Information security monitoring

Information security monitoring is a continuous monitoring of system events that allows you to detect and eliminate the risks of data loss.

What is information security monitoring for?

In the actual operation of servers, monitoring information security events solves many tasks at once:

  • early detection of attacks (DDoS, brute-force, exploits);
  • monitoring the actions of users and administrators;
  • preventing data leaks;
  • compliance with regulatory requirements and standards (ISO 152-FZ, GDPR);

Without constant monitoring, you will learn about problems either from the client or from the logs after the fact.

What is information security event control?

Information security monitoring is the collection, comparison, and analysis of events from universal infrastructure components.:

  • servers,
  • applications,
  • databases,
  • authentication systems,
  • network equipment.

Events and incidents: what is the difference?

The conceptWhat is it in practice?
EventFact: login, error, request, configuration change
The incidentConfirmed: threat or security breach

Classification of data

  • system (OS logs, hypervisor);
  • applied (CMS, CRM, database);
  • network (firewall, IDS/IPS);
  • custom ones.

Key tasks of the monitoring system

  • Centralized event collection.
  • Correlation and anomaly detection.
  • Prioritization of incidents.
  • Automatic response (locks, notifications).
  • Reporting process.

Security Architecture: Tools of 2026

Modern monitoring is not built around a single product, but around an ecosystem.

1

SIEM the brain of monitoring systems

  • the system aggregates actions;
  • identifies attack chains;
  • generates incidents.
2

XDR and EDR endpoint protection

  • server and VM monitoring;
  • detection of malicious activity;
  • real-time reaction.
3

DLP information leak monitoring component

  • analysis of transmitted data;
  • protection of personal and commercial information.
4

SOAR reaction automation

  • response scenarios;
  • reducing the load on the SOC;
  • reduction of MTTR by several times.

Adjusting incident monitoring

We always start with:

  • customer infrastructure analysis;
  • definitions of critical assets;
  • correlation rule settings;
  • testing attack scenarios.

Ready-made templates without adaptation are a direct route to false positives.

Monitoring information security activities as a service

Advantages of the service

  • 24/7 monitoring cycle without hiring SOC;
  • hosting provider's expertise;
  • transparent reporting;
  • scaling for project growth.

Do not delay the connection

In 2026, the question is no longer "will an accident happen", but "will you notice it in time".

Information security tracking is the foundation of stability, customer trust, and continuous system operation.

A practical case

Background information:

The client is a SaaS system on a VPS cluster (12 virtual servers), a database of personal information of users, peak load of up to 20,000 sessions per hour. Information security monitoring is enabled as part of the service.

What happened

  • SIEM recorded a series of uncharacteristic SQL queries from one of the backend servers.
  • At the same time, EDR noted the start of a process in the system that was not present in the baseline of the fileserver.
  • The actions individually looked uncritical, but the correlation revealed the chain of attack.

How the monitoring worked

1

The correlation of incidents in SIEM related:

  • abnormal database access;
  • process privilege escalation;
  • outgoing traffic to an unknown IP.
2

SOAR automatically:

  • isolated the fileserver at the network level;
  • blocked the user's session;
  • created a case of high criticality.
3

The SOC engineer connected within 7 minutes.

Result

The attack turned out to be an attempt to exploit a vulnerability in an outdated API module. The container was updated and reassembled before the attacker gained access to the information.

Conclusion

Without monitoring, the case would have been discovered after a leak based on user complaints or abnormal traffic.

It was the SIEM EDR automated response bundle that made it possible to stop the attack at the incident stage, rather than the consequences.
