What are the main security issues associated with networked systems and how can they be overcome?

Introduction

There are a number of means in which a networked computer system along with its content may face security issues in the form of network attacks. Majority of such attacks integrate the employment of malicious software which is jointly termed as malware. This type of software may be executed on, and transferred to the computer itself, or it may hit on a computer from a remote location. Such software which are executed on, and transferred to the networked computer systems exposing it to the security issues, count in; spyware, Trojan horses, worms, and viruses.

Virus

Virus is referred to software which taints a networked computer system by slotting itself into the software programs which are already installed in the system. After that, when the execution of host program takes place, virus is also executed with it. On execution, several viruses cause harm or damage to the system apart from just transferring itself to different programs installed in the computer system.

Worm

Worm refers to an individual program which gets transferred by means of a network, occupying a space in networked systems and advancing its copies to different systems. A typical outcome of a worm is a detonation of its replicated imitates which deteriorates the efficiency of the authorized applications and may eventually put an added burden on the internet or the entire network.

Trojan Horse

Trojan Horse is a program which gets into a networked computer system camouflaged like a desired program, like a useful package of utility or a game, which is imported by the victim at will. Nevertheless, after entering into the system, the Trojan Horse executes supplementary activities which may pose ...
