In the dynamic and often treacherous landscape of web security, vigilance is paramount.
For industries that handle sensitive user data and facilitate critical transactions online – like the bustling hotel sector within the travel industry – a robust security posture isn’t just a recommendation; it’s a fundamental requirement for trust, compliance, and business continuity.
Proactive identification and remediation of vulnerabilities are key, and that’s where automated web security scanning tools come into play.
This blog post delves into the technical journey of building a web security scan portal using the cutting-edge Blazor framework for the frontend and seamlessly integrating the powerful IntruderAPI for initiating and managing security assessments.
We’ll explore the architectural considerations, the practical implementation using Blazor’s component-based approach, and illustrate its application with specific examples relevant to the hotel industry.
The Imperative of Web Security in the Hotel Industry
Hotels, by their very nature, are custodians of a wealth of personal and financial information. From booking details and credit card numbers to loyalty program data and guest preferences, the digital footprint of a hotel is a prime target for malicious actors.
A security breach can lead to devastating consequences: financial losses, reputational damage, legal liabilities, and a significant erosion of customer trust.
Consider the potential attack vectors in a typical hotel’s online ecosystem:
- Booking Engines: Vulnerabilities here could allow attackers to intercept payment information or manipulate booking details, leading to financial fraud and disrupted reservations.
- Property Management Systems (PMS) Integrations: Weaknesses in APIs connecting the booking engine to the PMS could expose sensitive guest data or allow unauthorized access to room inventory and pricing.
- Customer Portals: Flaws in guest login mechanisms or profile management features could enable account takeovers, granting access to personal information and potentially allowing unauthorized modifications to reservations.
- Third-Party Integrations: Hotels often integrate with various third-party services (e.g., review platforms, marketing automation tools), and vulnerabilities in these integrations can create backdoors into the hotel’s systems.
Therefore, a proactive and automated approach to web security scanning is crucial for hotels to continuously identify and address potential weaknesses before they can be exploited.
Choosing the Right Tools: Blazor for the Frontend and IntruderAPI for the Engine
Our solution leverages two powerful technologies:
- Blazor: Microsoft’s innovative framework for building interactive client-side web UIs with .NET. Blazor allows developers to write C# code that runs directly in the browser via WebAssembly, offering significant performance advantages and a familiar development experience for .NET teams. Its component-based architecture promotes modularity, reusability, and maintainability – essential for building a complex security portal.
- IntruderAPI: A robust and developer-friendly API provided by Intruder, a leading vulnerability scanner. IntruderAPI allows programmatic initiation of security scans, retrieval of scan results, and management of targets, providing the core engine for our security assessment portal. Its comprehensive scanning capabilities cover a wide range of web vulnerabilities, including OWASP Top 10, and its API-first design facilitates seamless integration into custom applications.
Architectural Overview: Building the Security Scan Portal
The architecture of our web security scan portal comprises the following key components:
- Blazor Frontend: The user interface built with Blazor components, providing users (security administrators, IT personnel) with the ability to:
- Define scan targets (URLs of hotel websites, booking engines, APIs).
- Configure scan settings (scan intensity, specific checks to include/exclude).
- Initiate security scans.
- View real-time scan status and progress.
- Browse detailed scan results, including identified vulnerabilities, severity levels, and remediation recommendations.
- Manage scan schedules and reports.
- Backend API (ASP.NET Core): A secure backend API built with ASP.NET Core acts as an intermediary between the Blazor frontend and the IntruderAPI. This layer handles:
- Authentication and authorization of users accessing the portal.
- Secure storage of IntruderAPI credentials (not exposed directly to the frontend).
- Orchestrating communication with the IntruderAPI (sending scan requests, retrieving results).
- Data processing and transformation (formatting IntruderAPI results for display in the Blazor frontend).
- Potentially storing scan history and reports in a local database.
- IntruderAPI: The external API provided by Intruder, responsible for performing the actual security scans based on the parameters provided by our backend API.
Blazor Frontend Implementation: Crafting the User Experience
Blazor’s component-based architecture shines when building the user interface for our security scan portal. We can create reusable components for various functionalities:
- Target Input Component: Allows users to enter the URLs of the hotel’s web assets to be scanned. For example, input fields for the main website (www.hotelname.com), the booking engine (book.hotelname.com), and specific API endpoints (api.hotelname.com/v1).
- Scan Configuration Component: Provides options for customizing the scan, such as selecting different scan profiles (e.g., quick scan, full scan), enabling or disabling specific vulnerability checks (e.g., SQL injection, cross-site scripting), and setting scan intensity.
- Scan Initiation Component: A button or form that triggers the initiation of a new security scan for the defined targets with the specified configuration. This component would communicate with our backend API.
- Scan Status Component: Displays the real-time status of ongoing scans, showing progress indicators and potentially logs or events streamed from the backend. Blazor’s SignalR integration could be leveraged for real-time updates.
- Scan Results Component: A key component that presents the detailed results returned by the IntruderAPI. This could involve:
- A table or list view of identified vulnerabilities, including their name, severity level (e.g., critical, high, medium, low), the affected URL, and a brief description.
- Expandable details for each vulnerability, including a comprehensive description of the issue, potential impact, and recommended remediation steps provided by Intruder.
- Filtering and sorting options to help users prioritize and analyze the findings.
- Reporting Component: Allows users to generate and download reports of scan results in various formats (e.g., PDF, CSV).

Backend API (ASP.NET Core) Integration with IntruderAPI:
The backend API acts as the crucial intermediary, securely interacting with the IntruderAPI. This involves:
- Configuration: Storing IntruderAPI credentials securely (e.g., using environment variables or Azure Key Vault).
- HTTP Client: Using HttpClient to make requests to the IntruderAPI endpoints.
- Scan Initiation Endpoint: An API endpoint (/api/scan) that receives scan target URLs and configurations from the Blazor frontend. This endpoint would then use the IntruderAPI client library or make direct HTTP requests to the IntruderAPI’s scan initiation endpoint.
- Scan Status Endpoint: An API endpoint (/api/scan/status) to retrieve the status of ongoing scans from the IntruderAPI.
- Scan Results Endpoint: An API endpoint (/api/scan/results) to fetch the detailed scan results from the IntruderAPI and format them for the Blazor frontend.
- Error Handling: Implementing robust error handling to manage potential issues during communication with the IntruderAPI.
