As you can see, the ARP is very simple. Yet, despite its simplicity, it has a few profound advantages. First, ARP is dynamic in nature, which obviates the need to statically track and store IP to physical addresses. This dynamic resolution behavior frees the network manager from constantly maintaini[r]

Recall from Chapter 4, "TCP and UDP," that there is an initial handshake process that must take place between hosts before a TCP conversation can occur. It is during this phase that the attacker would have to guess the initial sequence number sent in reply to the SYN request from[r]

27.6 TCPAP Standards For Electronic Mail Service
Recall that the goal of the TCP/IP protocol effort is to provide for interoperability across the widest range of computer systems and networks. To extend the interoperabil- ity of electronic mail, TCP/IP divides its mail stand[r]

that SNMPv1 had only rudimentary password and authentication features and even lacked a good encryption technique.
The greatest threat that network management poses to a network, ironically, comes from exploiting remote confi guration capabilities, one of the most useful things in networ[r]

• Determining the class of the address by looking at the first 4 bits of the IP address:
– Class A begin with 0xxx , or 1 to 126 decimal
– Class B begin with 10xx , or 128 to 191 decimal
– Class C begin with 110x , or 192 to 223 decimal

 Sự có mặt của GFA tạo ra một sự phân cấp trong việc quản lý di động. Trong đó, Mobile IP là giao thức quản lý tính động (macro-mobility) trong mạng dịch vụ. Nó được sử dụng để xử lý tính động ở lớp IP, giữa hai mạng truy nhập (có thể là hữu tuyến[r]

2. Multicast security
The original conception of an IP network was aimed at the exchange of information between two nodes. However, very soon the popularity of the Internet gave rise to a number of applications for which a better model would be desirable. Such applications would bene ſ t fr[r]

 These protocols cannot be used as they were stated.
 In implementation of the actual protocol, there are many situations one should be careful of.
 In this lecture, we will look at some common protocol failures that arise when trying to implement security protocols
