Review Questions

• How does malware impact modern businesses, and what measures can be implemented to mitigate these effects?
  • Malware significantly impacts modern businesses by causing data breaches, financial losses, and operational disruptions. To mitigate these effects, organizations should implement robust cybersecurity measures such as regular software updates, use of firewalls, and employee training programs. By enhancing awareness about malware threats and encouraging safe online practices among employees, businesses can reduce the likelihood of successful malware attacks.
• What are the different types of malware, and how do they vary in their methods of attack and impact?
  • There are several types of malware, including viruses that replicate themselves and spread through systems, ransomware that locks files until a ransom is paid, and spyware that gathers user information without consent. Each type varies in its attack method; for example, while viruses spread through infected files, ransomware typically targets critical data directly. Understanding these variations helps organizations prepare specific countermeasures tailored to each malware type.
• Evaluate the role of firewalls and intrusion detection/prevention systems in defending against malware attacks within an organization’s cybersecurity framework.
  • Firewalls and intrusion detection/prevention systems play a pivotal role in defending against malware attacks by monitoring network traffic and blocking unauthorized access attempts. Firewalls act as a barrier between trusted internal networks and untrusted external networks, filtering out harmful traffic. Intrusion detection/prevention systems actively analyze traffic patterns for suspicious activities related to malware. Together, these tools enhance an organization's ability to detect potential threats early and respond effectively to mitigate risks associated with malware infiltration.
