Malvertising: A hacker injects malicious or malware-laden advertisements into legitimate online advertising networks and web pages. Defenses Here are some of the security techniques and procedures that can be put into place to mitigate social engineering attacks: ■ Password management: Guidelines such as the number and type of characters that each password must include and how often a password must be changed. ■ Two-factor authentication: Combining something the user has and something the user knows to authenticate their access to the network.
A message authentication code is produced by passing the message data along with the secret key through a hash algorithm. Only the sender and the receiver know the secret key, and the output of the hash function now depends on the message data and the secret key. Figure 29-2 illustrates how the message authentication code is created. Data of an arbitrary length is input into the hash function, together with a secret key. The result is the fixed-length hash that depends on the data and the secret key.
Vice versa, data that is encrypted with the public key requires the private key to decrypt. Asymmetric encryption is also known as public key encryption. Here is one possible scenario of asymmetric encryption in action. In Figure 29-5, imagine that Bob has generated a public/private key pair. Bob keeps the private key totally secret but publishes the public key so it is available to everyone. Alice has a message that she wants to send to Bob in private. If Alice encrypts the message using Bob’s public key, only Bob has the private key that is required to decrypt the message, providing confidentiality.
