Web Security Issues and Solutions

Web Applications


Once you find the Web security issues and solutions resource, you may want something to protect against all the cyber threats on the Internet. Studies say there’s released at least one million cyber threats per day.

Common Web Security Issues and Solutions

We are giving at least five vulnerabilities which trigger problems and solutions to web security. It is important to figure out what happens when there are bugs with your website. Therefore you have to consider these various situations:

Cross Site Scripting (XSS)

This is another type of vulnerability to injection that could result in a failure to sanitize. A hacker sets the JavaScript tags for your web application on entry. When this data is returned unsanitized to the user, it will be carried out by the user’s browser. It can be as simple as creating a connection and persuading a user to click on it, or it could be a much more sinister matter. The script runs on page load, and can be used to post the cookies to the hacker, for example.

Injection Mistakes

If you want a smooth filter of untrusted data, defects in injections need to be avoided at all costs. An injection vulnerability will allow you to transfer unfiltered data to the SQL server, browser, LDAP (LDAP injection) server, or anywhere else. A hacker can use those website layers to insert commands. That can lead to data loss and hacking of your own website. It can potentially infect other websites too.

Outdated Security Configurations

The professional security staff on the website will always ensure that the security settings such as passwords and authentications are personalised. Many people may still be human to miss out on important things in their work. Concrete scenarios include:

  • They let the application run at production with debug allowed.
  • They didn’t change passwords or default keys.
  • They also left the server allowed directory page, which leaks valuable information.
  • They allow for excessive machine-run services.
  • They ran an outdated software (think of plugins in WordPress, old PhpMyAdmin).
  • They haven’t corrected those pop-up notices on information about mistakes.

A Lost Function Level Access Control

Failure to issue an authorisation can also interrupt your website. It means that no proper authorization was performed when a function is called on the server. Often times, website developers depend on the fact that the UI was created from the server side. They think that the client can not access the functionality which is not provided by the server. It’s not as easy as they thought, as a hacker can always make fake requests to the “hidden” api, and it won’t be stopped by the fact that the UI doesn’t make this feature easily accessible. Nothing can deter an attacker from finding and abussing this capability if there is no authorisation.

Exposing Sensitive Data

A website security staff is a huge failure-not to encrypt and not secure your sensitive data. Data (such as credit card details) and user passwords should never move or be stored unencrypted, and always hash passwords. And while it goes without saying that the URLs should not fly with session IDs and sensitive data. Sensitive cookies should also have a safe flag on them, this is very critical and can not be over-emphasised.

Built for Web Security Issues & Solutions

Fixhackedwebsite gives business the most powerful tools. A Web Application Firewall (WAF) supplied over a Secure Content Delivery Network ( CDN) is the web protection and solutions tool. It is a fully capable website security checking tool from certified security analysts’ Cyber Security Operation Center (CSOC) staffed around the clock and powered by a Security Information and Event Management (SIEM) that leverages data from more than 85 million endpoints to detect and mitigate threats before they happen.
