What Does a Security Engineer Do?

Security engineers act as the first, and most important line of cyber defense for a company. They design and implement security measures that protect an organization’s computer networks, systems, and data and assess vulnerabilities and weaknesses to prevent the loss of information or the slowdown of business.

Security engineers use a variety of software applications and tools to monitor intrusion and detect cyber threats. They maintain and upgrade networks and systems to protect businesses and train employees and staff to report and avoid phishing techniques and other potential scams.

The role requires a strong understanding of network protocols, firewalls, encryption, operating systems, and cybersecurity techniques and best practices. In addition to these hard skills, security engineers should be excellent communicators who can explain technical concepts to non-technical management and staff.
