Menlo Security Raises $25 million for Isolation Platform

Menlo Security emerged from stealth to unveil its Isolation Platform, a new technology that eliminates the threat of malware from key attack vectors, including Web and email.

The solution does not use endpoint software. Instead, the Menlo Security Isolation Platform isolates and executes all Web content in the cloud and away from the endpoint. It uses patent-pending, clientless rendering technology, Adaptive Clientless Rendering (ACR), to deliver a non-executable, malware-free copy of the user’s session to their native browser, creating a transparent user experience.

The Menlo Security Isolation Platform is available now as a public cloud-based service or as a virtual appliance for on-premise deployment. The Platform is compatible with any hardware (desktop, laptop, tablet, smartphone), any OS (Windows, MacOS, iOS, Android) and any browser (IE, Chrome, Safari, FireFox).

Menlo Security also announced $25 million in Series B funding, led by new investor Sutter Hill Ventures and joined by existing investors General Catalyst, Osage University Partners and Engineering Capital.

“Organizations and individuals should be able to interact online without the fear of being compromised,” said Amir Ben-Efraim, co-founder and CEO of Menlo Security. “By focusing on ease of deployment and a seamless user experience, the team at Menlo Security has reinvented isolation as a highly usable and scalable front line of defense against malware.”

Prior to emerging from stealth, Menlo Security in November 2014 announced $10.5 million in Series A funding to reinvent security. The new round of financing brings the total company funding to $35.5 million. Additionally, Stefan Dyckerhoff, managing director at Sutter Hill Ventures, is joining the Menlo Security’s board of directors.

ONOS Advances its SDN Operating System with 3rd Release

A third version of the Open Network Operating System (ONOS), named Cardinal, has been released, adding several significant enhancements in the areas of Application Intent Framework, southbound interfaces and new distributed core features and capabilities.

ONOS, which was first released in December 2014, is currently deployed live in three research and education networks worldwide with more to come in Europe and Asia. These include SDN-IP peering application deployments at Internet2 in the U.S. and FIU/AmLight to South America as well as a BGP Peering Router deployment at CSIRO, Australia. It is also being used to enable proof-of-concept (PoCs) of multi-layer IP/optical networks and for the migration to SDN using the SDN-IP peering application.

Some Cardinal highlights:

  • Improves performance for flow operations, application intent processing and network topology maintenance by more than 25 percent.
  • Creates several new uses by enabling the central office to be re-architected as a data center (CORD).
  • Cardinal’s Application Intent Framework supports all the key solution POCs that will be demonstrated at the Open Networking Summit (ONS2015) conference with extensions such as MPLS and tunnel support added to the framework to support a wide variety of SDN applications.
  • A new flow-objective subsystem in the distributed core enables device agnostic SDN deployment. It allows apps to use a variety of OpenFlow switches with support for multiple tables without being concerned about the device specific details. It is definitely a big step forward towards the inter-operability and elimination of the solution silos that exist today.
  • At the southbound, NETCONF and PCEP interfaces are now available, and the TL1 interface will be used by two vendors for a few solution POCs although TL1 is not yet available from ONOS for open source distribution.

“The ONOS team has been running on all cylinders and continues to increase momentum with the help from the community,” said Bill Snow, vice president of Engineering at ON.Lab. ”The code base continues to add functionality, while keeping code quality high and continually improving performance. ONOS’ use cases really show its unique capabilities to transform service provider and mission critical networks.”

Massive Data Breach Raises Questions about Perimeter Defense

The U.S. Office of Personnel Management (OPM) confirmed details of a massive data breach potentially impacting the personal records of 4 million current and past employees of the U.S. government.

OPM said it became aware of a cybersecurity intrusion affecting its information technology (IT) systems and data in April 2015 while it was in the process of updating its cybersecurity posture, adding tools and capabilities to its various networks.

Media reports attributed the attack to a Chinese state-backed hacker group known as “Deep Panda”, although both the OPM and FBI declined to comment on the specifics. Media reports also suggest that the stolen data was not encrypted.

The OPM network is believed to have been protected by the second generation intrusion detection and prevention system, known as EINSTEIN 2. A planned upgrade to EINSTEIN 3, which will be integrated as a Managed Security Service with leading Internet Service Providers (ISP), is being accelerated so as to cover all government network by the end of 2016.

