FIDO U2F: what it is and how you can secure your web applications using LinOTP

This is the first part of a series of blog entries about FIDO U2F and how you can use FIDO U2F and LinOTP to secure your web applications.

Kicking off, we would like to introduce you to FIDO U2F and explain the idea behind it. Following blogs will be about the protocols and how you can use LinOTP to integrate FIDO U2F in your application.

What is FIDO U2F?

FIDO U2F is a technical specification defining a mechanism to reduce the reliance on passwords to authenticate users. It can be used to enrich a password-based authentication with a second factor or to replace the password-based login completely, depending on the use case.

FIDO U2F is developed by the FIDO Alliance (KeyIdentity is a member) and actively extended to new authentication models and markets. The driving idea behind FIDO U2F is to allow the user to bring their own token to their registration process and allow you to securely validate the identity of the user going forward and the user only having to use one token for all websites without compromising security.

USB, NFC and Bluetooth are now defined as transport protocols and a wide range of devices is available to make use of them. Your users can decide on the method and vendor they prefer, based on costs, design or availability. The FIDO U2F implementation on the side of the web application is the same for all tokens implementing the FIDO specifications.

FIDO U2F is based on public key cryptography. When the user registers at your site, a key pair specific to your site is generated in the FIDO U2F token and, depending on the device, is stored on the token. The public key is then registered in your LinOTP backend. When the user authenticates later on, a challenge is presented to the FIDO U2F token and proof of the possession of the private key is presented by signing the challenge. The FIDO protocols are designed to protect the user’s privacy. It is not possible to track a user across services even though the same token is used.

The handling of the device and the communication with the USB, NFS or Bluetooth transportation protocols is provided by the user’s browser and built-in or available as a plug-in. Currently only Google Chrome has built-in support, but support by Microsoft and plug-ins for Firefox are available.

FIDO U2F is still a pretty young standard, but adoption is picking up. After being developed mainly by Google and Yubico, the FIDO Alliance now has an impressive set of members and the range of specifications grew actively and in interesting areas over the last year.

This was just a quick introduction, in the following parts we will look at the registration and authentication process and how an implementation of FIDO U2F can look.

 

An open source core: the answer to cryptographic back doors?

What is a cryptographic back door?

“A backdoor is an intentional flaw in a cryptographic algorithm or implementation that allows an individual to bypass the security mechanisms the system was designed to enforce. A backdoor is a way for someone to get something out of the system that they otherwise would not be able to. If a security system is the wall, a backdoor is the secret tunnel underneath it.”
How the NSA (may have) put a backdoor in RSA’s cryptography: A technical primer, by Nick Sullivan, January 6th 2014

For any organisation concerned at the possibility of cryptographic backdoors being built into the authentication solution they invest into, open source software (OSS) can be seen as offering an alternative, for several reasons:

  • A closed-source system is easier to contain malicious elements, because OSS has a greater potential of any risk areas being discovered by the open source community.
  • Contrary to the perspective that releasing code benefits attackers because hostile audiences can see OSS code, attackers are able to reverse engineer binary (proprietary) code patches in minutes and generate exploits. Security by obscurity has never been a solid approach. Multiple academic papers demonstrate how easy it is, „in some of the cases they tried, they claimed to be able to create an exploit in minutes after receiving the patch and comparing the patched version of the application with the unpatched version.“ https://isc.sans.edu/forums/diary/The+Patch+Window+is+Gone+Automated+PatchBased+Exploit+Generation/4310/
  • OSS offers the IT security team the opportunity to audit the code and conduct proper due-diligence.
  • OSS gives the IT security team the possibility to even adjust the code to their own needs if possible. Customers can, but do not have to, take part in the development of the code.
  • If source-code is public-available, and a maintainer stops working on it for whichever reason, it still can be developed and maintained by anybody else.

For any organisation concerned at the possibility of cryptographic backdoors being built into the authentication solution they invest into, open source software (OSS) can be seen as offering an alternative, for several reasons. A closed-source system is easier to contain malicious elements, because OSS has a greater potential of any risk areas being discovered by the open source community.

