## Vendor risk summary
This vendor risk report is based on UpGuard's continuous monitoring of BIG4 Holiday Parks of Australia's security posture using open-source, commercial, and proprietary threat intelligence feeds. The results are summarized into a security rating based on the analysis of hundreds of individual checks across five risk categories: website security, email security, phishing & malware, brand & reputation risk, and network security.

## Security categories

### Email

- Pass — DMARC policy is not p=none
  - DMARC reject policy provides the most effective protection against fraudulent emails being sent from a domain.
- Pass — DMARC policy exists
  - DMARC protects against fraudulent emails being sent from a domain.
- Pass — Strict SPF filtering - not using +all
  - Sender Policy Framework (SPF) record strictly enforces specific domains allowed to send email on its behalf.
- Pass — SPF syntax correct
  - Sender Policy Framework (SPF) record passes basic syntax checks.
- Pass — DMARC policy percentage is default
  - DMARC policy percentage is set to default 100%, ensuring all mail is covered by the policy.
- Pass — SPF ptr mechanism not used
  - Sender Policy Framework (SPF) record does not include the ptr mechanism.

### Network

- Pass — No ports are open
  - No open ports were detected.

### DNS

- Fail — DNSSEC not enabled
  - DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.
- Fail — CAA not enabled
  - The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.
- Pass — No unregistered MX records detected
  - No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected.

### Encryption

- Fail — HTTP Strict Transport Security (HSTS) not enforced
  - Without HSTS enforced, people browsing this site are more susceptible to man-in-the-middle attacks. The server should be configured to support HSTS.
- Fail — Insecure SSL/TLS versions available
  - Any version of the SSL protocol, and TLS prior to version 1.2, are now considered insecure. The server should disable support for these old protocols.
- Fail — Insecure cipher suite supported
  - Insecure cipher suites can be trivially broken by an attacker, allowing them to impersonate your server or eavesdrop on traffic.
- Fail — SSL expires in less than 20% of its total valid period
  - SSL certificate has less than 20% of its total valid period remaining. The certificate will need to be renewed to avoid expiry.
- Pass — Certificate not found on our revoked certificate list
  - The site's certificate chain was checked against our list of revoked certificates.
- Pass — SSL available
  - SSL is supported for this site.
- Pass — Hostname matches SSL certificate
  - The site's hostname matches the SSL certificate.
- Pass — SSL has not expired
  - SSL certificate has not expired.
- Pass — Trusted SSL certificate
  - The certificate presented by this domain was issued by a trusted certificate authority.
- Pass — SSL certificate chain present in server response
  - A complete SSL certificate chain was presented by the server for this domain.
- Pass — SSL chain certificates do not expire within 20 days
  - SSL intermediate and root certificates do not expire within 20 days.
- Pass — SSL expiration period shorter than 398 days
  - The SSL certificate presented by the server has an expiration period shorter than 398 days.
- Pass — Strong SSL algorithm
  - Industry standard SHA-256 encryption in use.
- Pass — Strong Diffie-Hellman prime used in key exchange
  - TLS connections to the site use a strong Diffie-Hellman prime during key exchange.
- Pass — Strong public certificate key length
  - The site's public certificate provides at least 112 bits of security strength.
- Pass — No weak cipher suites supported in TLS 1.2
  - TLS connections to the site do not support any weak cipher suites.
