IoT Challenges
to execute certain security measures, then it would make it less susceptible for attackers to use this force to hack into the user’s system. Some of the precautionary measures
would be:
• Having a complex (e.g., alphanumeric or a mix of special symbols) or lengthy
password.
• Restrict the number of attempts to sign into the account. And in the case of
failure to log in within the given limits, the account should be provisionally
inaccessible. For instance, when one enters the incorrect password multiple
times in a Gmail login, there is a CAPTCHA code automatically sent along with
a request to enter the text in the image sent which is system generated (as shown
in the screenshot in Figure 11.11). This is done to check whether the password
is being entered on its own or is being entered by the human robotically, which
Gmail is unaware of.

The hardware framework of various perceptual end points of an equipment, such as a
computer or peripheral, attached to a network is not very complicated and, therefore,
is susceptible to be duplicated by the hackers.
