Network Security

High-speed network proliferation coupled with evolving dynamic nature of network environments opens up challenges specifically with respect to Network Security. Globally networks face serious threats due the sophistication of attacks and malicious behaviours.
Aspects such as high-speed connectivity and dynamic configuration of nodes, wider ranges of services, on-the-fly entries and exits of mobile nodes, virtualization and changes to operating systems and applications pose security related challenges.

CDAC is involved in addressing research challenges in the field of Network and System Security. Based on the support from the Government of India, CDAC team is focussing on the following specific areas:


1. GYN (Guard Your Network) Intrusion Detection /Prevention System:

GYN is a Network Intrusion Detection / Prevention Appliance developed by C-DAC. GYN shall work in bridge mode (in-line) for providing protection. It analyzes the packets to take preventive measures after validating the critical attacks by carrying out multi-method detection using SNORT compatible signatures and anomaly detection mechanism.
GYN Analyzer capabilities include analysis of packets and network flow records with user friendly web-based Management facility. Internal Architecture of GYN includes Signature based protection and flow based anomaly detection. It also provides comprehensive threat analysis.

2. CHAKRA- Dynamic Firewall.

Chakra is a powerful, flexible and feature rich network based dynamic firewall solution. Apart from having regular firewall features like traffic filtering, Chakra also provides unique functionalities like dynamic rule generation through network traffic monitoring, analysis and alert correlation. Chakra collects, analyze and correlate the outputs from multiple network monitoring sources like SNMP, network flow and IDS to generate dynamic firewall rules. Chakra can generate and configure firewall rules automatically for attack which change the traffic pattern of network such as DoS, DDoS, flood etc. It is capable to generate flexible reports related to traffic trend, security events and alerts. Chakra provides the flexibility and control over firewall for monitoring, configuration and management in critical attack scenarios through an interactive web based interface.
