“Powering Hybrid Work” in Financial Services

Cisco Prep, Cisco Exam Prep, Cisco Certification, Cisco Learning, Cisco Guides, Cisco Skills, Cisco Jobs

The question that I get asked most often by financial services CXO’s is “how do we move beyond just ‘supporting’ Hybrid Work to ‘powering’ Hybrid Work with the right technology stack so that we can address the challenges of attracting and engaging an evolving workforce and keep the organization moving forward in an agile and sustainable way.”

Throughout the pandemic, financial services firms have been prioritizing health and safety of their employees by implementing hybrid work whilst abiding by guidelines and regulations. However, not everyone has had success with their “hybrid work” deployments. Those that have got it right to some extent are realizing the benefits

A large number of financial services firms have struggled to implement “an optimum workable hybrid work model”. The challenge is they have tried to retrofit “remote work implementations” with technology upgrades and add-on’s as guided by their many different technology partners.

Hybrid Work in the context of financial services can be defined as an employee centric, business transformative approach that designs the work experience around and for the employee, wherever they are. It empowers employees to work onsite, offsite, and move between locations with uniform access to all the business tools and resources in a highly secure, compliant and efficient manner thus promoting inclusiveness, engagement, and well-being for all employees while driving employee performance, business productivity and talent retention.

While a future-proofed technology stack is a critical pillar of the hybrid work model, getting Hybrid Work to work also requires reimagining current and emerging operating models and optimizing them such that employee engagement, experience and well-being is enhanced while financial services delivery just keeps getting better with more delighted customers.

Financial services firms that have their operating models reimagined/transformed to support the hybrid work model have the first mover advantage of becoming fully resilient businesses, ready to weather any storm.

A “Hybrid Work Powered” operating model for financial services firms should at the least have the  following 5 characteristics :

Cisco Prep, Cisco Exam Prep, Cisco Certification, Cisco Learning, Cisco Guides, Cisco Skills, Cisco Jobs
1. INCLUSIVE – offering equal experiences for everyone. Enables firms to provide a work environment where every employee can participate fully and be seen and heard equally.

2. FLEXIBLE – adapting to any work style, role, and environment. Enables employees spread across different office locations, types (home etc.), time zones and even countries, working at different hours have access to flexible tools that can address their different needs while adapting to their work styles, roles, and devices.

3. SUPPORTIVE – focusing on safety, empathy, and well-being.  Enables firms to promote a supportive mindset throughout every level of the organization thus ensuring that employees are comfortable with ways of working and feel safe, secure, supported, included, and cared.

4. SECURE – being secure by design, private by default.  Enables employees to have worry-free access to reliable and secure connectivity and secure app experiences thus ensuring all team members can work and collaborate with confidence anywhere they choose to work and have consistent, uninterrupted access to the required applications.

5. MANAGED – delivering modern infrastructure, frictionless administration. Enables IT teams to operate and manage the complex and dynamic hybrid work environment, using an approach known as full-stack observability which delivers optimized user experiences and enhanced enterprise technology management.

To get “hybrid work to work”, financial services firms need to reimagine/transform their operating models to deliver the key characteristics mentioned earlier and not just depend on “retrofitting” their existing IT stacks with hybrid work enabled “siloed” products.

Investing in a “future-proofed hybrid work technology stack” such as Cisco’s “secure-by-design*” Hybrid Work Solution Technology Stack enables financial services firms to reimagine/transform their operating model thus moving past “supporting” to “powering” Hybrid Work in a highly secure and compliant manner by empowering workers to work from anywhere, at home or in the office while also providing a positive outcome for every business sponsor and stakeholder (HR, Facilities, IT etc.) who are involved in defining and implementing the financial services firms hybrid work strategy.

Continuous value delivered with new Cisco SD-WAN innovations

IT teams need agile delivery to keep pace with business demands. Today, enterprises are in the process of transitioning to a hybrid workforce, another rapid pivot that requires agile delivery. It’s essential to adapt to the new paradigm and in doing so, seek to minimize costs while still improving productivity, security, and the user experience. Cisco software platforms, like Cisco SD-WAN provide continuous value with new capabilities enabled in software.