Outside commentators noted that relying on a perimeter IDS, even one benefiting from signatures captured by national security agencies, may be an insufficient strategy for 2015 and beyond, compared to other solutions emphasizing network visibility for advanced persistent threats. A Bloomberg story posted Michael A Riley quotes a senior fellow in cybersecurity at the Center for Strategic and International Studies in Washington as saying Einstein 3 is already obsolete and that the commercial security industry moving away from this type of perimeter defense.

Avi Networks Integrates Cloud ADC with Cisco ACI

Avi Networks, a start-up based in Sunnyvale, California, has integrated its Cloud Application Delivery Controller with Cisco's Application Centric Infrastructure (ACI).

Avi Networks, which was founded by key engineers behind Cisco's Nexus data center platforms, offers a software-only load balancer that adopts the same approach taken by large cloud service providers, such as Amazon, Facebook and Google, in that it runs entirely on x86.  The hyperscale ADC separates the control plane from the data plane.  Avi is also bringing traffic analytics into its Layer 7 switching, enabling application flows to dynamically adapt to traffic conditions..

The newly announced integration with Cisco ACI establishes interoperability with the Cisco Application Policy Infrastructure Controller (APIC) using RESTful APIs. Avi use a common architecture as Cisco, including unified management and control planes, as well as the ability to scale data plane resources elastically, on-demand as application requirements dictate. The company says this approach provides end-users with better application delivery, security and load balancing, in addition to real-time visibility, monitoring, and integrated (inline) analytics of their on-premise and cloud-based applications.

“We are excited to announce the availability of the integration with Cisco ACI, which is one of the most important data center and cloud networking solutions,” said Umesh Mahajan, CEO of Avi Networks. “The Cisco ACI is a true application driven environment and it requires a complementary approach to application delivery to guarantee the proper end-user experience and application performance, which are fundamental for success in today’s era of cloud, mobile and virtualization technologies.”

“Cisco ACI has been built with a broad and deep ecosystem of partners to give our customers freedom of choice among vendors,” said Ish Limkakeng, VP, Cisco. “We are pleased to have Avi Networks join our ecosystem and to have them share our vision for automation and agility in the data center.”

Avi also cites its Inline Analytics capability as a key differentiator.  An inline analytics module integrated within the company's ADC aligns with the centralized and deep network infrastructure visibility available through the Cisco APIC solution.

Dell'Oro: Cisco Gains Share in L2-3 Ethernet Switch Market

The Layer 2-3 Ethernet Switch market declined nearly $1 billion in the first quarter 2015 to slightly more than $5.5 billion, according to a new report from Dell'Oro Group.

"Seasonality, especially since China has become a larger part of the market caused Ethernet Switch revenues to be down significantly in 1Q15. Despite the strong sequential market decline, Cisco gained revenue share year-over-year," said Alan Weckel, Vice President of Ethernet Switch market research at Dell'Oro Group. "Campus switching has begun an upgrade cycle to support next generation wireless LAN access points using new Multi-Gigabit technology as a catalyst. Campus switching will also get a boost from E-Rate during the summer. As we transition to the end of 2015, the data center will begin an upgrade cycle to 25 GE for server access with 100 GE starting to ramp to significant volumes. The market will also be absorbing both HP's announcement to divest H3C and Avago's announcement to acquire Broadcom. It has been almost a decade since we have seen so much vendor repositioning in the market," stated Weckel.

The report also indicates that Cisco Systems, Huawei Technologies, and Hewlett-Packard (H3C) were the top three vendors in revenue rank in China during the first quarter 2015.

Blueprint: Enabling Smart Software Defined Networks

by Seong Kim, System Architect in AMD’s Embedded Networking Division

The networking and communications industry is at a critical inflection point as it looks to embrace new technologies such as software-defined networking (SDN) and network function virtualization (NFV). While there are significant advantages to deploying a software-defined network, there are challenges as well. The implementation of SDN and NFV requires revamping network components and structures, and adopting new approaches to writing software for network management function.

The hosting of SDN and NFV middleware and network management software on industry-standard processors is now being handled by modern multi-processor heterogeneous system architectures that incorporate both CPU and GPU resources within a single SOC.

