Samhain v2.6.0 released
The samhain open source host-based intrusion detection system (HIDS) provides file integrity checking and logfile monitoring/analysis, as well as rootkit detection, port monitoring, detection of rogue SUID executables, and hidden processes.
It has been designed to monitor multiple hosts with potentially different operating systems, providing centralized logging and maintenance, although it can also be used as standalone application on a single host.
Samhain is a multiplatform application for POSIX systems (Unix, Linux, Cygwin/Windows).
- Supported platforms:
- POSIX (e.g. Linux, *BSD, Solaris 2.x, AIX 5.x, AIX 4.x, HP-UX 10.20, HP-UX 11, Unixware 7.1.0, Alpha/True64, and Mac OS X)
- Windows 2000 / WindowsXP with POSIX emulation (e.g. Cygwin)
- PCI DSS Compliance:
- The Payment Card Industry (PCI) Data Security Standard (DSS) mandates the use of file integrity monitoring software.
- Centralized management: Samhain can be used standalone on a single host, but its particular strength is centralized monitoring and management. The complete management of a samhain system can be done from one central location. To this end, several components are required.
- The samhain file/host integrity checker
- The yule log server
- A relational database
- The beltane web-based console
- The deployment system
- File integrity checks:
- Scheduling of file checks
- Host integrity monitoring:
- Logfile monitoring/analysis
- Kernel integrity
- SUID/SGID files
- Open ports
- Process check
- Mount check
- Login/logoff events
- Log facilities: The verbosity and on/off status of each log facility can be configured individually.
- Integration with other systems / Active response
- Generic interfaces
- Active response
- Integrity of the samhain system: There is always a trade-off between security and convenience, and thus you may want to keep your file checking executable on disk and hope that an intruder will not tamper with it. Samhain offers the following features to help protecting its integrity:
- signed database and configuration file
- embedded password
- compiled-in key
- daemon mode
- signed reports
