logihallinta

Logihallinta is the Finnish term for log management, referring to the processes and technologies used to collect, store, organize, analyze, and protect event logs produced by information systems, networks, and applications. It supports IT operations, security monitoring, troubleshooting, and compliance by providing visibility into system activity and incidents.

Key activities include collecting logs from servers, network devices, and applications; normalizing and indexing data; storing logs in a central repository; ensuring secure transport and tamper-evident logging; applying retention policies; managing access and data minimization; and performing analysis, alerting, and reporting, often via security information and event management (SIEM) solutions.

Governance and compliance considerations shape logihallinta in practice. EU data protection rules (GDPR) influence what is logged and how long it is kept, with privacy-by-design and strict access controls. Standards such as ISO 27001 and PCI DSS provide guidance on retention, protection, and auditing. Key challenges include data volume, cost, and privacy, while best practices emphasize defined retention schedules, encryption and secure transport, role-based access, data integrity checks, and regular reviews.
