Deep packet inspection | Breaking Cybersecurity News | The Hacker News

Today, most Network Detection and Response (NDR) solutions rely on traffic mirroring and Deep Packet Inspection (DPI). Traffic mirroring is typically deployed on a single-core switch to provide a copy of the network traffic to a sensor that uses DPI to thoroughly analyze the payload. While this approach provides detailed analysis, it requires large amounts of processing power and is blind when it comes to encrypted network traffic. Metadata Analysis has been specifically developed to overcome these limitations. By utilizing metadata for analysis, network communications can be observed at any collection point and be enriched by the information providing insights about encrypted communication. Network Detection and Response (NDR) solutions have become crucial to reliably monitor and protect network operations. However, as network traffic becomes encrypted and data volumes continue to increase, most traditional NDR solutions are reaching their limits. This begs the question: What detect

Governments in Turkey and Syria have been caught hijacking local internet users' connections to secretly inject surveillance malware, while the same mass interception technology has been found secretly injecting browser-based cryptocurrency mining scripts into users' web traffic in Egypt. Governments, or agencies linked to it, and ISPs in the three countries are using Deep Packet Inspection technology from Sandvine (which merged with Procera Networks last year), to intercept and alter Internet users' web traffic. Deep packet inspection technology allows ISPs to prioritize, degrade, block, inject, and log various types of Internet traffic, in other words, they can analyze each packet in order to see what you are doing online. According to a new report by Citizen Lab, Turkey's Telecom network was using Sandvine PacketLogic devices to redirect hundreds of targeted users (journalists, lawyers, and human rights defenders) to malicious versions of legitimate progra

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic
