Windows Forensics The Windows operating system has come a long way. You literally can’t do anything in Windows without it being logged somewhere. It is important that you understand some of the common functions of the Windows OS. Let’s look at some commands and tools that will help identify current settings and possible vulnerabilities.  As a cyber professional you will want to become very comfortable typing commands at the Windows command prompt. Here are two easy ways to access the command prompt:      Press Win-R to open a Run window, then type cmd and press Enter or the OK button. To open an Administrator command prompt (if needed), type cmd and press Ctrl-Shift-Enter.     Press Win-X to open the Power Users menu, then select either Command Prompt or Command Prompt (Admin) as needed.

A Computer Forensics Lab (CFL) is a designated location for conducting computer-based investigation of the collected evidence in order to solve the case and find the culprit. The lab houses the instruments, software and hardware tools, suspect media, and the forensic workstations required to perform investigation of all types. Setting up a forensics lab includes: Planning and budgeting Before planning and evaluating the budget for the forensic investigation case, consider the following:     Break down costs into daily and annual expenditure     Refer to the investigation expenses in the past     Be aware of updated technology     Use of statistics to obtain an idea about the computer crimes that are more likely to occur Physical location and structural design considerations     Make sure the lab room is secured     Heavy construction materials need to be used     Make sure lab exteriors have no windows     E...

 Nmap is an open source network monitoring and port scanning tool to find the hosts and services in the computer by sending the packets to the target host for network discovery and security auditing. Numerous frameworks and system admins additionally think that its helpful for assignments, for example, network inventory, overseeing administration overhaul timetables, and observing host or administration uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. it runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, t...
