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.

Jan 2015 - Jul 2015

Information Security Investigator

Cisco

Sydney, Australia

My role at Cisco was to provide senior technical leadership within the Cisco Managed Threat Defense (MTD) team. I was involved in finding the best ways to detect intrusions in our customers’ networks, and determining the best ways to detect them. I was hired to act as an escalation point for our US based MTD Analysts, providing them with additional insights into suspected attacks. I also provided input into the long term strategies that Cisco MTD should be working towards to ensure that they are able to compete in today’s market. An example is the integration of VERIS into our ticketing to improve the metrics that we can deliver to our customers. Another was development of the network detection playbook we used to catch bad guys, which listed the indicators of compromise we should look for and where to find them.

Apr 2014 - Jan 2015

Security Sme

Auckland

My role at Telecom was to roadmap, proof-of-concept, develop and architect a 1-3 year plan for security, and to ensure that we were utilising the latest security developments as best they could. I needed to juggle the long term vision of the enterprise architect with the direction the retail and corporate business units wanted to take the business, and factor in fixing the problems that hampered the operational security teams – and provided them with the latest techniques and strategies to respond to security incidents. It was my responsibility to develop a multi-year plan that improved Telecom New Zealand's security posture, and ensure that it aligned with work undertaken across Telecom New Zealand's business. This required closely following the latest trends in Security, and evaluating them for use within Telecom. As part of this process, I needed to involve all areas of the business, from our offshore departments to our enterprise facing business to our internally focussed departments. I needed to meet with business stakeholders, technical teams and subject matter experts within each area, who each feed information into the review process so that the security review was based on threats, vulnerabilities and business impacts that came from the participants themselves. In addition I created the Telecom Security Incident Response Team (T-SIRT) Incident Response Plan, integrated the VERIS framework into the corporate Ticketing System, and developed a Data-centric Security Model (integrating the Lockheed Martin Intrusion Kill Chain) to help target where we were missing Security Controls across our infrastructure. I also designed and architected the DNS Redirection Service, the Internal Sinkhole, the Enhanced Monitoring Solution and the deployment of Endace IDS sensors across the business, and was the lead architect developing our replacement SIEM.

Jul 2012 - Apr 2014

Senior Security Specialist

Telecom New Zealand

Auckland, New Zealand

My senior role within the Telecom Security Incident Response Team (T-SIRT) was to help develop and improve the types of services we could offer as part of T-SIRT. I created the first version of the Telecom Incident Response Plan, and developed our own T-SIRT Security Ticketing, extending it to leverage the VERIS incident classification framework. I was the lead developer of our open-source enterprise-wide IDS sensor design and managed to include detection functionality that many commercial products do not have. We implemented a Honeynet to improve our early warning detection, and included client honeypot technology in order to proactively detect infected internal machines. I designed a malware analysis environment for determining how malware works when we find some, and we began to design an internal penetration testing service in preparation for internally certifying some services the company offers. In addition to this development work I was responsible for reviewing vulnerability alerts from Secunia and AusCERT, and alerting management when one was critical enough to require urgent patching. I was also on constant standby to help out our 2nd Level Team if there was a security incident.

Jul 2007 - Nov 2012

Information Security Analyst

Auckland, New Zealand

My work at EDS was as a technical consultant for security matters. I worked as the only New Zealand based member of my Asia-Pacific team, and was responsible for providing customers with guidance on best practices, reviews of security designs and input into various process and procedure improvements. My role required me to have a good knowledge of EDS’s and our customer’s security policies and to make sure that any network designs that I reviewed were compliant with both. Being proactive and self-motivated was important, as my management were based in Sydney. Key Responsibilities: • Reviewed network designs for security issues and suggested improvements.• Performed vulnerability scans across various infrastructure.• Determined solutions to mitigate problems found during security audits.• Enforced network designs adherence to customers’ security policies.• Improved customers’ processes and documenting them.• Was a single national point of contact for security matters.• Was a member of the Asia-Pacific Threat and Vulnerability Management Team.

Jan 2007 - Jul 2007

Security Operations Specialist

Gen-I

Auckland, New Zealand

My role at Telecom Gen-i involved the constant monitoring of the security infrastructure (as part of a 24x7 support team), implementation of changes requested by customers, and troubleshooting connectivity issues where appropriate. I was responsible for resolving any incidents as quickly as possible, and with as minimal impact to the customer as possible. In addition to technical knowledge, the job required the ability to manage customer expectations, to work to a deadline, and to work cohesively and effectively with team members and other departments. My previous experience in a wide range of roles helped give me a fresh perspective on what customers were trying to achieve and how best to help them achieve it. My scripting and programming skills made our department more efficient, specifically by automating work, and by consolidating and refining documentation. Key Responsibilities: • Monitored security infrastructure used by some of New Zealand’s largest companies.• Rectified faults before they became a problem for customers.• Used and enforced the change control process.• Pro-actively audited customer implementations to improve efficiency and maintainability.• Ensured critical monitoring tasks were completed.• Created automated scripts to replace previously manual processes.• Improved the robustness of processes and documenting them.

Much of my responsibility was involved in the day to day monitoring, examination and control of possible security incidents. I was also responsible for detecting and reacting to possible network intrusions. Upgrading of Checkpoint Firewall-1/VPN-1, creation of a VPN and procedures for management of this system, improvement of the ISA Server, and introduction of web access controls were projects that I implemented or oversaw.
