A O Whitelisting depends on government-certified lists of trusted software providers, whereas blacklisting needs to recognize patterns of malicious code behavior, or malware signatures, to block the malware from being installed and executed. B O C O D With blacklisting only, new malware may not be recognized as such before it installs, executes, and begins to harm your systems and information. Administering a whitelisting system can require a lot of effort, but when an unknown program is trying to execute (or be installed), you know it is not yet trusted and can prevent harm. O For most organizations, the list of applications they have chosen to trust is far smaller and easier to administer than huge lists of malware signatures and behavioral models.
