Attack Scenarios of Network Security

Attack Scenarios of Network Security

With the rise of network security as a serious issue in the industry, the main concern is not only about the attack vectors, but also the attack scenarios. Attack scenarios are very diverse in terms of network models and attack methods for various types of networks and types of network devices. Attack scenarios can be categorized into two groups, which include physical attack scenarios and IT security attacks. Physical attack scenarios are related to non-physical vulnerabilities, such as software vulnerabilities or hardware vulnerabilities, which are not related to the network environment, and do not affect the network performance or behavior. For example, a vulnerable user may use a proxy server to access the Internet and launch a distributed denial of service attack (DDOS attack) when accessing a network in a public network, which is not related to the network environment and affects the network performance and behavior.

Physical attack scenarios of network security are related to the network attack methods, such as the network attack method itself and the detection methods for the attacker. The network attack methods include physical attack and software/firmware attack, which do not affect the physical hardware (such as network nodes or physical security devices) of the network. The network attack methods can be categorized into two groups: physical attack and software/firmware attack (or attacks). The physical attack methods, such as the access vectors and attack targets, affect the physical hardware of network nodes or physical security devices, and may cause security issues in network networks. Therefore, network security usually deals with access vectors and attack targets.

The software/firmware attack methods involve the attacker to modify network applications via malicious network applications using the software/firmware, and the modified network applications are not affected by the network environment. For example, a malicious user may execute malicious network applications on a network device or on its host device, or may modify network application behaviors such as the network access method, a traffic priority, or an access path to launch a distributed denial of service (DDoS) attack.

The IT security attacks are related to the attacker directly modifying network applications; the IT security attacks may affect the physical hardware (such as network nodes or physical security devices) of the network environment. IT security attacks are classified into two types: network security and network intelligence attacks.

An unprecedentedly high throughput TCP/UDP accelerator

The TCP/UDP accelerator achieves more than two orders of magnitude in hardware capability. In the past, the TCP/UDP accelerator has been deployed as a standalone facility in servers and other TCP-enabled equipment. This time, the TCP accelerator is deployed in a distributed mode, in which it is implemented as a network card in the local access router in the access layer of the WAN. This design enables the TCP accelerator to perform faster than 1. 5 to 2 times in throughput, compared to the standalone facility.

In recent years, the TCP/UDP accelerator has been deployed as a network card in the local access router (LAR) in access layer of the packet processing in the WAN. This time, the TCP accelerator is adopted for the Internet Protocol (IP) packet forwarding as a network card in the access layer of the packet forwarding. To realize this, a distributed TCP accelerator architecture is proposed using a combination of the UDP accelerator and the TCP accelerator inside the access router to provide a high throughput. The performance metrics of this design are evaluated.

This article discusses the architecture and the performance, which includes the hardware/software architecture of the TCP/UDP accelerator embedded in the access router, the TCP/UDP accelerator hardware, the design of the TCP accelerator, the performance evaluation of the TCP accelerator.

The architecture of the TCP accelerator is shown in Figure 1. At the data source of the TCP/UDP accelerator, a TCP/UDP data packet is processed and sent to the TCP acceleration mechanism, which implements the TCP acceleration. At the TCP acceleration layer, the TCP acceleration software executes the TCP acceleration function and sends the TCP acceleration information, including TCP header information, ACK flags, etc. , to the TCP accelerator hardware. The UDP accelerator then sends the TCP acceleration information, including the TCP header information, ACK flags, etc. , to the UDP accelerator hardware. The UDP accelerator hardware converts the TCP/UDP accelerator to its hardware counterpart by means of dedicated processing. The TCP/UDP accelerator hardware can perform more than two orders of magnitude in hardware capability, compared with the standalone facility, according to the evaluation results.

Figure 1: Architecture of the TCP accelerator.

Figure 1 shows that the UDP accelerator hardware is implemented by a single chip that handles both the TCP acceleration and the UDP acceleration.

Intilop: A Pioneer in Full TCP Offload engines.

Article Title: Intilop: A Pioneer in Full TCP Offload engines | Network Security. Full Article Text: ‘I have seen this article in a magazine, it is an excellent summary of the recent advances in technology that is making TCP Full TCP Offload easier to obtain in Windows and Linux.

“What I want to show you here is what I mean by Full TCP Offload, and why I believe it’s the best way to prevent this kind of virus and attack. The techniques described here can prevent even a sophisticated attacker from achieving this. They all rely on a TCP Full Offload engine, and I should explain what a ‘Full Offload’ is.

“In a Full TCP Offload pipeline, the first step is to enable TCP Full Offload, which increases the overall throughput of the connection from the server to the client.

“After TCP Full Offload is enabled, the server sends a TCP Header Packet to the client, which contains the TCP Full Offload information. ” “After the TCP Header Packet is sent, the server and the client use an ICMP Echo Request to communicate the payload of their respective TCP Full Offload packets.

“In ICMP echo requests that send a payload to an ICMP echo reply, you can use the UDP ICMP protocol to forward the ICMP echo request. When ICMP echo requests are forwarded using an ICMP Echo Request, an ICMP Echo Reply is returned with the payload contained in the ICMP echo request payload.

“The ICMP Echo Request and ICMP echo reply are two separate, independent streams of data. ” “ICMP Echo Request is the input stream and ICMP Echo Reply is the output stream.

In modern, multi-tenant, cloud environments, it is fairly common for an administrator to be able to deploy a number of concurrent virtual servers. This can be achieved by configuring each virtual server as the host for another virtual server.
