In vulnerable versions of indy-node, an attacker can max out the number of client connections allowed by the ledger, leaving the ledger unable to be used for its intended purpose. However, the ledger content will not be impacted and the ledger will resume functioning after the attack. This attack exploits the trade-off between resilience and availability. Any protection against abusive client connections will also prevent the network being accessed by certain legitimate users. As a result, validator nodes must tune their firewall rules to ensure the right trade-off for their network's expected users. The guidance to network operators for the use of firewall rules in the deployment of Indy networks has been modified to better protect against denial of service attacks by increasing the cost and complexity in mounting such attacks. The mitigation for this vulnerability is not in the Hyperledger Indy code per se, but rather in the individual deployments of Indy. The mitigations should be applied to all deployments of Indy, and are not related to a particular release."}, {"lang": "es", "value": "indy-node es la parte del servidor de Hyperledger Indy, un libro de contabilidad distribuido dise\u00f1ado para la identidad descentralizada. En las versiones vulnerables de indy-node, un atacante puede superar el n\u00famero de conexiones de clientes permitidas por el libro mayor, dejando el libro mayor incapaz de ser usado para su prop\u00f3sito. Sin embargo, el contenido del libro mayor no estar\u00e1 afectado y el libro mayor volver\u00e1 a funcionar despu\u00e9s del ataque.

Por ello, los nodos validadores deben ajustar sus reglas de firewall para garantizar el equilibrio apropiado para los usuarios previstos de su red. Las orientaciones a operadores de redes para el uso de reglas de firewall en el despliegue de las redes Indy han sido modificadas para proteger mejor contra los ataques de denegaci\u00f3n de servicio, aumentando el coste y la complejidad en el montaje de dichos ataques. La mitigaci\u00f3n de esta vulnerabilidad no est\u00e1 en el c\u00f3digo de Hyperledger Indy per se, sino en los despliegues individuales de Indy.
