Malware and virus entries in the NIST Computer Security Resource Center glossary

Primary institutional glossary, Definitions: intentional harmful purpose and unauthorized effects on data/systems. Virus entry csrc.nist.gov/glossary/term/virus distinguishes attachment to host programs/files and self-replication. Direct virus-page fetch timed out; the underlying official NIST SP800-83r1 section2.1, nvlpubs.nist.gov/nistpubs/specialpublications/nist.sp.800-83r1.pdf , independently verifies the host-file replication definition. Only high-level terminology used; no execution, infection or concealment procedure reproduced.
