SURICATA(8) System Manager's Manual SURICATA(8)
NAME
suricata - Next Generation Intrusion Detection and Prevention Tool
SYNOPSIS
suricata [options]
DESCRIPTION
suricata is a network Intrusion Detection System (IDS). It is based on rules (and is fully compatible with snort rules) to detect a variety
of attacks / probes by searching packet content.
This new Engine supports Multi-Threading, Automatic Protocol Detection (IP, TCP, UDP, ICMP, HTTP, TLS, FTP and SMB), Gzip Decompression,
Fast IP Matching and coming soon hardware acceleration on CUDA and OpenCL GPU cards.
It supports acquiring packets through NFQUEUE, PCAP (live or offline) etc.
OPTIONS
-c config_file
Use configuration file config_file
-i interface
Sniff packets on interface.
-r file
Read the tcpdump-formatted file tcpdump-file. This will cause Suricata to read and process the file fed to it. This is useful for
offline analysis.
-q queue_id
Sniff packets sent by the kernel through NFQUEUE. This allows running Suricata in inline mode (IPS) for packets captured by iptables
using the NFQUEUE target.
-s signatures
Path to the signatures file.
-l log_dir
Path to the default log directory.
-D Run as daemon
--init-errors-fatal
Enable fatal failure on signature init error.
SEE ALSO
tcpdump(1), pcap(3).
