Organizations are deploying distributed, hybrid architectures that can span multiple security domains. At any moment, a user could be accessing the corporate data center, the organization’s cloud infrastructure, or even a third party, #SaaS web application. #SAML can provide the identity information necessary to implement an enterprise-wide single sign-on solution.
Proving or asserting one’s identity in the physical world is often as simple as showing a driver’s license or state ID card. As long as the photo matches the face, that’s typically all that is needed to verify identity. This substantiation of identity is a physical form of authentication, and depending on the situation, the individual is then authorized either to receive something or to do something, for instance, enter a bar, complete a purchase, etc.
In the digital world, identity verification is not as easy as showing the computer monitor a driver’s license. To gain entry, you must provide information like a name, password, randomly generated token number—something you have, something you know, or something you are—to prove you are who you say you are.
Gaining access to corporate assets is no different. Many organizations have multiple different resource portals, however, each requiring digital proof of identity. Their users may also need to access partner portals, cloud based Software as a Service (SaaS) applications, or distributed, hybrid infrastructures that span multiple data centers, each requiring a unique user name and password. In addition, the average employee must maintain about 15 different passwords for both her private and corporate identities, with many of those passwords also being used for social media and other risky entities. Statistics show that 35 to 50 percent of help desk calls are related to password problems, with each call costing a company between $25 and $50 per request.
Security Assertion Markup Language (SAML) is an XML-based standard that allows secure web domains to exchange user authentication and authorization data. It directly addresses the problem of how to provide the users of web browsers with single sign-on (SSO) convenience. With SAML, an online service provider can contact a separate online identity provider to authenticate users who are attempting to access secure content. For example, a user might need to log in to Salesforce.com, but Salesforce (the service provider) has no mechanism to validate the user. Salesforce would then send a request to an identity provider, such as F5 BIG-IP Access Policy Manager (APM), to validate the requesting user’s identity. BIG-IP APM version 11.3 supports SAML federation, acting as either a service provider or an identity provider, enhancing the employee’s online experience and potentially reducing password-related tickets at the help desk.
BIG-IP APM version 11.3 can act as either a SAML service provider or a SAML identity provider, enabling both federation and SSO within an enterprise.
BIG-IP APM as a Service Provider
When a user initiates a request from a SAML IdP and the resources, such as an internal SharePoint site, are protected by BIG-IP APM, BIG-IP APM consumes that SAML assertion (claim) and validates its trustworthiness. This ultimately allows the user access to the resource. If the user goes directly to BIG-IP APM (as an SP) to access a resource (like SharePoint), then the user will be directed to the IdP to authenticate and get an assertion. Once a user is authenticated with a SAML IdP and accesses a resource behind BIG-IP APM, he or she will not need to authenticate again.
BIG-IP APM as an Identity Provider
Provided there is an SP that accepts assertions, a user can authenticate with BIG-IP APM to create an assertion. BIG-IP APM authenticates the user and displays resources. When the user clicks on an application, BIG-IP APM generates an assertion. That assertion can be passed on to the SP, which allows access to the resource without further authentication. When the user visits the SP first, the process is SP initiated; when the user goes directly to the IdP (in this case, BIG-IP APM) first to authenticate, the process is IdP initiated.
BIG-IP APM in a SAML Federation
SAML can be used to federate autonomous BIG-IP APM systems. This allows a user to connect to one BIG-IP device, authenticate, and transparently move to other participating BIG-IPs devices. Session replication is not part of SAML, but administrators can populate session information on participating systems. This means that BIG-IP device federation does not enable the use of a single session within the federation; it only enables information exchange among multiple members of the federation. Each participating BIG-IP device maintains its own independent session with the client, and each has its own access policy that executes separately and independently.
Participating federation members can exchange information with any other federation members outside of sessions where needed. A common configuration is to have a dedicated BIG-IP device as a primary member to which users are authenticated and that provides information to other members. This allows a number of other BIG-IP devices to work in conjunction with that primary member. The primary member is dedicated as an IdP, while the other participating members operate as SPs
The benefits of deploying BIG-IP APM as a SAML solution certainly include better password management, fewer help desk calls, and an improved user experience, but BIG-IP APM can also add additional context to requests. For instance, it can include endpoint inspection results as attributes to inform the application of the client’s security posture. In addition, IT administrators do not need to retrofit applications (e.g., .NET apps do not need a Kerberos claims plug-in). Another advantage is extensive session variable support, which allows organizations to
customize each user session. BIG-IP APM can bring SAML to resources and applications with minimal back-end changes—or none. These benefits all complement the values of BIG-IP APM to the overall traffic management of an organization’s IT infrastructure.
IT infrastructure has changed dramatically over the past few years, with many applications moving to cloud-based services. Corporate employees have also morphed into a mobile workforce that requires secure access to that infrastructure any time, from anywhere, and with any device. Bridging the identity gap between physically and logically separated services allows organizations to stay agile in this ever-changing environment and gives users the secure access they need around the clock.
BIG-IP APM version 11.3, in addition to delivering high availability and protecting organizations’ critical assets, provides a SAML 2.0 solution that offers the identity bridge needed to manage access across systems.

Container technology is sending shock waves through the world of cloud computing. Heralded as the 'next big thing,' containers provide software owners a consistent way to package their software and dependencies while infrastructure operators benefit from a standard way to deploy and run them. Containers present new challenges for tracking usage due to their dynamic nature. They can also be deployed to bare metal, virtual machines and various cloud platforms. How do software owners track the usag...

Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...

Malicious agents are moving faster than the speed of business. Even more worrisome, most companies are relying on legacy approaches to security that are no longer capable of meeting current threats. In the modern cloud, threat diversity is rapidly expanding, necessitating more sophisticated security protocols than those used in the past or in desktop environments. Yet companies are falling for cloud security myths that were truths at one time but have evolved out of existence.

Public Cloud IaaS started its life in the developer and startup communities and has grown rapidly to a $20B+ industry, but it still pales in comparison to how much is spent worldwide on IT: $3.6 trillion. In fact, there are 8.6 million data centers worldwide, the reality is many small and medium sized business have server closets and colocation footprints filled with servers and storage gear. While on-premise environment virtualization may have peaked at 75%, the Public Cloud has lagged in adop...
