In cybersecurity, an HTTP gateway is a system that acts as an intermediary between a client (like a web browser) and a web server. It handles incoming HTTP requests from clients and forwards them to the appropriate server, then returns the server's response to the client. While seemingly simple, this function has significant security implications.

Here's why HTTP gateways are essential for cybersecurity:

• Security Filtering: They can act as a first defense against web-based threats. Gateways can be configured to block access to known malicious websites, filter out harmful content like malware downloads, and prevent data leakage by inspecting outgoing traffic.

• Access Control: HTTP gateways can enforce access control policies, ensuring that only authorized users can access specific web resources. This can be based on user authentication, IP addresses, or other criteria.

• Web Application Firewall (WAF): Many HTTP gateways include WAF functionality. A WAF explicitly protects web applications by filtering out malicious traffic and blocking attacks like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).

• Monitoring and Logging: Gateways can monitor web traffic, log events, and provide valuable insights into user activity and potential security incidents. This data can be used for threat analysis, incident response, and compliance reporting.

• Reverse Proxy: Acting as a reverse proxy, an HTTP gateway can protect web servers from direct exposure to the internet. This hides the server's internal IP address and can provide load balancing and caching to improve performance and availability.

Examples of HTTP gateways in action:

• Secure Web Gateways (SWGs): Organizations often deploy these to protect users from web-based threats and enforce acceptable use policies. They can be cloud-based or on-premises.

• Content Filtering Solutions: These gateways focus on blocking access to inappropriate or undesirable websites, often used in schools or businesses to restrict access to certain types of content.

• API Gateways: These specialized gateways manage and secure access to APIs (Application Programming Interfaces), ensuring only authorized applications and users can access specific API endpoints.

HTTP gateways are crucial in securing web traffic and protecting organizations from various web-based threats. By filtering traffic, enforcing access control, and providing other security functions, they help maintain a safe and secure online environment.

ThreatNG can effectively contribute to the security of HTTP gateways by:

1. Discovery and Assessment: ThreatNG can identify all HTTP gateways deployed within your organization's network, even those that may not be officially documented or managed. It then assesses their security configuration, checking for weak passwords, unpatched vulnerabilities, and misconfigurations that could expose the gateway and the internal systems it protects.

2. Reporting: ThreatNG provides detailed reports on the security posture of HTTP gateways, highlighting any identified vulnerabilities and their potential impact. These reports can be used to prioritize remediation efforts and track improvements over time.

3. Policy Management: ThreatNG allows you to define and enforce security policies for HTTP gateways, ensuring consistent configurations and adherence to industry best practices. This can include policies for password management, access control, and software updates.

4. Investigation Modules: ThreatNG's investigation modules, such as the Domain Intelligence module, can provide deeper insights into the HTTP gateway's technology stack, including the vendor, version, and known vulnerabilities. This information can be crucial for risk assessment and vulnerability management.

5. Intelligence Repositories: ThreatNG leverages various intelligence repositories, including vulnerability databases and threat intelligence feeds, to identify emerging threats and vulnerabilities relevant to HTTP gateways. This helps organizations stay ahead of attackers and proactively mitigate potential risks.

6. Detecting Externally Exposed Instances: ThreatNG can detect HTTP gateways that are inadvertently exposed to the internet, making them susceptible to attacks from external threat actors. This is particularly important for gateways that handle sensitive data or provide access to critical internal resources.

7. Working with Complementary Solutions: ThreatNG can integrate with other security solutions, such as web application firewalls (WAFs) and intrusion detection/prevention systems (IDPS), to provide comprehensive protection for HTTP gateways and their applications. For example, ThreatNG can share threat intelligence with the WAF to enhance its ability to block malicious traffic.

Examples of ThreatNG working with complementary solutions:

• ThreatNG + WAF: ThreatNG identifies a vulnerability in an HTTP gateway and provides this information to the WAF. The WAF then updates its rules to specifically protect against attacks that exploit this vulnerability.

• ThreatNG + IDPS: ThreatNG assesses the susceptibility of an HTTP gateway to known exploits and alerts the IDPS. The IDPS then adjusts its monitoring and blocking rules to focus on the potential attack vectors highlighted by ThreatNG, increasing the likelihood of detecting and preventing malicious activity targeting the gateway.

By combining ThreatNG's capabilities with complementary security solutions, organizations can establish a robust security framework for their HTTP gateways, ensuring the confidentiality, integrity, and availability of their web applications and sensitive data.
