  • timing attack

    A timing attack is a type of side-channel attack that exploits the amount of time a computer process runs to gain knowledge about or access a system.

  • tokenization

    Tokenization is the process of replacing sensitive data with unique identification symbols that retain all the essential information about the data without compromising its security.

  • total risk

    Total risk is an assessment that identifies all the risk factors associated with pursuing a specific course of action.

  • TrickBot malware

    TrickBot is sophisticated modular malware that started as a banking Trojan but has evolved to support many different types of attacks, including ransomware.

  • Trojan horse

    In computing, a Trojan horse is a program downloaded and installed on a computer that appears harmless, but is, in fact, malicious.

  • trusted computing base (TCB)

    A trusted computing base (TCB) is everything in a computing system that provides a secure environment for operations.

  • two-step verification

    Two-step verification is a process that involves two authentication steps performed one after the other to verify that someone or something requesting access is who or what they say they are.

  • What is a time-based one-time password?

    A time-based one-time password (TOTP) is a temporary passcode generated by an algorithm that uses the current time of day as one of its authentication factors.
