Frequently asked questions
What affects the security of quangngai.edu.vn?
A valid SSL certificate still does not prove that quangngai.edu.vn 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 quangngai.edu.vn use HTTPS, and is its SSL certificate valid?
quangngai.edu.vn used a valid SSL certificate at assessment time, valid until October 11, 2026. This status may change when the certificate expires or the server configuration changes.
Have @quangngai.edu.vn email addresses appeared in exposed data or information-stealer (infostealer) logs?
Data sources
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 quangngai.edu.vn.
Unencrypted legacy serviceA confirmed public legacy cleartext service was found: 103.68.251.133:21 (ftp).High
Why it matters
Older services such as Telnet, FTP, and unencrypted mail or directory protocols can send passwords and data in readable form. Anyone able to observe the network path may capture them.
What to do
Disable the legacy service or replace it with an encrypted alternative such as SSH, SFTP, HTTPS, or the secure version of the mail protocol.

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.
Email spoofing protection (DMARC)No DMARC record was found for the registrable email domain.High
Why it matters
DMARC lets the domain owner tell receiving services what to do when the visible From address is not verified by SPF or DKIM. Without DMARC, attackers have more opportunity to impersonate the domain in phishing email.
What to do
Publish a DMARC record at _dmarc, begin by collecting reports, and confirm that legitimate senders pass before applying a blocking policy.
