What is a security token?A security token is a physical or digital device that provides two-factor authentication (2FA) for a user to prove their identity in a login process. It is typically used as a form of identification for physical access or as a method of computer system access. The token can be an item or a card that displays or contains security information about a user and can be verified by the system. Show
Security tokens can be used in place of, or in addition to, traditional passwords. They are most commonly used to access computer networks but also can secure physical access to buildings and act as electronic signatures for documents. Security tokens can serve a vital role in two-factor authentication.How do security tokens work?A security token provides authentication for accessing a system through any device that generates a password. This can include a smart card, a Universal Serial Bus key, a mobile device or a radio frequency identification card. The device generates a new password every time it is used, so a security token can be used to log in to a computer or virtual private network by typing the password generated by the token into the prompt. Security token technology is based on the use of a device that generates a random number, encrypts it and sends it to a server with user authentication information. The server then sends back an encrypted response that can only be decrypted by the device. The device is reused for every authentication, so the server does not have to store any username or password information, with the intent of making the system less vulnerable to hacking. Types of security tokensMultiple types of security tokens are used to secure a variety of assets and applications. These include the following:
Security token advantagesWhile it's true that passwords and user IDs are still the most widely used form of authentication, security tokens are a more secure option for protecting networks and digital systems. The trouble with passwords and user IDs is that they are not always secure. Threat actors continue to refine methods and tools for password cracking, making passwords vulnerable. Password data may also be accessed or stolen in a data breach. In addition, passwords are often easy to guess, usually because they are based on easily discoverable personal information. Security tokens, on the other hand, use a physical or digital identifier unique to the user. Most forms are relatively easy to use and convenient. Security token vulnerabilitiesWhile security tokens offer a variety of advantages to users and organizations, they can introduce disadvantages as well. The main disadvantage of physical security tokens is that they are subject to loss and theft. For example, a security token could be lost while traveling or stolen by an unauthorized party. If a security token is lost or stolen, it must be deactivated and replaced. In the meantime, an unauthorized user in possession of the token may be able to access privileged information and systems.

Which two tools used for incident detection can be used to detect anomalous behavior to detect command and control traffic and to detect infected hosts?Explanation: Although each of these tools is useful for securing networks and detecting vulnerabilities, only an IDS and NetFlow logging can be used to detect anomalous behavior, command and control traffic, and infected hosts.
