What additional security measure could Valley implement to enhance detection capabilities?

Implementing Network Intrusion Prevention Systems (NIPS) enhances detection capabilities by actively monitoring network traffic for suspicious activities and policy violations. NIPS not only detects potential threats in real-time but also takes immediate action to mitigate them, such as blocking malicious packets or alerting system administrators. This proactive approach makes it an essential component of a comprehensive network security strategy, as it helps in recognizing and addressing threats before they can compromise sensitive data or disrupt operations.

In contrast, other options like Wireless Intrusion Prevention Systems (WIPS) focus specifically on securing wireless networks and may not provide the same level of comprehensive coverage for the entire network. Unified Threat Management (UTM) solutions can integrate various security functions but may not have the specific capabilities or focus on intrusion prevention as a NIPS. A Virtual Private Network (VPN) primarily secures data in transit but does not provide intrusion detection or prevention features, which are crucial for identifying and countering potential security threats. Thus, NIPS is the most suitable choice for enhancing detection capabilities effectively across the network.
