Types of Malware

 Types of Malware - Test Yourself 

 

Adware 

Adware is advertising-supported software. This is any software package which automatically shows adverts, such as pop-ups. It may be used in the user interface of a software package or on an installation screen. Adware is mostly harmless, whereas in some circumstances, some adware may include spyware such as key-loggers.  

 

Key-Logger 

Key loggers can be installed in two different forms. They can be legitimately installed to monitor users or can be installed maliciously. Key-loggers collect information and send it back to a third party. Some key-loggers only collect keyboard strokes into one website or application. Others record every keyboard stroke including any information/data that is cut and pasted.  

 

(RAT0 Remote access Trojan/Trojan  

RAT’s access and infect digital systems. RAT’s are typically installed without user consent and remain hidden to avoid detection. This allows a hacker to control your device remotely. RAT’s are typically downloaded on a what seems to be like legitimate program, like a game. As a trojan is any malware that misleads users of it’s true intent by disguising it’s self as a standard program, the Greek story of a wooden horse being snuck into the town of troy unnoticed.  

 

Ransomware 

Ransomware is a virus that holds a digital system captive and demands a ransom, usually money, to release it. Ransomware can restrict user access to a computer system by either encrypting files or locking down the computer system. A message is usually displayed to force the user to pay the ransom. It is spread like a worm and can be started by downloading an infected file or vulnerability on the computer system. 

 

Spyware 

Spyware can collect data from an infected digital system, including personal information like websites visited, user logins and financial information. Spyware is usually hidden from a user and is harder to detect. It is usually secretly installed on a user's computer without their knowledge. Some examples of spyware include; Key-loggers, info stealers and rootkits.  

 

Virus  

A virus attempts to make a digital system vulnerable. Viruses’ work by having a computer program that replicates itself and spreads from computer to computer. Viruses increase their chances of spreading to other computers by infecting files on a network file system or a file system accessed by other computers. Examples of viruses include: Trojan horses and a browser hijacker.

Topologies

 Topologies What is a network topology? A network topology is the arrangement of the elements, such as links and nodes, of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks and computer networks.  Network topology examples Point to point topology -      This is arguably the most basic topology as it only consists of 2 nodes and a connection between them. So for example, if you were to configure a router in London, to connect and use resources on a network in Manchester, you would want to make sure that you had a link between them that supports your needs.  Star topology - A star topology is a centralised topology consisting of multiple nodes and a central hub/switch. It is also a design where all devices are connected to a central hub or switch, and messages are passed to the central core that, in turn, passes the

Emerging technologies allowing adaptability and future proofing

  Emerging technologies allowing adaptability and future proofing Machine Learning Machine Learning is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalise to unseen data, and thus perform tasks without explicit instructions. Advances in the field of deep learning have allowed neural networks to surpass many previous approaches in performance.   Artificial Intelligence (AI) Artificial Intelligence is a set of technologies that enable computers to perform a variety of advanced functions, including the ability to see, understand and translate spoken and written language, analyse data, make recommendations and more.   Internet of things (IoT) The internet of things refers to a network of physical devices, appliances and other physical objects that are embedded with sensors, software and netw...
