#Security

Security in IT is the protection of computer systems from the theft and damage to their hardware, software or information, as well as from disruption or misdirection of the services they provide.

See the InterSystems Documentation on Security.

Hi,

I've added a REST service which worked fine on our test system but failed on the production environment because UnknownUser does not have %All set and I really don't want it set on production (in fact I've also switched it off on test).

Is there a way to allow a single REST service to have unauthorised access?

I was thinking adding a resource/role to UnknownUser specifically for that service but I've never touched on Users/Roles/Resources so I'm struggling to work out what needs adding where.

Thanks

Ensemble namespace permission

Hi,

I am attempting to set up a security role for our support team so they can have read access to the production and messages.

I have given the role RW rights on the resource associated with the database. However, when I log into Management Portal and select "Ensemble", the "Available Ensemble namespaces" list is empty.

What permissions do i need to set to be able to navigate to the production?

Thanks in advance,

Carl

Hi All,

Actually, I'm developing few restful API's. I want to create a authentication tokens and display it on my login restful API. If I'm using CSP sessionId, how can I validate the session Id's in another or continues restful API's. else, is there any other approach to handle this task.

My Primary goal is, I have to integrate 2 different front end applications. One is Zen framework another one is web pages from Python.

If any lead, it would be appreciated.

Thanks,

Arun Kumar Durairaj.

About regulations

Personal data privacy regulations have become an indispensable requirement for projects dealing with personal data. The compliance with these laws is based on 4 principles:

When you first start working with InterSystems IRIS, it’s a common practice to install a system with only a minimum level of security. You have to enter passwords fewer times and this makes it easier to work with development services and web applications when you're first getting acquainted. And, sometimes, minimal security is more convenient for deploying a developed project or solution.
And yet there comes a moment when you need to move your project out of development, into an Internet environment that’s very likely hostile, and it needs to be tested with the maximum security settings (that is, completely locked down) before being deployed to production. And that’s what we’ll discuss in this article.
For more complete coverage of DBMS security issues in InterSystems Caché, Ensemble, and IRIS, you may want to read my other article, Recommendations on installing the InterSystems Caché DBMS for a production environment.
The security system in InterSystems IRIS is based on the concept of applying different security settings for different categories: users, roles, services, resources, privileges, and applications.

Users can be assigned roles. Users and roles can have privileges on resources — databases, services, and applications — with varying read, write, and use rights. Users and roles can also have SQL privileges on the SQL tables located in databases.

Hi,

Has anyone tried to call Security.Users class (in %SYS namespace) for creating or editing users from a shell script (or any programming language)?

If yes, can you please share your code?

We are trying to automate some stuff and would like to know how this worked for others.

Thanks,

Bharath Nunepalli.

Using Oauth2 with SOAP (Web)Services

Hi guys,

Couple days ago, a customer approached me with the wish to enhance their existing legacy application, that uses SOAP (Web)Services so it shares the same authorization with their new application API based on REST. As their new application uses OAuth2, the challenge was clear; how to pass access token with SOAP request to the server.

After spending some time on Google, it turned out, that one of possible ways of doing so was adding an extra header element to the SOAP envelope and then making sure the WebService implementation does what is needed to validate the access token.

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

Cannot type password in Terminal

I just tried to log into our QA server and connect to Terminal (v 2013.1).

I can type in my username but when I attempt to type my password, no characters are typed. When I press ENTER the password is invalid.

I can connect to the management portal and the studio development environment without any problems. Also, I do not have this problem when connecting to the terminal in our production environment (2010).

Does anyone know what can cause this type of problem?

Thanks.

I am attempting to pragmatically create a bunch of roles and then assign the appropriate resources to that role.

Currently, the only ways to add resources to a role are to:

1. Do through Management Portal

2. Go through ^SECURITY (add resource one at a time)

My Intention would be to do the following: do ^SECURITY Role Setup Edit Role When prompted for resources to add, be able to use *

List All Available Resources

Maybe I haven't seen anything about it in the documentation, but why isn't there a way to list all the Resources from the %SYS namespace from a class rather than through ^SECURITY

Thinking maybe something like this:
##Class(Security.Resources).ListAll(.result)

SQL -99 error while viewing a listing

This error is sometimes seen while viewing a listing in InterSystems IRIS Business Intelligence:
ERROR #5540: SQLCODE: -99 Message: User <USERNAME> is not privileged for the operation (4)

As the error suggests, this is due to a permission error. To figure out which permissions are missing/needed, we can take a look at the SQL query that is generated. We will use a query from SAMPLES as an example.

debugging web client

I used the soap wizard to create a web client based on the wsdl. I was able to get a valid response back, and now it looks like the error is in decrypting the soap message response "inbound"

Hello,

I am working on Ensemble 2017.2.1 .
I need to export my security settings into an extern database, in order to make a report.

I've created a Business Operation with an SQL Adapter into a Namespace, but I don't know how to get every security data from "%SYS" Namespace ( SQLPrivileges , Resources , Roles , Services , Users ... ).

I dont't want to use the terminal and the ^SECURITY routine, because i don't want to store a XML file on the server.

Cache / Ensemble version 2016.2.2.853.0

I have a need to restrict ODBC access to certain users to prevent unwanted access to our cache database.

We have a limited number of legacy applications that use ODBC to connect to read data and are currently not in a position to have these amended any time soon so in the interim, I am hoping someone will be able to provide me with some assistance.

Any suggestions on where to start?

InterSystems Data Platforms products allow you to export and import security settings in two different ways.

This article talks about those options:
- On the command line, using ^SECURITY
- Programmatically, using the Export and Import methods of classes in the Security package

Exporting settings on the command line (^SECURITY)

You can export everything or individual sections of the security settings.

The .NET Core Identity model has an IPasswordHasher<> interface for for

  • Hashing a password so that it can be stored in a database
  • Verifying a provided plain-text password matches a previously stored hash.

I am getting invalid password errors during the login process when the .NET Core Identity model computes a hash from a plain text input and compares it to a password hash value I've returned from Caché. The default hashing algorithm is PBKDF2 with HMAC-SHA256, 128-bit salt, 256-bit subkey, and 10,000 iterations (detailed article on .NET Core Identity PasswordHasher). The algorithm Caché uses is probably different which may be why I am getting errors.

I would like to allow some departmental user to view the ensemble portal. I want to make sure they are not allowed to do any changes (like stop and start interfaces from portal)

I have created one userbut limited with SQL privilages. But using this account, the portal view is not accessible.

It would be appreciated if anyone can adice me on this. I know this may be a silly question.

Regards,

Anti CSRF Methods

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

Hello,

I have a very simple web service that I'd like to secure via SAML Authorization with X.509 Certificates. I am, however struggling with documentation and my lack of cryptographic skills. (I do this just for educational purposes now, but need to use it in the future)

Does anyone have an example that shows how to construct a SOAP Client with adding all necessary security headers manually or point me to a decent learning resource?

Thank you very much!
