Many organizations use Office 365’s cloud-based mail, collaboration and communication services as the dominant workload. However, as services move to the cloud, data centers are no longer local, and end-user experience can suffer. A congested Internet connection will mean sluggish application delivery that puts a damper on user productivity and ultimately threatens application usage. Learn how to address these performance issues.

Patching is a key strategy for managing vulnerabilities and ensuring enterprise-wide security. Unfortunately, there are often so many flaws in software that patching becomes an overwhelming process. This white paper describes an approach to patch management that allows you to prioritize vulnerabilities that pose the greatest risk and accelerate the speed at which patches are applied. Also inside, find ten steps to improve patching – read on to learn more.

Organizations today are reevaluating their security strategies as they move their data and applications to the cloud. This whitepaper by Bloor Research discusses the challenges of security in the cloud and how the use of cloud-based services will enable organizations of all sizes, from the very smallest to multinational enterprises, to put trust back into the security equation.

Organizations have traditionally viewed vulnerability scanners as a tactical product, largely commoditized and only providing value around audit time. But with limited resources and a real need to reduce risk, organizations need the ability to pull in threat-related data, combine it with an understanding of what is vulnerable, and figure out what is at risk. This report from Securosis outlines how yesterday's vulnerability scanners are evolving to meet this need, emerging as a much more strategic component of an organization's control set than in the past. Learn how vulnerability scanners are evolving to provide real value beyond vulnerability reports for auditors - emerging as a strategic component helping organizations effectively lower risks.

A zero-day threat is a vulnerability that becomes known to the vendor on the same day it becomes known to the public, meaning IT assets targeted by a zero-day threat won't have a patch available when it's needed. However, zero-day attacks operate in a realm of the probable - they work only because there are exploitable vulnerabilities within IT systems. Many of these can, and should be prevented. This guide describes why organizations are vulnerable to zero-day attacks, and what you can do to add a zero-day offense to your existing vulnerability management processes to protect your organization's assets and data.

Distributed denial-of-service attacks may be organized by type into a taxonomy that includes network attacks (layers 3 and 4), session attacks (layers 5 and 6), application attacks (layer 7), and business logic attacks. Each type may be matched with the best F5 technology for mitigating that attack. This paper explains how taken together, the F5 BIG-IP portfolio of products provides effective anti-attack technology for each layer of the taxonomy and can also defend against specific attack tools, network reconnaissance, and low-bandwidth asymmetric attacks.

This white paper examines the DDoS threat spectrum including conventional network attacks, HTTP and SSL floods, and an emerging wave of low-bandwidth threats, plus the new threat vectors likely to target emerging service platforms.

This whitepaper utilizes end-user interviews to better understand their DDoS defense plans, where they discovered a clear knowledge gap around the Denial of Service attacks in use and the defenses needed to maintain availability. The paper provides detail on the attacks in use, suggests realistic defensive architectures and tactics and explains the basic process required to have a chance of defending against a DDoS attack.

The Network Monitoring and Troubleshooting for Dummies Book introduces you to common network performance management (NPM) issues and give you a new way of looking at solving them. This perspective allows you to see your network from your users’ point of view, namely, the services and applications they use and their experience with them.

While the potential value of XenApp is high, that value will not be fully realized if the solution does not perform as needed or expected. This Enterprise Management Associates® (EMA™) white paper reviews the key challenges and requirements for performance management specifically related to Citrix XenApp deployments and examines the Riverbed Performance Management solution in that light.

Midmarket organizations are transforming their IT infrastructure to better accommodate the needs of the business. Two major pieces of this transformation are virtualization and cloud computing, which rely heavily on network performance to ensure success. However, in many cases, these organizations lack the tools to properly monitor virtualized environments in order to meet SLAs. Riverbed has recognized this gap and is delivering a full featured, scalable solution that is priced for the midmarket.

According to industry analyst Enterprise Management Associates (EMA), Riverbed® Cascade© stacks up extremely well against the competition. How well? In particular, Cascade outperforms other application-aware network performance management solutions in such important areas as product strength and cost efficiency. Read the EMA whitepaper to get the full story.

Managing performance in a virtual network and in software-defined networks has remained a critical challenge. VMware and Riverbed have collaborated to provide visibility into these blind spots.

Domain-based Message Authentication, Reporting & Conformance (DMARC) has been created as a standard to help properly authenticate your sends and monitor and report phishers that are trying to send from your name. Read this whitepaper to learn the importance of DMARC and what it does for you.

After a string of high-profile attacks against financial services companies and online retailers, Internet data centers are increasingly the targets of hackers and cybercriminals who view them as vulnerable to new and different kinds of attacks. Read how your can protect your company's valuable data.

It’s no longer sufficient talk about the importance of mobility for IT-enabled operations. Instead, think about the concept of pervasive mobility, where the current generation of traditional devices like notebooks are augmented, and perhaps eventually replaced, by a new armada of consumer-class devices at the edge of the network. In fact, the bulk of information now being created and stored on corporate networks comes from notebooks, tablets and smartphones.

To enable always-on application access and business connectivity, you need a rock-solid network foundation. The increasingly complex, dynamic and fluid relationship between networks and devices requires a new approach to IP Address Management (IPAM) – one that unifies mobile security, address management, automation and self-service to provide actionable network intelligence and a broad span of control. This paper discusses the critical role of IPAM in providing a smarter way to connect mobile devices, applications, virtual environments and clouds.
