The Network Operating System For Habibi’s Restaurant

Log-on securities ar delicate in protecting the computer network. As a restaurant that engrosss computers to rise faster communication in a more efficient and less term consuming way must be awargon of certain softw ar system updates to find out the safety of the computer services. Defined in Wikipedia (2007), the system must be victimisation the softw be NOS or network operational system hence this controls networking, the messages that comes kindred dealings and queues when many exploiters be utilise the network.The softw be does not only aid in the quick access but it in addition does some administrative break aways and has an especial division when it comes to security. Compared to the functional softwares similar OSs or Windows XP, NOS tramp to evoke the optimum network action and the software is commonly employ in local area networks or to a wide area networks but is to a demerit applicable to a broader wander of networks. NOS are based in the 5 layers of OSI reservoir model.The restaurant could use the latest available NOS like Novell Netware, Windows NT and 2000, Sun Solaris and IBM OS/2 to achieve the best performance in the administrative level. Many important programs are protected by NOS like it could domiciliate back-up for processors, protocols, automatic hardware detection and get multi-processing, warrantor measures like authentication, authorization, logon restrictions and access control. former(a) featured programs are the name and directories, back-up and sideboard services, internetworking or routing and WAN ports. With the use of these external access systems the administration could log on and log off efficiently. The NOS also aid in auditing, graphic interfaces, gather, tolerance to fault and high availability system.In using the Windows legion 2003 the Active Directory compatibility could be enhanced. at that place is also better deployment support when it comes to the innovation like for example from Windows NT 4.0 to Windows innkeeper 2003 and Windows XP Professional. The security department services are answered by changes in the IIS web server. It is rewritten for the enhancement of security.While the Distributed record System call for many functions including the victuals of multiple hosting of DFS single server , last-place server , active directory , print server , and other programs or services. There are refreshed versions of Windows emcee that stop be used via the Remote Desktop communications protocol for terminal services. This program cornerstone have a multiple functions as wellhead as in remote graphical logins for fast performances from the distant server. The IIS as it is used in Windows Server 2003 increases the inadvertence security system because of the built in firewall that rat break defaults. InMarch 2005 new improvements and updates were incorporated to Windows Server 2003 like the Windows XP containing substance abusers like Service subsc ribe 2. The following programs are the updates for Windows Server 2003. (1) There are shelter Configuration Wizard that can enhance the administrators research in making changes and security policies. (2) Another program is Hot patch that allows DLL, the driver and non-kernel patches for a non reboot function. (3)The IIS 6.0 Metabase Auditing is creditworthy in tracking or alter of metabases. (4) The Windows XP Service Pack 2 could be effectively converted to Windows Server 2003 by using the Windows Firewall system. With package like the hostage Configuration Wizard that can be used by the administrators for more yielding designate(postnominal) open ports and hence it can be detected automatically because the default roles could be selected. (5) For the support of IPv6, Wireless Provisioning serve is used.This also builds new defenses against SYN flood transmission control protocol assault. (6) Default modes can be discharge on when a Service Pack 1 server is booted subseque ntly its installation, and is made possible by Post-Setup warranter Updates , hence it configures the firewall to barricade all incoming connections, and able in directing the user for updates installation. (7) Buffering could be prevented if (DEP) or Data implementation Prevention has to be used. The No race (NX) does not allow overflow in particular in cases that there is an attack by Windows Server vectors.The Windows Server 2003 R2 is the newest update with installable features for Windows Server 2003 that includes SP1. The software has many systems of function like (1) Branch Office Server that is actually capable in centralization of tools in the administrator like the agitates and printers, enhancement of Distributed load System (DFS), the WAN data proceeds responsible for Remote Differential Compression. (2) The identicalness element and Access Management for Extranet bingle Sign-On and identity federation, centralization of administration in extranet action acce ss, automated disabling of extranet access in consideration to the Active Directory account information, the user access logging and cross-platform web unity Sign-On and or password synchronization with the use of mesh topology Information Service (NIS). (3) retention Management for the File Server choice Manager that can have a reposition utilization reporting function, enhancement of quota management, the file screening limits files types are allowed and the shop Manager for terminus eye socket Networks (SAN) for the function of storage array configuration. (4) The Server Virtualization serves in the 4 virtual instances. (5) The SDK for UNIX utilities that gives a affluent Unix development environment examples are base of operations Utilities, SVR-5 Utilities, Base SDK, GNU SDK, GNU Utilities, Perl 5, optic Studio Debugger Add-in.The Windows Server 2003 contains Datacenter edition which allows an 8-node clustering that could help lessen fault tolerance. By means of cluste ring, the fault tolerance of server installations is boosted and is accessible. The clustering also supports the file storage that is connected to Storage Area Network (SAN). This could run in Windows and also to non-Windows direct systems as it can be connected to other computers. To block datas or redundancy and to achieve fault tolerance, the Windows Storage Server 2003 uses the RAID arrrays for these functions. A Storage Area Network is available in Windows Storage Server 2003 where the datas are transferred then stored in bigger chunks and not by files. then the datas transferred are more granular, because of that there is a higher performance in database and exertion processing, while it permits NAS devices to get connected in SAN.The Windows Storage Server 2003 R2 has a Single Instance Storage (SIS) contained in the file server to optimize high perfromance. The (SIS) can transfer or scan files in volumes moving it to the common SIS store, thereby reducing the storage bul k by 70%. As stated by Couch (2004) installation of data protection systems like the uninterruptible power supplies (UPS), redundant array of independent disks (RAID), and tape backup systems that are provided by Windows Home Server bequeath aid in the maintenance of the network.ReferencesWikipedia, 2007.
