With recently augmenting hacking attacks and data leakages, it now seems that critical data and sensitive information has never been as much vulnerable as it is today. Also, with all aspects of businesses becoming increasingly digitized; companies are now more and more relying on 3rd-party solutions, including antivirus software, DLP solutions, and other such solutions for keeping their data secure. Sensitive information can come in various forms depending upon the type of business sector it is a part of. It can be credit card information, patient medical records or even the social-security-numbers, but, irrespective of its actuality, it can be distinguished into 3 different types: the first one being the data at rest, the second one is the data in use and third of these is the data in motion. These 3 types of data have different levels of their vulnerabilities and also different challenges while talking of their security.
Let us first understand what data at rest is. Data at rest is actually that static data which is stored on the hard drives and which is archived or which is not so often accessed or the data that has been modified. Data in use, on the other hand, refers to that data, which is frequently been updated by more than one users inside a network and the data which is very much active. Thirdly, the data in motion is that data, which has been transferred outside the organizational network and which is subject to 3rd party services for which security is never guaranteed and in fact is always a great concern. Most Data Loss Prevention i.e. DLP solutions address these data dangers which are faced by the data in motion and check for any breaches and human errors during transits.
It is a widespread misconception that this data at rest is much safer than the data in motion as it’s not that much exposure to potential risks of varied internet transfers. Most of the cybercriminals and hackers don’t need any physical access to any computer for its data to be compromised. All they require is a minor vulnerability, which they can easily exploit, whether it is a technical one or maybe a human one.
More often than not, the antivirus software used conventionally as well as firewalls etc., are all used for protecting this data at rest. But, they don’t guarantee any such safety from phishing attacks. Let’s say, for example, they can target any particular persons, corrupt one of their workstations and then they would proceed towards attacking rest of the organizational network. Inattention is a big cause of data leaks in today’s scenarios and this is the most significant danger to this data at rest. Forgotten USB sticks in cars or at airports and forgotten laptop bags at airports or cars are some of the common incidences that happen in today’s dynamic corporate business environments often requiring travel, multiple meetings off-site as well as presenting presentations etc. Dissatisfied employees, who have been looking towards leaving a particular organization, are also known for copying sensitive information and significant data for carrying it to their next company they get employment in.
It is important for firms today to look beyond such protection methods and explore more and more complex means for addressing such cloud security issues that have been engulfing data at rest. CASB solutions by CloudCodes, through their useful modules, can helps protect your data at rest.
Cloud security is important and a great requirement that every organization today has to consider so as to avoid getting harmed by hackers, cybercriminals and attackers or risk the public releases of their sensitive data & information through leakages/thefts. It’s pretty clear that if we protect only 1 type of such data, whether data in motion or data in use or may be both and ignore data at rest completely, then it may lead to some very disastrous consequences. It is thus important that firms look for an all-inclusive approach and find all-inclusive solutions to deal with all types of sensitive information, irrespective of its state.
