Provides outbound and inbound load balancing, and provides multiple load balancing algorithms. When one of the lines is disconnected, all network packets will be automatically redirected to another normal line to ensure that the internal user network is smooth. When the line is restored, the packet It will be automatically assigned again.
Enterprises can set their own load balancing rules according to their needs, and network access can refer to the set rules to perform network traffic load balancing guidance. Algorithms include: automatic allocation, manual allocation, allocation by source IP, and allocation by destination IP.
Provide enterprises with the most complete defense-in-depth mechanism. Today's network attacks cannot only rely on a single point of defense but require complete defense-in-depth. Only by using different levels of defense technologies can companies reduce potential threats.
In addition to providing firewalls, intrusion detection systems (IPS), and anti-virus as the basis for enterprise information security protection, Hexiang NGS 5952HTG can strengthen the detection of malicious programs for traffic, web pages and emails, and analyze the correlation of different security mechanisms. , To play the role of defense in depth.
Web application firewall is a product that provides protection for Web server applications by implementing a series of security policies for HTTP/HTTPS.
WAF's job is to parse the web application layer data, perform multiple conversions of different encoding methods to restore the attack plaintext, combine the deformed characters and analyze it, which can be better than the combined attack from the web layer. Providing application layer rules WEB applications are usually customized. Traditional rules for known vulnerabilities are often not effective enough. WAF provides special application layer rules and has the ability to detect deformed attacks, such as detecting mixed attacks in SSL encrypted traffic
The enterprise already has a mail host, but the spam filtering performance is not good. You can use NGS 5952HTG as a mail gateway mode to make up for the insufficient functions of the original mail server, such as spam filtering and virus filtering.
After filtering viruses and advertising mail through NGS 5952HTG, the clean mail is sent to the mail host.
The system provides Clam AV anti-virus engine for free, which can detect more than millions of viruses, worms, and Trojan horse programs. It can automatically scan emails for viruses, automatically update virus files through the Internet every day, and provide virus mail search condition.
Administrators can set the processing methods of poisoned emails by themselves, including automatic deletion, storage of poisoned email extensions, and the subject of the poisoned email notification letter. The new generation UTM has a built-in Kabbah anti-virus engine for one year. Customers can purchase and continue to enjoy the Kaspersky anti-virus engine leader with the highest scanning rate and the strongest virus repair.
Any network behavior, no matter what kind of software the user runs, is roughly divided into the number of uploads and downloads (Connect Session), flow (Flow) and duration (Time) from the perspective of network packets, by detecting these The combination of the numbers, it is estimated that the user is using the Internet normally or has abnormal behavior.
When an abnormal behavior of internal users is discovered, the administrator can adopt a variety of strategies, such as blocking the Internet, immediately limiting its maximum bandwidth, enabling a collaborative defense mechanism to notify the switch to block it, or notifying the administrator.
Assist network administrators to control network traffic, effectively reduce corporate network congestion, and improve serviceability and bandwidth utilization.
With QoS (bandwidth management) function, the limited bandwidth can be allocated to all users.
The difference from the general bandwidth manager is that NGS 5952HTG not only provides maximum bandwidth and priority management, but also has the function of guaranteeing bandwidth. And it also has the design of personalized bandwidth management, which can set the bandwidth management for individual users.
If bandwidth management is used with personalized bandwidth management, the bandwidth reserved by the bandwidth management function can be redistributed to users under the enterprise, which can effectively prevent the phenomenon of bandwidth being monopolized by users.
Advanced Sandstorm can effectively detect unknown advanced malware attachments, such as common Microsoft, Word, Excel, Power Point or PDF; or targeted phishing emails, and even compressed files, such as ZIP and RAR.
Before scanning emails for Spam or Virus, Sandstorm Defense compares suspicious attachments, isolates problematic emails, and exposes potential malicious programs to avoid affecting users' email reception.
