Project Description

Visibility and Threat Detection for the Enterprise Network

Today’s enterprise network is more complex and distributed than ever before. New security challenges arise weekly. The evolving threat landscape, along with growing trends such as cloud computing and the Internet of Things (IoT), further complicate the situation. Maintaining full visibility is increasingly more difficult as you add users and devices to your network.

Network security can go beyond conventional anomaly detection by harnessing the power of network traffic flow data. Real-time situational awareness of all the users, devices, and traffic on your extended network allows you to quickly and effectively respond to threats. You can detect and protect against a wide range of attacks with continuous monitoring and intelligence.

You can help defend your entire organization with views into everything happening across your network, data center, and even your data stored in public clouds. Threats don’t only come from outside the network anymore. Stolen credentials or other techniques make it necessary to monitor more than just the perimeter or even just your network.

Cisco Stealthwatch

Cloud Network Solutions recommends Cisco Stealthwatch, which aggregates and analyzes network telemetry, information generated by network devices, to turn your network into a sensor. You gain visibility into system traffic flows from the network edge to the data center, including virtual machines. Stealthwatch detects a wide range of network and data center issues, from malicious insiders attempting to exfiltrate sensitive data to malware spreading internally from host to host. It works with the entire Cisco router and switch portfolio as well as a variety of security solutions, all available through Cloud Network Solutions, including:

  • Cisco Secure Data Center
  • Cisco IOS Flexible NetFlow
  • Cisco TrustSec security technology
  • Cisco ASA with FirePOWER Services Next-Generation Firewalls (NGFWs)
  • Cisco Identity Services Engine (ISE)
  • Cisco Web Security Appliance (WSA)
  • Cisco Security Packet Analyzer

Cisco Stealthwatch Advantage

Stealthwatch uses network data to accelerate and improve anomaly detection, incident response, and forensics across your entire network. It establishes a baseline of what’s considered normal behavior and activity on your network. With this baseline as your primary reference point, you can use the solution to identify anomalous behavior on your network that may signify an attack. The proposed solution leverages traffic flows to monitor your entire environment to determine whether policy and network access violations are taking place.

The proposed solution continuously monitors both north-south and east-west traffic inside your network to identify traffic patterns that may signal system abuse and insider threats. This allows you to help identify and defend against zero-day malware, advanced persistent threats (APTs), DDoS attempts, and other attacks before they cause harm. The proposed solution’s Stealthwatch Management Console enables you to view and monitor these traffic flows for anomaly detection.

These are the primary features of Stealthwatch:

  • Deep visibility across the network perimeter, interior, data center, and private and public cloud
  • Simplified understanding of normal network behavior through the use of NetFlow
  • Continuous monitoring of devices, applications, and users throughout your distributed networks
  • In-depth forensic investigations and post-incident response with contextual threat intelligence and detailed, historic audit trails of NetFlow data
  • Easy integration with your existing network infrastructure (compatible with non-Cisco telemetry), Cisco Security Packet Analyzer, Cisco ASA Firewalls, Cisco ISE, Cisco TrustSec technology-supported hardware, and a variety of other security solutions, all available through Cloud Network Solutions .
