No Secure Application Without a Security Concept

What Is an IT Security Concept?

An IT security concept is a key component of IT security management. Its purpose is to systematically identify, assess, and minimize risks. It also forms the foundation for all measures governing the handling of corporate and customer data. Beyond encryption technologies, an IT security concept covers access control and employee security awareness. With data breaches, system failures, and cyberattacks posing daily threats to corporate IT infrastructure, a well-structured security concept is more important than ever for ensuring systematic protection.

Why Does Your Company Need a Security Concept?

An IT security concept is essential for protecting your company against data loss, data misuse, and data theft. Professional security software is an important first step toward identifying critical zero-day vulnerabilities and strengthening your overall information security. At the same time, a well-defined concept helps ensure the integrity, availability, and confidentiality of your data.

Goals of a Successful Security Concept

A successful security concept defines, among other things, the IT security guidelines for your organization. To ensure comprehensive protection, it covers multiple areas, including data protection and network security. The following objectives are particularly important:

• Define the scope of information processes
• Identify and assess threats within the organization
• Determine the specific protection requirements of individual assets
• Establish the appropriate level of protection for sensitive data

How an IT Security Concept Works

An IT security concept defines how personal data may be collected, processed, and used. It also specifies which measures prevent the misuse of this information. By examining these aspects in detail, organizations can establish binding security policies across their operations.

How Do You Create a Security Concept?

Building an effective security concept requires several sequential steps:

• Start by defining the scope. Ideally, you create separate sub-concepts for different areas that together form a coherent whole.
• Conduct a static code analysis and structural analysis to understand how technical systems, processes, and information interact.
• Next, determine the protection requirements for each defined scope.
• In the modeling phase, incorporate the previous findings so you can extend security measures to existing interfaces as well.
• A baseline security check — for example, through a cloud pentest — reveals the current state of your security posture.
• Through targeted pentests, experts identify which risks are not yet fully addressed.
• Based on the analysis results, you can minimize the threat potential and maintain the desired level of security.

Example: Creating Secure Applications in Azure

A security concept is especially critical in the cloud application space. Azure offers both developers and organizations the tools to build a robust security concept, with multiple Azure services working together to integrate training, requirements analysis, and design. While Azure provides clear advantages for software developers, the underlying security framework is equally valuable for organizations. Notably, Microsoft consistently emphasizes the importance of reviewing the OWASP Top Ten, which provides detailed guidance on security vulnerabilities and IT security best practices.

What Are the Legal Requirements?

As IT security grows in importance, numerous legal requirements now govern the measures organizations must take. These regulations aim, among other things, to detect critical zero-day vulnerabilities early and protect sensitive data. For your security concept to meet these requirements, it must comply with applicable norms and standards while also accounting for your organization's individual circumstances. Key standards include the international DIN ISO/IEC 27001, which allows you to obtain certification for your information protection measures. Legal requirements extend beyond software security to encompass network security and data protection as well. Accordingly, the GDPR also shapes how your concept must be structured to safeguard personal data. While the legislator does not mandate cloud pentests or targeted static code analysis, both are important steps toward stronger security. Professional red teaming can provide optimal support for these strategies. The German Federal Office for Information Security (BSI) offers general recommendations in BSI Standard 200 on successful implementation, along with guidance on security methods and risk management. Organizations can use this practical framework to develop or refine their individual security concepts.

What Is the IT Security Act?

The IT Security Act, passed in 2015, aims to strengthen the security of IT systems. It applies to all organizations operating in critical infrastructure sectors, including transportation, energy, telecommunications, and the financial and insurance industries. Companies in these sectors are legally required to maintain adequate IT security. However, adhering to fundamental security standards benefits every organization — not just those in critical industries. Any company can gain significant value from pentesting, red teaming, and regular security assessments.

Are There Industry-Specific Aspects to Consider?

No single security concept fits every organization. Instead, you need to account for the specific requirements of your industry. A security concept in the healthcare sector, for example, demands far more comprehensive protection than one for a business that only processes basic personal data. While heavily regulated industries require end-to-end encryption as standard, the skilled trades sector tends to focus more on the secure exchange of sensitive customer information.

Who Is Responsible?

Responsibility for IT security always lies with executive management. While day-to-day creation, maintenance, and oversight may be delegated to other departments, leadership must actively endorse and champion security policies — including their implementation across the organization. Equally important is ensuring that employees understand IT security requirements. Fostering a healthy error culture within departments creates the right foundation, because only well-informed employees can respond effectively to security demands.

Who Develops and Maintains the Concept?

Developing an effective IT security concept requires a thorough understanding of all relevant business processes, combined with broad IT expertise. For this reason, creating the concept is never a one-person task — it is a multifaceted process that draws on knowledge from across the organization.

Is External Support Available?

Alternatively, you can engage a specialized IT security provider to create your concept. These experts bring deep IT security knowledge and can implement your requirements with precision. A key advantage of this collaboration is that the specialists provide ongoing advisory support and continue to maintain your concept over time. The result is a security concept that delivers lasting protection and remains fully compliant.
