DATA SECURITY DEFINITION: Data security is more important today than ever. At a time when we are constantly online and almost all of our lives are connected to the Internet, our data has become a sensitive and valuable asset. Companies like Google and Facebook earn incredible amounts with our private information. And if the data falls into the wrong hands, it can have fatal consequences. Nevertheless, many people do not even have the topic of data security on their screens. Even small steps can help to better protect your data. In this blog article we not only show you the data security definition, but also explain how you can better protect your data online.

DATA SECURITY : A valuable asset in the digitized world

No matter whether you want to book a train journey, check your account balance or just want to check the latest posts from your friends on Instagram – today you have logins for all areas of your life. Our data buzzes everywhere on the net. Most of them ignore the topic of data security. “Nothing will happen,” is the general motto.

But then you hear about a big data scandal again and start to ponder: Maybe I should take a closer look at the security of my data? Which platform can actually do what with my data? Would it be a good idea not to use the same password on every platform ? Finding the answers to these questions is not that easy.

The fact is: data is a valuable asset in the digitized world. Companies like Facebook or Google earn a lot of money from their users’ data. And we give them to you voluntarily, in the case of Google, for example, by using Google search, Google Drive or a Gmail account. The services are supposed to be free and offer us a lot of convenience – but also at the price of our data. This is how the Group learns a lot about us: what moves us, what is going on in our lives, what we buy. It is not for nothing that Google is also called the data octopus. And, in turn, Google uses this extensive knowledge to place targeted ads. The same naturally applies to many of the large corporations.

The situation becomes even more precarious if criminals illegally gain access to our data and then make money with their earnings or even use them for identity theft . In the past, some large companies such as Adobe, Ebay or the financial services provider Payment Systems were affected by data theft on a large scale. As you can see, not all companies rely on the security of their user data or the measures are not sufficient to prevent subtle criminals. A study by the Federal Office for Information Security (BSI)According to 43 percent of the companies surveyed, they had been victims of a successful cyber attack. Another 43 percent successfully fended off a cyber attack.

DATA SECURIty: We are responsible for our data

Of course, companies have a duty to handle our data carefully and to protect it as best as possible. But as you can see from the numerous incidents in recent years, this does not always succeed. That is why it is up to us to be vigilant when dealing with our data and to think carefully about where we disclose which information from us. However, many make the mistake of handling their private information too carelessly.

So you are quickly tempted to enter your data for a supposedly free goodie – and your name, email address or other information from us is floating around on the Internet without us being able to say exactly who has access to it now. And many smartphone apps also spy out personal data that they actually don’t need. In June 2019, for example, it became known that the Spanish Football League’s official app, using the microphones and location data of smartphone users, was able to determine that they were caught in a restaurant that was showing illegal pay TV . The 10 million users who downloaded the app unwittingly became spies for the company.

The reasons why we handle our personal data on the Internet so carelessly lie somewhere between ignorance and lack of interest. On the one hand, the topic seems so complex that as a normal consumer and Lieschen Müller you can’t really see through it. On the other hand, many of us are still closing our eyes to the risks and just hoping that it won’t hit us personally.

But the chance that you will be affected by data theft yourself is not as small as you might think. Perhaps you have also been the victim of a data theft without knowing it? The fact is: a quarter of PEOPLE have been affected by identity theft before. With the Identity Leak Checker of the Hasso Plattner Institute, you can check, whether you belong.DATA SECURITY DEFINITION

But even if you’ve been lucky and spared so far, you shouldn’t take the issue of data security lightly. The more digitalization determines our lives, the greater the risk that our personal data will fall into the wrong hands. It is high time that we as private individuals also think about how we can best protect our personal data.

what is it anyway?

The definition of data security is quickly clarified: The term data security is about the general protection of all data of a person or a company. This must not only be the classic data such as name, date of birth or the like, but also includes data without personal reference such as construction plans.

The goal of data security is to take appropriate measures to ensure the protection of all data against manipulation, loss and other threats. These measures can be either technical or organizational in nature.

What is the difference between data protection and data security?

In everyday life, the terms data protection and data security are often used interchangeably. But as is the case in everyday language use, there are subtle differences that distinguish the two expressions. DATA SECURITY DEFINITION

Data protection is by definition a right of every citizen. In contrast to data security, data protection is about protecting personal data such as name, email or telephone number. If this right is disregarded, personal rights and fundamental rights of people are violated. Data security and data protection can not be without each other, because they are mutually dependent.

With the entry into force of the new General Data Protection Regulation in 2018, better known as the GDPR , everyone is talking about data protection again. With the GDPR, data protection in the EU was completely redesigned.

Why is data security so important?

Thanks to the examples in the introduction, you probably have an idea why data security is so important. The data we leave on the Internet says a lot about us and our lives. And honestly: Who wants them to get into the wrong hands and that strange people (sometimes intimate) know details about our life? On the street you wouldn’t give your account details or your address to anybody, why on the internet? DATA SECURITY DEFINITION

That’s why I always keep in mind: With communication technologies, there is usually a risk that data is not secure due to technical defects or due to inattentiveness. Nobody is perfect, not even a system. And the deeper digitalization is rooted in our lives, the greater the risk of data theft. That is why data security is more important than ever. Because once damage has occurred, it is often too late. The motto here is very clear: caution is better than forbearance.

