how windows 7 lanmanserver working?

Network camera support in Windows is continuing to improve, with additional functionality currently available for developers enrolled in the Windows Insider Program. In the latest insider builds, developers will find improved support for more ONVIF cameras, as Windows is now fully certified by ONVIF. Additionally, there are some new APIs available in the insider builds that enable streams from a specified RTSP Uniform Resource Identifier (URI), and to perform time synchronization with cameras. The two APIs are described below. For streaming from a URI through the MediaCapture class, assign the desired URI to MediaCaptureInitializationSettings::DeviceUri. If credentials are required, they can be set through MediaCaptureInitializationSettings::DeviceUriPasswordCredential. The API supports ONVIF and generic RTSP server URIs. This allows applications to use the standard Windows Media APIs to capture video from generic cameras that do not conform to the ONVIF standards, or from an arbitr

Telecommunication and Network Security

Telecommunication and network security is one of the most technical domains of the CISSP credential because it requires an understanding of network infrastructure, methods of communication, formats for transporting data, and measures taken to secure the network and transmission. The network is the vital link connecting information resources to users. Thus, this domain focuses on the design and architecture of the network and its components to prevent the disruption of data flow and intrusion. The key components of this domain are: Confidentiality Network security protocols Network authentication services Data encryption services Integrity Firewall services Communications security management Intrusion detection services [and intrusion prevention systems] Availability Fault tolerance for data availability (backups, redundant disk systems) Acceptable logins and operating process performance Reliable and interoperable security processes and network security mechanisms

what is efficient Password Cracking Where LM Hashes

Sometimes you end up with a great many Windows domain passwords that need cracking – either because you have compromised the domain controller and exported them yourself, or because the client has asked you to perform a password audit and has supplied the database to you themselves. As you know, LM hashes are insecure, and there is a very good way of cracking these (Ophcrack). However, there will also be passwords that cannot be cracked using the standard tables, or maybe the LM hash is not present in the dump at all. In this case, we’ll need to attack the NTLM hash with another tool – in this case a GPU cracker known as Oclhashcat. In this case we have a large (something like 6,000 entry) pwdump format file, with LM and NTLM hashes. Because the LM hashes have various weaknesses in the cryptography, we can crack a lot of passwords using Ophcrack – but in some cases only NTLM hashes are present. In this case we can use a hybrid approach. find more :  l m hash cracker

Windows 7 Support is Over, Here’s Everything You Need to Know About It

The Redmond software giant is ending support for its most popular product ever - Windows 7. An update on the Windows lifecycle fact sheet page points that Windows 7 Service Pack 1 will stop receiving updates on January 14, 2020. As you may remember, support for Windows 7 RTM without service packs ended on April 9, 2013. Today, Microsoft terminates support for Windows 7 SP1. The OS can be considered classic software and it is widely used by users all over the world. Mainstream support for Windows 7 ended back in 2015. Since that time the OS hasn't received any new feature. After January 14, 2020, Windows 7 PCs will stop receiving security updates. They will become more vulnerable to security risks. Windows will operate but your data may stay unsecure. Microsoft is also offering paid Extended Security Updates (ESU). The ESU offer has been available in the Volume Licensing Service Center (VLSC) since April 1, 2019. Windows 7 remains a very popular operating system as of thi

History of Network Operating Systems

Nowadays, practically every personal computer is connected in one form or another to a network. There exists of course the biggest network of all —the Internet— but several other types of smaller networks like LANs (local area networks) and enterprise networks also exist. Network operating systems (NOS) serve as gatekeepers to data and applications on all manner of these networks. Network operating systems don't differ too much from the single-processor operating systems almost every computer user is familiar with, says Andrew Tannenbaum in his book "A History of Operating Systems", but they have their own unique, fascinating history. Birth of Networks The concept of data communications between computers began in the late 1960s and early 1970s, when researchers began developing a way of connecting computers and exchanging information by way of packets of data. Soon, the concept of a local area network (LAN) took hold, replacing the previous model of a central computin
