*The Centralized Log Management*
In case of a cyber security incident, logs play a important role in various activities such as establishing the point of compromise, tracing the actions of an attacker, further investigation, and regulatory proceedings before an authority, etc.
Logs assist in understanding how changes have taken place in a particular system. By searching, sorting, and filtering the log data, it becomes easy to pinpoint errors, issues, loopholes, or gaps that might have occurred. Manually doing so can be an extremely time-consuming process as one needs to look at thousands of log entries coming from big numbers of log files. In order to make this entire process easy, you need a Centralized Log Management system.

Collecting Evidence from Network Infrastructure Devices -
You can collect a lot of information from network infrastructure devices, such as routers, switches, wireless LAN controllers, load balancers, firewalls, and many others that can be very beneficial for cyber forensics investigations. You may make sure it can hold several months of events. As you may have learned, syslog is often used to centralize events. You should also increase the types of events that are logged—for example, DHCP events, NetFlow, VPN logs, and so on.
Implementation -
The OZG Digital Forensics Center (ODFC) implements Centralized Log Management (CLM) by aggregating logs from various sources into a unified platform. This process involves collecting, preprocessing, and normalizing log data to enhance accessibility and analysis. The ODFC utilizes a centralized dashboard for real-time monitoring, enabling quick identification of anomalies and security threats through customizable alerts. The system supports compliance by maintaining detailed logs for audits and regulatory requirements, while also employing role-based access controls to secure sensitive information. This streamlined approach enhances operational efficiency and simplifies troubleshooting across IT environments.
*The ODFC handles log data preprocessing and cleaning through several key techniques:*
1. 👁️🗨️ The ODFC employs filtering mechanisms to extract only relevant log data before ingestion, removing unnecessary noise and irrelevant information from the logs.
2. 👁️🗨️ The system standardizes log formats across diverse sources, ensuring consistency and facilitating easier analysis.
3. 👁️🗨️ After filtering, logs are structured into usable formats, enabling efficient searching and correlation of events.
4. 👁️🗨️ Continuous monitoring allows for immediate identification of anomalies, ensuring that only significant events are logged and analyzed.
These steps enhance the accuracy and efficiency of log management, aiding in security and compliance efforts.
