If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can help to monitor network traffic and detect any malicious activities, thereby providing an additional layer of security until the patch can be installed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview In the field of cybersecurity, the discovery of new vulnerabilities is a common occurrence.
