What to do first

  1. 1.

    Tell browsers to always use the secure version

    Helps browsers use HTTPS on future visits after they have received the policy.

    Who can fix it: Your web host

    How to verify after the fix

    curl -sIL https://berkeley.edu/ | grep -i "Strict-Transport-Security"
  2. 2.

    Limit what scripts your pages are allowed to run

    This adds one layer of protection against injected scripts.

    Who can fix it: Your website developer or web host

    How to verify after the fix

    curl -sIL https://berkeley.edu/ | grep -i "Content-Security-Policy"

A starting point, not a security guarantee.

DKIM — digital signature on email

Passed · Severity: OK · 5/5

A DKIM public key is published. On its own this doesn't prove outgoing mail is signed or aligned with your From domain.

DKIM public key found for selector: google, k1, s1, s2, mail. Confirm signing with dkim=pass in a sent message's Authentication-Results.

HTTPS available

Passed · Severity: OK · 10/10

The site loads over an encrypted connection.

https://berkeley.edu/ returned HTTP 200 (final URL: https://www.berkeley.edu/). Client-side certificate validation passed.

HTTP → HTTPS redirect

Failed · Severity: High · Hardening gap · 0/7

The site is also reachable over an unencrypted connection, so data may travel in plain text on public networks.

http://berkeley.edu/ returned HTTP 301 without redirecting to https:// (Location: http://www.berkeley.edu/).

Source data: HTTP GET http://berkeley.edu/ (redirects not followed)
HTTP 301
Location: http://www.berkeley.edu/
$ curl -sI http://berkeley.edu/ | grep -iE "^(HTTP|location)"
Fix recommendation (effort: Easy)
  1. Set up a permanent (301) redirect from every HTTP request to HTTPS on the server or CDN.
  2. Then add an HSTS header.
server {
  listen 80;
  server_name berkeley.edu www.berkeley.edu;
  return 301 https://$host$request_uri;
}

Safety: This change is made on your server. Make sure HTTPS works first, otherwise the site won't load.

SSL/TLS certificate validity

Passed · Severity: OK · 8/8

The certificate was accepted by a validating TLS client at scan time.

Live TLS handshake succeeded. Latest issuance in CT logs: Google Trust Services, expiring 2027-01-09 (54 days). CT shows issued certificates, not necessarily the one served — confirm dates with the verify command.

HSTS — enforce encryption in the browser

Failed · Severity: High · Hardening gap · 0/8

Browsers aren't told to always use an encrypted connection, enabling interception attacks on public networks.

No Strict-Transport-Security header. Users are exposed to SSL stripping on the first request.

Source data: Response headers from https://www.berkeley.edu/
Strict-Transport-Security: (missing)
$ curl -sIL https://berkeley.edu/ | grep -i "Strict-Transport-Security"
Fix recommendation (effort: Easy)
  1. Start with a short max-age (300 seconds) and make sure every subdomain works over HTTPS.
  2. Gradually raise it to 31536000 (one year) and add includeSubDomains.
  3. Consider preload only once the policy is stable — removal from the preload list is slow.
/*
  Strict-Transport-Security: max-age=31536000; includeSubDomains

Safety: This change is made in your server/CDN settings. Test on staging before production. HSTS is cached in the visitor's browser — a long max-age on a site without working HTTPS will block access.

Documentation: MDN — Strict-Transport-Security (https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Strict-Transport-Security) · RFC 6797 — HSTS (https://www.rfc-editor.org/rfc/rfc6797) · OWASP — HTTP Headers Cheat Sheet (https://cheatsheetseries.owasp.org/cheatsheets/HTTP_Headers_Cheat_Sheet.html)

CSP — protection from script injection

Failed · Severity: Medium · Hardening gap · 0/8

Missing Content-Security-Policy header: this removes one layer of protection against script injection.

No Content-Security-Policy header found.

