Administrative Share
Administrative shares are hidden network shares created by Windows NT family of operating systems that allow system administrators to have remote access to every disk volume on a network-connected system. These shares may not be permanently deleted but may be disabled. Administrative shares cannot be accessed by users without administrative privileges. Share names Administrative shares are a collection of automatically shared resources including the following: * Disk volumes: Every disk volume on the system is shared as an administrative share. The name of these shares consists of the drive letters of shared volume plus a dollar sign ($). For example, a system that has volumes C, D and E has three administrative shares named C$, D$ and E$. (NetBIOS is not case sensitive.) * OS folder: The folder in which Windows is installed is shared as admin$ * Fax cache: The folder in which faxed pages and cover pages are cached is shared as fax$ * IPC shares: This area, which is used for in ...

Network Share
In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network. It is a device or piece of information on a computer that can be remotely accessed from another computer transparently as if it were a resource in the local machine. Network sharing is made possible by inter-process communication over the network. Some examples of shareable resources are computer programs, data, storage devices, and printers. E.g. shared file access (also known as disk sharing and folder sharing), shared printer access, shared scanner access, etc. The shared resource is called a shared disk, shared folder or shared document The term ''file sharing'' traditionally means shared file access, especially in the context of operating systems and LAN and Intranet services, for example in Microsoft Windows documentation. Though, as BitTorrent and similar applications became available in the early 2000s, the term ''file sharing' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O'Reilly Media
O'Reilly Media (formerly O'Reilly & Associates) is an American learning company established by Tim O'Reilly that publishes books, produces tech conferences, and provides an online learning platform. Its distinctive brand features a woodcut of an animal on many of its book covers. Company Early days The company began in 1978 as a private consulting firm doing technical writing, based in the Cambridge, Massachusetts area. In 1984, it began to retain publishing rights on manuals created for Unix vendors. A few 70-page "Nutshell Handbooks" were well-received, but the focus remained on the consulting business until 1988. After a conference displaying O'Reilly's preliminary Xlib manuals attracted significant attention, the company began increasing production of manuals and books. The original cover art consisted of animal designs developed by Edie Freedman because she thought that Unix program names sounded like "weird animals". Global Network Navigator In 1993 O'Reilly Media creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Vulnerabilities
Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system. Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware. Vulnerabilities can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. perform unauthorized actions) within a computer system. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerabilities are also known as the attack surface. Vulnerability management is a cyclical practice that varies in theory but contains common processes which include: discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat. This practice generally refers to software vulnerabilities in computing systems. Agile vulnerability management refers preventing attacks by ...

Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan horses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conficker
Conficker, also known as Downup, Downadup and Kido, is a computer worm targeting the Microsoft Windows operating system that was first detected in November 2008. It uses flaws in Windows OS software and dictionary attacks on administrator passwords to propagate while forming a botnet, and has been unusually difficult to counter because of its combined use of many advanced malware techniques. The Conficker worm infected millions of computers including government, business and home computers in over 190 countries, making it the largest known computer worm infection since the 2003 Welchia. Despite its wide propagation, the worm did not do much damage, perhaps because its authors – believed to have been Ukrainian citizens – did not dare use it because of the attention it drew. Four men were arrested, and one pled guilty and was sentenced to four years in prison. Prevalence Estimates of the number of infected computers were difficult because the virus changed its propagation a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Access Protection
Network Access Protection (NAP) is a Microsoft technology for controlling network access of a computer, based on its health. With NAP, system administrators of an organization can define policies for system health requirements. Examples of system health requirements are whether the computer has the most recent operating system updates installed, whether the computer has the latest version of the anti-virus software signature, or whether the computer has a host-based firewall installed and enabled. Computers with a NAP client will have their health status evaluated upon establishing a network connection. NAP can restrict or deny network access to the computers that are not in compliance with the defined health requirements. NAP was deprecated in Windows Server 2012 R2 and removed from Windows Server 2016. Overview Network Access Protection Client Agent makes it possible for clients that support NAP to evaluate software updates for their statement of health. NAP clients are compute ...

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

My Network Places
My Network Places (formerly Network Neighborhood) is the network browser feature in Windows Explorer. It was first introduced in Windows 95 and Windows NT 4.0 and was renamed My Network Places in Windows 2000 and later. My Network Places maintains an automatically updated history of computers which the user has accessed before, by default placed in a folder called , found in the user's user profile. This default location can be changed by modifying the pair of registry entries found under the registry keys and . The feature also allows enumerating all computers on the local network that support the Server Message Block (SMB) protocol and are open to discovery. In a workgroup of fewer than 32 computers,Windows XP help file, "My Network Places overview" the list of network destinations in My Network Places is generated by one of the computers on the network, which has been designated "Browse Master" (sometimes called "master browser"). The Browse Master is elected by system strengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed File System (Microsoft)
Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency (via the namespace component) and Redundancy (via the file replication component). Together, these components enable data availability in the case of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, the "DFS root". Microsoft's DFS is referred to interchangeably as 'DFS' and 'Dfs' by Microsoft and is unrelated to the DCE Distributed File System, which held the 'DFS' trademark but was discontinued in 2005. It is also called "MS-DFS" or "MSDFS" in some contexts, e.g. in the Samba user space project. Overview There is no requirement to use the two components of DFS together; it is perfectly possible to use the logical namespace component without using D ...

Server Message Block
Server Message Block (SMB) is a communication protocol originally developed in 1983 by Barry A. Feigenbaum at IBM and intended to provide shared access to files and printers across nodes on a network of systems running IBM's OS/2. It also provides an authenticated inter-process communication (IPC) mechanism. In 1987, Microsoft and 3Com implemented SMB in LAN Manager for OS/2, at which time SMB used the NetBIOS service atop the NetBIOS Frames protocol as its underlying transport. Later, Microsoft implemented SMB in Windows NT 3.1 and has been updating it ever since, adapting it to work with newer underlying transports: TCP/IP and NetBT. SMB implementation consists of two vaguely named Windows services: "Server" (ID: LanmanServer) and "Workstation" (ID: LanmanWorkstation). It uses NTLM or Kerberos protocols for user authentication. In 1996, Microsoft published a version of SMB 1.0 with minor modifications under the Common Internet File System (CIFS ) moniker. CIFS was compatible w ...

Windows Domain
A Windows domain is a form of a computer network in which all user accounts, computers, printers and other Principal (computer security), security principals, are registered with a central database located on one or more clusters of central computers known as Domain controller (Windows), domain controllers. Authentication takes place on domain controllers. Each person who uses computers within a domain receives a unique user account that can then be assigned access to resources within the domain. Starting with Windows Server 2000, Active Directory is the Windows component in charge of maintaining that central database.Northrup, Tony''Introducing Microsoft Windows 2000 Server'' Microsoft Press, 1999. The concept of Windows domain is in contrast with that of a workgroup (computer networking), workgroup in which each computer maintains its own database of security principals. Configuration Computers can connect to a domain via LAN, Wide area network, WAN or using a Virtual private ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
