Data Security is securing your data from unauthorized access to ensure data privacy and prevent data misuse. In the cyber world, Hackers and attackers constantly threaten the security of your data by means of threats, such as the virus, phishing, and social engineering. These threats are usually directed to your digital devices, such as the computers and mobile phones, through the cyber world.
Importance of data security
If your digital devices are vulnerable to threats and do not have adequate security protection, your data will be compromised and no longer be secured. Therefore, it is important for each and every Internet users to be proficient about data security, and also have awareness about the emerging trends and paradigms of data security in today’s cyber world.
Data security measures
In today’s digital world, encryption is the key to protect your data. The main benefit of encryption is that only those who are authorized to access data will be able to read it. You may have confidential information that need not be exposed to all users. For example, your salary slip or any other financial document should not be exposed to other users.
Encryption is a process by which you can encode confidential information and messages so that only authorized people are able to access or read it. However, encryption does not prevent interception, but it does limit the accessibility of the message content to the interceptor. The information or message before encryption is referred to as plaintext and after encryption is referred as ciphertext.
Tip: Ciphertext can only be read after decryption.
An authorized recipient can decrypt the ciphertext only with the key provided by the person who encrypted the message.
Tidbit: Historically, encryption has been used by the military and governments to facilitate secret communication.
One of the important use is to encrypt data at rest. Data at rest is nothing but any data that is not frequently accessed or updated and stored in hard drives, USBs, or other backup devices.
These days, you may have seen numerous reports of confidential data, such as personal information, compromised through loss or theft of laptops or Universal Serial Bus (USB) drives. To mitigate these kinds of scenarios, it is very important to encrypt the data at rest.
In addition to data at rest, encryption should also be used to protect the data in transit against eavesdropping of network traffic by unauthorized users. Data in transit is nothing but any data that is being transferred through networks, such as the Internet, mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices, and bank automatic teller machines (ATMs). So make sure that your data is always protected irrespective of where it is by encrypting it.
