intrusion detection system software

OpenVAS is an open vulnerability assessment tool used to detect the security of the target network or host. Similar to the X-Scan tool of security focus, OpenVAS uses some open plug-ins earlier than Nessus. OpenVAS can work based on the C/S (Client/Server) and B/S (Browser/Server) architecture. The administrator can issue scanning tasks through a browser or a dedicated client program, server-side load authorization, perform scan operations and provide scan results. A complete OpenVAS

application and calls hooks Based on win APIs. 12. sapmemory analyzer-is an open-source Java memory analysis software that can be used to help find memory leaks in Java programs. It is easy to find large memory blocks and verify who is occupying it all the time, it is based on Eclipse RCP (rich client platform) and can download the RCP independent version or Eclipse plug-in. 13. dtrace-dynamically tracks Dynamic Tracing. It is an open-source

System Performance Detection, Performance monitoring focuses on computer system resource monitoring, which is necessary for preventive maintenance of the system. You can analyze the monitoring data to understand the bottlenecks of the system, measures should be taken to adju

View system startup kernel detection hardware information dmesg, kernel dmesg Dmesg is used to display the boot information. The kernel stores the boot information in the ring buffer. You can use dmesg to view the information if you cannot view it at startup. The boot information is also saved in the/var/log directory and named dmesg. Dmesg is used to detect and control the kernel ring buffer. Programs are

If present the speed is affected cannot be avoided. I. Problems caused by operating system hardware and software factors Problem Appearance

Sneak through the site and see some good Linux performance testing tools. Worry about forgetting to make a record here. If there is a wrong place, or insufficient, and usually do not use much, but the force of the tool also please see this blog post of comrades to make a lot of suggestions. Thank you!Dstat ToolsDescription: Dastat This software is dainty, package size is only 144k, installation size 660k. This tool dynamically displays----total-cpu-us

Mcelog is a tool used on x86 Linux systems to check for hardware errors, especially memory and CPU errors.For example, the server is inexplicably restarted over time, and message and syslog do not detect valuable information.The cause of the MCE error usually occurs as follows:1, memory error or ECC problem2. Processor Overheating3. System bus Error4, CPU or hardware cache errorIn general, when there are error prompts, you need to pay attention to mem
