Quantum Security and Networking are Emerging as Lifelines in Our Quantum-powered Future

A metamorphosis continues to take shape with the rise of Post-Quantum Cryptography, Quantum Key Distribution, and the brave new world of Quantum Networking.

In the ever-evolving landscape of technology, quantum computing stands out as a beacon of both promise and challenge. As we delve into the world of quantum networking and security, we find ourselves at the intersection of groundbreaking innovation and urgent necessity.

Cisco believes that quantum networking is not just an intriguing concept. It drives our research and investment strategy around quantum computing. We see it as a critical path forward because it holds the key to horizontally scaling systems, including quantum computing systems. Imagine a future where quantum computers collaborate seamlessly across vast distances, solving complex problems that were previously insurmountable.

However, before we can realize the promise of quantum networking, we need to address the elephant in the room – security. When quantum computers become reality, our classical cryptographic methods will face an existential threat. These powerful machines will potentially break today’s encryption algorithms in seconds. Our digital fortresses are vulnerable.

This opens the question of what will happen when quantum computers enter the scene. The issue lies in key exchanges. In classical systems, we rely on public key infrastructure (PKI) to securely exchange keys. This has served us well, ensuring confidentiality and integrity. But quantum computers, with their uncanny ability to factor large numbers efficiently, disrupt this equilibrium. Suddenly, our once-secure secrets hang in the balance.

Getting to the heart of the matter, imagine a scenario that persists even in our current era – the ominous concept of “store now, decrypt later”. Picture an adversary intercepting encrypted data today. Biding their time, they await the moment when quantum supremacy becomes reality.

When that day dawns, they unleash their quantum beast upon the stored information. Our sensitive communications, financial transactions, and personal data will suddenly be laid bare, retroactively vulnerable to the quantum onslaught.

Post-Quantum Cryptography is gaining momentum

Enter Post-Quantum Cryptography (PQC). Recognizing the urgency of the coming quantum moment, the National Institute of Standards and Technology (NIST) has been evaluating PQC proposals and is expected to release its final standards for quantum-resistant cryptographic algorithms later this year. These algorithms are designed to withstand quantum attacks and while not perfect, they are intended to fill the gap until quantum-safe solutions mature.

Apple’s iMessage is a compelling proof point. Last year, Apple made a decisive move by announcing its adoption of PQC algorithms for end-to-end encryption. This strategic shift underscores the industry’s recognition of the looming quantum threat, especially around “store now, decrypt later” attacks, and the need to swiftly respond.

In the year ahead, as we move closer to the post-quantum world, PQC will continue to gain momentum as a data security solution. Cisco’s Liz Centoni shared insight in her tech predictions for 2024, highlighting the accelerating adoption of PQC as a software-based approach that works with conventional systems to protect data from future quantum attacks.

PQC will be used by browsers, operating systems, and libraries, and innovators will experiment with integrating it into protocols such as SSL/TLS 1.3, which governs classic cryptography. PQC will likely find its way into enterprises of every size and sector as they seek to safeguard their sensitive data from the threats posed by quantum computers.

Quantum Key Distribution is the holy grail

Beyond PQC lies the holy grail of quantum cryptography, which is Quantum Key Distribution (QKD). Last year, we accurately predicted that QKD would become more widely used, particularly within cloud computing, data centers, autonomous vehicles, and consumer devices like smartphones.

Unlike classical key exchange methods, QKD capitalizes on the no-cloning property inherent in quantum states whereby information encoded on one qubit cannot be copied or duplicated to another because quantum states are fragile, affected by any and every action such as measuring the state. In practical terms, that means an eavesdropper can always be discovered due to a “read” causing the photon state to change.

Consider a scenario where two parties, Bank A and Bank B, want to communicate securely. They use QKD, where Bank A sends quantum states (like polarized photons) to Bank B which measures them without knowing the original state.

The measurements are then used to create a shared key, based on a randomly selected subset of the transmitted state (measurement bases) reconciled between the two parties through an authenticated and encrypted classical channel. Since the eavesdropper does not know the random subset, any attempt to measure the transmitted information will be detected due to a disturbance in the quantum states.

The beauty lies in the provably secure nature of QKD — quantum mechanics forbids perfect cloning, rendering interception futile. In this dance of particles and principles, QKD stands as a lighthouse of security, promising a future where quantum and classical work in tandem to safeguard us.

