ProcessThe GC optimization process is similar to the process of most performance improvements. Here is the GC optimization process I used.1. monitor GC statusFirst you need to monitor the GC to check the various states of the GC during system execution. Please refer to the monitoring method mentioned in the previous article to become a JAVAGC expert part ii-How to monitor the Java garbage collection mechanism.2. After analyzing the monitoring results, decide whether to perform GC optimizationAs

As mentioned in the netspi blog, you can export the creden。 added later in sqlserver after logging on to the DAC. According to msdn, these creden。 are generally windows user names and passwords, which may be useful during Intranet penetration.

1. Manage Non-Restricted Processes
Non-Restricted processes run in non-restricted domains. For example, the init process runs in the unrestricted initrc_t domain, the unrestricted kernel process runs in the kernel_t domain, and the unrestricted user runs in the unconfined_t domain. SELinux policy rules still apply to non-restricted processes. However, rules that allow processes to run in non-restricted domains allow almost all accesses. Therefore, if a non-restricted process is controlled by hac

detailed financial reports of enterprises in the first half of this year, however, at the same time, access from other departments should be rejected. The centralized or distributed access control method previously introduced is not suitable for this scenario. At this time, we need to use the following data access control methods.
In the CBK of cissp, five data access control methods are most commonly used: independent access control (DAC) and Mandat
