Despite the possibility to encrypt big data and the essentiality of doing so, this security measure is often ignored. Head of Data Analytics Department, ScienceSoft. If you choose to deploy Web services, security will be a major issue. Data provenance difficultie… Think holistically to secure a system, considering the flow of data through the entire system rather than testing individual points. Each component may look secure, but risk may still occur at the interface points or the points of inconsistency across systems. Cloud computing and services are relatively new, yet data breaches in all forms have existed for years. Despite claims that protecting data assets is strategic to an enterprise, the scope of data protection projects is all too often either regulation or department-specific. Begin by doing a thorough inventory of sensitive data (See fig 1).Then develop a “Sensitive Data Utilisation Map" documenting your findings. Protegrity is exhibiting at Infosecurity Europe 2008, Europe’s number one dedicated Information security event. Knowing what enterprise data protection technologies, policies and procedures are “reasonable” relative to peer organisations is useful information, but don't allow others' actions to determine your security plan and goals. This way, your data processing can be effectively ruined: cybercriminals can make mappers produce inadequate lists of key/value pairs. For example, unauthorized or rogue users might steal data in compromised accounts or gain unauthorized access to data coded … Working with big data has enough challenges and concerns as it is, and an audit would only add to the list. Computer System Security Requirements Computer System Security Requirements shall mean a written set of technical standards and related procedures and protocols designed to protect against risks to the security and integrity of data … For now, data provenance is a broad big data concern. Here, our big data experts cover the most vicious security challenges that big data has in stock: Now that we’ve outlined the basic problem areas of big data security, let’s look at each of them a bit closer. Data leaks Databases may be considered a "back end" part of the office and secure from Internet-based threats (and so data doesn't have to be encrypted), but this is not the case. ScienceSoft is a US-based IT consulting and software development company founded in 1989. This may be a tricky thing to do, but you can always resort to professional big data consulting to create the solution you need. Troubles of cryptographic protection 4. Besides, outsiders can get access to sensitive information. Technically, NoSQL databases are continuously being honed with new features. The goal is to correlate a variety of criteria, including regulatory compliance mandate, application utilisation, access frequency, update cost and competitive vulnerability to arrive at both a value for the data and a ratio for determining justifiable security costs. The goal of the project is not to produce a report, but to build awareness and executive support for the treatment of sensitive data assets with technologies, policies and procedures that match with the regulations, the utilisation and the potential loss if the data assets were to be compromised. Most of the businesses that have held back from adopting the cloud have done so in … Problems with security pose serious threats to any system, which is why it’s crucial to know your gaps. Prioritizing big data security low and putting it off till later stages of big data adoption projects isn’t always a smart move. And just like we said in the beginning of this article, security is being mistreated and left in the background. The burden of avoiding data … But it doesn’t mean that you should immediately curse big data as a concept and never cross paths with it again. Many businesses are concerned with “zero day” exploits. You can reduce the risk of retaining sensitive customer data by removing the electronic and paper data from all systems and files. From security perspective, it is crucial because: This point may seem as a positive one, while it actually is a serious concern. Visit our corporate site. Big Data: Examples, Sources and Technologies explained, The ‘Scary’ Seven: big data challenges and ways to solve them, Big data: a highway to hell or a stairway to heaven? Since the data is not always generated within secure networks and the data at transit must be protected from threats in real-time. For a medical research, for instance, only the medical info (without the names, addresses and so on) gets copied. Laws concerning data privacy and security vary internationally. And although it is advised to perform them on a regular basis, this recommendation is rarely met in reality. Oh No, Security! The trick is that in big data such access is difficult to grant and control simply because big data technologies aren’t initially designed to do so. The problem here is that getting such access may not be too difficult since generally big data technologies don’t provide an additional security layer to protect data. Since its job is to document the source of data and all manipulations performed with it, we can only image what a gigantic collection of metadata that can be. All the parties involved should check these diagrams, and this process will itself raise awareness of both the value and the risk to sensitive data. We have to move beyond dealing with the crisis of the moment and focus on securing data holistically and consistently. Business managers need to classify data according to its sensitivity and its worth to the organisation so they can correctly evaluate and fund different levels of protection. And putting on all the precaution measures at a high speed can be too late or too difficult. We are a team of 700 employees, including technical experts and BAs.
