Accelerate XDR Outcomes with NDR and EDR

By Hanna Jabbour

Cybersecurity attacks complication and damaging impact are always keeping SOC analyst at their edge. Extended Detection and Response (XDR) solutions tend to simplify for Sam, a SOC analyst, his job by simplifying the workflow and process that involve the lifecycle of a threat investigation from detection to response. In this post we will explore how SecureX, Secure Cloud Analytics (NDR), Secure Endpoint (EDR) with their seamless integration accelerate the ability to achieve XDR outcomes. 

Meaningful incidents  

One of the first challenges for Sam is alert fatigue. With the overwhelming number of alerts coming from multiple sources and the lack of relevance or correlation, decreases the value of these alerts to the point that they become as meaningless as having none. To counter this effect, Cisco Secure Cloud Analytics and Cisco Secure Endpoint limit alert promotion to SecureX to only include high fidelity alerts with critical severity and marking them as High Impact incidents within SecureX Incident manager.

Figure 1

This capability reduces the noise coming from the source, while keeping the other alerts available for investigation, putting impactful incidents at the top of Sam’s to do list. Now, Sam is confident that his time is spent in a prioritized manner and helps ensure he is tackling the most important threats first. Automatic incident provisioning accelerates incident response by bringing focus on the most impactful incidents.

Valuable enrichment

Understanding the mechanics and data around a specific incident is a key factor for Remi, an incident responder, in his day-to-day work. Achieving his tasks accurately is tightly coupled with his ability to scope and understand the impact of an incident and to gather all possible data from the environment which can be associated with an incident including devices, users, files hashes, email ids, domains IPs and others. SecureX Incident Manager’s automatic enrichment capability completes this data collection for high impact incidents automatically. The data is then classified into targets, observables, and indicators and added to the incident to help the analyst better understand the incident’s scope and potential impact.

Figure 2

The Incident Manager and automatic enrichment provides Remi with crucial information such as the associated MITRE Tactics and Techniques applied during this incident, the contributing threat vectors, and security solutions. In addition, the Incident Manager aggregates events from multiple sources into the same high impact incident that the enrichment was triggered on future providing Remi with more vital context.

Figure 3

This automatic enrichment for high impact incidents is essential to Remi’s understanding as much as possible about an incident as it occurs and significantly accelerates him identifying the proper response for the threat.  This brings us to the next step in our incident detection to response workflow.

Faster response and investigations

It is important for an XDR to correlate the right information for the Security Analyst and incident responder to understand an attack but it is equally important to provide an effective response mechanism. This is exactly what SecureX provides with the ability to apply a response to an observable with a simple a single click or through automation.

These workflows can be invoked to block a domain, IP or URL across a full environment with a simple click, leveraging existing integrations such as firewalls or umbrella and others. Workflows can be made available to the threat response pivot menu where they are useful for performing specific host specific actions, such as isolate a host, take a host snapshot, and more.

In addition to response workflows, the pivot menu provides the ability to leverage Secure Cloud Analytics (SCA) telemetry by generating a case book linking back to telemetry searches within SCA.  This automation is critical to understanding the spread of a threat across an environment. A good example on this, is identifying all hosts communicating to a command-and-control destination before this destination was identified as malicious.  This is a pre-existing SecureX workflow which can be taken advantage of today see workflow 0005 – SCA – Generate Case book with Flow Links.

Automating responses

Reducing time to remediation is a key aspect of keeping a business secure, SecureX orchestration automates responses with various solutions specially with NDR detections from SCA and use observables from these alerts to isolate hosts leveraging Secure Endpoint.  SCA can send alerts via Webhooks and SecureX Orchestration receive them as triggers to launch an NDR- EDR workflow to isolate hosts automatically. (0014-SCA-Isolate endpoints from alerts)

This orchestration workflow automatically isolates rogue devices in a network or contain confirmed threat alerts received from Cisco’s Machine learning threat detection cloud and can be used for multiple different response scenarios.

The power of automation brought by SecureX, Secure Cloud Analytics and Secure Endpoint accelerates XDR outcomes drastically which simplifies Security Analyst (Sam) and Incident Responder (Remi) jobs and make it more efficient with accurate incident prioritization, automatic investigation/enrichment and most importantly automating responses.

Cisco Talos — Our not-so-secret threat intel advantage

By Neville Letzerich

Security tools are only as good as the intelligence and expertise that feeds them. We’re very fortunate to have our security technologies powered by Cisco Talos, one of the largest and most trusted threat intelligence groups in the world. Talos is comprised of highly skilled researchers, analysts, and engineers who provide industry-leading visibility, actionable intelligence, and vulnerability research to protect both our customers and the internet at large.

