Table B-25lists the parameters specific to the Service MSSQL engine.

Table B-25	Service MSSQL Engine Parameters

Parameter		Description	Value

password-present		Specifies whether or not a password was used in an MS SQL	true false
		login.

specify-sql-username		(Optional) Enables using an SQL username:	sa
		• sql-username—Specifies the username (exact match) of

For more information on the parameters common to all signature engines, see Master Engine, page B-4.

The Service NTP engine inspects NTP protocol. There is one NTP signature, the NTP readvar overflow signature, which fires an alert if a readvar command is seen with NTP data that is too large for the NTP service to capture. You can tune this signature and create custom signatures based on NTP protocol values, such as mode and size of control packets.

Table B-26lists the parameters specific to the Service NTP engine.

Table B-26	Service NTP Engine Parameters

Parameter		Description	Value

inspection-type		Specifies the type of inspection to perform.	inspect-ntp-packets
			is-invalid-data-packet
			is-non-ntp-traffic

inspect-ntp-packets		Enables inspection of NTP packets:	0 to 65535
		• control-opcode—Specifies the opcode
		number of an NTP control packet according
		to RFC1305, Appendix B.
		• max-control-data-size—Specifies the
		maximum allowed amount of data sent in a
		control packet.
		• mode—Specifies the mode of operation of
		the NTP packet per RFC 1305.

is-invalid-data-packet		Enables inspection of invalid NTP data packets	—
		and checks the structure of the NTP data packet
		to make sure it is the correct size.

is-non-ntp-traffic		Enables the inspection of nonNTP packets on an	—
		NTP port.

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.
