Recently we have examined both the conveniences and concerns regarding cloud services, and the conversation is most likely far from over. National Security Agency surveillance has definitely raised concerns about privacy of user data in cloud services. Documents leaked by Edward Snowden indicate that the NSA has been collecting huge amounts of user data by cracking encryption technologies, using backdoor methods, and in some cases providing legal notice. As enterprises are using well-known cloud services like Amazon or Google, the PRISM revelations might lead to a negative impact on U.S. cloud storage companies, as the surveillance activities of the spy agency have taken a toll on the reputation of technology companies. People are becoming increasingly concerned about the privacy and security of their data stored in the cloud.
The NSA is basically devising all possible ways to break the security controls on the web to track and collect huge amounts of user data. The news about the NSA cracking encryption of common online security products and placing secret doors at the access points can further undermine the confidence of foreign businesses. The NSA has been successful in cracking the majority of the encryption codes on the Web, by using supercomputers, technical trickery, court orders, and behind-the-scenes persuasion. Apart from deciphering the encryption of online products, the NSA has devised programs to deliberately insert vulnerabilities in commercial products, so that they may collect more information by exploiting those vulnerabilities. The NSA asks these companies to deliberately make changes to their products in undetectable ways like leaking encryption keys, making random number generator less random, adding a common exponent to a public-key exchange protocol, and so on.
According to research done by the information technology and innovation foundation (IITIF), NSA surveillance may end up costing U.S. cloud service companies $22 billion through 2016. The prediction by IITIF assumes that the U.S. might lose about 10% of its cloud computing market to European and Asian competitors. The United States is considered a leader in cloud computing usage and innovation, but PRISM revelations might cause a shift away from leading data storage providers like Google, Yahoo, and IBM. Salesforce.com recently lost one of their major clients due to government surveillance activities. This is just one example showing the negative impact of surveillance on cloud services. In the future, if the government does not take a stand on reforming the surveillance programs, cloud service companies in this country might have to bear huge loss.
Taking all of the security concerns into consideration, many companies have requested the government to allow them to publish a transparent report of mass data collection requests made my the NSA. In order to gain the trust of their customers, it is extremely important for cloud service providers to be transparent regarding the storage and sharing of sensitive user information. The government needs to take action towards reforming the surveillance program, and allow companies to reveal more details about what data has been requested of them by the government. It also needs to establish international transparency to gain the trust of foreign customers.
Similarly, cloud service providers also need to implement strong security controls to ensure better safety of their customers from surveillance programs. It would be wide for them to construct strong encryption standards such as 256 bit-AES for better security. Encryption has time and again proved to be the most secure method for protecting data in the cloud. The keys used for encrypting sensitive customer data should be managed effectively by periodic key rotation and re-encryption of data with new keys. Employees should be not be given more access than what is needed to complete their tasks. Cloud storage companies should require strong passwords, longer keys, or complex hash algorithms to make it difficult for anyone to access user data.
I believe by implementing security measures and being transparent data usage, companies can gain the trust of their customers, and those who have been enjoying the benefits of U.S. cloud services might think twice before moving to alternate services. Under the light of NSA surveillance, cloud startups whose prime goal is to secure their customer data will see a huge growth in their business in the near future.

Cloud services are becoming increasingly popular these days, both among the public and business enterprises. While convenient, Cloud services can be extremely vulnerable to Denial of Service attacks (DoS). As more organizations are relying on cloud computing technology for their business operations, denial of service attacks, one of the most common forms of attack on the cloud, can prove extremely damaging. A DoS attack makes your network or machine unavailable to the intended users by flooding them with connection requests. Within the eighth annual Worldwide Infrastructure Security Report from security provider Arbor Networks, it was revealed how cloud services increase the risk of attacks. The report indicated: “94% of data center operators reported security attacks, 76% had suffered distributed denial of service (DDoS) attacks towards their customers, while just under half (43%) had partial or total infrastructure outages due to DDoS and yet only 14% of respondents had seen attacks targeting any form of cloud service.”

With healthcare data doubling every year, it can be extremely difficult for medical institutions to manage such a huge amount of information using traditional IT systems. This is one of the reasons why the healthcare industry is gradually moving towards the use of cloud services. A cloud storage system allows organizations to place data on a centralized electronic system that can be accessed anytime from anywhere. Cloud services can help the healthcare industry to access and manage health records effectively in order to provide better patient care. A properly implemented cloud storage system allows hospitals to process tasks effectively and quickly, without causing a drop in performance. Cloud computing has proven extremely beneficial and cost effective for patients and healthcare providers.

Cloud computing has become the driving force of today’s IT industry. More and more enterprises are moving towards this technology because of its flexibility, cost effectiveness, and easy deployment. According to the technology researchers at Gartner, the cloud services are expected to grow to $210 million by 2016. However, cloud computing is vulnerable to several security breaches and cyber attacks. The fact that the cloud hosts a tremendous amount of data makes them an attractive target for the cyber criminals. It is also extremely difficult to track or investigate cyber attacks on cloud services because of an ever changing set of users and data centers.

