Zotgpt Domain Security

method: probed
provider: ZotGPT (UC Irvine)
providerId: zotgpt
description: >-
  Live TLS, transport, DNS, and identity-plane probe of the ZotGPT hosts. The
  probe is the clearest single piece of evidence for the platform's multi-cloud
  posture: every interactive product terminates on a UC Irvine-owned AWS
  Application Load Balancer in us-west-2 under the *.aws.uci.edu naming
  convention, with an Amazon-issued certificate, while the developer API control
  plane terminates on Azure API Management in the same region. Two clouds, one
  campus namespace.

    notes: >-
      Marketing and documentation site. Certificate CN is the AWS account's
      internal LB name, which is why the campus AWS account naming
      (zot-gpt-prod) is externally visible.

    notes: >-
      Redirects unauthenticated callers into the campus Shibboleth IdP. Sets
      secure, HttpOnly, SameSite=None OpenSAML session cookies.

    notes: >-
      Separate ALB and separate environment from Chat — the "modular
      architecture ... isolates each instance with separate policies" that UCI
      describes for classroom versus private use is visible in DNS.

    title: 'UC Irvine API Management'
    notes: >-
      Azure API Management developer portal, West US 2, fronted by Azure Traffic
      Manager. The APIM gateway itself (oit-apim-usw2.azure-api.net) answers with
      an APIM JSON envelope. This is the developer control plane for the
      deprecated API.
  - host: api.zotgpt.uci.edu
    status: 0
    resolves: false
    notes: >-
      Documented data-plane host for the deprecated API. NXDOMAIN from the public
      internet — campus-internal or already withdrawn.
  - host: api.azureapi.zotgpt.uci.edu
    status: 0
    resolves: false
    notes: Old base URL quoted in the migration guide. NXDOMAIN publicly.
identity_plane:

  metadata: https://shib.service.uci.edu/idp/shibboleth
  metadata_status: 200
  metadata_content_type: application/xml
  protocol: SAML 2.0 (Shibboleth)
  notes: >-
    The IdP publishes its SAML metadata anonymously — the only machine-readable
    descriptor anywhere in the ZotGPT estate that a third party can retrieve
    without credentials.
email_domain_security:
  domain: uci.edu
  spf: 'v=spf1 include:%{ir}.%{v}.%{d}.spf.has.pphosted.com ?all'
  spf_notes: >-
    Proofpoint macro-expanded include with a soft ?all rather than -all.

  dnssec: not enabled (no DS record for uci.edu)
  caa: no CAA record published for uci.edu
findings:
  - severity: informational
    finding: >-
      Multi-cloud is real and externally verifiable — AWS us-west-2 for every
      application plane, Azure West US 2 for the API management plane.
  - severity: informational
    finding: >-
      Product isolation is real — Chat, ClassChat, and Creator each run in their
      own named AWS production environment behind their own load balancer.
  - severity: low
    finding: >-
      No security.txt at /.well-known/security.txt on any ZotGPT host (404).
  - severity: low
    finding: >-
      No robots.txt on zotgpt.uci.edu (404), and no sitemap.xml.
  - severity: low
    finding: >-
      uci.edu publishes no CAA record and no DS record (DNSSEC not enabled), and
      DMARC is at p=none.
  - severity: informational
    finding: >-
      Internal AWS account and environment names (zot-gpt-prod,
      oit-instructorbot-prod, oit-zotgptcreator-prod) are disclosed through
      certificate subjects and CNAME chains.
