RAM

RAS

random-access memory. Volatile memory that can be read and written by a microprocessor.

Registration, Admission, and Status Protocol. Protocol that is used between endpoints and the gatekeeper to perform management functions. RAS signalling function performs registration, admissions, bandwidth changes, status, and disengage procedures between the VoIP gateway and the gatekeeper.

RBCP	Router Blade Control Protocol. RBCP is based on SCP, but modified specifically for the router
	application. It is designed to run over Ethernet interfaces and uses 802.2 SNAP encapsulation for
	messages.

reassembly

recovery package

regex

regular expression

The putting back together of an IP datagram at the destination after it has been fragmented either at the source or at an intermediate node.

An IPS package file that includes the full application image and installer used for recovery on sensors.

See regular expression.

A mechanism by which you can define how to search for a specified sequence of characters in a data stream or file. Regular expressions are a powerful and flexible notation almost like a mini-programming language that allow you to describe text. In the context of pattern matching, regular expressions allow a succinct description of any arbitrary pattern.

Remote	See RADIUS.
Authentication Dial
In User Service
repackage release	A release that addresses defects in the packaging or the installer.
reputation	Similar to human social interaction, reputation is an opinion toward a device on the Internet. It enables
	the installed base of IPS sensors in the field to collaborate using the existing network infrastructure. A
	network device with reputation is most probably malicious or infected.
risk rating	RR. A risk rating is a value between 0 and 100 that represents a numerical quantification of the risk
	associated with a particular event on the network. The risk of the attack accounts for the severity,
	fidelity, relevance, and asset value of the attack, but not any response or mitigation actions. This risk is
	higher when more damage could be inflicted on your network.
RMA	Return Materials Authorization. The Cisco program for returning faulty hardware and obtaining a
	replacement.
ROMMON	Read-Only-Memory Monitor. ROMMON lets you TFTP system images onto the sensor for recovery
	purposes.
round-trip time	See RTT.
RPC	remote-procedure call. Technological foundation of client/server computing. RPCs are procedure calls
	that are built or specified by clients and are executed on servers, with the results returned over the
	network to the clients.
RSM	Router Switch Module. A router module that is installed in a Catalyst 5000 switch. It functions exactly
	like a standalone router.

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.
