Cisco is adding compute power and streamlining edge hardware and software offerings to make SD-WAN easier to deploy and manage.

Taken together enhancements are aimed at helping to better handle growing distributed enterprises but also to help simplify environments—the hardware by allowing users to collapse multiple devices into one, and the software to ease configuration and management of SD-WANs.

On the hardware side, Cisco is adding the 3U, Catalyst 8500-20X6C edge platform to its Catalyst 8000 Edge Platforms Family. It is an edge aggregation device built on the Cisco’s quantum-flow processor (QFP) ASIC and promises more than three times the performance over the existing high-end Catalyst 8500 Series Edge Platform, according to Archana Khetan, head of products in Cisco’s Enterprise Routing group. “With the increased power, customers can support more users and collapse the number of boxes they need to support edge applications as needed,” Khetan said.

The box features up to 6x 40/100GbE and 20 10/1GbE ports and is aimed at campus locations and at aggregation points to act as a central connection hub for distributed sites, Khetan said. It is available now.

The Catalyst 8000 Edge Platforms Family includes three models: the high-end 8500, the 8300 for branch users, and the software-based 8000V for virtual environments. The family can share a feature set that includes advanced routing, SD-WAN, secure-access service edge (SASE). All models run Cisco’s IOS XE operating system software.

Cisco also announced the E-Series M6 compute module for its Unified Computing System servers. The module, available in the first half of the year, promises twice the processing horsepower and 10 times greater I/O capacity compared to previous generations, according to Khetan.  “The M6 is ideal for customer environments where they want to collapse more of their edge compute into the platform and better handle process-intensive business applications and network services,” Khetan said.

Killexams : Cisco observability: What you need to know

Observability may be the latest buzzword in an industry loaded with them, but Cisco will tell you the primary goal of the technology is to help enterprises get a handle on effectively managing distributed resources in ways that have not been possible in the past.

The idea of employing observability tools and applications is a hot idea. Gartner says that by 2024, 30% of enterprises implementing distributed system architectures will have adopted observability techniques to Excellerate digital-business service performance, up from less than 10% in 2020.

“Today’s operational teams have tools for network monitoring, application monitoring, infrastructure monitoring, call monitoring, and more, but they rarely intermingle to provide a cohesive view of what’s going on across the enterprise,” according to Carlos Pereira, Cisco Fellow and chief architect in its Strategy, Incubation & Applications group.

Observability looks to address real problems by gathering information across domains and using it to show how one domain influences another and to predict problem areas or trigger incident management, Pereira said.

“By using observability tools, the business is able to determine the state of its applications with a high degree of certainty and understand how their services impact business key performance indicators and customers’ digital experience,” Gartner wrote in a latest observability report. “Observability enables quick interrogation of a digital service to identify the underlying cause of a performance degradation, even when it has never occurred before.”

At the latest Cisco Live! event in Amsterdam, Pereira provided a preview of the underlying architecture for observability called the Cisco Full-Stack Observability Platform. It’s expected in June, though some details have already been announced.

Killexams : Security and networking highlight innovation at Cisco Live EMEA

Cisco Systems Inc. is now at the center of a massive number of changes in the workplace from hybrid work, geopolitical issues and a continued acceleration to the cloud. I was curious as to see what Cisco had in store for its European customers — especially as the European version of Cisco Live gets underway this week in Amsterdam.

Cisco’s product line is very broad, but most announcements at Cisco Live revolved around security and networking. In my discussions with information technology leaders, these are key investment areas. Security should be obvious as the number and variety of breaches continue to grow. Also, hybrid work has created new security risks as workers no longer sit behind corporate firewalls. The network has become the foundation for digital experiences as all the digital building blocks, such as cloud, mobility and the “internet of things” are connected meaning the network has a direct impact on user and employee experience.

Below are the key announcements by Cisco:


Cisco cyber security index. Security is the most difficult area in corporate IT to get right. Companies spend millions on the most advanced threat protection, but it’s difficult to know if that money is being directed to the right areas and what gaps remain. To help with this, Cisco surveyed 6,700 respondents across 27 markets in companies of all sizes to understand their perceived security readiness in the areas of identity, devices, network, applications and data. The results highlighted how big the security problem is today, since only 15% of companies feel they are mature from a cyber perspective.

The data showed the areas of biggest concern are identity verification and zero trust. This is consistent with my research as users remain the single biggest attack vector for threat actors. Companies rely heavily on training and hope the worker practices good hygiene, but the reality is phishing and other attacks are so good today that even the most savvy user can be fooled. The index gives Cisco and its customers a benchmark to measure to and a focal point for investment.

Zero-trust enhancements. At the show, Cisco announced risk-based authentication, where authentication was dynamically adjusted based on several factors, such as location and type of device Wi-Fi fingerprinting. As an example, workers might be granted access to certain systems when at home, but if they walk across the street to a coffee shop, access is denied. That automates many of the decision points that users would have had to do in the past. In turn, that removes the burden from the users having to evaluate how and when to connect to corporate resources depending on their situation.