Our latest Enterprise Networking release helps with this transition to hybrid work and provides value with innovations that provide greater integration that can reduce OpEx and CapEx spending and simplify operations. See the details below on new features in this release to help your IT team increase business agility and deliver more value for your organization.

First Cloud OnRamp for SaaS to optimize Webex experience

To improve and enhance the user experience for organizations, in our latest release (17.7) we are announcing Cisco SD-WAN Cloud OnRamp for SaaS integration with Webex. Cisco SD-WAN is the first solution to provide this level of integration and automation.

Cisco enables users to optimize Webex connectivity and performance when using Cisco SD-WAN. It does this by continuously monitoring all possible paths to Webex, and intelligently routing cloud application traffic to the best performing path, providing a fast, secure, and reliable end-user experience – and without human intervention.

The ultimate value for the users is that Cloud OnRamp for SaaS delivers path optimization and policy automation for Webex, so enterprises will be able to deliver a better application experience for their customers and employees.

Simplify CUBE functionality embedded in routers with Cisco SD-WAN

The new release enables native Cisco Unified Border Element (CUBE) support on Cisco enterprise routing platforms. CUBE is an enterprise-class Session Border Controller (SBC) performing critical voice routing, security, interworking and session management functions. Supported platforms include: ISR 4000, ISR 1100, and Catalyst 8200 as well as other ASR models.

The integration of this functionality into Cisco SD-WAN empowers customers to leverage the edge platforms to route collaboration application traffic between SD-WAN enabled nodes either within an enterprise (for on-prem deployments) or private / public cloud-based solutions. Customers can enable SBC functionality on their existing SD-WAN platforms allowing them to consolidate capabilities into a single platform, eliminating the need for an additional appliance. This integration reduces the number of platforms to purchase, license, power and manage; simplifies network architecture; and lowers costs and complexity.

What DevSecOps Means for Your CI/CD Pipeline

The CI/CD (Continuous Integration/Continuous Deployment) pipeline is a major ingredient of the DevOps recipe. As a DevSecOps practitioner, you need to consider the security implications for this pipeline. In this article, we will examine key items to think about when it comes to DevSecOps and CI/CD.

The type of CI/CD pipeline you choose—whether it’s managed, open source, or a bespoke solution that you build in-house—will impact whether certain security features are available to you out of the box, or require focused attention to implement.

Let’s dive in

Secret management for your CI/CD pipeline

Your CI/CD pipeline has the keys to the kingdom: it can provision infrastructure and deploy workloads across your system. From a security perspective, the CI/CD pipeline should be the only way to perform these actions. To manage your infrastructure, the CI/CD pipeline needs the credentials to access cloud service APIs, databases, service accounts, and more—and these credentials need to be secure.


Managed or hosted CI/CD pipelines provide a secure way to store these secrets. If you build your CI/CD solution, then you’re in charge of ensuring secrets are stored securely. CI/CD secrets should be encrypted at rest and only decrypted in memory, when the CI/CD pipeline needs to use them.

You should tightly lock down access to the configuration of your CI/CD pipeline. If every engineer can access these secrets, then the potential for leaks is huge. Avoid the temptation to let engineers debug and troubleshoot issues by using CI/CD credentials.

Some secrets (for example, access tokens) need to be refreshed periodically. CI/CD pipelines often use static secrets—which have much longer lifetimes, and so don’t need regular refreshing—to avoid the complexities of refreshing tokens.

Injecting secrets into workloads


Cloud workloads themselves also use secrets and credentials to access other resources and services that their functionality depends on. These secrets can be provided in several ways. If you deploy your system as packages using VM images or containers, then you can bake the secrets directly into the image, making them available in a file when the workload runs.

Another approach is to encrypt the secrets and store them in source control. Then, inject the decryption key into the workload, which can subsequently fetch, decrypt, and use the secrets.

Kubernetes allows for secrets that are managed outside of the workload image but exposed as an environment variable or a file. One benefit of secrets as files is that secret rotation doesn’t require re-deploying the workload.

