Unlocking the Potential of AI/ML in Cybersecurity: Challenges, Opportunities, and Progress Indicators

Artificial intelligence (AI) has been transforming the cybersecurity landscape for over a decade, with machine learning (ML) speeding the detection of threats and identifying anomalous user and entity behaviors. However, recent developments in large language models (LLMs), such as OpenAI’s GPT-3, have brought AI to the forefront of the cybersecurity community. These models use documented …

Extended detection and response

XDR will converge from different directions: XDR, Open XDR, Native XDR, Hybrid XDR -> XDR

2022 Predictions By Aimei Wei Initial definitions of XDR envisioned eXtended Detection and Response – a single platform that unified detection and response across the entire security kill chain. According to Rik Turner, who coined the XDR acronym, XDR is “a single, stand-alone solution that offers integrated threat detection and response capabilities.”  To meet Omdia’s …

Why Network Detection and Response (NDR) ? See the Entire Elephant in the Room

Network detection and response (NDR) has a long history, evolving out of network security and network traffic analysis (NTA). The historical definition of network security is to use a perimeter firewall and Intrusion Prevention System (IPS) to screen traffic coming into the network, but as IT technology and security technology have evolved due to modern …

SIEM security

SIEM, XDR, and the Evolution of Cybersecurity Infrastructure

Security Event and Information Management platforms (SIEMs) collect data from security logs and in doing so are supposed to identify blind spots, reduce noise and alert fatigue, and simplify detection and response to complex cyberattacks. However, SIEMs have not lived up to these promises. Now, the new idea is XDR – what are its advantages, …

NDR vs. Open XDR – What’s the difference?

Every security tool vendor talks about detection and response, so what makes NDR so special, and how does it relate to XDR / Open XDR? NDR is special because it focuses on the nerve center of an organization’s IT infrastructure: the network. Wireless or wired device, endpoint or server, application, user or cloud – all …

How Stellar Cyber Addresses Data Storage Pain

Security problems are essentially data problems. For threat detection, investigation and forensic analysis, ideally one would like to collect as much data as they can and store it as long as they want. However, everything has its limitations. For example, the high long-term storage costs, the slow speed of search/query and infrastructure requirements are common …
