Background for this topic.
Encryption transforms readable data into ciphertext using an algorithm and a key, so someone who obtains the ciphertext cannot normally understand it without the required key. It protects confidentiality for data in transit, such as traffic between services, and at rest, such as files, databases, and backups. Encryption does not by itself prove who sent data, prevent tampering, or protect plaintext displayed on a compromised endpoint.
Its security therefore depends on implementation and key management. Attackers may target stolen, exposed, or overprivileged keys, weak algorithms or protocols, poor randomness, and systems that decrypt data unnecessarily. Use modern, authenticated encryption where appropriate; protect keys separately from encrypted data with tightly limited access, rotation and revocation procedures, and monitored use. Verify that encryption covers relevant backups and internal service links, while recognizing that lost keys can make recovery impossible and that encrypted traffic may still reveal metadata such as timing or endpoints.
Apple, US Took Hard Line Against British DemandThe U.K. government is reportedly set to reverse course on requiring smartphone giant Apple to give police access to device data stored as backups in the California company's cloud service. "The Home Office is basically going to have to back down," a British official said.
Proton has launched a new tool called Lumo, offering a privacy-first AI assistant that does not log user conversations and doesn't use their prompts for training. [...]
The acquisition gives the British cybersecurity solutions provider more insights into encrypted network traffic and additional decryption capabilities.
Startup Mira Security Will Offer Insights on Encrypted Network Traffic, DecryptionDarktrace purchased a network traffic visibility startup to get insights from encrypted network traffic and decryption for customers in regulated industries. Mira Security will provide organizations with deeper, more comprehensive visibility across on-premises, cloud and hybrid environments.
Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected
