Empowering Cybersecurity with AI: The Future of Cisco XDR

In 2007, there was a study from the University of Maryland proving that internet-connected systems were attacked every 39 seconds on average. Today, that number has grown more than 60%. Cisco sees 64 attempts to connect to ransomware infrastructure every second. The world is becoming digitized, and hybrid, which creates an environment that criminals target with increasing sophistication. It’s too much for human-scale, and so a hybrid world requires a hybrid approach that sits between humans and machines.

Envision an AI Assistant that serves as a reliable partner for incident responders, offering precise, real-time guidance on the subsequent steps to take, tailored to the specific state of the incident at hand and allowing SOC (Security Operations Center) teams to respond faster and do more with less. I am pleased to announce the launch of the AI Assistant in XDR as a part of our Breach Protection Suite.

In our RSAC 2023 announcement, we introduced a vision of our Cisco SOC Assistant, designed to expedite threat detection and response. Today, this vision is realized and available in private preview. It enhances our Breach Protection Suite which is powered by Cisco XDR’s capabilities. It significantly speeds up investigations and responses, enabling security teams to safeguard their environments more efficiently and cost-effectively.

Assist with Information Discovery

In 2024, the global shortfall of 3.5 million security professionals, as reported by ISC2, underscores the importance of retaining and recruiting skilled personnel to counter increasingly sophisticated cyber threats and safeguard enterprises. Moreover, the lack of appropriate tools often leads to ineffective cyber risk management and professional burnout, adversely affecting staff retention and the SOC’s capacity to thwart attacks.

The AI Assistant in XDR acts as a potent enhancer, empowering SOC teams to maximize their efficiency and effectively close the personnel and skill gap. When an incident occurs, the assistant will contextualize events across email, the web, endpoints, and the network to tell the SOC analyst exactly what happened and its impact on their environment. It presents a short description of the incident that quickly answers what, when and how an incident happened. It also provides a long description of the incident which explains the timeline of events that have happened in this active incident.

Augment and Elevate SOC Teams with Best Practice Recommendations

Today’s SOCs often struggle with a fragmented technology stack, making it difficult to respond effectively to cyber threats. Alert fatigue is a major hurdle for modern SOC teams, hindering proactive threat hunting and leading to overlooked alerts and burnout. The Cisco AI Assistant comes to the rescue and jumpstarts the incident response process for a modern SOC team.

Our AI Assistant, powered by Cisco XDR the platform for Cisco’s Breach Protection Suite, synthesizes data from email, web, processes, endpoints, cloud, and network domains, offering precise action recommendations to effectively contain ongoing cyber-attacks. It works at machine scale to identify patterns and potential attacks that humans might miss because of alert fatigue, if a defender is only looking at one domain in isolation, or while trying to manually correlate data. The AI Assistant is context aware, meaning it tracks the state of the incident in real-time and generates tailored recommendations specific to that incident.

Figure 4: Tailored Recommendations for an Incident by the AI Assistant

Mean Time to Detection (MTTD) and Mean Time to Respond (MTTR) are two primary metrics that SOC teams want to optimize for. Cisco XDR with our AI Assistant enables security teams to reduce these metrics by jumpstarting investigations and incident response by providing tailored recommendations for that specific incident.

Enable Seamless Collaboration Across Security Teams

The Cisco AI Assistant, embedded within XDR, facilitates team collaboration using Webex, Teams, or Slack. This empowers security teams to swiftly assemble the right experts for an active incident, thereby speeding up the MTTR. The AI Assistant unifies the team by setting up WAR rooms, summarizing messages, and logging them in XDR for instant audit-readiness.

Figure 5: AI Assistant creates a Webex WAR Room and brings the right experts together for Incident Response

Automate Workflows to Neutralize Threats Across the Enterprise

Today’s SOCs often lack a cohesive technology stack to respond to cyber threats efficiently and consistently. As the IT environment grows beyond the on-premises data center to cloud, hybrid-cloud and multi-cloud country specific data centers, organizations accumulate point solutions to monitor and protect pieces of the environment. As a result, SOC analysts must do a lot of the heavy lifting required to detect and respond to an attack. This includes logging into different tools to execute workflows that contain an attack.