While proprietary vendors have argued that their software is more secure because it is secret, this can be countered with the view that closed source is so easy to use that weak crypto or implementing a crypto back door by selecting fixed numbers as parameters can occur, whilst in OSS this is not possible.OSS offers the IT security team the opportunity to audit the code and conduct proper due-diligence and even adjust the code to their own needs if possible.

With Open Source at its core, LinOTP reduces the risks associated with proporietary software.

 

 

 

LSE announces a number of new product updates for multi-factor authentication

Germany-based LSE Leading Security Experts GmbH, a holding of MAX21 Management und Beteiligungen AG (stock market symbol: MA1, ISIN: DE000A0D88T9), will expand its family of adaptive multi-factor authentication products during the second quarter of 2016. Among other updates, an offline authentication facility will be gradually integrated into the product suite. Unlike conventional OTP tokens, this new approach enables strong authentication even without a direct connection to the LSE LinOTP server.

LSE LinOTP Offline Authentication

This cross-product feature will allow companies to provide mobile workers with a secure form of offline authentication. This is particularly relevant for employees who travel a lot, or who work abroad without a direct connection to the company’s network and thus the backend OTP server. “Previously, secure two-factor authentication methods with OTP were limited to devices with a permanent network connection. Now mobile devices such as notebook computers can also be protected with real and cryptographically valid multifactor authentication schemes,” says Sven Walther, Managing Director and CTO of LSE Leading Security Experts GmbH.

Unlike other solutions being marketed, the process developed by LSE does not require secret material to be stored on the system being authenticated. The feature will become available to customers during the second quarter of 2016 through update releases of LSE LinOTP, LSE LinOTP authentication providers, and the new LSE LinOTP multi-token app.

LSE LinOTP Multi-Token App: OATH compliant

The LSE LinOTP multi-token app is an integral component of the new LinOTP family of offline authentication products. In addition to the LSE LinOTP QR token, the multi-token app supports tokens for OATH TOTP and HOTP and is therefore compatible with all OATH-based systems (like Google, Dropbox, Github, and many others). Access to the app’s data is password-protected by default. Key data can be transmitted in conjunction with LinOTP in a separately protected secure roll-out process. Initially, this solution will be available for iOS and Android.

RPM packages for simplified installation of Red Hat-based systems

During the second quarter of 2016, LSE will provide its customers with LinOTP repositories containing RPM packages. This expands the support of packaged deployment to systems based on RHEL 7 and RHEL 6. The installation for Red Hat-based systems will be streamlined and allows faster deployment using various optimized configuration templates. The LSE LinOTP RPM packages for RHEL 6/7-based systems supplement the LSE range of packages for Debian “Jessie” 8, Ubuntu 12.04, and Ubuntu 14.04.

LSE LinOTP authentication provider for Microsoft Windows and OS X®

In the course of regular product updates, the family of LSE LinOTP authentication providers will expand to include the OS X® operating system in addition to the Microsoft Windows and Linux operating systems, and for the first time offer OS X® strong offline authentication with access to LSE LinOTP. The LSE LinOTP authentication provider for Microsoft Windows will be enhanced to allow a direct connection of the LinOTP API via encrypted channels based on HTTPS.

LSE introduces the new version of its multi-factor authentication and OTP solution: LinOTP 2.8.1 supports multiple languages and has improved features

LSE Leading Security Experts GmbH is introducing LinOTP 2.8.1, the latest version of its vendor independent solution for adaptive multi-factor and 2-factor authentication and OTP processes (OTP: one time passwords).

LSE is now offering its latest LinOTP version in Spanish, French, Italian, and simplified Chinese in addition to the previously available English and German. In addition to the expanded available languages, LinOTP 2.8.1 has new features for monitoring and improved capabilities for server migration and complex setups. The improved user filters and support for HSM (hardware security module) migrations are also new.

With the additional languages, LSE has consistently continued to internationalise the LinOTP product line. The larger selection of available languages applies to both the self-service user portal as well as the management interfaces. “We appreciate the opportunity to provide more users worldwide with multi-factor- or two-factor-authentication,” states Sven Walther, Managing Director and CTO of LSE Leading Security Experts GmbH.

New options for monitoring

LSE is introducing a new API for monitoring internal LinOTP processes with LinOTP 2.8.1. This provides, for example, information on the statistics and the status of the tokens, the status of the HSM (hardware security module) encoding, and the status of the UserIDResolver with configurable permissions.

