A common argument used to justify the absence of explicit bounds on the length of input ccepted is that safe languages such as Java do not carry the inherent buffer over ow risks that C and C++ do This is a partial truth Because Java Web applications frequently act as front ends to legacy systems or call into native code libraries using JNI, even though unbounded input might not directly lead to a vulnerability in Java code, it can easily lead to an exploit in an area of the system implemented in another language Missing bounds checks in a Java application can make it an ideal transmitter for a buffer over ow payload. string str; cin >> str; Make Code39 In Visual Studio .NET Using Barcode maker for .

Cryptographic systems based on the use of keys can be thought of as analogous to combination locks They involve both an algorithm and a secret value The secret value is the key (analogous to the number that opens the combination lock) and this must be protected from adversaries The cryptographic algorithm can be considered to be analogous to the working of the combination lock The design of the algorithm is expected to be known widely In fact, making the design of the algorithm public can lead to analysis of its weaknesses by the community The security of the system should only depend on the secrecy of the key, and an adversary who desires to break the cryptographic system has to determine the key used to secure communications A basic approach that can be taken by the adversary is to try every key and see which breaks the system based on some information about the system For example, if packets between two nodes are encrypted, then the adversary might have an idea as to the protocol being used, such as TCP or UDP By trying every possible key to decrypt the packets, the adversary will come up with random strings Only a few such strings will t the format associated with a packet belonging to the protocol More information about the data, such as the identity of the parties communicating or the port numbers being used for the communication, could be used to increase the probability of determining the right key being used Such an approach is easy to pursue in wireless systems given the susceptibility of wireless links to eavesdropping, making all traf c going over the network available to the adversaries It is obvious that the effort required for such an attack to be successful is proportional to the length of the key An 8 bit key length implies that there are 28 different keys possible while an 80 bit key length implies that there are 280 different keys possible This is similar to the case of combination locks Even here, longer combinations of keys take longer to break as opposed to smaller combinations, assuming that all possible keys can be tried However, we cannot conclude that longer key length always translates nto better security for the system In some cases, there can be other vulnerabilities in the system, including the encryption algorithm, that the adversary could take advantage of For example, it has been shown that the security of WEP (the typical protocol used for securing 80211b) can be broken irrespective of the size of the key used [8] Hence, while key size is important, the evaluation of cryptographic primitives cannot be done solely based on the size of the keys Other factors which are used to evaluate the various cryptographic primitives include:.

This means, the attributes also provide the opportunity to extend the functionality of RADIUS erver to interact with many other entities and for many purposes. Also to support implementation-specific scenarios, vendor-specific attributes (VSA) can be defined, so that each vendor s NAS and RADIUS server can interact in a manner that is specific to the implementation defined by the vendor. RADIUS base specification [RADIUS2865] specifies around 40 attributes, while several other attributes are defined by later RFCs, some of which are mentioned in later sections of this text. The list of attributes is rather extensive, so, we will refrain from providing a comprehensive list here. For such lists, the reader is referred to the IETF specifications, specifically [RADIUS2865]. These lists typically also include the capability of each RADIUS messages to carry the attribute. Table 6.3 shows some examples. The IETF RADIUS extension working group [RADEXTWEB] is working actively on defining new attributes that extend RADIUS functionality in a way that preserves backward compatibility with the existing RADIUS deployments. Unfortunately due to the limited number of bits (8) in the type field of the attributes, the attribute space is limited to only 255 allowed attributes. This and the need for backward compatibility for the large RADIUS deployment base have caused the IETF RADIUS community to guard the attribute space tightly and strictly question any suggestions for standardization of new attributes. For more discussion, see the RADIUS issues section. It is also theoretically possible to extend RADIUS functionality by creating new RADIUS messages. However, to preserve backward compatibility, the group is refraining from doing so.

