{How do you manage your passwords for accessing Internet services, such as emails, Internet banking, online shopping, etc.? | |||
|type="()"} | |||
- I use the same password on multiple Internet services and never change it. | |||
||Having the same password on multiple Internet services means that a single compromised password will affect all of the services. You should set unique passwords on Internet services. | |||
- I follow a pattern (e.g. Tech0001, Tech0002, Tech0003) to create passwords and use them on multiple Internet services. | |||
||Using a pattern to create passwords is not a secure way as attackers can guess other passwords from a single compromised password. | |||
- I create unique passwords for accessing Internet services and record them in a text file, sticky notes, etc. | |||
||It’s generally not a good idea to record passwords in a text file or sticky notes as others may be able to read your passwords. If you really need to drop something down for memorizing your passwords, try writing password hints that only make sense to yourself. | |||
+ I create unique passphrases for accessing Internet services. | |||
||Good job! Passphrases have a good length and make it difficult to break. | |||
+ I use a reputable password manager to create, store and change my passwords regularly. | |||
||Well done! Password managers create random and complex passwords which are strong enough to withstand password breaking. | |||
{Is there any Antivirus software installed on your personal computer? | |||
|type="()"} | |||
- No, there is no Antivirus software installed on my personal computer | |||
||You should check the availability of Antivirus software for your operating system and consider installing one if it is available. The most popular operating system needs an Antivirus software to keep it safe from malware attacks. | |||
- Yes, an Antivirus software is installed on my personal computer but I am not sure whether it’s trustworthy. | |||
||Installing a questionable Antivirus software is as bad as no Antivirus installed. Some Antivirus are not effective in catching malwares, and some others are developed by hackers and act as a malware. You should uninstall the questionable Antivirus software and install a reputable one. | |||
- Yes, a reputable Antivirus software is installed on my personal computer. | |||
||It’s nice to have a reputable Antivirus software installed. The next step is to set it to update automatically. | |||
- Yes, a reputable Antivirus software is installed on my personal computer and it’s configured to update automatically. | |||
||Excellent! The Antivirus software will significantly reduce the risk of malware infection on your computer. | |||
