An e-commerce company detects unusual activities on its site. What is the most effective action for future issue identification?

Implementing intrusion detection systems (IDS) and application firewalls is the most effective action for future issue identification because these technologies are specifically designed to monitor network traffic and application behavior for signs of malicious activities or violations of security policies.

An IDS can analyze incoming and outgoing traffic to detect suspicious activities, such as attempts to exploit vulnerabilities or unauthorized access attempts. This proactive approach allows the e-commerce company to respond quickly to threats before they escalate into more significant issues. Application firewalls can provide additional protection by filtering and monitoring HTTP traffic to and from the application, ensuring that only legitimate requests are processed.

In contrast, increasing website hosting resources might enhance performance during peak traffic but does not directly address security threats. Limiting employee access to the website can be important for reducing insider threats, but it does not help identify external attacks. Switching to a different e-commerce platform may be a solution, but it does not inherently provide better detection of unusual activities unless the new platform has superior security features. Therefore, the combination of IDS and application firewalls remains the best option for ongoing monitoring and future issue identification.
