Agent skill

implementing-syslog-centralization-with-rsyslog

Configure rsyslog for centralized log collection with TLS encryption, custom templates, and log rotation. Generates server and client configuration files with GnuTLS stream drivers, x509 certificate authentication, per-host log segregation, and reliable queue settings for high-availability syslog infrastructure.

Instructions

  1. Install dependencies: pip install jinja2 paramiko
  2. Generate TLS certificates for rsyslog server and clients using OpenSSL.
  3. Run the agent to generate rsyslog server and client configurations:
    • Server: TLS listener on port 6514, per-host directory output, JSON-format templates
    • Client: TLS forwarding with disk-assisted queues for reliability
  4. Deploy configurations to servers via SSH (paramiko).
  5. Validate TLS connectivity and log delivery.
bash
python scripts/agent.py --server-ip 10.0.0.1 --clients 10.0.0.10,10.0.0.11 --ca-cert ca.pem --output syslog_report.json

Examples

Server Configuration (TLS)

module(load="imtcp" StreamDriver.Name="gtls" StreamDriver.Mode="1"
       StreamDriver.Authmode="x509/name")
input(type="imtcp" port="6514")
template(name="PerHostLog" type="string" string="/var/log/remote/%HOSTNAME%/%PROGRAMNAME%.log")
*.* ?PerHostLog

Client Configuration (Reliable Forwarding)

action(type="omfwd" target="10.0.0.1" port="6514" protocol="tcp"
       StreamDriver="gtls" StreamDriverMode="1"
       StreamDriverAuthMode="x509/name"
       queue.type="LinkedList" queue.filename="fwdRule1"
       queue.maxdiskspace="1g" queue.saveonshutdown="on"
       action.resumeRetryCount="-1")

mapping-mitre-attack-techniques

Maps observed adversary behaviors, security alerts, and detection rules to MITRE ATT&CK techniques and sub-techniques to quantify detection coverage and guide control prioritization. Use when building an ATT&CK-based coverage heatmap, tagging SIEM alerts with technique IDs, aligning security controls to adversary playbooks, or reporting threat exposure to executives. Activates for requests involving ATT&CK Navigator, Sigma rules, MITRE D3FEND, or coverage gap analysis.
