Is your password putting you at risk?

One major cause of data breaches is the stolen password. Once hackers have an email address and password, a world of possibilities are open to them. The dangers are not just limited to the account they have access to. Their hacker’s next steps usually include not only selling the details to other criminals but also “credential stuffing”; taking the login details for one account and trying it on others. Imagine if your ISP account was hacked – your work email, online shopping and other accounts most people possess would be targeted.

Companies would do well to introduce Two Factor or Multi-Factor Authentication to protect their employee and customer digital identities. Put simply, this requires another authentication criteria to be satisfied before granting access to a site or account. Many large corporates are turning to 2FA to help derisk their customer’s exposure to a data theft. Sony Playstation, Apple, Instagram, and Gmail all offer this additional security measure.

Simply put Two Factor Authentication, requires two out of three regulatory-approved authentication variables such as:

  • Something you know (such an email password).
  • Something you have (the physical bank card or an authenticator token, which can be hardware or digital).
  • Something you are (biometrics like your finger print or iris pattern).

The majority of attacks come from remote connections and 2FA can make distance attacks much less of a threat because accessing passwords is not sufficient for access and it is unlikely that the attacker would also possess the physical device associated with the user account. Take the Dropbox account holder hack for example. Hackers are unlikely to take your credentials and use them successfully on a second website if they are asked to provide a unique one-off code. It’s just too much work for them unless the gains are incredibly high. Each additional authentication factor makes a system more secure. Because the factors are independent, compromise of one account should not lead to the breach of others.

If your employer has a significant online presence, I would urge them to explore the potentials gains of 2FA. Of course KeyIdentity offers multiple solutions here, but irrespective of vendor the key principle is passwords alone are insufficient to provide adequate safeguards in the face of threats are expanding in scope and volume. Authentication should be able to perform whether you are online or offline, and in way that minimises user disruption. One of my favorite examples is Blizzard, the company who create games such as World of War Craft and Diablo, have a free authenticator, and it seems to work very effectively.

To sum up, if you want to avoid data about yourself, your company or organization and your customers being accessed:

  • Make your password non predictable and use unique passwords for each and every application
  • Check the privacy settings on any social media accounts, and turn them on if you haven’t already
  • Don’t use real birthdays and other identifiable data unless you really need to. Receiving a “Happy Birthday” email from a loyalty card provider a few days early or late is preferable to sharing a major personal identifier.
  • Do not enter easy answers to password forgetten questions. Best case choose something as answer that has nothing to do with the question at all. An example: What is the name of your dog? Answer:”I love companies that makes it so easy to attackers to steal my identity”.
  • Explore the benefits for 2FA or MFA inside your organization and look for it when you sign up for a new online service or similar.

Lastly, stay alert to any news of data breaches and immediately change your password or create a new account if you believe you have been affected. Don’t forget to also consider where else you may have used the same password and personal details. Hackers are constantly trying to get the better of us, so don’t give them any extra chances to succeed.

 

Why biometric authentication isn’t a silver bullet

There has been a lot of noise in the press recently about the rising tide of biometric authentication. The concept has been around for longer than many might think. For example, facial recognition was tested at the Superbowl in 2001, though the results were not widely circulated.

A few pioneering companies (particularly banks) are rolling out biometric trials, such as Standard Chartered in Asia, with finerprint and later voice recognition. In Singapore in particular, two rivals have both piloted voice authentication, DBS for customers dialling their call centre and OCBC for transaction authentication.

It’s not surprising – think of all the positives; easy-to-use, unique to the user, hard to share, tied to the individual’s own physical attributes and frankly, „cool“, as there is a sense of this is how our identities should be verified in a digital age.

Nothing could be meet the „something you are“ requirement than your voice, fingerprint or retina, so how can there be any downsides?

No security solution is without its drawbacks, and in the face of the biometric bandwagon, awareness of the following challenges helps balanced decision-making with all of the facts to hand:

You can’t change a fingerprint or retina scan: whilst of course this is in one sense a strength, it’s also a weakness. If your fingerprint is stolen and then used elsewhere there could be major financial and other wider implications. Unlike refreshing a password, how do you create a new fingerprint? It’s not so easy.

Biometrics are hackable: yes, even your fingerprints are. Tsutomo Masumoto made a working model based on „gummy bear“ material, initially from a live fingerprint and later from a fingerprint left on a physical object.

Creepy vs cool: a recent retail study found signifcant dfferences aomgst consumers in how they viewed a store’s knowledge about them. Whilst some groups saw recognising them by name as they walked the floor as „cool“, others found the possession of certain information to be „creepy“. Not every user wants to share their physical details with a retail outlet for example.

Legalities: data security and privacy are seen as highly important in Germany, and whilst there are variations amongst countries in the way these topics are viewed, who holds biometric data, where they store it, how it is used, and which organisations they share this with have many political, ethical and legal implications, and given how new biometrics are, many legal precedents have not yet been established. Facial recognition is legal in many US states for example, yet in other parts of the world this may not be the case.

False positives: Imagine the accuracy of biometric readings is 98-99% – that’s pretty good, no? Not if you have 10,000 employees entering offices around the world or logging in each day. 98% accuracy means 200 colleagues will not be able to start work on time. Imagine an issue with a fingerprint sensor at an entry door to the building and the queue of impatient co-workers behind the unfortunate blocked user. How many security teams look forward to a mass resetting of entry systems?

Individual use vs high volume: whilst fingerprint recognition might work to access a personal smartphone, it may not be suitable for far higher volume authetication requirements. If hundreds of people are entering a building at the same time,

Don’t underestimate a hacker’s determination: with every new security technology announced, there is sure to be a group of hackers eagerly awaiting the challenge of overcoming it, biometric or not. Retina and facial recognition for example is already being tricked by hi-res photographs of the individual, 3D models and more. Phone calls can be recorded to capture voices, keyboard strokes recorded to learn the typing cadence, and so forth. Whilst this is a lot of work to crack each account, high net worth individuals or celebrities may be viewed as targets worth investing time in.

If you’d like to dive deeper into the topic, there is a great Wired article summarising the legal, technical and ethical complexity involved in biometric authentication.

In the meantime, review any authentication option with an open mind and keep asking the „What if?“ questions. Explore the volume of users, use cases and level of security required; not every solution matches every scenario.

 

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

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.

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
