Why Organizations With Sensitive Research or Intellectual Property Need a Zero Trust Cybersecurity Framework Approach

The emergence of Zero Trust has shifted the center focus of some security frameworks from securing the perimeter to protecting sensitive data. While both are extremely important, this shift to a sensitive data-centric framework has advantages. To further understand the benefits of Zero Trust, consider a few specific scenarios:

◈ A large university that does over $100M in Federal Research

◈ Any company with intellectual property or in the process of acquiring or selling off organizations

◈ A state, county, or large city that needs to protect their Criminal Justics Information Services (CJIS) data

◈ Industrial Controls Systems (ICS); power, water, roads, or buildings.

◈ Election infrastructure security

Using those above situations, let’s start with the basics that you need to understand:

◈ Who is after your sensitive information:

     ◈ Where does it sit?

     ◈ What are the capabilities of the bad actors?

     ◈ What are the three biggest gaps that you need to address asap?

◈ Do you have an accurate inventory of your hardware?   Can’t protect what you do not know about…

◈ Inventory of your software and their application flows?  Most moves to cloud fail due to lack of insight related to dependencies.

◈ What are your key risks (threats, brand image, fines, and compliance).

◈ Understand what your top 50 pieces of sensitive data are.  Rarely does anyone do full data classification.

◈ Understand where your top 50 pieces of sensitive data presently reside.

◈ What are your organiazations capabilities around Segmentation, Priviledge Escalation Monitoring, and Multi Factor Authentication?

◈ Can you spot priviledge escalaton (user and application processes) ?

◈ How well are your security solutions integrated? Automated? Use the same intelligence?

Then analyze where you are with the necessary people, process, and technology basics. Most organizations should leverage the resources and technologies that they already have and understand where the gaps are, so they can address them over the next one to three years.   Cisco Advanced Security Services can help you with this analysis, strategy, implementation analysis, design, pilot, and implementation work.

Go to a workshop with Cisco Advanced Services, so you understand what the gaps are, how to best address them, and prioritize your work.  This end-to-end approach will help you address your key use cases to get the outcomes you need addressed.

Moving Towards The Zero Trust Cybersecurity Framework?

The first step should be an investigation and analysis of what your sensitive data is, where it lives, and who accesses it. Then analyze the three Foundational Pillars (see below) to see where you are with the necessary people, process, and technology basics. Most organizations should leverage the resources and technologies they already have in place, and understand where the gaps are so they can address them over the next one to three years. Cisco Advanced Security Services can help you with this analysis, strategy, and implementation work.

The three foundational Pillars are:

1. Zero Trust Platform
2. Security Automation and Orchestration
3. Security Visibility and Analytics

These Zero Trust Foundational Pillars work great whether you leverage the CIS 20, NIST 800, or the ISO 27000 family cybersecurity frameworks. A few key things you need for all of them include:

◈ Segmentation, Priviledge Escalation Monitoring, and Multi Factor Authentication
◈ Inventory of your hardware and software plus application flows
◈ What are your key risks (threats, brand image, fines, and compliance)
◈ Understand what your top 50 pieces of sensitive data are
◈ Understand where your top 50 pieces of sensitive data presently resides
◈ Who is after this information?   What are their capabilities

A quick high level overview of the 3 foundataional pillars based on the information from Forrester Research: :

1. Zero Trust Platform
• Data security, which is ultimately a technology solution
• Managing the data, categorizing and developing data classification schemas, and encrypting data both at rest and in transit
2. Security Automation, Orchestration Security, and Risk leadership to leverage and use tools and technologies that enable automation and orchestration across the enterprise.
• The ability to have positive command and control of the many components that are used as part of the Zero Trust strategy.
3. Security Visibility and Analytics
• You can’t combat a threat you can’t see or understand. Tools such as traditional security information management (SIM), more-advanced security analytics platforms, security user behavior analytics (SUBA), and other analytics systems enable security professionals to know and comprehend what’s taking place in the network.
• This focus area of the extended Zero Trust ecosystem helps with the ability of a tool, platform, or system to empower the security analyst to accurately observe threats that are present and orient defenses more intelligently.

Do a workshop with Cisco Advanced Services so you understand what the gaps are, how to best address them, and prioritize your work.  This end to end approach will help you address your key use cases to get the outcomes you need addressed.

