Security Architecture in Software Development

What is Security Architecture?

Security architecture is a strategy for designing and building a company’s security infrastructure. Troubleshoots data protection issues by analyzing processes, controls and systems. This multifaceted strategy has many elements such as security policy, risk management, and determination of controls and procedures. It is suitable for special cases such as network security, application security or business information security.

The purpose of network security architecture is to protect the organization’s network infrastructure using tools such as firewalls and intrusion detection systems. Application security architecture focuses on software security with an emphasis on secure coding methods and strong authentication systems. At the same time, the company’s information security architecture takes an approach to combine security measures with business objectives across people, processes and technology.

Types of Security Architecture