Infrastructure as code: a security perspective


Infrastructure as code is not only an operational best practice; it is also a security best practice. 

software systems = infrastructure + workloads

When ad hoc changes are made to infrastructure configurations, this drift can introduce security risks. When resources are provisioned without any auditing or governance, it becomes difficult to maintain proper security measures across all resources.

Manage your infrastructure just like you manage your code. Use declarative configurations (like those of  Terraform, AWS CloudFormation, or Kubernetes CRDs). Review and audit every change.

Bring your own security tools


CI/CD pipelines are flexible. Generally speaking, they let you execute a sequence of steps and manage artifacts. The steps themselves are up to you. As a security engineer, you should take advantage of the security tools that already exist in your environment (especially in the cloud). For example, GitHub and GitLab both scan your commits for the presence of secrets or credentials. Some managed CI/CD solutions build in API scanning or application security scans. However, you may also prefer to add tools and checks into the mix.

You could also add static code analysis (like SonarQube) to ensure that code adheres to conventions and best practices. As another example, you mayincorporate vulnerability scanning (like Trivy or Grype) to your CI/CD pipeline, checking container images or third-party dependencies for security flaws.


Comprehensive detection and response


Application observability, monitoring, and alerting are fundamental DevOps Day 2 concerns. Although your CI/CD pipeline is not directly involved in these activities, you should use your CI/CD pipeline to deploy the security tools you use for these purposes. From the point of view of the CI/CD pipeline, these are just additional workloads to be deployed and configured.

Your CI/CD pipeline should include early detection of security issues that trigger on every change that affects workloads or infrastructure. Once changes are deployed, you need to run periodic checks and respond to events that happen post-deployment.

In case of faulty CI/CD, break glass


The CI/CD pipeline is a critical part of your system. If your CI/CD is broken or compromised, your application may continue to run, but you lose the ability to make safe changes. Large scale applications require constant updates and changes. If a security breach occurs, you need to be able to shut down and isolate parts of your application safely.

To do so, your CI/CD pipeline must be highly available and deployed securely. Whenever you need to update, rollback, or redeploy your application, you depend on your CI/CD pipeline.

What should you do if your CI/CD pipeline is broken? Prepare in advance for such a case, determining how your team and system will keep operating (at reduced capacity most likely) until you can fix your CI/CD pipeline. For complicated systems, you should have runbooks. Test how you will operate when the CI/CD is down or compromised.

Cisco Industrial Ethernet, speaking the language

I detailed the robust hardware design of our Industrial Ethernet switches that enables them to withstand harsh environments. In this blog, I will focus on their software features – particularly the support of industrial communications protocols – further cementing the “purpose” in these purpose-built products.

Cisco’s IE (Industrial Ethernet) switches are designed to leverage as much of Cisco’s technology as possible. This includes hardware and software features. Customers expect our software features to behave consistently across product families, including the IE Switching products. Cisco IE switches also run IOS or IOS-XE. There are differences. One difference between Enterprise and Industrial Switching is support for industrial protocols.

What’s a protocol? Protocols define the set of rules by which devices communicate with each other. The internet runs on a protocol referred to an IP. Industrial communications have been using protocols since before IP became as popular as it is today. Every industry seems to have its own set of protocols. Cisco IE switches support a vast majority of these protocols enabling them to be part of any industrial networking solution.

Protocol support is one of many reasons that makes Cisco IE Switching popular

Our Industrial Ethernet (IE) switches are the global market leader in Industrial Ethernet Switching for several reasons:

1. Offer a portfolio of din rail and rack mount of industrialized switching products to fit multiple use cases

2. Have a high quality, built-to-purpose ruggedized hardware design for reliability in industrial deployments

3. Leverage Cisco’s network management and security technologies

4. Support of protocols that enables industrial customers to easily incorporate Cisco’s networking products into their deployments and solutions.

Why support industrial protocols?

In short, because these protocols are vital for the functionality of any modern industrial operation.

Cisco builds network devices to be deployed in a wide variety of industrial networks and solutions. No two industrial networks are alike. There’s a wide variety of requirements and use cases. And there is at least one protocol used in every industrial solution. The networking infrastructure must support all requirements, use cases, and protocols, no matter what they are.

