The Fundamental Importance of an Integrated Security Concept for Banks

Owing to their role as custodians of assets and sensitive data, banks are a prime target for criminal activity. This encompasses not only traditional physical robberies but, increasingly, also complex cyberattacks aimed at data theft, sabotage or extortion. The Bitkom study "Wirtschaftsschutz 2025" shows that the damage caused by data theft, sabotage and industrial espionage in the German economy has risen to 289.2 billion euros, with cyberattacks accounting for 70 percent of this damage. These figures underscore the urgency of a robust, integrated security concept that takes into account all potential attack vectors.

Such a concept must go beyond merely reacting to incidents and prioritise preventive measures. It serves not only to protect tangible and intangible assets but also to ensure business continuity and maintain customer trust. Without a well-thought-out, regularly updated security concept, financial institutions expose themselves to considerable financial, reputational and legal risks. The complexity of the threats calls for a strategic approach that links technical, organisational and personnel aspects to ensure comprehensive resilience. PLANATEL® has supported financial institutions in developing such strategic concepts for more than 34 years.

Developing a security concept for banks is inextricably linked to a complex web of legal requirements and supervisory rules. In Germany, the Minimum Requirements for Risk Management (MaRisk) and the Supervisory Requirements for IT in Financial Institutions (BAIT), both issued by the Federal Financial Supervisory Authority (BaFin), are particularly decisive here. MaRisk gives concrete form to institutions' organisational obligations under Section 25a of the Kreditwesengesetz (KWG) and sets out a holistic framework for managing all material risks. The BAIT, in turn, specify BaFin's expectations for banks' IT security and cover topics such as IT strategy, information risk management, information security management and IT operations.

In addition, European directives and regulations such as the NIS2 Directive and the Digital Operational Resilience Act (DORA) are becoming increasingly relevant for strengthening the financial sector's resilience against cyberattacks. These regulatory frameworks require financial institutions not only to implement technical security measures but also to establish robust governance structures, contingency concepts and reporting obligations. Compliance with these requirements is crucial for avoiding sanctions and securing the operating licence. A legally compliant security concept must continuously reflect and adapt to these dynamic regulatory requirements, which calls for specialised planning expertise.

Structural and Technical Installation Systems for Physical Security

A bank's physical security forms the first line of defence against burglary, theft and vandalism. A comprehensive security concept integrates a range of technical installation systems here, coordinated with one another. These primarily include intrusion detection systems, planned and installed to DIN VDE 0833-3, to detect and report unauthorised entry at an early stage. Equally essential are fire alarm systems, whose planning and installation must follow the strict requirements of DIN 14675 and DIN VDE 0833-2, and where applicable VdS 2095, to protect people and assets from fire hazards.

In addition, video surveillance systems are deployed, serving the visual monitoring of interior and exterior areas and contributing to securing evidence in the event of an incident. Access control systems regulate access to sensitive areas and ensure that only authorised personnel can enter certain zones. These systems must be intelligently networked with one another to enable holistic hazard management. Planning this complex installation technology requires not only technical know-how but also a deep understanding of the object-specific risks and applicable standards. PLANATEL® plans these systems on a manufacturer-independent basis and optimises them for maximum efficiency and security.

IT Security as an Indispensable Pillar of the Security Concept

In the digital age, IT security is of the utmost relevance for banks. The BioCatch study "2025 Digital Banking Fraud Trends in Germany" shows that almost 70% of fraud losses in Germany arise via digital channels, and that Germany recorded the second-highest number of phishing attacks worldwide. A robust IT security concept must therefore encompass a broad spectrum of measures. This begins with comprehensive information risk management, which identifies and assesses risks and defines suitable countermeasures. An information security management system (ISMS) based on BSI IT-Grundschutz or ISO 27001 forms the organisational framework for continuously improving information security.

Technical measures include securing networks, servers and endpoints through firewalls, intrusion detection/prevention systems and antivirus software. User authorisation management is particularly critical, ensuring that employees can only access the data and systems necessary for their tasks. Regular penetration testing and vulnerability analyses are essential for proactively identifying security gaps. Effective incident response management is also crucial for reacting to cyberattacks quickly and in a coordinated manner. PLANATEL® advises banks on designing these complex IT security architectures, to ensure a high level of cyber resilience.

