2.3.1) The main purpose of the development is to serve as the firmware interface for the next generation of computer products, instead of the widely used BIOS interface of the current PC. With the secure boot feature enabled, Windows 8 can effectively withstand low-level malware attacks, such as rootkits attacks. In an operating system with Secure boot, the system submits the digital signature of all boot components to the system's Anti-
protection measures. Daily scans can detect, isolate, and purge infections that bypass security software monitoring. 4. Install a valid antivirus tool Many computer users believe that the free anti-virus tools provided by Internet service providers through bundled services are effective enough to protect the computer from viruses or spyware. But this is not the case, and there are more and more threats, and these free anti-malware programs are ofte

on real-time systems. However, I often encounter problems caused by dd images. Although VBoxManage can convert the dd image to the VirtualBox disk image format, I usually do not have time or storage space to do so. In this case, xmount can play a major role. Xmount can use memory to quickly convert the dd image/Encase image to Virtualbox format. You only need to connect the disk image to a new virtual machine and use it as the master boot hard disk, modify the CPU, disk, and controller settings

Today's air defense system is no longer a simple defense model that has been pieced together by several weapon systems in the past, but an organic whole composed of various air defense organizations and facilities. It mainly includes: intelligence warning system, command and control system, interception weapon system, and safeguard service system and people's air defense system. It can be said that it is a perfect "Combination" of all defense and attack weapons ". The air defense system has bec

For suspicious or risky software, Kaspersky security force may limit its behavior by 2011, making it unable to access the underlying functions of the system and steal users' private content. It is also worth mentioning that Kaspersky's security force 2011 has excellent performance in resource occupation. If you do not perform a manual scan, it is hard for users to feel the existence of the scan in the computer. In the pa
Introduction All security guides recommend you shoshould have a security audit toolkit (or forensic toolkit or recovery toolkit ). this toolkit is constituted by a set of static-linked binaries (grep, w, netstat, ls, nc, strace, ps... Etc). The problem it that these security guides tell you to build this toolkit but never show you how to do it (they just tell it can be really difficult ...). In this article I will explain why we need this toolkit then I will show how to build it. Note:The "build
