Threats from the Internet

Instant Expert: Computer Viruses
—Instant Expert: Computer Viruses—
Any computer connected to the internet faces a daunting range of electronic threats. Perhaps the biggest single threat to any computer is the humble software bug. Seemingly innocuous programming errors can be exploited to force entry into a computer and also provide the weak spots that allow computer worms and viruses to proliferate.
Many software bugs will simply cause a computer to crash. But an expert programmer can sometimes figure out how to make a computer malfunction in a creative way, so that it provides access to secure parts of a system, or shares protected data.
When a software vulnerability is revealed, it is often a race against the clock to apply the correct software patch before an attacker can convert the bug into an “exploit” that can be used to cause major damage.
Viruses and worms
A computer virus is a program that spreads between computers by hiding itself within a - seemingly innocent - document or application. A worm, on the other hand, is a program that replicates and travels without “infecting” anything else on a system.
Many modern specimens of malevolent code, however, use a mixture of tricks to cheat their way onto computer systems, blurring the line between worms and viruses. The terms are now often used interchangeably.
The first worms appeared in the 1970s and spread slowly between computers connected to the same network. They simply displayed an annoying message on the screen of each infected machine. The first computer virus, called Elk Cloner, was written in 1982 and infected computers via floppy disks. (more…)
