The Cisco ASA5520-BUN-K9 firewall provides connectivity options of 4 Gigabit Ethernet ports and 1 Fast Ethernet Port. In addition, it also allows 750 IPsec VPN peers, Active/Active and Active/Standby high availability modes and provides a 3DES/AES license. Now, as a solution expert in network security, we recommend you utilize AES over 3DES in your network. AES is more efficient in security and slightly harder to crack when it comes to unwanted attacks.
Next, IPsec allows protection for Virtual Private Network IP traffic through methods of encryption. This should be a common feature sought after in any hardware firewall if plan of tunneling traffic from your VPN across a non-secure public extranet or the Internet.
Another notability feature set of this Cisco ASA 5520 firewall includes the high availability modes available to you for configuration. The main functionality of Active/Active mode allows all system requests to be load-balanced between the devices processing capacity. In the event of a failure, the secondary node takes over to ensure functionality is not lost. In Active/Standby, the standby functionality is not utilized until the Active node has failed. Meaning, no processing power is being utilized from the Standby node.
The Cisco ASA 5520 Adaptive Security Appliance delivers a wide range of security services with Active/Active high availability and Gigabit Ethernet connectivity for medium-sized enterprise networks, in a modular, high performance appliance. Using its four Gigabit Ethernet interfaces and support for up to 25 VLANs, businesses can easily deploy these security services into multiple zones within their network. The Cisco ASA 5520 Adaptive Security Appliance scales with businesses as their network security requirements grow, delivering solid investment protection. Businesses can extend their IPSec and SSL VPN capacity through multiple means to support a larger number of mobile workers, remote sites, and business partners. VPN capacity can be increased by taking advantage of the integrated VPN clustering and load-balancing capabilities of the Cisco ASA 5520 Adaptive Security Appliance, as well as more than doubling each platform's VPN capacity through the installation of a VPN upgrade license. The advanced application layer security and anti-x defenses provided by the Cisco ASA 5520 Adaptive Security Appliance can be extended by deploying a high performance Security Services Module. Using the optional security context capabilities of the Cisco ASA 5520 Adaptive Security Appliance, businesses can deploy up to 10 virtual firewalls within an appliance to enable compartmentalized control of security policies on a departmental level. This virtualization strengthens security and reduces overall management and support costs while consolidating multiple security devices into a single appliance.
