Enterprises located all over the world are still terrified to store their data on public clouds and this is mainly due to security concerns. But in a recent survey conducted by Forrester Research, it was revealed that these public IP Storage platforms are viable for backups and disaster recovery.
In February this year, around 209 database backup and DR professionals from North America, Asia and Europe were invited to take part in the survey. In this survey which was commissioned by Microsoft, Noel Yuhanna–a Forrester analyst said that organizations should strategically consider using public cloud services for scenarios involving backup and disaster recovery.
Noel estimated that around 15% of companies were currently performing database backups in cloud and this was a figure which has doubled in the last year. The main reason for the increased usage of Public clouds was said to be the growth in data and the need for an application which is available all the time and is economically viable too.
The survey revealed that more than 70% of enterprises have more than 2TB of data to deal with and in the next few years the data will grow to petabytes capacity. Noel admitted that 90% of data was created in the last two years and from that around 3.5 zeta bytes of data resides on the public cloud.
Noel said that he knew one organization which had 50k databases to manage and just 2k of them were considered critical.
According to the survey, the top challenges to use the cloud for backup and DR purposes were storage management-41%, securing backups-40% and automated backups and recovery 34%. Yuhanna explained that it can be complex to perform backups and encrypt them to the cloud. But if cloud backups and disaster recovery solutions are considered, it becomes really simple as encryption is already included into the backup process. The other benefit in using cloud storage is to conduct more frequent backups, redundancy and no limits on storage and seamless management.
The top three reasons stated in the survey for using public cloud for backups are 1.) Saving money on storage costs (61% of respondents admitted) 2.) Requirement for frequent backups (50 percent) 3.) Saving administrative costs (50 percent). The survey also confirmed that cloud was being used for multiple tier-2 backups.
When the topic of public cloud concerns erupted; Noel commented that security has been less of a concern today when compared with a few years ago. Also reliability of cloud services has increased and that is mainly due to the use of faster fiber connections, which offered the flexibility to backup large databases in a consistent way.
Supporting this theory, many among the survey respondents admitted that they were backing 20TB of data every day without any issues.
Debbie Lyons, a senior product manager with Microsoft’s SQL Server Group, added a few comments to the talk. She said that all new versions of SQL server are capable of holding direct backups and that too with the flexibility of availing the privilege of paying only for the storage utilized and that too with automatic data georeplication, along with data encryption.
For all those who believe that their systems are well protected by their much trusted Antivirus softwares, here’s an update. According a research carried out by a Singapore firm COSEINC, many anti-viruses are being riddled with security flaws. The research even confirmed that these softwares increase a computer’s attack surface and make the operating systems natural protection vulnerable.
As per the research carried out by Joxean Koret–a senior researcher at COSEINC, antivirus programs are instead exposing a large attack surface to malware propagators. In his research, Koret analyzed around 14-varieties of antiviruses and found that they were being exposed to vulnerabilities ranging from denial-of-services to flaws related to allow potential attackers to elevate their privileges on systems or to execute arbitrary code. Koret also discovered that some bugs were located in antivirus engines (which form the core of antivirus products) and in various other components.
Earlier, this month, Koret presented all his findings and discoveries at the SysScan 360 Security conference.
White presenting his findings, Koret quoted that “Exploiting AV Engines is not different to exploiting other client-side applications”. He added that they don’t use any special special-protections and rely on anti-exploitation technologies in the Operating system like Address Space Layout Randomization and Data Execution Prevention.
Koret added that antivirus engines typically run with highest system privileges and unknowingly start exploiting vulnerabilities. And this is where attackers with root or system access can gain control and start inducing bugs into the OSes.
According to the analysis of Koret, some antiviruses fail to sign their updates and do not use HTTPS connections to download them. This easily allows anyone attack or inject malicious files into the traffic and start executing them.
At the SysScan conference, Koret referred to the vulnerabilities like ASLR protection exposed by some antivirus products from Panda Security, Bitdefender, Kaspersky lab, ESET, Sophos, Comodo, AVG, Ikarus, Doctor web, MicroWorld Technologies, ClamAV, Fortinet, Avira, Avast, F-Prot, F-Secure and BKAV.
However, Koret did not report the issues exposed by the said companies on an individual note and said that the vendors must audit their own productline and run big bounty programs to attract independent research.

