XCOL: xApp-based Framework for Detecting Layer-2 DoS Attacks in 5G NR
Arpit Tripathi, Abdulla Ovais, Bheemarjuna Reddy Tamma, Abhishek Thakur
The growing adoption of 5G in industrial deployments expands the attack surface for adversarial exploitation. Fake Base Stations (FBSs), which lure benign UEs in a fake attach procedure, and Malicious …
FALCON++: A Semi-Supervised Anomaly Detection and Localization Framework for Resilient O-RAN Deployments
Yaswanth Kumar LS, Somya Jain, Michael Suguna Kumar Victor, Abdulla Ovais, Suresh Kumar Amalapuram, Bheemarjuna Reddy Tamma, Siva Ram Murthy C
Fault detection is a critical problem in Open Radio Access Network (O-RAN) observability, but the availability of labeled fault data is extremely limited, and enumerating all possible fault scenarios is …
Demo: A Drift-Handling Automation in AI/ML Framework Integrated O-RAN
Venkatesh Gani, Dhruv, Yaswanth Kumar L. S., Ashit Subudhi, Majid K, Abhishek Bhattacharyya, Venkateswarlu Gudepu, Bheemarjuna Reddy Tamma, Koteswararao Kondepu
Beyond 5G (B5G) networks increasingly leverage open and disaggregated Radio Access Networks (O-RAN) to enable high-speed, low-latency, and flexible services across diverse use cases. However, the dynamic nature of user …
Denial of Service Attacks Targeting Layer 2 in 5G RAN
Arpit Tripathi, Ashutosh Rajput, Ashit Kumar Subudhi, Koteswararao Kondepu, Abhishek Thakur, Bheemarjuna Reddy Tamma
Denial of Service (DoS) attacks on legitimate users using a Fake Base Station (FBS) remain a persistent threat to the integrity and reliability of 5G networks. These attacks exploit gaps …
Building a Security Canopy Over O-RAN: The SDP Paradigm
Antony Franklin, Tejas Sameer Deshmukh
The Open Radio Access Network (O-RAN) architecture provides flexibility in the deployment of RAN, but introduces significant security vulnerabilities due to its open interfaces and disaggregated nature, expanding the attack …
Methods and Systems for Privacy-Preserving Federated Continuous Internet Forensics
Maruthi Seshidhar Inukonda, Jessy Bondla, Bheemarjuna Reddy Tamma, Sparsh Mittal
FALCON: A Framework for Fault Prediction in Open RAN Using Multi-Level Telemetry
Bheemarjuna Reddy Tamma, , Koteswararao Kondepu, Yaswanth Kumar L S
Open Radio Access Network (O-RAN) has brought in deployment flexibility and intelligent RAN control for mobile operators through its disaggregated and modular architecture using open interfaces. However, this disaggregation introduces …
HiPer : An XDR Solution for High Performance Compute Clusters using Zeek and Wazuh
Bheemarjuna Reddy Tamma, Priyanka Narang, Abhinav Yadav, Maruthi S. Inukonda
Internet connectivity in high performance computing (HPC) systems like national super-computing facilities increase the risk of security threats. This paper presents HiPer, an end-to-end extended detection and response (XDR) solution, …
SMART-RIC6G: Smart Drift-Handling Enabler for RAN Intelligent Controllers in 6G Networks
Venkatesh Gani, Dhruv, Yaswanth Kumar L.S., Ashit Subudhi, Majid K, Abhishek Bhattacharyya, Venkateswarlu Gudepu, Bheemarjuna Reddy Tamma, Koteswararao Kondepu
This work demonstrates a real-time drift detection, analysis, and adaptation by leveraging an AI/ML framework integrated O-RAN. This is achieved with real time data collection from open interfaces which would …
LAMP: A latency-aware MAC protocol for joint scheduling of CAM and DENM traffic over 5G-NR sidelink
Suranjan Daw, Anwesha Kar, Venkatarami Reddy Chintapalli, Bheemarjuna Reddy Tamma, Siva Ram Murthy C.
Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs) are two types of messages used in Intelligent Transport Systems (ITS) for Vehicle-to-Everything (V2X) communication. CAMs are used to periodically …
SPIDER: A semi-supervised continual learning-based network intrusion detection system
Amalapuram Suresh Kumar, Bheemarjuna Reddy Tamma, Sumohana S Channappayya
