    Passive vulnerability scanning is the process of monitoring network traffic at the packet layer to determine topology, services and vulnerabilities

Understanding Passive Vulnerability Assessment

Passive Vulnerability Assessment is a highly effective security assessment method that involves non-intrusive observation of network traffic and system behaviors. In contrast to Active Vulnerability Assessment, which intentionally probes systems for vulnerabilities, PVA relies on detecting anomalies, irregular activities, and protocol deviations to identify potential security risks.

Key Features of Passive Vulnerability Assessment:

  • Non-Intrusive Approach: PVA operates without actively probing the systems, ensuring that there is no disruption to normal network operations.
  • Anomaly Detection: By monitoring network traffic and data flows, PVA can quickly identify unusual patterns or behavior that may indicate potential threats.
  • Identification of Misconfigurations: PVA helps in pinpointing misconfigured services, unauthorized applications, and unpatched systems that could pose security risks.

Potential Risks:

Organisations that overlook Passive Vulnerability Assessment expose their digital assets to a range of Potential Risks::

  • Undetected Vulnerabilities: By neglecting PVA, early warning signs of threats and vulnerabilities may go unnoticed, giving cybercriminals an advantage to exploit weaknesses before they are addressed.
  • Unseen Threats: Ignoring PVA can result in overlooking critical threats that could be detected through anomaly detection and network monitoring.
  • Regulatory Non-Compliance: Many regulatory frameworks require continuous monitoring of network systems. Neglecting PVA could lead to non-compliance, leading to severe consequences such as hefty fines and reputational damage.
