A good password is an essential element of online security. It is the first line of defense against cyberattacks and the first point of entry into any website or application. Therefore, it is crucial to choose a strong and effective password that is difficult for hackers to guess or crack. Here are four things that make a good password:
1. Complexity: A good password should be complex and difficult to guess. It should include a combination of upper-case and lower-case letters, numbers, and symbols. A long password with a mix of characters makes it challenging for cyber attackers to crack it.
2. Unpredictability: A good password should not be something that can be easily guessed by others. For example, an easily guessable password might be the name of a pet or a birth date. Instead, it should be completely random and not connected to any personal information.
3. Unique: A good password should be unique to each application or website. Often, hackers use automated bots to try out the same password on multiple sites. If you have the same password across multiple sites, it is easier for them to gain access.
4. Frequently changed: A good password should be changed regularly. It can be difficult to remember multiple complex passwords, but it is important to update passwords, especially for frequently-used sites such as banking or email. Updating passwords regularly means that if a password is compromised, the hacker will not be able to use it for long.
A good password ensures the safety and security of our online activities. By following the above guidelines, we can help protect our sensitive data from falling into the wrong hands.

What are 4 uses of password?
A password is a secret word or set of characters that grants access to a device, application or account. It is an essential aspect of modern technology that enables users to keep their personal and sensitive information secure. Here are four main uses of passwords:
1. Access Control- Passwords are primarily used for access control purposes. They allow users to restrict access to their devices, applications or accounts to authorized persons only. Passwords are commonly used to secure accounts on social media platforms, email accounts, online banking portals, and other platforms that require authentication.
2. Verification- Passwords serve as a means of verification. In certain situations where security is mandatory, passwords help in verifying the identity of the users. The user has to enter the right password to prove their identity, and this aids in preventing unwanted access and misuse of the system.
3. Encryption- Passwords are used to encrypt data and information. Passwords protect confidential data such as medical records, banking transactions, or business information from unauthorized access. Passwords make it difficult for intruders to obtain access to sensitive data and ensure its security during transmission over the internet.
4. Personalization- Passwords can also be used for personalization. Passwords allow users to customize their devices, applications or accounts to reflect their preferences and interests. For instance, they could change the wallpaper or add a distinctive background to the login screen to provide a unique and personalized user experience.
Passwords serve several purposes in the digital world, including control access to devices and applications, provide personalization, perform verification, and offer encryption. It is important for users to create strong and unique passwords and keep them secure to ensure the maximum level of security and protection.
What is 4 distinct characters?
4 distinct characters refer to four unique and individual symbols, letters, or numerical digits that are different from one another and do not repeat. For example, “abcd” or “@#34” can be considered as 4 distinct characters. These characters are essential in various fields like computer programming, cryptography, and data entry, where unique identification or differentiation of elements is necessary. In computer programming, 4 distinct characters are commonly used for naming variables or functions to make them easily identifiable and to avoid confusion with other elements. Similarly, in cryptography, 4 distinct characters are used as keys to encrypt or decrypt data and to ensure the security and confidentiality of information. 4 distinct characters play a critical role in many applications, and their proper identification and utilization are vital for efficient and effective functioning of the systems.
What is Cisco Type 4 password?
Cisco Type 4 password, also known as SHA-256-based password encryption, is a method used by Cisco routers and switches to protect login credentials and access to network devices against unauthorized access.
This method is an upgrade from the previous Type 5 password hashing technique, which used the weaker MD5 algorithm for encryption. The SHA-256 algorithm used in Type 4 encryption is more secure and less susceptible to password cracking attempts.
The Cisco Type 4 password uses a salted hash format to encrypt passwords. The password is first salted using a unique salt value before being hashed using the SHA-256 algorithm. The salt value is a randomly generated string of characters that is unique to each password hash, and it is added to the password before hashing to ensure that each password hash is unique and not easily susceptible to dictionary attacks.
The Type 4 password encryption is commonly used in network environments that require high levels of security, such as financial institutions, government agencies and large corporations. It allows network administrators to secure access to routers and switches while ensuring the confidentiality and integrity of login credentials.
To configure Cisco Type 4 password encryption, network administrators can use the command-line interface (CLI) of their Cisco devices, or use network management tools such as Cisco Prime Infrastructure or Cisco DNA Center.