Security researchers have devised a unique method to trick the hackers trying to crack encrypted information. As you may know, encryption is one of the most effective methods of protecting data. However, it is seen that in many cases intruders are successful in getting into the system by trying different encryption-cracking methods. There are several sophisticated pieces of software that are capable of deciphering secure data. Keeping these security concerns in the forefront, two security researchers, Ari Juels and Thomas Ristenpart, from the University of Wisconsin Madison, have come up with a new encryption system called “Honey Encryption”.

The Point-of-Sale (PoS) malware attacks seem to be on the rise since last year. Many retailers like Target and Neiman Marcus became victims of such attacks. Recently, the RSA brought into light another PoS malware called “ChewBacca”. In the past three months, this Trojan has stolen credit and debit card information from dozens of retailers. While the majority of the retailers are based in the U.S., the attack has also been noticed in few other countries like Russia, Canada, and Australia. Due to lack of security controls on the PoS machines, they have become the easy target of financially motivated attacker, who is able to access millions of customer’s data. Let’s take a look at how the ChewBacca malware works. Continue reading…

If you are fond of playing the game Angry Birds like thousands of other people, then you need to be very careful regarding the privacy of your data. The NSA has been exploiting the vulnerabilities in “leaky” smartphone apps, like Angry Birds, to collect sensitive user information. The majority of apps transmit or share a certain amount of user data with the advertisers for targeted advertising. The mobile apps collect user information, and transmit that information through the Internet to the third parties. The data traveling through the communication channels contain information ranging from phone model, location, age, and gender of the users. Just imagine the amount of personal data which can be accessed by breaking into the communication links that carry sensitive information. Continue reading…

The Internet of Things has become an emerging trend in today’s age. As the number of devices connected via Internet grows, the risk of cyber attacks also increases. By connecting so many unsecured smart devices like TVs, refrigerators, etc. to the Internet, we are opening the doors to many malicious activities. Recently, a security research firm, Proofpoint, revealed an Internet of Things cyber attack that compromised more than 100,000 Smart TVs, refrigerators, and other smart appliances; 750,000 malicious email communications were sent out from these devices. Proofpoint noticed this attack during the holiday season, from December 23,2013, to January 6, 2014. The researchers observed thousands of malicious email messages coming a particular range of IP addresses. When they conducted further investigation, they realized that these messages are not coming from PCs, which are the most common medium for launching these attacks, but from unidentified devices running on the standard Linux platform. On pinging those devices, they found out that they were smart appliances connected within households.
According to Proofpoint, just as personal computers are compromised by botnets to launch attacks, cyber criminals are exploiting the vulnerabilities in smart home appliances by transforming them into “thingbots” to carry out malicious activities. One of the major intentions behind such kinds of attacks is to collect personal information about the victim. The more information the attackers have in their hands, the more powerful they become. Another reason why Internet connected devices have become more appealing to the attackers is because they have poor security controls and can be infected easily. The researchers of Proofpoint noticed during their investigation that the majority of the smart appliances were not configured properly or used default passwords. Unfortunately, when we talk about Internet security, most people visualize securing their laptops or tablets. We forget that other than our laptops, PCs, or Tablets, there are many more household appliances that are connected to the Internet, and it is equally important to implement security controls to protect them from attacks.
Lack of security awareness among the users of smart appliances it the most important reason why connected devices are more attractive to cyber criminals than PCs or laptops. People need to educate themselves about the vulnerabilities in the Smart appliances and implement recommended security controls to ensure protection. They should make sure that they change the default passwords of these devices before putting them to use. Users should always choose strong and complex passwords for better security, and change them on a regular basis. Often times, the industries developing these devices find it difficult to find and fix vulnerabilities compared to PCs and software appliances. They do not have the expertise or ability to patch the weaknesses in these devices. According to security expert Bruce Schneier, most common home routers run on old version of Linux operating system. The vulnerabilities may have been patched earlier, but it is extremely important to apply patches to them more frequently, because as the systems age their security vulnerabilities increases.
In order to apply patches the users need to manually download and apply them. It is rarely done because the users are never alerted about security updates, nor do they have the expertise to monitor the systems regularly and update patches. So, the best way to ensure protection from malicious attacks is to change your default password, and replacing them with strong, difficult-to-crack passwords. Keep your appliances connected to the Internet only as long as required; if you do not need your devices, disconnect them from the Internet. The 24/7 availability of connected devices makes them more vulnerable to attacks. Lastly, take the security precautions of connected devices just as seriously as your PCs or laptops.

As has been the trend of businesses, the makers of malware are also moving towards cloud services because of its flexibility, cost effectiveness, and easy maintenance. Malware distributors are embracing cloud services as a method of hosting malicious codes and adware. They are doing so either by buying services directly from the cloud service providers, or by compromising them. By hiding behind the names of legitimate cloud service providers like Amazon and GoDaddy, they can effectively serve malware to millions of Internet users. Hackers can use the trusted IP addresses of these major cloud service providers to initiate malicious activities without getting blacklisted. The cloud enables them to quickly and cheaply develop malware-infected sites, and bring them online. Some of these benefits of cloud computing have made cloud one of the attractive places for these malicious actors.
