Back in the all-wired age, no one worried about wardriving and password sniffing. Now, protecting against those threats is standard.
The risks and security implications of moving your sensitive data assets to the cloud are not yet fully understood. One thing thats clear, though, is that the cost advantages of moving to the cloud means that its a matter of when, not if.
Companies eschewing the cloud will quickly be at a disadvantage against their cloud-embracing rivals. ITs security toolbox will be much different in five years than it is today.
Cloud security may well have its WEP moment, but itll eventually evolve. How it will change, though, is much debated, and the signal-to-noise ratio when it comes to cloud security advice is not high.
Many look at cloud security through a corporate LAN lens. Others believe that any data outside the corporate firewall is basically lost. Still others believe, naively, that the cloud providers will take care of these problems for them. Some misconceptions are more problematic than others.
Here are five dangerous cloud security misconceptions that could compromise overall security.
As IT gets squeezed by corporate budget cuts and an ever greater need to stay on top of patches, upgrades and mushrooming vulnerabilities, the idea that you can handle security better than a large cloud provider with deep pockets and a dedicated security staff is misguided.
Remember, when a corporation loses sensitive data, its usually an inside job, said Brian Curry, VP of Products and Business Strategy at YouSendIt, a provider of secure digital content delivery services. Some insider will have access to systems they shouldnt, and data is at risk. Clearly, reducing or eliminating insider attacks is a huge security boon.
In many corporations, once you are credentialed, you can go pretty much anywhere you want. And how many enterprises have critical severs in unlocked rooms or even closets that pretty much anyone can enter? Ethernet ports are everywhere. Being inside the building essentially means that you are deep inside the network.
Compare that to a cloud vendor. They have multiple data centers backup and disaster recovery should be a given with the cloud and anyone entering must pass through layers of physical and often biometric security.
Moreover, reputable cloud vendors must comply with numerous regulations, are audited frequently and their business depends on delivering secure access to data. Major breaches equate with major customer defections.
Finally, in an enterprise setting, security is often the last thing IT worries about. Instead they spend the bulk of their time on mundane, cumbersome tasks like patches and password resets. In these days of doing more with less, there may not even be a dedicated security professional on staff.
If a cloud providers security is as lax as it is at many enterprises, they wont be in business very long.
People speak and think of the cloud generically. A cloud is a cloud is a cloud. Nothing could be further from the truth.
SLAs, security, reliability and uptime can all vary greatly from provider to provider, said Rami Habal, Director of Product Marketing for Proofpoint, a SaaS security and compliance provider.
Habal believes its important to have SLAs that go beyond basic uptime and reliability. SLAs should cover the applications themselves, and even what the vendor will do in the event of a breach or a DDoS attack.
Cloud vendors should be scrutinized just as closely as traditional hardware and software vendors. Conduct pilots, pick apart their security policies, negotiate favorable SLAs and seek out third-party validation of their service.
There are multitudes of attacks on the virtual machines that can be launched from another virtual machine running on the same cloud hardware. So, securing the data by security communication alone, such as by https or VPN, will still be insecure, said Pravin Kothari, founder and CEO of CipherCloud.
One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
