Security Adviser columnist Roger Grimes explains that frequently, even as much as once a week, someone will seek his counsel about an unexplainable problem they chalk up to malware. A recent example is, “we upgraded the file servers for a particular application last week, and now we are having random printing problems. Do you think it might be a computer virus?”“They seemed surprised when I tell them I don’t know of a malware program that causes random printing problems on upgraded server applications.” Grimes writes in To solve the unsolvable problem. “What are they thinking?” There is nothing random in the computer world, Grimes continues. “Ask any crypto programmer. They spend their lives trying to create realistic randomness but know it doesn’t truly exist in the computer world. They can get to very good approximations of randomness, but true randomness does not exist.” Security
