  Accounting information systems (AIS) simplify financial reporting for purposes of making well-informed decisions. They include all the components of the accounting process: people, procedures, data, software, devices and security. The software is on a device like a computer, and the security is incorporated in the software. People put together procedures and enter data into the accounting software. Types of AIS by Processing Mode Batch processing systems, online batch systems and online real-time systems are the three types of accounting information systems classified by mode of processing. In batch processing systems, you enter transactions when they occur and periodically process and integrate the transactions into the accounting record by running a batch process either daily or weekly. Online batch systems are the same as batch processing systems, except that you record transactions and process batches using online-based accounting software. When using an online real-time system,

  The components used to establish a local area network (LAN) have a variety of functions. The common unifying theme among them is that they facilitate communication between two or more computers. LAN components are configurable in a variety of ways, but a LAN always requires the same basic components. Network Cards At the most basic level, a network card is a component that allows the computer to communicate across a network. This component is frequently built into the motherboard of today's computers, but it can also be a separate card for use in a PCI slot, or part of an external unit that connects to the computer via a USB port. Network cards are further categorized according to whether they operate on wired or wireless networks. However, some cards do support both wireless and wired networking. Network Cables Network cables are the physical lines used to carry information between computers in a wired LAN. The cables are labeled by their category and are commonly referred to as

  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 mechanisms3 know more :  3 dom

 1. Improve your password security. It may sound simple or obvious, but better passwords really can help protect your business. The fact is, people are still using bad passwords. Research from a password management security company suggests that nearly 10 percent of people have used have used one of 25 of the "worst passwords" which include "123456", "password", and "starwars". Yes, starwars. 2. Add a critical layer of protection. Another way to improve your network security is to partner with an expert. There are many qualified firms that can help you monitor and protect your critical business systems – this might be an especially good option if your firm lacks the dedicated IT resources needed for network security.  Look for a reputable vendor that can provide a customized level of network monitoring and support. 3.  Establish a backup plan to avoid data loss.  A data backup plan will help you preserve critical data so that you can keep your bu

  The LM hash is the old style hash used in Microsoft OS before NT 3.1. Then, NTLM was introduced and supports password length greater than 14. On Vista, 7, 8 and 10 LM hash is supported for backward compatibility but is disabled by default. The goal is too extract LM and/or NTLM hashes from the system, either live or dead. These hashes are stored in memory (RAM) and in flat files (registry hives). If LM hashes are enabled on your system (Win XP and lower), a hash dump will look like: Administrator:500:01FC5A6BE7BC6929AAD3B435B51404EE:0CB6948805F797BF2A82807973B89537::: If LM hashes are disabled on your system (Win Vista, 7, 8+), a hash dump will look like: Administrator:500:NO PASSWORD*********************:0CB6948805F797BF2A82807973B89537::: The first field is the username. The second field is the unique Security IDentifier for that username. The third field is the LM hash and the forth is the NTLM hash. More about :  lm hash cracker

  CCM, located in Microsoft Windows' System32 folder, stands for Change and Configuration Management. It's a folder created to store temporary files for client installations as a part of the Systems Management Server (SMS) of Microsoft, which is responsible for deploying system-wide installations and updates. Background SMS was Microsoft's enterprise management software that tracks hardware and software inventories, deploys software applications and updates and manages any software changes in a network environment. By 2007, this has become System Center Configuration Manager, which essentially performs the same tasks as SMS. Process SMS or SCCM centralizes the process of software installation into one management application. When a new software or update needs to be deployed, it creates the CCM folder in all computers until the installation or update finishes. The CCM folder contains the Advance Client Installer (ccmsetup.exe), which is responsible for initiating the instal

  Many people will probably tell you that you need some form of degree in computer science, but that isn’t necessarily the case. Like most technical jobs there are a few qualifications and certificates you may need. One of the top qualifications you will benefit from is a CCNA, which is a Cisco Certified Network Associate certification. It will test both your theory of computer networking but also your practical knowledge in which you might be asked to do within a junior networking engineering role. As a well-respected certification in the industry not only do you look qualified but companies are aware that these tests are difficult to take. Employers For most employers they like to know the network engineer they are employing has some form of technical knowledge, giving them a level of assurance you will know what to do when you start a new role. Having well-qualified network engineers gives makes the company more reliable to work with for customers and helps to boost profitability. P

  When building a local network, you probably use a mix of computers, including Windows PCs and Apple Macs. Though OS X and Windows are built quite differently, they can be networked through file sharing services built into each operating system. On Macs, you turn file sharing on in the System Preferences menu. Then, using a Windows computer, you can connect to those shared folders by using the local IP address of the Mac computer. Step 1 Turn on both the Mac and PC computers, and ensure that they are connected to the network. Step 2 Click the Apple icon, then "System Preferences" and then "Sharing" on your Mac. The Sharing window appears. Step 3 Select "File Sharing" from the services pane on the left-hand side of the window. Step 4 Write down your Mac's IP address. It is located under the "Windows Sharing: On" section of the file sharing window, denoted by "afp:\192.168.1.102" where "192.168.1.102" represents your Mac

  When it comes to cloud services and software-as-a-service (SaaS), we're all familiar with the usual cloud providers. But for small businesses and larger enterprises, there's a huge world of opportunity and available resources beyond those best-known cloud storage and cloud computing services: Google, Dropbox, Salesforce, Amazon and Microsoft. In this guide to services for business, we're looking at 24 incredibly valuable services that solve real-world business problems. A few of you may have heard about before. Many may be new to you. All are capable of providing nearly instant benefit -- without you having to make any infrastructure investment whatsoever. Often, these bottlenecks aren't because a higher-up didn't actually want the project to go through, but simply never got around to signing off. The approval email might have gotten lost or, if you're still on paper approvals, buried in a huge inbox mound. If you're dealing with accounting and finance app

  The network manager job description and responsibilities can be varied -- depending in part on whether the organization relies on a managed service provider -- but generally, the network manager role includes the following duties: ·           Managing and maintaining the network, as well as network performance monitoring ·           Identifying, installing and maintaining upgrades to the network ·           Troubleshooting and repair ·           Overseeing user access to the network ·           Developing a backup/disaster recovery plan for a network emergency ·           Planning network infrastructure for new applications and services ·           Training network staff to provide support to end users ·           Purchasing and maintaining networking equipment and infrastructure ·           Integrating mobile devices into the organization's networks, either (or both of) organizational and personal devices (BYOD) In a large enterprise, network manager job responsibilities may ext

  Route reflectors are networking routing components specific to border gateway protocol, commonly known as BGP. Route reflectors are an alternative to the full-mesh requirement of internal BGP (IBGP), and act as a focal point for IBGP sessions. Because route reflectors can propagate IBGP routes to other IBGP peers, a full mesh of IBGP peers is not necessary. The concept of a route reflector is consistent across IP version 4 as well as 6, but the topology used here refers to IPv6. In the diagram below, the red dotted lines represent external BGP relationships, while the blue dashed lines reflect the internal neighborships within the AAS. The Role of Route Reflectors If R3 follows the rule and does not advertise the prefix to its internal neighbors, R4 and R5 will not learn it. The purpose of route reflectors is to fix that problem. To do so, the route reflector simply instructs R3 that, when it receives an advertisement from an IBGP neighbor (in this case, R2), it should break the rule