We like to think we don’t have a technology bias. While focusing on our key competency, networking, we will build what customers want to deploy. This applies as well to support of industrial protocols. We are not promoting or supporting one industrial protocol over another. We are not bound to any one technology, solution set, or protocol.

End users, system integrators, and anyone putting together a solution want to use the tools and applications they know and trust and at the same time take advantage of the state-of-the-art networking technology. To enable the tools and applications used in industrial deployments, our IE switches support industrial protocols used to build solutions based on Ethernet networks. Failure to support an industrial protocol often eliminates a networking product as a viable option.

What does support for industrial protocol mean?

Just like the varied industries and protocols, support any one protocol means different things. Protocols differ widely, thus support does too. If you must have a single definition of support, support for an industrial protocol can be equated to ‘speaking the language’. Our IE switches support the communication of industrial protocols enabling end devices to communicate effectively and efficiently.

Cisco Prep, Cisco Learning, Cisco Exam Prep, Cisco Career, Cisco Guide, Cisco Skills
Figure 1: communication flow through the Cisco IE switch

PROFINET and Ethernet/IP CIP are two protocols commonly used by industrial automation and control systems (IACS). Our IE switches are certified compliant to these two protocols by including the software stacks for them. It’s the same software stack as the IACS components. For PROFINET and Ethernet/IP, the Cisco IE switches really do speak the language. Applications using PROFINET or Ethernet/IP can discover and automatically setup Cisco IE switches as a part of the solution, thus avoiding manual procedures.

For other protocols, support may mean recognition. GOOSE is a good example of such a protocol. Our IE switches do not need to support the GOOSE software stack. Protocols such as GOOSE use Layer2 Ethernet or Layer3 Internet protocol. Users can build quality of service policies to prioritize the communication of these protocols. The Cisco IE switch can recognize and prioritize industrial protocol running on standard Ethernet or Internet protocol based messages in the network ensuring end to end quality of service. Regardless of the interaction and support for industrial protocols, Cisco IE switches provide fast, reliable, and secured transport.

What about safety protocols?

Especially safety protocols. Such as PROFIsafe, and CIP Safety.

Support for any protocol implies support for the safety portion of the protocol. Industrial automation (eg: manufacturing) solutions prioritize support for safety protocols. If a protocol has a safety component, then our IE switches support the safety protocol. Most of the time this means recognizing the protocol or the safety messages in the protocol and building a quality-of-service policy to prioritize the communication end to end.

What about Cyber Vision?

Cisco Cyber Vision is an application that runs on Cisco IE switches and uses deep packet inspection to analyze all traffic passing through the switch and identify industrial protocols in use.

Cyber Vision does more than ‘speak the language’. Using its knowledge of industrial protocols, Cyber Vision can identify industrial assets and determine if the payload in these protocols is within operating bounds. It also provides security posture assessments of IACS components.

The application running on our IE switches report a summarized version of its findings to the Cyber Vision center, where end users get a real-time visual representation of all the communications on their operational network.

The figure below is an example of how Cyber Vision enables users to visualize communication between devices. It recognizes which device is speaking which protocol amongst other things.

Cisco Prep, Cisco Learning, Cisco Exam Prep, Cisco Career, Cisco Guide, Cisco Skills
Figure 2: Cybervision visualizes device communication flows

Cyber Vision is a security tool to increase visibility into operational networks. You can’t secure what you can’t see.

Closing

Ultimately, it’s about giving you, the customer, what you want and what you need. You want the latest and greatest technology because you’re investing for the long term. You want quality, which is why you’ve chosen IE switches from Cisco.  You want ease of use. You want to build systems and solutions with the tools you know, trust and which you already have invested in.

Failure to provide any of the above means the customer must compromise. Nobody wants that. With Cisco IE Switching, you don’t have to.

Brief Description of select industrial protocols (with examples)

If you’re new to industrial networking, you can find a brief overview of the main industrial protocols below.

Why so many protocols? Different industries have different protocols they have developed over the years to meet their needs. Most industrial protocols leverage the Internet protocol (IP) for communication. But not always.

What does neuroscience have to do with the Internet?

It’s time for a new approach to the Internet

The Internet has never been so dynamic in more than 40 years of existence. The massive adoption of cloud has paved the way for scores of SaaS applications being hosted “on the Internet.” At the same time, organizations are making hybrid work a part of their strategy moving forward. As a result, employees working from home expect the same level of security and application experience as they have at the enterprise campus. In turn, IT organizations are routing much more of their corporate data across the Internet extending into multiple clouds. And of course, connectivity continues to evolve with traditional link types but also with the rollout of 5G and other new Satellite links.

In such a highly distributed and dynamic environment it becomes extremely hard to keep up by using only traditional and reactive approaches. But just as the complexity of our networking environments is increasing, so also, we can take advantage of recent innovations in cloud, compute, and data aggregation capabilities to improve the Internet.

Reactive measures don’t go far enough

For its entire existence, as a networking industry we’ve pretty much applied the same reactive approach each time an Internet failure occurs. By reactive I mean that we wait until the Internet breaks (path failure) and then reroute traffic along an alternate path (using IGP, MPLS/IP Fast Reroute, etc.). This approach of protection and restoration relies heavily on fast detection of failure followed by rerouting traffic. While a reactive approach is effective and necessary, it’s far less than ideal. The problem is that our processes never learn from any of the previous failures. So, in effect, the same issues could repeat themselves over and over, requiring the same fixes. But consider the possibilities when we tap the power of AI/machine learning and statistical modeling and apply predictive analytics to the Internet to avoid incidents before they occur.

Enabling the Internet with learning capabilities


Surprisingly, we have never enabled the Internet with learning capabilities! A plethora of technologies have been designed and deployed, capable of fast reaction, adapting to changing conditions but without any learning capability (except for quick adaptations after detecting issues such as with TCP windowing, routing convergence, and route dampening to mention a few).

So, what would a learning Internet look like?

Cisco Exam Prep, Cisco Preparation, Cisco Career, Cisco Skills, Cisco Jobs
How many times have you heard people comparing the brain to a computer? And that AI engineers are trying to mimic the human brain? There is too much to cover in a blog but let me share some thoughts. First, the brain is a network of networks and in this way, the Internet shares similarities with it. [Sidenote: stay tuned for a white paper on that subject I will publish with a famous neuroscientist in 2022—Adeel Razi.] Of course, we know that part of what makes us human is cognition and consciousness along with our ability to learn.

Cisco Exam Prep, Cisco Preparation, Cisco Career, Cisco Skills, Cisco Jobs
Second, we learn as our brain builds a model of the world (there are multiple theories on the learning models, with even some poorly understood capabilities of one-shot learning), makes use of sensing (vision, audition, touch, etc.) to adapt and learn, but also perform higher order planning functions in the prefrontal cortex (PFC). What if we enabled the Internet with learning “the same way” our brains learn? The Internet can use models (statistical /machine learning), sensing (telemetry), and self-healing (planning). By enabling the Internet with the ability to learn and predict, we can take preventative actions alongside traditional reactive measures for a more comprehensive approach.

What a predictive Internet would look like


Science fiction? Not at all. Although being able to replicate the brain’s ability to predict is far from being possible with today’s AI technologies, enabling the Internet with the ability to learn is already here.

At Cisco we have been working on the Predictive Internet for over two years, starting with a deep analysis of millions of paths seeking for signals that could be used by an ML/AI engine to learn and predict. And no, there is no magic “algorithm” but rather a plethora of technologies for telemetry processing and training models to then learn and predict. Our Predictive engine is now capable of predicting short- and long-term events thus avoiding issues before they happen. There is no magic there, simply being able to learn and apply more than a decade of ML/AI product developments that perform with very high accuracy, at scale.

