Nowadays, many operators have a headache for abnormal traffic attack, which is a serious challenge in the telecom field. Telecom operators should construct the prevention system of abnormal flow. The prevention work is an important work within the telecom operators, and it needs the support of the Government and the cooperation of the industry.
Security challenges for IP networks
The first of the security challenges that IP networks are facing is massive traffic attacks. The scale of attack tr
the most basic level, DDoS attacks are a vain attempt to make a machine or a network resource unavailable to the policy user. Although the methods, motives and policies of DDoS attacks are different, such incursions generally include the service of one or more persons attempting to suspend or suspend the connection between the host and the Internet temporarily or indefinitely.
In general, this is done through the collaboration of a distributed botnet
The Shellshock vulnerability is out of control. Yahoo! and WinZip
Security researcher Jonathan Hall recently claimed to have discovered a botnet built by a Romanian hacker and used the Shellshock vulnerability to control the servers of a large number of well-known Internet companies, including the official website of Yahoo and the compression tool software WinZip.
Jonathan Hall recently released a Yahoo Server Vulnerability Report, revealing that Yah
Docker Web security experts have discovered a new IoT zombie network that uses Linux.proxym malware and is trying to attack the site.
Linux.proxym is a Linux malware that creates a proxy network on infected devices through a SOCKS proxy server that forwards malicious traffic and masks its true origins.
According to Dr. Web, Linux.proxym was first discovered in February this year, its activities peaked in late May, and the number of devices infecting Linux.proxym in July has reached 10,000 unit
Generally, hackers like to scan vulnerabilities everywhere and insert malicious code into the "bot grabbing" method to organize botnets and launch DoS attacks.
However, security company Imperva found that a "honeypot system" consisting of up to 300 Web servers was recently hacked, and the servers were reconfigured and attacked by Google search.
The bandwidth of Web servers is usually quite large. If a certain scale is formed, a considerable amount of attack traffic can be formed, and one server
their own DNS, which means that all of the following DNS requests can be directed to the DNS server we set up ourselves, which is useful for us to understand the details of the internal network. So we set up a DNS server of our own and opened the log function of the DNS request to record the details of all requests. We have approximately control over the DNS point of 20 routers and are successfully redirected to our own servers.The rest is a simple analysis of the data, before which we can make
This article summarizes some of the strange cc control servers I've seen in my safe work. The design method of the controller server and the corresponding detection method, in each Cc Control service first introduces the Black Hat part is the CC server design method for the different purposes, and then introduces the white hat part is related detection methods , let's have a look at the western set. There's a part of the white hat part of the detection method that requires some data and statisti
, and the attacker can forge the source IP address in the package so that the attacker is not blocked by the packets returned by the server. As you can see, this is a fairly serious issue in the TCP/IP protocol. Filtering packets through a firewall policy can prevent DDOS attacks to some extent.At the moment, the CC attack is mainly for the WEB application to compare the consumption of resources where the crazy request, for example, the search function in the forum, if not restricted, let people

It can be seen that this is a serious problem in the TCP/IP protocol. Data packets are filtered through firewall policy audit to prevent DDOS attacks to a certain extent.

Although it is more primitive in some aspects, it also has more advanced parts, to some extent, it can be used as something in the same system.
Many fashionable followers in the IT industry may be shocked by the fact that this has been pointed out. In fact, the oldest example of successful implementation of cloud computing techn

Unity technology was the first technology used by my students to participate in the domestic competition. As a mentor, I felt that this technology was very powerful and powerful across-platform, with the ability to deploy multiple places at a time, it's easy to get started. It's a game development artifact!
At that time, I was still working hard on xNa Technology (Microsoft's game development language) and thus set foot on the road to studying unity engine development. (At that time, it was stil

I remember that the life of a common Botnet is 10, that of a hat-wearing Botnet is 10 + 10, that of a tie-board Botnet is 40 + 10, that of a pea is 1, and that of a watermelon is 4, however, the comm

Of course, a bad program may also cause the exit information of the child process to be stuck in the kernel (the parent process does not call the wait function for the child process). In this case, sub-processes become zombie processes. When a large number of zombie processes accumulate, the memory space will be occupied.

You may ask: "What is a botnet ?" A botnet is a jargon term for a collection of software robots, or bots, which run autonomously and automatically. they run on groups of "zombie" computers controlled remotely by crackers. this can also refer to the network of computers using distributed computing software. while the term
How can we defend against these botnets? The detailed method is as follows:Start planting five mushrooms and street lamp flowers. First, light up the road on the right side to see where the first botnet came from, and then immediately put potato mines on the left to deal with the first botnet, then, let's see where the second botnet came from and plant high n
