Tips for Data Recovery of RAID 5 Drives

RAID technology is the use of multiple disks to emulate the performance of one disk. This is usually done to increase the safety and redundancy of data, the speed of read/write performance, or a mixture of both. It has great use in the management of corporate data.

Data is integral to today’s businesses. Information is said to be power and right fully so, especially when you consider the nature of the economy of the modern world in this age we call the Information Age.

This has led to the explosion of the integration of Information Technology into most businesses. Most businesses employ some sort of Information System which stores sensitive information vital to a broad spectrum of operations.

These systems may be reliable, especially as technology increases the amount and accuracy of information stored in various media and systems. However, the probability that these systems will crash or that data will be lost cannot be ignored.

Most data crashes occur when some physical or logical error is introduced into a system. Hard disks, CD-ROMs, Tape Drives and other storage media can and will fail eventually. This could be caused by a host reasons – power outages, physical damage to media, head crashes, motor problems and the like.

Whatever the reason, you will need a means to restore all this data. This is especially true if for some reason the deleted, destroyed or corrupted data contains information that is not backed up or existing in any other location anyway.

A special consideration when planning for backup strategies is the type of storage you choose to employ. If you are using a RAID set up for your data access and recording, you will have to keep in mind a few extra tips on top of your general knowledge data management.

1. Regular Maintenance – While RAID components are usually reliable, it is recommended that regular back ups are performed at set intervals. There is always the chance that such systems will have logical and continuity problems. For this, you may want to employ special software to maintain the integrity of your RAID configuration.

2. Know Your Problem – It may take a little training to know the difference, but many of the RAID problems can be solved by using readily available RAID data recovery tools. If in the event that such software does not work, then you may consider the services of a professional data recovery expert.

These experts are highly-trained and employ equipment not readily available to most people to recover badly damaged disks, and hopeless media.

3. If Possible, Use Software RAID instead of Hardware RAID – while software RAID is a viable alternative to hardware RAID. Software RAID has a few practical setbacks.

Software RAID is not as fault tolerant as hardware RAID. It may not be an error magnet, but it still is a lot less reliable in comparison to hardware RAID

Also software raid takes up valuable system resources and needs to boot up before it can be used. This is not saying that software RAID should be avoided like the flu; it is jus that there are really good reasons to use hardware RAID instead

4. Invest in Maintenance – While using precious hours backing up and maintaining your RAID can prove to be taxing, and by all means unnecessary, you only have to look at a professional data recovery bill to realize that it was all worth it.

Telematics and Big Data: Next Generation Automotive Technology

Telematics, Big Data, and Analytics are the three big important ways that are driving the auto industry forward. In this article, we will see how big data analytics, with the insights of information processing, can help transform the automotive and transportation industry globally.

The future of telematics is with big data.

Traditionally, in most automotive and transportation enterprises, specialized business processes have always been analyzed and modeled on whatever limited empirical data or contextual information was available to them. Proper data was few and far between. Or, even if the required data was available, enterprises hardly had any technological know-how with them to harness all the information necessary for their use. It was quite a difficult task to deal with such a situation where enterprises heavily relied upon conventional methods such as going through previous driving records, including taking into account people’s age and gender, locale demographics to accurately predict risk levels among its consumer base. This was something haphazard, awkward and unreliable.

Now with the advanced big data analytics, accessibility to scores of information and the science of telematics are putting the current understandings in new light, offering new conversation starters, and creating new potential outcomes that were not really possible before. “Big Data” as we know it is changing everything for the better. It is changing how the vehicles are built, how they work, how we use them and how they collaborate with everything else in this world: From vehicle-assembling to insurance underwriting, to traffic modeling to optimizing traffic routes, Big Data is changing the world of car/fleet transportation industry in a big way.

Big data analytics plays a very important role in the telematics field. The fact of the matter is that the science of telematics which involves telecommunications and vehicular technologies demonstrates how big data analytics can improve supply chain management, fleet management, increase yield and drastically reduce material costs, not to mention the quality and safety issues that never get compromised using proper big data analytics. In fact, the use of relevant data directly leads to more opportunities. It is in this context we will see how Big Data is bringing transformative elements into the various industry sectors especially in insurance, financial, automotive and transportation and other sectors and improve their business processes.

Telematics All The Way

Telematics is ushering an era of big changes. The way vehicles are insured and how they are driven or repaired are all changing for the better.

Earlier, we have seen that insurance and maintenance standards of vehicles were based on some kind of conjecture and the rough utilization of crude data that was available at hand. But with the use of telematics, a strong evidence of data is promptly accessible that can revamp entire branches of the commercial enterprises and change drivers’ driving behaviors.

