IT Security: Password guidelines and assistance
Passwords are a critical component of cybersecurity for any small business. Weak or easily guessed passwords can leave sensitive data and systems vulnerable to attack, while strong, complex passwords can help protect against unauthorized access. Here are some password guidelines that small businesses should follow:
Use strong, complex passwords: Passwords should be at least 8-12 characters long and include a combination of uppercase and lowercase letters, numbers, and symbols. Avoid using common words or phrases, as these can be easily guessed by attackers.
Don't reuse passwords: It's important to use a unique password for each account or system, as reusing passwords can make all accounts vulnerable if one is compromised.
Use a password manager: Password managers can help generate and store strong, unique passwords for each account, making it easier to keep track of multiple passwords without resorting to weak ones.
Implement two-factor authentication: Two-factor authentication adds an extra layer of security by requiring users to enter a code or use a security token in addition to a password. This can help prevent unauthorized access even if a password is compromised.
Enforce password expiration: Passwords should be changed regularly, typically every 90 days. This can help prevent attackers from using a compromised password to access systems or data over a long period of time.
Educate employees: It's important to educate employees on the importance of strong passwords and the risks of weak ones. This can include training on how to create strong passwords, how to recognize phishing attacks, and how to respond if a password is compromised.
Monitor password activity: Regular monitoring of password activity can help detect suspicious behaviour, such as multiple failed login attempts or unusual login locations.
Securely store passwords: Passwords should be stored in a secure location, such as a password manager or encrypted file. Avoid storing passwords in plain text or in easily accessible locations such as sticky notes.
Use unique usernames: Usernames should be unique and not easily guessable, as they can be used in combination with a password to gain access to an account.
Implement password policies: Small businesses should have a clear password policy in place that outlines the above guidelines and specifies consequences for non-compliance.
By following these guidelines, small businesses can improve their password security and reduce the risk of data breaches or other cybersecurity incidents. It's important to regularly review and update these guidelines as new threats emerge and best practices evolve.
