privacyIDEA 2.20.1 Enterprise Edition released

Today we released the stable version 2.20.1 of the privacyIDEA Enterprise Edition.

The Enterprise Edition as version 2.X.1 is released a few weeks after the corresponding major public release and contains necessary bug fixes. We already wrote about version 2.20.

Version 2.20.1 now fixes some minor bugs:

  • When using PostgreSQL database the administrator can now filter for the data as expected.
  • During enrollment the default realm will be set as default in the UI.
  • Errors with PassOnNoUser and PassOnNoToken were fixed.
  • The genkey parameter during enrollment was consolidated.

The Enterprise Edition of the Multi-Factor-Authentication system privacyIDEA is ment for enterprises and organizations, which need a reliable update process. It is available for Ubuntu 14.04LTS, Ubuntu 16.04LTS, CentOS7, RHEL7 and the Univention Corporate Server.

Federated authentication with privacyIDEA 2.20

Today we released privacyIDEA 2.20. Packages are publically available in the Laundpad repositories for Ubuntu 14.04LTS and 16.04LTS. You can also install the new version via the Python Package Index on any other distribution.

New Features in privacyIDEA

Federation-Handler

The new federation handler allows to forward authentication requests to sibling privacyIDEA instances.

This way you can setup network structures, where brances of an enterprise or sub organizations can run their own privacyIDEA instance under their own control. Authentication requests will be handled by a central privacyIDEA instance and forwarded to the corresponding instance, where the user and the user’s tokens are managed.

This way business devisions, departments or sub contractors can manage the tokens of their own employees.

The federation handler also offers new possibilities and business models for service providers.

New token type OCRA and DisplayTAN

In version 2.20 we also added the basic token type OCRA and the special type DisplayTAN. The DisplayTAN is a hardware card, which can communitcate with a smartphone via Bluetooth LE. This way the OCRA challenge is sent to the card, the user can check the challenge data and the card will generate an OTP value as response.

OCRA is specified in RFC 6287. A common use case is signing bank transactions. This way a TAN (OTP value) can be generated in hardware, and this TAN totally depends on the transaction information. Thus privacyIDEA can be perfectly used to manage authentication and signing devices for banking scenarios. We already talked about this in a previous blog post.

Login with different login names

The LDAP resolver now allows that a user can login with different LDAP attributes. The administrator can specify the list of attributes, which may be used as login names. This way an user can choose if he will login with the sAMAccountNAme, the email address or a telephone number.

Authentication cache

The administrator can now define if and how long succesful authentication should be cached. This way it is possible for a certain amount of time to authenticate with the very same OTP value again. Yes, this is not the original idea of OTP. But certain specific applications may need such a functionality. This behaviour is specified in an authentication policy, which can also depend on time and client IP.

More functions

Many policies now allow to use resolvers in the policy definition. This way the administrator can define the behaviour of privacyIDEA depending on user groups in detail.

During the rollout process of smartphone tokens, privacyIDEA display a QR-Code to the user. If the user is in doubt, that the QR-Code may be also seen by an attacker, he can now immediately regenerate the QR-Code.

All event handler definitions can now be ordered to your needs. This way the administrator can precisely define the behaviour and reaction of privacyIDEA.

The conditions of event handlers may now contain times and time deltas.

Challenge Response tokens can now be used to unlock the UI.

While installing Ubuntu packages, a PGP key pair is generated. The public PGP key can be easily used to encrypt the seed files before importing tokens.

You can find a complete changelog at Github.

Welcome dialog and privacyIDEA subscription

privacyIDEA is enterprise software. Managing lots of authentication devices for lots of users is a task that occurs in a company network.

privacyIDEA is licensed under an Open Source license. This guarantees, that a company using the Open Source software privacyIDEA can use this software for life. In contrast prorpietary software or software-as-a-service (SaaS) can be changed, billed differently or even completely deleted. You could not do anything about it. The Open Source privacyIDEA is under your control – forever.

The Open Source license dos not mean that a company has no costs in regards to two factor authentication. At least they need to pay the administrator.