Many who are associated to the world of video surveillance might be interested in knowing the number of video surveillance cameras serving on a global note. Based on some historical camera shipments and the predicted lifespans of these devices, the count is estimated to be around 210,000,000. So, if each of these cameras operate as per industry’s standard resolution, quality and frame-rate settings and record 14 days worth of data, then they will be in need of 18.4 billion gigabytes of video storage approximately for a mere two- week recording.
Note- the estimated count and storage bytes can change in either way as there is no strong proof for the exact number of cameras deployed in the world and which are in working and non-working condition.
So, if the said amount of video storage is needed, then the number of hard disk drives needed to provide such storage capacity would stretch across United States once if laid end-to-end.
Therefore, these stats suggest on the staggering growth of surveillance and storage technologies over the past 15 years. Going with some historical estimates, the amount of storage demanded by today’s surveillance systems for just a period of two-weeks is 880 times more than the entire capacity manufactured in the year 1995. At the same time, the cost of storing such huge capacities has also come down drastically. In the year 1995, it was estimated that 1GB of storage costed roughly US$995; and today you can pick up a GB for a mere US$0.08 or probably even less.
“Make it bigger, make it faster and make it cheaper”, are the historic words of Al Shugart, who founded Seagate Technology.
Therefore, the conclusion is that increased capacities, improved performance and lower costs in storage technology are driving growth in global camera shipments.
Research firm In-Stat forecasts that over 41 million cameras were shipped in 2011 and in 2014 the count increased to 51 million when estimates till June 2014 were taken into account. Additionally, the demand for higher megapixel resolution cameras is on the rise and IP cameras are forecasted to experience a compound annual growth rate of 13.7% over the next three years. So, all this accounts to increase in storage needs and that too in an economical way.

Virtual Servers usage in enterprise environments is increasing worldwide and securing virtual environments is now at the top of mind for majority of IT departments. But when it comes to security option which is being addressed by IT departments, the facts are little bit disappointing.
A recent survey “Global IT Security Risks Survey 2014 Virtualization” was conducted on this issue by security solutions provider Kaspersky Lab and nearly 4500 IT professionals took part in this survey on a worldwide note. It was discovered in the survey that 64% of the said number of IT professionals agreed to the point that security needs to be utmost consideration when rolling out a virtual environment. From the said number, 46% of them believed that virtual environments can be adequately protected by conventional security solutions and 36% of them believed that security concerns in virtual infrastructure are significantly lower than in physical environments.
These findings clearly highlight a clear disconnect between how organizations perceive security for virtual environments and the tools available to handle the job.
In the same survey, it was also revealed that security concerns were acting as a significant barrier to implement virtualization and 41% of them stated that managing security solutions within virtual environments was a big struggle to forgo.
Security experts from Kaspersky suggest that virtual server is every bit as vulnerable as its physical counterparts and also reported that every year millions of malware are being circulated targeting these virtual environments. Experts also suggested that from the past couple of years, malware that is specifically designed to target virtual environments is under circulation and has affected more than 13% of virtual environments on a global note.
It was also revealed in the survey that virtualization is not only here to stay, but is in its full swing. Larger businesses are using virtual severs, either in cloud or hosted internally in data centers. More and more companies are showing interest in moving towards virtual applications and virtual desktop environments. So, at this juncture, IT professionals should understand the fundamental threat circling around the technology of virtual servers and employ appropriate security measures capable of defending virtual environments.
Many people are in an opinion that, since, they own a redundant storage solution such as a NAS or an IP SAN; they can ignore the presence of backup in their data storage environment. A number of them even think that the presence of any one of these specified solutions can save them from a disaster.
So, one may now get a thought that is this theory true and if it doesn’t what is the difference between a redundant storage and backup storage?
Typically, when discussing about redundancy in data storage, the focus easily shifts to RAID. And many people are in thinking that because they have RAID, they have backups of data. But this is a myth and to understand that it is false, let’s first find out the actual difference between a backup and a RAID and their purpose of deployment.
- RAID- RAID is nothing but redundant array of independent disks. It can be configured in several ways. But the most preferred levels are RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10.
- Backups are copy of original data, stored for the purpose of having a second copy of an original source and which can be recovered in a specific time frame, in order to witness data continuity.
RAID cannot protect against failures such as file corruption, files being overwritten, human error, catastrophic damage, malware and software bugs. In a similar fashion, backup refuses corrupted files, as it cannot read the blocks of corrupt file and so the data lying in those corrupt files will not be saved as a second copy.
Therefore, it is better if you first figure out these points from your enterprise data storage environment and then go for a solution search. Also try to get both these solutions on an individual or in a unified note.
