Cyber Defenders Defending Critical Infrastructure Interview with Aaron Cockerill

Nextgov interview with Aaron Cockerill for a conversation shaped by today’s topics of critical infrastructure and cybersecurity threats. Discussing everything from phishing attacks to hybrid-remote work best practices, this interview offers insight into how Lookout can help both public and private organizations address digital threat prevention, providing relevant context to the cybersecurity world going forward.

SANSFire: An Alert Has Fired. Now what?

While the security industry spends a lot of time and energy getting more and/or better alerts, comparatively little investment has gone into helping analysts operationalize and contextualize those alerts. This webcast will discuss how a solid foundation of network telemetry can enable not only high-velocity, high-confidence processing of alerts of all stripes, but also a host of other critical security applications, from fundamentals like asset management to advanced techniques like proactive threat hunting. Real-world examples and code will be used throughout the talk, along with practical considerations for operating in an enterprise environment.

Detect security threats with anomaly detection rules

Securing your environment requires being able to quickly detect abnormal activity that could represent a threat. But today’s modern cloud infrastructure is large, complex, and can generate vast volumes of logs. This makes it difficult to determine what activity is normal and harder to identify anomalous behavior. Now, in addition to threshold and new term –based Threat Detection Rules , Datadog Security Monitoring provides the ability to create anomaly

Why social graphs won't save you from account takeover attacks

Account takeover (ATO) is a dangerous form of business email compromise (BEC). Attackers gain access to a legitimate email account within an organisation, often by stealing credentials through spear phishing. They’ll then send emails from the compromised account with the goal of getting a fraudulent payment authorised or accessing sensitive data to exfiltrate.

Detecting Security Threats: How to Set up Alerts and Prevent Threats?

Detecting and preventing security threats is a lot easier than fixing already existing ones. With this in mind, you should set up alerts to detect security threats before they occur and do your best to prevent them from happening. There are many ways to set up security alerts. One way to set up alerts is to use a SIEM system such as LogSentinel SIEM, which will send you an alert if something suspicious happens. This way, for example, if you notice a potential security breach, you can turn off your system network in order to prevent the hacker from accessing your network.

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.
