Securing syslog servers and devices
Given that Linux and Unix devices are popular among organizations, securing them requires a solid strategy. One of the necessary components in any organization's security strategy is auditing syslogs. Real-time auditing can provide a clear picture of network activity and alert administrators of any potential breach attempts well in advance.
Using an automated tool like EventLog Analyzer makes auditing syslogs from Unix and Linux devices efficient, continuous, and instantaneous.
Auditing syslog devices with EventLog Analyzer
The advantages provided by EventLog Analyzer include:
- Support for all Unix and Linux devices with a large collection of predefined reports.
- Collection of syslogs through agentless technology, with the option to install agents if needed.
- Centralized normalization and storage of logs.
- Securing and encrypting log archives, with flexible archiving options.
- Notifications about important events, such as critical errors and failed logons, with real-time email and SMS alerts.
- In-depth log forensics with flexible log search options.
EventLog Analyzer predefined syslog reports
EventLog Analyzer provides a wide collection of predefined reports for syslogs from Unix and Linux devices. Syslog reports help administrators secure Unix and Linux devices against insider threats and external breach attempts. EventLog Analyzer provides the following reports:
- Severity: Classifies all events according to their severity level. Warning, critical, and emergency events could indicate a serious network issue. If not corrected in a timely manner, attackers could use some of these issues, such as a flaw in network infrastructure, to their advantage.
- System events: Lists the occurrence of various system events, which can be useful for identifying any abnormal events that require further investigation, such as the unexpected shutdown of a critical server or an application download at an odd hour.
- Logon and user account monitoring: Shows successful and failed user logons, user group changes, and password change attempts that could indicate a malicious insider threat or a compromised user account.
- Data protection: Audits all data systems, such as removable media, network file systems, and FTP operations.
- Auditing sudo command use: Monitors the usage of the sudo command, which allows users to exploit other users' (usually the superuser or other restricted users) security privileges.
- Mail server auditing: Audits mail server activity, revealing interesting trends or anomalies for further investigation, such as when several emails are rejected from a specific domain.
- Network errors: Highlights several types of errors on the network, such as reverse lookup errors or invalid connection errors. These errors are useful for identifying where weak points are on the network.
