The concept of communications security is crucial in today’s world, where sensitive information is exchanged daily through various messaging apps. Encryption is one way to ensure user privacy while using apps like WhatsApp, Signal, and Telegram. However, a security by design approach is also essential for the future of applications. While it can be unprofitable currently, companies like Kaspersky believe that security by design should be considered throughout the project process from conception to implementation.
End-to-end encryption (E2EE) complements security by design by providing an additional layer of security and privacy for users. However, E2EE can limit visibility in certain investigations, such as those related to criminal activities like terrorism or drug trafficking. This has led some authorities to question the use of E2EE and urge technology companies to opt for a security-by-design approach instead to facilitate investigations.
Messaging apps that use E2EE have faced criticism from authorities for making it difficult to access user communications for investigative purposes. The European Union and the United Kingdom have questioned the use of E2EE due to concerns about potential misuse by criminals or terrorists. While E2EE protects the content of messages exchanged between users, security by design ensures that security measures are incorporated into applications from the beginning.
Balancing the need for privacy with the requirements of law enforcement remains a challenge for technology companies and authorities in the evolving landscape of communications security. Ultimately, both approaches are important in enhancing the security and privacy of communications while ensuring that legal requirements are met.