Business risk observability. This solution combines information from many Cisco products and generates an application-based business risk score to mitigate vulnerabilities. Data from business transactions (AppDynamics), vulnerability scores (Kenna), API security (Panoptica) and threat intelligence (Talos) are combined to create the risk score. It’s important to note this isn’t just classifying apps as critical, high or low but measures the impact of external entities and the relation to the business. I have long believed that Cisco has wasted its opportunity in security because it has never managed to leverage its massive portfolio. This is an excellent example of what Cisco is capable of in creating a “1+1 = 3” value proposition for customers that deploy Cisco everywhere.


ThousandEyes open telemetry. Cisco is making the massive data set in ThousandEyes available to be integrated into other systems. As an example, ThousandEyes and AppDynamics are now integrated so when an app is performing poorly, as identified by AppDynamics, ThousandEyes can be used to quickly identify if there is a network issue causing it.

The open telemetry does three things for customers. First, the data can be retained for as long as the customer wants it. This allows for baselines to compared over months or even years. Second, visualizations and correlations can be built across diverse data sets. Lastly, customers can perform deeper analytics by combining ThousandEyes data with their own data sets. Some examples of integrations that might useful are Splunk and Grafana.

Updates to Cisco+ Secure Connect. This was launched six months ago and is Cisco’s secure access service edge solution. Powered by the popular Meraki dashboard, it delivers an end-to-end view of the environment that spans from the premises out to the cloud. The update at Cisco Live is Cisco+ Secure Connect now supports Viptela-based software-defined wide-area networks in addition to Meraki. This allows customers to set policies once and push them out across Meraki and Viptela. It’s not full configuration support yet, but policy administration is a big headache for companies that Cisco has now made simpler.

New multi-access edge network products for industrial networks. After a decade of talking about the coming together of IT and operational technology or OT, it appears that businesses are finally bringing these environments together, and this creates some interesting requirements for network equipment. The products need to be built for the rigors of industrial use cases, such as being weatherproof and fan-less but built with enterprise manageability.

At the show, Cisco announced its new Catalyst IE3100 compact, ruggedized switch series. These are Layer Two switches that can be used in space-constrained areas. They run IOS-XE giving them the same feature set as the company network allowing polices and performance to be consistent across OT and IT environments. Cisco also announced two wireless devices. The IW9165E is a wireless client that provides resilient connectivity for moving vehicles. Cisco also announced its IE9165D, which provides wireless backhaul capabilities.

The network announcements show continued investment in an area in which Cisco has been a market leader for decades. The industrial market is unique to Cisco because none of its traditional competitors has made investments in OT connectivity. As IT-OT integration goes mainstream, this should help Cisco keep its large market share lead.

The security updates play a different role for Cisco. Cyber has been red-hot over the past few years and many of Cisco’s competitors have seen higher growth rates than Cisco. Trying to compete on products and features, which it has in the past, is a mistake for Cisco because it doesn’t bring the “palette” advantage. Business risk observability is a great start, since it combines data from several Cisco products, but this must now kickstart further integrations with the network, collaboration and all parts of its portfolio.

Killexams : Cisco security upgrades strengthen access control, risk analysis

Cisco has strengthened some of its key security software packages with an eye toward better protecting distributed enterprise resources.

Specifically, Cisco added more intelligence to its Duo access-protection software and introduced a new application called Business Risk Observability that can help enterprises measure the impact of security risks on their core applications. The company also enhanced its secure access service edge (SASE) offering by expanding its SD-WAN integration options.

Cisco Duo enhancements strengthen access control

The cloud-based Duo service helps protect organisations against cyber breaches by using adaptive multi-factor authentication (MFA) to verify the identity of users and the health of their devices before granting access to applications.

Cisco paid US$2.35 billion in 2018 for Duo and has been enhancing and expanding its use across its product line. Most recently, Cisco rolled out Duo Passwordless Authentication with support for biometric authentication, including Microsoft Windows and Apple Macs.

Passwordless authentication is aimed at reducing the risk of phishing attacks and their ability to utilise stolen passwords as well as addressing MFA fatigue.

With that in mind, the Duo service now also supports features called Remembered Devices and Wi-Fi Fingerprint that allow users to avoid repeated authentications as they move from application to application in trusted operations.

Another new feature, called Checked Push, enables Duo to recognise behaviour from known attack patterns and require the user to enter a code instead of just pushing a button to confirm.

Using MFA fatigue as an attack vector has led to some high profile breaches, said Tom Gillis, senior vice president and general manager of security at Cisco.

“Attackers have built an attack that will look like an MFA request on your phone, but it's actually a way to get into the network,” he said. “So rather than have users mindlessly clicking through MFA requests, we have added the ability to intelligently and selectively let customers set a security policy that reduces that possibility.”
