The impact of security incidents in today’s computing world is increasing day by day due to the complexity, growing reliance on software with known vulnerabilities, higher user expectations and expanding and changing systems. The computing environment has become highly complex. Networks, operating systems, computers, Web sites, applications, switches, routers, and gateways are interconnected and are driven by hundreds of millions of lines of code. The number of potential entry points to a network expands continually as more devices are added. This will increase the probability of security breaches and other security attacks.
There are various types of computer attacks. Some of the common attacks, including the virus, worm, Trojan horse, spam, …show more content…
To create to create programs to infect documents and templates, attackers are using and application macro language (such as Visual Basic or VBScript). Virus gets executed when an infected document is opened, and damage the user’s application templates. Unwanted words, phrases, numbers, can insert into documents or alter command functions using macros. Once a macro virus get executed and infect the application, it can embed itself in all future documents created with the application. The “WM97/Resume” virus is a Word macro virus spread through email with the subject “Resume - Janet Simons.” If the email recipient clicks on the attachment, the virus deletes all data in the recipient’s mapped drives.
WORMS
Unlike a computer virus, which requires users intervention, a worm is a harmful program that exist in the active memory of the computer .Worms duplicates itself. Worms will cause a series of negative impacts in user’s computers which includes losing of data’s and programs, decreased productivity due to workers being incapable of using their computers, additional productivity loss¬¬¬¬¬ as workers try to recover programs and data’s, Increased effort for IT workers to clean up the and restore everything to as close to normal as possible.
