Detailed explanation-1: -If a password is only four or five characters (whether they are just numbers or a combination of numbers, letters and symbols), there’s a very high chance that it will be hacked instantly. However, if a password is only numbers and up to 18 characters, it could take a hacker up to nine months to crack the code.
Detailed explanation-2: -On average it only takes a hacker two seconds to crack an 11 – character password that only uses numbers. But if you throw in some upper and lower-case letters in there that number changes, taking the hacker 1 minute to hack into a seven-character password.
Detailed explanation-3: -The sooner you identify the breach, the better position you will be in to stop the damage. This raises an important question: How long does it take to find out you have been hacked? The short answer is ‘it depends’-it can take a few minutes, several days, months, or even years to identify a data breach.
Detailed explanation-4: -A flaw in the control systems of server motherboards means they can be tricked into revealing sensitive data to a hacker or even destroying themselves.
