To provide services for the central safekeeping of assets, B3´s CSD has a technical and operational structure in place, as well as robust controlling practices, so that it can always be compliance with its legal framework.
B3´s CSD Systems
B3’s Centralized Deposit processes are carried out on the following systems:
- CAC – Centralized deposit of assets
- Cetip/NoMe – Centralized deposit and constitution of liens and encumbrances on assets
- PAE – Registrars’ position control and validation of corporate actions
- RADAR - History and calculation of corporate actions
- SOG - Constitution of liens and encumbrances on assets
- CI.CORP – Remote voting
Certification and testing environment
In addition to the central safekeeping and the constitution of liens and encumbrances systems, the B3´s CSD provides its participants with a specific access to a certification and testing environment that replicates the other ones. This way, participants can proced system requirement verification, performance, stress, and endurance tests, ensuring that the system performance is suitable for use.
IT backup infrastructure
The B3´s CSD processes and systems are covered by B3's business continuity plan, which aims to maintain organizational resilience and the ability to respond to unexpected events.
One of the pillars of B3’s business continuity plan is the IT Disaster Recovery Plan (PTRD), which is responsible for activating the IT backup infrastructure in the event of unavailability of the main IT infrastructure. Data replication between both environments occurs in synchronous mode. B3’s IT backup infrastructure is characterized by high availability and disaster recovery capability: if a specific IT system fails, another resource on the same site can replace it. If the failure occurs in one or more systems on the same site, the backup infrastructure can replace them.
The B3´s CSD has procedures to verify data integrity if processes are interrupted. These verification procedures can be run both on the primary site and on the secondary site after execution of recovery procedures.
