Fast Ethernet

Blocks traffic on the device after a hardware failure.

Lets traffic pass through the device after a hardware failure.

A signature is not fired when offending traffic is detected.

Normal traffic or a benign action causes a signature to fire.

Any of a number of 100-Mbps Ethernet specifications. Fast Ethernet offers a speed increase 10 times that of the 10BaseT Ethernet specification while preserving such qualities as frame format, MAC mechanisms, and MTU. Such similarities allow the use of existing 10BaseT applications and network management tools on Fast Ethernet networks. Based on an extension to the IEEE 802.3 specification.

Fast flux	Fast flux is a DNS technique used by Botnets to hide phishing and malware delivery sites behind an
	ever-changing network of compromised hosts acting as proxies. It can also refer to the combination of
	peer-to-peer networking, distributed command and control, web-based load balancing and proxy
	redirection used to make malware networks more resistant to discovery and counter-measures. The
	Storm Worm is one of the recent malware variants to make use of this technique.
firewall	Router or access server, or several routers or access servers, designated as a buffer between any
	connected public networks and a private network. A firewall router uses access lists and other methods
	to ensure the security of the private network.
Flood engine	Detects ICMP and UDP floods directed at hosts and networks.
flooding	Traffic passing technique used by switches and bridges in which traffic received on an interface is sent
	out all the interfaces of that device except the interface on which the information was received
	originally.
forwarding	Process of sending a frame toward its ultimate destination by way of an internetworking device.
fragment	Piece of a larger packet that has been broken down to smaller units.
fragmentation	Process of breaking a packet into smaller units when transmitting over a network medium that cannot
	support the original size of the packet.
Fragment	A processor in the IPS. Reassembles fragmented IP datagrams. It is also responsible for normalization
Reassembly	of IP fragments when the sensor is in inline mode.
Processor
FTP	File Transfer Protocol. Application protocol, part of the TCP/IP protocol stack, used for transferring
	files between network nodes. FTP is defined in RFC 959.
FTP server	File Transfer Protocol server. A server that uses the FTP protocol for transferring files between network
	nodes.
full duplex	Capability for simultaneous data transmission between a sending station and a receiving station.

IPS4520K9 specifications

Cisco Systems has long been a leading player in network security, and its IPS (Intrusion Prevention System) series is a testament to its commitment to safeguarding digital environments. Among its notable offerings are the IPS4510K9 and IPS4520K9 models, both designed to provide advanced threat protection for mid-sized to large enterprise networks.

The Cisco IPS4510K9 and IPS4520K9 are distinguished by their cutting-edge features that help organizations defend against a myriad of cyber threats. These systems utilize a multi-layered approach to security, integrating intrusion prevention, advanced malware protection, and comprehensive visibility across the network.

One of the primary characteristics of the IPS4510K9 is its high performance. It boasts a throughput of up to 1 Gbps, making it suitable for environments that demand rapid data processing and real-time responses to threats. The IPS4520K9, on the other hand, enhances that capability with improved throughput of up to 2 Gbps, accommodating larger enterprises with heavier network traffic. These models are equipped with powerful processors that support complex signature matching and can intelligently distinguish between legitimate traffic and potential threats.

In addition to performance, both models are designed with scalability in mind. They can be easily integrated into existing Cisco infrastructures. This facilitates a seamless enhancement of security without causing significant interruptions to ongoing operations. Moreover, they offer flexible deployment options, allowing organizations to operate them inline or out of band depending on their specific needs.

The Cisco IPS4510K9 and IPS4520K9 leverage advanced detection technologies, utilizing a variety of signature types and heuristic analysis to detect known and unknown threats effectively. They are equipped with real-time alerting and reporting capabilities, giving security teams immediate visibility into potential breaches and enabling them to respond swiftly.

Furthermore, both models support a range of management options through the Cisco Security Manager, allowing for centralized administration, streamlined policy management, and enhanced monitoring capabilities. Automated updates ensure the systems remain current with the latest threat intelligence, vital for staying ahead of evolving cyber threats.

In summary, the Cisco Systems IPS4510K9 and IPS4520K9 represent powerful solutions for organizations seeking robust intrusion prevention capabilities. With their high performance, scalability, and advanced detection technologies, these systems are essential tools in the ever-changing landscape of cybersecurity, providing enterprises with the peace of mind needed to operate securely in today's digital world.
