In addition, many organizations rely on SIEM solutions that are limited by cost and capability. ![]() The decentralized approach to log management in their IT environments makes detecting and responding to threats nearly impossible. Chalenge #3: Digital TransformationĪccording to Gartner , many organizations, especially midsize enterprises and organizations with less-mature security operations, have gaps in their monitoring and incident investigation capabilities. In order to absorb and derive valuable insights from all log files in real-time, the data requires a level of normalization to make it easily parsable. Depending on the type of log, the data may be structured, semi-structured or unstructured. Unfortunately, not all log files follow a uniform format. If almost everything produces a log, how can an organization manage the sheer volume of data to quickly realize the full value offered by log files? Challenge #2: Standardization With the rise of the cloud, hybrid networks, and digital transformation, the volume of data collected by logs has ballooned by orders of magnitude. Threat Logs: contain information about system, file, or application traffic that matches a predefined security profile within a firewall.Resource Logs: provide information about connectivity issues and capacity limits.Availability Logs: track system performance, uptime, and availability.Change Logs: include a chronological list of changes made to an application or file.Authorization Logs and Access Logs: include a list of people or bots accessing certain applications or files.Windows, Linux, and macOS all generate syslogs. It includes startup messages, system changes, unexpected shutdowns, errors and warnings, and other important processes. System Log (syslog): a record of operating system events.Server Log: a text document containing a record of activities related to a specific server in a specific period of time.Event Log: a high-level log that records information about network traffic and usage, such as login attempts, failed password attempts, and application events.Because of that, many types of logs exist, including: ![]() Nearly every component in a network generates a different type of data and each component collects that data in its own log.
