Harry McLaren is a managing consultant at ECS who gives a presentation on cybersecurity engineering. Cybersecurity engineering involves building systems, deploying configurations, integrating systems, and developing solutions to protect against, detect, and respond to threats. It is important for engineering projects to consider people, process, technology, the end user, support requirements, and how the solution fits within the business and IT strategies. The presentation provides examples of scenario walkthroughs and best practices for engineers, such as using automation, version control, containers, and cloud technologies.