For instance, integrating QKD in 5G communication infrastructure is becoming increasingly important. With QKD, organizations will be able to better protect the privacy and authenticity of data transmitted over low-latency, high-speed networks, explicitly addressing the security demands of the 5G era.

Efforts to make QKD solutions more accessible and interoperable are accelerating in response to the demand for even more secure data transfer. This is leading to commercialization and standardization initiatives that are expected to make QKD solutions more user friendly and cost effective, ultimately driving widespread adoption across new applications and sectors.

As strides continue toward achieving quantum-secure messaging, among the first organizations to more broadly implement PQC will likely be those responsible for critical infrastructure and essential government suppliers. Large enterprises and other organizations will follow, also implementing these algorithms within the next few years.

Quantum networking on the horizon

Depending on the desired level of security and performance required, Centoni explained that QKD can be used as either an alternative or a complement to PQC and, in the future, will also leverage quantum networking. However, she acknowledges that it’s early days for quantum networks.

So far, researchers have not successfully achieved sustained quantum networking on a large scale, but major discoveries and advancements are happening. Companies like Cisco, alongside cutting-edge leaders across various industries, are pouring billions into unlocking the awesome potential of quantum networks.

“Quantum networking will see significant new research and investment by government and financial services,” said Centoni. She predicts that this will also include sectors with high demand for data security and the kinds of workloads that perform well with quantum computers.

Quantum networking relies on teleportation principles of quantum mechanics to transmit information between two or more quantum computers. This takes place by manipulating qubits whereby they “entangle” with one another and enable instantaneous transfer of quantum information across vast distances – even when there’s no physical connection between the computers.

In the not-so-distant future, perhaps 4 to 5 years or more, quantum networking will inexorably emerge as a potent force. With quantum networking, quantum computers will be able to collaborate and exchange information to tackle intricate problems that no single quantum computer could solve on its own.

By leveraging the quantum principles of teleportation and non-cloning, quantum networking protocols will facilitate fast, reliable – and perhaps even unconditional – secure information exchange. Potential applications of quantum networking go far beyond cryptography, as well, to turbocharging drug discovery, artificial intelligence (AI), and materials science.

Looking to the post-quantum future

Today, quantum computers are at a very similar stage that mainframes were in the 1960s. Back then, very few organizations could afford those machines, which could fill an entire room. While QKD is now in use as a means of provably secure communication, quantum networking remains mainly theoretical.

QKD is the next generation of quantum cryptography, a step beyond PQC which is not provably secure because of the lack of a proof of mathematical hardness for the cryptographic algorithms. Quantum networking should be thought of as first, a substrate needed for QKD, and then building out larger and larger compute islands – such as data centers and LAN, then WAN – analogous to how classical computers were connected to build distributed computing.

The big challenge now, like the past, is to create quantum computers that can be both reliably and affordably scaled up and put into the hands of corporate, government, and research entities. As such, distributed quantum computing will be the primary driver for quantum networks. We may even see the advent of the quantum cloud and the quantum internet – the metamorphic network of the future.

Quantum networking and security are not mere buzzwords. They are our lifelines in a quantum-powered future. As we race against time, we must embrace quantum technologies while fortifying our defenses. The ultimate payoff is a network that’s more secure than anything we’ve known before — a network where quantum and classical dance harmoniously, protecting our digital existence.

Balancing agility and predictability to achieve major engineering breakthroughs

I shared the progress we’re making toward building the Cisco Security Cloud, an open, integrated security platform capable of tackling the rigors of securing highly distributed, multicloud environments. This was an honest assessment of what we have achieved and celebrating our significant accomplishments, moving the needle forward on our vision. I want to share how we approach our research, development, execution and what are our core principles to driving innovation at scale.

In any large organization with a diverse enterprise-grade portfolio varying in adoption levels, solution longevity, and product category maturity, you will find the need to continuously look for ways and means to drive efficiency and excellence. We are fortunate to have loyal customers who trust that with Cisco, they can both secure and manage risk to their organization. Our focus has been to meet customers where they are, and that involves delivering security solutions in various form factors and platforms for a hybrid, multi-cloud world.

To do this, we are evolving our engineering organization to deliver on ambitious goals through higher levels of agility. Agility requires the courage to break down organizational silos and embrace the notion of failing fast and learning even faster from those failures. But engineering organizations like ours also have our “day jobs” with the reality that constantly changing customer and business environments can wreak havoc on engineering roadmaps. This leads to the inevitable difficult decision on whether to focus on the backlog of customer-requested features, versus delivering new, innovative features that move the industry forward.