Improved features for server migration and complex setups

Previous features for routing registration data to other authentication servers have been improved with options for generic routing. This means migration scenarios and complex setups with multiple LinOTP instances are easier to model and administer.

Improved user filters

Today’s enterprise environments require a differentiated approach to user policy management. LinOTP 2.8.1 adds options for managing the configurations and policies based on user groups, user attributes, and regular expressions. This considerably simplifies detailed and complex permission scenarios in the setup.

 

HSM migration

In the new version of LinOTP it is now possible to migrate an HSM or a corresponding HSM cluster. LinOTP 2.8.1 includes features and tools to migrate data between two HSMs and thus makes it easier to update the HSM hardware. LinOTP supports PKCS#11-based HSM systems such as the SafeNet Network HSM (previously Luna SA).

LSE LinOTP Smart Virtual Appliance (SVA) — Important Technical Information

LSE LinOTP Smart Virtual Appliance (SVA) -- Important Technical Information

Relevant to: Customers using the
LSE LinOTP Smart Virtual Appliance (SVA)
Affected SVA versions: 1.2 and below

If the preceding conditions apply to you, please read this message
very carefully. It contains important lifecycle information that could
impact your support and security situation.

Dear LinOTP customers,
dear partners,

in our technical newsletter of 8 September 2015 we informed you about
the availability of the LSE LinOTP Smart Virtual Appliance (SVA)
2.0. As described there, that version upgraded the technology of the
appliance. Its basic operating system was moved to the newest
generation (an advance of two major versions), and we have accordingly
recommended installing the upgrade. This requires a migration and
cannot be performed by means of the automated update facility, which
is why some (few) customers have not yet made the transition. The
migration of the configuration and token database is, however, fully
supported.

If you have not yet performed the migration, we now recommend that you
urgently migrate to the current version of the LinOTP Smart Virtual
Appliance (SVA). Since the Debian team will cease long-term support of
the Debian GNU/Linux version 6.0 ("squeeze"), we will in your own
interest discontinue support for SVA versions 1.2 and below, since the
security and stability of these versions can no longer be guaranteed.

*** Support and the availability of updates for the LSE LinOTP Smart
Virtual Appliance 1.2 ends on February 29th 2016. Therefore, SVA version
1.2 will be in its EOL (end-of-life) state effective March 1st 2016.
Support, patches, and updates will no longer be available, and
safe operation can no longer be guaranteed.

Only those few customers who have not migrated yet will need to do
this now. Users of SVA version 2.0 and later are expressly not
affected.

If you want to perform the migration, the appropriate instructions are
available in the online manual
(http://linotp.org/doc/latest/part-appliance/update_guide_appliance_1.2_to_2.0.html).
Should
you still use an LSE LinOTP SVA Installer in a version below 20,
please order a current installer from support@lsexperts.de.

Our support team will gladly be available for questions or migration

Thank you for using LSE LinOTP in your environment.

Sincerely,

Your LSE LinOTP Team

Open Source: LSE presents Authentication Platform LinOTP 2.8 with FIDO U2F Token

Open Source: LSE presents Authentication Platform LinOTP 2.8 with FIDO U2F Token

Innovations of the OATH-certified version LinOTP 2.8 include features such as FIDO U2F support, registration of FIDO U2F, preparing email and SMS tokens in a self-service portal, temporary email and SMS tokens, multiple challenge response tokens per user with identical token PINs and optimized troubleshooting. “With LinOTP 2.8 we are offering companies, which want to provide their staff with secure logins via multi-factor authentication (MFA/2FA), a technically sophisticated, manufacturer-independent and extremely adaptive solution“, explains Sven Walther, Managing Director and CTO of LSE Leading Security Experts GmbH.

Master Key Token “FIDO U2F“

With full support of the U2F protocol of the FIDO Alliance, various logins can be executed securely using one and the same token. This means it is possible to use the user-friendly U2F tokens of various manufacturers as a second factor for authentication. As a result, new scenarios in the field of “Bring Your Own Token“ will in future become reality. The open standard FIDO U2F is especially interesting for large companies on account of its transparency and independence. LSE Leading Security Experts is a member of the FIDO Alliance. Further information on FIDO U2F available at www.fidoalliance.org.

