“Virtual Patching” is a term not only web-application specific but mainly used by WAF providers over the past years. It is also referred as External Patching or Just-in-time Patching. It is a technique of fixing a retardant by fixing or eliminating a vulnerability by dominant either the inputs to its application through an external application, shim, proxy, or virtual server.
A quick repair job for a piece of software code is called a patch. The virtual patch works once the security enforcement layer analyses transactions and intercepts attacks in transit, therefore the malicious traffic never gets to the web application. The impact of virtual patching is that without updating the source code, it prevents an exploit from occurring.
Safeguarding the company’s assets against existing and emerging vulnerabilities is the most critical task that security teams are struggling with. Various tools are used to achieve Deep Security virtual patching. The WAF provides the most sustainable solution for virtual patching. WAF works well in securing your websites and applications.
Prophaze automatically deploys virtual patching to web applications, APIs and microservices to block malicious traffic from exploiting vulnerabilities, before the application source code can be modified. Considering the many situations when organizations can’t immediately modify the source code, makes the value of virtual patching significant.
- Patching is scalable and implemented on all hosts
- Does not conflict with libraries and support code file
- Eliminates time and money spent on emergency patching
- Protects mission-critical systems that cannot be taken offline
- Reduces risk until a vendor-supplied patch is released and tested
- Enables agile CI/CD teams to remediate vulnerabilities and release code without stopping productions.
Patch Management is a strategic process of acquiring, testing, and installing updated software. But, most of the companies find themselves comply less than strictly with their patching schedule. Customers can reduce risk while lengthening their patching cycles, helping their overtaxed IT departments, and reducing patching costs by simply applying this patch management strategy.
Virtual patching demands applying a layer of security policy that prevents and intercepts vulnerability exploitation. A productive solution requires the capabilities to analyze and block malicious activity from web-traffic, identify & prevent intrusions, prevent web application attacks, and flexible deploy on the cloud, or physical environments. Deep security virtual patching includes the option to secure the web-apps without patching them. These solutions are much faster and they don’t need any application language programming. It controls the patch cycle without compromising security.
