In case of a cyber security incident, logs play a vital 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 are generated by every application, let it be a general application like performance monitoring or security specific application like a firewall.
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 hundreds of log files.
In order to ease this entire process, many solutions such as a Centralized Log Management (CLM) solution comes into the picture.
Defining Centralized Log Management System
A Centralized Log Management System, or a CLM system, is a type of logging solution which collects your log data from multiple sources and consolidates the collected data. This consolidated data is then presented on a central interface which is easy-to-use as well as easily accessible. The primary motive behind the development of CLM systems is to cut-short the frustrating process of manually going through a plethora of log data and hence, making the life easier for an internal security team.
Apart from various data collection features, an ideal CLM system is also expected to support analysis of log data and clear presentation of outcomes after analysis.
Capabilities of Centralized Log Management System
A CLM system provides the following capabilities to your organization –
- Centralized storage for log data coming in from multiple sources
- Implementing log retention policies so that log data irrelevant to security is deleted after a specific time period
- Easily searching and sorting through thousands of log entries
- Defining organization-specific metrics for generation of alerts
- Access to multiple users of internal security team at the same time
- Easier user access management on a single centralized platform
- Simpler process for meeting performance, availability, compliance, and security requirements
- Cheaper and affordable log management as compared to managing logs on a specific system
Centralized Log Management & SIEM
For SIEM solutions like that of Logsign, log data is a backbone and irreplaceable. An ideal SIEM solution combines log data and state data to give you a detailed overview of your organization’s security. This, in turn, forms the foundation for the majority of security-related decisions for your organization. Many SIEM-as-a-service providers put limitations on log data collection due to their pricing model. Hence, you must thoroughly check the pricing model before availing the services from a third-party service provider.
We have discussed multiple times previously that absolute security is a myth and no one has a universal weapon against the risks posed by these threats. The actors with malicious intent are always going to be there no matter what and they will keep on finding new and unique ways to break into organizational systems such as website, network, applications, or firewall. However, having an efficient SIEM solution with centralized log management system can indeed make a significant difference between staying on top in this digital battle or losing it and maybe, going out of the business.
