Cisco Secure Network Analytics (formerly Stealthwatch) is a security solution designed to detect advanced threats and provide enhanced network visibility. It works by monitoring and analyzing the behavior of network traffic, looking for deviations and patterns that could indicate malicious activity. Here’s an in-depth breakdown of its key components and functionalities:
Architecture
- Flow Collector:
- Role: Collects and stores NetFlow, IPFIX, sFlow, and other flow data from routers, switches, and other network devices.
- Analysis: Aggregates and enriches flow records with additional context like IP address metadata (hostname, user ID, etc.).
- Storage: Can store this data for months, providing historical analytics for security investigations.
- Management Console (SNA Manager):
- Role: The centralized interface for managing the system, performing data analysis, configuring alarms, and viewing reports.
- Visualization: Provides intuitive visualizations of network traffic patterns, incidents, and overall security posture.
- Flow Sensor:
- Role: Captures traffic from network taps or mirror ports to generate enriched flow records directly.
- Deployment: Can be deployed in-line or in a passive mode to monitor data directly.
- UDP Director:
- Role: Aggregates and replicates network telemetry data to deliver to multiple monitoring tools simultaneously.
- Load Balancing: Optimizes the delivery of data for improved efficiency.
Core Functionalities
- Behavioral Analysis:
- Anomaly Detection: Uses machine learning to identify deviations from normal traffic patterns that could indicate threats like command-and-control (C2) activity, data exfiltration, or internal lateral movement.
- Alarms: Generates alarms based on custom policies and pre-built behavioral models.
- Threat Detection:
- Advanced Malware Detection: Identifies sophisticated malware infections by analyzing network behaviors and detecting compromised devices.
- Insider Threats: Monitors user and device activity to identify unusual access patterns that could indicate internal threats.
- Network Visibility:
- Contextual Insights: Provides rich context for network traffic by correlating IP addresses with usernames, application data, and geolocation.
- Host Groups: Allows segmentation of the network into logical groups for more granular monitoring and threat detection.
- Investigation and Forensics:
- Historical Data: Enables incident investigations with access to months or even years of flow data.
- Contextual Investigation: Lets security analysts pivot from an alert to investigate related hosts and connections in detail.
Integration and Extensibility
- Third-Party Integrations: Works with SIEMs, firewalls, and other tools to enrich telemetry and enhance security workflows.
- REST APIs: Provides APIs for custom automation and data extraction.
- Cisco SecureX Integration: Offers unified threat intelligence and orchestration via Cisco’s broader security platform.
Deployment Models
- On-Premises: Appliance-based deployment for larger organizations.
- Virtual: Virtual appliances for cloud and data center environments.
- Hybrid Cloud: Combines on-premises and cloud components for flexibility and scalability.
Overall, Cisco Secure Network Analytics is a comprehensive solution focused on providing real-time network monitoring and threat detection to protect against a range of evolving security threats.
An impactful Cisco Secure Network Analytics Administrator excels in threat detection and response. They possess advanced skills in understanding behavioral analytics, network protocols, and the nuances of network traffic. This deep knowledge enables them to identify and respond to threats proactively, leveraging the behavioral analysis capabilities of the system to detect patterns that could signify breaches. Their expertise in crafting effective security policies within the platform ensures that alarms are finely tuned, minimizing false positives while maximizing detection accuracy.
Moreover, they are adept at data analysis and forensic investigations, going beyond simple alerts to provide detailed insights into root causes and possible vectors. Their ability to integrate Secure Network Analytics with other security tools like SIEMs or endpoint protection platforms ensures a comprehensive defense system, creating a multi-layered security posture that aligns with evolving threat landscapes. This separates them from the average administrator, who may lack such strategic thinking and depth of knowledge.
Pinpointing the perfect candidate requires evaluating their hands-on experience with network security tools and frameworks. Focus on those who can demonstrate experience in setting up, configuring, and fine-tuning Cisco Secure Network Analytics to align with an organization’s security needs.