In any case the Open Source license states that this software comes without any warranty. A company using privacyIDEA needs to be aware of this.

privacyIDEA is Open Source and thus comes without any warranty by default.

Due to this we decided to add a welcome dialog in version 2.20. This welcome dialog points out the fact, that it is important to get a Service Level Agreement (privacyIDEA Enterprise Edition) when running this software in an enterprise environment.

The administrator can define a policy (scope=webui, action=hide_welcome) which deactivates this welcome dialog. Anyway, if you run privacyIDEA with more than 50 assigned tokens and without subscription/SLA, we think it is a good idea, to warn the administrator again about the intrinsic risk running a software without warranty. The welcome dialog will be displayed again.

Using this approach we hope to help companies understand the legal situation when running privacyIDEA.

You are welcome to contact us with any questions.

World Wide Web Consortium is enrolling 2FA using privacyIDEA

Kassel, September, 26th 2017. The World Wide Web Consortium (W3C) is implementing privacyIDEA for securing access to their infrastructure with a second factor. The privacyIDEA Authentication System was chosen due to its flexible nature and the possibility to allow a single sign on experience for the users.

The services and especially the users are distributed world wide. Shipping authentication devices centrally is not efficient. Allowing only one type of authentication object is not an option. For W3C this is a big advantage that privacyIDEA can manage many different token type of different vendors at the same time. The lean REST API allows easy integration into their own user portal. W3C connected privacyIDEA to their existing user management. Users will be able to choose if they want to self-enroll Smartphone-Applications or U2F devices. Depending on the device type users gain access to resources of different security levels.

“Working with NetKnights is very effective. They provide just the right amount of consultancy for us to be able to implement the open source software privacyIDEA into our network and in our workflows.” said Ted Guild, Head of W3C Systems. Cornelius Kölbel, CEO at NetKnights, added: “W3C stands for Web standards. So we are very happy that W3C chose privacyIDEA, as this is an open solution, which complies to an open development workflow and open standards.”

About the World Wide Web Consortium (W3C)

The mission of the World Wide Web Consortium (W3C) is to lead the Web to its full potential by creating technical standards and guidelines to ensure that the Web remains open, accessible, and interoperable for everyone around the globe. W3C standards HTML5 and CSS are the foundational technologies upon which all Web sites are built. For its work to make online videos more accessible with captions and subtitles, W3C received a 2016 Emmy Award.

W3C’s vision for “One Web” brings together thousands of dedicated technologists representing more than 400 member organizations and dozens of industry sectors. Organizationally, W3C is jointly run by the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) in the United States, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France, Keio University in Japan and Beihang University in China.

Securing bank transactions with privacyIDEA

Making wiring money secure is a big challenge. We are all grateful, that we no longer need to go to the bank institute for wiring money to another bank account. It is also great that we do not need to use these TAN lists anymore, when we were asked to cross out number by number after each bank transaction.

But what are still the challenges with electronic bank transactions?

Integrity of the transaction data

The banking user uses a web interface to tell the bank, how much money he wishes to send to another account. A malware in the user’s browser, can change this data. Originially the user wanted to send €100 to the account 1234567890, but when he clicked the button “send”, the malware changed the transaction data to €10000 and to the account 666.666.XX. The bank receives the 10000 Euros for the evil account. It has no chance to know, that originally the user wanted to send 100 Euros to his friend. Also the user does not immediately know what happened.

The money might be gone.

TAN lists and OTP tokens

The transaction data could be changed before they reach the bank.

Several years ago TAN lists were used. Some banks are using OTP tokens, to identify the user, during a transaction. But the TAN lists and the OTP tokens can not ensure the integrity of the transaction data. The OTP token can be used to verify that it is really the true user, who is in the possession of the token and who triggered the transaction. But still a man in the middle can intercept a valid transaction and change the amount and account! Still neither the bank nor the user know, that something happened in between.

This is due to the problem, that there is no cryptographic link between the transaction data and the OTP.

OCRA: Linking transation and TAN

The OATH Challenge Response Algorithm (OCRA) can provide this missing link. OCRA is specified in RFC 6287. 

