In the context of IT security, monitoring refers to the continuous surveillance of networks, IT infrastructure, or specific applications. The primary goal is to detect and mitigate events and activities that threaten the security, availability, confidentiality, or integrity of systems before they cause harm. Thus, monitoring is a key factor in protecting IT systems and, consequently, the entire business from potential damage.
Modern monitoring solutions are offered as software tools that utilize AI-driven technologies such as machine learning to effectively identify and counteract cyber threats.
Monitoring software enables the oversight of various services and systems. For instance, network components such as Linux or Windows servers and clients can be monitored. The software can be configured to track CPU usage, disk space, and other resources. It sends alerts to administrators when predefined thresholds are breached, such as low disk space or memory, allowing resources to be scaled promptly to prevent system downtime. This helps administrators use resources efficiently and optimize distribution.
Network hardware, including switches, firewalls, routers, and other network devices, can also be continuously monitored to ensure network stability. In the event of hardware failure, the responsible admin can be promptly notified, allowing rapid hardware replacement to minimize system downtime. Additionally, it is advisable to monitor databases such as SQL or services like Active Directory, Exchange, or cloud services in use.
Monitoring tools are particularly useful for the early detection of Distributed Denial of Service (DDoS) attacks. By monitoring network traffic, unusual traffic spikes can be identified early, helping prevent server overload.
Especially in early detection and incident response management, it is crucial to eliminate potential issues that could lead to downtime or disruptions in the business. By recognizing abnormal patterns, signs of cyberattacks like ransomware can be detected early, and countermeasures can be initiated.
Therefore, it is recommended to use monitoring tools that can identify such anomalous patterns and send email alerts to the administrator.
