Detecting Modems: Phone Line Penetration Testing

Information about these modems can then be used to attempt external unauthorized access.

Answer: B is incorrect.

In sniffing, a protocol analyzer is used to.

The demon dialing technique automatically tests every phone line in an exchange and tries to locate modems that are attached to the network.

most commonly used technique of all, getting information (like passwords) just by asking for them.

The penetration testing technique that automatically tests every phone line in an exchange and tries to locate modems that are attached to the network is called "demon dialing."

Demon dialing, also known as war dialing, is a technique used by attackers to identify phone lines that are connected to modems in order to gain unauthorized access to a system. It involves the use of a software program that automatically dials a large number of phone numbers, looking for lines that are connected to modems. Once a modem is found, the attacker can try to exploit vulnerabilities in the system to gain access.

Sniffing is a technique used to capture and analyze network traffic in order to gain access to sensitive information such as passwords, usernames, and credit card numbers. It involves the use of software programs that intercept and decode network packets.

Social engineering is a technique used to manipulate people into divulging confidential information or performing actions that could compromise the security of a system. It can take many forms, including phishing emails, pretexting, and baiting.

Dumpster diving is a technique used to search through an organization's garbage or recycling bins for sensitive information that has been discarded. Attackers can use this information to gain access to a system or commit fraud.

In summary, the correct answer to the question is A. Demon dialing.
