It uses voice communications and then gets sent back to the base station. Data technology is also used on smartphones which allow the user to browse the internet and download files. Landline Phones – Landline phones typically only use voice communications. Some newer landline phones can use what is called a NCID (Network Caller ID) which uses data sent over a TCP connection. SMS/Text Messaging – The SMS (Short Message Service) can be used in a variety of ways.
Originally, the message transmitted to the recipient was the telephone number of the sender basically requesting a call back. Soon after, two way pagers where developed. They allow an interactive system of communication between the sender and receiver. Pagers operate on a data network. VOIP phones- voice over internet protocol is a technology that allows phone calls to be made through the internet.
Homework Chapter 7 1. Enter www.kyocera-wireless.com and view the demos. What is a smart phone? What are its capabilities? How does it differ from a regular cell phone?
Which of the following account lockout policy modifications could you make to ensure that user passwords cannot be intercepted by analyzing captured packets? (D) Disable the Store Passwords Using Reversible Encryption policy 2. Which of the following mechanisms is most often used in firewall rules to allow traffic on to the network? (D) Port numbers 3. Which of the following NTFS features is incompatible with EFS encryption?
Pagers is wireless telecommunications devices that receives and displays numeric or text messages, or announces voice messages. A paging system alerts a pager (or group of pagers) by a transmitting information over an RF channel. VOIP(voice over IP) phones uses Voice over Internet Protocol technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network. Skype/Face times is a voice-over-IP service and instant messaging client. The service allows users to communicate with peers by voice using a microphone, video by using a webcam, and instant messaging
Shared key authentication 18.) Each of the following is a limitation of SSID hiding except: The SSID can be discovered in other management frames sent by the AP. 19.) Which of the following is not a limitation to MAC address filtering? Not all client devices have MAC addresses.
By not relying on a specific algorithm, it allows the suite to be modified in the future to support even more security methods. It operates at the network layer, encrypting IP packets making them confidential so that only the receiving device can accept and read them. In addition, it uses checksums to see if the data packet has been manipulated during transfer. IPsec uses Internet Key Exchange to ensure authentication with usernames, passwords, pre shared keys and digital certificates For IPsec, AES is considered the best form of encryption available. It uses a 128 bit shared secret key to decrypt and encrypt data being sent through the VPN.
On Cisco.com, They describe how college campuses are using Wireless LAN Bridges to connect all their buildings together without the use of expensive wired alternatives. Another use Cisco demonstrated was the ability to set up a temporary network connected back to the main office using the wireless bridge, maybe for a triage camp after a natural disaster. Scenario 2 [pic] Identify the wireless technology being used in this scenario. The technology being used is Bluetooth. This technology is typically used to transfer sound between two devices, although it can be used to transfer data as well.
Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting. In order to prove that the network breach was a terrorist attack the company would need to provide electronic evidence of these types of information warfare. Information warfare is a term often used interchangeably with cyberterrorism but provides a deeper understanding in the shift of how data has become fundamental to society. As governments, companies and people shift to the use of digital information so have the methods used to attack (Gilmer, 2001). In order to combat this aspect of terrorism, the military have adopted computer forensics as part of their defenses (Vacca & Rudolph, 2011).
