Introduction to atapost.pl
atapost.pl is a Perl-based network traffic analysis tool developed under Cisco’s Q2 2025 Network Automation Initiative. Designed for enterprise network administrators, this utility processes NetFlow/IPFIX data streams to generate actionable insights for traffic engineering and security monitoring. The software implements RFC 7011-7015 standards while adding Cisco-proprietary enhancements for deep packet inspection.
Key functionalities include:
- Automated traffic pattern recognition across ASR 9000/Nexus 9000 platforms
- Real-time DDoS attack signature detection
- BGP flow specification (Flowspec) rule generation
- Compliance with ISO/IEC 27037 digital evidence preservation standards
Key Features and Improvements
-
Enhanced Traffic Forensics
- Zero-day attack pattern recognition using neural network models
- Integrated NetFlow v9-to-IPFIX conversion engine
-
Performance Optimization
- 40% faster processing of 10M+ flow records compared to v13.2
- Multi-threaded architecture supporting 64-core systems
-
Security Enhancements
- TLS 1.3 encrypted flow metadata handling
- Automated CVE-2025-2281 mitigation ruleset generation
-
Protocol Support
- Full dissection of QUIC v2/HTTP3 payloads
- Enhanced MPLS VPN traffic classification (RFC 4364 compliance)
