There are several common network vulnerabilities, including but not limited to:  Physical Vulnerabilities: Lack of strong infrastructure around servers can give access to data to any perpetrators.  Software vulnerabilities: Outdated software or getting software from unauthorized vendors makes your system vulnerable to attack.  Configuration vulnerabilities: Misconfigured devices create an entry point for intruders.  Human-based vulnerabilities: Untrained and unsuspecting employees often fall for phishing and other social engineering attacks to compromise an organization’s data. They are also one of the most common network vulnerabilities.  IoT Vulnerabilities: IoT devices are often poorly configured with weak encryptions leading to cyber-attacks.
