Background for this topic.

RSA is an asymmetric (public-key) cryptosystem, rather than the security conference that also uses the name. It uses mathematically related public and private keys: the public key can encrypt data for the holder of the private key, while the private key can create signatures that the public key verifies. Systems commonly use RSA to protect a symmetric session key or sign certificates and software, not to encrypt large amounts of data. Its security relies on the difficulty of factoring large numbers.

Safe deployment requires standardized schemes such as RSA-OAEP for encryption and RSA-PSS for signatures, suitable key sizes, protected private keys, and maintained cryptographic libraries. Textbook RSA and obsolete or incorrectly implemented padding can enable attacks even when the underlying mathematics is sound. A stolen private key can expose protected keys or invalidate trust, so key access, rotation, certificate revocation, and recovery procedures matter. RSA is also not expected to withstand a sufficiently capable quantum computer; organizations protecting long-lived secrets or trust anchors should account for migration planning.

Why Post-Quantum Cryptography Starts With Credentials

Today’s encrypted data, such as credentials, may no longer remain confidential in the future because the public-key cryptography protecting it will soon be broken by quantum computers. Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by

Why Honeytokens Are the Future of Intrusion Detection

A few weeks ago, the 32nd edition of RSA, one of the world's largest cybersecurity conferences, wrapped up in San Francisco. Among the highlights, Kevin Mandia, CEO of Mandiant at Google Cloud, presented a retrospective on the state of cybersecurity. During his keynote, Mandia stated: "There are clear steps organizations can take beyond common safeguards and security tools to strengthen their