Could a Predictive engine predict all issues? Not at all …. but the engine has been tuned to predict as many events as possible with extremely high accuracy. More soon …

Application-centric Security Management for Nexus Dashboard Orchestrator (NDO)

Cisco Nexus Dashboard Orchestrator (NDO), Cisco Exam Prep, Cisco Tutorial and Materials, Cisco Career, Cisco Prep, Cisco Preparation, Cisco Guides

Nexus Dashboard Orchestrator (NDO) users can achieve policy-driven Application-centric Security Management (ASM) with AlgoSec

Cisco Nexus Dashboard Orchestrator (NDO), Cisco Exam Prep, Cisco Tutorial and Materials, Cisco Career, Cisco Prep, Cisco Preparation, Cisco Guides
AlgoSec ASM A32 is AlgoSec’s latest release to feature a major technology integration, built upon a well-established collaboration with Cisco — bringing this partnership to the front of the Cisco innovation cycle with support for Cisco Nexus Dashboard Orchestrator (NDO) allows Cisco ACI – and legacy-style Data Center Network Management – to operate at scale in a global context, across data center and cloud regions. The AlgoSec solution with NDO brings the power of intelligent automation and software-defined security features for ACI, including planning, change management, and micro-segmentation, to global scope. There are multiple use cases, enabling application-centric operation and micro-segmentation, and delivering integrated security operations workflows. AlgoSec now brings support for EPG and Inter-Site Contracts with NDO, boosting their existing ACI integration.

Let’s Change the World by Intent

Since its 2014 introduction, Cisco ACI has changed the landscape of data center networking by introducing an intent-based approach, over earlier configuration-centric architecture models. This opened the way for accelerated movement by enterprise data centers to meet their requirements for internal cloud deployments, new DevOps and serverless application models, and the extension of these to public clouds for hybrid operation – all within a single networking technology that uses familiar switching elements. Two new, software-defined artifacts make this possible in ACI: End-Point Groups (EPG) and Contracts – individual rules that define characteristics and behavior for an allowed network connection.

ACI Is Great, NDO Is Global

That’s really where NDO comes into the picture. By now, we have an ACI-driven data center networking infrastructure, with management redundancy for the availability of applications and preserving their intent characteristics. Using an infrastructure built on EPGs and contracts, we can reach from the mobile and desktop to the datacenter and the cloud. This means our next barrier is the sharing of intent-based objects and management operations, beyond the confines of a single data center. We want to do this without clustering types, that depend on the availability risk of individual controllers, and hit other limits for availability and oversight.

Instead of labor-intensive and error-prone duplication of data center networks and security in different regions, and for different zones of cloud operation, NDO introduces “stretched” EPGs, and inter-site contracts, for application-centric and intent-based, secure traffic which is agnostic to global topologies – wherever your users and applications need to be.

Having added NDO capability to the formidable, shared platform of AlgoSec and Cisco ACI, region-wide and global policy operations can be executed in confidence with intelligent automation. AlgoSec makes it possible to plan for operations of the Cisco NDO scope of connected fabrics to be application-centric and enables unlocking the ACI super-powers for micro-segmentation. This enables a shared model between networking and security teams for zero-trust and defense-in-depth, with accelerated, global-scope, secure application changes at the speed of business demand — within minutes, rather than days or weeks.

Key Use Cases

Change management — For security policy change management this means that workloads may be securely re-located from on-premises to public cloud, under a single and uniform network model and change-management framework — ensuring consistency across multiple clouds and hybrid environments.

Visibility — With an NDO-enabled ACI networking infrastructure and AlgoSec’s ASM, all connectivity can be visualized at multiple levels of detail, across an entire multi-vendor, multi-cloud network. This means that individual security risks can be directly correlated to the assets that are impacted, and a full understanding of the impact by security controls on an application’s availability.

Risk and Compliance — It’s possible across all the NDO connected fabrics to identify risk on-premises and through the connected ACI cloud networks, including additional cloud-provider security controls. The AlgoSec solution makes this a self-documenting system for NDO, with detailed reporting and an audit trail of network security changes, related to original business and application requests. This means that you can generate automated compliance reports, supporting a wide range of global regulations, and your own, self-tailored policies.

The Road Ahead

Cisco NDO is a major technology innovation and AlgoSec and Cisco are delighted and enthusiastic about our early adoption customers. Based on early reports with our Cisco partners, needs will arise for more automation, which would include the “zero-touch” push for policy changes – committing EPG and Inter-site Contract changes to the orchestrator, as we currently do for ACI and APIC. Feedback will also shape a need for automation playbooks and workflows that are most useful in the NDO context, and that we can realize with a full committable policy by the ASM Firewall Analyzer.
