Some common security errors
When it particularly comes to the security concern on the web, some of the common mistakes that web developers commit during the process include:
- XSS (Cross-site scripting): It is a threatening attack that allows the significant execution of the script available in your browser. This, in turn, can cause hijacking of user sessions and deface websites. Additionally, it can possibly introduce malicious worms. The major reason behind this error is inappropriate validation of data for user-supply.
- CSRF (Cross-Site Request Forgery): CSRF or XSRF particularly involves the attack of some malicious sites on visitors’ session that compels them to carry out a distinctive action on their site. This generally happens with those sites that people use frequently like Facebook and email portals. If your original website is susceptible to such attacks, then it can cause several malicious occurrences on behalf of the users. However, you can essentially protect your site from such malicious attack by using a single token for an individual user.
- SQL injection: It is yet another malicious attack on your site that significantly exploits validation of insufficient input and acquires access of the shell on your server of database.