Be sure to take into consideration the Core principles that make up Zero Trust:

1. Identify and Catalog your Sensitive Data
2. Map the data flows of your sensitive data
3. Architect your Zero Trust network
4. Create your automated rule base
5. Continuously monitor your trusted ecosystem

How Antifragile Systems of Trust Can Strengthen Blockchain Initiatives

What doesn’t kill us makes us stronger. We resist gravity, and our muscles become stronger. We negotiate conflicts, and our emotional intelligence increases. But what if this also applied to IT systems? The next generation of networked systems could autonomously improve themselves as outside forces threaten them.

I and the rest of the Cisco Innovation team already believe blockchain is going to play an important role in securing data, but blockchain could also help entire networks learn to better protect themselves and intervene more quickly.

“Antifragility is beyond resilience or robustness. The resilient resists shocks and stays the same; the antifragile gets better. … The antifragile loves randomness and uncertainty, which also means — crucially — a love of errors, a certain class of errors. Antifragility has a singular property of allowing us to deal with the unknown, to do things without understanding them — and do them well. Let me be more aggressive: We are largely better at doing than we are at thinking, thanks to antifragility. I’d rather be dumb and antifragile than extremely smart and fragile, any time.”

We could take a lesson from this idea to design decentralized antifragile systems — whether they are business networks, applications or infrastructure — that become stronger the more people or machines try to break them. Blockchain technology offers specific advantages that all enterprise networks require — one single version of the truth, data immutability and automated processes among them. Combining blockchain technology with machine learning algorithms would allow multi-stakeholder systems to continually improve themselves, better react to challenges in the future and perhaps even anticipate potential problems.

I wrote an article last year about FCAPS, blockchain and trust that is relevant here. Anyone who works in telecommunications is at least tangentially familiar with the ISO/OSI and ITU network management models that shape our processes for fault, configuration, account, performance and security management — FCAPS.

My theory is that setting up machine learning algorithms to constantly measure specific parameters and adjust themselves accordingly could allow those systems to learn new solutions to preserve their operation levels. You would break systems of trust down into key components and use tight feedback loops to record and respond to specific parameters. Those tightly defined parameters could evolve over time. In a multi-stakeholder ecosystem, each stakeholder would extend insights to the collective. So in essence, there is no one system of trust but a series of trusted domains, each independently serving a specific, special function.

Let’s say your system is designed to move data from one point to another point with some certain level of efficiency. Then a configuration change happens — perhaps it’s a simple user error or a malicious configuration change. The system could learn from that instance so that the next time such a change happens, the system can automatically correct it or alert an admin to the issue that would cause it to move out of spec. Now imagine these changes as a collection of events across multiple enterprise domains.

Extremely few environments today have only one vendor as the source of their technology. Just one data center will have multiple vendors involved, and you have to be sure that this heterogeneous system runs efficiently across all providers. Let’s say your business application spans multiple clouds — how do you ensure your product delivers the quality your customers expect if something happens to one of your service providers?

Some of these issues can be learned and prevented in the future to create more robust, responsive systems. This article proposing a manifesto for antifragile software from the University of Bologna is also interesting. Inspired by the Agile Manifesto, the researchers have laid out a common framework for making software that is antifragile; the principles could also be applied to making antifragile networks. The Antifragile Software Manifesto is all about building networks of trust and continuous improvement. Here are some highlights:

◈ Our highest priority is to satisfy the customer by building a non-linear, proactive, and self-adaptive system.
◈ All stakeholders, and the broader environment, lead the antifragile organization.
◈ Continuous exposure to faults and automatic fixing is the primary measure.
◈ An antifragile organization promotes a context aware environment. The stakeholders should be able to maintain a system indefinitely.

Sounds like enterprise blockchain, right? We are striving to create networks that are decentralized and self-adapting, with many stakeholders and built-in redundancy, where all participants have skin in the game but no one actor can sabotage it. Adding machine-learning algorithms that constantly improve these enterprise blockchain networks will even better protect the data and stakeholders involved.

For our enterprise clients, confidence and privacy of data are understandably very important matters. Sustaining these states can be accomplished using selective disclosure. You define who gets to see what information as you write data to a blockchain network. Policies should be set up in the network so data being posted is always compliant with the governance models all parties have agreed upon. Your users’ roles and responsibilities within the network will grant them the according degrees of access to information. So an auditor could be granted access to all information, but a data entry specialist would have only access to certain areas.

