Which of the following statements is CORRECT?

(6)Say goodbye to those eight-letter passwords. The 12-character era of online security is upon us. accord-ing to a report published this week by the Georgia Institute of Technology. The researchers used clusters of graphics cards to crack eight-character passwords in less than two hours. But when the researchers applied that same processing power to 12-charactcr passwords, they found it would take 17.134 years to make them snap. "The length of your password in some cases can dictate the vulnerability." said Joshua Davis, a research scientist at the Georgia lech Research Institute. It’s hard to say what will happen in the future, but for now. 12-character passwords should be the standard, said Richard Boyd, a senior research scientist who also worked on the project. The researchers recommend 12-character passwords as opposed to those with 11 or. say. 13 characters because that number strikes a balance between "convenience and security". Passwords have gotten longer over time, and security experts are already recommending that people use full sentences as passwords.
