Securing Windows Server 2008: Prevent Attacks from Outside and Inside Your Organization
To change a password on the Ubuntu server, you can follow these steps:
- Log in to your Ubuntu server as an administrator or with sudo privileges.
- Open a terminal or SSH into the server.
- Use the passwd command, followed by the username whose password you want to change. For example, to change the password for a user named "ubuntuuser," type: passwd ubuntuuser
- You will be prompted to enter the new password twice. Type the new password and press Enter. Note that while typing the password, no characters will be displayed on the screen for security reasons.
- If the password change is successful, a message confirming the password update will be displayed.
After following these steps, the password for the specified user on the Ubuntu server should be changed to the new one you entered.
Is there a requirement to change the password periodically?
The requirement to change passwords periodically varies depending on the policies implemented by the organization or the individual's preference for their personal accounts. In the past, it was a common practice to enforce regular password changes to enhance security. However, current guidelines from many cybersecurity experts suggest that regularly changing passwords may not necessarily improve security and can even lead to weaker passwords being used. Instead, it is generally recommended to use strong, unique passwords and enable multi-factor authentication to enhance account security.
Are there any specific password requirements?
Many platforms and websites do have general password requirements to enhance security. These requirements often include a minimum length, a mix of uppercase and lowercase letters, numbers, and special characters. It is important to use a unique and strong password for each online account you create to protect your personal information. For specific password requirements, it's best to consult the platform or website's documentation or guidelines.
