Loginlog
A small program that watches the wtmp file and reports all logins to
the syslogd.

logsurfer version 1.5a
The logsurfer program is a tool to monitor arbitrary logfiles (for
example syslog-messages), automatically anaylse them and invoke actions.

NfsWatch
NFSWatch lets you monitor NFS requests to any given machine, or the
entire local network. It mostly monitors NFS client (NFS requests);
it also monitors the NFS reply traffic from a server in order to measure
the response time for each RPC.

Network Intrusion Detector version 2.4
Network Intrusion Detector (NID) is a suite of software tools that helpsi
detect, analyze, and gather evidence of intrusive behavior occurring on
an Ethernet or Fiber Distributed Data Interface (FDDI) network using the
Internet Protocol (IP). NID operates passively on a stand-alone host (rather
than residing on the hosts it is monitoring), and is responsible for
collecting data and/or statistics about network traffic.
Download:
http://ciac.llnl.gov/cstc/nid/nid.html
NOCOL version 4.3.1
NOCOL/NetConsole (Network Operation Center On-Line) is a network
monitoring package that runs on Unix platforms and capable of monitoring
network and system variables such as ICMP or RPC reachability, RMON
variables, nameservers, ethernet load, port reachability, host performance,
SNMP traps, modem line usage, appletalk & novell routes/services, BGP peers,
etc. The software is extensible and new monitors can be added easily.

NoShell
This program is designed to provide the system administrator with additional
information about who is logging into disabled accounts. Traditionally,
accounts have been disabled by changing the shell field of the password
entry to "/bin/sync" or some other benign program. Noshell provides an
informative alternative to this method by specifying the noshell program as
the login shell in the password entry for any account which has been
disabled.

NTLast
A Win32 command line security audit tool.

SABERNET NTsyslog
This program runs as a service under Windows NT 4.0. It formats all System, Security, and Application events into a single line and sends them to a syslog(3) host (centralised logs).
Download:

Psionic PortSentry
PortSentry is part of the Abacus Project suite of security tools. It is a
program designed to detect and respond to port scans against a target host
in real-time. Most known port-scan methods are detected, including
SYN/half-open, DIN, NULL, X-MAS, and oddball packet scans.

http://www.psionic.com/abacus/portsentry/
scan-detector
Scan-detector is a simple detector for automated scans of TCP/UDP ports on
a host (written in Perl v5).
Download:
http://www.ja.net/CERT/Software/scan-detector/
Scanlogd
A very effective port scan detector.
Download:
http://www.openwall.com/scanlogd/
Sentry
Sentry will detect any connection made to a TCP or UDP port on your host
that you tell it to listen to. A configuration file can be made to have it
listen to dozens of ports at once to detect anything from a full-fledged
sequential port sweep to a random port probing. Because it covers the UDP
spectrum as well it will alert you to people probing for RPC services
surreptitiously as well as TFTP, SNMP, etc.

Snort
Snort is an open source network intrusion detection system, capable of
performing real-time traffic analysis and packet logging on IP networks. It can
perform protocol analysis, content searching/matching and can be used to detect
a variety of attacks and probes, such as buffer overflows, stealth port scans,
CGI attacks, SMB probes, OS fingerprinting attempts, and much more.

SWATCH version 2.2
SWATCH (The Simple WATCHer and filter) monitors log files such as syslog
which allows an administrator to take specific actions, such as sending an
email warning, in response to logged events.
Download:
http://www.ja.net/CERT/Software/SWATCH/
TCP Wrapper
TCP Wrapper provides monitoring of incoming connections to various network
services (started by the inetd program or similar). It also provides access
control to limit the address of machines that can connect to the system,
remote username lookup (using RFC 931 protocol), and protection against
machines that pretend to have someone else's host name.

internetwork Firewalls. It is distributed in source code form, with all modules
written in the C programming language and runs on many BSD UNIX derived
platforms.

ttywatcher
TTY-Watcher is a utility to monitor and control users on a single system. It
is based on our IP-Watcher utility, which can be used to monitor and control
users on an entire network (For more information about this utility, see
http://nad.infostructure.com/watcher.html). TTY-Watcher is similar to
advise or tap, but with many more advanced features and a user friendly
(either X-Windows or text) interface.
