The three major types of malicious activities that organizations and information systems face include:

1. Hostile or malicious insider activity.
2. Theft of private, proprietary, or sensitive data, by insiders or external attackers.
3. Large scale DoS (denial-of-service) attacks.

Based on your research:

• Describe a present-day example of your selected type of malicious activity and its impact on the organization.
• Specify the countermeasures the organization took to address the malicious activity.
• Recommend at least one additional preventative countermeasure and at least one countermeasure organizations could take to address this type of activity once it has occurred.
