Silverlight updates. Silverlight will periodically check a Microsoft server for updates to provide you with the latest features and improvements. A small file containing information about the latest Silverlight version will be downloaded to your computer and compared to your currently installed version. If a newer version is available, it will be downloaded and installed on your computer. You can turn off or configure updates in the Silverlight Configuration tool.
The actual collection of the evidence involves the preservation of volatile evidence and the powering down of digital devices. The state of operation of the digital devices encountered will dictate the collection procedures. For instance, if a computer is encountered, if the device is on, volatile evidence (e.g., temporary files, register, cache, and network status and connections, to name a few) is preserved before powering down the device and collecting it (Casey, 2011; Sammons, 2012; Maras, 2014; Nelson, Phillips, and Steuart, 2015). If the device is off, then it remains off and is collected (US National Institute of Justice; 2004b; US National Institute of Justice, 2008). There are circumstances where digital devices will not and cannot be collected (e.g., due to size and/or complexity of the systems and/or their hardware and software configurations, because these systems provide critical services) (see Cybercrime Module 4 on Introduction to Digital Forensics). In these situations, volatile and non-volatile data are collected through special procedures that require live acquisition ( SWGDE Capture of Live Systems , 2014). The type of digital device encountered during an investigation will also dictate the manner in which digital evidence is collected (see, for example, SWGDE Best Practices for Mobile Device Evidence Preservation and Acquisition, 2018; SWGDE Best Practices for the Acquisition of Data from Novel Digital Devices; US National Institute of Justice, 2007a).
Different approaches to performing acquisition exist. The approach taken depends on the type of digital device. For example, the procedure for acquiring evidence from a computer hard drive is different from the procedure required to obtain digital evidence from mobile devices, such as smartphones.
Gratuitous Address Resolution Protocol is used in advance network scenarios. It is something performed by computer while booting up. When the computer booted up (Network Interface Card is powered) for the first time, it automatically broadcast its MAC address to the entire network. After Gratuitous ARP MAC address of the computer is known to every switch and allow DHCP servers to know where to send the IP address if requested. Gratuitous ARP could mean both Gratuitous ARP request and Gratuitous ARP reply, but not needed in all cases. Gratuitous ARP request is a packet where source and destination IP are both set to IP of the machine issuing the packet and the destination MAC is the broadcast address ff:ff:ff:ff:ff:ff ; no reply packet will occur. Gratuitous ARP is ARP-Reply that was not prompted by an ARP-Request. Gratuitous Address Resolution Protocol is useful to detect IP conflict. Gratuitous ARP is also used to update ARP mapping table and Switch port MAC address table.
The Digital Random Number Generator, using the RDRAND instruction, is an innovative hardware approach to high-quality, high-performance entropy and random number generation. To understand how it differs from existing RNG solutions, this section details some of the basic concepts underlying random number generation.
With respect to the RNG taxonomy discussed above, the DRNG follows the cascade construction RNG model, using a processor resident entropy source to repeatedly seed a hardware-implemented CSPRNG. Unlike software approaches, it includes a high-quality entropy source implementation that can be sampled quickly to repeatedly seed the CSPRNG with high-quality entropy. Furthermore, it represents a self-contained hardware module that is isolated from software attacks on its internal state. The result is a solution that achieves RNG objectives with considerable robustness: statistical quality (independence, uniform distribution), highly unpredictable random number sequences, high performance, and protection against attack.
A Scaler for Every DisplayThrough a distributed scaler approach, the DMPS3-300-C affords a very flexible and user-friendly solution for handling multiple disparate display devices. Employing discrete outboard scalers like the HD-SCALER-HD-E, DM-RMC-SCALER-C, and DM-RMC-4K-SCALER-C, the DMPS3-300-C allows an independent high-performance scaler to be installed at each display device, ensuring an optimal image on every screen no matter what sources are selected.[7]
TeamViewer Host is used for 24/7 access to remote computers, which makes it an ideal solution for uses such as remote monitoring, server maintenance, or connecting to a PC or Mac in the office or at home. Install TeamViewer Host on an unlimited number of computers and devices. As a licensed user, you have access to them all!
Answer #30: CMS developed a downloadable schema validator tool that plans and developers can use to assess whether their machine-readable files are compliant with the Transparency in Coverage JSON schema. The validator tool and instructions can be accessed here. The tool can be used to validate In-Network rate and Allowed Amount files, as well as provider references and table of contents files. Note that the tool tests for attributes required under version 1.0 of the JSON schema and for syntax errors, but does not test the accuracy of the data in the schema. It is designed to run on local computers and can be used to validate files of any size (there is no file size limit). At this time, the validator tool can only be used to validate JSON files. 153554b96e
