PGP (Pretty Good Privacy) is a public key encryption pack-
age to protect E-mail and data files. It lets you commu-
nicate securely with people you've never met, with no
secure channels needed for prior exchange of keys. It's
well featured and fast, with sophisticated key management,
digital signatures, data compression, and good ergonomic
design.
OSSEC is an Open Source Host-based Intrusion Detection System.
It performs log analysis, integrity checking, Windows registry
monitoring, rootkit detection, time-based alerting and active
response.
from the README:
OutGuess is a universal steganographic tool that allows the insertion
of hidden information into the redundant bits of data sources. The
nature of the data source is irrelevant to the core of OutGuess. The
program relies on data specific handlers that will extract redundant
bits and write them back after modification. In this version the PNM
and JPEG image formats are supported.
The histogram utility is not installed by this port/package because
it crashes.
Bro is an open-source, Unix-based Network Intrusion Detection System (NIDS)
that passively monitors network traffic and looks for suspicious activity.
Bro detects intrusions by first parsing network traffic to extract its
application-level semantics and then executing event-oriented analyzers that
compare the activity with patterns deemed troublesome. Its analysis includes
detection of specific attacks (including those defined by signatures, but
also those defined in terms of events) and unusual activities (e.g., certain
hosts connecting to certain services, or patterns of failed connection
attempts).
Bro is documented in the USENIX 1998 Security Conference proceedings.
BASE is the Basic Analysis and Security Engine. It is based on the code
from the ACID project. This application provides a PHP-based web front-end
to query and analyze the alerts coming from a Snort IDS system.
BASE is a web interface to perform analysis of intrusions that Snort has
detected on your network. It uses a user authentication and role-base
system, so that you as the security admin can decide what and how much
information each user can see. It also has a simple to use, web-based
setup program for people not comfortable with editing files directly.
BitDefender Console Antivirus
ccsrch is a tool that searches for and identifies unencrypted and
contiguous credit card numbers (PAN) and track data on Windows and
UNIX operating systems. It will also identify the location of the
PAN data in the files and record MAC times.
An ncurses based password database client that is compatible
with KeePass 1.x format databases.
Clamassassin is a simple virus filter wrapper for ClamAV for use in procmail
filters and similiar applications. Clamassassin's interface is similiar to
that of spamassassin, making it easy to implement for those familiar with
that tool. Clamassassin is designed with an emphasis on security, robustness
and simplicity.