How can I ensure my personal data security?

You are now wondering how you can specifically ensure your personal data security. The good news is that each of us can significantly increase the security of our data on the web with just a few simple steps. And you don’t need extensive IT know-how, you just have to follow a few rules, which we will introduce to you in more detail below.


Cost use Bill

First of all, the obvious: Every time you enter personal data on the Internet, ask yourself exactly: Is this really necessary? At what price do I share my details with a company? Is the effort and benefit really worth it, or can I not do without the product for the benefit of the security of my data? DATA SECURITY DEFINITION

A good example is the baby programs of large PEOPLE drugstore chains. Before you register yourself and your child, listen to yourself for a moment and ask yourself whether your sensitive data is really worth exchanging for a few cream and diaper samples, which are often only worth a few euros. And honestly, most of it ends up in the trash anyway. But what remains is your data, which the company in question can use immediately until you expressly object to the use of the data. Such examples can be found in large numbers in everyday life – and if you think twice about it, you often come to the conclusion that the cost-benefit ratio is not given.

If you enter your data somewhere, it is best to only provide the mandatory information, which is usually marked with an asterisk. Just leave everything else out. Because where no data has been given, it cannot be stolen.

Look for security certificates when surfing the web

Better safe than sorry. This also applies when surfing the Internet. You can significantly reduce the risk of data theft by being vigilant and keeping your eyes open while surfing the web. Always check whether the visited pages have a security certificate, because smaller pages without such a certificate are particularly susceptible to hacker attacks. You can usually recognize this by a small icon next to the address bar in your browser. You can also visit websites with an https: // in front of the web address without hesitation. Especially with downloads, you should check carefully beforehand whether the source of the download seems serious to you.

In general, you should note: If something strikes you as strange, it is best to listen to your feeling and never give sensitive data on a page where your alarm bells are ringing “CAUTION” – usually the first feeling is confirmed when you take a closer look.

Especially when traveling, you should definitely keep this in mind, because then the security of your data is often particularly at risk. Whether on the train, in many hotels or in restaurants, free WiFi is available everywhere. While this is comfortable, it is unfortunately not entirely safe. Because these networks are often unprotected, so that unauthorized persons could easily access the transmitted data. A little tip: If you are traveling a lot, our self-learning course “Data security while traveling” could be something for you.

Choose strong passwords

Many of us probably have two or three standard passwords that we use for all kinds of logins. No wonder, because nowadays we are registered with so many platforms that it is impossible to remember all passwords. Don’t worry, you’re not alone with that. In a Statista survey , Internet users were asked about their passwords: 59 percent of those surveyed stated that they used the same password for several services. Just under half (44 percent) even feel stressed by a high number of passwords.

Nevertheless: Anyone who always uses the same simple password will be hacked sooner or later. That’s why you should make your passwords secure. But what is a secure password? In general, the longer a password, the better. However, it should consist of at least eight to twelve characters. Also pay attention to combinations of characters, use small and large letters, special characters and numbers. Then the password is much more difficult to crack. In addition, you should never use words from normal language use, names or dates of birth from your immediate vicinity. These are much easier to guess than randomly created passwords. You can also find more detailed tips on the correct password in our blog article on password security .

The so-called 3-step principle for password security is also helpful for categorization . The first stage is about not wasting a good email address on unimportant accounts. A not so secure password is also sufficient here. The second stage is about semi-important approaches that are not about money. The passwords should be secure and unique at this level. Level 3 is really important online access. The password must be very good, unique and particularly secure.

How to remember all the passwords? Quite simply, there are so-called password management systems that can help you with storing passwords. Take a look at Lastpass , Secure Safe or KeePass, for example . These tools can also help you create a secure password.

One last tip on passwords is the so-called authenticator apps. Criminals then not only need the user name and password, but also the smartphone linked to the app. Authenticator apps increase security enormously, especially on websites or apps that involve credit card data.

Back up your data regularly

When was the last time you backed up your smartphone or computer? Oops, was that a while ago? Well, then do that directly for the next weekend. Backing up your data will not take long, but in the unlikely event of an incident, you will be very happy to have invested a few minutes in making a backup.

This is all the more important in companies because digital computing systems and possibly also mobile devices are used here, on which company-internal information, accounting data and also various customer data are stored. Unwanted changes in this data up to the loss of all data can threaten the existence of a company. Therefore, all relevant data should be backed up appropriately. Which type of data and system backup is chosen depends on the individual situation in the individual company. 

Conclusion: data backup is more important than ever

As you’ve seen, DATA SECURITY DEFINITION is more important than ever these days. We are always online and leave our mark on the net while surfing. With online shopping, online banking and Co., we entrust companies with our most sensitive data. And the more we connect our lives, the more the Internet of Things grows and cloud-based voice services such as Alexa, Siri or Google Home are used, the more important the topic of data security becomes.

We cannot rely solely on companies to adequately protect our data. It is also our responsibility to handle our data carefully and carefully and to protect it as best we can. It starts with the assignment of secure passwords, goes through the well-considered input of sensitive data and ends with additional security measures, which we have presented to you in this text. Nobody can guarantee you 100% security, but you can do a lot to ensure that your data is safe online.