The next level would be creating a data overlay specifically for the purpose of providing algorithms access to ecosystem-attested data — data that is compliant, shared correctly and of high value. In theory, machine-learning algorithms may produce higher quality insights for antifragility as ecosystem-wide observations are shared. Infrastructure is a perfect example of a complicated system with many stakeholders and massive amounts of high-quality data for a machine-learning algorithm to munch on. Putting the blockchain in between infrastructure and machine learning would potentially give us the ability to increase quality for all users while maintaining control of data access and preventing tampering.

The Five Focus Areas for 5G Security Innovation and Thought Leadership

5G brings the promise of new revenue opportunities for service providers. Service providers will be able to offer new differentiated services and capabilities, connecting customers to multi-cloud services and applications with specific KPIs.

To help service providers in the delivery of 5G, Cisco’s Cloud-to-Client approach unifies multi-vendor solutions into a single, standards-based architecture and spans across multi-cloud, IP routing, 5G core, service edge, access networks, Internet of Things (IoT), and security.

New revenue opportunities are infinite, so are security threats. Many IoT services will utilize new 5G air interfaces. Networks will be more distributed leading to a surge in entry points for more destructive threats, and new transient or moving threat boundaries.

To prepare service providers for these looming security challenges, Cisco offers a comprehensive security approach for the optimal deployment and consumption of 5G services, revealed in detail in our 5G security innovation with Cisco white paper.

5G Security Risks

5G will increase in wireless capacity by 1,000 times and connect 7 billion people and 7 trillion “things”, estimates a joint initiative between EU Commission and European ICT.

This massive throughput connectivity and capabilities in 5G require a major network architectural change, from radio access to the core. It bridges wireless and wireline networks through an evolving architecture which can involve network slicing, Control and User Plane Separation (CUPS), Mobile Edge Computing (MEC), just to name a few of the changes to the network. As the network changes at the same time, new challenges and threats will come about.

As we move into the 5G era we are also seeing more sophisticated attacks. Gartner believes half of the malware next year will use some encryption to hide malware and organizations today do not have a solution for this.

In my view, 5G’s evolving architectural nature and an expanding threat surface call for an integrated end-to-end approach to cybersecurity. Our security innovations based on visibility (even in encrypted traffic) and control for the entire 5G network, up to all applications, can provide a secure delivery of new cases with service assurance.

Intrinsic Security is Key

In the world of 5G, traditional siloed security and add-on edge appliances have limitations, are complicated and costly. Security today does not interoperate enough with the network and there will be gaps if we follow the same approach with 5G.

Cisco’s security innovation is holistic and intrinsic to the network. Leveraging the network functions themselves for visibility and fast threat identification, segmentation to reduce the attack surface and the impact of an attack; threat protection to stop a breach across multiple points of the network; and support from our threat intelligence Talos team.

5G Security Innovation with Cisco

5G security needs an integrated approach to deal with close to 20 billion threats per day. With visibility and control from end-to-end, Cisco’s full suite of 5G solutions and end-to-end security architecture can help service providers in the Asia-Pacific region stop threats at the edge, protect users wherever they work, control who gets on the network, simplify network segmentation, and find and contain problems fast.

Containers in Production: Accelerate the Learning Curve

There is a learning curve associated with scheduling containers in production on Kubernetes. But if your cloud architect or platform engineering team can integrate and configure the set of tools needed for deploying and managing containerized workloads, then Developers, Application Ops, and Cluster Ops teams can move up the curve and accelerate time to value for your business.

But before we discuss how one can move up the learning curve, let’s first get a little context on why containers are a forcing function for change.

Historical Context

When virtual machines (VMs) were new, the technology learning curve primarily affected Ops teams who had to learn about the management, snapshotting, and migration of this new abstraction. The primary unit of management was the VM, not the physical server. Development practices didn’t change much in order to get the most value out of the technology.

But the transition to containerized workloads, as well as the deployment of containers in production on Kubernetes, have a big impact on both Dev and Ops. Containers change how applications are architected and written, and also change how applications are managed, monitored, and supported in production.

So, now both Dev and Ops have a new technology learning curve.

Developers Learning Curve

Rewriting your application for containers is not as simple as taking an application running on a physical machine or a virtual machine and just packaging it in a container. Rather, developers need to do some things differently with containers. This includes:

◈ Packaging – consider packaging with build instructions stacked in layers.
◈ Service discovery and catalog – since you’ll be running services across multiple containers, find and bind to dependent services.
◈ Key management – managing authentication and rotate keys across services.
◈ Logging and monitoring – obtaining data about the application, container, and node levels, as well as dependent services.

