OpenDNS says its free address-lookup service makes Web sites load faster, and that it blocks malicious, data-thieving phishing schemes and other threats.

You want to pay up your credit card account immediately, as you just remembered that today is the due date.

In a previous article, I discussed how using Border Gateway Protocol (BGP) to redirect routes can be an effective method for maintaining Web services in the event that the host Web site is rendered inaccessible.

Acme Packet(R), the leader in session border control solutions, today announced that its Net-Net(R) session border controllers (SBCs) have been certified for Stealth Communications' Voice Peering Fabric (VPF).

In a twist on distributed denial-of-service attacks, cybercriminals are using DNS servers--the phonebooks of the Internet--to amplify their assaults and disrupt online business.

A number of flaws in the software that is used to administer the Internet's Domain Name System have been discovered by researchers at Finland's University of Oulu.

A new threat to the internet is multiplying through DNS servers that are more open than they should be, delegates to last month's ICANN's Wellington conference and New Zealand Network Operators Group (NZNOG) meeting heard.

Hackers have struck DNS servers at Network Solutions with a denial-of-service attack, resulting in a brief performance degradation for customers.

Domain-name registrar Joker.com acknowledged this weekend that distributed denial-of-service attacks had caused numerous problems for customers that use its domain-name service (DNS) servers to advertise the Internet addresses of their domains.

Hackers used botnets and DNS servers to swamp networks with torrents of data.

The Massachusetts Institute of Technology has announced that it will be discontinuing support for Kerberos 4.

A little while ago, the notion of RSS highjacking grabbed the headlines and feed publishers everywhere where living in sheer agony, waiting for their reader count to drop, their faithful listeners to be piped smut through the magic of fraudulent CNAME records.

In a previous tip, I offered some tricks to help you and your users identify URL spoofing scams -- but user education can only go so far. Today I'll discuss steps you can take to help lock down Windows systems.

About one in 20 domain names - some 2.3 million Web sites - have been registered with patently false data in required contact information fields, Congressional auditors reported Wednesday.

The deployment of DNSsec, an enhancement to the domain name system that could protect against certain types of phishing and pharming attacks, is still facing skepticism and resistance from those who would be involved in implementing it.

Domain name service goes down. A broken piece of hardware in Network Solutions' domain name system rendered 120,000 websites unreachable this Monday morning.

Incorrect decoding of malformed DNS packets causes certain DNS implementations to hang or crash. DNS defines a mechanism for conserving bytes in a DNS query or reply packet by avoiding repetition of character strings ("labels") in a domain name.

A large number of Domain Name System (DNS) servers are wrongly configured or running out-of-date software, leaving them vulnerable to malicious attacks.

A security study of over 1.3 million DNS servers found that 84% of them where vulnerable to various types of attacks. Conducted by The Measurement Factory, the research indicated that pharming attacks would likely succeed on most of the servers.

Four in five authoritative domain name system (DNS) servers across the world are vulnerable to types of hacking attacks that might be used by hackers to misdirect surfers to potentially fraudulent domains.
