Many people don’t realise this but a website owned by you is actually a very valuable item. Sure the value of websites differ for various reasons such as age and traffic, but regardless how small your website is, it still has some form of value. This perceived value is why hackers keep trying to infiltrate your website and use it to their advantage.
Whether you are a big ecommerce company or a blogger in your room, you cannot let the hackers win. And an effective step towards ensuring hackers can’t wreak havoc on your website is identifying and blocking the following vulnerabilities;
Cross Site Scripting (XSS)
This is a vulnerability in web applications that an attacker can exploit by using application codes to gain access to your database content or simply corrupt it. If a hacker gains access to your database, he/she can create false data, read stored data, or delete them. Hackers taking advantage of this vulnerability is quite rampant and something you should actively guard against.
Compromised Authentication and Session Management
Simply put, this vulnerability makes a user ID vulnerable to hijacking. If a hacker succeeds at this, he/she can hijack a session and assume the identity of the attacked user. This is why it’s important to secure session identifiers and authentication credentials at all times.
Insecure Direct Object References
This vulnerability exposes internal implementation object references. What constitutes an internal implementation object are database records and keys, files, and directories. Hackers can actually gain access to a user's personal data in the event an application exposes in a URL a reference to one of the aforementioned objects.
This is more of an umbrella term for several types of vulnerabilities. But what all the vulnerabilities have in common is a mistake on the part of a web user to properly configure security settings of a web application. A single security misconfiguration can give a hacker access to all sorts of features and private data that in the wrong hands can lead to a catastrophic system compromise.
Cross-Site Request Forgery (CSRF)
CSRF can be described as a malicious attack that misleads a user to perform an action he/she didn't actually intend to. The hack is usually executed by a third-party website sending to a web application a request that a user who already has authentication will unknowingly accept. This will provide the hacker access to the web application via the oblivious user’s authenticated browser. Common targets for such vulnerability exploitations include social media and online banking.
Now that you know what vulnerabilities to fix, secure yourself by performing a security audit and responding as necessary.
