According to IDC, there will be 1.9 billion PCs, 2.6 billion smart phones and more than 2 billion consumer electronic devices in 2020. Embedded devices and intelligent systems look at 25 billion units, far more than the first three. It is obvious that the development potential of the Internet of Things (IoT) is amazing. Under the new situation of "connected objects", it is safe to ensure that each other is connected in series. A crucial topic.
Text: In 2012, the nuclear power plant in southern Iran was operating without warning due to malicious attacks. Although the authorities of the country immediately stopped the spread of the disaster, it was enough for the countries to be vigilant. The network security needs should not only end in the enterprise data center, but also in the telecom equipment room and machinery. All networked devices, such as machine (M2M) and industrial applications, and home networks, may become intrusion points for cyber threats and must be protected. For example, if a flood gate is ineffective due to hacking, it may cause a major disaster and cause serious damage to people's lives and property.
In view of this, the design of a new generation of network security platform is no longer limited to the rising network traffic, but also echoes the general trend of “Internet everywhereâ€. On the one hand, it expands its reach into the telecom engine room along the path of the booming mobile communication. In the second aspect, it is necessary to comprehensively consider the attack defense requirements of various communication protocols. In addition to the generally visible Ethernet network, it also strengthens the monitoring and resolution capabilities for other communication networks such as ZigBee, Wi-Fi, and EtherCAT to meet M2M and Industrial network security needs.
"For example, the traditional network security platform based on 2U server, can you properly handle the traffic that breaks through 100 per second?" Liu Hongyi stressed that in view of the increasing demand for high-bandwidth and high-speed packet processing, the network security platform is absolutely It can't just be a simple server. It needs to be fully integrated with technologies such as switches and network processors (NPUs) to optimize packet processing efficiency. Therefore, switches and NPUs are no longer just communication media, or x86 computing systems. The supporting Add-on card should be deep into the core of the platform architecture.
In short, the new generation of network security platform needs to be smart, make good use of NPU to follow the packet rules and filter, and share the workload of the central processor greatly, so that the previous section has been checked for error-free traffic, and the latter paragraph does not need to be repeatedly inspected, directly Forward (Transfer), simplify packet processing, in order to cope with multiple growing network traffic.
The network security hardware platform needs to have high throughput capacity. Firstly, because the contents of the package are mostly large files of multimedia images, if the previous package is checked and confirmed to be safe, then the layer inspection can be avoided, so as to avoid the network. Road congestion; Secondly, the huge amount of data generated by M2M is beyond the imagination of everyone, so there is no need for change in the existing architecture.
Dedicated machine thinking and evolutionOn the other hand, when the network security platform begins to enter different application environments and carries different traffic loads, it must be more "specialized" than before. The so-called specialization not only ends with the difference in appearance, but also needs to be highly compatible with the network security software. In order to save customers the burden of integration; in addition, it is necessary to pass different certification tests, such as telecommunications NEBS Level 3, track application EN50155, etc., so that customers can directly obtain tickets for vertical application areas. Liu Hongyi added that in response to the key task orientation of M2M and industrial control, it is one of the necessary conditions for the network security platform to adapt to the harsh environment such as waterproof, dustproof, wide temperature and earthquake resistance.
In a nutshell, looking forward to the future, the network application environment is different, the traffic is mutated, and the dedicated network security platform will be relied on by customers. It not only looks unique, but also has multi-core integration technology, and needs to be tailored to meet specific application requirements. .
Taking Xinhan as an example, the new network security machine launched in 2013 will be classified according to different application requirements such as telecommunications, industrial control and high throughput. In the telecommunications segment, the ATCA blade server and rack server are NEBS Level 3 certified; in industrial control, the EN50155 certified in-vehicle system and the DIN-rail rail platform for the factory environment . As for the high-throughput solution, NEXCOM can tailor its network security platform to meet customers' needs, with different central processing units, NPUs and network switching chips.
The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
