The purpose of this policy is to establish requirements for ensuring third-party service providers/vendors meet Bangkok Solutions requirements for preserving and protecting Bangkok Solutions information.


The policy applies to all IT vendors and partners who have the ability to impact the confidentiality, integrity, and availability of Bangkok Solutions’s technology and sensitive information, or who are within the scope of Bangkok Solutions’s information security program. This policy also applies to all employees and contractors that are responsible for the management and oversight of IT vendors and partners of Bangkok Solutions.


This policy prescribes the minimum standards a vendor must meet from an information security standpoint, including security clauses, risk assessments, service level agreements, and incident management.

Roles and Responsibilities

The acting information security officer and team will facilitate and maintain this policy and ensure all employees have reviewed and read the policy.


Bangkok Solutions makes every effort to assure all 3rd party organizations are compliant and do not compromise the integrity, security, and privacy of Bangkok Solutions or its customer data. 3rd parties include customers, partners, subcontractors, and contracted developers.

  • IT vendors are prohibited from accessing Bangkok Solutions’s information security assets until a contract containing security controls is agreed to and signed by the appropriate parties.
  • All IT vendors must comply with the security policies defined and derived from Bangkok Solutions’s Information Security Program to include the Acceptable Use Policy.
  • IT vendors and partners must ensure that organizational records are protected, safeguarded, and disposed of securely. Bangkok Solutions strictly adheres to all applicable legal, regulatory and contractual requirements regarding the collection, processing, and transmission of sensitive data such as Personally-Identifiable Information (PII).
  • Bangkok Solutions may choose to audit IT vendors and partners to ensure compliance with applicable security policies, as well as legal, regulatory and contractual obligations.

Vendor Inventory

An inventory of third party service providers shall be maintained, and the inventory will include:

  • Vendor risk level
  • Types of data shared with the third party
  • Brief description of services
  • Main point of contact at the third party
  • How access is granted to the third party vendor
  • Significant controls in place
  • Security policy/report and/or questionnaire

Vendor risk level assessment will be based on the following considerations:

  • High: the vendor stores or has access to sensitive data and a failure of this vendor would have critical impact on your business
  • Moderate: the vendor does not store or have access to sensitive data and a failure of this vendor would not have critical impact on your business
  • Low: the vendor doesn’t store or have access to any data and a failure of this vendor would have very little to no impact on your business

Vendor Contracts, Online terms and Policies

Formal contracts or online terms and policies that address relevant security and privacy requirements must be in place for all third parties that process, store, or transmit confidential data or provide critical services. The following must be included in all such contracts (or online terms and policies):

  • Contracts will acknowledge that the third party is responsible for the security of the institution’s confidential data that it possesses, stores, processes, or transmits.
  • Contracts stipulate that the third-party security controls are regularly reviewed and validated by an independent party.
  • Contracts identify information security policies relevant to the agreement.
  • Contracts establish training and awareness requirements for specific procedures and information security requirements.
  • Contracts identify relevant regulations for sub-contracting.
  • Contracts implement a monitoring process and acceptable methods for validating the adherence to security requirements of delivered information and communication technology products and services.
  • Contracts implement specific processes for managing information and communication technology component lifecycle and availability and associated security risks.
  • Contracts identify and outline use of key controls to ensure the protection of organizational assets – e.g. physical controls, controls for protection against malicious code, physical protection controls, controls to protect integrity, availability and confidentiality of information, controls to ensure the return or destruction of information assets after their use, controls to prevent copying and distributing information.
  • Contracts define information security requirements and identify the owner of information and how intellectual property rights are regulated.
  • Contracts identify the recourse available to Bangkok Solutions should the third party fail to meet defined security requirements.
  • Contracts establish responsibilities for responding to direct and indirect security incidents including timing as defined by service-level agreements (SLAs).
  • Contracts specify the security requirements for the return or destruction of data upon contract termination.
  • Responsibilities for managing devices (e.g., firewalls, routers) that secure connections with third parties are formally documented in the contract.
  • Contracts stipulate geographic limits on where data can be stored or transmitted.

Vendor Services Change Management

Changes to the provision of services by vendors, including maintaining and improving existing information security policies, procedures and controls, should be managed, taking account of business information criticality, systems and processes involved and re-assessment of risks. The following aspects will be considered:

  • Changes to supplier agreements;
  • Changes made by the organization to implement:
    • Enhancements to the current services offered;
    • Development of any new applications and systems;
    • Modifications or updates of the organization’s policies and procedures;
    • New/changed controls to resolve security incidents and improve security.
  • Changes in supplier services to implement:
    • Changes and enhancement to networks;
    • Use of new technologies;
    • Adoption of new products or newer versions/releases;
    • New development tools and environments;
