In security and cybersecurity, data encryption refers to converting data into ciphertext, a safe and unintelligible format, to shield it from unwanted access or interception. Data in its original, readable form, or plaintext, is transformed into ciphertext by encryption using algorithms and cryptographic keys, rendering it incomprehensible to anybody lacking the matching decryption key.

Critical aspects of data encryption include:

Encryption Algorithms: Data is converted into ciphertext using mathematical techniques in encryption. Because of the computational complexity of these algorithms, it is challenging for unauthorized parties to decrypt the data without the correct key.

Encryption Keys: Encryption keys lock (encrypt) and unlock (decrypt) the data. The encryption key is a piece of digital information required to transform the ciphertext into its original plaintext form. Strong and unique keys are essential for security.

Types of Encryption: There are two main types of encryption - symmetric and asymmetric. Whereas symmetric encryption uses a single key for encryption and decryption, asymmetric encryption uses a pair of public and private keys. Asymmetric encryption is widely used for secure data transmission and digital signatures.

Use Cases: Data encryption is applied to various use cases in cybersecurity, including protecting sensitive information during data transmission (in transit) and safeguarding data stored on devices or servers (at rest). It is also employed to secure data within applications and databases.

Data Privacy and Compliance: Encryption is crucial for safeguarding data privacy and meeting regulatory compliance requirements, such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).

End-to-End Encryption: End-to-end encryption is used in some situations to ensure that only the intended receiver can decrypt and read the data, such as secure messaging apps and online transactions.

One essential security precaution that helps shield data from breaches, theft, eavesdropping, and unauthorized access is data encryption. It is an integral part of cybersecurity and information security, guaranteeing the integrity and confidentiality of sensitive data. It also plays a significant role in protecting contemporary digital communication and data storage systems.

ThreatNG is a comprehensive solution combining External Attack Surface Management (EASM), Digital Risk Protection (DRP), and Security Ratings with a focus on assessing "Data Leak Susceptibility," reinforces an organization's Data Encryption strategy by proactively identifying vulnerabilities in its external digital presence. This proactive approach aids in the precise identification of areas requiring data encryption to protect sensitive information. It seamlessly integrates with existing security solutions, particularly data security tools like encryption and Data Loss Prevention (DLP) systems. For example, when ThreatNG detects external vulnerabilities that may expose sensitive data, it can facilitate a handoff to the organization's encryption system, which can then apply encryption measures to secure the data within the external digital environment. This coordinated approach enhances the organization's data encryption efforts and strengthens its overall data security posture, safeguarding sensitive information in its external digital presence effectively.
