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 Boost 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 exact 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 exact 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 : 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 SASE offering by expanding its SD-WAN integration options.

Cisco Duo enhancements strengthen access control

The cloud-based Duo service helps protect organizations 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 $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 utilize 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 Tested Push, enables Duo to recognize behavior 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.”

Killexams : Cisco beats earnings and revenue estimates, boosts full-year guidance
Cisco supply chain issues continue to ease

watch now

Cisco reported better-than-expected fiscal second-quarter results on Wednesday and lifted its forecast for the full year. Shares of the computer networking company initially jumped in extended trading before paring most of their gains.

Here's how the company did:

  • Earnings: 88 cents per share, adjusted, vs. 86 cents per share as expected by analysts, according to Refinitiv.
  • Revenue: $13.59 billion vs. $13.43 billion as expected by analysts, according to Refinitiv.

Cisco's total revenue grew 7% year over year in the quarter, which ended Jan. 28, according to a statement. Net income fell about 7% to $2.77 billion.

Some components that go in Cisco's hardware products remain constraints, but the company did see an improvement across the board, CEO Chuck Robbins said on a conference call with analysts.

"Based on the sequentials that we saw, demand remains stable," he said, although he added some sales cycles are longer than usual.

Cisco's public sector business performed more strongly than it has historically, while in the service provider category, some customers are adjusting to the better delivery of the company's products into their environments, Robbins said.

The company called for fiscal third-quarter adjusted earnings of 96 cents to 98 cents per share and 11% to 13% revenue growth. Analysts surveyed by Refinitiv had been looking for adjusted earnings per share of 89 cents and revenue of $13.58 billion, which implies almost 6% growth.

Cisco lifted its guidance for the 2023 fiscal year, and now expects $3.73 to $3.78 in adjusted earnings per share and 9% to 10.5% revenue growth. Both numbers are well ahead of analysts' estimates.

But Cisco said its backlog increased year over year. The backlog for both hardware and software is still considerably higher than usual for Cisco because of limited supply availability, said Scott Herren, Cisco's finance chief.

"We continue to have very low order cancellation rates, which remain below pre-pandemic levels," Herren said.

Logistics costs have come down somewhat, he said.

In the fiscal second quarter Cisco's largest business segment, Secure, Agile Networks, featuring networking switches for data centers, posted $6.75 billion in revenue. That was up 14% and more than the $6.52 billion consensus among analysts polled by StreetAccount.

The Internet for the Future unit, which includes routed optical networking hardware, contributed $1.31 billion, down 1% and just below the $1.32 billion StreetAccount consensus.

Revenue from Cisco's Collaboration division containing Webex fell by 10% to $958 million, falling short of StreetAccount's $1.06 billion consensus.

In the quarter, Cisco announced updates to its AppDynamics cloud software for application monitoring and disclosed a restructuring plan that includes changes to its real estate portfolio.

Notwithstanding the after-hours move, Cisco shares have inched about 2% higher, while the S&P 500 index is up 8% in the same time period.

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 : Bluetooth tracker Tile is taking a new approach to stopping thieves and stalkers

Tile has a bunch of tracker sizes and shapes.


Life360's Bluetooth tagging device Tile is launching a new anti-theft mode designed to get around a tricky issue: criminals knowing when an item they've stolen is being tracked.

The new anti-theft mode makes a user's Tile undetectable in Scan and Secure, the company's in-app feature that allows iPhone and Android users to locate nearby Tiles. That feature was initially launched to combat the rise in stalking with Bluetooth tagging devices, but now the company say that approach hasn't stopped stalking and has, if anything, made a criminal's job easier to get away with.

"It seemed like the real problem of stalking wasn't actually being necessarily solved," said Life360 CEO Chris Hulls. "But what was happening was that there's this new vector that's opening up for thieves, where so much of the reason people buy Bluetooth tags to begin with is to protect their items from theft. And now, if you have a Tile or an AirTag, a smart thief will almost certainly be able to find it."

That's because if a thief learns there is a Bluetooth tag on an item that they stole, they're able to easily remove the tag and prevent victims from tracking down valuables.

Bluetooth tagging devices like Life360's Tile, Apple's AirTag and Samsung's Galaxy SmartTag have come under pressure to increase safety features as stalking cases rose. But robberies are also on the rise throughout the U.S., and according to Hulls, there's been a negligible number of stalking cases. During the first half of 2022, there was a 5.5% increase in robberies throughout the country, according to the Council on Criminal Justice.

"Theft is the primary reason people buy these products," Hulls said. "Our new anti-theft mode is a tradeoff. ... It gives consumers choice, they can turn off all the anti-stalking features, so their Tiles become invisible," he added.

Police warn of Apple AirTags being used to stalk people

Tile is taking a new approach to stalking prevention. If a user chooses to use the anti-theft mode, they must go through an ID verification process, which will register the user with Tile and sync their ID with their account.

"From our research, the real issue with stalkers is how do you remove anonymity?" he said.

Scan and Secure didn't address that issue, he said, and it didn't have any enforcement mechanism. That's changing now too, with Life360 threatening stalkers with a $1 million penalty the company will pursue against any individual convicted in a court of law for using Tile devices to illegally track any individual without their knowledge or consent. If someone is convicted in court for stalking using Tile, in which the ID verification makes prosecution easier, Tile would sue that person for violating the terms and services.

