time for each RPC.

Intrusion Detector |
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.

Operation Center On-Line |
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.

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.

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).

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.

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/
A very
effective port scan detector.
Download:
http://www.openwall.com/scanlogd/
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.

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:

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.

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.