Secure e-mail in Java Make Quick Response Code in ava Secure e-mail. Mail. Draw Barcode In Java Using Barcode encoder for .In previous sections of this chapter, we have examined fundamental issues in network security, including symmetric key and public key encryption, authentication, key distribution, message integrity and digital signatures In this section and the following two sections, we'll next examine how these techniques are being used to provide security in the Internet Being consistent with the general structure of this book, we begin at the top of the protocol stack and discuss application-layer security Our approach here is use a specific application, namely, e-mail, as a case study for application-layer security We then move down the protocol stack In Section 77 we examine the SSL protocol, which provides security at the transport layer for TCP And in Section 78, we'll consider IPsec, which provides security at the network layer Interestingly, it is possible to provide security services in any of the top four layers of the Internet protocol stack [Molva 1999] When security is provided for a specific application-layer protocol, then the application using the protocol will enjoy one or more security services, such as secrecy, authentication or integrity When security is provided for a transport-layer protocol, then all applications that use that protocol enjoy the security services of the transport protocol When security is provided at the network layer on a host-to-host basis, then all transport layer segments (and hence all application-layer data) enjoy the security services of the network layer When security is provided on a link basis, then all IP datagrams traveling over the link receive security services of the link One might wonder why security functionality is being rovided at multiple layers in the Internet Wouldn't it suffice to simply provide the security functionality at the network layer, and be done with it There are two answers to this question First, although security at the network layer can offer "blanket coverage" by encrypting all the data in the datagrams (ie, all the transport-layer segments) and by authenticating all source IP addresses, it can't provide userlevel security For example, a commerce site can not rely on IP-layer security to authenticate a customer who is purchasing goods at the commerce site Thus, there is a need for security functionality at higher layers as well as blanket coverage at lower layers Second, in the Internet it is generally easier to deploy new services, including security services, at the higher-layers of the protocol stack While waiting for security to be broadly deployed at the network layer (which is arguably still many years in the future) many application developers "just do it" and introduce security functionality into to their favorite applications A classic example is PGP, which provides for encryption of email (and will be discussed later in this section) Requiring only client and server application code, PGP was one the first security technologies to be broadly used in the Internet Similarly, transport-layer security with SSL was broadly introduced into the Internet, as it too only required new code in the end systems However, IP-layer security -- socalled IPsec -- is taking much longer to broadly deploy, as it requires significant changes in the routers in the network core.

We don t know whether the given le is compressed In either case we begin by opening the le in read binary mode, and then we read the rst two bytes If these bytes are the same as the gzip magic number we close the le and create a new le object using the gzipopen() function And if the le is not compressed we use the le object returned by open(), calling its seek() method to restore the le pointer to the beginning so that the next read (made inside the pickleload() function) will be from the start We can t assign to self since that would wipe out the IncidentCollection object that is in use, so instead we clear all the incidents to make the dictionary mpty and then use dictupdate() to populate the dictionary with all the incidents from the IncidentCollection dictionary loaded from the pickle Note that it does not matter whether the processor s byte ordering is big- or little-endian, because for the magic number we read individual bytes, and for the data the pickle module handles endianness for us. Using Barcode encoder for .NET framework Control to generate create EAN128 image in .NET applications.We have used four bytes for the magic number and two for the version Endianness is not an issue because these will be written as individual bytes, not as the byte representations of integers, so they will always be the same on any processor architecture To write and read raw binary data we must have some means of converting Python objects to and from suitable binary representations Most of the functionality we need is provided by the struct module, brie y described in the sidebar The Struct Module ( 297), and by the bytes and bytearray data types, brie y described in the sidebar The Bytes and Bytearray Data Types (293 ) The bytes and bytearray classes methods are listed in Tables 71 ( 299) and 72 ( 300) Unfortunately, the struct module can handle strings only of a speci ed length, and we eed variable length strings for the report and aircraft IDs, as well as for the airport, the aircraft type, and the narrative texts To meet this need we have created a function, pack_string(), which takes a string and returns a bytes object which contains two components: The rst is an integer length count, and the second is a sequence of length count UTF-8 encoded bytes representing the string s text Since the only place the pack_string() function is needed is inside the export_binary() function, we have put the de nition of pack_string() inside the export_binary() function This means that pack_string() is not visible outside the export_binary() function, and makes clear that it is just a local helper function Here is the start of the export_binary() function, and the complete nested pack_string() function:.

