What is SQL Injection Attack and How It Affects Security

sql-injection-attackThere are many types of attacks and threats that can compromise our network security. Hackers can use very different methods to steal data or attempt to carry out their attacks. Today we are going to talk about what SQL injection attacks are. It is a type of attack that is based on existing vulnerabilities. Let’s talk about how this security threat acts.

What are SQL injection attacks?

When we talk about SQL injection attacks we refer to a method that takes advantage of errors that exist in web applications. They are basically vulnerabilities that allow a potential intruder to inject malicious code to carry out their attacks and compromise the security and privacy of users.

An SQL injection attack could be aimed at compromising web pages or databases . A hacker could manipulate, steal or delete information and data in these compromised websites or databases.

As we mentioned, SQL injection attacks are based on existing vulnerabilities . That is why it is vital to always keep the systems, devices and any software that we use correctly updated. In this way we can correct security errors that can be used by third parties to carry out their attacks. We need to always have the latest patches and updates.

For example, a cybercriminal could inject malicious SQL queries into the input field of a web. This way you could trick the site into executing commands and accessing its database. Logically an attack of this type can make the operation of the web not adequate. It can affect performance. However, it also affects privacy by stealing data and information, modifying or even deleting it.

It should be mentioned that it is known as SQL injection attack to any infiltration method without distinguishing between possible vulnerabilities. It is, in short, any moment in which invasive SQL code is injected into the legitimate one. It is a computer security problem that can have a spy character.

How to avoid SQL injection attacks

We have seen what an SQL injection attack is and how it acts. Now we are going to give a series of tips to avoid them. We already know that security is a fundamental factor and we need to always find a way to protect our devices and systems. That is why it is vital to keep certain recommendations in mind.

Keep in mind that in most cases SQL injection happens on websites. It does not therefore affect users’ devices. This makes security measures necessary by those responsible for those pages.

It is important that those responsible for websites or web applications have their services updated correctly . It is vital to correct the possible vulnerabilities and avoid that hackers can access the content.

It will also be necessary to have security tools . They can protect us from very diverse attacks such as SQL injection. There are add-ons that we can add to our site to avoid this problem.

In short, SQL injection attacks affect applications and web pages. Basically it consists of the introduction of malicious code that modifies the legitimate one and that aims to steal user data and obtain information from them. Regarding private users, we can do little to protect ourselves, since it depends mainly on the web pages that must be protected by those responsible for them.

Security and privacy are very important factors and you have to always take care of them. This makes it necessary to have certain security tools that we can use. All this must be applied regardless of the type of device or operating system we are using.
