Also called malware, malicious software, or computer virus, malware attacks on computer networks and releases malicious code that replicates itself into other programs. Malware is often created by viruses. Viruses are malicious computer viruses that duplicate themselves, infecting other computer programs on a computer network but not spreading to other computer networks when the infected machine connects to the main infected site. Some malware is developed by hackers as a means to steal private information like credit card numbers and bank account information from a computer or network.
An infection from malware can create several problems
including reducing the performance of the operating system, disabling some software programs and devices and sometimes disrupting network communications. Some infections do not destroy the hard disk of a computer system. Malware usually comes in the form of a program that runs when a computer is started up. Since most malware runs hidden in other applications, most users do not see any infections when they start their computer or connect to the Internet.
A Malware infection starts with an attempt to gain access to a particular piece of data from a client company server. For example, a client company might give permission for an application to access certain files when it is installed on a client’s computer system. The installation of software or other devices may open communication channels between the Malware attacker and the host machine. In some cases, the client company’s server is compromised by an external source and the compromise creates a gateway through which the Malware spreads throughout the network system. In this instance, Malware may be termed as a Mobile Malware or a Computer Network Malware infection.
An infection from Malware in this fashion may affect the operations of the company’s internal network, or it may affect the communications services of the organization. The infected communication services include data networks like the Internet, cell phone networks, voice networks, email services, video communications services, and the operation of business applications like ERP and CRM. The Internet is the biggest mode of Malware distribution; however, the data transmission within it is usually secured by subscriber authentication. Therefore, the data received from clients and servers using cell phone networks may be vulnerable to Malware in this manner. The Malware spreads in other ways such as emails from a remote client device, messages in instant messengers, instant messaging applications, and even from some specific images stored on web pages.
Mobile Malware is not technically termed as Malware.
It is more commonly referred to as Mobipocket, Moxie, GSM (Global System for Mobile Communication) phones, and the like. Mobile Malware can affect any type of computer network based on the communication protocols being used. The most common means of delivery for Malware are through SMS, MMS (Mobile Messaging Service), Short Message Service, and data packets in wireless networks such as GSM. It is similar to Malware because it has the capacity to corrupt a host computer data system. However, unlike Malware, mobile Malware generates mobile-specific application that runs within the mobile network environment.
Cloud Computing is a new generation of managed service providers or cloud computing. It has emerged from the need for IT solutions for the growth of the internet. It is a utility computing model for the delivery of computing resources over the internet. This model helps to create large volumes of virtual resources with shared resources such as storage, memory, computation power, processing speed, bandwidth and power. These resources are then accessed or used by application programs and the users in a virtual environment.
The advantages of cloud computing are:
It reduces costs and deployment time of application. It provides guaranteed availability of critical resources. It enables the providers to increase revenues by automating processes. It helps to manage infrastructure and customer data in a better way. On the whole, the Cloud architecture helps the clients to provide an improved user experience and to obtain maximum benefits from their infrastructure investment.
Thus, both SaaS and in-house can be benefited by a good communication and technical partnership.
- A SaaS application can be delivered to any location provided by an in-house IT staff.
- It will be entirely managed by the SaaS provider.
- The benefits of in-house IT support and maintenance are completely eliminated with the use of SaaS.
- Thus, these are some of the benefits of a managed services provider.