Source data: Response headers from https://www.berkeley.edu/
Content-Security-Policy: (missing)
$ curl -sIL https://berkeley.edu/ | grep -i "Content-Security-Policy"
Fix recommendation (effort: Complex)
  1. First publish Content-Security-Policy-Report-Only — it blocks nothing, it only reports.
  2. Collect violations for a week or two and tune the policy to your legitimate sources.
  3. Switch to the Content-Security-Policy header and replace 'unsafe-inline' with a nonce or hash.
/*
  Content-Security-Policy-Report-Only: default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'

Safety: This change is made in your server/CDN settings. Test on staging before production. An overly strict CSP will break scripts — that's why you start in Report-Only mode.

X-Content-Type-Options

Failed · Severity: Low · Hardening gap · 0/4

The browser may interpret files as code unintentionally.

Missing X-Content-Type-Options: nosniff header (MIME sniffing).

Source data: Response headers from https://www.berkeley.edu/
X-Content-Type-Options: (missing)
$ curl -sIL https://berkeley.edu/ | grep -i "X-Content-Type-Options"
Fix recommendation (effort: Easy)
  1. Add X-Content-Type-Options: nosniff to every response.
/*
  X-Content-Type-Options: nosniff

Safety: This change is made in your server/CDN settings. Test on staging before production.

Permissions-Policy

Needs attention · Severity: Low · Hardening gap · 0/2

Access to sensitive features like the camera and location isn't restricted.

Missing Permissions-Policy header.

Source data: Response headers from https://www.berkeley.edu/
Permissions-Policy: (missing)
$ curl -sIL https://berkeley.edu/ | grep -i "Permissions-Policy"
Fix recommendation (effort: Easy)
  1. Disable browser features the site doesn't need (camera, microphone, geolocation).
/*
  Permissions-Policy: camera=(), microphone=(), geolocation=()

Safety: This change is made in your server/CDN settings. Test on staging before production. Don't disable a feature the site actually uses.

Software version disclosure

The server doesn't disclose software versions.

No version numbers found in the Server / X-Powered-By headers.

DNSSEC — signed DNS records

Passed · Severity: OK · 7/7

The domain's records are digitally signed and hard to forge.

An AD (Authenticated Data) flag was returned by a validating resolver.

Source data: DNS-over-HTTPS (Cloudflare / Google): AD flag and DS record at the parent

CAA — who may issue certificates

Needs attention · Severity: Low · Hardening gap · 0/5

Any certificate authority can issue a certificate for the domain, raising the risk of mis-issuance.

No CAA records found. RFC 8659 lets the domain owner restrict which CAs are authorized.

Source data: DNS CAA berkeley.edu
(no CAA records found)
$ dig +short CAA berkeley.edu
Fix recommendation (effort: Easy)
  1. Identify which certificate authority issued your current certificate (see the certificate check).
  2. Publish CAA for that authority only, and add iodef to receive alerts.
berkeley.edu.  CAA  0 issue "letsencrypt.org"
berkeley.edu.  CAA  0 iodef "mailto:security@berkeley.edu"

Safety: DNS changes are made only at your DNS provider. This tool only reads public data and changes nothing on the domain. If your CDN issues certificates on your behalf, include it too — otherwise certificate renewal will fail.

Documentation: RFC 8659 — CAA (https://www.rfc-editor.org/rfc/rfc8659)

DNS server redundancy

Passed · Severity: OK · 3/3

The domain is served by several DNS servers, so one server failing won't take it down.

3 NS servers.

Source data: DNS NS berkeley.edu
adns1.berkeley.edu

Indicative alignment

Best-practice mapping of public findings to common frameworks. Passive scanning tests public configuration only; it doesn't prove compliance or a violation.

  • Google & Yahoo sender rulesNo gaps observed
  • PCI DSS v4.03 observed gaps
  • NIS2 / vendor due diligence2 observed gaps
  • SOC 2 / ISO 27001 baseline3 observed gaps

Indicative alignment only, based on public configuration. It doesn't establish whether a framework applies to you, and it isn't legal advice, an audit or a certification.
