The concept and characteristics of network security grid are simple and popular

Network security grid is the current

Network security

One of the hottest terms in the field , But many people don't know much about network security grid , Today, we will give you a brief introduction to the concept and characteristics of network security grid .

Network security grid concept

Network security grid is a security architecture method or strategy , Rather than a well-defined architecture or standardized technical approach , It's not a product , Its purpose is to find new ways to deal with the security challenges brought by the evolving business system and the evolution of network environment , Provide more powerful protection than traditional physical boundaries 、 More flexible and scalable security capabilities .

Network security grid features

1、 Common integration framework . Network security grid provides a general integration framework and method , The implementation is similar to “ Lego ” Flexible thinking 、 Can be combined 、 Scalable security architecture . Support the arrangement and collaboration of various interoperable security services through standardized tools , So as to realize the efficient integration of widely distributed different security services , Establish a cooperative security ecosystem to protect local people 、 Digital assets in the data center and cloud , And based on data analysis 、 The aggregation of intelligence support and strategy management capabilities forms a stronger overall security defense and response processing capability .

2、 Distributed network architecture . The network security grid takes advantage of “ grid ” Decentralization of 、 Peer to peer collaboration 、 Flexible structure 、 Reliable connection 、 Strong expansibility and other advantages , No longer focus on building around all devices or nodes “ A single ” The border , Instead, smaller... Are created around each access point 、 Separate boundaries . By establishing as many security boundaries as access points , Ensure that users with widely distributed physical locations can access safely anytime and anywhere , In line with the zero trust network “ Differential segment ” requirement , It makes it more difficult for cyber criminals and hackers to use the whole network . meanwhile , Logically, the relationship between subject and object in the network is point-to-point direct connection , No need to focus on specific physical network deployment , It can simplify the security configuration and automatically adapt to the dynamic changes of the network .

3、 Centralized management and decentralized execution . It is different from the traditional gateway centralized access control , Network security grid adopts centralized policy arrangement and authority management , Policy based distributed execution , Distribute network security control capabilities to more parts of the network , Bring security measures closer to assets that need to be protected , One side , It is beneficial to eliminate the blind spot of safety control , Alleviate the performance processing bottleneck of traditional centralized security control , Adapt to the needs of decentralized development of user terminals and organizational services ; On the other hand , It is conducive to the overall security threat analysis , Form a more consistent security posture , So as to achieve more accurate security control and faster response disposal .

4、 Define security boundaries around identity . In the current network protocol , The lack of identity elements has brought many security problems , Physics  IP  The relevance of address to people and terminals is getting weaker and weaker , Result in address based 、 Traffic 、 Log security detection and threat analysis technology is difficult to achieve threat research and judgment against people ; Traditional boundary access control technology based on network protocol field feature detection , It also makes identity based access impossible . Because cyber threats are essentially human threats , Therefore, it is difficult to achieve accurate and efficient security threat disposal . Network security grid continues the idea of zero trust network , Define network boundaries with identity , Make identity the basis of threat assessment and security control .