Organisational Measures and Personnel Management

In addition to technical systems, organisational measures and personnel management are decisive pillars of an effective security concept. Even the best technologies are ineffective if human error or a lack of awareness creates vulnerabilities. Clear security policies and procedures must therefore be established, covering all relevant processes, from data processing to physical access. These policies must be communicated and trained on a regular basis to embed a high level of security awareness among all employees.

Regular training and awareness campaigns are essential, particularly with regard to phishing attacks, which according to the TÜV Cybersecurity Study 2025 are responsible for 84 percent of successful cyberattacks. In addition, employee screening measures, such as background checks, are important for positions with access to sensitive information or systems. An established crisis management and contingency concept ensures that the bank remains able to act and that damage is minimised in the event of a security incident. This also includes defining clear responsibilities and communication channels. PLANATEL® supports the development of these organisational frameworks and their integration into existing corporate structures.

The Iterative Process of Concept Development and Implementation

Developing a security concept is a structured, iterative process that goes far beyond producing a one-off document. It begins with a detailed security and threat and risk analysis that identifies and assesses all internal and external risks. This covers both technical vulnerabilities and organisational shortcomings, as well as potential threats from crime or natural disasters. Based on this analysis, the protection objectives and security requirements are precisely defined, which must be oriented towards the business processes and regulatory requirements.

This is followed by the conception and detailed planning of the necessary measures and installation systems. A manufacturer-independent approach is crucial here, to find the optimal solution without dependence on a manufacturer. Planning is followed by tendering and awarding the contract to qualified installation companies, with PLANATEL® providing technical support and quality assurance. Implementation support and the subsequent acceptance of the systems ensure that the planned measures have been correctly implemented and that the protection objectives are achieved. This process requires continuous communication and experienced project management to guarantee the success of the security concept.

Our focus is always on optimising costs and processes, reducing risks and ensuring legal compliance. We plan maintenance concepts and select certified installers to guarantee the long-term functionality and reliability of the systems.

Continuous Review, Adjustment and Audits

A security concept is not a static document but a living system that requires continuous review and adjustment. The threat landscape is constantly evolving, new technologies emerge, and regulatory requirements change. It is therefore essential to regularly evaluate and update the security concept. This includes periodic risk assessments to identify new threats and re-evaluate existing risks. Technical audits of installed systems and IT infrastructure are also necessary, to ensure their functionality and currency.

DIN VDE 0833-1, which sets out general provisions for hazard alarm systems, emphasises the need for regular inspections of hazard alarm systems, at least four times a year, to ensure their proper condition and to take into account changes in the monitored area. External audits by independent experts provide an objective assessment of the effectiveness of the security concept and identify potential vulnerabilities. PLANATEL® supports banks in establishing these review mechanisms and adapting the concept to new circumstances, to ensure a consistently high level of security and secure legal compliance in the long term.

What is meant by a holistic security concept in the banking sector?

A holistic security concept in the banking sector integrates all relevant levels of protection: physical security (e.g. fire alarm systems, intrusion detection systems, access control), IT security (e.g. information risk management, ISMS, cyber defence) and organisational measures (e.g. policies, training, contingency planning). It considers the interactions between these areas and creates a coherent protection strategy that addresses both internal and external threats and ensures compliance with all relevant legal and supervisory requirements.

What role do MaRisk and BAIT play in a bank's security concept?

MaRisk (Minimum Requirements for Risk Management) and BAIT (Supervisory Requirements for IT in Financial Institutions) are central BaFin circulars that set out the framework for risk management and IT security in banks. They define organisational obligations and specific requirements for IT strategy, information risk management and IT operations, in order to ensure the stability and security of the financial sector and secure legal compliance.

How does a security concept protect a bank against cyberattacks?

A security concept protects against cyberattacks through a multi-layered approach. It encompasses information risk management, an ISMS (e.g. based on BSI IT-Grundschutz), network and endpoint security, strict user authorisation management, and regular vulnerability analyses and penetration tests. Effective incident response management is also crucial for reacting quickly to attacks.

What physical security measures are included in a bank security concept?

Physical security measures in a bank security concept include fire alarm systems to DIN 14675 and DIN VDE 0833-2, intrusion detection systems to DIN VDE 0833-3, video surveillance systems and access control systems. These installation systems serve the detection, alerting and control of access to sensitive areas, in order to protect people and assets.

Why is manufacturer independence important when planning security concepts?

Independent planners such as PLANATEL® can objectively select the best technologies and systems that precisely match the bank's requirements, without being influenced by sales interests or commissions. This leads to more cost-efficient, future-proof solutions.