The Talos team serves as a crucial pillar of our innovation — alerting customers and the public to new threats and mitigation tactics, enabling us to quickly incorporate protection into our products, and stepping in to help organizations with incident response, threat hunting, compromise assessments and more. Talos can also be found securing large-scale events such as the Super Bowl, and working with government and law enforcement organizations across the globe to share intelligence.

With Cisco’s vast customer base and broad portfolio — from routers and switches to email and endpoints — Talos has visibility into worldwide telemetry. Once a threat is seen, whether it’s a phishing URL or an IP address hosting malware, detections are created and indicators of compromise are categorized and blocked across our Cisco Secure portfolio.

Talos also leverages its unique insights to help society as a whole better understand and combat the cyberattacks facing us daily. During the war in Ukraine, the group has taken on the additional task of defending over 30 critical infrastructure providers in the country by directly managing and monitoring their endpoint security.

How Talos powers XDR

The reality of security today is that organizations must be constantly ready to detect and contain both known and unknown threats, minimize impact, and keep business going no matter what happens in the cyber realm. In light of hybrid work, evolving network architectures, and increasingly insidious attacks, all organizations must also be prepared to rapidly recover if disaster strikes, and then emerge stronger. We refer to this as security resilience, and Talos plays a critical role in helping our customers achieve it.

For several years, our integrated, cloud-native Cisco SecureX platform has been delivering extended detection and response (XDR) capabilities and more. SecureX allows customers to aggregate, analyze, and act on intelligence from disparate sources for a coordinated response to cyber threats.

Through the SecureX platform, intelligence from Talos is combined with telemetry from our customers’ environments — including many third-party tools — to provide a more complete picture of what’s going on in the network. Additionally, built-in, automated response functionality helps to speed up and streamline mitigation. This way, potential attacks can be identified, prioritized, and remediated before they lead to major impact.

For XDR to be successful, it must not only aggregate data, but also make sense of it. Through combined insights from various resources, SecureX customers obtain the unified visibility and context needed to rapidly prioritize the right threats at the right time. With SecureX, security analysts spend up to 90 percent less time per incident.

Accelerating threat detection and response

One of Australia’s largest universities, Deakin University, needed to improve its outdated security posture and transition from ad hoc processes to a mature program. Its small security team sought an integrated solution to simplify and strengthen threat defense.

With a suite of Cisco security products integrated through SecureX, Deakin University was able to reduce the typical investigation and response time for a major threat down from over a week to just an hour. The university was also able to decrease its response time for malicious emails from an hour to as little as five minutes.

“The most important outcome that we have achieved so far is that security is now a trusted function.”

– Fadi Aljafari, Information Security and Risk Manager, Deakin University

Also in the education space, AzEduNet provides connectivity and online services to 1.5 million students and 150,000 teachers at 4,300 educational institutions in Azerbaijan. “We don’t have enough staff to monitor every entry point into our network and correlate all the information from our security solutions,” says Bahruz Ibrahimov, senior information security engineer at AzEduNet.

The organization therefore implemented Cisco SecureX to accelerate investigations and incident management, maximize operational efficiency with automated workflows, and decrease threat response time. With SecureX, AzEduNet has reduced its security incidents by 80 percent.

“The integration with all our Cisco Secure solutions and with other vendors saves us response and investigation time, as well as saving time for our engineers.”

– Bahruz Ibrahimov, Senior Information Security Engineer, AzEduNet

Boosting cyber resilience with Talos

The sophistication of attackers and sheer number of threats out there today make it extremely challenging for most cybersecurity teams to effectively stay on top of alerts and recognize when something requires their immediate attention. According to a survey by ESG, 81 percent of organizations say their security operations have been affected by the cybersecurity skills shortage.

That’s why Talos employs hundreds of researchers around the globe — and around the clock — to collect and analyze massive amounts of threat data. The group uses the latest in machine learning logic and custom algorithms to distill the data into manageable, actionable intelligence.

“Make no mistake, this is a battle,” said Nick Biasini, head of outreach for Cisco Talos, who oversees a team of global threat hunters. “In order to keep up with the adversaries, you really need a deep technical understanding of how these threats are constructed and how the malware operates to quickly identify how it’s changing and evolving. Offense is easy, defense is hard.”