Additional New Features

To facilitate roll-out of the token, users can now also prepare FIDO U2F, email and SMS tokens themselves in the self-service portal of LinOTP, in addition to token types available up to now. All token types available there can be configured via policies from the LinOTP administrator. If a token is lost, a temporary email or SMS token can also be set up in LinOTP 2.8 instead of a temporary password. Another new feature involves the simultaneous setting up of several challenge response tokens per user with identical token PINs.

Availability

LinOTP 2.8 is available now from the repositories of LSE at www.linotp.org as a Debian package. Updated package are available for Ubuntu in LinOTP PPA on Launchpad. LinOTP 2.8 is also available via the Python package index (PyPI). Users of LSE LinOTP Smart Virtual Appliance can obtain LinOTP 2.8 via the integrated update administration.

LSE LinOTP Hotfix and Security Advisory

Die LSE Leading Security Experts GmbH empfiehlt, nachstehendes Hotfix
für den sicheren Betrieb von LinOTP einzuspielen. Diese Empfehlung gilt,
wenn Sie nicht die automatischen Updatemechanismen zur Aktualisierung
von LinOTP verwenden (siehe unten, unter “LSE LinOTP Smart Virtual Appliance”).
Im Falle der Verwendung der automatischen Updatemechanismen besteht kein
Handlungsbedarf, da LinOTP dann bereits auf dem neusten Stand ist.

Der Hotfix schließt eine kritische Lücke und verhindert damit, dass
diese potenziell ausgenutzt werden kann.

Die Lücke würde einem unauthorisierten Benutzer potenziell das Übermitteln
von ungewollten Zeichenfolgen ermöglichen, welche dann im
LinOTP-Log, d.h. der LinOTP-Log-Datenbank, gespeichert werden.
Zu einem späteren Zeitpunkt könnte dann, unter bestimmten Umständen, diese
Zeichenfolge im Admin-Kontext, also durch einen Administrator bei der Verwaltung
von LinOTP, versehentlich zur Ausführung gebracht werden. Damit könnte möglicherweise
Schadcode eingeschleust werden. Dies wird verursacht durch unzureichende
Aufbereitung des Outputs, bedingt durch ein von LinOTP verwendetes Widget.

Wir haben für unser Produkt LinOTP ein diesbezügliches Advisory veröffentlicht,
welchem bei Interesse die entsprechenden Details entnommen werden können.
Wir danken ausdrücklich Tomas Rzepka für seine diesbezügliche Mithilfe
und den wertvollen Beitrag.

Nach unserem Kenntnisstand wurde diese Lücke bisher nicht aktiv ausgenutzt.

Wir stellen unseren Kunden den Hotfix in verschiedenen Formaten und Versionen
zur Verfügung. Die Pakete enthalten über den Hotfix hinaus keine weiteren Änderungen.
Wir empfehlen, den Hotfix umgehend einzuspielen.

Bitte verwenden Sie die unten aufgeführten Installationswege.

In kommenden Versionen von LinOTP (2.8 und höher) werden weitere Verbesserungen
enthalten sein, um den potenziell möglichen Angriffsweg bereits von vornherein
aus der LinOTP API heraus zu verhindern. Durch Sanitisierung der Antworten innerhalb
unserer JSON-basierten API, wird HTML-Output zusätzlich bereinigt und damit abgesichert.

 

Installation des Hotfix

Wir bieten für verschiedene LinOTP Versionen Pakete zum Update an.

2.6.1.1 –> 2.6.1.2
2.7.0.2 –> 2.7.0.3
2.7.1.2 –> 2.7.1.3
2.7.2.1 –> 2.7.2.2

Wir bieten Ihnen eine Installationsanleitung mit Links zum Download.

Sollten Sie eine ältere Version von LinOTP (<2.6) verwenden oder den Hotfix
unabhängig vom Paketmanagement einspielen wollen, stellen wir auch die auszutauschende
Datei mit einer Installationsanleitung zur Verfügung.

Sollten Sie Fragen zur Anwendung des Hotfix haben, helfen wir Ihnen gerne weiter:
