Some of the things that NCP does include file access, printer access, security. Using TCP/IP (transfer control protocol) which is also on layer three and four of the model, and it allows a network to communicate through ort 80 or also known as HTTP (Hypertext Transfer Protocol. These protocols would be chosen based on the security, and the devices it needs to access the internet. In anything to do with networks and computers security is always number one so putting a WPA2 enterprise with a wireless router, in place would be very beneficial for Kudler so the router and the network can have a passcode in place so there will be no outside influences to hack the system. The authentication of the Radius server will be used for the WPA Enterprise which the router uses is 802.
An analysis of the network systems in use The current network system that Patton-Fuller is using is a network that is One GB, using Cat 6 and single Mode Fiber which gives greater speeds and trusted reliability. The technologies that are in place also have an intelligence built into them that alerts the network operations center when any malicious intend to the system is being done. The network also has a build in redundancy to prevent collision. Patton-Fuller has been using a CISCO System 7609 Router and a CISCO Systems ASA 5510 VPN (Virtual Private Network) Router. This helps with secure VPN and Internet traffic through the ASA 5510 VPN Router.
I would implement firewalls, cryptography, antispyware, antivirus, and content filtering. These will be installed in various levels of our network infrastructure including, our mail servers, gateways, laptops and desktops. When these security technologies are in place a threat may be able to bypass on level of security but will be detected and eradicated at another. Layering our security in this manner will mitigate the risks of an employee disabling their protection on the workstations. Our mail servers which send, receive and store emails must be secured as well.
This link is above the Physical layer it is responsible for end-to-end validity of what is being transmitted. Datalink layer is divided into; two sub-layer which is Media Access Control (MAC) that determines the physical addressing of the host. The MAC addresses (physical device addresses) that communicate with other devices within the network. Then there is the Logical Link Control (LLC) sub layer. What it is responsible for is the synchronizing frames, error checking, and the flow control.
Computers are related to networks due to the fact that computers need to be able to communicate to one another on the same network. Computers come in different sizes and processing levels. Computers are needed in any wireless network. Price varies from $299.99 to $4,999.99 Tiger Direct (n.d.) A firewall is considered a device that connects or is built in the software and directly to a network or computer with Windows XP and higher operating systems. A firewall used security purpose that only allows trusted sources to access the network or the other way around.
2. Which of the following standalone devices can be found near the Internet edge, with a primary purpose of providing some type of network security between an enterprise or SOHO TCP/IP network and the Internet? (Choose two answers.) a. LAN access point b. IPS c. Analog modem d. Firewall Answer: B, D. A firewall normally sits inline, in the packet-forwarding path, choosing which packets to allow and disallow. An intrusion prevention system (IPS) can sit inline or outside the packet-forwarding path, reporting on complex attacks based on combinations of events.
By proper end user training for anyone involved with the Corporate Techs site, proper scanning of all USB and thumb drives on a test computer being used for this particular site, can mitigate threats from bugs and viruses. Also, by changing all local computer default autorun policies, will disable usage of these USB ports and stop an occurrence from taking place. Last, it’s almost near impossible for an end user to not use a personal laptop during work hours for personal use or for work. But to mitigate further problems from happening, I will implement an encrypted file system for sensitive data. TrueCrypt is a program that I have found efficient that controls over endpoints that enter and exit the internal system.
The first recommended piece of equipment is a strong firewall, in this case the Dell SonicWall NSA 4600 (SonicWall). The firewall will manage multiple tasks for both offices including being the DHCP server, the DNS server, preventing outside intrusion, managing the wireless access points (WAPs), controlling the connection to the New York office and authenticating remote users. Each of these tasks can be handled by the recommended firewall (Dell). The firewall specified in Table 1 of Section 1.5 is also includes five technician licenses for Dell Virtual Assistant, a program used for remote assistance of users. The device also includes 3 years anti-virus and anti-SPAM protection for all devices connected to the network (Dell).
Question 15 The Wide Area Network (WAN) design below represents what type of fault-tolerant network design? Question 16 Which QoS design consideration is incorrect? Question 17 Which term is best described by the following definition: “Both NICs are active at the same time, and they each have their own MAC address”? Question 18 Which of the following is one of the two modes of Network Interface Card (NIC) redundancy? (Choose 2) Question 19 The ________ command can be used to display information about current sessions, including source and destination IP addresses and port numbers.
This layer connects internet protocol to underlying network protocols in the physical layer. 5. What are the call management functions that VoIP must perform VoIP must perform similar call management functions, including the following: • Establishing connections between VoIP end nodes on IP networks • Establishing connections between VoIP end nodes and PSTN and other phones • Performing protocol conversions as needed • Managing available network capacity to ensure quality of service 6. What does a programming language standard define? A programming language standard defines the following: • Language syntax and grammar • Machine behavior for each instruction or statement • Test programs with expected warnings, errors, and execution behavior 7.
