3 Advantages of Outsourced Network Monitoring
There are multiple advantages of outsourced networking monitoring. No matter your organization’s size, it’s vitally important to protect the data that can be accessed inside and outside of the perimeter.

The Latest Cybersecurity News & Insights From Around The World
Corelight Smart PCAP
Security teams can save up to 10x the packet retention period at 50% the cost compared to full packet capture! Sounds too good to be true, right? It’s not! With powerful, yet easy-to-use pcap levers we let security teams capture just the packets needed for investigations, and correlate them with our alerts and logs, and make packets 1-click retrievable. With Smart PCAP you get months, not days' worth of packet visibility.
How to Spot C2 Traffic on Your Network
Attackers often hide their command and control (C2) activity using techniques like encryption, tunneling in noisy traffic like DNS, or domain generation algorithms to evade blacklists. Reliably spotting C2 traffic requires a comprehensive network security monitoring capability like open source Zeek that transforms packets into connection-linked protocol logs that let analysts make fast sense of traffic. Corelight’s commercial NDR solutions generate this Zeek network evidence and also provide dozens of proprietary C2 insights and detections.

Encrypted Traffic Collection
Working with encrypted traffic is a common task in the SOC and one that many people think network monitoring solutions can't do anything about. The reality, however, is a bit less cut and dry than you might think. Corelight with Zeek can parse details about the certificate handshake and the SSL connection itself. See the cipher and elliptic curve in use, which are great for detecting vulnerabilities like CurveBall. Learn more about Corelight's Encrypted Traffic collection in this brief two minute video.
Accelerate SecOps with a Single Source of Network Truth
Network evidence is vital for defense, but collecting it can be overly complicated and result in incomplete data that is difficult to use. By transforming VPC and on-premises traffic into Zeek logs and Suricata alerts, you can accelerate threat hunting and incident response workflows in security analytics tools like Chronicle and VirusTotal.
How Network Segmentation Can Protect Supply Chains from Ransomware Attacks
Organizations can take various steps to protect their operational technology (OT) environments against digital threats. But some stand out more than others. In particular, network segmentation is described as “the first answer to insufficient ICS (Industrial Control System) cybersecurity.” Experts advocate zoning ICS assets to coordinate informational technology (IT) and OT environments effectively. That doesn’t always happen, however.
What is edge networking? An overview on the network edge
As organizations look for ways to improve network performance for user-facing application data, it is becoming increasingly evident that routing requests all the way to internal data centers is the least optimized model. Doing so increases latency, reduces available bandwidth, increases bandwidth requirements at the data center, and increases overall costs.

Compromising a Network Using an "Info" Level Finding
Anyone who has ever read a vulnerability scan report will know that scanners often include a large number of findings they classify as "Info". Typically this is meant to convey general information about the target systems which does not pose any risk. Many people who read such reports will generally ignore all of the "Info" findings, and focus only on anything labeled "Critical" or "High". However, this can be dangerous for a number of reasons.