Thanks to telematics, the wealth of data that can be derived from vehicles can also be made available to drivers. This is also one of the big changes that telematics promises. As far as valid data is concerned, there are simple ways people can immediately access from their connected car, and this same data can also be transmitted to the manufacturers or insurance companies for that matter. So when data is available and is accessible to users then there is going to be better understandings of their vehicles’ performance, ultimately resulting in helping drivers adopt good driving behavior. Drivers will have access to GPS-related data that will let them know their driving styles, including real-time information on fuel consumption, speed limits, hard acceleration, braking, phone distraction, etc. All this useful information can impact not only their driving performance but also can extend the longevity of their cars.

Driving Innovation and Continued Growth for Auto Insurance

To give you just one example: Consider the insurance industry. Using the great combination of telematics and big data analytics, insurance companies are able to enhance their business processes to an extent that was not possible before.

Basically, the insurance industry is based on analytics and probability. Therefore, to have a proper access to accurate and in-depth data that identifies with every customer’s lifestyle and risk always works in the best interest of the insurance industry. This is an area where telematics has been adding quite a lot of significant value propositions that matter greatly to both insurance companies and their paying clients alike.

With telematics and big data analytics, insurance companies don’t have to resort to guesswork to fix premiums for their customers. It has enabled insurers to reward policyholders, who display good driving conduct and check their vehicle health stats, with lower premiums and rebate offerings by taking the guesswork out of the equation. This is nothing but a big data approach to telematics insurance.

Telematics is a positive trendsetter and has grown exponentially in recent years. The positive impact that it has over companies and consumers alike is proving to be a win-win deal for everyone. And as far as telematics is concerned Big Data would be there too, working hand in hand. Not only consumers but automotive manufacturers and service providers as well are going to get greatly benefitted from the marriage of big data and telematics. And since the relationship is really symbiotic, big data is going to be the future of telematics. Embrace big data and telematics in a big way!

The Necessity of Information Governance and Data Classification for Complying With the GDPR

Approaching the new General Data Protection Regulation (GDPR), effective from May 2018, companies based in Europe or having personal data of people residing in Europe, are struggling to find their most valuable assets in the organization – their sensitive data.

The new regulation requires organizations to prevent any data breach of personally identifiable information (PII) and to delete any data if some individual requests to do so. After removing all PII data, the companies will need to prove that it has been entirely removed to that person and to the authorities.

Most companies today understand their obligation to demonstrate accountability and compliance, and therefore started preparing for the new regulation.

There is so much information out there about ways to protect your sensitive data, so much that one can be overwhelmed and start pointing into different directions, hoping to accurately strike the target. If you plan your data governance ahead, you can still reach the deadline and avoid penalties.

Some organizations, mostly banks, insurance companies and manufacturers possess an enormous amount of data, as they are producing data at an accelerated pace, by changing, saving and sharing files, thus creating terabytes and even petabytes of data. The difficulty for these type of firms is finding their sensitive data in millions of files, in structured and unstructured data, which is unfortunately in most cases, an impossible mission to do.

The following personal identification data, is classified as PII under the definition used by the National Institute of Standards and Technology (NIST):

o Full name

o Home address

o Email address

o National identification number

o Passport number

o IP address (when linked, but not PII by itself in US)

o Vehicle registration plate number

o Driver’s license number

o Face, fingerprints, or handwriting

o Credit card numbers

o Digital identity

o Date of birth

o Birthplace

o Genetic information

o Telephone number

o Login name, screen name, nickname, or handle

Most organizations who possess PII of European citizens, require detecting and protecting against any PII data breaches, and deleting PII (often referred to as the right to be forgotten) from the company’s data. The Official Journal of the European Union: Regulation (EU) 2016/679 Of the European parliament and of the council of 27 April 2016 has stated:

“The supervisory authorities should monitor the application of the provisions pursuant to this regulation and contribute to its consistent application throughout the Union, in order to protect natural persons in relation to the processing of their personal data and to facilitate the free flow of personal data within the internal market. “

In order to enable the companies who possess PII of European citizens to facilitate a free flow of PII within the European market, they need to be able to identify their data and categorize it according to the sensitivity level of their organizational policy.

They define the flow of data and the markets challenges as follows:

“Rapid technological developments and globalization have brought new challenges for the protection of personal data. The scale of the collection and sharing of personal data has increased significantly. Technology allows both private companies and public authorities to make use of personal data on an unprecedented scale in order to pursue their activities. Natural persons increasingly make personal information available publicly and globally. Technology has transformed both the economy and social life, and should further facilitate the free flow of personal data within the Union and the transfer to third countries and international organizations, while ensuring a high level of the protection of personal data.”

