Design patterns are proven solutions to recurring design problems in architecture as well as in software architecture and development. They thus represent a reusable template for problem solving that can be used in a specific context. In recent years, the design pattern approach has also attracted increasing interest in the field of human-computer interaction. Types of Design … [Read more...]

Arduino Light Sensor: Circuit and Code
A photoresistor, also known as a photoresistor or LDR, is a light-sensitive electrical resistor. The more light falls on the photoresistor, the smaller its resistance becomes. Compared to other light-sensitive electronic components such as photodiodes, photoresistors react very slowly. A thin layer of the photosensitive semiconductor material is applied to a ceramic substrate by sintering a … [Read more...]
Security Aspects of Mobile Banking
The term mobile banking refers to the processing of banking transactions that takes place with the help of mobile devices such as mobile phones or PDAs. It is possible to carry out mobile banking via special applications/widgets (small installed programs) or to access banking applications on the Internet directly via a mobile browser. Mobile banking differs from mobile payment, in which payment … [Read more...]

What is Whois Protocol
Whois is a protocol that can be used to query information about Internet domains and IP addresses and their owners ("registrants") from a distributed database system. Since its inception, Whois queries have been carried out primarily via the command line. Since corresponding client software was not available for all common operating systems, web-based frontends became established early on. Despite … [Read more...]
What is Pharming (Internet)?
Pharming is a scam method spread through the Internet. It is based on manipulating the DNS queries of web browsers (for example, through DNS spoofing) in order to redirect the user to fake websites. It is an evolution of classic phishing. Pharming has established itself as an umbrella term for various types of DNS attacks. One method to do this is to manipulate the host file locally. With the … [Read more...]
What is Information Security
Information security is a state of technical or non-technical systems for information processing, storage and storage, which is intended to ensure the protection goals of confidentiality, availability and integrity. Information security serves to protect against dangers or threats, to avoid economic damage and to minimize risks. In practice, information security in the context of IT security … [Read more...]
What is Vulnerability?
Vulnerable means flawed. Someone vulnerable to common cold has some flaw. In the field of information security, a security vulnerability or vulnerability is a flaw in software or hardware that allows a malicious program (exploit) or an attacker to penetrate a computer system. A vulnerability poses a threat to the security of a computer system. There is a risk that the vulnerability could be … [Read more...]
What is an Exploit (Software/IT)
In electronic data processing, an exploit is a systematic way to exploit vulnerabilities that have arisen during the development of a program. In this process, program codes are used to exploit security vulnerabilities and malfunctions of programs (or entire systems), usually to gain access to resources or to penetrate or interfere with computer systems. A zero-day exploit is the exploitation of a … [Read more...]
Who Are Crackers (computer security)
Crackers circumvent or break access barriers of computer systems and computer networks. This generally includes script kiddies and hackers who emphasize their activities on circumventing security mechanisms. In particular, the word encompasses programming experts who use cracking to undermine the protection mechanisms of software (from the unlawful manipulation of software, for example as part of … [Read more...]