Another way to say this is that as much as engineering organizations strive for agility, we have to be cognizant of how much our customers crave predictability in terms of their security operations and  feature delivery from vendors like Cisco. Let’s look at this from the lens of a customer-impacting factor that may make security operations less predictable: security incidents.

• According to our 2024 Cybersecurity Readiness Index, 54% of organizations said they have experienced a cybersecurity incident in the last 12 months.
• The latest Security Outcomes Report shows preventing incidents and mitigating losses are the top priorities for security resilience overall.

These numbers are meaningful because cybersecurity is a critical part of any business and part of business resilience plans, which can involve public disclosures. Cybersecurity is also in the line of critical operations functions and can be a cause of major disruptions for the entire business when it fails. So, that is the high-stakes nature of the balancing act we have in front of us with one end of the see-saw being our desire to achieve agility with the other end being our responsibility to our customers to be predictable in their security operations, which are becoming ever more critical in the viability of their businesses.

A pragmatic approach to balancing agility and predictability

Leading a large engineering organization in charge of one of the broadest security product portfolios has challenged me to think about this critically. There are many ways to balance agility and predictability, but we’ve been able to distill this down to a pragmatic approach that I believe works best for us.

Careful short and long-term planning.

This is a critical step that provides the framework for building an engineering org that is both agile and predictable. It starts with iterative planning that allows for reviewing and adjusting plans based on market feedback and changing conditions. This includes meeting shorter-term commitments and regular updates to maintain customer confidence while allowing for adjustments. We also use agile retrospectives and adaptive planning to ensure forward progress and our ability to incrementally improve.

Resource allocation and ruthless prioritization play a key role. We achieve this through segmentation and portfolio management, segmenting a product portfolio into different categories based on levels of predictability and innovation. We exercise scenario planning for risk mitigation and management, developing scenarios that explore different market conditions with strategies for responding to ensure we make informed decisions in uncertain conditions. This helps us identify and mitigate risks that may impact our agility and predictability, account for potential disruptions, prioritize appropriately, and manage expectations.

Clear and consistent communication.

One of the most important aspects of this is the need for clear and consistent communication. As leader, it is my responsibility to clearly articulate the benefits of agility and explain the steps we need to take to ensure the predictability and delivery needed for stable operations. My philosophy is that shared outcomes involve “shared code” that results in a platform-centric development approach and an inner source execution model that allow for acceleration of feature development and delivery velocity.

An org culture willing to adapt.

Even the best of plans will fail without capable people who can and are willing to execute on them. For us, this involves an on-going evolution across our large, highly distributed engineering organization to foster a culture that values both agility and predictability and aligned with one of Cisco’s core values: accountability. A few of the ways we’ve seen success are by:

• Encouraging cross-functional collaboration and open dialogue about the challenges and benefits of both approaches.
• Ensuring leadership is aligned with the organization’s approach to balancing agility and predictability.
• Creating opportunities, like Hackathons, to fail fast and learn even faster, explore the art of the possible, and to dive into technology to solve unexpected challenges.
• Ensuring consistent messaging and support for team members.

Effective processes, not bureaucracies.

Processes often get a bad rap because they are often associated with bureaucracies that can hinder speed and progress. But processes are critical to make sure we’re executing our plans in the intended ways with the ability to measure progress and adapt as necessary. In our goal to balance agility with predictability, we have implemented some specific aspects to processes that work best for us.

• We blend agile methodologies with more traditional project management approaches (e.g., agile for new features, waterfall for foundational infrastructure). Our processes allow us to take a “dual plane” approach to innovation with one plane focusing on predictable, stable delivery while the other explores innovative, experimental initiatives.
• As the aphorism goes, “you can’t manage what you can’t measure”. We have implemented an outcome-focused approach toward metrics that shifts the focus from output (deliverables) to outcomes (business value). This allows us to demonstrate how agility enhances the ability to deliver value quickly and adapt to market changes, solving some of the toughest challenges for our customers.
• We take a customer-centric approach in all things we do. This means we use customer feedback and market insights to prioritize and guide innovation efforts. This includes dedicated customer advisory boards, and programs built around the voice of our customers like NPS surveys. This helps ensure that agility is directed toward meeting customer needs and not innovating for innovation’s sake.

Our processes involve adaptive governance and continuous learning that accommodates both agility and predictability. This includes providing guidelines for making decisions in dynamic situations, continuously assessing what’s working and what’s not, and encouraging a learning mindset and adjusting strategies accordingly.

