What are the disadvantages of using symmetric encryption over asymmetric encryption?

1.Inability to support non-repudiation: Since both the sender and receiver use the same key, it is difficult to determine who is the sender, should a dispute arise.2.Impractical for web commerce: Imagine thousands of customers buying goods and services over the Internet. If symmetric encryption standard is used, one unique private key-pair needs to be used for each user. It is therefore, impractical.3.Another major difficult is with the transmission of private key. With symmetric encryption, the private key needs to be transmitted to the other party for decryption, which may pose security risk.

Asymmetric keys use how many keys?

2 keys creates digital signatures, PUBLIC KEY CRYPTO!RSA, DIFFIE-HELLMAN and ECC.

What are the steps involved with CHAP?

CHAP (Challenge Handshake Authentication Protocol) works on point to point connections. It uses a three step process for authentication (excluding making the connection itself). If making the connection is also involved, it would be a 4 step process.

TPM does what?

It stores and generates CRYPTO keys.

What are MAC�s?

Message Authentication Codes (MACs), also called "keyed hashes", are used to verify the authenticity of a message. Let us say, Jane (the sender of a message) and Mike (the recipient) share a secret key. Jane uses the message and the key to compute the MAC, and sends the MAC along with the message. When Mike receives the message, he computes the MAC, and then checks to see if his MAC matches Jane�s. If it does, then he knows the message is from Jane and that nobody has changed it since she sent it

What are hashing algorithms and what are they used for?

Hashing is a ONE-WAY hash, creates a UNIQUE signature for a set of DATA. Hashing is used for integrity.Hash Algorithms: Hash algorithms produce a hash of a message and encrypt it. They use a mathematical formula for hashing, and it is extremely difficult to tamper with the message and still produce the same hash. Basically, Hashing enable a recipient to check whether a message is received intact without being tampered by a third party.

What is the MAC?

Mandatory Access Control (MAC) secures information by assigning sensitivity labels on objects (resources) and comparing this to the level of sensitivity a subject (user) is operating at. MAC ensures that all users only have access to that data for which they have matching or greater security label (or security clearance). In general, MAC access control mechanisms are more secure than DAC. MAC is usually appropriate for extremely secure systems including multilevel secure military applications or mission critical data applications.

What is RoAC? Real-world approach...

Role Based Access Control (RBAC): In Role-Based Access Control (RBAC), access decisions are based on an individual's roles and responsibilities within the organization. For instance, in a corporation, the different roles of users may include those such as chief executive, manager, executive, and clerk. Obviously, these members require different levels of access in order to perform their functions, but also the types of web transactions and their allowed context vary greatly depending on the security policy. In Role Based Access Control, the administrator sets the roles. Therefore, this type of access control is sometimes considered as a subset of MAC.

What is DAC?

Discretionary Access Control (DAC): Discretionary Access Control (DAC) is a means of restricting access to information based on the identity of users and/or membership in certain groups. Access decisions are typically based on the authorizations granted to a user based on the credentials he presented at the time of authentication (user name, password, hardware/software token, etc.). In most typical DAC models, the owner of information or any resource is able to change its permissions at his discretion. DAC has the drawback of the administrators not being able to centrally manage these permissions on files/information stored on the web server.


Rule Based Access Control (RBAC): The access to a resource in Rule Based Access Control is based a set of rules. ACLs (Access Control Lists) are used for this type of access control. In Rule Based Access Control, the administrator sets the rules. Therefore, this type of access control is sometimes considered as a subset of MAC.

What is FSRM?

Because port numbers are 32 bits in length they can have a decimal value from 0 to 65,535. 16/16True False

trueTCP uses the notion of port numbers to identify sending and receiving application end-points on a host, or Internet sockets. Each side of a TCP connection has an associated 16-bit unsigned port number (0-65535) reserved by the sending or receiving application. Arriving TCP data packets are identified as belonging to a specific TCP connection by its sockets, that is, the combination of source host address, source port, destination host address, and destination port. This means that a server computer can provide several clients with several services simultaneously, as long as a client takes care of initiating any simultaneous connections to one destination port from different source ports.Port numbers are categorized into three basic categories: well-known, registered, and dynamic/private. The well-known ports are assigned by the Internet Assigned Numbers Authority (IANA) and are typically used by system-level or root processes. Well-known applications running as servers and passively listening for connections typically use these ports. Some examples include: FTP (21), SSH (22), TELNET (23), SMTP(25) and HTTP (80). Registered ports are typically used by end user applications as ephemeral source ports when contacting servers, but they can also identify named services that have been registered by a third party. Dynamic/private ports can also be used by end user applications, but are less commonly so. Dynamic/private ports do not contain any meaning outside of any particular TCP connection.
