Do you really know who is accessing your most sensitive networked information assets? Unfortunately, security built on static, reusable passwords has proven easy for hackers to beat. With the advent of e-business, the need for rock-solid user authentication has never been more urgent. RSA SecurID two-factor authentication is based on something you know (a password or PIN), and something you have (an authenticator) - providing a much more reliable level of user authentication than reusable passwords.