Cisco Type 4 password encryption is a secure and robust method of protecting login credentials and network devices against unauthorized access. It is a significant upgrade from the previous Type 5 encryption, and its use is highly recommended in environments where security is a top priority.
What are four 4 suitable criteria to be inserted in password policy?
A strong password policy is essential for the security and protection of any organization’s sensitive and confidential data. Building an effective password policy requires careful consideration of criteria that will strengthen the password strength of users that interact with the system. Four suitable criteria for a password policy are:
1. Password Complexity: The complexity of a password is an essential criterion for the password policy. A strong password should have a combination of uppercase and lowercase letters, numbers, and symbols. It should be at least eight characters long and should not include any predictable patterns or dictionary words. This helps to ensure that passwords are hard to guess and can prevent brute force attacks which are hackers trying every possible combination of characters to guess a password.
2. Password Expiration: Another important criterion for password policies is determining the frequency at which users should change their passwords. It is recommended that passwords should be changed every 60-90 days to reduce the risks of unauthorized access. Passwords should not be stored on paper or be shared with others.
3. Two-factor Authentication: Two-factor authentication is another critical criterion for password policies. It involves using an additional security measure to authenticate users, such as a one-time password sent to a user’s mobile device. This strengthens the password by requiring both something the user knows (a password, PIN), and something the user has (a token, security key, mobile device). This dual authentication has become widely used in a number of applications recently as it provides an additional layer of security without creating too much of an operational interruption.
4. Account Lockout: A password policy should also have provisions for account lockout or temporary account suspension. This will automatically lock or suspend user accounts after several unsuccessful login attempts. This precautionary measure stops hackers who try to guess passwords through ‘Brute force’ attack methods. Locking accounts creates time delays hence frustrating their efforts and making it less likely that any attacker will be able to manage to guess the password within the set time limit.
These four criteria are essential in developing a password policy that will ensure the security of user accounts and prevent unauthorized access to sensitive data. By making a password complex, requiring regular changes, providing dual-factor authentication, and setting account lockout parameters, organizations can prevent many common types of attacks and threats to their critical data.
What makes a password strong instead of weak?
A strong password is one that is difficult to guess or hack. There are several factors that make a password strong. Firstly, a strong password should be long. Passwords that are short are easier to guess because they have fewer possible combinations. Generally, a password should be at least 8 characters long, with many experts recommending a minimum of 12 characters.
Secondly, a strong password should contain a mix of letters (both upper and lower case), numbers, and symbols. This makes it more difficult for anyone to guess or crack the password. Using familiar or common words in a password makes it weak because they can be easily guessed.
Thirdly, a strong password should not contain any personal information that can be easily guessed by anyone. Passwords should not contain common words or patterns that can be easily guessed or figured out like birthdates, names, phone numbers or other identifying information.
Another important factor in creating a strong password is using a unique password for each online account. Reusing the same password for different accounts is dangerous because if one account is compromised, hackers can use that password to gain access to several other accounts as well.
Lastly, a strong password should be changed regularly. Changing passwords at regular intervals limits the amount of time a hacker can have access to an account. It also minimizes the data that could be breached if one’s password is compromised.
Using a combination of length, complexity, uniqueness, and regular change is what makes a password strong. With these practices in mind, one can create strong passwords that are difficult for hackers to guess or compromise.
What are 3 characteristics of a weak password?
Three characteristics of a weak password can include its length, complexity, and predictability. A weak password typically has a relatively short length, often consisting of only a few characters, making it relatively easy for a hacker or cybercriminal to guess or decipher. Additionally, a weak password may lack complexity, such as having a simple combination of letters, numbers, or symbols, rather than a more complex mix of these elements. Predictability is another characteristic of a weak password, which means that it may be based on easily guessed personal information, such as a person’s name, birthdate, or other identifying data. A weak password makes it easy for cybercriminals to break into online accounts and gain unauthorized access, making it a major security risk. Therefore, it is important for individuals and organizations to create strong passwords that have a significant length, complexity, and are not predictable. A strong password is one that is considerably harder to guess or break, helping to keep sensitive information and data safe from potential cyberattacks.
