How to create and customize DPI signatures for R&S®PACE 2
Deep packet inspection (DPI) analyzes evolving network traffic. However, to ensure that existing DPI libraries meet the needs of users with niche or propietary applications, it is necessary that users are able to define and add custom signatures to the existing repository, based on their current requirements. The custom service classifier (CSC) plug-in by ipoque enables the creation of custom signatures using JSON. It grants flexibility and independence to curate a unique library, enriching network intelligence and meeting monitoring needs. R&S®PACE 2

Handling Log4j security vulnerabilities with deep packet inspection
Log4j is a library used by Java developers to record or log network events. However, recently it has come to light that Log4j allows for significant security breaches and attacks. Log4j security vulnerabilities have taken the IT world by storm. A simple email message can be manipulated to instruct Log4j to leak critical data over the Internet, execute crypto mining and launch ransomware. DPI can stave off such threats by offering real-time detection of Log4jShell exploits and the real-time identification of consequential attacks on the system.

Reinstating cloud visibility with deep packet inspection
Deep packet inspection software delivers cloud visibility by equipping analytics intermediaries with application awareness which can be used to select and forward cloud traffic to a wide range of monitoring, security and network management tools. For distributed applications hosted and delivered from different clouds, the analysis provided by R&S®PACE 2 ensures that no gaps are left unattended in managing and delivering critical applications. Likewise, R&S®PACE 2 enables further optimization of cloud security management by coupling inspection of traffic anomalies with application awareness.

How next-gen DPI addresses the shortcomings of SSL/TLS inspection
Decryption using SSL/TLS inspection is admittedly the simplest method to address the loss of traffic visibility due to encryption. Deciphering the payload information provides all the prerequisite information at the packet level, allowing network administrators to manage and secure traffic flows effectively and efficiently. This article highlights the shortcomings of SSL/TLS. It discusses how next-gen DPI, equipped with encrypted traffic intelligence (ETI) addresses these limitations by combining advanced techniques such as machine learning, deep learning and advanced caching.
