System security comprises of the procurements and approaches embraced by a system overseer to counteract and screen unapproved access, abuse, alteration, or refusal of a PC system and system available assets. To comprehend what is system security, it serves to comprehend that no single arrangement shields you from a mixture of dangers. You require various layers of security. On the off chance that one comes up short, despite everything others stand. System security is proficient through…

Protect Yourself from Social Networking Nicola Formichetti once said, “ The dark side of social media is that, Within seconds, anything can be blown out of proportion and taken out of context. And it’s Very difficult not get swept up in it all”. In Social media thing get swept out of proportion so we need to protect ourself from this from happening. In the article “ The Dangers of Social Networking” by Robin Olsen Suggest ways on how to protect yourself from social networking. Robin Olsen is…

A traditional traffic model for circuit switched data as well as packet data is the Poisson process in which the number of incoming packets per time is according to Poisson distribution. It is one of the most widely used and oldest traffic models. In this model the length of each packet is based on exponential distribution and the number of simultaneously ongoing packets is according to Erlang distribution [16]. The Poisson process is characterized as a renewal process. In a Poisson process the…

In the paper, [1], the author introduced two kinds of topology attacks focus on the architecture of SDN and emphasized the weakness of the host tracking service and the link discovery service. And then, the paper provides the security extension, called Topoguard, for the Floodlight v0.9 controller. A. Two topology attacks The first attack as we mentioned, Host Location Hijacking Attack, is to send a fake request that the target host migrates to a new location trying to intercept packets and…

the help of splitter. For instance, A 1:8 splitting ratio will have : a. Number of users: 8 b. Power: 12.50 c. Insertion Loss : -9 Activity 3 To analyze the OLT Unit we were supposed to use putty.exe for the serial console using Telnet as a protocol and U2000 Client as a graphical user interface (GUI). 1. To go to the user mode first we need to login as the following step : • Username: user04 • Password: user1234 • The User Mode • To enter the privilege mode from user mode type…

Inspite of its conceptual elegance, RPC (Remote Procedure Call) have a few problems. Discuss any 3 of those in brief. Often times it is unclear who the client is and who the server is in certain situations, in these types of situations RPC would not be suitable. RPC also makes unexpected messages hard or impossible to send if the receiver of the message is not expecting the message. Also RPC does not allow multi-threaded servers even when one would be appropriate(Tanenbaum & Renesse, n.d.).…

Unit Standard 26227 (ER 4.1, 4.2, 4.3) Outcome 4: Customize the LAN’s user interface. a) Map network drive for user A) First we open active directory users and computer B)then open users and create new user C)then open up new user’s properties which we created D) then go to security and allow full control E) after that open advance option and click on check names and select your name F) after that select the new user which is created G) then click on “OK” and select click…

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 remove the obstruction to subnet on non-octet boundaries. Thus making it possible to assign IP address in smaller octet then 24 bit prefix without losing the ability to delegate authority for in.addr-arpa mapping. In…

¥ 1. An IP address is an identifier for devices on a TCP/IP network. Usually, an IP address could be assigned using a 32-bit numeric address written as four numbers separated by periods. Each number can go from being zero to 255. For example, 1.160.10.240 could be an IP address. Although IP address can be static or dynamic. A static IP address stays the same and it is a permanent Internet address. On the other hand, a dynamic IP address is a temporary address that is assigned each time a…

These factors has led to a rapid decline in available addresses for IPv4. Several methods were implemented in order save the remaining addresses. One of them included the use of Network Address Translation. NAT provides a method of allowing several addresses to be connected to the internet through a public IP address. There are many problems associated with NAT which is not prevalent in IPv6. This has seen a drastic improvement in performance by using…