Maximizing defense against future threats  

Earlier this year, we unveiled our strategic vision for the Cisco Security Cloud to deliver end-to-end security across hybrid, multicloud environments. Talos will continue to play a pivotal role in our technology as we execute on this vision. In addition to driving protection in our products, Talos also offers more customized and hands-on expertise to customers when needed.

Cisco Talos Incident Response provides a full suite of proactive and emergency services to help organizations prepare for, respond to, and recover from a breach — 24 hours a day. Additionally, the recently released Talos Intel on Demand service delivers custom research unique to your organization, as well as direct access to Talos security analysts for increased awareness and confidence.

Unscrambling Cybersecurity Acronyms: The ABCs of Endpoint Security

By Nirav Shah

Ransomware and other advanced attacks continue to evolve and threaten organizations around the world. Effectively defending your endpoints from these attacks can be a complex undertaking, and a seemingly endless number of security acronyms only compounds that complexity. There are so many acronyms – EPP, EDR, MEDR, MDR, XDR, and more – for various cybersecurity products and services that it becomes difficult to understand the differences between them and choose the right solution for your organization. Deciphering all these acronyms is a task on its own and deciding which solution works best for you is even more challenging.

We here at Cisco believe that understanding these acronyms and determining which security products or services are the best fit for your organization’s needs doesn’t have to be so hard. That’s why we developed this blog – the first in a series – to give you an overview of the different types of threat detection and response solutions.

This series will help you understand the benefits and disadvantages of each solution, the similarities and differences between these solutions, and how to identify the right solution for your organization. Now let’s go over the different types of security solutions.

Overview of Threat Detection and Response Solutions

There are several types of threat detection and response solutions, including:

  • Endpoint Detection and Response (EDR) A product that monitors, detects, and responds to threats across your endpoint environment
  • Managed Endpoint Detection and Response (MEDR) A managed service operated by a third-party that monitors, detects, and responds to threats across your endpoint environment
  • Managed Detection and Response (MDR) A managed service operated by a third-party that monitors, detects, and responds to threats across your cybersecurity environment
  • Extended Detection and Response (XDR) A security platform that monitors, detects, and responds to threats across your cybersecurity environment with consolidated telemetry, unified visibility and coordinated response

These solutions are similar in that they all enable you to detect and respond to threats, but they differ by the environment(s) being monitored for threats, who conducts the monitoring, as well as how alerts are consolidated and correlated. For instance, certain solutions will only monitor your endpoints (EDR, MEDR) while others will monitor a broader environment (XDR, MDR). In addition, some of these solutions are actually managed services where a third-party monitors your environment (MEDR, MDR) versus solutions that you monitor and manage yourself (EDR, XDR).

How to Select the Right Solution for your Organization

When evaluating these solutions, keep in mind that there isn’t a single correct solution for every organization. This is because each organization has different needs, security maturities, resource levels, and goals. For example, deploying an EDR makes sense for an organization that currently has only a basic anti-virus solution, but this seems like table stakes to a company that already has a Security Operations Center (SOC).

That being said, there are a few questions you can ask yourself to find the cybersecurity solution that best fits your needs, including:

  • What are our security goals? Where are we in our cybersecurity journey?
  • Do we have a SOC or want to build a SOC?
  • Do we have the right cybersecurity talent, skills, and knowledge?
  • Do we have enough visibility and context into security incidents? Do we suffer from too many alerts and/or too many security tools?
  • How long does it take us to detect and respond to threats? Is that adequate?

Of these questions, the most critical are about your security goals and current cybersecurity posture. For instance, organizations at the beginning of their security journey may want to look at an EDR or MEDR solution, while companies that are further along their journey are more likely to be interested in an XDR. Asking whether you already have or are willing to build out a SOC is another essential question. This will help you understand whether you should run your security yourself (EDR, XDR) or find a third-party to manage it for you (MEDR, MDR).

Asking whether you have or are willing to hire the right security talent is another critical question to pose. This will also help determine whether to manage your cybersecurity solution yourself or have a third-party run it for you. Finally, questions about visibility and context, alert, and security tool fatigue, as well as detection and response times will help you to decide if your current security stack is sufficient or if you need to deploy a next-generation solution such as an XDR.

These questions will help guide your decision-making process and give you the information you need to make an informed decision on your cybersecurity solution. For more details on the different endpoint security acronyms and how to determine the right solution for your organization, keep an eye out for the next blog in this series – Unscrambling Cybersecurity Acronyms: The ABCs of EDR and MEDR.

