Virtual Patching of Vulnerabilities at the Pace of Business

July 1, 2021

As the pace of digital change accelerates, you don’t want barriers in the way of your transformation strategy. Any delays need to be addressed at the speed of business to sustain a competitive advantage.

Fixing software bugs with code changes or system patches remains a critical security task that needs to be conducted rapidly and reliably, even though it takes significant time. Moreover, many organisations also lack DevSecOps expertise. This is especially the case with legacy applications. For example, it can be disastrous when a legacy application uses a web interface, a popular database back-end or a component whose source code is unavailable or difficult to modify.

It can take days, weeks, or months to find the root cause of the problem, issue a fix, test it, and launch it into production. During this time, sensitive data is exposed to potential attacks without protection.

Your goal must be the integration of frictionless security. Imagine instead a scenario whereby you can issue a fix in hours. The threat to your web application is closed almost immediately, so that development and infrastructure teams have enough time to fix vulnerabilities properly.

This is virtual patching in action.

Virtual patching is achieved by a dedicated rule or a set of rules deployed in a web application firewall (WAF) that diminishes a software vulnerability without changing the underlying codebase. A WAF filters, monitors, and blocks HTTP traffic to and from the web service. By inspecting traffic, it can prevent attacks exploiting a web application’s known vulnerabilities. Virtual patching is ideal when an urgent fix is required: this type of remediation implements a security policy enforcement layer, enabling your operations team to keep a system running until a complete fix passes design, development, testing, and approval.

Virtual Patching Partnership

Here at YesWeHack, we partnered with Rohde & Schwarz cybersecurity to deliver agile and effective virtual patching. Seamless integration between the Rohde & Schwarz WAF and the YesWeHack platform enables you to discover and protect against high-impact vulnerabilities quickly and efficiently, dramatically reducing your risk exposure. Where in the past it may have taken you days, weeks, or even months to remediate a vulnerability – now you can do it in hours.

The highly scalable solution can be deployed on-premises, in public clouds and hybrid / multi-cloud environments.

So how does it work?

Once a YesWeHack ethical hacker identifies a vulnerability, the report is evaluated, and you can request and receive a virtual patch at the click of a button. The process couldn’t be simpler:

1️⃣ You request a patch for the vulnerability directly from your vulnerability report interface, adding information and insight as necessary.

2️⃣ The request is acknowledged and examined. You can review the status of the virtual patch throughout the process.

3️⃣ When a fix is available, the bug bounty program manager integrates it and provides it for testing to the hunter who identified the initial vulnerability.

4️⃣ The hunter confirms the bug cannot be reproduced or bypassed. If it passes the test, you can immediately push forward with the DevSecOps pipeline.

5️⃣ Whatever the type of patch you deploy, all actions are logged. That sort of changelog is precious in highly compliant environments. No more tedious Excel sheets!

This innovative YesWeHack and Rohde & Schwarz cybersecurity integration enable rapid, virtual patching of application vulnerabilities. The WAF rapidly blocks the exploitation of a vulnerability, reducing the time-sensitive data is exposed to potential attacks to hours, not days.

It makes sense on every level. You receive a patch in a fraction of the time and cost of traditional methodologies. Patch requests, tests, and acceptance are tracked as they happen. You have complete visibility throughout the process. And, of course, your application portfolio remains secure and free of vulnerabilities.
