What type of combination should be avoided for security?

1. Sequential numbers

2. Random numbers

3. Numbers that are easily guessed

4. All of the above

The correct answer is: All of the above

All of the mentioned types of combinations should be avoided for the sake of security, as they either facilitate unauthorized access or make it easier for someone to bypass security measures. Sequential numbers, such as 1-2-3-4 or 5-6-7-8, follow a predictable pattern that makes them relatively easy for someone to guess. Similarly, combinations made up of easily guessed numbers, like a birthdate or a significant anniversary, can often be deduced by individuals who know the user well or who can conduct minimal research. Random numbers, while generally more secure than sequential numbers, can sometimes fall short if they are not implemented correctly. For instance, if a system allows users to select a random combination from a set of familiar patterns or limited options, it may unintentionally create vulnerabilities. In securing a system, it’s important to use uniquely generated combinations that do not conform to easily recognizable patterns or commonly used numbers, thereby ensuring a higher level of protection against unauthorized access. Therefore, avoiding all these combinations is essential for maintaining security integrity.