The built-in "cloud URL database" automatically classifies web pages. As long as the administrator prevents blocking of harmful URL networks, it can be easily controlled. There is no need to input website IP addresses, keywords... to block them one by one.
Randomly clicking on harmful URLs is the source of evil. The best way to prevent blocking is to prohibit the use of the Internet. If it cannot be completely prohibited, the URL database that is updated from time to time is the best protection mechanism.
Some employees of enterprises use the Internet during working hours to do non-work purposes, chatting is small, and leaking secrets is a big deal.
NGS 5952HTG can not only limit the user's authority to use related applications, but also record related online behaviors, including browsing web pages and sending and receiving emails. When a company leaks secrets, the information that has been preserved is the best evidence to be used as evidence in court.
Various network application software is not only difficult to manage, but also easily becomes the best channel for data leakage and virus attacks.
NGS 5952HTG has built-in multiple application management functions, including instant messaging, audio-visual services, file transfer, P2P software, remote control, browser, VOIP, online games, network protocols, etc., which can easily control the use of application software by employees Permission to protect corporate network security.
Provides flow meter on the WEB interface, and plots the historical status of the system into a chart, so that the administrator can easily grasp the current system operation status at any time.NGS 5952HTG provides system status chart (including CPU load chart, memory load chart, system load), network traffic chart (LAN traffic, WAN1~WAN13 traffic), and provides query conditions to quickly search the history of each traffic status.
Provides a variety of logs, such as log in/out log, system network settings, regulations and targets, network services, advanced protection, IPS, mail management, content logging, VPN, etc. and a detailed log search system.
It is used for debugging analysis, evaluation of system performance, and proof and tracing basis when it is illegally invaded.
Use IPSec, PPTP, L2TP, SSL VPN to securely connect between Site to Site, Point to Site and remote users.
Through these VPN mechanisms, it is convenient for users to connect to different devices from different locations, including home, external public information service stations, and the Internet, such as laptops, branch offices, business locations, mobile communication devices, or at home …Wait.
Among them, SSL VPN is currently the most important long-distance secure transmission connection between most enterprises, customers and partners.
IDC defines UTM information security hardware equipment as: it contains multiple security functions integrated into a single hardware device, which must include network firewall, network intrusion detection and defense, and gateway anti-virus. All functions on this device do not need to be fully utilized, but must be built-in, and individual components cannot be cut.
In order to test these devices, NSS Group clearly defined UTM devices as a single device with functions such as firewall, VPN, IDS/IPS, anti-virus, anti-spam, URL filtering, content filtering, etc. The detailed definitions are as follows:
* Firewall: Deployed at the network boundary, a powerful state NAT firewall is required.
* VPN: It is often deployed on the enterprise wide area network as a branch office network solution. Basically, it is necessary to be able to establish a small number of secure VPN channels.
* IDS/IPS: The firewall can only enforce policies. If the policy allows incoming HTTP traffic to the website server in the DMZ zone, the firewall cannot prevent hackers from damaging the target website server from the HTTP protocol. The IPS function will detect and block such intrusions that attempt to use the network boundary to break in, and prevent malicious network flows from reaching the server. The IDS function can detect intrusions and issue warnings, but it cannot block malicious traffic.
* Antivirus: The gateway antivirus filter can prevent inbound virus traffic on the network boundary, strengthen the computer desktop security, and block them before they reach the desktop. The solution can also prevent internal computers from being infected by viruses from outside the corporate network. .
* Anti-spam: Gateway anti-spam can mark incoming emails, allowing further processing by computer filtering solutions. The solution can prevent internal hosts from sending spam messages outside the enterprise.
* URL filtering: Using a continuously updated URL classification database, a set of gateway URL filtering solutions can prevent employees from accessing unpleasant or inappropriate websites from within the corporate network.
* Content filtering: Scan specific content of webpages and mail traffic. Gateway content filtering solutions can prevent unpleasant or inappropriate content from passing through or being sent out from the corporate network.
