   Built-in self-test (BIST) and Design For Test (DFT) techniques add circuitry (logic) to the chip intended to help verify that the chip, as built, implements its functional specification. The extra logic monitors input stimulus and internal signals or memory states, generally by computing checksums or by exposing internal registers via a ...

6. Ransomware - Wikipedia

   en.wikipedia.org/wiki/Ransomware

   Ransomware attacks are typically carried out using a Trojan, entering a system through, for example, a malicious attachment, an embedded link in a phishing email, or a vulnerability in a network service. The program then runs a payload, which locks the system in some fashion, or claims to lock the system but does not (e.g., a scareware program).

7. Vulnerability (computer security) - Wikipedia

   en.wikipedia.org/wiki/Vulnerability_(computer...

   A penetration test attempts to enter the system via an exploit to see if the system is insecure. [46] If a penetration test fails, it does not necessarily mean that the system is secure. [47] Some penetration tests can be conducted with automated software that tests against existing exploits for known vulnerabilities. [48]
