Profile bio

About Terry Macdonald

I am passionate about Threat Intelligence Data Sharing. I believe the only way we can combat malware and detect attackers is to share the threat data we have with other defenders. Crowd sourcing attack data, automating processing of that threat data to filter the noise, detecting all the available indicators of compromise from within the kill chain and sharing them with the incident response community are the only way we'll be able to find attacks against our own networks. For this reason I'm an active contributor to STIX/TAXII/CybOX/MAEC/CAPEC, and to a lesser extent CIF.I'm also very interested in the use of Incident Categorisation protocols such as VERIS to improve sharing of Incident Response metrics, to provide better information for risk analysis, show value of new security tools, and target security investment to where it's needed most. I've presented on the subject at the ISIG meeting in Auckland.I'm an active member of the NZ Internet Task Force (NZITF), and believe that NZ and Australian are in a unique place to protect 90% of the Internet Community by sharing threat intel between its top 6 ISPs. This would change how NZ and Australia are viewed by potential attackers, and would have a real benefit to the population of both countries. It’s difficult to do - but not impossible. I relish challenges like that.

Listed skills include Security, Network Security, Information Security, Computer Security, and 45 others.
