Security engineering is the process of incorporating

.

In one form or another, security engineering has existed as an informal field of study for several centuries. For example, the fields of locksmithing and security printing have been around for many years. The concerns for modern security engineering and computer systems were first solidified in a RAND paper from 1967, "Security and Privacy in Computer Systems" by Willis H. Ware.^[2] This paper, later expanded in 1979,^[3] provided many of the fundamental information security concepts, labelled today as Cybersecurity, that impact modern computer systems, from cloud implementations to embedded IoT.

Recent catastrophic events, most notably

, have made security engineering quickly become a rapidly-growing field. In fact, in a report completed in 2006, it was estimated that the global security industry was valued at US $150 billion.

Security engineering involves aspects of

Some of the techniques used, such as fault tree analysis, are derived from safety engineering.

Other techniques such as cryptography were previously restricted to military applications. One of the pioneers of establishing security engineering as a formal field of study is Ross Anderson.

Qualifications

No single qualification exists to become a security engineer.

However, an undergraduate and/or graduate degree, often in

, or Certified Physical Security Professional are available that may demonstrate expertise in the field. Regardless of the qualification, the course must include a knowledge base to diagnose the security system drivers, security theory and principles including defense in depth, protection in depth, situational crime prevention and crime prevention through environmental design to set the protection strategy (professional inference), and technical knowledge including physics and mathematics to design and commission the engineering treatment solution. A security engineer can also benefit from having knowledge in cyber security and information security. Any previous work experience related to privacy and computer science is also valued.

All of this knowledge must be braced by professional attributes including strong communication skills and high levels of literacy for engineering report writing. Security engineering also goes by the label Security Science.

Web applications

According to the Microsoft Developer Network the patterns and practices of security engineering consist of the following activities:^[5]

• Security Objectives
• Security Design Guidelines
• Security Modeling
• Security Architecture and Design Review
• Security Code Review
• Security Testing
• Security Tuning
• Security Deployment Review

These activities are designed to help meet security objectives in the

Physical

• Understanding of a typical threat and the usual risks to people and property.
• Understanding the incentives created both by the threat and the countermeasures.
• Understanding risk and threat analysis methodology and the benefits of an empirical study of the physical security of a facility.
• Understanding how to apply the methodology to buildings, critical infrastructure, ports, public transport and other facilities/compounds.
• Overview of common physical and technological methods of protection and understanding their roles in
  deterrence
  , detection and mitigation.
• Determining and prioritizing security needs and aligning them with the perceived threats and the available budget.

Product

Product security engineering is security engineering applied specifically to the products that an organization creates, distributes, and/or sells. Product security engineering is distinct from corporate/enterprise security,^[6] which focuses on securing corporate networks and systems that an organization uses to conduct business.

Product security includes security engineering applied to:

• Hardware devices such as cell phones, computers, Internet of things devices, and cameras.
• Software such as operating systems, applications, and firmware.

Such security engineers are often employed in separate teams from corporate security teams and work closely with product engineering teams.

Target hardening

Whatever the target, there are multiple ways of preventing penetration by unwanted or unauthorized persons. Methods include placing

to authenticate users.
