Challenge

Cyberattacks have emerged as one of the most significant threats to the security of business systems in financial institutions. Distributed Denial-of-Service (DDoS) attacks, malware infections, and ransomware incidents targeting the financial sector have become increasingly prevalent. As a result, ensuring the security of online business systems has become a critical concern for these institutions. National governments and financial regulatory authorities place significant emphasis on cybersecurity and have enacted laws and regulations such as the Cybersecurity Law, the Multi-Level Protection Scheme (MLPS), and the Critical Information Infrastructure (CII) Security Regulations to estrengthen cybersecurity and protect critical infrastructure. As a result, developing the ability to detect, defend against, and trace cyberattacks has become a top priority in the cybersecurity strategies of financial institutions.

Background

The financial industry operates numerous business systems. These include online banking platforms, transaction and settlement systems, and call center systems in the banking sector; product management, policy administration, and claims processing systems in the insurance sector; and securities registration, trading, and information service systems in the securities sector. These systems support both internal and external services.

Given their critical role in daily operations and exposure to potential threats, the assurance of system availability, confidentiality, and integrity is imperative for both cybersecurity compliance and business operation.

Specifically, it is essential to defend against a wide range of cyber threat activities, including reconnaissance and information gathering, scanning and vulnerability discovery, exploitation and privilege escalation, persistence and backdoor implantation, as well as website defacement and malware injection. At the same time, the financial industry must be prepared to counter threats originating from malware, hackers, organized cybercrime groups, and hostile actors.

Solution Overview

By deploying WebRAY's RayWAF Web Application Firewall and RayLock Web Page Tamper-Proofing System, a comprehensive in-depth defense architecture can be established for application systems. The application firewall cluster is deployed in front of business systems within the internet server zone, enabling high-throughput, high-concurrency, and high-availability protection. This intercepts attacks before they reach the application systems, achieving proactive defense. The web page tamper-proofing client is deployed on internet-facing business systems to ensure that web pages remain intact and free from malicious code injection, providing real-time protection. Upon detection of tampering, the system can automatically restore the original content, supporting rapid post-incident recovery. The web page tamper-proofing client is also installed on office business systems to enable real-time (inline) defense and support post-incident recovery and emergency response capabilities.

Advantages

In-Depth Defense

A two-layered security architecture is implemented by deploying Web Application Firewalls at the front end and tamper-proofing clients on the application servers.

Full-Lifecycle Defense

The Web Application Firewall provides pre-incident protection by blocking attacks before they reach the application. The web page tamper-proofing system prevents in-incident damage by detecting and stopping unauthorized modifications in real time. It also enables post-incident recovery by restoring compromised pages. Additionally, the WAF’s honeypot function supports attack tracing.

Protocol Compliance Inspection

Performs protocol-level validation on HTTP packet parameters to to prevent the transmission of unauthorized data packets.

Web attack protection

Utilizes a built-in threat signature database to detect and block common web attacks, including those listed in the OWASP Top 10.

Application Value

Environment Flexibility

Supports multiple deployment modes including transparent mode, transparent proxy mode, reverse proxy mode, bypass monitoring mode, and bypass blocking mode, enabling adaptation to diverse financial network environments.

Comprehensive Protection

Implements an integrated defense solution combining WAF, honeypot, web page tamper-proofing, and web page recovery to meet the full security lifecycle requirements of pre-attack prevention, real-time response, and post-attack recovery and attack tracing.

Simple Maintenance Process

Through site auto-learning and intelligent semantic analysis, deployment and maintenance can be achieved rapidly and simply. There is a comprehensive protection across the entire attack lifecycle, including prevention, alerting, recovery, and evidence collection, which can significantly improve the efficiency of security management.
