Robust System Design
ZyXEL GS-1524 are 24-port L2 Gigabit switch with advanced Web-based management support, and it's specially designed for SB/Enterprise networks where extra bandwidth and advanced QoS or security features are required. To cope with the diverse requirements of SB/Enterprise businesses, the ZyXEL GS-1524 Web-managed switch comes with 20 Gigabit copper ports plus 4 dual-personality (RJ-45/SFP) Gigabit ports to provide 48 Gbps of non-blocking connectivity for SB/SMB networks. With the flexible multi-function design, GS-1524 fits any network with very little effort.
Evolution New Managed Power
While many legacy Web-based Smart switches improve manageability, configuration complexity is still an issue; for most SB/Enterprise, inadequate IT expertise and complicated configuration are the major concerns to overcome. Powered by the next-generation hardware platform with a content-aware engine, ZyXEL GS-1524 delivers stress-free networking. In addition, the streamlined and intuitive Web-GUI makes GS-1524 even easier to configure to slash the efforts needed.
Auto DoS Attack Prevention
Security is becoming increasingly important in SB/Enterprise networks. Equipped with Auto DoS Attack Prevention, the GS-1524 is capable of protection against ubiquitous DoS attacks. A few mouse clicks are all it takes to initiate the protection, complete the once-complicated ACL setting and reduce operating efforts dramatically. The GS-1524 supports 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and dynamic ARP to establish a strictly protected network.
Auto VoIP Optimization
Migration to VoIP is the key to differentiate business competitiveness. It usually requires IT expertise to optimize a network for VoIP applications. With emergence of the "Auto VoIP" feature, however, the GS-1524 can identify VoIP packet patterns and grant the highest priority to establish a VoIP-friendly communication automatically. "Auto VoIP" offers IP telephony without configuration headaches; features such as four priority queues and the WRR (Weighted Round Robin) scheduling algorithm are usually deployed on enterprise networks, allowing users to optimize network bandwidth usage and implement QoS (quality of service). In terms of bandwidth management and switch interconnections, users can choose from several options and pick the most appropriate with just a mouse click.

Types of DoS Attacks can be prevented
Land Attacks These attacks result from sending a specially crafted packet to a machine where the source host IP address is the same as the destination host IP address. The system attempts to reply to itself, resulting in system lockup.
Blat Attack These switch result from sending a specially crafted packet to a machine where the source host port is the same as the destination host port. The system attempts to reply to itself, resulting in system lockup.
SYNFIN Scans SYNchronization (SYN, ACKnowledgement (ACK) and FINish (FIN) packets are used to initiate, acknowledge and conclude TCP/IP communication sessions. The following scans exploit weakness in the TCP/IP specification and try to illicit a response from a host to identify ports for an attack:
Scan SYNFIN SYN and FIN bits are set in the packet
Xmascan TCP sequence number is zero and the FIN, URG and PSH bits are set
NULL scan TCP sequence number is zero and all control bits are zeros
SYN with port ‹1024 SYN packets with source port less than 1024.
Smurf Attacks This attack uses Internet Control Message Protocol (ICMP) echo requests packets (pings) to cause network congestion or outrages.
Ping Flooding This attack floods the target network with ICMP packets.
SYN/SYN-ACK Flooding This attack floods the target network with SYN or SYN/ACK packets.
