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.

Ransomware attacks can and will shut you down

By Truman Coburn

No, ransomware attacks are not random. From extortion to data breaches, ransomware is always evolving, and is becoming very lucrative with ransomware-as-a-service kit making it easier to target organizations. The days of just a single bad actor searching for vulnerabilities in your security stack are over.  Security Operations Centers (SOCs) and the security analyst community are dealing with a sophisticated global network of adversaries who can do irreversible damage. The conversation must shift from how we can prevent a breach to how do we prepare for the inevitable breach.

What happened

Recently I found out that the small private college I attended right out of high school closed their doors permanently, falling victim to a targeted ransomware attack. This institution not only provided an education but also contributed to the local economy in this rural town for over 150 years.

The cyberattack occurred during the pandemic when most educational institutions had suddenly shifted to remote learning. Adversaries knew that the shift to remote learning would expose the college’s lack of acceptable tools for monitoring and managing applications, frequently from unsecure locations.

Unfortunately, the hackers were able to halt all admission activities, locked the administrators out from accessing critical data pertaining to the upcoming school year and ultimately, forced the school to close their doors – even after they paid the hackers the ransom.

And this is not an isolated case – Comparitech published a story ‘Ransomware attacks on US schools and colleges cost $3.56bn in 2021’ and outlined how threat actors have evolved with their ransomware attacks on schools and colleges. This is particularly concerning as many of these institutions do not have the skillsets or resources to protect their students or organization from these attacks. Below you can review their findings from a study done between 2018 – 2022:

Key findings 

In 2021: 

  • 67 individual ransomware attacks on schools and colleges–a 19 percent decrease from 2020 (83) 
  • 954 separate schools and colleges were potentially affected–a 46 percent decrease from 2020 (1,753) 
  • 950,129 individual students could have been impacted–a 31 percent decrease from 2020 
  • Ransomware amounts varied from $100,000 to a whopping $40 million 
  • Downtime varied from minimal disruption (thanks to frequent data backups) to months upon months of recovery time 
  • On average, schools lose over four days to downtime and spend almost a month (30 days) recovering from the attack 
  • Hackers demanded up to $52.3 million across just six attacks and received payment in two out of 18 cases where the school/college disclosed whether or not it paid the ransom (however, they are more likely to disclose that they haven’t paid the ransom than if they have). In one case, hackers received $547,000 
  • The overall cost of these attacks is estimated at around $3.56 billion 

Protect yourself from Cyber criminals 

Just having a firewall alone will not stop all of the attacks, it’s just a matter of time before you experience a breach.  Once the breach happens, you need a security system that will quickly detect and remediate the threat .

Resiliency must be a critical outcome for any security solution and Cisco Secure Endpoint is built to stop hackers at the point of entry. Our cloud native solution allows your security operations team to quickly detect and respond to threats minutes after a breach occurs.

Securing vectors threat actors have to your network has to be the goal 

Small to medium size businesses, hospitals, and educational institutions internal network will rely on cyber insurance in-lieu of a fully staffed, skilled cyber-security team. In today’s climate of ever-increasing sophisticated cyber threats this won’t cut it. You will need an agent that quickly detects, responds, and has visibility across your different security solutions.

With Cisco Secure Endpoint Pro we are equipped to assist with the responsibility of monitoring your endpoints for cyberattacks.  With 24/7/365 monitoring capabilities, our SOC will quickly detect and remediate any threats that targets your organization. Secure endpoint pro provides flexibility and the option of letting our SOC team do the heavy lifting while you focus on your core business.

Tangible outcomes provided by Secure Endpoint and Secure Endpoint Pro:

  • Stop threats before you’re compromised
  • Remediate faster and more completely
  • Maximize your security operations – Focus on the most important threats and gain always on security with managed EDR

Limit the amount of time threat actors have to your network

An effective managed endpoint detection and response solution frees up time for your SOC team along with accelerating detection and response time.  Cisco Secure Endpoint can reduce incident response time by as much as 97%, which limits the damage threat actors can cause after you have been breached.

Cisco Security has launched a solution geared towards protecting your school’s network by blocking malicious threats before they enter the endpoint and compromising your data. The secure endpoint agent is deployed, sits on the school endpoint freeing up time from a stretched thin IT department.
