• Deploy intrusion detection at network boundaries
• Write rules for organization-specific threats
• Reduce noisy or false alerts

Create rules for Suricata and Snort, systems that detect suspicious network traffic, to flag port scans and reconnaissance. Combine packet patterns with connection counts, tune alert volume, and summarize scanning sources, targets, and activity.

• Create rules to detect Nmap and Masscan activity
• Monitor scanning within an internal network
• Tune alerts for authorized vulnerability scanners

Analyze Cobalt Strike communication profiles and Beacon payload configurations to extract request paths, headers, timing, and process injection settings. Turn these indicators into a JSON report and network detection rules for Suricata or Snort.

• Analyzing a captured Malleable C2 profile
• Extracting communication settings from a Beacon payload
• Creating Suricata or Snort detection rules

Writes and validates Suricata/Snort IDS rules for network-based malware detection, covering rule anatomy, content/pcre matching, flow and threshold options, and common mistakes that cause false positives or no matches. Activates for requests to write a Suricata rule, create Snort signatures, or build network detection rules from IOCs or C2 patterns.

IDS/IPS detection content for a CVE — Snort/Suricata-compatible rules, YARA signatures, ProjectDiscovery Nuclei templates, traffic-filter rules. Capability-aware: skips families when the binary is not installed (no Snort = no Snort output). Use when deploying defences for a CVE without a patch, augmenting SAST with active detection, or feeding the SOC engineering pipeline.