But there is a user privacy issue in the changes as well. Life360 is increasing collaboration with law enforcement so that if anti-theft mode is enabled, users must acknowledge that personal information can and will be shared with law enforcement at the company's discretion, even without a subpoena, to aid in the investigation and prosecution of suspected stalking.

"So much of why people buy these devices to begin with is to protect against theft. So, we think this really threads the needle elegantly," Hulls said.  

Consumer technology advocates weigh in on safety and security changes

Technology safety advocates aren't convinced.

Kathleen Moriarty, chief technology officer at the Center for Internet Security, said via email that a closer tie to identity should Boost the integrity of the solution by adding in a human factor and sense of responsibility, but as is the case with any new release, "limits and boundaries will be tested in unexpected ways."

For example, if a Tile can be discovered by its authorized owner, to track down the belonging in which it was placed, the Tile is emanating a signal to make that possible. Although the application designed for Tile use will only make that visible to the Tile owner, the signal may be discoverable with other tools.

"Without insight into the technical details, the protections to prevent detection are not clear. Typically confidence from technologists is higher for standards-based solutions due to the rigorous review process by a number of experts. The solution holds promise and time will tell as it gets tested in real-world scenarios," she said.

Adam Dodge, CEO of digital safety education company EndTAB and a member of the World Economic Forum's Digital Justice Advisory Committee, was more critical of the approach in an email exchange. "This update denies stalking victims access to the most essential of safety measures, the ability to verify and locate a tracker to stop the abuse," Dodge wrote.

He says Life360's new safety commitments — identify verification, fines and promises to cooperate with law enforcement — do not offset the increased risk created for victims, and he noted that the features and new company policies only come into play if the Tile tracker is found, something that anti-theft mode now makes much less likely. 

"We have to remember that bad actors care most about getting caught. From that perspective, this new feature is a homerun," Dodge said. "I'd rather see Tile's new commitments to safety implemented on their own, as opposed to a way to blunt the risks created with anti-theft mode." 

In his view, if the problem of stalking wasn't being solved, companies like Life360 should solve for it specifically through innovation and new safety features. "The irony is that, by making Tile trackers undetectable, it is now easier for stalkers to stay anonymous," Dodge wrote. 

This story has been updated to include comments from Adam Dodge, CEO of EndTAB, and Kathleen Moriarty, chief technology officer at the Center for Internet Security.

Killexams : Markalunas: ‘Do nothing’ approach to transportation

Listening to the comments of the Aspen City Council members at their meeting of Feb. 13 was a revelation to me and the general public of an exercise in a “do nothing” policy by our present council in public transportation options.

It’s all talk and no constructive action. That’s the way it’s been for the last 20 or more years since we demonstrated the possibilities of a light-rail option for our Roaring Fork Valley. Yes, indeed! “It’s all blow and no go!” by our current Aspen City Council.

With our present “do nothing” council, Aspen citizens, working folks, and visitors will never experience a first-class public transportation system.

Killexams : New approach to diabetes management helps Boost patient outcomes

A new study by Western Sydney University researchers has found that a short 15–20 minute discussion between a local endocrinologist and general practitioner (GP) in Sydney's south west is improving the care of people with complex type 2 diabetes.

Published in the International Journal of Integrated Care, the three-year study is the first evaluation of "patient-free" diabetes case conferencing—a model where, with the patient's consent, an endocrinologist visits a GP practice, alongside a practice nurse or diabetes educator, to collaborate on the care of patients to develop a joint management plan for the patient.

The study found (HbA1c), , weight, as well as other cardiovascular risk factors all improved following the three-year trial involving more than 600 patients with type 2 diabetes from 40 general practices across south western Sydney.

Blood glucose results substantially improved between 2017 and 2020, with more than a third (37%) of patients within the target range compared with just one in five (20%) before the program.

In addition, more than three quarters (77%) of patients were recording within the target range on follow-up, compared with less than half of patients (47%) in 2017.

Co-author Professor David Simmons, Head of Endocrinology at Campbelltown Hospital and from the University's School of Medicine said the study found the model made a significant contribution to diabetes management in primary care settings.

"Diabetes is a significant health issue in south western Sydney and it is critical we work together to find more effective, integrated and streamlined ways to manage patients and Boost outcomes," said Professor Simmons.

"The findings from this study show how a collaborative discussion between a GP and endocrinologist where the patient is not present, can be one of the most effective integrated diabetes care interventions.

"This can allow the GP to continue to care for the patient in the practice, avoiding the need to see an endocrinologist in person. The collaboration also helps build the GP's expertise in managing their other complex patients and the endocrinologist learns more about the patient from the GP which facilitates truly patient-centered care."

The findings add to the evidence suggesting that case conferencing programs can help close the gaps in service provision such as barriers between different settings, Boost the patient experience by accommodating more complex cases in primary care and reduce duplication of care.

Co-author Ms. Reetu Zarora, a Ph.D. student at Western Sydney University, highlighted how the model of care doesn't just save time and resources in primary care settings but also has a positive impact more broadly on the health system.

"This is a real win-win-win for patients, GPs and the health system: patients get specialist input into their care without any extra time or cost, GPs can continue to manage their patients using their extra knowledge, and the health system has less demand on hospital clinics, potentially reducing and preventing hospitalizations in people with complex diabetes compared with usual care. This should reduce -related health issues," said Ms. Zarora.

"In addition, the case conferencing model through the study was shown to be suitable in both urban and rural settings where a number of participating practices support large multi-ethnic populations with varying socioeconomic status.

"This points to the potential for broader applications of the model of care including in regions with resource restraints and diverse populations."
