Syslog Intelligence — GlideHubAi

Architecture

Enterprise log management
at scale

GlideHubAi's syslog module uses a high-performance collection and forwarding engine trusted by enterprise deployments worldwide. We extend it with a modern parsing pipeline, AI-driven analysis layer, and tight integration with the rest of the platform.

Multi-Source Log Collection

UDP/TCP Syslog — RFC 3164 (legacy) and RFC 5424 (structured syslog) on ports 514 UDP, 514 TCP, and 6514 TLS.
TLS-encrypted transport — RELP (Reliable Event Logging Protocol) with imrelp — guaranteed delivery, no dropped messages even during network disruptions.
File monitoring — imfile module monitors log files on disk with inotify for real-time tailing — ideal for application logs that don't emit syslog.
Windows Event Log — WinRM-based collection of Windows Security, Application, and System event logs normalized to syslog format.
Beats/Logstash — Accept Elastic Beats (Filebeat, Winlogbeat) and Logstash JSON forwarding for hybrid environments.
Cloud logs — AWS CloudTrail, Azure Monitor, GCP Cloud Logging ingested via API polling with normalization.
Network device syslogs — Cisco, Juniper, Fortinet, Palo Alto log forwarding with vendor-specific message parsers (facility/severity mapped).

Log Parsing & Normalization

High-performance field extraction — liblognorm-based parsing engine extracts structured fields from thousands of log formats using RuleBase definitions — no regex overhead at scale.
Vendor parsers — Pre-built parsers for Cisco ASA, PIX, IOS; Juniper SRX; Palo Alto PAN-OS; Fortinet FortiOS; Windows Event XML.
Custom RuleBases — Define your own liblognorm rules for proprietary application logs using a simple line-annotation syntax.
Field enrichment — Automatic enrichment: GeoIP lookup (MaxMind), hostname→asset lookup, WHOIS data for external IPs.
ECS normalization — Output normalized to Elastic Common Schema (ECS) fields for compatibility with Elasticsearch/Kibana downstream.
CEF / LEEF support — Parse ArcSight CEF and QRadar LEEF formats for SIEM migration or hybrid deployments.

Threat Detection Rules

MITRE ATT&CK mapping — 300+ detection rules mapped to MITRE ATT&CK tactics and techniques with severity scoring.
Brute force detection — Count-based correlation: X failed auth attempts from same source IP within Y seconds → HIGH severity alert.
Privilege escalation — Pattern-match for sudo, su, UAC bypass, and Windows token manipulation events.
Data exfiltration signals — Unusual outbound data volumes detected by correlating syslog with netflow data.
Anomaly detection — AI baseline learns normal log patterns per host; alerts on deviations (e.g. unusual login hour, first-time access to sensitive file).
Threat intelligence feeds — Real-time lookups against AlienVault OTX, Shodan, and custom STIX/TAXII feeds for known-bad IPs and domains.

Automated Response Actions

IP blocking — Push firewall deny rules to Cisco ACL, Palo Alto Security Policy, or iptables on detection of malicious source IP.
Account disable — AD/LDAP integration to disable compromised accounts automatically when credential abuse detected.
Session termination — Kill active SSH/RDP sessions flagged as suspicious via API calls to target systems.
Trigger backup — Detected config change in syslog → immediately trigger configuration backup and diff analysis.
Ticket creation — Auto-generate security incidents in ServiceNow, Jira, or Freshservice with full log context attached.
SOAR integration — Push enriched alerts to Splunk SOAR, Palo Alto XSOAR, or IBM Resilient for advanced orchestration.
