10g WAF defends Web Website Security (1)

With the rapid development of popular technologies such as big data, mobile Internet, and online video, this makes it necessary for network security devices to conduct more in-depth and comprehensive analysis of traffic, to solve the new security challenges brought about by the increase in bandwidth, and the network security has truly entered the 10G era.

Web security threats and defense in a 10-Gigabit Network Environment

In the network age of 10 Gigabit network, security is facing a huge challenge in performance. from low-end protection to high-end core protection, from access to convergence, from data centers to man, high-performance devices are required to ensure network security.

Currently, the main Web security threats include: SQL Injection, XSS attacks, malicious scanning, CRSF Cross-Site Request Forgery, DoS attacks, webpage Trojans, phishing, backdoor, worm attacks, Cookie tampering, and website leeching.

Among them, SQL injection and XSS attacks are the two most common and widely used Web security threats that pose the most serious harm.

In addition, CRSF Cross-Site Request Forgery, malicious scanning, website phishing and other Web attacks and protection are also attracting more and more attention in the industry.

In the face of so many Web security threats, what protection measures do we need? Is traditional protection methods still feasible?

Firewalls, anti-virus, and IDS/IPS are all widely used traditional Web security protection measures, especially the deployment of firewalls, blocking most attacks from the network layer, however, in the face of the increasingly complex Web security threats, especially the Web security problems in the 10-Gigabit network environment, it seems that there is not enough balance in mind to identify and block the popular Web Application Layer attacks.

The anti-virus system deployed at the gateway/Web server can effectively detect and protect viruses. However, it cannot identify malicious code in Web pages, that is, webpage Trojans. Because the webpage Trojan is usually a Normal script in the webpage program, it is only possible to download harmful programs or steal the privacy of the victim during execution. Likewise, anti-virus systems are more difficult to identify vulnerabilities in applications.

IDS/IPS, as a beneficial supplement to the firewall, enhance the Web security defense capability. However, IDS/IPS requires the construction of attack feature libraries in advance to match network data, and the technology itself has certain limitations.

Unlike traditional firewalls and IDS/IPS, WAFWeb Application Firewall and Web Application Firewall work at the Application layer and have inherent technical advantages in Web Application protection.
