How does the speed of attacks factor make security increasingly difficult?
What will be an ideal response?
The challenge of keeping computers secure has never been greater. A number of factors have converged to make security increasingly difficult. One is the speed of attacks that occur today. With modern tools at their disposal, attackers can quickly scan systems to find weaknesses and then launch attacks with unprecedented speed. For example, the Slammer worm infected 75,000 computers in the first 11 minutes after it was released, and the number of infections doubled every 8.5 seconds. At its peak, Slammer was scanning 55 million computers per second looking for another computer to infect. Later that same year, the Blaster worm infected 138,000 computers in the first four hours and ended up infecting over 1.4 million computers. Many attack tools can now initiate new attacks without any human initiative, therefore increasing the speed at which systems are attacked.
