Potential Threats
Cards in this deck (11)
- 1VirusesA computer virus is a software program that is designed to copy itself over and over again and to attach itself to files and programs. Just as bacteria and micro-organisms can infect humans.
- 2TrojanA trojan program can appears to be just a harmless application but will run in the background performing something malicious.
- 3WormA computer worm behaves in a similar way to a virus, but it does not necessarily harm files. Instead, it tries to copy itself so many times that the whole system runs out of resources and crashes.
- 4Malware (Malicious Hardware)This can range from forcing your browser to display unwanted pop-up advertisements, spy on your computer, looking for personal information, passwords and so on., and even cause a pop-up to appear on your screen which will say something like 'Your computer has a virus. To clear the problem please purchase this software', and a link is provided in the pop-up.
- 5RootkitsRootkits give other people permissions and access to your computer, allowing them to take it over remotely and do whatever they like.
- 6PhishingPhishing is the fraudulent attempt to obtain sensitive information such as usernames, passwords and credit card details by disguising as a trustworthy entity in an electronic communication. E.G. emails, text messages.
- 7Social engineeringSocial engineering is the psychological manipulation of people into performing actions or divulging confidential information.
- 8Poor network policyWhere a network does not have security rules in place for users to follow. People. Where users do not adhere to network policy.
- 9Brute force attacksA brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly.
- 10DDoS (Distributed Denial-of-Service)A denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet.
- 11SQL Injection (Structured Query Language)SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution.
