AI-suggested
- Monitor Priority vendor communications closely and apply security patches immediately once released for versions 23.0 and below.
- Implement strict input validation and output encoding on all user-supplied data within Priority Web applications to prevent script injection.
- Enforce the principle of least privilege by limiting user roles and permissions, especially for web application users with elevated rights.
- Educate users about the risks of interacting with suspicious links or content within the Priority Web environment to reduce the likelihood of triggering malicious scripts.
- Employ web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting Priority Web.
- Conduct regular security assessments and code reviews focusing on input handling and sanitization in Priority Web customizations.
- Enable Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the web application context.
- Monitor logs and network traffic for unusual activity that could indicate exploitation attempts.
