    * Assessing Internet Security Risk, Part Four: Custom Web
    October 4th, 2002
    This article is the fourth in a series that is designed to help readers to
    assess the risk that their Internet-connected systems are exposed to. In
    the first installment, we established the reasons for doing a technical
    risk assessment.
    * Apache 1.3.27 Released: Fixes Multiple Security Vulnerabilities
    October 4th, 2002
    This version fixes multiple security vulnerabilities including a SysV a
    SysV shared memory-based scoreboards attack, a XSS vulnerability in the
    default 404 page handling hosted on a domain that allows wildcard DNS
    lookups, and some possible overflows in ab.c which could be exploited by a
    malicious server.
    * Creating an Anonymous FTP server with Publicfile
    October 2nd, 2002
    For many moons I've meant to set up an FTP server for stunnel.org. Not
    because I like FTP, but because there are times even I find myself without
    a web browser of any kind. The server needs to support anonymous FTP (ftp
    without a password) and doesn't need to have the ability for anyone to
    have 'real' logins.
    * Unix tools track hackers
    October 1st, 2002
    In forensic analysis, you cannot use any tools that are currently
    installed on the hacked system, because those tools could have been
    replaced with Trojan programs. For example, the ps program that displays
    the process table could have been replaced with a Trojan ps program that
    displays everything except the process of a running hacker daemon.

    * The Twenty Most Critical Internet Security Vulnerabilities
    October 3rd, 2002
    The majority of the successful attacks on operating systems come from only
    a few software vulnerabilities. This can be attributed to the fact that
    attackers are opportunistic, take the easiest and most convenient route,
    and exploit the best-known flaws with the most effective and widely
    available attack tools.
    * Introduction to netfilter/iptables
    October 2nd, 2002
    The netfilter/iptables is the IP packet filtering system that is
    integrated with the latest 2.4.x versions of the Linux kernel. This system
    facilitates greater control over IP packet filtering and firewall
    configuration on Linux systems, be they systems connected to the Internet
    or a LAN, servers, or proxy servers interfacing between a LAN and the
    * Evaluating Network Intrusion Detection Signatures, Part Two
    October 2nd, 2002
    In this series of articles, we present recommendations that will help
    readers to evaluate the quality of network intrusion detection (NID)
    signatures, either through hands-on testing or through careful
    consideration of third-party product reviews and comparisons.

    * Scientists Find Key To Water-Tight Encryption
    October 3rd, 2002
    UK researchers have managed to send untamperable encryption keys over long
    distances, opening the way for totally secure communications.  A team of
    scientists said on Wednesday they had made a major leap toward developing
    secure global communications.

    and IT Directors in European companies with more than 200 employees.
