Purpose of audit:Records events at the core layer, reads and writes files, and calls from the system. Permission statusBelongs to the kernelSyslog purpose:Belongs to the application layer and records all application-layer error messages.Audit has three operating toolsThree commands available for audit:=> Auditctl-controls the kernel audit system, which can be used to retrieve, add, or delete rules, and set the watch for a specific case ).=> Ausearch-the tool used to check the Audit audit logs.=>

Related ConceptsConcurrency and parallelismThese two nouns are concepts in concurrent programming, which can be explained in the context of the garbage collector. Parallel (Parallel): Refers to multiple garbage collection threads working in parallel, but at this point the user thread is still in a wait state. Concurrency (Concurrent): User threads are executed concurrently with the garbage collection thread (but not necessarily in paralle

Java heap is not the same as the method area, where memory allocations are uncertain, and only when the program is running can you know which objects are being created, and this part of the memory and recycling is dynamic, and the garbage collector is concerned about this part of memory.Memory allocation and recycling in the "static" area is clear, but how does the "dynamic" area determine which memory to recycle and which memory should not? As we al

Java heap memory is divided into two parts of the new generation and the old generation, the new generation mainly uses the replication and labeling-clearing garbage collection algorithm, the old generation mainly use tag-sorting garbage collection algorithm, so in Java virtual for the new generation and the old generation of different garbage collectors, JDK1.6 in sun The garbage collector for the hotspot virtual machine is as follows:If the two garb

), weak references (Weak Reference), virtual references (Phantom Reference) These 4 kinds of references are under the Java.lang.ref package:　　Strong references (Final Reference)Refers to references that are common in program code, such as Object obj = new Object (), as long as a strong reference exists, and the garbage collector never reclaims the referenced object.strong references have the following three features:1. A strong reference can directly

1. Serial Collector The serial collector is a single thread collector, but its "single-threaded" meaning does not simply mean that it uses only one CPU or a collection thread to do the garbage collection, and more importantly, when it does garbage collection, all the other worker threads must be paused until the collection is complete. Serial

PrefaceGarbage collector is the previous chapter of the garbage collection algorithm theoretical knowledge of the specific implementation of the different virtual machines provided by the garbage collector may be a great difference, and we must explain in advance that there is no best garbage collector, more than a universal

The garbage collector is a special feature that distinguishes Java from other programming languages. It frees programmers from the heavy work of manually reclaiming memory space. In the Java Programmer certification exams of SUN, the garbage collector is mandatory and generally accounts for about 6% of the total score. But because SUN's Java Programming Language SL-275 curriculum standard textbooks, the con

efficiency is very high. According to the characteristics of the Cenozoic, there are few objects that still exist, but what to do if a survivor space cannot provide enough space for the surviving object to be stored. The answer is to go to the old age to rent a little memory for emergency In some extreme cases, the target survival rate may be 100%, when more memory needs to be requested from the old age One, serial collector Cenozoic collectors, usi

The garbage collector is a specific implementation of memory recycling, the Java virtual machine specification does not specify its implementation, different vendors, different versions of the virtual machine provides a large variety of garbage collectors.
