Features

Robust Design Powers SMB/SB Networks
ZyXEL ES-1528 comes with 24 Fast Ethernet copper ports plus four Gigabit uplinks (two 1000Base-T ports and two SFP slots) that fire up the non-blocking connection power to 12.8Gbps on SMB/SB networks, and its multi-function design fits into copper or fiber networks easily. By utilizing 4G uplinks and port aggregation, bandwidth on critical paths can be expanded flexibly by merging multiple traffic pipelines into a logical one to dramatically improve network stability.

ExtraSmartTM- Evolution New Smart Power
While many legacy Web Smart switches improve manageability, complexity is still a challenge. For most SMBs, inadequate IT expertise and complicated configurations are the major obstacles to overcome before getting connected. Powered by the newest hardware platform with smart ACL technology, "Auto DoS Attack Prevention" and "Auto VoIP" provides hassle-free operations required by a network with strict security protection and VoIP-friendliness.
In addition, the ZyXEL ES-1528 comes with a streamlined and intuitive Web-GUI for features demanded by SMB; such as 802.1Q VLAN, 802.1p traffic priority and static port aggregation. Requiring no awkward configurations or bulky user guide, the ES-1528 provides valuable features and convenience for SMBs.

Extra Secure - Auto DoS Attack Prevention
ZyXEL is highly aware that network security is a top priority for SMBs and have therefore enable the ES-1528/ES1552 to effectively combat DoS attacks. Security is the top priority for SMB/SB networks. Equipped with Auto DoS Attack Prevention, the ES-1528 is capable of fighting against ubiquitous DoS attacks. A few mouse clicks is all it takes to initiate protection, handling the once-complicated ACL setting and dramatically reducing operational issues. Operating efforts dramatically. ES-1528 supports 802.1Q VLAN for traffic isolation, as well as Static MAC forwarding and dynamic ARP to establish a strictly protected network.

Extra QoS – Auto VoIP Optimization
VoIP is a key to differentiate business competitiveness. It usually requires IT expertise to optimize a network for VoIP applications. With the emergence of the "Auto VoIP", however, the ES-1528 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 like four priority queues and a WFQ scheduling algorithm allows users to optimize network bandwidth usage and Quality of Services. In terms of bandwidth management, users can choose from several options and pick the most appropriate with just a mouse click.

Auto DoS Attack Prevention
Denial of Service (DoS) attacks try to disable a device or network so users no longer have access to network resources. Auto DoS Attack Prevention module matches attack types in switches and prevent network outage
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.
