When the word “Data security” is read, the first thing that comes to our mind is what is data? So to start with simple words all the documents in a sorted manner are known as data in technical terms. This data can be either in physical form or in virtual form. So here we talk about the virtual data as it is less space consuming. And if in case it is space consuming, it is in abstract form which can neither be seen nor be touched. It can only be acknowledged by a person if he or she is associated with it.
In today’s world, we are too much involved with the virtual world i.e. our cloud-based data storage. This is basically a kind of data storage which is not in the form of papers but in a virtual manner. But this data needs to be safe and secure to keep it away from misusers and not only that but to maintain it in such a way so that it is easy to access. Time flies and technology has also taken its steps ahead from the previous levels and thus the need of data security is at its peak.
Data security means the protection of data which is in digital form. It is mainly needed to protect it from unwanted actions such as cyber-attacks or data breach. Also to protect it from data destructions. These are the reasons of why the data needs to be secured.
There are many different types of technologies for data security:
- Disk encryption
- Data Masking
- Data erasure
- Secure Logic Migration and Execution Technology
- Data Traceability Technology
- Authentication and Identity
It is a method of protecting the data by converting it into unreadable code which is not easy to decode by unauthorized people. By this method, it encrypts each and every bit of data which is stored on the hard disk.
This is the most commonly used method of data security. In this method the stored data is copied or archived and used to restore original data after an incidence of data loss.
In this method of data security, the format of the data is maintained, while the values are changed. In this case, the data is altered in the number of ways by either encrypting or substitution of characters or word.
Data erasure is a method in which the data stored in the hardware store is overwritten by zeroes and ones so that the data is not retrieved. This leads to total data destruction and it is not possible to retrieve the lost data.
SECURE LOGIC MIGRATION AND EXECUTION TECHNOLOGY
Another way of securing your data by moving away some or all your data to new location or new storages which are modernly equipped. This method is mainly used by companies to secure their data by updating their method of securing. In this case, the data is mainly migrated to different cloud locations.
AUTHENTICATION AND IDENTITY
Identification of an authorized person to access the confidential data is another secure and safe technology for the protection of data. This is the most implemented technology for securing data.
Also, there are several types of data security, such as:
- Network layer security
- IPsec Protocol
(a)Authentication Header(AH) and Encapsulating Security Payload(ESP)
(b)Portable data security
- Email Security
As data security is in demand, so are the jobs. The employment in this field is vast and yet growing. If one opts to go for data security, he/she can be an employee for this job.
The various jobs available for this are mentioned below:
- Chief Information Security Officer(CISO)
- Security Director
- Security Architect
- Security Manager
- Security Engineer
- Malware Analyst
- Security Consultant
- Computer Forensics Expert
- Security Specialist
- Incident Responder etc.
A great surge in digital threats like crypto miners, ransomware and DDoS attacks have been faced in the recent pasts which have led to awareness among common people. Also, people are getting more used to the virtual world as compared to real world.
We have seen many scenarios which have problems whenever the data is misused. Either there is a great drop in the market or there are many people out there who are very much affected by these incidents. Also, the level of education is growing and people are educated in reference to this topic.
As a result, we now know what is data and how its security matters. Also as the time passes and the upcoming generation will have much more knowledge in context to data security. And as and when the time will demand growth in the field of data security, there will be much more technologies discovered for securing data.