Innovating to win

Taking a customer centric approach to all things we do, we’ll continue focusing on the breakthrough successes that showcase our ability to be both agile and predictable to meet market demands and deliver customer outcomes. One example of this is how we, as the official cybersecurity partner of the NFL, helped secure this year’s Super Bowl that was the most watched telecast in this game’s history. We also continue our incredible work with AI and Generative AI like the Cisco AI Assistant for Security to simplify policy, and AI-enabled security operations through innovation for both AI for security and security for AI. When we strike the balance of agility and predictability, we innovate to win.

Pave the Way for New Revenue with Transport Slicing Automation and Assurance

Excellence in service matters. Whether you are a mom-and-pop operation or a multibillion-dollar business spanning multiple industries, keeping customers happy and satisfied is essential. No one knows this better than telecommunication (telecom) providers—who experience close to 40% customer churn due to network quality issues, according to McKinsey.

For telecom providers, delivering an outstanding digital experience means smarter troubleshooting, better problem-solving, and a faster route to market for innovative and differentiated services. As if delighting customers and generating new revenue weren’t enough, there is also the added pressure of keeping operational costs low.

For operators of mass-scale networks, that can be a tall order. The good news is that innovative solutions like transport slicing and automated assurance are creating opportunities for service providers to build new revenue streams and differentiate services on quality of experience (QoE) with competitive service-level agreements (SLAs). In this blog post, we will explore how transport slicing and automated assurance can revolutionize the network landscape and transform service delivery, paving the way for financial growth.

Simplify and transform service delivery

Despite ongoing transformation efforts, telecom and high-performance enterprise networks are becoming increasingly complex and challenging to manage. Operations for multivendor networks can be even more complicated, with their various domains, multiple layers of the OSI stack, numerous cloud services, and commitment to end-to-end service delivery.

Complexity also impacts service performance visibility and how quickly you can find, troubleshoot, and fix issues before customer QoE is impacted. To understand the customer experience and differentiate services with competitive enterprise SLAs, you need real-time, KPI-level insights into network connections across domains and end-to-end service visibility. To confront these challenges, many service providers have been attempting to simplify network operations while reducing the cost of service delivery and assurance.

So, how do you streamline increasingly busy transport network operations? For one, advanced automation and orchestration tools can automate intent-based service provisioning, continuously monitor SLAs, and take corrective action to maintain service intent. Automated assurance, for example, can proactively monitor service performance, as well as predict and remediate issues before customers are impacted. This reduces manual work and allows for quicker reaction times to events that impact service.

With leading-edge platform and automation capabilities, you can deliver a wide range of use cases with a unified interface for visualization and control to manage network services effectively. This makes complex multidomain transport networks more accessible and easier to operate, which can help improve capital efficiency, enhance OpEx utilization, and accelerate new service launches.

The operational agility created by simplifying network operations allows you to adapt quickly to market changes and customer needs. You can assure services while securing new revenue streams and capitalizing on emerging service delivery opportunities.

Leverage transport slicing for the best outcomes

Simplifying network operations is only one part, because the one-size-fits-all approach to network infrastructure is no longer sufficient as your customers demand more personalized, flexible, and efficient services. This is where transport slicing can help, by offering a new level of customization and efficiency that directly impacts the service quality and service guarantees you can offer.

Network slicing is typically associated with delivering ultra-reliable 5G network services, but the advantages of transport slicing reach well beyond these areas. Network as a service (NaaS), for example, addresses enterprise customers’ need for more dynamic, personalized networks that are provisioned on demand, like cloud services. Using transport slicing, you can create customized virtual networks that provide customers with tailored services and control, while simplifying network management.

For telecom providers, transport slicing and automation will be critical to managing service level objectives (SLOs) of diverse, slice-based networks at scale. The transport layer plays a critical role in service delivery, and automation is essential to simplify operations and reduce manual workflows as slicing and enterprise services based on slicing become more complex.

Together, transport slicing and automation fundamentally change how network services are delivered and consumed. And while the slicing market is still in early stages of adoption, end-to-end slicing across domains offers a level of efficiency that translates into direct benefits through faster service deployment, enhanced performance, cost savings, and the ability to scale services quickly.

