Artigo 12.o 2.

Os procedimentos, protocolos e ferramentas de registo referidos no n.o 1 devem conter todos os elementos seguintes:

a) 

A identificação dos eventos a registar, o período de conservação dos registos e as medidas para proteger e tratar os dados dos registos, tendo em conta a finalidade para a qual os registos são criados;

b) 

O alinhamento do nível de pormenor dos registos com a sua finalidade e utilização, a fim de permitir a deteção eficaz de atividades anómalas, tal como referido no artigo 24.o;

c) 

O requisito de registar eventos relacionados com todos os elementos seguintes:

i) 

controlo lógico e físico do acesso, tal como referido no artigo 21.o, e gestão da identidade,

ii) 

gestão da capacidade,

iii) 

gestão das alterações,

iv) 

funcionamento das TIC, incluindo as atividades dos sistemas de TIC,

v) 

atividades de tráfego da rede, incluindo o desempenho da rede de TIC;

d) 

Medidas para proteger os sistemas de registo e as informações que constam dos registos contra a manipulação, a supressão e o acesso não autorizado aos dados conservados, em trânsito e, se for caso disso, em utilização;

e) 

Medidas para detetar uma falha nos sistemas de registo;

f) 

Sem prejuízo de quaisquer requisitos regulamentares aplicáveis ao abrigo do direito da União ou nacional, a sincronização dos relógios de cada um dos sistemas de TIC da entidade financeira com base numa referência temporal fiável e documentada.

Para efeitos da alínea a), as entidades financeiras devem estabelecer o período de conservação, tendo em conta os objetivos empresariais e de segurança da informação, o motivo para registar o evento nos registos e os resultados da avaliação do risco associado às TIC.

Normas
NOREA Security Monitoring (SIEM)

Put in place mechanisms to detect anomalous activities, including network performance issues, incidents (reported by the third-parties in the services that they provide), and potential material single points of failure. The mechanisms shall enable multi-layers of control, define alerting thresholds, monitoring on specific events and criteria to automatically trigger incident response. Identify and implement tools generating alerts of anomalous activities and behaviour, at least for ICT assets and information assets supporting critical or important functions. Devote sufficient resources to detection and monitoring activities, especially to cybersecurity attacks.
NOREA Event Identification for Logging

Identify events to be logged, covering logical access, physical access, identity management, capacity management, change management, ICT operation (including system activity), and network traffic activities (including network performance). Determine the level of detail for the logs, aligning with the purpose for which the logs were created and to enable effective detection of anomalous activities. Define retention periods for logs, considering business and security objectives, the purpose of recording logs, and risk assessments.

*Data reporting service providers shall, in addition, have in place systems that can effectively check trade reports for completeness, identify omissions and obvious errors, and request re-transmission of those reports.
NOREA Secure Handling of Log Data
Implement measures to secure and handle log data, taking into account the purpose for which the logs were created. Establish measures to detect failures in logging systems. Protect the recording of anomalous activities against tampering and unauthorised access at rest, in use, where relevant, and in transit.
NOREA Error Handling and Recovery
Establish guidelines for handling errors, including support and escalation contacts, as well as external support contacts in case of unexpected operational or technical issues. Define the procedures for ICT system restart, rollback, and recovery to be used in the event of an ICT system disruption. Ensure the contact details are available in case systems are unavailable as well.
NOREA ICT Monitoring

Develop, document and implement capacity and performance management procedures to identify capacity requirements of their ICT systems and apply resource optimisation and monitoring procedures to maintain and improve the availability of data and ICT systems and efficiency of ICT systems and prevent ICT capacity shortages.
NOREA Clock Synchronization Standardization

Ensure clock synchronization of all ICT systems to a single reliable reference source time.
NOREA System Management and Security

Provide system descriptions that encompass secure installation, maintenance, configuration, and deinstallation/disposal of ICT assets. This includes the management of assets, both automated and manual, and the identification and control of legacy ICT systems.