What’s been missing until recently is a holistic view of networks and the technology providing a standardized separation of the control and data planes. SDN provides this capability, and can efficiently enable data center and service providers to manage network configuration, management, routing and policy enforcement for their evolving multi-tenant heterogeneous networks.

As defined by the Open Networking Foundation, SDN decouples the network control and forwarding functions, enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.
Unlike server virtualization, which enables sharing of a single physical resource by many users or entities, virtualizing network resources enables a consolidation of different physical resources by overlaying virtual layers of networks on heterogeneous networks, resulting in a unified, logically homogenous network. Figure 1 describes three requirements that commonly define SDN architecture.

SDN Trends and Challenges

There are several different SDN deployment scenarios in the industry, although the original SDN concept proposes to have a centralized control plane with only the data plane remaining in the network.

On the controller implementation, three basic topologies are being considered in the industry. The first is a centralized topology where one SDN controller controls all the switches in the network. This approach, however, incurs a higher risk of failure since it makes the central controller a single point of failure for the network. The second topology being investigated is the so-called distributed-centralized architecture. In this approach multiple “regional” SDN controllers, each controlling a subset of the network, communicate with the (global) central controller. This architecture eliminates single points of failure since one controller can take over the function of a failed controller. Finally, Orion  proposes a hierarchical topology that may provide better network scalability.

Apart from the controller, the data plane can also become a challenge with the transition to SDN, because traditional switching and/or forwarding devices/ASICs will not be able to easily support SDN traffic due to evolving standards. Hence the need to have a hybrid approach. Specifically, a portion of the network (e.g., the access network) can be SDN enabled while the other portion (e.g., the core network) can remain as a ‘traditional’ network . Thus traditional platforms are located in the intermediate nodes, acting as a big pipe, and SDN-enabled platforms serve as the switch and routing platforms. With this approach, an SDN network may be enabled immediately without requiring the overhaul of the entire network.

Challenges in SDN are still emerging, as the definition of SDN continues to evolve. The scale-out network paradigm is evolving as well. Due to these uncertainties, abstraction mechanisms from different vendors will compete or co-exist. In addition, creation of SDN controllers and switches requires resolution of design challenges in many hardware platforms.

The data center environment is the most common use case for SDN. In the traditional data center network, there are ToR (Top of Rack), EoR (End of Row), aggregation and core switches. Multi-tier networking is a common configuration. To increase data center network manageability, SDN can abstract physical elements and represent them as logical elements using software. It treats all network elements as one large resource across multiple network segments. Therefore it can provide complete visibility of the network and manage policies across network nodes connected to virtual and physical switches.

Figure 2 shows a traditional multi-tier data center network and how an SDN controller can manage the entire network from a centralized location.

SDN’s basic tenet is to remove vendor-specific dependencies, reduce complexity and improve control, allowing the network to quickly adapt to changes in business needs. Other key SDN requirements are the disaggregation of control and data planes, and the integration of strong compute and packet processing capabilities. Companies are now collaborating to demonstrate the feasibility of a complete SDN solution utilizing the unique compute capabilities and power efficiency of heterogeneous, general purpose processors.

Software Enablement for SDN

One such demonstration of the integration needed to enable SDN is an ETSI NFV proof-of-concept. In this proof of concept, several companies demonstrated the integration of a Data Plane Development Kit (DPDK) on an x86 platform and Open Data Plane (ODP) on an ARM-based platform running OpenStack. The DPDK and ODP middleware enables fast packet I/O for general purpose CPU platforms eliminating the typical bottleneck in the data path when there is no user space pass-through enablement. This middleware software is a must-have to enable an SDN solution, providing a unified interface to various platforms including x86 and ARM64 platforms.

High Compute Power at a Low Power Envelope

An SDN controller needs to have strong compute capability to handle large amounts of control traffic coming from many SDN switches – each individual flow needs handling by the central SDN controller. This brings concerns regarding the SDN controller in terms of performance and single point of failure.

There are different architectures proposed in the industry to mitigate the load on the central controller. One example is a distributed-centralized controller which has several SDN controllers, each managing a subsection of the network, with an additional control layer managing these regional controllers. This architecture requires smart, distributed and powerful compute capabilities throughout the entire network of SDN controllers. Different nodes, including SDN switch nodes, require different levels of performance and power. SDN implementations benefit from vendor platforms that offer a range of performance capabilities, matching the appropriate level of resources at the necessary point in the network design.

