==Types of security appliances== * Active devices block unwanted traffic. Examples of such devices are firewalls, anti virus scanning devices, and content filtering devices. * Passive devices detect and report on unwanted traffic, such as intrusion detection appliances. * Preventative devices scan networks and identify potential security problems (such as penetration testing and vulnerability assessment appliances). * Unified Threat Management (UTM) appliances combine features together into one system, such as some firewalls, content filtering, web caching etc.
