Which of the following are common types of network vulnerabilities?

The identification of unpatched software and weak passwords as common types of network vulnerabilities is significant because these factors create substantial risks within network environments.

Unpatched software refers to software that has not been updated to address known security flaws. Cybercriminals often exploit these vulnerabilities to gain unauthorized access to systems. Organizations that fail to regularly patch their software expose themselves to attacks that could compromise sensitive data or disrupt operations.

Weak passwords represent another critical vulnerability. They can be easily guessed or cracked, allowing attackers to gain access to accounts and systems. Strong password policies are essential as they reduce the likelihood of unauthorized access, making weak passwords a common and persistent vulnerability in many organizations.

In contrast, strong passwords and updated software are best practices aimed at reducing vulnerabilities, while redundant network paths and high bandwidth do not inherently contribute to security weaknesses. Firewalls and intrusion detection systems are protective measures rather than vulnerabilities themselves. Recognizing and addressing common vulnerabilities like unpatched software and weak passwords is key to improving overall network security.
