Expresso Framework is an open standards-based J2EE architectural framework that allows the developer to concentrate on application logic. It is a library of extensible Java Server application framework components for creating database-driven Web applications based on open standards. Expresso integrates with Apache Jakarta Struts, which emphasizes presentation and application configuration, and bringing a powerful tag library to Expresso. Expresso adds capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance, and a JSP tag library.
Firewall Log Daemon is a program written in C which will watch for ipchains or iptables log alerts in realtime. The program will start a small daemon process that parses and resolves firewall logs by reading a FIFO that syslog writes to. It can queue a batch of alerts and mail them to you, or can be used in a script to crunch an existing log file or data stream. It features hostname, port, protocol, and ICMP type/code lookup, with output formatted by a user-defined template.
Log4j is a logging package written in Java. Log4j allows you to log to a file, a java.io.Writer, a remote server, or a syslog daemon. The package is designed so that log statements can remain in shipped code without incurring a high performance cost. One distinctive feature of log4j is the notion of hierarchical loggers. Using hierarchical loggers, it is possible to select (at runtime) which log statements are output at arbitrary granularity. Users can choose to implement their own log formats and output strategies.
logsurfer is a log checking/auditing tool similar to swatch and logcheck but with the capability of handling multi-line messages and dynamically adapting the ruleset. It is written in portable C, well documented, fast, and flexible. It works on any textfile or stdin, can be run at intervals or continuously, and has timeouts and resource limits.
md5mon is a shell script that verifies files by computing their checksums. The script is suitable for use as a basic security checking tool from cron. It features configurable monitoring levels, local copies of find/md5sum, and integrity checks to prevent tampering with itself. It can also use a more secure shasum instead of md5sum.
The modular syslog allows for an easy implementation of input and output modules. The modules that mantain compatibility with its precursor are included in the standard distribution along with four modules: om_peo (an implementation of PEO-1 and L-PEO, two algorithmic protocols for integrity checking), om_mysql and om_pgsql (modules that sends output to a mysql and postgresql database, respectively) and om_regex (a module that allows output redirection using regular expressions).
