Encrypted data at some point has to be decrypted for use, and that's where the security of the system can break down. That's not the only risk, however. "If a service provider holds the keys and someone comes knocking on the door with a lawful request ... the enterprise would not know that its information has been handed over," said PrivateCore's Vice President for Marketing Todd Thiemann.
Encryption combined with cloud storage has been hailed as a highly secure way for organizations to protect their data from Net marauders, but their value may be overstated, contend two security pros.While encrypting data is better than not encrypting it, where it's decrypted can be an important security consideration, said Steve Weis, CTO and cofounder of PrivateCore.
Data at rest that's been encrypted has strong protection. It's when the data has to be decrypted for use with applications that it can become vulnerable.
"If a company processes that data in the cloud or with an off-premises service provider, then the keys to that encrypted data can be exposed," Weiss told TechNewsWorld. "If those keys are compromised, their stored data can be compromised."
That's not a problem for organizations encrypting their data locally because the keys remain in their possession. However, "what we're seeing more and more are enterprises doing decrypting closer to where the data is," Weiss observed. "That means storing it and processing it in the cloud."
"To do that, they need to give the decryption keys to a server that's in the cloud," he continued. "The keys aren't being stored anywhere. They're being used in memory, but the memory is vulnerable to someone who has access to the machine."
Government IntrusionsHackers and malicious insiders aren't the only ones who may be able to compromise a company's encrypted data. If an organization doesn't have control of the encryption keys for its data -- a common scenario when using large service providers like Amazon, Microsoft and Google -- law enforcement or spy agencies may be able to legally access it.
"If a service provider holds the keys and someone comes knocking on the door with a lawful request, the service provider is going to have to respond to that, and the enterprise would not know that its information has been handed over," PrivateCore's Vice President for Marketing Todd Thiemann told TechNewsWorld.
A savvy government agency could break into an organization's encrypted data, even when the organization has control of its encryption keys.
If the encrypted data is stored with a service provider and the company wants to work with data online, it would have to unlock the data in the memory of one of the provider's servers. A snapshot can be taken of the data in that unlocked state.
"A lawful request could be made to snapshot the data," Thiemann explained, "and from that snapshot, you can get at the underlying encrypted data."
Threat TrendsWith half the year gone, cyberthreat trends are beginning to shape up for security pros. McAfee, for example, is seeing many hackers return to old ways.
"Many of the significant trends of the previous year went into remission, and older types of attacks, or retro-malware, grew significantly," McAfee Messaging Data Architect Adam Wosotowsky told TechNewsWorld.
Global spam, including the resurrection of pump-and-dump stock schemes, increased for the first time in three years, he added.
Another trend identified is the growth of storage stack attacks, also known as "master boot record" attacks.
"These attacks infect a machine's storage system and take control of the entire device," Wosotowsky said. "These MBR attacks have increased more than 30 percent so far this year."
Democratization of MalwareSocial networks continued to become a fertile area for Net bandits.
"Hackers will take over a social networking account and use the contacts for that account to distribute malware as a trusted person," George Tubin, a senior security strategist with Trusteer, told TechNewsWorld.
"You're more likely to click on a link if a friend embeds a link in a tweet," he added.
Cybercriminals have been expanding their target pool beyond banks and into the enterprise and e-commerce, noted Tubin.
"That has to do with banks -- especially larger banks -- getting better at blocking some of these attacks," he said.
Also during this year, the democratization of the malware industry has become increasingly apparent, added JD Sherry, vice president of technology and solutions at Trend Micro.
"The shadow economy has created quite the black market for malware," he told TechNewsWorld. "It's allowed cybercriminals and miscreants to be able to acquire those assets easily, hence democratizing their production and distribution."
- June 29. Spam attack on Instagram uses compromised accounts to post fruit photos with links to a dieting Web page on a BBC website. Links were clicked on by more than 30,000 users before the image sharing service addressed the problem.
- June 30. Ubisoft, a game maker whose stable includes Assassin's Creed, alerts users of a data breach and recommends they change their passwords.