Our AI Assistant taps into advanced workflows and atomics with Cisco XDR’s 90+ integrations. Our AI assistant enables the execution of workflows at a single click, guided by the AI Assistant’s personalized recommendations that consider the incident’s playbook and current state in real-time.

Figure 6: Execution of Automated Workflows by the AI Assistant to Contain an Incident

Gone are the days when security teams had to juggle multiple isolated products and execute workflows in each to mitigate an attack. With Cisco Breach Protection Suite, billions of security events can be correlated and recommended actions can be generated and executed all in one place. This is the transformative power of the Cisco XDR combined with Cisco’s AI Assistant revolutionizing enterprise security.

Computing that’s purpose-built for a more energy-efficient, AI-driven future

Just as humans use patterns as mental shortcuts for solving complex problems, AI is about recognizing patterns to distill actionable insights. Now think about how this applies to the data center, where patterns have developed over decades. You have cycles where we use software to solve problems, then hardware innovations enable new software to focus on the next problem. The pendulum swings back and forth repeatedly, with each swing representing a disruptive technology that changes and redefines how we get work done with our developers and with data center infrastructure and operations teams.

AI is clearly the latest pendulum swing and disruptive technology that requires advancements in both hardware and software. GPUs are all the rage today due to the public debut of ChatGPT – but GPUs have been around for a long time. I was a GPU user back in the 1990s because these powerful chips enabled me to play 3D games that required fast processing to calculate things like where all those polygons should be in space, updating visuals fast with each frame.

In technical terms, GPUs can process many parallel floating-point operations faster than standard CPUs and in large part that is their superpower. It’s worth noting that many AI workloads can be optimized to run on a high-performance CPU.  But unlike the CPU, GPUs are free from the responsibility of making all the other subsystems within compute work with each other. Software developers and data scientists can leverage software like CUDA and its development tools to harness the power of GPUs and use all that parallel processing capability to solve some of the world’s most complex problems.

A new way to look at your AI needs

Unlike single, heterogenous infrastructure use cases like virtualization, there are multiple patterns within AI that come with different infrastructure needs in the data center. Organizations can think about AI use cases in terms of three main buckets:

1. Build the model, for large foundational training.

2. Optimize the model, for fine-tuning a pre-trained model with specific data sets.

3. Use the model, for inferencing insights from new data.

The least demanding workloads are optimize and use the model because most of the work can be done in a single box with multiple GPUs. The most intensive, disruptive, and expensive workload is build the model. In general, if you’re looking to train these models at scale you need an environment that can support many GPUs across many servers, networking together for individual GPUs that behave as a single processing unit to solve highly complex problems, faster.

This makes the network critical for training use cases and introduces all kinds of challenges to data center infrastructure and operations, especially if the underlying facility was not built for AI from inception. And most organizations today are not looking to build new data centers.

Therefore, organizations building out their AI data center strategies will have to answer important questions like:

• What AI use cases do you need to support, and based on the business outcomes you need to deliver, where do they fall into the build the model, optimize the model, and use the model buckets?
• Where is the data you need, and where is the best location to enable these use cases to optimize outcomes and minimize the costs?
• Do you need to deliver more power? Are your facilities able to cool these types of workloads with existing methods or do you require new methods like water cooling?
• Finally, what is the impact on your organization’s sustainability goals?

The power of Cisco Compute solutions for AI

As the general manager and senior vice president for Cisco’s compute business, I’m happy to say that Cisco UCS servers are designed for demanding use cases like AI fine-tuning and inferencing, VDI, and many others.

You can say that with UCS, you get the muscle to power your creativity and the brains to optimize its use for groundbreaking AI use cases.

