Built-in Security Protection in All-Optical Gateways: AINOPOL Empowers Enterprise Parks to Defend Against DDoS and Email Virus Attacks

In the digital era, networks of enterprise parks and manufacturing factories face dual internal and external security threats. Externally, hackers and competitors launch SYN and UDP flood DDoS attacks, instantly exhausting external network bandwidth and paralyzing MES production systems, video conferencing and cloud desktops, which further force production lines to halt. Internally, staff may receive virus-laden attachments via corporate emails, download Trojans from the internet or share files through USB drives, easily triggering the lateral spread of ransomware within internal networks. Such viruses can encrypt R&D drawings and ERP order databases, causing huge losses including hundreds of thousands of ransom payments and leakage of business secrets.

Traditional park security construction modes have obvious flaws. Enterprises need to purchase multiple independent hardware devices separately such as firewalls, IPS intrusion prevention systems and antivirus gateways, leading to high costs on hardware procurement and annual license fees. In addition, separate operation and maintenance of various security management platforms often result in mutual shirking of responsibilities among different manufacturers once faults occur.

AINOPOL FTTN series integrated all-optical OLT gateways come with a full set of built-in hardware security protection modules. No additional security hardware is required. They can comprehensively defend against DDoS flood attacks, email and file ransomware, internal ARP attacks and cross-site data theft in one stop, fully meeting the core security protection demands of industrial parks and factories.

I. Four Core Security Construction Pain Points of Traditional Park Networks

Ordinary Routers Lack Hardware DDoS Cleaning Capabilities, Leaving Networks Vulnerable to Full-Scale Paralysis

Most small and medium-sized factories and industrial parks only adopt household or entry-level routers as external network exits without independent hardware traffic cleaning modules. When hit by DDoS flood attacks, abnormal traffic will occupy all external bandwidth in an instant, causing video conference freezes, disconnection of MES machine tool industrial control systems and suspension of all office work. A single attack may lead to production halt losses worth tens of thousands of yuan. Moreover, traditional software firewalls have insufficient computing power and fail to effectively block 100G-level attacks.

Lack of Full-Link Virus Detection for Emails and Internal Files Leads to Rampant Ransomware

Traditional networks are not equipped with full-range internal network antivirus gateways, relying merely on local antivirus software installed on employee terminals for defense. Viruses can spread freely via corporate email attachments, web downloads, file sharing among office PCs and USB disk file transfers. Once ransomware invades the network and spreads laterally to encrypt core servers, enterprises will be unable to recover drawings and customer order data and have to pay high ransoms.

Absence of Hardware VLAN Isolation Between Internal and External Networks Risks Confidential Data Leakage by Visitors

Office Wi-Fi, guest networks, R&D and production networks as well as security monitoring systems share the same network without logical hardware isolation. External visitors who access the network can scan internal servers, posing great risks of leakage of R&D drawings and core production technologies. Meanwhile, frequent internal ARP spoofing and DOS attacks severely undermine the stable operation of production systems.

Separate Procurement of Security Hardware Results in High Investment and Fragmented O&M Work

Enterprises need to purchase firewalls, IPS systems and antivirus gateways separately, which involves high hardware costs and continuous annual fees for updating virus databases and intrusion signature libraries. Configurations on multiple independent security platforms double the workload of IT staff. In case of network attacks or virus outbreaks, disputes among different suppliers greatly delay fault handling efficiency.

II. Full-Range Built-in Security Protection of AINOPOL Integrated All-Optical Gateways

Equipped with independent dedicated hardware security processing chips, AINOPOL integrated OLT gateways have all protection functions built-in with lifelong free upgrades. Enterprises do not need to purchase extra security devices. The gateways fully cover four core security scenarios: DDoS defense, email virus interception, internal network protection and cross-site encrypted transmission.

Hardware-Level DDoS Traffic Cleaning Blocks Various Flood Attacks

The built-in independent hardware traffic cleaning module can identify mainstream attack packets including SYN Flood, UDP Flood, ICMP Flood and CC attacks. Malicious traffic is discarded directly at the hardware level without entering enterprise internal networks, ensuring stable bandwidth for key services such as MES industrial control, video conferencing and cloud desktops. Users can customize attack thresholds. The system will automatically block malicious IP addresses and send alerts via SMS or mobile apps once attacks are detected, delivering stable defense against 100G-level traffic attacks.

