  • All users, significantly affected by a change, shall be notified of the change. The user representative shall sign-off on the change. Users shall be required to make submissions and comment prior to the acceptance of the change.
  • Procedures for aborting and recovering from unsuccessful changes shall be documented. Should the outcome of a change be different to the expected result (as identified in the testing of the change), procedures and responsibilities shall be noted for the recovery and continuity of the affected areas. Fall back procedures will be in place to ensure systems can revert back to what they were prior to implementation of changes.
  • Information resources documentation shall be updated on the completion of each change and old documentation shall be archived or disposed of as per the documentation and data retention policies.
  • Specific procedures to ensure the proper control, authorisation, and documentation of emergency changes shall be in place. Specific parameters will be defined as a standard for classifying changes as Emergency changes.
  • All changes will be monitored once they have been rolled-out to the production environment. Deviations from design specifications and test results will be documented and escalated to the solution owner for ratification.

22.Secure Application development

  • The Secure Application development policy is a plan of action to guide developers’ decisions and actions during the software development lifecycle (SDLC) to ensure software security. This policy aims to be language and platform independent so that it is applicable across all software development projects. 
  • The adherence to and use of Secure Application Development Coding Policy is a requirement for all software development on We Voice information technology systems and trusted contractor sites processing the Company data.
  • Each phase of the SDLC is mapped with security activities, as explained below: a) Design
    • Identify Design Requirements from security perspective
    • Architecture & Design Reviews
    • Threat Modelling
    b) Coding
    • Coding Best Practices
    • Perform Static Analysis
    c) Testing
    • Vulnerability Assessment
    • Fuzzing
    d) Deployment
    • Server Configuration Review
    • Network Configuration Review
  • Development of code shall be checked and validated with the most current versions of We Voice Coding Standards for Secure Application Development. All code developers shall verify that their code is in compliance with the most recent and approved coding standards and guidelines.
  • Only validated code shall be implemented into We Voice production environment. A review and validation ensures that code exhibits fundamental security properties to include correctness, predictability, and attack tolerance.
  • Application Code Developers shall:

  • Ensure code meets the level of confidence that software is free from exploitable code vulnerabilities, regardless of whether they are already designed into the software or inserted later in its life cycle.
  • Ensure code provides predictable execution or justifiable confidence and that the software, when executed, will provide security functionality as intended.
  • Coding techniques must address injection flaws particularly SQL injection,buffer overflow vulnerabilities, cross site scripting vulnerabilities, improper access control (insecure direct object reference, failure to restrict URL access, directory traversal etc.,), cross site request forgery (CSRF), broken authentication and session managment
  • Never trust incoming data to the system, apply checks to this data.
  • Never rely on the client to store sensitive data no matter how trivial.
  • Disable Error messages that return any information to the user.
  • Use object inheritance, encapsulation, and polymorphism wherever possible.
  • Use environment variables prudently and always check boundaries and buffers.
  • Applications must validate input to ensure it is well-formed and meaningful.

23.Penetration testing methodology

  • In this section, should be listed the risks inherent in conducting penetration testing over the information systems of We Voice . Additionally, it should be noted for each mitigation measures that will be taken. Examples might be: Example 1# Risk: Denial of Service in systems or network devices because of the network scans. Mitigation measure 1: network scans must be performed in a controlled manner. The start and end of the scan must be notified to responsible personnel to allow monitoring during testing. For any sign of trouble will abort the scan in progress. Mitigation measure 2: scanning tools must be configured to guarantee that the volume of sent packets or sessions established per minute does not cause a problem for network elements. In this sense, we must perform the first scans in a very controlled way and a use minimum configuration that may be expanded when is evident that the configuration is not dangerous for network devices or servers in the organization.
  • Key staff involved in the project by the organization will be listed:

    Technical Project Manager:

    Chief Information Security Officer:

    Chief Information Officer:

    Head of Communications:

    Responsible for web site YYYY.com:

  • External intrusion tests will be performed remotely from the supplier's premises .Internal intrusion tests will be conducted in the office We Voice of the Organization. Audit team must to have access to the Organization's network. It must manage access permissions to the building early enough to ensure that the audit team can access without problems during planning period.
  • If segmentation is used to limit the scope of PCI DSS the segmentation techniques need to be tested using a segmentation test.
  • All the tests will be conducted from the equipment owned by the audit team so no equipment for the execution of the tests is required. The only requirement in this regard will be to have an active network connection for each member of the audit team. Those connections must provide access to the target network segment in every case.
  • If an incident occurs during the execution of the tests that have an impact on the systems or services of the organization, the incident should be brought immediately to the attention of those responsible for incident management in the project
  • It should be noted that in order to comply with PCI DSS the scope of the test should include, at least the following:
    • All systems and applications that are part of the perimeter of the cardholder data environment card (CDE).
    • Critical systems within the CDE.
  • For all findings or vulnerabilities identified during the tests carried out will be generated and documented sufficient evidence to prove the existence of the same. The format of the evidence can be variable in each case, screen capture, raw output of security tools, photographs, paper documents, etc.

24. Incident Response Plan

'Security incident' means any incident (accidental, intentional or deliberate) relating to your communications or information processing systems. The attacker could be a malicious stranger, a competitor, or a disgruntled employee, and their intention might be to steal information or money, or just to damage your company.

The Incident response plan has to be tested once annually. Copies of this incident response plan is to be made available to all relevant staff members, and take steps to ensure that they understand it and what is expected of them.

Employees of the company will be expected to report to the security officer for any security related issues.

We Voice PCI security incident response plan is as follows:

  1. Each department must report an incident to the Information Security Officer (preferably) or to another member of the PCI Response Team.
  2. The PCI Response Team will investigate the incident and assist the potentially compromised department in limiting the exposure of cardholder data and in mitigating the risks associated with the incident.
  3. The PCI Response Team will resolve the problem to the satisfaction of all parties involved, including reporting the incident and findings to the appropriate parties (credit card associations, credit card processors, etc.) as necessary.
  4. The PCI Response Team will determine if policies and processes need to be updated to avoid a similar incident in the future, and whether additional safeguards are required in the environment where the incident occurred, or for the institution.
  5. If an unauthorised wireless access point or devices is identified or detected as part of the quarterly test this is should be immediately escalated to the Security officer or someone with similar privileges who has the authority to stop, cease, shut down, and remove the offending device immediately.
  6. A department that reasonably believes it may have an account breach, or a breach of cardholder information or of systems related to the PCI environment in general, must inform We Voice PCI Incident Response Team. After being notified of a compromise, the PCI Response Team, along with other designated staff, will implement the PCI Incident Response Plan to assist and augment departments’ response plans.
