IDSs and IPSs also can be classified as knowledge-based (or signature-based) or behavior-based (or statistical anomaly-based) systems:
* A knowledge-based system uses a database of known vulnerabilities and attack profiles to identify intrusion attempts. These types of systems have lower false-alarm rates than behavior-based systems but must be continually updated with new attack signatures to be effective.
* A behavior-based system uses a baseline of normal network activity to identify unusual patterns or levels of network activity that may be indicative of an intrusion attempt.
These types of systems are more adaptive than knowledge-based systems and therefore may be more effective in detecting previously unknown vulnerabilities and attacks, but they have a much higher false-positive rate than knowledge-based systems

Explanation

Short-range wireless:
Adaptive Network Technology+ (ANT+): ANT+ is a proprietary multicast wireless sensor network technology primarily used in personal wearables, such as sports and fitness sensors.
Bluetooth/Bluetooth Low-Energy (BLE): Bluetooth is a low-power, short-range communications technology primarily designed for point-to-point communications between wireless devices in a hub-and-spoke topology. BLE (also known as Bluetooth Smart or Bluetooth 4.0+) devices consume significantly less power than Bluetooth devices and can access the internet directly through 6LoWPAN connectivity.
Internet Protocol version 6 (IPv6) over Low-Power Wireless Personal Area Networks (6LoWPAN): 6LoWPAN allows IPv6 traffic to be carried over low-power wireless mesh networks. 6LoWPAN is designed for nodes and applications that require wireless internet connectivity at relatively low data rates in small form factors, such as smart light bulbs and smart meters.
Wi-Fi/802.11: The Institute of Electrical and Electronics Engineers (IEEE) defines the 802 LAN protocol standards. 802.11 is the set of standards used for Wi-Fi networks typically operating in the 2.4GHz and 5GHz frequency bands. The most common implementations today include:
802.11n (labeled Wi-Fi 4 by the Wi-Fi Alliance), which operates on both 2.4GHz and 5GHz bands at ranges from 54Mbps to 600Mbps
802.11ac (Wi-Fi 5), which operates on the 5GHz band at ranges from 433Mbps to 3.46 Gbps
802.11ax (Wi-Fi 6), which operates on the 2.4GHz and 5GHz bands (and all bands between 1 and 6GHz, when they become available for 802.11 use) at ranges up to 11Gbps Z-Wave: Z-Wave is a low-energy wireless mesh network protocol primarily used for home automation applications such as smart appliances, lighting control, security systems, smart thermostats, windows and locks, and garage doors.
Zigbee/802.14: Zigbee is a low-cost, low-power wireless mesh network protocol based on the IEEE 802.15.4 standard. Zigbee is the dominant protocol in the low-power networking market, with a large installed base in industrial environments and smart home products.

SaaS – User responsible for only the data, vendor responsible for rest

New software vulnerabilities and exploits are discovered all the time and thus diligent software patch management is required by system and security administrators in every organization.

Cloud computing is not a location but rather a pool of resources that can be rapidly provisioned in an automated, on-demand manner.

Explanation
Multiple policies, no policy reconciliation tools: Sequential traffic analysis (stateful inspection, application control, intrusion prevention system (IPS), anti-malware, etc.) in traditional data center security solutions requires a corresponding security policy or profile, often using multiple management tools. The result is that your security policies become convoluted as you build and manage a firewall policy with source, destination, user, port, and action; an application control policy with similar rules; and any other threat prevention rules required. Multiple security policies that mix positive (firewall) and negative (application control, IPS, and anti-malware) control models can cause security holes by missing traffic and/or not identifying

Explanation
App-ID™ technology leverages the power of the broad global community to provide continuous identification, categorization, and granular risk-based control of known and previously unknown SaaS applications, ensuring new applications are discovered automatically as they become popular.