AV Antivirus Engine Blocks Email Ransomware Throughout the Transmission Chain

It is embedded with a virus signature database containing over 200,000 virus types with lifelong free automatic cloud updates, covering ransomware, worms, spyware and macro viruses. Full-traffic virus scanning is realized for all data flows including corporate email attachments, web downloads, internal PC file transfers and USB disk data uploads. Detected viruses will be blocked immediately with attack logs recorded, fundamentally stopping the lateral spread of viruses within internal networks. The system is specially optimized to fight virus transmission via corporate emails.

Seven-Layer IPS Intrusion Prevention System Provides Bidirectional Internal and External Network Protection

Supported by a database of more than 5,000 attack signatures, it conducts L7 in-depth traffic detection to intercept SQL injection, port scanning, internal ARP spoofing and DOS attacks. It defends against both external hacker infiltration and internal terminal attacks, distinguishing legitimate industrial control traffic from malicious attacks without interfering with real-time machine tool instructions and video conference data streams.

Multi-Layer Network Isolation and Fine-Grained Access Control

Hardware VLAN hard isolation divides the whole network into four independent network segments: guest Wi-Fi network, general office network, R&D & production network and security monitoring network. Cross-segment access is blocked by default. It also supports access control based on five-tuple rules (MAC, IP, port, etc.), Portal guest account authentication, black and white lists covering over 3,000 URLs and management of more than 3,000 mainstream applications. Managers can set time-based access restrictions on entertainment software such as short-video platforms and stock trading apps to prevent bandwidth waste and internal data leakage during working hours.

Dual Hardware Encryption Prevents Cross-Site Data Theft

AES hardware encryption is applied to PON optical links, and IPsec hardware encrypted tunnels are adopted for SD-WAN cross-site networking. Production process drawings and order data transmitted between headquarters and branch factories are fully encrypted, avoiding data hijacking and tampering during public network transmission. Complete security audit logs are stored locally for a long time to meet the compliance audit requirements of Cybersecurity Classified Protection Level 2.0.

III. Six Core Practical Advantages of Integrated Built-in Security Solutions

Integrated All-Round Security Functions Cut Costs on Independent Security Hardware

One integrated OLT gateway integrates optical access, routing, wireless network, VOIP and comprehensive security protection functions. There is no need to purchase firewalls, IPS systems and antivirus gateways separately, reducing one-time investment on security hardware by 80% and eliminating annual fees for security function authorization.

Independent Dedicated Security Chips Ensure Protection Without Occupying Service Forwarding Computing Resources

Traffic cleaning and virus scanning are processed independently by dedicated hardware chips without consuming gateway service forwarding performance. It ensures zero latency and smooth operation under high-concurrency scenarios such as 4K monitoring, industrial big data transmission and multi-terminal video conferencing, delivering better performance than traditional software-based security solutions.

Full-Chain Email Virus Interception Avoids Losses Caused by Ransomware Encryption

End-to-end virus detection covering external email access and internal file transmission accurately intercepts email macro viruses and ransomware attachments, protecting core servers running ERP systems and storing R&D drawings, so as to prevent enterprises from paying high ransoms and suffering permanent loss of core business data.

Hard Isolation of R&D Networks Prevents Unauthorized Access to Core Confidential Information

Guest network segments are completely isolated from R&D and production networks both physically and logically. Combined with MAC address whitelist access control, only authorized R&D devices can connect to drawing servers, forming dual protection to stop unauthorized access to technical data by external visitors and ordinary employees.

Batch Deployment of Security Strategies via EAAS Cloud Platform Realizes Unified Protection Across Multiple Sites

The cloud platform supports batch configuration of DDoS defense thresholds, virus interception rules and website black-and-white lists, enabling all branch factories and industrial parks to follow unified security standards without manual on-site configuration by engineers.

Permanent Storage of Complete Security Logs Facilitates Smooth Classified Protection Evaluation

Long-term local storage of records including network attack interception logs, virus warning logs and internet behavior logs exempts enterprises from purchasing additional audit devices for cybersecurity classified protection assessment, lowering supporting compliance investment.

Traditional enterprises and manufacturing factories usually procure firewalls, IPS systems and antivirus gateways separately, which leads to high hardware costs and annual service fees as well as complicated multi-platform operation and maintenance. Networks without sufficient protection are vulnerable to external DDoS traffic attacks and internal ransomware spread via emails, putting core data such as R&D drawings and order information at risks of encryption loss and business leakage.

AINOPOL integrated all-optical OLT gateways embed a full set of hardware security modules, realizing six core capabilities in one solution: hardware-based DDoS traffic cleaning, email & file virus interception, seven-layer intrusion prevention, multi-network-segment hard isolation, encrypted cross-site transmission and security audit.
