War dialing is a very old attack and depicted in movies that were made years ago.
Why would a modem security tester consider using such an old technique?

  1. It is cool, and if it works in the movies it must work in real life.
  2. It allows circumvention of protection mechanisms by being on the internal network.
  3. It allows circumvention of the company PBX.
  4. A good security tester would not use such a derelict technique.

Answer(s): B

Explanation:

If you are lucky and find a modem that answers and is connected to the target network, it usually is less protected (as only employees are supposed to know of its existence) and once connected you don’t need to take evasive actions towards any firewalls or IDS.



Which of the following act in the united states specifically criminalizes the transmission of unsolicited commercial e-mail(SPAM) without an existing business relationship.

  1. 2004 CANSPAM Act
  2. 2003 SPAM Preventing Act
  3. 2005 US-SPAM 1030 Act
  4. 1990 Computer Misuse Act

Answer(s): A

Explanation:

The CAN-SPAM Act of 2003 (Controlling the Assault of Non-Solicited Pornography and Marketing Act) establishes requirements for those who send commercial email, spells out penalties for spammers and companies whose products are advertised in spam if they violate the law, and gives consumers the right to ask emailers to stop spamming them. The law, which became effective January 1, 2004, covers email whose primary purpose is advertising or promoting a commercial product or service, including content on a Web site. A "transactional or relationship message" – email that facilitates an agreed-upon transaction or updates a customer in an existing business relationship – may not contain false or misleading routing information, but otherwise is exempt from most provisions of the CAN-SPAM Act.
