The Importance of Data Encryption in Cybersecurity

Encryption is a cybersecurity solution that safeguards sensitive information by using one-of-a-kind codes to jumble it and render it unreadable by outsiders. Encryption makes guarantees that private information held by an organisation is secure despite a data breach, even if attackers manage to get beyond the firewall.

Businesses are gathering a lot of sensitive user data, therefore, they need to make sure that all of the data they have is encrypted to stop it from falling into the hands of unwanted parties.

The encryption of data is an easy operation. The plaintext data is converted into ciphertext, or unreadable data, using an encryption key and a specified encryption technique. Attackers will not be able to view the information even if they manage to get past the network security measures since the jumbled data can only be decoded with the associated encryption key.

Websites utilise Secure Sockets Layer (SSL), a kind of data encryption, to safeguard sensitive user information. It stops hackers from gaining access to private user information that is sent to and from the website. The URLs of websites that have incorporated SSL security display the padlock sign and use "https" rather than "http" for their link addresses. The usage of SSL ensures that sensitive user data is safeguarded and that online transactions are encrypted for the website's users.

But are businesses really required to spend money on data encryption for their online procedures and transactions? Here are four arguments in favour of it.

  1. Data in transit is unsafe

Communication lines are easily vulnerable to hacker attacks, which allow them to intercept data in motion. Data encryption prevents sensitive information from being stolen in transit using data extraction methods like brute force.

  1. Security risks are changing.

Businesses need to ensure that attackers won't be able to read their data should their firewalls get penetrated since attackers are continually developing new techniques to get past even the most stringent cybersecurity measures. Attackers cannot access vital data thanks to data encryption.

3. Applications that are not certified may reveal sensitive data.

Installation and usage of specific unapproved internet tools and resources have the potential to introduce invasions and compromise security. Your personal information can be exposed in this situation to malicious internet actors. This is avoided via data encryption, which makes sure that your personal information is encrypted and hard to decipher by unauthorised users.

4. The business of hacking

Companies are always attempting to access the private data of their rivals in order to understand their upcoming business strategies due to competition and commercial rivalry. As a result, the hacking industry has expanded, with tech-savvy individuals breaking into businesses' internet systems in exchange for money. Data encryption will make sure that, even if someone manages to get past your security measures, they won't be able to read, comprehend, or utilise your data.

Data encryption is an excellent strategy for organisations to use in order to safeguard their data from internet intruders. Your crucial data is kept secure since it is scrambled so that unauthorised users without the encryption key cannot decipher it.


What are the benefits of encryption?

Protecting the secrecy of digital data that is stored on computer systems or sent over the internet or any other computer network is the main goal of encryption.

The requirement to adhere to compliance rules frequently drives the use of encryption in addition to security concerns. Sensitive data should be encrypted, according to a variety of organisations and standards bodies, to stop unauthorised parties or threat actors from accessing it. As an illustration, the Credit Card Industry Data Security Standard (PCI DSS) mandates that businesses encrypt consumers' payment card information when it is both kept at rest and sent over open networks.


What are the disadvantages of encryption?

While encryption is intended to prevent unauthorised parties from understanding the data they have obtained, in some circumstances, encryption can also prevent the data's owner from having access to the data.

Since the keys needed to decrypt the encrypted text must be present someplace in the environment, key management is one of the most difficult aspects of developing an enterprise encryption strategy since attackers frequently know where to look.

There are several recommended practises for managing encryption keys. It's just that key management makes the backup and restore procedure more difficult overall. The time it takes to retrieve the keys and add them to a fresh backup server in the event of a big disaster might lengthen the time it takes to begin the recovery process.

It is not sufficient to have a key management system in place. Administrators must devise a thorough strategy for safeguarding the key management system. This usually entails keeping it up separately from other data and storing backups in a way that makes it simple to access the keys in the case of a major catastrophe.
