vpn security protocols

addition, the widespread use of IPsec will make the work of the Information Security Department more difficult, because they can no longer use the firewall for encrypted traffic, the firewall is invalid ). As for Layer 2 secure Ethernet, we all know that there are many ARP problems in IPv4, among which it can maliciously redirect traffic. IPv6 also has a very similar problem, but the name has changed: NDPNeighbor Discovery Protocol) poisoning, rather

that the Redis client communicates with Redis, and the communication protocol specifies the format of the command and return values. Understanding the Redis communication protocol not only allows you to understand the format of the AoF file and the contents of the master database to be sent from the database during master-slave replication, but also to develop your own Redis client (although there are corresponding Redis clients in almost all common languages). There is really not a lot of oppo

When you deploy IPv6 in a WAN, an IPv6 firewall is also deployed. This article introduces some security issues caused by IPv6 and the problems that IT professionals should consider when deploying and operating IPv6 firewalls. Introduce IPv6 Firewall The first line of defense for most enterprise networks is a firewall, which is used to defend against public Internet attacks and restrict access to the public Internet of local users. After IPv6 is deploy

Some of our commonly used network applications, such as e-commerce, are implemented at the network application layer. So how can we ensure security in the application layer protocol? In this regard, we will mainly discuss the SET protocol. First, let's take a look at the security protocol environment on the Internet. It is an important issue for e-commerce to handle e-commerce on the Internet and ensure the

Can you help me understand the differences between WPA2 and Cisco LEAP security protocols? Which one is better, more convenient, or safer? Cisco's LEAP (lightweight Extensible Authentication Protocol) is a variant prior to the approval of a proprietary IEEE 802.1X port access protocol standard. 802.1X is a framework that allows an identity recognition server to verify the certificate of the wireless user be

Supporting Demo Video: http://edu.51cto.com/course/course_id-485-page-2.html In many cases, applications with asymmetric encryption are not limited to servers, but also need to be used on network devices, such as SSH, the certificate is the most typical application of asymmetric encryption. It is particularly famous for its IPsec-based VPN applications, such: certificates can be used when configuring VPN b

httpd, we run the make command after the end, go into the 07_httpd folder to view, found that there is no generation httpd this file, detailed see three:Figure three Questions oneWorkaround: Run the make command again to get the prompt "can ' t open output file. /bin/httpd ", you know, in our current 07_HTTPD folder in the parent directory WS does not exist in the Bin folder, so the command is not allowed to enter the WS/BIN/HTTPD path, thus, We chose to use mkdir, the command that created the

Today, many SaaS and PAAs (Platform as a Service) vendors and developer fanatics have adopted cloud computing. In addition, some companies have expressed great interest in their virtualization projects, but have not yet formed a wave of implementation. It's not surprising, actually. Last year, cloud computing was not even in the top 10 list of Gartner's technology. Cohesiveft's CTO, Patrick Kerpan, says: Security is a barrier to the implementation of

upgrade from one wireless technology to another without replacing the hardware. A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server in DMZ (or in its own network segment) to handle wireless connection, VPN gateway requirements, and firewall information, and enable or disable the wireless network segment. However, by adding a virtu

reasonable, avoiding the cost of 802.1x encryption for virtual private network connections. The weakness of this method includes the high price. purchasing new machines can only meet the needs of new wireless LAN subnets, without changing hardware, it is difficult to upgrade from one wireless access technology to another. A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server i
