What Is an Idle Scan and How Does it Work? Historically, the purpose of an Idle Scan was to remain anonymous and forge the IP address of an unfiltered, trustable system. Today, however, these attacks have become much more sophisticated and efficient. These techniques are even more effective if the device is a zombie that has access to extra rights, such as logging into the web and downloading a file. To prevent such attacks, administrators should make sure that their ingress filters and firewalls are working properly. The Idle Scan can detect open and closed ports that are vulnerable to…

A ping sweep is a diagnostic process that identifies "dead" and live hosts on a network. This process is used by networking engineers to discover problems on their network, and can also be used to troubleshoot problems in existing networks. A ping sweep consists of sending an echo request to a specific IP address, which receives a reply containing information on the IP address range. This tool scans IP addresses and sends out ICMP echo requests to determine if a machine is online and running. A live machine will respond to the ping request with an echo. Hackers use ping…

A bit stream is a continuous flow of information in a certain order over a communication channel, usually a wire. A bit stream begins at a source and ends at a destination computer. In general, a bitstream contains information about the source and the destination. In computing, a bitstream is used extensively in the field of e-mail. The recipient computer then receives the bitstream, decodes it, and saves it as a file. A bit stream consists of eight bits per token and is a fundamental component of hardware. It is a great way to store data because it allows you…

If you are unfamiliar with the terms password authentication and logical security, this article will help you understand these concepts. These terms refer to the processes used by networks to verify users' credentials. If you are using social networking sites, you may be familiar with password authentication. This method helps to keep your data secure, but isn't enough. You need two-factor authentication, which requires you to provide a second form of identification. While physical threats can be destructive to your hardware, logical threats can damage your data and software systems. These attacks may even shut down your operating system. For…

A reference monitor is a hardware device that is designed to enforce an access control policy on a network. The concept is simple. It defines the design requirements for a validation mechanism to verify the identity of an individual. These devices are commonly used in access control systems. The concept of a reference monitor is derived from the concept of an electronic ID card. It is a device that is designed to enforce an access control security policy. A reference monitor is very expensive. It is constructed in a factory and tested to ensure it is as accurate as possible.…

A data key is a string representing a variable value. It's commonly used in encryption. It is a way to distinguish encrypted from clear text. In most cases, a data key is only used once. However, there are exceptions. There are cases where a data-key is used many times. Here are some examples. Using a dictionary to store and retrieve data is another common use for a data key. An ad server uses a data key to identify an individual in a database. Unlike a password, a data key is unique to a given advertiser. It can help advertisers find…