But Cisco is one player in a wide ecosystem. Technology and solution partners have long been a key to our success, and this is certainly no different in our strategy for AI. This strategy revolves around driving maximum customer value to harness the full long-term potential behind each partnership, which enables us to combine the best of compute and networking with the best tools in AI.

This is the case in our strategic partnerships with NVIDIA, Intel, AMD, Red Hat, and others. One key deliverable has been the steady stream of Cisco Validated Designs (CVDs) that provide pre-configured solution blueprints that simplify integrating AI workloads into existing IT infrastructure. CVDs eliminate the need for our customers to build their AI infrastructure from scratch. This translates to faster deployment times and reduced risks associated with complex infrastructure configurations and deployments.

Another key pillar of our AI computing strategy is offering customers a diversity of solution options that include standalone blade and rack-based servers, converged infrastructure, and hyperconverged infrastructure (HCI). These options enable customers to address a variety of use cases and deployment domains throughout their hybrid multicloud environments – from centralized data centers to edge end points. Here are just a couple of examples:

• Converged infrastructures with partners like NetApp and Pure Storage offer a strong foundation for the full lifecycle of AI development from training AI models to day-to-day operations of AI workloads in production environments. For highly demanding AI use cases like scientific research or complex financial simulations, our converged infrastructures can be customized and upgraded to provide the scalability and flexibility needed to handle these computationally intensive workloads efficiently.
• We also offer an HCI option through our strategic partnership with Nutanix that is well-suited for hybrid and multi-cloud environments through the cloud-native designs of Nutanix solutions. This allows our customers to seamlessly extend their AI workloads across on-premises infrastructure and public cloud resources, for optimal performance and cost efficiency. This solution is also ideal for edge deployments, where real-time data processing is crucial.

AI Infrastructure with sustainability in mind 

Cisco’s engineering teams are focused on embedding energy management, software and hardware sustainability, and business model transformation into everything we do. Together with energy optimization, these new innovations will have the potential to help more customers accelerate their sustainability goals.

Working in tandem with engineering teams across Cisco, Denise Lee leads Cisco’s Engineering Sustainability Office with a mission to deliver more sustainable products and solutions to our customers and partners. With electricity usage from data centers, AI, and the cryptocurrency sector potentially doubling by 2026, according to a recent International Energy Agency report, we are at a pivotal moment where AI, data centers, and energy efficiency must come together. AI data center ecosystems must be designed with sustainability in mind. Denise outlined the systems design thinking that highlights the opportunities for data center energy efficiency across performance, cooling, and power in her recent blog, Reimagine Your Data Center for Responsible AI Deployments.

Recognition for Cisco’s efforts have already begun. Cisco’s UCS X-series has received the Sustainable Product of the Year by SEAL Awards and an Energy Star rating from the U.S. Environmental Protection Agency. And Cisco continues to focus on critical features in our portfolio through agreement on product sustainability requirements to address the demands on data centers in the years ahead.

Look ahead to Cisco Live

We are just a couple of months away from Cisco Live US, our premier customer event and showcase for the many different and exciting innovations from Cisco and our technology and solution partners. We will be sharing many exciting Cisco Compute solutions for AI and other uses cases.

Bridging the Digital Divide with Subscriber Edge

Bridging the digital divide has been a longstanding top priority for countries globally. According to Broadband Research, in 2023 approximately five billion people (64% of the world’s population) were connected to the internet. That means roughly three billion people do not have the basic digital necessities such as access to data, sharing information, or communicating. In addition, they do not have the same access to educational, employment, and economic opportunities that could improve the quality of their lives through digital connections.

The World Bank has estimated that increasing the percentage of people with internet access to 75% would “boost the developing world’s collective GDP by $2 trillion and create 140 million new jobs.”

The good news is that the public and private sectors have been partnering to help close the digital divide, but as Broadband Research states: “Factors like increased affordability of devices, improved infrastructure and innovative services drive this growth.”

