Logins to sensitive systems using standard UserID and Password is just not secure enough. Simple network sniffing utilities such as tcpdump or freely-available hacking / phishing tools from the Internet will easily enable a malicious user to get hold of the login credentials of an inattentive or overworked system administrator. This is where 2-factor authentication becomes important. By using the DS3 2FA PAM plugin, the root or any other critical account can be configured to require both the password, as well as the OTP (One-time Password) in order to authenticate the administrator. To obtain the OTP, the administrator can have a choice of either a physical hardware OTP token, a software OTP token running in Windows or even a software J2ME token running in the mobile phone. |
