specific computer and has a socket that is bound to a specific port number. The server just waits, listening to the socket for a client to make a connection request (Polam, 2014). On the client- side, the client knows the hostname of the machine on which the server is…
1. (5 points) Compare and contrast the three types of addresses used in a network. Application layer – A port is assigned to an application for direct routing of incoming and or outgoing data. Network layer – IP addresses are assigned to each individual computer. The IP addresses can change and are often assigned by the DHCP server. Data link layer – Mac Addresses are used to identify which hardware is the sender and which is the receiver. All hardware items have a MAC address. For example:…
192.168.56.101 and server is 192.168.56.102. Run a UDP application flow at 20 mbps Client Output Run a TCP application flow at 20mbps. Client Output Run the UDP flow while also running UDPEcho2 (Packet size 1024) a) Iteration delay – 1 sec Iperf client output UDPEcho client output b) Iteration delay – 0.1 sec Iperf client output UDPEcho client output c) Iteration delay – 0.01 sec Iperf client output UDPEcho client output d) Iteration delay – 0.001 sec Iperf…
Answer 3:- A:- When it is very expensive and slow to access the external network then we use Forwarding name server . What is does keep the records of frequently visited sites in local DNS cache. This improves the efficiency . B:- Round Robin mechanism is used for load balancing . DNS hold maximum record of entry. In round and robin mechanism it allocate IP address to the requested client as per the availability and making the server highly available . Answer 4:- "in.addr-arpa" is used to…
action. Worm takes advantage of any information transportation system such as file. It has the capability to replicate itself on a computer, instead of sending out a single worm, it could send hundreds of copies of itself. It has the capability to travel across networks and consumes too much of system memory causing servers and networks to stop responding. Blaster worm: This worm mainly targets Microsoft platforms in the year 2003.This worm attacked computers by exploiting remote procedure…
Such behavior frequently includes things like gaining control of a computer system, allowing privilege escalation, or a denial-of-service attack. It is run on web servers, with the purpose of identifying software susceptibilities in client machines, communicating with it and exploiting discovered vulnerabilities to upload and execute malicious code on the client. 3 e. How many options are there? How many of these are required? As seen in snapshot, show command gave 2 options. RHOST and RPORT.…
The transport layer encapsulates the application data with data unit. The transport layer protocol creates a virtual flow of data sent and received between the sending applications, divided by the transport port number. The port number identifies a port, a place dedicated to the memory to receive or send data presentation. The services layer protocol transport reliable delivery of the order data. The final result depends on TCP, SCTP, vs UDP handles the…
1.10 FIREWELL: Firewall is a physical security device that cleaned in specs traffic coming from one network to a different network. A firewall is a system that implements an access control policy among two networks. Example: “Allows: http, mails etc. Keeps out: intruders, denial of services attacks etc.” 1.10.1 Firewall work: The protocol that computers use to be in touch on the internet is called TCP/IP. Each computer on the Internet has a only one of its kind internet protocol and…
The purposed network architecture will consist of four deployable tough boxed server stack’s which will contain two Dell 1130 1U Rugged Dart Frogs server blades sporting two Intel Xeon E5645 Processors that has 12M Cache, 2.40 GHZ operation speed. Each blade has “96 Gigabyte of DDR3 Memory operating at 1333MHz LV, two 40 Gigabyte 2.5 Serial ATA II Solid State Drives, ten Network Interface cards (NICs), an Intel Gigabit Quad Port Ethernet adapter, using a LSI 3081E-R add-in RAID controller”…
application. The lab portrayed the flow information traffic as movement through a series of ports, similar to entering doors of houses owned by other people. If this flow is manipulated, there can be vulnerabilities for unauthorised entries, bringing in malware or other harmful or unwanted data. Method: Within the lab, we employed the command prompt to discover connection…
