Carriage Return and Line Feed (CRLF) are special character elements typically embedded in Hypertext Transfer Protocol (HTTP) headers and some other software code. The inclusion of these character elements is to denote an End of Line (EOL) marker. These character elements are actually very common as many protocols of the Internet Protocol (IP) Suite, such as HTTP, MIME, and NNTP, use them to discretely split the text into elements. As such, CRLF injection is when an attacker can inject a sequence of CRLF into one of these protocols or software applications; such as an HTTP stream. This is one of the attacks most common uses and as such, has the alternative names of HTTP Response Splitting and Neutralization of CRLF Sequences in HTTP Headers.

Firstly, we must define what a buffer is. A buffer is an allocated section of memory which can hold anything from a string of characters to an array of integers. That being the case, a buffer overflow (or overrun) is what happens a buffer with a fixed-length receives more data than what it can handle. In this case, the extra data has to be stored somewhere and spills over into an adjacent space in memory which can corrupt or overwrite the data stored there. These overflows usually result in a system crash; however, they also create opportunities for an attacker to run some malicious code or manipulate coding errors. The success of these attacks are very high as most programming languages, such as C, C++, and Fortran are vulnerable to these types of attacks.

It's now very easy doing online transactions on the go than ever before. Thanks to a mobility of devices and smartphones. However, if you are a person who likes connecting to free public Wi-Fi hotspots you need to be careful or avoid it altogether.

Cybersecurity deals with the protection of computer systems, networks, and data from cyber theft and damage to hardware, software and information. Cybersecurity is equally important for companies as well as individuals.

File sharing is something which is part of our daily activities. This is also commonly referred to as P2P or Peer-to-Peer sharing. This could be sharing files between two nodes in a network or between a client and a server or between two nodes not within the same network. Any multi-user environment will require a file sharing mechanism.

Since the WWW (World Wide Web) came into this world in 1990, fast growth is taking place in the professional, criminal and personal use of e-mails, the Internet, social networks, and computers. Those devices capture and create huge amounts of digital data which are stored in different places than most users realize. A user has less opportunity of terminating details-trails perfectly than of committing the great crime. Same as the fingerprint left on the chair adjustment of a vehicle used in the crime, a rough digital evidence (Fingerprint) always kept on speaking the truth.

InterPlanetary File System (IPFS) is a protocol which seeks to replace the Hypertext Transfer Protocol (HTTP) with the goal of having a truly decentralized Internet by changing how data is communicated across the World Wide Web (WWW). This is accomplished by a decentralized network where all devices on the network have hypermedia content stored and content-addressed for sharing. This process makes it similar to the World Wide Web (WWW), however, it is very different as it creates another network which works alongside a file system. The protocol was realized in 2014 by using the Bitcoin blockchain protocol and network as its framework which allowed it to store immutable data, handle duplicated files, and obtain addressing information across the network. This led to achieving faster speeds, more reliable performance, and better security than HTTP and HTTPS although it is not popular nor commonplace.

In the most rudimentary explanation, Single Sign-On authentication allows a single user to access multiple applications using the same credentials. Single Sign-On is also commonly referred to as "SSO". SSO is commonly used in enterprise-level systems that require access to multiple applications within the same Local Area Network, which is now expanded to include Wide Area Network.

Have you ever used a website that requires login information? Or been online shopping and realized that advertisements are suspiciously familiar with what you’ve been browsing at? Have you saved your financial information on your browser when making a purchase online? Online tracking allows you to save these details, enjoy (or despise) targeted advertising, and capture your login details on your favorite browser. While online tracking may provide some beneficial features, tracking can also introduce unprecedented security concerns you might not be aware of.

A blockchain is a decentralized digital ledger which is shared between every node on the network. For a device to become a node on a blockchain, a user must acquire that blockchain's token on the device so that it can be recognized as such and then be a part of the digital ledger. This ledger stores all of the data on each node across the system in such a way that it is all immutable; that is, it can never be modified or deleted. This process occurs simultaneously on all the machines on the network by having them solve a mathematical cryptographic puzzle which is heavy on the machine's computational power and can take a significant time to complete. This is the process which is called mining and a machine which is used for this is called a miner. Miners are typically in competition with each other to completely mine the transaction first as its only that miner who is rewarded with more tokens for completing the task. This is what has led to the cost of computer components costing so much as the demand for better hardware for miners has increased the price. One of the most popular of blockchains right now is the Bitcoin blockchain which functions as a cryptocurrency with a public digital ledger and was one of the very first to do this.
