  What is the point of encryption if you don’t know who for?
  30th, May, 2005

Dr. Walter, Head of Cryptography for Comodo Inc. and chair of the Trusted Computing Group (TCG) Peripheral Working Group, has clarified the relationship between encryption and authentication. The blurred definition to date has split the Certificate Authority industry into two groups. Authorities such as Comodo and VeriSign compete head to head, to deliver high assurance digital certificates whilst other groups concentrate on the low assurance market.
  Sentry CD - A different firewall approach
  30th, May, 2005

If you want to set up a Linux-based firewall, there's no need to run a bloated distribution that installs everything but the kitchen sink. If you are not afraid to get your hands dirty, and like having total control over your system, then Sentry Firewall CD (SFCD) is just what you need. It is a highly configurable, bootable CD that takes a minimalist approach to firewalling.
  Many unaware of browser-security link
  1st, June, 2005

Many American online computer users are unaware that choice of browser affects Internet security, and few switch browsers even when they know the risk, a Norwegian study said Monday.
  Network Security to Take Top Spot
  1st, June, 2005

Criminals aren't the only ones benefiting from the onslaught of threats that bombard corporate networks. Security vendors are also reaping the benefits.

According to Infonetics Research, worldwide security appliance and software revenue is forecast to hit $6.5 billion by 2008.
  Zombie machines used in 'brutal' SSH attacks
  2nd, June, 2005

It's a tedious activity that can put the best of IT administrators to sleep. But as security and compliance manager for a large U.S. healthcare organization, Adam Nunn has learned to study his network activity logs religiously. He knows that when the bad guys work overtime to break his defenses, those logs can be the first sign of trouble.

He had a more relaxed approach to log checking at home. But one day he had a look and was alarmed to find that more than 1,000 brute force attacks had been targeting his personal Web server for a month.
  An Introduction to Securing Linux with Apache, ProFTPd and Samba
  2nd, June, 2005

While the vast majority of Linux users are hard-core techies, some may be using Linux because they want to try something new, are interested in the technology, or simply cannot afford or do not want to use Microsoft Windows.
  Review: FreeBSD 5.4
  1st, June, 2005

One of the oldest Unix-like operating systems, FreeBSD, continues its advancement with the sixth release in the FreeBSD-5 series. Its developers have added nothing major, but have made many modifications, fixing a number of problems introduced in previous releases. FreeBSD 5.4 is the best release since 5.1, but it still may not be ready for prime time.

Everybody know that you're the OpenBSD and OpenSSH GURU and creator, one of most famous and used secure operating system nowaday. Why you created them? What did you need many years ago from os world when you created OpenBSD? What inspired you to write from scratch OpenBSD and OpenSSH? Read Full Text
  Employee Training & Education Can Mitigate Threats
  31st, May, 2005

“Many Internet threats are easily avoidable and just executed by employees who are simply unaware of their presence. Once briefed on basic Internet security, it is equally important to keep your employees educated as well. When new threats arise, send out memos alerting each employee of the threat, how to identify it, and what to do if and when they have it,? says security expert and Guardian Digital CEO Dave Wreski.
  Security Action Plans
  1st, June, 2005

Centralization, automation, problem prioritization--many IT-security professionals are embracing those concepts as they fight off the never-ending onslaught of threats. Security products can help businesses stem the flood of vulnerabilities, but IT teams also have to put in place processes to ensure that they're responding appropriately and being proactive in warding off potential dangers. Fact is, some companies spend too much on some parts of their organization and not enough on more-vulnerable areas.
  Fedora Directory Server Now Available To The Open Source Community
  1st, June, 2005

The Fedora Project, a Red Hat-sponsored and community-supported, open source collaboration project, today announced at the Red Hat Summit the availability of Fedora Directory Server. By making Fedora Directory Server freely available to the open source development community, Red Hat is enabling and encouraging the development of secure, enterprise technologies and providing customers and partners with increased choice. The availability of Fedora Directory Server licensed under the GPL underscores Red Hat's true commitment to open source innovation.
  How to crack passwords, and why you should
  2nd, June, 2005

Auditing passwords is a worthwhile venture, particularly in an environment that deals with sensitive information. Because systems encrypt passwords when they store them, you really can't properly judge the strength of a password unless you try to crack it. We suggest using a password-cracking tool such as John the Ripper. This tool works extremely well because it can crack MD5 passwords, which most systems currently use. In addition, it's much faster and more sophisticated than earlier password-cracking software such as Crack.
  Hackers target voice over IP
  2nd, June, 2005

Service providers need to focus more resources on voice over IP (VoIP) security if they are to provide the level of reliability and trust that subscribers have come to expect with traditional telephone services, analysts have warned.

According to a white paper from business consulting and systems integration firm BearingPoint, broadband operators need to address security problems before rushing to VoIP as a way to increase revenue and provide new services.
  Yahoo!, Cisco Combine Antispam Efforts
  2nd, June, 2005

  Lack of Confidence in IT Security Industry
  3rd, June, 2005

IT Security industry needs to convince citizens of its trustworthiness and the robustness of their products if it works to win a slice of the project associated with the introduction of ID cards. A recent research, published by Glasshouse Partnership, reveals that there is a lack of confidence in the ability to manage data security.
  US biometric ID request raises ID concern in UK
  30th, May, 2005

The UK government plans to issue its ID card as a passport with biometric identifiers stored in a chip – and the US wants those chips to be compatible with its own scanners, raising the possibility that US agencies could have access to the ID Card database.
  Cybersecurity czar will have hard road ahead
  2nd, June, 2005

  On the track of script-kid terrorists
  31st, May, 2005

CYBER terrorism is almost a dirty word among elite computer security professionals, and there's a high risk of being ridiculed if you use it in their midst. AusCERT director Nick Tate says you're more likely to generate public terror by flying an aircraft into a bank than by breaking through its electronic security cordon.
  Israeli Police Charge 18 With Industrial Espionage
  31st, May, 2005

Eighteen people have been arrested in one of Israel's largest industrial espionage schemes, police said Sunday, charging that business executives and private investigators used sophisticated software to infiltrate competitors' computers. The investigation implicated a car importer, two cell phone providers, and the nation's main satellite television company. Police said they were still sifting through documents and computer files to figure out the extent of the damage, but maintained that victims lost competitive bids and thousands of customers because of the spying.
  Hackers, Spammers Partner Up To Wreak Havoc
  3rd, June, 2005

A one-two-three assault of disparate spammer and hacker groups in the last 24 hours bodes nothing but ill for users, a security expert said Thursday.

The attack, which involves a new combination of malicious code, shows evidence of "tactical coordination that is unprecedented," said Sam Curry, vice president of Computer Associates' eTrust security group.
  New hack cracks 'secure' Bluetooth devices
  3rd, June, 2005

Cryptographers have discovered a way to hack Bluetooth-enabled devices even when security features are switched on. The discovery may make it even easier for hackers to eavesdrop on conversations and charge their own calls to someone else’s cellphone.