Get Comprehensive Insights into Your Network with Secure Analytics and MITRE Mappings

By Claudio Lener

A deep dive into the latest updates from Secure Network and Cloud Analytics that show Cisco’s leadership in the Security Industry.

The year 2022 has been rather hectic for many reasons, and as the World undergoes its various challenges and opportunities, We At Cisco Security have buckled up and focused on improving the World in the way which we know best: by making it more Secure.

In an increasingly vulnerable Internet environment, where attackers rapidly develop new techniques to compromise organizations around the world, ensuring a robust security infrastructure becomes ever more imperative. Across the Cisco Security Portfolio, Secure Network Analytics (SNA) and Secure Cloud Analytics (SCA) have continued to add value for their customers since their inception by innovating their products and enhancing their capabilities.

In the latest SNA 7.4.1 release, four core features have been added to target important milestones in our roadmap. As a first addition, SNA has widely expanded on its Data Store deployment options by introducing the single node Data Store; supporting existing Flow Collector (FC) and new Data Store expansion by the Manager; and the capacity to mix and match virtual and physical appliances to build a Data Store deployment.

The SNA Data Store started as a simple concept, and while it maintained its simplicity, it became increasingly more robust and performant over the recent releases. In essence, it represents a new and improved database architecture design that can be made up of virtual or physical appliances to provide industry leading horizontal scaling for telemetry and event retention for over a year. Additionally, the Flow Ingest from the Flow Collectors is now separate from the data storage, which allows them to now scale to 500K + Flows Per Second (FPS). With this new database design, are now optimized for performance, which has improved across all metrics by a considerable amount.

For the second major addition, SNA now supports multi-telemetry collection within a single deployment. Such data encompasses network telemetry, firewall logging, and remote worker telemetry. Now, Firewall logs can be stored on premises with the Data Store, making data available to the Firepower Management Center (FMC) via APIs to support remote queries. From the FMC, users can pivot directly to the Data Store interface and look at detailed events that optimize SecOps workflows, such as automatically filtering on events of interest.

On the topic of interfaces, users can now benefit from an intelligent viewer which provides all Firewall data. This feature allows to select custom timeframes, apply unique filters on Security Events, create custom views based on relevant subsets of data, visualize trends from summary reports, and finally to export any such view as a CSV format for archiving or further forensic investigations.

With respect to VPN telemetry, the AnyConnect Secure Mobility Client can now store all network traffic even if users are not using their VPN in the given moment. Once a VPN connection is restored, the data is then sent to the Flow Collector, and, with a Data Store deployment, off-network flow updates can bypass FC flow caches which allow NVM historical data to be stored correctly.

Continuing down the Data Store journey (and, what a journey indeed), users can now monitor and evaluate its performance in a simple and intuitive way. This is achieved with charts and trends directly available in the Manager, which can now support traditional non-Data Store FCs and one singular Data Store. The division of Flow Collectors is made possible by SNA Domains, where a Data Store Domain can be created, and new FCs added to it when desired. This comes as part of a series of robust enhancements to the Flow Collector, where the FC can now be made up of a single image (NetFlow + sFlow) and its image can be switched between the two options. As yet another perk of the new database design, any FC can send its data to the Data Store.

As it can be seen, the Data Store has been the star of the latest SNA release, and for obvious good reasons. Before coming to an ending though, it has one more feature up its sleeve: Converged Analytics. This SNA feature brings a simplified, intuitive and clear analytics experience to Secure Network Analytics users. It comes with out- of-the-box detections mapped to MITRE with clearly defined tactics and techniques, self-taught baselining and graduated alerting, and the ability to quiet non-relevant alerts, leading to more relevant detections.

This new Analytics feature is a strong step forward to give users the confidence of network security awareness thanks to an intuitive workflow and 43 new alerts. It also gives them a deep understanding of each alert with observations and mappings related to the industry-standard MITRE tactics and techniques. When you think it couldn’t get any better, the Secure Network and Cloud Analytics teams have worked hard to add even more value to this release, and ensured the same workflows, functionality and user experience could be further available in the SCA portal. Yes, this is the first step towards a more cohesive experience across both SNA and SCA, where users of either platform will start to benefit from more consistent outcomes regardless of their deployment model. As some would say, it’s like a birthday coming early.

Pivoting to Secure Cloud Analytics, as per Network sibling, the product got several enhancements over the last months of development. The core additions revolve around additional detections and context, as well as usability and integration enhancements, including those in Secure Cloud Insights. In parallel with SNA’s Converged Analytics, SCA benefits from detections mapped to the MITRE ATT&CK framework. Additionally, several detections underwent algorithm improvements, while 4 new ones were added, such as Worm Propagation, which was native to SNA. Regarding the backbone of SCA’s alerts, a multitude of new roles and observations were added to the platform, to further optimize and tune the alerts for the users.

