A Comprehensive Guide to Information and Cyber Security from a CISSP perspective

What is Information and Cyber Security?
Information and Cyber Security refers to the practices and techniques utilized to protect electronic data from unauthorized access, use, disclosure, disruption, modification, or destruction, with the goal of ensuring confidentiality, integrity and availability.
Why it is Important?
With the increasing dependency on technology for day-to-day functions, protecting information and systems from cyber threats has become paramount. This involves guarding digital properties, sensitive data, and personal information from a range of threats such as data breaches, cyber-attacks, and identity theft.
How it Works?
Information and Cyber Security involves measures like setting strong passwords, using network security tools, conducting regular backups, keeping software updated, and educating users about potential threats. On an organizational level, it may involve multi-layered defense strategies, security policies and procedures, security awareness training, and incident response plans.

Question 1

Your company has experienced a ransomware attack. Your team has isolated the infected system. What is the next best step to take?

Remove the infected system and restore from backup Reinstall the operating system and start over Try to decrypt the data using available tools Pay the ransom to retrieve the data

Correct Answer: Remove the infected system and restore from backup

The best option is to remove the infected system and restore from a known good backup to minimize downtime and loss. Paying the ransom doesn't guarantee data recovery and can encourage future attacks. Reinstalling the OS without restoring from a backup can lead to data loss. Trying to decrypt data without known methods can be time-consuming and unsuccessful. While disconnecting the network prevents further spread, it doesn't resolve the issue or recover the data.

Question 2

Your organization is experiencing an email-based phishing campaign targeting users. As the security lead, what is the best approach to prevent further attacks?

Implement employee security awareness training and email filtering Implement a web content filtering solution Require additional password changes Block all incoming emails

Correct Answer: Implement employee security awareness training and email filtering

Employees are the first line of defense against phishing attacks. Implementing security awareness training and email filtering will help prevent these attacks. Blocking all incoming emails is not practical. Web content filtering solutions don't target email threats. Additional password changes and disabling email attachments can be disruptive, and creating a new email domain doesn't address the root cause.

Question 3

Your organization recently implemented a new application that handles sensitive data. You notice that users are creating weak passwords. What is the best solution?

Disable user accounts Implement password complexity requirements Decrease lockout threshold Force users to change passwords every week

Correct Answer: Implement password complexity requirements

By implementing password complexity requirements, you ensure users select strong and secure passwords. Disabling user accounts is disruptive and not an effective solution. Forcing users to change their passwords frequently can lead to insecure password choices. Decreasing the lockout threshold can lock out valid users. Allowing users to self-manage their passwords can lead to weak passwords, and disabling password history can lead to repeated passwords.
