What is Virtual Patching?
Virtual patching, also known as digital patching, is a crucial technique used in the realm of application security within the broader context of information security and cybersecurity. It involves creating a protective barrier that mimics the functionality of a traditional security patch without actually altering the source code of the application.
Key Characteristics
- Immediate Protection: Virtual patching provides an immediate defense against known vulnerabilities, allowing organizations to safeguard their applications before official patches are available.
- Layered Security: It acts as an additional layer of security, complementing existing security measures and helping to mitigate risks associated with unpatched vulnerabilities.
- Reduced Downtime: By avoiding disruptive patching processes, virtual patching minimizes downtime and ensures business continuity.
How It Works
The virtual patching process involves the use of web application firewalls (WAF) or intrusion prevention systems (IPS) that filter and monitor HTTP traffic. These security solutions can detect and block exploit attempts targeting known vulnerabilities, effectively providing a temporary fix until the appropriate patch is applied.
Conclusion
In summary, virtual patching serves as a vital strategy for organizations to manage security risks associated with vulnerabilities in software applications while maintaining operational efficiency and security integrity.
