Monitoring and Control technologies: These are the data sources that SIEM will receive. Correct configuration and knowledge of this controls is the base of a good analysis. Some examples of technologies of this category are: Perimeter security solutions: Firewall, VPN, Proxy Network security solutions: NAC, IDS/IPS, vulnerability scanner Endpoint security solutions : Antivirus, DLP, EDR Infrastructure monitoring tools Applications and OS logs 3. Incident response technologies: In case of an incident, it is necessary to have tools to allow the identification of the involved devices, recover affected files, analyze event logs.
