Why IPv6 Performance Monitoring Is A Global Necessity

Posted by Alex Ivanoff On February - 20 - 2009

ipv6 performance monitoring

The switch to IPv6 is on. In June 2008, the U.S. federal government, which is arguably the world’s largest single enterprise, required that all its executive agencies add IPv6 to their network backbones. The European Commission recently set an IPv6 target adoption rate of 25 percent by 2010, and the chairman of the Asia Pacific Network Information Centre predicted that all IPv4 addresses will be depleted by 2011, forcing wide-scale IPv6 adoption. A number of Internet powerhouses, such as Google and Alta Vista, have now deployed IPv6 accessible websites. Operating systems, such as the latest versions of Microsoft Windows, include IPv6 support.

Protecting DNS Server And Performing DNS Monitoring

Posted by Alex Ivanoff On February - 12 - 2009

In hierarchical structure of Internet DNS servers may be called nerve knots which directly influence the whole existence of the Internet. What can threaten their “health”? What can put them out of action? And can one protect DNS servers? Before we answer the questions, let’s see what task DNS servers carry out. In a few words, the main mission of DNS servers is translation of domain names into IP addresses and back. This means, servers must get requests, process them and send responses. DNS servers must keep data about supported network addresses; they exchange requests with servers of higher level in case they cannot give a response on their own. That’s enough to see what dangers potentially threaten DNS servers.

Security Threats in 2008. Current trends.

Posted by Alex Ivanoff On February - 11 - 2009

Kaspersky Laboratories published an annual report where most actual security threats are reviewed and analyzed. Experts say, the most current trend is the development of a complex global virus ‘eco-system’. Almost 90% of malware were produced for the purpose of subsequent selling. Chinese hackers and virus writers made the major part of the malware, however the most sophysticated examples of spyware and viruses were made in Russia.

Last year “Kaspersky Lab” reported that 24 million users had been attacked from Internet. The experts warn of increasing number of social network attacks and huge growth of the number of malware used to steal credentials for online games. Another urgent problem that grows in a scary fast pace is spread of rootkits. Rootkits are special tools used to hide malicious software on a user’s system by takeover of control over system functions or data structures. Botnets become more and more widespread and therefore represent one more critical threat in the modern IT world.

At the same time electronic junk mail distribution has not grown significantly. Avarage part of junk in email traffic has reached 82.1% — this is 2.1% more than in 2007. The world’s leader of spam discribution is Russian Federation (22%).

The experts predict that the situation will get much worse in 2009. What can be done to avoid distressing consequences? Do as much as possible to protect your PC, your mobile devices, your network environment and your private data. Update your antivirus daily, use a firewall, be careful when paying at internet shops and subscribe for a website monitoring account in order to know first if your blog has been defaced or infected by a malware.
