05 - Prevention of threats online

 1. The following list are methods that ….
Biometric Measures
Password Systems
CAPTCHA
Using email confirmations to confirm user identity
Automatic software updates

  would facilitate attacks and weaken a system or network

  would help prevent cyber security attacks if used correctly

  are developed by hackers to attack a system

  are developed by programmers to test a system

 2. Penetration testing can be carried out by people who simulate an attack on a system to expose …………..

  vulnerabilities

  redunduncies

  viruses

  variations

 3. A common form of biometric security scanning used in school canteens and mobile phones is:

  Automatic software updates

  telephone virus installations

  fingerprint scanners

  the use of CAPTCHAs

 4. One of the worst things you can do in terms of keeping passwords secure is to:
*What is known as a 'Hash' of the passwords is stored

  None of the above

  store encrypted passwords on a system

  store plain text passwords on a system

  store numerical passwords which are encrypted on a system

 5. A longer password is always better in terms of a hacker being able to brute force hack it.
a password that contains letters a - z and is 
seven characters long could take just 8 seconds to hack

On the other hand a password that contains letters a - z
and is fourteen characters long could take several million
hours to brute-force hack…

  TRUE

  FALSE

 6. Email confirmations are used to ensure that the person who has just signed up to a website is using a valid email address
A variation of this is the mobile phone code verification - this requires a person to have a mobile phone though!

  TRUE

  FALSE

 7. CAPTCHA stands for Completely Automated Public Turing Test to tell Computers and Humans apart

  TRUE

  FALSE

 8. CAPTCHAs exist to allow bots (automated non human robots) to automatically sign up to websites

  TRUE

  FALSE

 9. CAPTCHAs usually involve

  text that is large enough to be identified

  distorted text that only humans, but not computers can recognise

  typed text - usually in Arial font - so that it can be easily recognised

  text that is in another language (e.g. Arabic or Hebrew) that a comptuer cannot understand but a human may!

 10. Penetration testing can be very expensive but automated software updates ….

  can be turned on free and it usually fixes known vulnerabilities automatically

  can only be carried out by the government

  are also expensive and usually do not fix any vulnerabilities

  None of the above

 11. With emails it is a good idea to get a suitable spam filter but it is not necessary to check attachments and their source before downloading

  FALSE

  TRUE

 12. _______measures can be used to lock down a device to a certain or specific person using _________ info specific to them

  malware

  biometric

  computer

  validation

 13. In modern society it is perfectly fine and completely safe to just use passwords as a security measure.

  TRUE

  FALSE

 14. This is a type of attack where a small piece of code attacks a system and then demands payment( cryptocurrency, or digital money) for the release of the network.

  measureware

  ransomware

  bitcriminalware

  cryptoware

 15. If all else fails, one important thing to remember to do in case your system/website is targeted and destroyed by hackers is to:

  always email yourself a copy of your password

  always make a backup

  always use a dry wipe for the screen monitor

  always tell at least five other close friends your password and login details