Additionally, alerts now offer a pivot directly to AWS’ load balancer and VPC, as well as direct access to Azure Security Groups, to allow for further investigation through streamlined workflows. The two Public Cloud Providers are now also included in coverage reports that provide a gap analysis to gain insight as to what logs may have potentially gone missing.

Focusing more on the detection workflows, the Alert Details view also got additional information pertaining to device context which gives insight into hostnames, subnets, and role metrics. The ingest mechanism has also gotten more robust thanks to data now coming from Talos intelligence feed and ISE, shown in the Event Viewer for expanded forensics and visibility use cases.

While dealing with integrations, the highly requested SecureX integration can now be enabled in 1 click, with no API keys needed and a workflow that is seamless across the two platforms. Among some of the other improvements around graphs and visualizations, the Encrypted Traffic widget now allows an hourly breakdown of the data, while the Event Viewer now displays bi-directional session traffic, to bring even greater context to SCA flows.

In the context of pivots, as a user is navigating through devices that, for example, have raised an alert, they will now also see the new functionality to pivot directly into the Secure Cloud Insights (SCI) Knowledge Graph, to learn more about how various sources are connected to one another. Another SCI integration is present within the Device Outline of an Alert, to gain more posture context, and as part of a configuration menu, it’s now possible to run cloud posture assessments on demand, for immediate results and recommendations.

With this all said, we from the Secure Analytics team are extremely excited about the adoption and usage of these features so that we can keep on improving the product and iterating to solve even more use cases. As we look ahead, the World has never needed more than now a comprehensive solution to solve one of the most pressing problems in our society: cyber threats in the continuously evolving Internet space. And Secure Analytics will be there, to pioneer and lead the effort for a safe World.

ESG’s Report on the Role of XDR in SOC Modernization

By Bob Stockwell

Extended Detection and Response, or XDR, the cybersecurity topic that dominated the RSA conference 2022 show floor with multiple vendors, has been getting a lot of attention lately, and for good reason. A connected, unified approach to detection and response promises to give security professionals all the tools and capabilities they need to address the ever-growing attack surface.

At Cisco, we wanted to get an independent view of what XDR means to a security operations audience, so we partnered with ESG on a survey conducted in April 2022 of 376 IT cybersecurity professionals in North America, which explored some key questions and trends for security operations centers as it relates to XDR. This new eBook, SOC Modernization and the Role of XDR, provides insights into the survey. Unsurprisingly, 52 percent of organizations surveyed believe that security operations are more challenging than just two years ago, and it’s clear cybersecurity professionals are looking for the next architecture to solve these challenges.

81% dealing with cybersecurity skills shortage: Source: ESG Research Study, SOC Modernization and the Role of XDR, June 2022

More Threats, More Data, More Action

The distributed nature of the network is resulting in more data from multiple control points. The survey showed that while 80 percent of organizations are already using more than 10 data sources as a part of their security operations, they want even more as they realize the value of being able to aggregate, normalize, correlate, and contextualize data so they can take better actions faster. At the same time, 81 percent say that they have been impacted by the cybersecurity skills shortage, and more data without the capabilities and skills in place to act will only diminish the ability to address threats.

To help fill those skills gaps, improved threat detection playbooks and incident prioritization will be critical aspects of the security operations strategy. Another key tool widely recognized as important in building a foundation is the MITRE ATT&CK framework that can help your teams focus and understand adversary tactics and techniques based on real-world observations.

While a common industry definition remains elusive, one thing is clear: XDR will play a critical role in the modernization of the security operations center. Determining how it will help your security operations team, and which partners to work with as you build out your XDR approach, will determine your level of success.

Redefining simplicity and efficiency with XDR

You need XDR to transform your infrastructure from a series of disjointed solutions into a fully integrated ecosystem that gets you to your outcome more effectively and efficiently. Cisco has built XDR capabilities into the broad portfolio of our security products and easily integrates with existing solutions in your environment using open APIs. After you’ve read the ESG SOC Modernization and the Role of XDR eBook, we invite you to take a look at the Cisco XDR Buyer’s Guide, which outlines five key elements of XDR done right and provides some questions to ask as you consider which vendors you want to work with in building out your security strategy. Don’t wait to start planning how XDR will help your security operations team.
