Trendnet advertises itself as an Ethernet based device manufacturer, but also boasts a large collection of wireless devices as well. Trendnet routers often include dual antennas for maximum coverage, four Ethernet ports, and advanced WPA encryption. Trendnet devices tend to be small, lightweight, and stylish, allowing users to set them up and forget about them. …
In cryptography, the known plaintext attack, or KPA, is an attack based on having samples of both the plaintext and corresponding encrypted or ciphertext for that information available. This information is used to conduct an analysis of the data in order to determine the secret key used to encrypt and decrypt the information. Historical ciphers …
LSASS, or local security authority subsystem service, is a process that functions as part of the Microsoft Windows operating system. Essentially, LSASS is part of the process for maintaining and enforcing the security protocols on the operating system. To this end, LSASS performs several important functions to ensure that the system remains free from unauthorized …
Tor is a program that is able to hide the user’s online activities from third parties and prevent websites from seeing where the user is browsing from by rerouting the user’s sent and recieved data through the Tor Network. The Tor Network is made up of hundreds of volunteers from around the world that specifically …
Computer worms are programs that reproduce, execute independently, and travel across network connections. The key difference between a virus and worm is the manner in which each reproduces and spreads. A virus is dependent upon the host file or boot sector and the transfer of files between computers to spread, whereas a computer worm can …
The two most common types of encryption algorithm used in modern cryptography are the block and stream ciphers. The block cipher uses a deterministic algorithm that conducts operations on fixed-length groupings of bits, or blocks. By using a transformation specified by a symmetric key, a block cipher is able to encrypt bulk data, and is …
Virtually every computer in the world has some form of adult pornography stored somewhere on its hard drive. This can be due to personal use, viruses, or the fact that pornography seems to be included with every downloaded file, opened webpage, and email attachment. Pornography can also be a concern when many people have access …
There are various scenarios in which a password needs to be used. A feature that goes hand-in-hand with password use is the ability to change or reset it. The need to change a password arises predominantly for two reasons: 1) as a means of maintaining high security by regularly changing the password so that unauthorized …
“Physical access to a computer or router usually gives a sophisticated user complete control over the device. Software security measures can often be circumvented when access to the hardware is not controlled.” — Cisco Systems, Inc. Recovering the passwords for most Cisco devices via the console port is very simple. However, Cisco has purchased so …
GPG, or GNU Privacy Guard, is a free replacement and competing product for PGP (Pretty Good Privacy). The project is a data encryption and decryption application which provides end-users with a cryptographic privacy and authentication system for communicating electronic data. GPG can be used to sign, encrypt, and decrypt text, for email, files, directories, and …
