DNS Poisoning
Posted by Mourad Ben Lakhoua in News on February 23, 2009
security researcher Dan Kaminsky who works at security services firm IOActive, said this week at BlackHat that the time may have come for IT vendors and users to consider broad adoption of the more-permanent security protections offered by DNS Security Extensions, or DNSSEC, technology.
The cache-poisoning flaw was publicly disclosed last July and after several months was discovered by Kaminsky, who first notified IT vendors to give them time to develop a fix. When he finally detailed the vulnerability, Kaminsky said it existed at the DNS protocol level and was so ubiquitous that virtually every domain name server resolving IP addresses on the Internet was vulnerable to attack.
The flaw could be used by attackers to spoof DNS traffic, potentially enabling them to redirect Web traffic and e-mail messages to systems under their control. Other security researchers said that although the concept behind such attacks had been well understood for some time, Kaminsky demonstrated an extremely effective way in which the attacks could be carried out.

Computing in the Cloud Models- Right Now
Posted by Mourad Ben Lakhoua in Cloud Computing Security on February 1, 2009
In the last months there has been a rapid increase in investment in the Cloud Computing and related areas. This growth is due to the demand for virtual “cloud” resources, the Idea of Cloud Computing is near another approach called utility computing, where computing resources are treated as a service and takes into account the amount consumption like the usual public services (electricity or water).
Cloud Computing provides a numerous benefits from cutting coast, saving time ,held to high standards, must offer a proof of security certifications, and are subject to examinations by auditors, Making them under much higher analysis than typical in-house security teams.
So by looking to all these points it is clear that the Solution is in the Clouds.
