Why is it important to rename a system default account?
What will be an ideal response?
All operating systems come with a preinstalled user account (or accounts). This account - for example,"root"in the UNIX operating system or "administrator" in Windows operating systems - generally has administrative access to the system and is used to create additional accounts. Attackers know which default accounts are included with an operating system, so these accounts need to be renamed. By doing so, you force attackers to spend more time discerning or guessing a username.
