But he can't. His law enforcement agency in Louisiana lacks the money and manpower to guard an entire network, so instead he looks for less expensive options--free ones, actually. http://www.linuxsecurity.com/articles/server_security_article-5105.html * Anti-virus/anti-spam mail server setup using MailScanner June 6th, 2002 Wouldn't it be great to have the ability to stop email-borne virus traffic, arguably the most ubiquitous kind, at the server level where you control the action? If this idea appeals to you, read on. http://www.linuxsecurity.com/articles/server_security_article-5098.html * Enhancing E-Mail Security With Procmail June 5th, 2002 Welcome to the home page of the Procmail Email Sanitizer. The Sanitizer is a tool for preventing attacks on your computer's security via email messages. It has proven to be very effective against the latest crop of Microsoft email worms that have gotten so much attention in the popular press. http://www.linuxsecurity.com/articles/server_security_article-5093.html * Aide 0.9 Released June 4th, 2002 The most common type of hacker simulation is a remote scan of a company's network, which gives the target company an idea of what its networks look like to a hacker on the Internet. The cost of worldwide intellectual property theft, much of which occurs as a result of corporate espionage conducted through the Internet, may be as high as US$300 billion per year, according to industry watchers. http://www.linuxsecurity.com/articles/intrusion_detection_article-5084.html * Writing PAM Modules, Part Three June 3rd, 2002 PAM stands for Pluggable Authentication Modules and is a system for providing application independence for authentication. A PAM-enabled application calls a stack of PAM modules to run authentication, open and close sessions, and check account validity. http://www.linuxsecurity.com/articles/server_security_article-5077.html +------------------------+ | Network Security News: | +------------------------+ * Monitoring Linux firewalls with firelogd June 7th, 2002 Monitoring firewalls on a Linux system can be a challenge because of the text-based nature of the OS. The firelogd program can greatly improve the monitoring process by e-mailing concise summaries of important entries to an admin. http://www.linuxsecurity.com/articles/firewalls_article-5099.html * IDS at the Crossroads June 7th, 2002 Four infosec innovators size up new threats and how IDSes are evolving to meet them. Gleichauf, Klaus, Ranum and Roesch are interviewed in this article. Intrusion detection is on the minds of many folks. How are threats evolving today? http://www.linuxsecurity.com/articles/intrusion_detection_article-5103.html * The Scanner Tarpit HOWTO June 6th, 2002 How to configure a Linux firewall protecting a publicly-accessible (boundary, DMZ) network to detect worms' and attackers' scanning activity and react in real time to block and interfere with that scanning activity. A discussion of reporting tools and possible extensions is also included. http://www.linuxsecurity.com/articles/documentation_article-5096.html +------------------------+ | Vendors/Products: | +------------------------+ * EnGarde Secure Linux walks away with Editor's Choice, Beats HP, Immunix June 8th, 2002 EnGarde walked away with our Editor's Choice award thanks to the depth of its security strategy, which covers nearly all the bases. Everything from the low-level mechanisms (binary integrity checking and stack protection) to high-level usability issues (including an excellent patching interface) demonstrate the serious effort the Guardian Digital crew has invested in EnGarde. http://www.linuxsecurity.com/articles/vendors_products_article-5106.html * EnGarde Secure Linux Review Wins Perfect Score June 6th, 2002 Guardian Digital's Engarde Secure Linux Professional offers a lightweight, robust, and secure Linux Distribution for small and large networks. This distribution is really great for small to large business. Ease of administration and added security means less man hours. The home business user would appreciate its completeness, ease of use, and its low cost. http://www.linuxsecurity.com/articles/server_security_article-5097.html +------------------------+ | General: | +------------------------+ * An Idea To Can the Spam June 7th, 2002 The problem is that filters do not always prevent mail from bad sources, and the whole "opt-in" farce has resulted in spammers sending whatever messages they want. Yahoo, MSN and many other free (and even paid) e-mail services seem to be repositories for spammers. Even when customers pony up dollars for better accounts, the results are often the same. http://www.linuxsecurity.com/articles/server_security_article-5100.html * Is Linux Ready for National Security? June 5th, 2002 The popularity of the Linux open source operating system is exploding in the public sector, both in the U.S. and abroad. In May, IBM Corp. alone announced a deal to supply the Air Force, Department of Defense (DoD), Department of Agriculture, Department of Energy, and Federal Aviation Administration (FAA) with Linux systems. http://www.linuxsecurity.com/articles/government_article-5092.html * Privacy vs. Security: A Bogus Debate? June 5th, 2002 David Brin is a privacy heretic. He doesn't agree with those in the intelligence and law-enforcement communities who argue that Americans have to surrender freedoms to make their lives safe. Nor does he agree with advocates who argue that it makes sense to protect privacy at all costs -- certainly not if it means living with added insecurity. http://www.linuxsecurity.com/articles/privacy_article-5089.html * June Honeynet Scan of the Month June 4th, 2002 This month's challenge is to make sense of a seemingly innocuous flurry of UDP packets. All submissions are due no later then 22:00 GMT, Friday, 21 June. Results will be released Friday, 28 June. http://www.linuxsecurity.com/articles/intrusion_detection_article-5086.html ------------------------------------------------------------------------ Distributed by: Guardian Digital, Inc.
