Chapter 3 Setting Up the Sensor

Configuring Authentication and User Parameters

Step 7 Set the number of old passwords to remember for each account. A new password cannot match any of the old passwords of an account.

sensor(config-aut-pas)# number-old-passwords 3

Step 8 Check your new setting.

sensor(config-aut-pas)# show settings password-strength

-----------------------------------------------

size: 8-64 <defaulted>

digits-min: 6 default: 0

uppercase-min: 3 default: 0

lowercase-min: 3 default: 0

other-min: 3 default: 0

number-old-passwords: 3 default: 0

-----------------------------------------------

sensor(config-aut-pas)#

For the procedures for recovering sensor passwords, see Recovering the Password, page 17-2.

Locking User Accounts

Use the attemptLimit number command in authentication submode to lock accounts so that users cannot keep trying to log in after a certain number of failed attempts. The default is 0, which indicates unlimited authentication attempts. For security purposes, you should change this number.

To configure account locking, follow these steps:

Step 1 Log in to the sensor using an account with administrator privileges.

Step 2 Enter service authentication submode.

sensor# configure terminal

sensor(config)# service authentication

Step 3 Set the number of attempts users will have to log in to accounts.

sensor(config-aut)# attemptLimit 3

Step 4 Check your new setting.

sensor(config-aut)# show settings attemptLimit: 3 defaulted: 0

sensor(config-aut)#

Step 5 Set the value back to the system default setting.

sensor(config-aut)# default attemptLimit

Step 6 Check that the setting has returned to the default.

sensor(config-aut)# show settings attemptLimit: 0 <defaulted>

sensor(config-aut)#

Step 7 Check to see if any users have locked accounts. The account of the user jsmith is locked as indicated by the parentheses.

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.
