About this video
Encryption is one of the primary techniques used to conceal data and evade detection, working by transforming readable information into an unrecognizable format through a cryptographic key. The encrypted data remains inaccessible without the corresponding decryption key, making it a powerful method for obscuring activity and protecting — or hiding — information from unauthorized eyes. This makes encryption not only a defensive tool but also a method attackers can exploit to cover their tracks.
Encryption applies across two distinct data states: data at rest and data in transit. Data at rest refers to information stored on a device or storage medium that is not currently moving or being transmitted, while data in transit refers to information actively traveling between systems or locations across a network. Recognizing how encryption functions in each of these states is critical for understanding both how it is used legitimately to protect sensitive information and how it can be weaponized to mask malicious activity from security monitoring and forensic analysis.

Key terms
- Encryption
- The process of converting readable data into an unreadable format using an algorithm and key to prevent unauthorized access.
- Data at Rest
- Data that is stored on a device or medium and not actively moving through a network, which can be encrypted at the disk, partition, volume, file, or database level.
- Data in Transit
- Data that is actively moving across a network or communication channel between two endpoints, as opposed to data sitting on a storage device. Protocols such as TLS are commonly used to encrypt data in transit so it cannot be read if intercepted.
