How Qualys WAS works and Architecture?

Architecture:
Qualys WAS is a cloud-based solution, meaning it operates and stores data in the cloud. The core components of Qualys WAS architecture include:

1. Qualys Cloud Platform: The Qualys Cloud Platform serves as the central hub for Qualys services, including Qualys WAS. It manages the scanning process, stores scan data, and provides a web-based interface for users to configure and manage scans.
2. Scanning Engines: Qualys WAS uses multiple scanning engines distributed across the cloud infrastructure to perform scans on web applications. These engines are responsible for sending requests to the target applications, analyzing responses, and identifying vulnerabilities.
3. User Interface: Qualys WAS offers a user-friendly web-based interface that allows users to configure scans, view scan results, and generate reports. Users can access this interface from anywhere with an internet connection.

Workflow:
The workflow of Qualys WAS typically involves the following steps:

1. Configuration: Users configure the scanning policies, targets (web applications or APIs), and authentication settings within the Qualys WAS web interface.
2. Scanning: Qualys WAS initiates scans by distributing tasks to its scanning engines. These engines crawl the target applications, send test payloads, and analyze responses to identify vulnerabilities.
3. Vulnerability Identification: The scanning engines identify vulnerabilities and generate detailed reports, including information about the type, severity, and location of vulnerabilities.
4. Reporting: Users can access the scan reports through the web interface. These reports provide insights into identified vulnerabilities and recommended remediation steps.
5. Remediation: Organizations can use the scan results to prioritize and remediate vulnerabilities in their web applications and APIs.

Qualys WAS’s cloud-based architecture offers scalability, ease of management, and the ability to perform continuous monitoring of web application security. It allows organizations to efficiently assess and improve the security of their web assets, ensuring the protection of sensitive data and compliance with security standards.