Ops Learning Curve

Ops arguably has an even bigger learning curve. Virtual Machines introduced a lot of dynamic things within an infrastructure environment, but containers make an order of magnitude worse because now you can spin up workloads within milliseconds, kill it, and start it somewhere else. This learning curve involves:

◈ Compute capacity planning – planning CPU and memory at a different level that includes multiple containers on a single machine (physical or virtual).

◈ Networking –. managing networking within and between Kubernetes clusters, especially since more containers means more east-west network traffic. These clusters may include both private infrastructure and public cloud.

◈ Persistent Storage – requires higher service levels than ephemeral applications.

◈ Logging and monitoring – there are usually more containers than an equivalent number of VMs for a monolithic application. And they may move if Kubernetes health check replicates pods on a different host.

◈ Data – a VM or virtual disk might include 10 different containers, so you need to shift thinking about snapshotting data at a container level.

◈ Namespaces – coding to namespaces as a variable, or mapping and managing namespaces across your various environments.

◈ Tracking changes – IT remaining responsible for Service Levels and tracking the history of simple changes. This is especially crucial with the ephemeral nature of containers and Kubernetes’ replication across nodes.

Overall, many of the Dev and Ops tools and processes that were optimized for VMs, now need to be updated and re-optimized for containers.

Don’t Get Bogged Down in the Stack

To make this work, you will likely need someone assigned to an AppOps role that works in production to support containerized applications. Also, you’ll likely need a specialized IT Ops role, call it ClusterOps, to manage Kubernetes and field requests for namespace resources or cluster lifecycle management.

But if you run Kubernetes on premises as part of a hybrid cloud solution, you’ll also need a cloud archteicture or platform engineering role to build the Kubernetes tool stack and connect to and secure the cloud. They can deploy and integrate all the tools needed to lifecycle manage your Kubernetes clusters, including underlying compute, network, and storage on private infrastructure.

Building and maintaining this type of integrated on and off-premises solution takes work — both upfront systems integration and configuration work, and the ongoing management and testing of individual tools and platforms through their upgrade cycles.

If all the tools you need to deploy containerized workloads on premises or in the cloud are integrated and tested working together such as the Cisco Hybrid Cloud Platform for Google Cloud – then it will be faster and easier for developers, as well as Application Ops and Cluster Ops counterparts, to move up the learning curve and accelerate time to value for your business.

Promote Cloud Adoption in Education without Exposing Students to Risk

Cloud based collaboration is being adopted rapidly by organizations in all verticals, and education is no exception. Access to collaborative tools can’t be as simple as an on/off switch. School administrators need visibility to prevent the loss of sensitive data and to ensure that students aren’t engaging in inappropriate communication. On-premise policies must be equally enforced as students leverage cloud-based tools.

Allowing Only the Correct External Communications

Schools are quick to welcome collaborative platforms like Google Drive, Microsoft’s Office 365, and Dropbox. Cloudlock, an important piece of the Cisco Security portfolio, enables educators to enforce policies across these platforms to ensure that only the appropriate personnel are logging in. Cloudlock can detect logins from questionable locations and report on multiple failed logins to applications.

Umbrella, a cloud-based extra layer of security, can recognize requests made from an organization to dangerous domains. Policies can block security categories like malware, cryptomining, and command and control. Behavior policies can be leverage to prevent requests to inappropriate sites like gambling, alcohol, and adult themes.

Addressing Behaviors and Communications

Once students and personnel log in, policies can be enabled and enforced around communication. These pre-defined policies include categories like aggressive behavior, discrimination and cyberbullying. If students are engaging in these behaviors on collaboration platforms, administrators can be warned about incidents that violate these policies.

Additionally, pre-defined policies include language associated with self-harm, which would be present in shows like Netflix’s TV series 13 Reasons Why. School systems reacted to this show in varying ways including banning it, recommending that parents watch it with their children, and providing lists of resources designed to identify depression. The self-harm template provides an additional degree of visibility for educators and counselors into students’ interactions.

Protecting Access to Data for Compliance

School systems have compliance requirements also. One example is data included under the Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232g; 34 CFR Part 99). This data is related to the transfer of students and access to it is restricted to the school systems involved, accrediting organizations and judicial parties overseeing these cases. Cloudlock contains templates that look for the sensitive “directory” information.

Finally, educational organizations look to ensure that only sanctioned cloud-based applications are installed and used on devices. Umbrella provides a cloud services report to identify applications that are requesting access to cloud services. This report can provide visibility into unsanctioned applications, allowing admins to restrict access to only applications sanctioned by the organization.
