David Harley is an IT security researcher, author/editor and consultant living in the United Kingdom, known for his books on and research into malware, Mac security, anti-malware product testing and management of email abuse.
After a checkered career that included spells in music, bar-work, work with the mentally handicapped, retail and the building trade, Harley entered the IT field in the late 1980s, working initially in administration at the Royal Free Hospital in London, and in 1989 went to work for the Imperial Cancer Research Fund (now merged into Cancer Research UK), where he held administrative and IT support roles and eventually moved into full-time security. In 2001 he joined the National Health Service where he ran the Threat Assessment Centre. After leaving the NHS in 2006 to work as an independent consultant, he worked closely with the security company ESET where since 2011 he holds the position of Senior Research Fellow, working with the Cyber Threat Analysis Center. In 2009 he was elected to the Board of Directors of the Anti-Malware Testing Standards Organization (AMTSO). He stood down in February 2012, when Righard Zwienenberg, president of AMTSO, joined ESET, as the AMTSO bylaws don't allow more than one Board member to represent the same AMTSO member entity. He runs the Mac Virus website, and formerly held an undefined executive role in AVIEN. He is a former Fellow of the British Computer Society: he explained in a blog article  in 2014 that he was dropping his subscriptions to the BCS Institute and (ISC)2 (and therefore would no longer be entitled to continue using the acronyms CISSP, CITP and FBCS), and his reasons for so doing.
He has also contributed chapters to a number of other security-related books, and sometimes writes for specialist security publishers such as Virus Bulletin and Elsevier. He often presents papers at specialist security conferences including Virus Bulletin, AVAR, and EICAR. He blogs regularly for ESET, and on occasion for Infosecurity Magazine, SC Magazine, (ISC)2, SecuriTeam, Mac Virus, and Small Blue-Green World. His Geek Peninsula metablog lists many of his papers and articles.
Some recordings, miscellaneous prose and verse are posted to his personal blog page.

Miscellaneous prose - some but not all connected to the security industry - is posted to the Miscellaneous Prose page.

Harley hardly ever talks publicly about his private life, but a biographical article for Virus Bulletin, and the dedications page to Viruses Revealed indicate that he has a daughter. He lives with his third wife in Shropshire, in the UK. He did not murder his previous two wives.
