I believe you have heard of DoS attacks, DDoS attacks, and DRDoS attacks! DoS is short for Denial of Service and DDoS is short for Distributed Denial of Service and Distributed Denial of Service. DRDoS is short for Distributed Reflection Denial of Service, this is the meaning of Distributed Denial-of-Service. However, the most severe attack method in these three cases is DDoS. Although the DRDoS attack is a new attack method, it is only a deformation of DDoS attacks, the only difference is that

ARP defense: The above is a simple demonstration of ARP attacks. How can we defend against such attacks? You can install the

Defense Against database hit attacksHazards of credential stuffing According to the current test experience, credential stuffing is still a very common vulnerability type for Internet enterprises in China.Basic defense strategies In fact, there are still many solutions, but many of them can be bypassed in design. In general, the verification code policy is blocked more than a certain number of times. An

redirection very difficult. In TCP/IP implementation, the host has the following restrictions on receiving ICMP redirection packets: the new route must be direct, and the redirect packet must come from the current route to the target; the redirection package cannot notify the host to use its own route. The changed route must be an indirect route. Because of these restrictions, ICMP spoofing is actually difficult to implement. However, we can also take the initiative to find some other methods b

How can I attack others and make profits?Stored XSS Stored XSS is a storage-type XSS vulnerability. Because its attack code has been stored on the server or database, many victims are victims. Scenario 2: A.com can post an article. After I log on to a.com, I published an article in a.com, which contains malicious code. to save the article. At this time, Tom and Jack saw my published ar

If the tb UserData has been set, the base has a turret and cannot be added.If all checks pass, a new turret is created, placed on the base, and added to the turret array. Compile and run the task. After you touch the base, you can see that the turret is placed, and there are white circles around it to show the attack range, as shown in: References: 1.How To Make a Tower Defense Game http://www.raywenderlich.com/15

There have been articles on cross-site scripting attacks and defense on the Internet, but with the advancement of attack technology, the previous views and theories on cross-site scripting attacks cannot meet the current attack and defense needs, and due to this confusion in understanding cross-site scripting, as a result, many programs, including the current dynamic network, have the problem of loose filte

Program robustness and self-defense In fact, the robustness (robustness) of the program is a concern of all languages. Here we will focus on self-defense. 1. Black Box operations are required for Object-Oriented Because object-oriented requires that each part is independent from each other, each part must be strong enough to cope with input parameter irrationality. Although modern programming focu

DP [I] [J] indicates the damage caused by J slowdown in step I. We put the damage caused by a greedy strategy at the end, and the damage caused by sustained damage and deceleration at the front of I is the highest. Therefore, the damage in the first (I, j) is DP [I] [J] = max (DP [I-1] [J] + (J * z + T) * (max (0ll, i-1-j) * y, DP [I-1] [J-1] + (J-1) * z + T) * (I-j) * y ); The damage caused each time is: DP [I] [J] + (n-I) * (J * z + T) * (x + (I-j) * Y ). Take the maximum value, which is the m

Attacks and defense against abuse of permissions in the IOT age In addition to debugging on the android real machine, the permission Abuse Vulnerability has many other scenarios. It is particularly widely used in the IOT field. For example: A smart TV can be remotely debugged through the network, a monitoring system of a large rotating machine can be remotely controlled, a highway camera can be controlled to take photos, and a carrier device can be co

Is our click, drag and drop, touch screen operation was hijacked, and to operate the other transparent hidden interface. The principle is to use the transparent layer +iframe, using the CSS opacity and Z-index properties, to reach the transparent and above other interfaces, and then use the IFRAME to embed the hijacked page. It's not what he sees, it's not the interface he think

PrefaceThis time we will talk about how to achieve the effect of Nginx defense attack by simple configuration file.In fact, many times, all kinds of anti-attack ideas we understand, such as restricting IP Ah, filter attack string Ah, identify the attack fingerprint. But how to achieve it? With a daemon script? Using PHP to filter the bread layer? Or do you want to add a firewall directly? These are all defensive measures. However, this article will be

The cc attack, HTTP flood, is a low-cost attack (with just a few HTTP proxy servers), covert (small cc attacks typically do not cause network bottlenecks), difficult to defend (indistinguishable from normal access requests), and powerful (resulting in the same effects as DDoS traffic attacks). , the website can not be opened for a long time) and other characteristics known. Regular HTTP flood defense for JS bounce back, two requests to verify the whit
