permissions. Following the link in the description for this option to Configuring a Relying Party and Adding Claims, Amazon says
You also need to create appropriate claim rules in your IdP with AWS as a relying party. These rules map information about users and groups in your organization into appropriate SAML attributes. This lets you make sure that SAML authentication responses (assertions) from your IdP contain the necessary attributes that AWS uses in IAM policies to check permissions for federated users.
and in turn, that links to a page describing the assertions: Configure Assertions for the SAML Authentication Response
I'm using WSO2 Identity Server with XACML for authorization.
I have users with serveral roles in IS. The user must select one of them to enter the app. So I need to grant the user based only in one of all his roles.
I used port.getDecisionByAttributes(subject, resource, action, environment); of the EntitlementService for asking with SOAP WS to the policy defined in XACML. The subject is the username. But It grants because it uses all user's roles.
Example:
User: peter
Roles: rolegranted, rolenotgranted, otherrole
When peter enter the app and select rolenotgranted it should not access the resource.
When peter enter the app and select rolegranted it should access the resource.
How do I define de XACML policy? and which method of the EntitlementService should I use?
Thank you
Actually, you need to write role based XACML policies in the PDP. Entitlement service method that you are using is fine. You can send the username in the XACML request and verify the user's roles using user store (via PIP), I would like to suggest you to go through this blog. It explain how you can write a role based XACML policy in WSO2IS and use it property.
I finally had met the requirements passing the role in the subject arg of the getDecisionByAttributes method. WSO2 IS doesn't check if this subject exists, so I can pass anything here and test it in the policy rule.
Is it possible to turn off authentication so that users don't need to provide username/password retrieving XML schemas using the schema URL of the WSO2 GREG? It doesn't help configuring the role everyone to be able to list schemas.
I want to do this until I have configured LDAP integration. Now I have to create a temporary user which I distribute.
You can use "wso2.anonymous.role. Add that role to schema resource in resource browser.
"The "wso2.anonymous.role" is a special role that represents a user that has not logged into the WSO2 Governance Registry Management Console. Granting "Read" access to resources for this role would mean that you do not require authentication to access resources using the respective Permalinks. The "everyone" role is a special role that represents a user that has logged into the WSO2 Governance Registry Management Console