Just like HOTP and TOTP – which you might know from the Google Authenticator – the OCRA algorithm is defined by the Initiative for Open Authentication. Basically OCRA is some kind of enhanced HOTP algorithm.

The HOTP algorithm takes only one parameter, the “counter”, which is increased continously by each key press. In conjunction with the secret key a 6 or 8 digit one time password is calculated. The secret key represents the possession factor. Thus the one time password depends on the secret key and the parameter “counter”. In case you like buzz words like HMAC and SHA, take a look at RFC4226).

To cut a long story short, OCRA simply enhances the “counter” and allows many more input parameters for roughly the same algorithm. I.e. you can also put the account number and the amount into the OCRA algorithm. This will result in a one time password, which depends on the secret key and the complete transaction data. If you or an attacker would put other transaction data (input parameters) into the algorithm, this would result in another OTP value.

How can this be used for online banking?

The bank initially hands over the secret key to the user. The key can be contained in a hardware device or in a smartphone app. The bank knows each secret key of each user.

The user enters his transaction data on the banking website. The user also transfers the transaction data to his device (which contains the secret key). This transfer could be done manually or in any automatic manner using QR codes, network or bluetooth.

On the device the user verifies the correctness of the transaction data. Only then he continues by generating the TAN on the device. He now can add this TAN in the banking website. The transaction data and the TAN is sent to the bank.

As mentioned earlier the TAN cryptographically depends on the transaction data. The bank can use the user’s secret key to also calculate the TAN for the given transaction data. If the bank gets the same TAN, the bank knows, that the user really was willing to perform this transaction and that the transaction data were not modified by an attacker. Otherwise the modified transaction data would result in a different TAN.

In this scenario each and every transaction which is issued by a bank customer is cryptographically secure. So it is more important to protect the secret key in the device than the online banking account itself, since there can be no transaction without the secret key.

privacyIDEA, OCRA and DisplayTAN

privacyIDEA supports OCRA (the TiQR token) for quite a while. In the upcoming version 2.20 the OCRA mechanism was enhanced, so that it can be used with many different devices, especially with the DisplayTAN-card.

Banks do not need to program the key management for their web application on their own to support OCRA. They can easily use one single REST API call with privacyIDEA to add strong transaction security with privacyIDEA.

The DisplayTAN cards are attractive for customers, since they can be integrated in the banking card itself. This way the customer can have on card for all tasks.

privacyIDEA Enterprise Edition and Appliance

The privacyIDEA Enterprise Edition comes with new services and its own Enterprise-Repository. This Repository will contain Enterprise-Packages. These software packages will be released shortly after the main feature release as a kind of stable bug fixing release. E.g. after the main release 2.19 an additional enterprise version 2.19.1 will be released.

The Enterprise-Repository will only contain version 2.19.1, not the version 2.19. This way all software that can be installed from the Enterprise-Repository are stable enterprise releases. The customer can easily upgrade fom one enterprise release to the next enterprise release.

In addition the Enterprise-Repository also contains the new privacyIDEA appliance. We already blogged about it.

The Enterprise-Repository is available for Ubuntu 16.04LTS.

Howto use the Enterprise Repository

You need to create a file /etc/apt/sources.list.d/privacyidea-enterprise.list with the following contents:

deb https://yourname:yourpassword@lancelot.netknights.it/apt/stable xenial main

You as a customer will get your own credentials from NetKnights. Replace yourname and yourpassword with these credentials.

The software packages are signed. To verify the signature you need the public key:

wget https://lancelot.netknights.it/NetKnights-Release.asc

Verify the fingerprint (0940 4ABB EDB3 586D EDE4 AD22 00F7 0D62 AE25 0082) of the public key:

gpg --with-fingerprint NetKnights-Release.asc

Add the key to the keyring:

apt-key add NetKnights-Release.asc

Now you can update the package list and install the privacyIDEA Appliance:

apt update
apt install pi-appliance

Using the tool pi-manage you can create the first admin for the WebUI, create RADIUS clients and setup MySQL Master-Master-Replication.

Get your enterprise edition and your appliance!

