3DES

G L O S S A R Y

Revised: July 16, 2012

Triple Data Encryption Standard. A stronger version of DES, which is the default encryption method for SSH version 1.5. Used when establishing an SSH session with the sensor. It can be used when the sensor is managing a device.

802.xA set of IEEE standards for the definition of LAN protocols.

A

AAA

authentication, authorization, and accounting. Pronounced “triple a.” The primary and recommended

 

method for access control in Cisco devices.

ACE

Access Control Entry. An entry in the ACL that describes what action should be taken for a specified

 

address or protocol. The sensor adds/removes ACE to block hosts.

ACK

acknowledgement. Notification sent from one network device to another to acknowledge that some

 

event occurred (for example, the receipt of a message).

ACL

Access Control List. A list of ACEs that control the flow of data through a router. There are two ACLs

 

per router interface for inbound data and outbound data. Only one ACL per direction can be active at a

 

time. ACLs are identified by number or by name. ACLs can be standard, enhanced, or extended. You

 

can configure the sensor to manage ACLs.

ACS server

Cisco Access Control Server. A RADIUS security server that is the centralized control point for

 

managing network users, network administrators, and network infrastructure resources.

action

The response of the sensor to an event. An action only happens if the event is not filtered. Examples

 

include TCP reset, block host, block connection, IP logging, and capturing the alert trigger packet.

active ACL

The ACL created and maintained by ARC and applied to the router block interfaces.

adaptive security

ASA. Combines firewall, VPN concentrator, and intrusion prevention software functionality into one

appliance

software image. You can configure the adaptive security appliance in single mode or multi-mode.

AIC engine

Application Inspection and Control engine. Provides deep analysis of web traffic. It provides granular

 

control over HTTP sessions to prevent abuse of the HTTP protocol. It allows administrative control

 

over applications that try to tunnel over specified ports, such as instant messaging, and tunneling

 

applications, such as gotomypc. It can also inspect FTP traffic and control the commands being issued.

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.