A complete, end-to-end automated slicing and assurance solution

Traditionally, the service monitoring and telemetry required to do any service-level assurance was an afterthought—built separately and not easily integrated into the service itself. Now, you can leverage the power of network slicing while ensuring each slice meets the stringent performance criteria your customers expect, as well as enable closed-loop automation based on end-user experiences at microsecond speeds. For example, tight integration between Cisco Crosswork Network Automation and Accedian’s performance monitoring solution provides a more complete, end-to-end automated slicing and assurance approach.

You can create and modify network slices based on real-time demand, and then leverage performance monitoring tools to not only assure the health and efficiency of these slices, but also provide empirical data to validate SLAs. You can use predictive analytics and real-time insights to identify and mitigate issues before they impact service quality, enabling increased network uptime and enhancing customer experience.

A proactive approach towards network management helps you use resources more efficiently, decrease complexity, and ensure customer satisfaction is prioritized—all while creating new opportunities for innovative revenue streams through highly differentiated and competitive service offerings. Ultimately, automated slicing and assurance drives greater operational excellence.

Fix problems before customers notice

Competition remains fierce in the telecom market, as service providers strive to meet B2B customers’ demand for high-quality services, fast service provisioning, and performance transparency. Speed is a differentiator, and customers notice immediately when service disrupts. Customers are willing to pay a premium for critical network performance, service insights, and enhanced SLAs that promise immediate resolution. To meet this demand, you need the ability to find and fix problems before customers notice.

Transport slicing and automated assurance are at the forefront of this challenge, enabling service providers to not only deliver services faster and more reliably, but to also have confidence those services will have the performance and QoE that customers expect.

The right network automation capabilities can drive simplified, end-to-end lifecycle operations, including service assurance that’s dynamic, intelligent, and automated. This paves the way for revenue-generating, premium services and delivering the outstanding experiences your customers expect.

Hiding in Plain Sight: How Subdomain Attacks Use Your Email Authentication Against You

For years, analysts, security specialists, and security architects alike have been encouraging organizations to become DMARC compliant. This involves deploying email authentication to ensure their legitimate email has the best chance of getting to the intended recipients, and for domain owners to be quickly notified of any unauthorized usage of their domains. While together we are making progress thanks to DMARC adoption and reporting services such as Cisco’s OnDMARC offering, there’s an opportunity to do better particularly with on-going monitoring to address new and emerging threats, such as this Subdo campaign.

What’s happened?

Recently a totally new attack type has been seen that takes advantage of the complacency that an organization may have when they approached their DMARC rollout with a ‘ticked the box’ mindset.

The SubdoMailing (Subdo) campaign has been ongoing for about two years now. It sends malicious mail – that is typically authenticated – from domains and subdomains that have been compromised through domain takeover and dangling DNS issues.

These attacks were initially reported by Guardio Labs who reported the discovery of 8,000 domains and 13,000 subdomains being used for these types of attacks since 2022.

Several weeks before that, Cisco’s new DMARC partner, Red Sift, discovered what they initially thought was an isolated incident of bad senders passing SPF checks and sending emails fraudulently on behalf of one of their customers. In the customer’s instance of Red Sift OnDMARC, they noticed email was coming from a sender with a poor reputation and a subdomain that appeared unrelated to their customer’s main domain. But these emails had fully passed SPF checks with the customer’s current SPF record. Upon alerting the customer who then investigated all the ‘includes’ in their SPF record, several outdated CNAME addresses were found that had been taken over by attackers, which is what caused the issue.

What should I look out for?

The bad actors in this campaign are capitalizing on stale, forgotten or misconfigured records that were wrongfully included in DNS to send unauthorized emails. The attackers then send phishing emails as images to avoid text-based spam detection.

It is this oversight that has seen many notable organizations be impacted by these new subdomain attacks in the last few months, solely because they have not been actively monitoring in the right areas.

Proactive steps to start today:

1. Don’t let your domain names expire – these are what provide fraudsters the opportunity to carry out the attack.

2. Keep your DNS clean – Remove resource records from your DNS that are no longer in use and remove third-party dependencies from your DNS when they become redundant.

3. Use a trusted email protection provider – It makes sense to use a vendor for DMARC, DKIM and SPF requirements but be sure to use a trusted vendor with the capability to proactively identify problems, such as when part of a SPF policy is void or insecure.

4. Check for dangling DNS records – Have an inventory of hostnames that are monitored continuously for dangling resource records and third-party services. When identified, remove them immediately from your DNS.

5. Monitor what sources are sending from owned domains – If the domain or subdomain is taken over for sending, then it is important to know if mail is being sent from it as quickly as possible.
