8. Information about Risk Management System used by the Payment Organization
8.1. In the presence of mandatory provisions of the legislation in force in the territory of the state, excluding the application of contractual terms in relations related to the implementation of activities by the Payment Organization, the abovementioned mandatory provisions shall have priority over the terms and conditions set out in the Rules.
8.2. Any discrepancies between the Settlement Participants, the Payment Organization, related to the implementation of activities by the Payment Organization, which may serve as the basis for the emergence of the need for judicial consideration of disputes, shall be considered based on the pre-trial claim procedure.
8.3. The claim of the Settlement Participant, set out in writing on official letterhead signed by its authorized official, shall be sent to the other party by registered mail or by other means confirming delivery of the claim to the addressee. The claim must be filed within 10 (ten) business days after the grounds for the claim arose, and contain the circumstances serving as the basis for its filing, as well as the date of occurrence of the abovementioned circumstances. Claims received after the expiration of the specified period will not be taken into consideration.
8.4. Consideration of claims includes the study of circumstances that allow establishing the fulfillment (non-fulfillment) by the Settlement Participants of their functions and obligations arising from these Rules and the agreements concluded therewith. The Payment Organization may request from the Settlement Participants any information necessary to clarify the aforementioned circumstances.
8.5. Resolution on the claim must be made within 15 (fifteen) calendar days from receipt of the claim and sent to the Settlement Participant in writing.
8.6. If it is impossible to resolve disagreements in the claim procedure, the disputes shall be resolved in the competent court of the Republic of Uzbekistan.
9. Procedure for Settling and Resolving Disputes with Clients
9.1. The Settlement Participants and the Payment Organization shall maintain confidentiality of non-public information about other Settlement Participants that has become known to the Settlement Participants in connection with accessing these Rules, except for cases when such information:
- was disclosed upon the request or with the permission of the Settlement Participant who is the owner of this information;
- is subjected to provision to third parties in the amount necessary to fulfill the obligations stipulated by these Rules;
- requires disclosure on the grounds stipulated by the legislation of the Republic of Uzbekistan.
9.2. Provision of confidential information to a third party for the purpose of fulfilling the Rules and other agreements of the Settlement Participants; provision of confidential information upon the legal request of law enforcement and other authorized state bodies, as well as in other cases stipulated by the applicable legislation of the Republic of Uzbekistan shall not constitute a violation of the confidentiality and security of the Settlement Participants.
9.3. The Payment Organization shall ensure the uninterrupted functioning of the System in 24/7/365 mode (24 hours a day, 7 days a week, 365 days a year), except for the time necessary for maintenance.
9.4. The Payment Organization and the Settlement Participants shall take all necessary measures to ensure the security and protection of information and documents exchanged within the Payment Organization or which are available to the Settlement Participants in connection with the use of the system, as well as for the purpose of identifying (preventing) fraud and combating the legalization of proceeds from crime, financing of terrorism and financing of proliferation of weapons of mass destruction.
9.5. The means and measures to prevent unauthorized access to software and hardware used in the Payment Organization, including software and hardware protection tools, must ensure the level of information protection and maintenance of its privacy in accordance with the requirements established by the legislation of the Republic of Uzbekistan. The Settlement Participants shall take all necessary measures to maintain confidentiality, prevent unauthorized use and protect identification data from unauthorized access by third parties.
9.6. Fault tolerance:
The fault tolerance of the service is ensured by distributing the load between two application servers. In case of unavailability of one of the servers (communication channel drop, high current load, server failure), all requests will be without delay automatically switched to the server that remains online. Thus, a balance is achieved in the performance of the servers in the basic operating mode and ensures uninterrupted transaction processing in the event of unforeseen circumstances, when one of the servers temporarily fails for some reason. The database server operates in the Master-Slave replication mode with a backup server, and in the event of a failure of the main server, the transaction processing nodes are automatically switched to the backup one.
9.7. Backup:
The database server is backed up using built-in MySQL tools. The backup scheme is as follows: every hour + final at 1:00 with deletion of hourly copies. Backups older than one month are deleted in order to prevent the data storage from overfilling. The relevance and preservation of the transaction processing system code base is ensured by the version control system.
9.8. Use of cryptographic data protection methods:
The payment organization uses cryptographic data protection methods when storing confidential information in databases, when transmitting confidential information via communication channels, and when verifying payment transactions for integrity and authenticity.
All cryptographic protection tools are represented by built-in modules of corresponding components of the information system and repeat the life cycle of the component in full.
Key information is generated as part of the commission. Backup storage of key information, if necessary, is ensured in accordance with the instructions of the manufacturer of the cryptographic tool in compliance with the best practices in the field of cryptographic protection tools.
9.9. Server infrastructure access security:
Administrative access to any of the servers is possible only with a 2048-bit SSH2-RSA key. It is impossible to gain access to the server infrastructure by brute-forcing passwords or any other unauthorized means. Client access to the personal account, as well as access of the Payment Organization administrator to the transaction management account, is carried out only through two-factor authorization.
9.10. Anti-fraud:
All transactions with payment cards after their transfer from the System service to the bank's payment system pass through the anti-fraud filter. Based on a set of rules, such as the presence of a card mask for sale on the black market, the reliability of the IP address from which the transaction is made, the use of a TOR client, etc., the filter calculates the risk level of the transaction and assigns it a certain rating. Depending on the level of transaction reliability set by the merchant, the bank's system processes or rejects the transaction.
10. Procedure for Compliance with Information Security Measures
10.1. Changes and/or additions to the Rules may be made either by approving a new version of the Rules or by preparing the text of changes and/or additions to the Rules.
10.2. If the Participant disagrees with the changes and/or additions to the Rules, the Participant may refuse further use of the System.
10.3. Subsequent changes and/or additions to the Rules may be made in the manner prescribed in this section of the Rules.
10.4. Further use of the Payment Organization after the entry into force of any changes and/or additions to the Rules means the Participant’s consent with such changes and/or additions.
