access the internal service from outside. The unused and unsafe ports should be closed when they are not in use in case of the attacks through these ports. The blocking service prevents the DNS Spoofing, which is an attack to return an incorrect IP address as the response. Secondly, the firewalls restrict the service that are deemed unsafe from inside to outside. Blocking outbound traffic could limit the attackers’ actions once they are a composition if the network. The service prevents the ARP…

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 on share and select vikram in file sharing in other computer…

Using PC used as a proxy server (Fiddler) between Nissan LEAF app (called NissanConnect EV) and the network, it was discovered that the app use an unprotected HTTP protocol (using GET commands) to access vehicle status. Status includes charge level, plug state and time, autonomy, HVAC activation, a timer, and passed trip information. To succeed, the request requires only a valid VIN number to identify the target vehicle, no user id, no password, no session. Activation of AC even returns a user…

2 DESCRIPTION OF THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data…

about (Donegan, 2012, p. 34). What is very interesting is that there aren’t currently any laws on the federal level that address cyberbullying or bullying in general (“Federal laws,” 2014). The issue of cyberbullying is currently being addressed on the state level in our country. In New York, there are a number of pieces of legislation that have been passed, in an attempt to address cyberbullying. These laws identify which categories a person can be targeted based on to be considered a victim of…

IV Methodology The AES algorithm has 4 phases that execute the process in sequential manner. The encryption process is achieved by processing plain text and key for initial and 9 rounds, Same decryption is takes place but in reverse manner. A 4x4 state is formed in each round and particular length data is introduced in it for encryption process.The 10, 12, 14 rounds are there for 128, 192,256 bits in length respectively. Initially a key expansion process is used to expand the basic 16 byte key…

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…

To begin the implementation process, one should first start by backing up all of the company’s data to an external source. Our team recommends two backups on a set of two large external hard drives. These drives will remain on premises and need to be easily accessible in case any issues arise during the implementation process. We suggest Kingo designates two business days to properly train his staff on the new system. Kingo’s operators will need to begin scheduling around these two days as soon…

That November day in 1863 was undoubtedly filled with many emotions to begin with, but somehow Lincoln managed to bring forth even more from his audience. In particular, the speech was being given on the very ground that the bloody battle of Gettysburg had been fought on just four months earlier. Lincoln had intended on delivering this speech in order to tell the people that this battlefield would be turned into a cemetery for those fallen in battle. But with the civil war still raging on, he…

¥ 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…
