Frequently asked questions
What affects the security of www.hsgg.ucdavis.edu?
A valid SSL certificate still does not prove that www.hsgg.ucdavis.edu is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
Does www.hsgg.ucdavis.edu use HTTPS, and is its SSL certificate valid?
www.hsgg.ucdavis.edu used a valid SSL certificate at assessment time, valid until December 4, 2026. This status may change when the certificate expires or the server configuration changes.
Data compiled from CyStack cybersecurity monitoring systems
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
These 3 failed checks or warnings have the greatest impact on the result for www.hsgg.ucdavis.edu.
Allowed browser content (CSP)The inspected root HTML response does not include a Content-Security-Policy header.High
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.
Scope of this check
This check only evaluates the homepage response and content that the scanner could reach. Other pages and sign-in flows may use different settings.
DMARC blocking policyThe effective DMARC policy is quarantine and applies to 100% of messages.High
Why it matters
A policy of quarantine or reject tells receiving services to move suspicious mail to spam or refuse it. A monitoring-only policy (p=none) records the problem but does not ask receivers to stop spoofed mail.
What to do
After every legitimate sender passes DMARC, move gradually to quarantine and then reject, covering 100% of messages.
Protection from deceptive framing (clickjacking)The inspected root HTML response has no effective CSP frame-ancestors or X-Frame-Options restriction.Medium
Why it matters
Another website can place this page inside a hidden or misleading frame and trick a user into clicking an unintended action. Frame restrictions tell browsers which sites, if any, may embed the page.
What to do
Set frame-ancestors in CSP to the required trusted sites, and keep X-Frame-Options for older browsers when appropriate.

Which public IPs, services, and ports does www.hsgg.ucdavis.edu expose?
The assessment observed 1 public IPs and 2 open ports for www.hsgg.ucdavis.edu. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
How many subdomains of ucdavis.edu have been discovered?
