The intelligence of DDoS attacks is tending to be intelligent

With the advent of various intelligent cyber-attack tools, it is possible for ordinary technology attackers to attack vulnerable computer network systems in a relatively short period of time. If the security personnel want to win in the cyber War of the invasion, they must first "TSE" to use the corresponding countermeasures to organize these attacks.

Current attack tool developers are using more advanced ideas and techniques to arm attack tools, and the features of attack tools are more difficult to discover than before. A considerable number of tools already have the characteristics of reverse detection, only dynamic behavior, and the variation of attack tools.

Anti-detection means that attackers increasingly use techniques with covert attack tools, making it more time-consuming for network administrators and network security experts to analyze new attack tools and understand new attacks.

Intelligent dynamic behavior refers to the current attack tools can adapt to the environment adaptively Select or predefined decision strategy path to change to their patterns and behavior, unlike earlier attack tools, only in a single determined sequence of execution of the attack steps.

The attack tool variation means that the attack tool has developed to rapidly change itself by upgrading or replacing a part of the tool, and then to launch a rapidly changing attack, and there will be many different forms of attack tool in each attack.

1 vulnerability discovery and utilization faster and faster

Security vulnerabilities are the most important factor in network security, security vulnerabilities are not the difference between the manufacturer and the operating system platform, he is ubiquitous in all operating systems and applications. The newly discovered operating system and network security vulnerabilities increase by one times a year, and network security administrators need to continually patch up the vulnerabilities with the latest patches. But attackers are often able to exploit these patches before they are released by the vendor.

2) The penetration rate of the firewall is getting higher

Configuring the firewall is still the main protective measure for enterprises and individuals to guard against network intruders. However, the attackers have been studying the techniques and means of attacking and evading firewalls. From the process they attack the firewall, there are probably two categories.

The first type of attack firewall is to detect which firewall system is installed on the target network, and to find out which services the firewall system allows to open, which is based on a firewall detection attack.

The second type of attack firewall method is to take address spoofing, TCP serial number attack and other techniques to bypass the firewall authentication mechanism, to attack the firewall and internal network.

3) The asymmetry of security threats is increasing

Security on the Internet is interdependent, and the likelihood that each Internet system is compromised depends on the security status of the other systems connected to the global Internet. As the level of attack technology progresses, attackers can easily exploit those insecure systems to launch destructive attacks on victims. As deployment automation and attack tool management techniques improve, the threat asymmetry will continue to increase.

4 The destruction of network infrastructure is getting bigger and larger

As users increasingly rely on networks to provide a variety of services to perform day-to-day business-related operations, attackers are increasingly damaging the network infrastructure that is critical to the Internet. The main means of attacks on these network infrastructures are distributed denial of service attacks, worm attacks, DNS attacks on Internet domain name systems, and attacks on routers. Although the router protection technology has already been formed, many users do not make full use of the router to provide encryption and authentication characteristics for the corresponding security protection.