 

Enhanced services for privacyIDEA Enterprise Edition

The Open Source Multi Factor Authentication system privacyIDEA is used by many users. NetKnights provides consultancy and support in different kind of subscription levels. Customers now receive more services with the privacyIDEA Enterprise Edition. These will be available by end of June.

Additional, stable packages

With every release the privacyIDEA project releases installation packages for Ubuntu 14.04 LTS and 16.04 LTS on the Ubuntu Launchpad repository. NetKnights’ Support customers will get additional access to an enterprise repository. Those packages will be available a few weeks after the release of the project packages. The enterprise packages contain bug fixes of possible bugs that might have occurred after the official release. The enterprise repository allows customers to easily update to newer versions. Thus support customers have an easy possibility to automatically update to the latest stable version.

The enterprise packages will be available for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and CentOS 7.

Applicance functionalities

Within the enterprise repository customers will also find a tool, that provides several appliance functionalities. This way the administrator does not need to type in any commands to the command line interface and does not need edit any configuration files.

To allow for best robustness and avoid additional attack vectors, the appliance-tool goes without a web interface, a database and configuration file templates. This also allows still the experienced administrator to edit configuration files directly.

The appliance-tool helps the administrator with the usual configuration tasks…

The privacyIDEA appliance-tool covers the following topics:

  • Base configuration of the privacyIDEA service as used in the file pi.cfg,
  • manage administrative realms,
  • manage local token administrators,
  • configuring the RADIUS server and especially the RADIUS clients,
  • configuring the master master replication of the MySQL server,
  • automatic time based backups,
  • manual backups and restore,
  • automatic time based Audit log rotation.

…like configuring RADIUS clients

Using the privacyIDEA appliance-tool the administrator can quickly and reliably fullfil daily tasks.

…or define automatic time based backups.

What customers say

It’s not often that I find an open source package which is truly as well thought and polished as privacyIDEA.

John WhittenSenior Systems Administrator, Network Manager

Support from NetKnights is very good. I received actionable responses in reasonable turnaround times accompanied by code examples and patches when necessary.

privacyIDEA 2.19 – Performance, U2F and secure Smartphone Apps

Today we released privacyIDEA 2.19. Packages are available in the Launchpad-Repos for Ubuntu 14.04LTS and 16.04LTS. You can also install privacyIDEA on any Linux distribution using the python package index.

New Features in privacyIDEA

Authentication performance

privacyIDEA 2.19 is up to 72% faster!

In tests in the lab privacyIDEA 2.19 shows improved performance. Authentication requests are up to 72% faster than in the previous version. This is also due to a new generic user cache. This user cache stores the link between login name and user object in the local SQL database. Thus time consuming requests to the originial user store like LDAP servers or Active Directory get obsolete.

Filter U2F devices for the users

Using policies the administrator can define which type of U2F device the user is allowed to register. In further policies the administrator can also define, which U2F types the users can use to authenticate at certain applications. This way the usage of certain U2F devices can be denied in your company or certain devices from specific vendors can be required for login to sensitive systems.

Secure smartphone apps with privacyIDEA

The classical smartphone app enrollment comes with several problems, which privacyIDEA 2.19 can solve.

In a previous blog post we already pointed out the limitations of the usual smartphone enrollment with the Google Authenticator.  As a company or large organization you want to keep control over the enrollment processes of your users. Thus in version 2.19 of privacyIDEA a better rollout possibility was added. The smartphone and the privacyIDEA server do a mutual key generation. Both create a component, the secret key is generated from both components. This avoids easy copying of the QR-Codes.

Read more details in the privacyIDEA Blog.

More functions

Version 2.19 comes with further detail improvements like using the IP address or the browser user agent in the event handler framework. The date and timeformat was consolidated. Now the complete ISO date with timezone is saved to the database. This heavily eases working across timezones in international setups.

You may want to take a look at the complete Changelog.

Enterprise Edition and Consultancy

NetKnights provides consulting and support with the privacyIDEA Enterprise Edition. Using Open Source you optimize your total cost of ownership this way, that there are no external limitations which dictate how long or short your may use the software. Getting the privacyIDEA Enterprise Edition including an SLA you get the warranty and thus operating safety.