Phase 1 – Data Detection

So, the first step that needs to be taken is creating a data lineage which will enable to understand where their PII data is thrown across the organization, and will help the decision makers to detect specific types of data. The EU recommends obtaining an automated technology that can handle large amounts of data, by automatically scanning it. No matter how large your team is, this is not a project that can be handled manually when facing millions of different types of files hidden I various areas: in the cloud, storages and on premises desktops.

The main concern for these types of organizations is that if they are not able to prevent data breaches, they will not be compliant with the new EU GDPR regulation and may face heavy penalties.

They need to appoint specific employees that will be responsible for the entire process such as a Data Protection Officer (DPO) who mainly handles the technological solutions, a Chief Information Governance Officer (CIGO), usually it’s a lawyer who is responsible for the compliance, and/or a Compliance Risk Officer (CRO). This person needs to be able to control the entire process from end to end, and to be able to provide the management and the authorities with complete transparency.

“The controller should give particular consideration to the nature of the personal data, the purpose and duration of the proposed processing operation or operations, as well as the situation in the country of origin, the third country and the country of final destination, and should provide suitable safeguards to protect fundamental rights and freedoms of natural persons with regard to the processing of their personal data.”

The PII data can be found in all types of files, not only in PDF’s and text documents, but it can also be found in image documents- for example a scanned check, a CAD/CAM file which can contain the IP of a product, a confidential sketch, code or binary file etc.’. The common technologies today can extract data out of files which makes the data hidden in text, easy to be found, but the rest of the files which in some organizations such as manufacturing may possess most of the sensitive data in image files. These types of files can’t be accurately detected, and without the right technology that is able to detect PII data in other file formats than text, one can easily miss this important information and cause the organization an substantial damage.

Phase 2 – Data Categorization

This stage consists of data mining actions behind the scenes, created by an automated system. The DPO/controller or the information security decision maker needs to decide if to track a certain data, block the data, or send alerts of a data breach. In order to perform these actions, he needs to view his data in separate categories.

Categorizing structured and unstructured data, requires full identification of the data while maintaining scalability – effectively scanning all database without “boiling the ocean”.

The DPO is also required to maintain data visibility across multiple sources, and to quickly present all files related to a certain person according to specific entities such as: name, D.O.B., credit card number, social security number, telephone, email address etc.

In case of a data breach, the DPO shall directly report to the highest management level of the controller or the processor, or to the Information security officer which will be responsible to report this breach to the relevant authorities.

The EU GDPR article 33, requires reporting this breach to the authorities within 72 hours.

Once the DPO identifies the data, he’s next step should be labeling/tagging the files according to the sensitivity level defined by the organization.

As part of meeting regulatory compliance, the organizations files need to be accurately tagged so that these files can be tracked on premises and even when shared outside the organization.

Phase 3 – Knowledge

Once the data is tagged, you can map personal information across networks and systems, both structured and unstructured and it can easily be tracked, allowing organizations to protect their sensitive data and enable their end users to safely use and share files, thus enhancing data loss prevention.

Another aspect that needs to be considered, is protecting sensitive information from insider threats – employees that try to steal sensitive data such as credit cards, contact lists etc. or manipulate the data to gain some benefit. These types of actions are hard to detect on time without an automated tracking.

These time-consuming tasks apply to most organizations, arousing them to search for efficient ways to gain insights from their enterprise data so that they can base their decisions upon.

The ability to analyze intrinsic data patterns, helps organization get a better vision of their enterprise data and to point out to specific threats.

Integrating an encryption technology enables the controller to effectively track and monitor data, and by implementing internal physical segregation system, he can create a data geo-fencing through personal data segregation definitions, cross geo’s / domains, and reports on sharing violation once that rule breaks. Using this combination of technologies, the controller can enable the employees to securely send messages across the organization, between the right departments and out of the organization without being over blocked.

Phase 4 – Artificial Intelligence (AI)

After scanning the data, tagging and tracking it, a higher value for the organization is the ability to automatically screen outlier behavior of sensitive data and trigger protection measures in order to prevent these events to evolve into a data breach incident. This advanced technology is known as “Artificial Intelligence” (AI). Here the AI function is usually comprised of strong pattern recognition component and learning mechanism in order to enable the machine to take these decisions or at least recommend the data protection officer on preferred course of action. This intelligence is measured by its ability to get wiser from every scan and user input or changes in data cartography. Eventually, the AI function build the organizations’ digital footprint that becomes the essential layer between the raw data and the business flows around data protection, compliance and data management.
