What is Web Attack?
There are many ways hackers could target web applications (websites that allow you to interact with software through a browser) to steal confidential information and introduce malicious code and hijack your computer or device. These attacks exploit weaknesses http://neoerudition.net/the-biggest-list-of-antivirus-review-sites in components like web apps such as content management systems, web applications and web servers.
Web app attacks constitute an overwhelming portion of security threats. In the last decade attackers have developed their abilities to find and exploiting vulnerabilities that compromise security perimeters for applications. Attackers can bypass most defenses with techniques like botnets, phishing and social engineering.
A phishing attack consists of tricking victims into clicking an email link that contains malware. This malware is downloaded to the victim's PC and gives attackers access to systems or devices. Botnets are collections of compromised and infected devices, which attackers can use to launch DDoS attacks, spread malware, continue fraud in advertising, and much more.
Directory traversal attacks use the use of movement patterns to gain access to configuration files, files, databases, and other files on the website. In order to protect against this kind of attack requires proper input sanitization.
SQL injection attacks seek at the database that holds critical website and service information by injecting malicious codes that allow it to bypass and reveal information that it wouldn't normally disclose. Attackers can then execute commands to dump databases, and many other things.
Cross-site scripting (or XSS) attacks insert malicious code into a trusted site to hijack browsers of users. This allows attackers to steal session cookies and private information and impersonate users, alter content, and many more.
