1 - DDoS Protection Preparation

Configure firewall open settings

Client (User) - SECaaS (DDoS Protection) - Origin Server Each segment requires firewall opening. For the information required to open the firewall (Source, Type, Protocol, Destination), please inquire via the Support Center > Contact Us menu.

Reference
Samsung SDS network users do not need to submit a separate firewall opening request.
  1. Proceed with opening the firewall for the segment where the client (User) connects to SECaaS (DDoS Protection).
    • The default supported web ports for SECaaS are as follows.
      • http : 80, 8080, 8880, 2052, 2082, 2086, 2095
      • https : 443, 2053, 2087, 2096, 8443
    • For websites that use ports other than the default supported web ports, fill out the DDoS Protection service request form to submit a service request. We will provide the Destination IP via the email account on the service request form. If the ports are changed (added, removed) or the Origin is changed after applying SECaaS, the IP may change. If you email the security monitoring center account (securitucenter@samsung.com) in advance, we will inform you of the changed IP through the responsible person.
      • If you are not using an IPv6 address, registration is not required.
      • The service application form can be downloaded and attached from the All Services > Security > DDoS Protection menu by clicking the DDoS Protection Service Request button, then downloading it on the Service Request screen.
      • For information related to service application, see the How-to guides’ DDoS Protection 생성하기.
        SourceTypeProtocolDestination: SECaaS
        ClientHTTP, HTTPSTCP
        • IPv4: 162.159.141.5 / 172.66.1.3
        • IPv6: 2606:4700:7::102 / 2a06:98c1:58::102
        Table. Example of IP forwarding form
  2. Proceed with opening the firewall for the segment that connects to the Origin Server in SECaaS(DDoS Protection).
    • The origin server is the device that receives traffic from SECaaS. (e.g., LB, server, etc.)
    • The firewall or security device in front of the origin server must allow a specific range.
      • Cloudflare IP range information: https://www.cloudflare.com/ko-kr/ips/
      • If you are not using an IPv6 address, registration is not required.
        Caution
        We recommend blocking web traffic (HTTP, HTTPS) outside the specified range. If not blocked, the Origin IP may be exposed, potentially enabling attacks that bypass SECaaS, and such bypass attacks are difficult to monitor for security.

Authenticate SECaaS domain

To authenticate the registrant of the domain, you must create a host and add a TXT record for domain verification to DNS.

  • Authentication typically takes about 15 minutes after registration, but can take up to 24 hours depending on the environment. For example, when registering www.test.com, you must create/enter the Host and TXT Record values we provide into DNS.

Applying SECaaS Certificate

You can select and use either the certificate provided by SECaaS or the certificate supplied by the customer. Certificate installation is possible only if HTTPS is enabled for the domain; if the certificate is not installed, HTTPS communication will not work.

1. When using SECaaS certificate

  • A new SSL certificate used between the Client ↔ SECaaS server will be generated.
  • Validation of the domain owner is required for the generated SSL certificate. The owner verification is performed by creating/entering the HOST and CNAME values we provide into DNS.
  • Certificates cannot be extracted and delivered, and there is an automatic renewal feature, so no separate renewal is required.
  • Authentication typically takes about 15 minutes after registration, but may take up to 24 hours depending on the environment.

2. When using a client (Custom) certificate

  • Provide the Full chain certificate, Key File, and Key Value.
  • An API communication issue occurs when registering a single certificate. (Only pfx, pem, cer files are supported)
  • The renewed certificate must be provided for renewal before the certificate expires.

2 - DDoS Protection Service Application

After completing the service request on the service request page, proceed with the steps below in order.

Perform pre-test

  1. Before changing the traffic path with SECaaS, run a test to verify that it works correctly.
    • The security monitoring center provides the IP to be used in SECaaS. Example: 103.22.200.1
    • We will explain using aaa.test.com as the website example.
    • Add the example text below to the C:\Windows\System32\drivers\etc\hosts file and save it.
      • Example phrase : 103.22.200.1 aaa.test.com
  2. When accessing a URL in Chrome, press F12 and then select F5 (Refresh) in the Network tab at the top of the developer tools.
  3. The process completes when the response header ‘X-cdn’ has the imperva value, or when a SECaaS IP is present in the remote address.

Changing DNS Settings

The path is changed so that actual traffic is transmitted via SECaaS.

  • We will configure each domain’s address as a CNAME using the provided CNAME domain. When using a CDN, change the CDN’s origin address to a CNAME.
  • Root (Naked) domains cannot have a CNAME record. It is recommended to configure an A record using the two default Anycast IPs. If setting both IPs is difficult, configure only one.
    • Example: Register or modify DNS for test.com using the CNAME we provide, and register or modify an A Record DNS for test.com using the IP we provide.

Notify DNS Change

After the DNS change is announced, the security monitoring center checks for proper integration and traffic inflow.

Caution
If the DNS change is not reported, we cannot determine whether it will be applied. Be sure to notify the service manager before changing DNS settings or after the change is completed.

Check Service

Verify normal service connectivity.

  • Check whether an SSL certificate error occurs.
  • DDoS Protection is operated in detection mode for one month, after which the logs are analyzed and provided to the service owner.
    • If no legitimate traffic is detected as an attack, switch to block mode. If a false positive occurs, verify with the service owner and then add an exception in DDoS Protection.

3 - DDoS Protection Service Outage Response

When a DDoS Protection service outage occurs, follow the steps below to address and respond to the issue.

Service outage detection

  • The service owner will become aware of a failed service URL health check or a response error.
  • The security monitoring center will encounter SECaaS service disruptions and cause the registered Origin Healthcheck to fail.

Remediation

  • After identifying the cause of the failure, if it is determined to be a SECaaS service outage, you must change the registered CNAME/A Record values to the original service’s Origin IP/address for redirection (reversion) and apply them. Since DNS values need to be changed, the user must handle it directly.
  • When an urgent bypass (restoration) is required.
    • SECaaS(DDoS Protection) → Server(Origin) Open the segment firewall to any.
    • You can achieve the same effect by asking the SECaaS administrator to request DNS bypass processing in the SECaaS settings. (It is applied based on the DNS TTL value and takes about five minutes.)
    • Websites that have DNS applied via an A Record value, such as a root (naked) domain, cannot be used.

SECaaS reapplication

After the outage is resolved, reapply the modified CNAME/A Record values to the SECaaS CNAME/A Record address.
