Explanation

War dialing (B) is correct because it involves using a modem to automatically dial through a list or range of phone numbers, identifying which lines have modems or fax machines connected - a technique historically used to find vulnerable systems or entry points into networks.

• War driving (A) involves driving around with a laptop or device to detect unsecured Wi-Fi networks - wireless, not telephone-based.
• Warchalking (C) is the practice of drawing symbols in public places to indicate the presence and type of nearby wireless networks - no modem or dialing involved.
• Warkitting (D) combines war driving with router exploitation (hijacking DHCP to redirect traffic) - again wireless-focused, not telephone-based.

Memory tip: Think of "war dialing" - the word "dial" is embedded in it, directly reminding you of dialing telephone numbers with a modem.
