Cloud storage: Security is still a problem

The new claim is that the vulnerabilities caused by DNS bugs make cloud computing technology an adventure, for example, that users are using a CRM product in SaaS mode, and how users know that his browser is actually connected to the vendor's server when the salesman type the SaaS service provider's Web site. Instead of going to a cheating rogue?

By hijacking the Comcast company's Internet portal, this May, hackers gained an administrator account of the Comcast Network solution and directed users to the infected Web page, although it took several hours for the company to regain control of its website, but if the attacker's behavior was more subtle, Then they could cause serious financial damage by intercepting the Comcast company's customer data, not just a little embarrassment.

Security DNS has been supporting the Internet's name-resolution system for the past 20 years, but today it has been put on the front desk to become a high-profile focus, and not long ago, a researcher at security company IOActive Dan Kaminsky accidentally announced a serious vulnerability to DNS. The flaw makes hijacking a domain name a trivial matter in just a few minutes, and what is the real risk? At least this led to the creation in July of the largest number of major security software in the history of the same time the release of the Patch records, 16 vendors share the flaws found in Dan Kaminsky, This includes key manufacturers of DNS server-related technologies, such as Cisco and Microsoft Sun Microsystems, all of which released their companies ' patches on the same day.

If we cannot rely on DNS, we will extend it to not allow business-critical business units to access any mission-critical applications on the Internet, or we can choose to believe that sensitive data sent to the SaaS provider has not been intercepted. This sentiment actually resonates with everyone: In the recent survey of cloud computing, security is the most frequently mentioned topic of cloud computing.
