If you can deploy an intelligent device or application component that can shun an attacker after repeated attempts, then that would be beneficial. In some countries, laws define what kind of personal information is allowed to be not only logged but also analyzed. Therefore it becomes very trivial for the attacker to exploit known vulnerabilities in any Web application. this contact form These tools should be combined with web server, J2EE application server, and operating system tools to create the full system/application security overview.

Out of memory, null pointer exceptions, system call failure, database unavailable, network timeout, and hundreds of other common conditions can cause errors to be generated. Logs should be written so that the log file attributes are such that only new information can be written (older records cannot be rewritten or deleted).