Security Enhancements

There is a growing need for security, and as the amount of control traffic increases, the needs of crypto acceleration or offload increase together. By offloading crypto operation to acceleration engines such as CCP (Crypto Co-processor) on a CPU or GPU, the system level performance can be maintained without compromising compute performance.

Deep Packet Inspection (DPI) - Understanting Network Traffic Flow

In order for an SDN controller to manage the network and associated policies, it requires a good ‘understanding’ of networking traffic. Centralized or distributed SDN architectures can support a deep understanding of traffic by collecting sets of packets from a traffic flow and analyzing them. There are two different ways to support this requirement.

Option 1—Based on the assumption of having a big pipe/channel between SDN switches and SDN controller, all of the deep packet inspection or application recognition can be done in the central controller with a powerful DPI engine.

Option 2—A small DPI engine can be implemented in the distributed SDN switches. These switches perform a basic deep packet inspection, then report the results or send only streams of important traffic. As we have seen, the latter case requires cheaper and simpler implementation to meet the basic SDN tenet.

Low cost and low power processors can be used for DPI applications. The combination of CPUs and GPUs as found in heterogeneous architectures, the latter being highly optimized for highly parallel programmable applications, provides a significant performance advantage.

I/O Integration

The main processor for SDN requires high speed I/O interfaces, for example, embedded network interfaces such as 1G, 10GE, and PCIe. This can lower system cost and ease system design complexity.

Software

Complicating the development of new SDN solutions is the continuing evolution of standards. Throughout the industry, there are different approaches to enabling network virtualization (for example, VXLAN and NVGRE), and these standards continue to evolve as they move to the next phases. In order to meet the requirements of these evolving standards – and any emerging network overlaying protocols – platforms must be able to provide flexibility and ease of programmability. As an example, the transition from the OpenFlow1.0 spec to the OpenFlow revision 1.3 significantly increased complexity as it aimed to support many types of networking functions and protocols.

Platform Needs

Modern heterogeneous compute platforms contain the following three major function blocks:
General purpose, programmable scalar (CPU) and vector processing cores (GPU)
High-performance bus
Common, low-latency memory model

Leading heterogeneous designs are critical to maximizing throughput. For example, on AMD platforms incorporating Heterogeneous Systems Architecture (HSA), the CPU hands over only the pointers of the data blocks to the GPU. The GPU takes the pointers and processes the data block in the specific memory location and hands them back to the CPU. HSA ensures cache coherency between the CPU and the GPU. Figure 3 depicts an overview of this architecture.

 GPUs are extremely efficient for parallel processing applications, and they can also be used for crypto operations, DPI, classification, compression and other applications. In the case of crypto operations, the CPU doesn’t have to get involved in the data plane crypto operation directly. With this architecture, the system level performance can be maintained even when the amount of traffic needing encryption or decryption increases. In a heterogeneous capable processor, software can selectively accelerate or offload CPU compute-intensive operations to the GPU. Here are a few additional functions that can be accelerated or offloaded to the GPU:

DPI: Implement RegEx engine
Security (such as IPSec) operations: RSA, crypto operation
Compression operation for distributed storage applications


 Figure  4 shows a number of different networking use cases and examples of where different levels of embedded processors integrate into the solution.

Conclusion

SDN introduces a new approach to network resource utilization and management, and each networking vendor in the market is looking for its own way to build SDN solutions. One key action that needs to be taken to enable SDN is to open up the intelligence of switches and routers to enable the abstraction of proprietary vendor technologies.

Mega data center players (Amazon, Google, Facebook and the like) are implementing technologies that will allow them to enable greater flexibility and lower costs. Amazon and Google are building their own networking (white box) switches so that they don’t have to rely on the platforms produced by OEM vendors. Facebook is driving the Open Compute Platform (OCP) to develop specifications for open architecture switches that will be manufactured by low-cost original design manufacturers (ODMs) . The open architecture approach from Facebook is creating an ecosystem where standard, high volume commodity platforms could be used to minimize CAPEX and OPEX costs.

SDN will drive the industry toward a more software-centric architecture and implementation. Thus, in this environment, OEMs find it more difficult to provide platform differentiators. With SDN, the need for less expensive and easy-to-access hardware becomes paramount, and platform-specific, value-added services is deprioritized.
