Chapter 5 Configuring the Adaptive Security Appliance

Before Launching the Startup Wizard

In addition to its complete configuration and management capability, ASDM features intelligent wizards to simplify and accelerate the deployment of the adaptive security appliance.

To use ASDM, you must have a DES license or a 3DES-AES license. In addition, Java and JavaScript must be enabled in your web browser.

In addition to the ASDM web configuration tool, you can configure the adaptive security appliance by using the command-line interface. For more information, see the Cisco Security Appliance Command Line Configuration Guide and the Cisco Security Appliance Command Reference.

Before Launching the Startup Wizard

Before you launch the Startup Wizard, perform the following steps:

Step 1 Obtain a DES license or a 3DES-AES license.

To run ASDM, you must have a DES license or a 3DES-AES license. If you did not purchase one of these licenses with the adaptive security appliance, see Appendix A, “Obtaining a DES License or a 3DES-AES License” for information about how to obtain and activate one.

Step 2 Enable Java and Javascript in your Web browser.

Step 3 Gather the following information:

A unique hostname to identify the adaptive security appliance on your network.

The IP addresses of your outside interface, inside interface, and any other interfaces.

The IP addresses to use for NAT or PAT configuration.

The IP address range for the DHCP server.

ASA 5500 specifications

Cisco Systems ASA 5500 is a robust security appliance designed to provide advanced network security and protection against both internal and external threats. Ideal for organizations of various sizes, the ASA 5500 series offers a wide range of features that combine firewall capabilities with intrusion prevention, VPN support, and application control, among others.

One of the key features of the ASA 5500 is its stateful firewall technology. This allows the device to monitor active connections and enforce security policies based on the state of the traffic. By maintaining the context of network sessions, the firewall can make informed decisions on whether to allow or deny traffic based on established rules.

In addition to traditional firewall functionalities, the ASA 5500 series integrates advanced intrusion prevention capabilities. By analyzing traffic patterns and identifying known threats, the IPS functionality helps organizations defend against a variety of malicious activities, such as DDoS attacks, malware, and unauthorized access attempts. The ASA 5500 continuously updates its threat intelligence through Cisco's global threat database, enhancing its ability to detect emerging threats in real-time.

Virtual Private Network (VPN) support is another significant aspect of the ASA 5500 series. The device offers secure, encrypted connections for remote users and branch offices, ensuring safe access to corporate resources over the Internet. It supports both IPsec and SSL VPN protocols, allowing organizations to choose the best option for their specific needs. This capability is crucial for businesses that require a secure environment for remote work.

The ASA 5500 series also features extensive application control and visibility tools. These tools enable organizations to manage and control the applications running on their network, ensuring that only authorized applications can communicate through the firewall. This level of control helps to mitigate risks associated with unauthorized applications, which can lead to data breaches or reduced productivity.

Moreover, the ASA 5500 is designed with high availability and scalability in mind. Its clustering support ensures that multiple units can work together to provide redundancy and load balancing, enhancing both performance and reliability. This characteristic is especially important for organizations looking to maintain continuous operation during traffic spikes or hardware failures.

In summary, Cisco Systems ASA 5500 is an all-in-one security solution that combines stateful firewall protection, intrusion prevention, VPN capabilities, and application control. With its robust feature set and focus on security, it is well-suited for organizations seeking to protect their networks from an ever-evolving landscape of cyber threats. Whether for small businesses or large enterprises, the ASA 5500 provides the necessary tools to create a secure networking environment.
