From AAA Services to Zero Trust Network Access, Portnox’s cybersecurity center covers every inch of network security, data protection, cyber threats, and beyond—from A to Z.
What is cipher block chaining? Cipher Block Chaining (CBC) is a mode of operation for block ciphers (like AES or DES) that improves security by making the encryption of each...
What is JIT access? JIT access is a security strategy that grants temporary, time-bound access to systems, applications, or data only when needed, and only for as long as needed...
What is a machine identity? A machine identity is a digital identity assigned to a non-human entity — such as a computer, server, application, virtual machine, container, or IoT device...
What is an elliptic curve cryptosystem? An Elliptic Curve Cryptosystem (ECC) is a type of public key cryptography based on the algebraic structure of elliptic curves over finite fields. It’s...
What is Zero Standing Privileges (ZSP) in cybersecurity? Zero Standing Privileges (ZSP) is a modern security concept rooted in the principle of least privilege and just-in-time (JIT) access. At its...
What is the ACME protocol and how does it work? The Automatic Certificate Management Environment (ACME) is a protocol developed by the Internet Security Research Group (ISRG), primarily to automate...
