Log Analysis

The network devices that we use in computer networks are capable of recording events that occur. With these records, it is ensured that events occurring on the network are confirmed and necessary measures are taken in case of damages. This is called Log Analysis. Log management, which consists of steps such as comprehensive collection, consolidation, preservation of original logs, analysis and presentation as text, provides the indicators and evidence of the attack.

It also helps in forensic investigation of attacks, providing important information on which channels and when the attack was carried out, which protocols were used, and where the attack started. Logs should be monitored daily and real-time alarms should be set for high-risk events.

SIEM (Security Information and Event Management)

Compared to log analysis, it provides better reporting options with its fine-tuned research and advanced system. Many data on an organization’s security are created in multiple locations, and the SIEM system makes it easy to analyze all these data from a single point of view, identify trends, and see unusual patterns. One of the most important features of SIEM is the correlation technique that helps to detect possible attacks by making meaningful connections between events that seem to be independent with the help of determined policies and rules. A SIEM system gathers daily data analysis and many security-related documents for analysis on a single platform. Protecting a business from complex cyber threats is a very difficult process. Visibility and actionability of security threats that appear to be unrelated incidents pose both reputation and financial risk to the organization if it is attempted without a secure advisory service.

In SIEM systems;

The process of converting log records of different formats into a common data is called normalization, the process of establishing a connection between events is called correlation, and the process of reducing the size of the data by allowing multiple recorded events to be unified is called merging.

Importance of SIEM

Threats to network security are spreading rapidly and new ones are emerging every day. With the increase in the number of devices connected to these networks, it also increases the possibility of infiltration into networks. In this case, companies need to analyze the data collected from multiple sources and decide the security steps to be taken in order to detect the threats faced by the network. In this case, our team collects, associates, analyzes and stores logs from security events in networks, hosts, and critical applications. In addition, it uses the essential security features required for complete and effective threat detection, incident response, and compliance management. Our certified security experts work to detect, investigate, and respond to threats in real-time in real time.

Our SIEM / Log management services allow you to better understand the security-related events that occur in your network. In addition, industry regulations such as FISMA, FFIEC, PCI DSS, GLBA, COBIT, ISO 2700, HIPAA and SOX require organizations to protect, back up and analyze log data in their IT infrastructure.

SIEM Stages:

  • Introduction to sizing, reporting and compliance requirements
  • Implementation of log / SIEM infrastructure
  • Support for reporting and configuring alert functions
  • Support for system operations or managed service as needed
  • Continuous support and regular optimization of infrastructure, logging and reporting
