A security engineer designs, builds and maintains the controls that protect an organisation's systems, applications and data from attack. Companies often hire one when enterprise customers, audits or rapid growth raise the stakes.
DevSecOps is the practice of building security checks into everyday software delivery. Code, dependencies and infrastructure are tested automatically on every change instead of being reviewed only before release.
Threat modeling is a structured way to identify what could go wrong with a system's security during design. Teams then decide which risks to mitigate before code is written.
Cybersecurity is the practice of protecting systems, networks, applications and data from unauthorised access, attack and damage. It combines technology, processes and people to prevent incidents, detect them early and recover when they happen.
Penetration testing is an authorised, simulated attack on a system to find exploitable weaknesses before real attackers do. Testers work within an agreed scope and report what they reached and how to fix it.
