  Managing a corporate network is becoming harder as it becomes larger and more complex. ii. Network management, it includes not only components that transport information in the network, but also systems that generate traffic in the network. iii. The systems could be hosts, database servers, file servers, or mail servers. In the client-server environment, network control is no longer centralized, but distributed. iv. Computer and telecommunication networks are merging fast into converged network with common modes and media of transportation and distribution. As in the case of broadband networks, the IT manager needs to maintain both types of networks. v. Thus, the data communications manager functions and telecommunication manager functions have been merged to that of the IT manager. vi. With the explosion of information storage and transfer in the modern information era, management of information is also the responsibility of the IT manager, with the title of CIO, Chief Information O

  A network operating system is a software application that provides a platform for both the functionality of an individual computer and for multiple computers within an interconnected network. Basically, a network operating system controls other software and computer hardware to run applications, share resources, protect data and establish communication. Individual computers run client operating systems, while network systems create the software infrastructure for wireless, local and wide area networks to function. Basic Operating Features Network operating systems support the basic underlying operating features of networks. These include support for processors and the various protocols that allow computers to share data. Many network operating systems can detect hardware within the system to allow for asset discovery within the network. Also, network operating systems support the processing of other software applications that run on both individual computers and within the network. S

  In the past, wired networks were considered to be far more secure than wireless networks. Today, however, wireless networks are as secure as wired networks, so long as they are properly configured. According to TechTarget, "When comparing wireless vs. wired security, securing a wireless network is even more important than securing a wired network for one simple reason: Accessing a wireless network does not require physical access to a network jack or cable, as does accessing a wired network. Wireless networks use radio transmissions to carry data between end users and the network and it is difficult to contain those radio waves. Therefore, it’s possible for someone to sit in your office building's lobby or parking lot and eavesdrop on wireless network communications." How can MSPs safeguard wireless networks against unauthorized access?

Cyber security or information technology security are the techniques of protecting computers, networks, programs and data from unauthorized access or attacks that are aimed for exploitation. Description: Major areas covered in cyber security are: 1) Application Security 2) Information Security 3) Disaster recovery 4) Network Security Application security encompasses measures or counter-measures that are taken during the development life-cycle to protect applications from threats that can come through flaws in the application design, development, deployment, upgrade or maintenance. Some basic techniques used for application security are: a) Input parameter validation, b) User/Role Authentication & Authorization, c) Session management, parameter manipulation & exception management, and d) Auditing and logging. Information security protects information from unauthorized access to avoid identity theft and to protect privacy. Major techniques used to cover this are: a) Identificatio

 If you're having trouble signing in to your Microsoft account, there could be a few different reasons for that – like you can't remember your password, have two-step verification turned on, or are travelling or using a new device. Here are some suggestions to help you get back into your account as quickly as possible. First, try the easiest options: If you remember your password but it isn’t working, make sure that Caps Lock is turned off and that your email address is spelled correctly. Clear your browser history, or try signing in to your account from a different internet browser. If these don't help get you back in to your account, try resetting your password or see if one of the other scenarios below applies to you and give them a try. If you forgot your microsoft account password and can't remember , reset it Follow these steps to create a new one: Go to the Reset your password page. Choose the reason you need your password reset, then click Next. Enter the email

 Effective information security program management should achieve the outcomes defined in ISG. The necessary goals must be defined in specific, objective and measurable terms. Appropriate metrics should also be put in place to measure whether or not the goals were achieved. If not, it should be known by how much the objectives were missed, and discussion done to improve on performance. Candidates should focus on the following six outcomes, and they should be considered as the basis for developing the objectives of an effective information security program: Strategic alignment: The emphasis here is on organizational information risk, selection of appropriate control objectives and standards, agreement on acceptable risk and risk tolerance and definitions of financial, operational and other constraints. Risk management: Candidates must show a comprehensive understanding of threats the organization faces, its vulnerabilities and risk profile. Candidates must know how to evaluate the poten

 Ransomware is malicious software that infects your computer and displays messages demanding a fee to be paid in order for your system to work again. This class of malware is a criminal moneymaking scheme that can be installed through deceptive links in an email message, instant message or website. It has the ability to lock a computer screen or encrypt important, predetermined files with a password. Examples of Ransomware Scareware is the simplest type of ransomware. It uses scare tactics or intimidation to trick victims into paying up. It can come in the form of fake antivirus software in which a message suddenly appears claiming your computer has various issues and an online payment is necessary to fix them! The level of this type of attack varies. Sometimes, users may be bombarded with endless alerts and pop-up messages. Other times, the computer will fail to work at all. Yet, another type of ransomware can impersonate a law enforcement agency by opening up a page that appears to b

 A LAN (local area network) interconnects several computers using Ethernet technology. As technology advances, networking capabilities have begun shipping as a standard feature on most motherboards. Onboard LAN is a specialized chipset on the motherboard designed to handle networking responsibilities for the computer, such as home networking and Internet connectivity. Local Area Networking Local area networks connect several computers within a limited physical proximity via Ethernet cables or wireless Ethernet, such as in homes, schools or businesses. In early computers, this capability was not a standard feature and required the installation of a network interface card (NIC). NIC installation was necessary until LANs became more common, requiring more efficient and less expensive networking capabilities.
