trusted certificate

trusted key

tune

Certificate upon which a certificate user relies as being valid without the need for validation testing; especially a public-key certificate that is used to provide the first public key in a certification path.

Public key upon which a user relies; especially a public key that can be used as the first public key in a certification path.

Adjusting signature parameters to modify an existing signature.

U

UDI

UDLD

Unique Device Identifier. Provides a unique identity for every Cisco product. The UDI is composed of the PID, VID, and SN. The UDI is stored in the Cisco IPS ID PROM.

UniDirectional Link Detection. Cisco proprietary protocol that allows devices connected through fiber-optic or copper Ethernet cables connected to LAN ports to monitor the physical configuration of the cables and detect when a unidirectional link exists. When a unidirectional link is detected, UDLD shuts down the affected LAN port and sends an alert, since unidirectional links can cause a variety of problems, such as, spanning tree topology loops.

UDP

User Datagram Protocol. Connectionless transport layer protocol in the TCP/IP protocol stack. UDP is

 

a simple protocol that exchanges datagrams without acknowledgments or guaranteed delivery,

 

requiring that error processing and retransmission be handled by other protocols. UDP is defined in

 

RFC 768.

unvirtualized sensing interface

UPS

UTF-8

To direct a router to remove a previously applied block.

See UDLD.

An unvirtualized sensing interface has not been divided into subinterfaces and the entire interfaces can be associated with at most one virtual sensor.

Uninterruptable Power Source.

Coordinated Universal Time. Time zone at zero degrees longitude. Formerly called Greenwich Mean Time (GMT) and Zulu time.

8-bit Unicode Transformation Format. A variable-length character encoding for Unicode. UTF-8 can represent every character in the Unicode character set and is backwards-compatible with ASCII.

V

VACL

VLAN ACL. An ACL that filters all packets (both within a VLAN and between VLANs) that pass

 

 

through a switch. Also known as security ACLs.

VID

Version identifier. Part of the UDI.

VIP

Versatile Interface Processor. Interface card used in Cisco 7000 and Cisco 7500 series routers. The VIP

 

 

provides multilayer switching and runs Cisco IOS. The most recent version of the VIP is VIP2.

IPS4510K9 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.
