Unit 4: Question 2
Create or find a classroom resource that teaches students about creating strong passwords, passcodes or passphrases.
For personal accounts such as Gmail, Facebook, Instagram accounts, etc., the best advice for you is to use strong passwords to protect your account from being logged in and illegally used by others. permission.
Choosing a password for personal accounts such as Email, bank accounts, social networks … is similar to choosing a lock to store your treasure. If the lock is outdated or too simple, you can lose your property to hackers.
What is a strong password?
A strong password is one that you cannot guess or crack using a Brute Force attack. Hackers use computers to try different combinations of letters, numbers, and symbols to find the right password. Modern computers can crack short passwords consisting of only letters and numbers in seconds.
As such, a strong password consists of a combination of upper and lower case letters, numbers, and special symbols, such as punctuation marks. They should be at least 12 characters long, even longer the better.
Overall, here are the key characteristics of a good, secure password:
• Be at least 12 characters long. The longer the password – the better.
• Use upper and lower case letters, numbers and special symbols. Passwords that include mixed characters are harder to crack.
• Does not contain easy-to-remember keyboard sequences.
• Not based on your personal information.
• Passwords are unique for each account you have.
When you set up your account online, there will often be a prompt prompting you to include numbers or certain characters. Some may even prevent you from setting a “weak password,” which is usually an easy-to-guess combination of words or numbers.
But even if you’re not prompted to set a strong password, it’s really important to do so, whenever you’re setting up a new online account or changing the password for any existing account.
So how to choose a password?
Today’s experts advise us: “Choose a sentence of your own and its meaning must be personal”. This makes your password unique but easy for you to remember.
1. Effective password generation and management program
With each website that requires creating an account to be used like Facebook, Instagram, etc., it is extremely difficult to “remember” login passwords because each account will have its own password. .
Therefore, using a password management program is the solution to help you manage the most effective “password chain”. Just create a password that is strong enough and easy to remember.
If you use a password manager, there’s only one thing you need to remember, and that’s your master password. Think of your password manager as a digital vault that keeps all your logins secure. You just need to enter the correct code to access that store of information.
So, try one of the methods in the following section of the article to create a master password, then use that to store the rest of the passwords. This also means that you can come up with really special codes that no one else would think of – because you don’t even have to remember them.
It’s important not to use the same password for multiple accounts, and password managers simplify that.
Some good password managers also generate your passwords for you, so you won’t even have to create your own!
2. Tips for creating strong passwords
2.1. Create a password with at least 12 characters
Choose a password of sufficient length, between 12 and 14 characters is reasonable. Multi-character passwords are always more secure than passwords with fewer characters.
2.2. Combination of alphanumeric characters, symbols, uppercase letters, lowercase letters
Using a password consisting of different characters increases the security and safety of your account. When using these types of passwords, it is difficult for hackers to “hack” your account password.
2.3. Create a rhyming password – Nursery Rhymes
The method that many people like to use, and is also able to ensure good security policies on the Internet, even those that require passwords up to 15 characters long, is the rhyming password method.
For example: “It is very sunny today. Kittens go to school with nothing.”
Is a verse familiar to you. So the password you can generate is:
“6hntnccMcdhcmtg!”
It’s a strong password, 16 characters long including numbers, uppercase, lowercase letters and at least one special character.
2.4. A sentence from a song or the name of your favorite movie
A similar method is applied to a password taken from a verse in a song or movie title you like. Using a movie you like, but few people know will make the password even more secure. You can also replace it with the names or famous sayings of the characters, combined with the numbers specified for the first letter of a syllable to make the password more difficult to guess.
Example with a sentence of the character Al Pacino in the famous movie Scent of a Woman:
“If I were the same man that I was thirty years ago I’d take a flamethrower to this place!”
Replace the “t” with the number 3. This quote then becomes the password:
“IIw36m3Iw3yaI3af33p!”
2.5. Use Technical Terminology
Another interesting method is to use technical terms in different professions. Each is an expert in his or her own career field. Based on that, you can choose a technical term that you are familiar with to create a strong password.
For example, if you are a nurse or doctor the phrase you may have to memorize for sure to work is:
“ARDS: Acute respiratory distress syndrome: acute respiratory distress syndrome”
You can replace the character “a” with a zero to create your own password like this:
“A0rdshcspct#”
This is just a 12-character password, but it’s hard to guess.
2.6. Your special day
Another method for creating strong and easy to remember passwords is mainly numbers. Of course, random numbers will make you forget. You should choose numbers based on dates that are particularly important to you.
This method makes many people immediately think of using birthdays. However, this is especially flawed because those are numbers that others can know very easily, especially hackers. Therefore, you should choose a date to record an event that is special to you but no one knows but you.
For example, it was the day that you first got a bicycle. The day you kissed for the first time. The day you travel abroad…
So you have 3 important dates. You put those numbers on the same password and separate it with dashes, ending with a special character like a pound sign.
Eg: “10l08l86_03l14l94_09l06l98#”
This password is up to 20+ characters, so it can only be used in systems that can handle very long passwords. However, it will give you one of the most secure passwords. You can take a day off to reduce the number of characters to match the password requirements in your account.
2.7. Use keymap
Like the password method in smartphone models. You rely on the keyboard pattern to generate your own passwords.
With this method, you can draw recognizable images or letters on the keyboard. In the above case, the generated password is:
“3waxcvgy7890-=”
Using this method, you can change to lengthen the password. A hacker could potentially run an algorithm to figure out your password, so it’s a good idea to invent more complex patterns such as one-key travel, diagonal travel to keep your password secure. friend.
2.8. Make a rough password and divide it into parts
This method makes the password secure, but it is crude and easy to implement.
You create passwords and print them out into 2 different cards. Each separate card will be part of the password that you need to remember.
For example, your password might be “2BeOrNot2BeThatIsThe?”
So you will have the tag “ThatIsThe?” to remind of “2BeOrNot2Be” and can be stored in 2 different places.
The value here is that even if someone finds your password part, they still won’t have the other half only you remember.
3. Tips for creating strong passwords that are still easy to remember
(illustration)
With some of the tips above, you can easily create a strong password for your account.
For example, you can create a 16-character password like 3o(t&gSp&3hZ4#t9, which combines quite a few different character formats and randomly arranged characters. This way, hackers will not be able to “hack” and gain unauthorized access to your account.
However, the problem that the Network Administrator wants to emphasize here is how to remember this password?
Assuming you don’t have a camera to capture and save this password, you have to spend a long time “stuffing” these characters into your brain.
Generated passwords consist of different character formats arranged in a random order, which is difficult to remember, so the best way to manage passwords is to use password management programs. .
However, if you do not want to use password management programs, you can also be flexible, applying some tips to “remember” such passwords.
For example, you can easily remember this string of passwords by remembering the saying: the first house I lived in was at 224/2B Ha Hoang Ho Street, My Xuyen Ward, Long Xuyen City, An Giang Province.
If set as password for this sentence will be “ThfIeliw613FS.Rw$4pm”. This password is quite strong, consists of 21 characters with all uppercase letters, lowercase letters, symbols and numbers interspersed with each other. You just need to remember the above 2 sentences to be able to remember the password easily.
In general, the way to set a strong and easy to remember password according to the above methods is not necessarily “safe”. For example, if you use the same password for many accounts, if the password is leaked on any account, other accounts will easily be “intruded” illegally.
Ideally, for each account you use a different unique password, avoid phishing sites and keep your computer free of malware.
In a nutshell, the best password is one that has your unique personal touches. You can use the methods above or combine them to suit you best. The above are suggestions to help you create a strong and virtually unbreakable password that is easy for you to remember.
