This HOWTO will also deal with non-linux applications: there is no use to issue certificates if you can't use them. http://www.linuxsecurity.com/articles/cryptography_article-4967.html * How secure is your password? May 10th, 2002 In order to access computer networks, online bank or e-mail accounts, we need a wide range of usernames and passwords. Constant attention is required to track what our name is in each virtual environment, and what password is needed at that moment to access personal information. http://www.linuxsecurity.com/articles/network_security_article-4963.html * Buffer Overflows - What Are They and What Can I Do About Them? May 6th, 2002 Buffer overflows have been a problem in software-based systems and applications for a long time. One of the first significant computer break-ins that took advantage of a buffer overflow was the Morris worm, and that happened in November 1988. The worm took advantage of a buffer overflow in the finger service, a service that dispenses information about the set of users logged into a UNIX-based computer system. http://www.linuxsecurity.com/articles/general_article-4932.html +------------------------+ | Network Security News: | +------------------------+ * Decoding IPsec: Understanding the Protocols of Virtual Private Networks May 10th, 2002 Acquiring a deeper understanding of how virtual private networks (VPNs) operate can be a daunting task. It traditionally has required sorting through scattered information and deciphering technical standards that contain a potentially confusing assortment of acronyms and algorithms. http://www.linuxsecurity.com/articles/cryptography_article-4964.html * Simplicity and Awareness - Keys to Network Security May 9th, 2002 Few people believe that maintaining a sound network security posture is easy. Those who do are deluding themselves, unless they practice two fundamental tenets of security: simplicity and awareness. http://www.linuxsecurity.com/articles/network_security_article-4956.html * Firestarter: 5 minutes to a Linux firewall: Part 2 May 8th, 2002 The following article is part two of a two part series. "Alternately, you could create limit rules to accept only a certain number of requests every second. Or if you have monitoring software that requires your box to be "pingable," you could accept ICMP requests from only a certain IP or set of IP addresses." http://www.linuxsecurity.com/articles/firewalls_article-4946.html +------------------------+ | Cryptography: | +------------------------+ * Security IC suppliers split over encryption methods May 12th, 2002 Growing security concerns within the enterprise communication market are challenging chipmakers to develop advanced, silicon-based encryption techniques that will not erode processor performance. http://www.linuxsecurity.com/articles/vendors_products_article-4969.html +------------------------+ | Vendor/Products: | +------------------------+ * OpenSSL 0.9.6d beta 1 released May 10th, 2002 A first hand approach on how to manage a certificate authority (CA), and issue or sign certificates to be used for secure web, secure e-mail, or signing code and other usages. http://www.linuxsecurity.com/articles/cryptography_article-4968.html * GnuPG 1.0.7 released May 8th, 2002 The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication and data storage. It is a complete and free replacement of PGP and can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440. http://www.linuxsecurity.com/articles/cryptography_article-4950.html +------------------------+ | General: | +------------------------+ * Sharing seen as critical for security May 9th, 2002 The private sector manages more than 85 percent of the nation's critical infrastructure and must therefore collaborate with the government to protect those resources, according to government and industry leaders speaking at a May 8 Senate Governmental Affairs Committee hearing. http://www.linuxsecurity.com/articles/government_article-4959.html * Social Engineering: The Human Side Of Hacking May 9th, 2002 A woman calls a company help desk and says she's forgotten password. In a panic, she adds that if she misses the deadline on a big advertising project her boss might even fire her. http://www.linuxsecurity.com/articles/hackscracks_article-4954.html * Security experts swarm to Honeynet challenge May 9th, 2002 Reverse engineering project to unravel binary caught in the wild The Honeynet Project, which has been monitoring black hat hacking activity over the past year, has set up a new challenge to help develop reverse engineering skills throughout the security community. http://www.linuxsecurity.com/articles/intrusion_detection_article-4957.html * Security myths costing firms May 8th, 2002 SECURITY guru Peter Tippett loves to shock people. He invites IT professionals to seminars on network security and then says you don't need more network security - at least, you don't need as much as vendors want to sell to you. Spend up on anti-virus software if you want to, he said. http://www.linuxsecurity.com/articles/general_article-4948.html ------------------------------------------------------------------------ Distributed by: Guardian Digital, Inc.