Role of subscriber edge

Accessing the internet requires a subscription to a broadband service from communications service providers (CSPs), using either cable, fiber, DSL, fixed wireless access (FWA), satellite or 4G/5G infrastructure and devices. Subscriber edge is the access point function for subscribers in a service provider network through which they connect to the broadband network for high-speed connectivity, such as accessing the internet.

Subscriber edge can be deployed with other services on the same platform by converging residential and enterprise services using multiservice nodes. Subscriber edge solutions involve managing subscriber sessions, and include functions like IP address management, policy and quality of service (QoS) enforcement, and secure access to the network through authentication and billing.

Shifting application and traffic demands

Traditional approaches for offering broadband services can be revenue-impacting and could affect the quality of experience (QoE) for a broadband user (see Figure 1). For example, with the advancement of applications and evolving transport protocols—such as Quick UDP Internet Connections (QUIC) and Transmission Control Protocol/ Transport Layer Security (TCPLS)—traffic patterns within broadband networks are experiencing a shift away from traditional transport protocols. These new protocols offer greater control to end-user applications, which reduces the dependency on the underlying broadband network and requires relatively simpler QoS models.

This shift is a pivotal opportunity for CSPs to simplify and modernize their complex traditional broadband networks to address higher bandwidth demands, growing user base, increasing video traffic and rising costs. As a result, there is a need to relook at subscriber edge with the overall subscriber services network design, and address important areas such as:

• Subscriber anchor point in the network
• Selection of subscriber edge devices and architecture
• Improve end-user experience and offer new services
• Address rising network costs

Understanding MPLS

MPLS, or Multiprotocol Label Switching, is a legacy networking technology commonly used for building private, high-performance WANs. MPLS operates by assigning labels to network packets, enabling routers to make forwarding decisions based on these labels rather than IP addresses.

Key Features of MPLS:

1. Traffic Engineering: MPLS networks support traffic engineering capabilities, allowing administrators to optimize network paths and allocate bandwidth efficiently.
2. Quality of Service (QoS): MPLS offers robust QoS mechanisms, ensuring that critical applications receive the necessary bandwidth and latency guarantees to maintain optimal performance.
3. Security: MPLS inherently provides a higher level of security compared to public internet connections, as traffic remains within the confines of the private MPLS network, reducing exposure to external threats.
4. Reliability: MPLS networks are known for their reliability and predictability, making them ideal for applications that require consistent performance and uptime.

Contrasting SD-WAN and MPLS

While both SD-WAN and MPLS serve the purpose of connecting geographically dispersed locations within an organization, they differ significantly in terms of architecture, cost, and flexibility.

Architecture:

• SD-WAN: SD-WAN architectures are decentralized and software-driven, offering flexibility and scalability to adapt to changing network requirements rapidly.
• MPLS: MPLS networks are centralized and hardware-dependent, typically requiring substantial upfront investments in infrastructure and equipment.

Cost:

• SD-WAN: SD-WAN solutions often provide cost savings compared to MPLS, particularly for organizations with diverse connectivity requirements or those seeking to augment MPLS with lower-cost internet links.
• MPLS: MPLS services can be costly, primarily due to the need for dedicated circuits and long-term contracts with service providers.

Flexibility:

• SD-WAN: SD-WAN architectures offer unparalleled flexibility, allowing organizations to seamlessly integrate various transport technologies and cloud services into their network environments.
• MPLS: MPLS networks are less flexible, with limited support for cloud connectivity and scalability compared to SD-WAN solutions.

Conclusion

In summary, both SD-WAN and MPLS have their merits and are suited to different network environments and business requirements. SD-WAN excels in providing agility, cost efficiency, and flexibility, making it an attractive option for organizations seeking to modernize their network infrastructure. On the other hand, MPLS offers reliability, security, and quality of service, making it well-suited for mission-critical applications and industries with stringent compliance requirements.

Ultimately, the choice between SD-WAN and MPLS depends on factors such as budget, performance needs, and organizational priorities. By understanding the nuances of each technology, organizations can make informed decisions that align with their strategic objectives and drive business success.