The type of service field requests that a specific level of service be offered to the datagram Some applications may require quick responses to reduce network delays, greater reliability, or higher throughput The total length field states the total length of the datagram (including both header and data) A maximum value of 65,536 bytes is usually imposed, but many networks may only support smaller sizes All networks are guaranteed to support a minimum of 576 bytes The identification field allows datagrams that are part of a sequence to be uniquely identified This field can be thought of as a sequence number, allowing ordering of datagrams that arrive out of sequence Sometimes when packets are sent between network gateways, one gate-way will support only smaller packets The flags field controls whether these datagrams may be fragmented (sent as smaller pieces and later reassembled) Fields marked "do not fragment" are discarded and are undeliverable As datagrams are routed across the Internet, congestion throughout the network or faults in intermediate gateways may cause a datagram to be routed through long and winding paths So that datagrams don't get caught in infinite loops and congest the network even further, the time-to-live counter (TTL) field is included The value of this field is decremented every time it is routed by a gateway, and when it reaches zero the datagram is discarded It can be thought of as a self-destruct mechanism to prevent network overload The protocol type field identifies the transport level protocol that is using a datagram for information transmission Higher-level transport protocols rely on IP for sending messages across a network Each transport protocol has a unique protocol number, defined in RFC 790 For example, if TCP is used, the protocol field will have a value of 6 To safeguard against incorrect transmission of a datagram, a header checksum is used to detect whether data has been scrambled If any of the bits within the header have been modified in transit, the checksum is designed to detect this, and the datagram is discarded Not only can datagrams become lost if their TTL reaches zero, they can also fail to reach their destination if an error occurs in transmission The next two fields contain addressing information The source IP address field and destination IP address fields are stored as two separate 32-bit values Note that there is no authentication mechanism to prove that a datagram originated from the specified source address Though not common, it is possible to use the technique of "IP spoofing" to make it appear that a datagram originated from a specific address, such as a trusted host The final field within the datagram header is an optional field that is not always present The datagram options field is of variable length, and contains flags to control security settings, routing information, and time stamping of individual datagrams The length of the ptions field must be a multiple of 32 if not, extra bits are added as padding IP Address The addressing of IP datagrams is an important issue, as applications require a way to deliver packets to specific machines and to identify the sender Each host machine under the Internet Protocol has a unique address, the IP address The IP address is a four-byte (32-bit) address, which is usually expressed in dotted decimal format (eg, 19216806) Although a physical address will normally be issued to a machine, once outside the local network in which it resides, the physical address is not very useful Even if somehow every machine could be located by its physical address, if the address changed for any.While ICMP is a useful protocol to be aware of, only a few network applications will make use of it, as its functionality is limited to diagnostic and error notification One of the most well known applications that use ICMP is the ping network application, used to determine if a host is active and what the delay is between sending a packet and receiving a response NOTE Java does not support ICMP access, so ping applications are impossible to write in Java Some Java textbooks include a UDP example called ping, but it is important to remember that this is not the real ping application The only way to write a true ping application in Java would be to use the Java Native Interface (JNI) to access native code; such a discussion is beyond the scope of this book 1513 Transmission Control Protocol The Transmission Control Protocol (TCP) is a Layer 4 protocol (transport layer) that provides guaranteed delivery and ordering of bytes TCP uses the Internet Protocol to send TCP segments, which contain additional information that allows it to order packets and resend them if they go astray TCP also adds an extra layer of abstraction, by using a communications port A communications port is a numerical value (usually in the range 0 65,535) that can be used to distinguish one application or service from another An IP address can be thought of as the location of a block of apartments, and the port as the apartment number One host machine can have many applications connected to one or more ports An application could connect to a Web server running on a particular host, and also to an e-mail server to check for new mail Ports make all of his possible.
