SQL Injection: How to Avoid It and Protect Your Systems

With the evolution of computer technologies, the population has become increasingly connected, but there are complications, such as SQL Injection. Do you know it? In this article, we will explain what it is and how to protect yourself.

SQL Injection: How to Prevent it and Protect Your System?

SQL stands for Structured Query Language. This is a programming language to use the relational database in an uncomplicated and unified way.

SQL Injection is a type of digital attack based on SQL manipulation, as this is the way programs exchange information with databases, and most manufacturers use this software on PC and laptops.

A SQL attack happens when the attacker can place or modify queries that are sent to the relational database. This action works because there is trust in the arbitrary data that is shown to the user, as there is a context in the data made available.

SQL Injection via the Login Screen

This form of SQL injection is an attack option that takes place when the user tries to log in; the attacker creates a fake form that files your input data anywhere.

Because it is simple manipulation, it is difficult to identify, only small changes in the page or its internet address can be noticed. It usually happens when you are directed to a website that requires a login.

This practice is very similar to the criminal action that aims to clone credit card data, using a scan of the information contained therein. You need to be very careful not to fall into this type of scam.

SQL Injection via DDoS

DDoS is the acronym for Distributed Denial of Service and is one of the targets of SQL Injection by malicious hackers.

Using a variation of DDoS we know as DoS, Denial of Service, an attack is made by a server or computer that aims to overload the system by taking the target off the internet.

With SQL injection via a rogue DoS using manipulated forms or URLs, it is possible to capture user information, and this tactic often occurs on fake bank pages that aim to steal money or make loans.

There are cases where hackers block access to the information contained in PCs and ask for ransom so that the user can access their own data. This practice has become quite common, being used against government agencies, private companies, and demonstrates the great vulnerability of their systems.

How Does SQL Injection Occur?

SQL Injection occurs when your filters are unable to defend the system and allow many malicious interactions to take place, which ends up creating loopholes for the insertion of some malicious code into the system.

Through codes, the infected system will accept all information inserted in it, being able to give the intruder Adm status, giving them access to each file or data contained in the PC.

The SQL Injection attack via DDoS will overload the server or the computer, which will exhaust memory, processing, and other resources, preventing access. A page with an error or is slow to load can be a sign that the user is under attack.

SQL Injection by DDoS occurs when many sources send requests to the server. Hackers often use home computers that are hacked without their owners knowing, using this so they can access and command their systems.

With this action, the SQL Injection attack comes from multiple locations, which makes it virtually impossible to defend the system. Affected servers become overloaded and unable to handle the volume of requests.

How to Prevent SQL Attacks?

SQL Injection attacks are only possible on vulnerable systems, but it is possible to create defense means with practical actions to increase the security of servers and their users.

Using user-typed data validation is an action to block SQL Injection, as this is one of the main ways hackers obtain information.

Not allowing it to connect to the SQL server through a firewall or by observation helps in defending the system. High-priority websites must be accessed by devices exclusively used by the user themselves.

Always create security logs on your server, so that any attempts at invasive commands can be reported; periodically check the system for any SQL Injection attempts.

The increase in internet bandwidth can also help in a SQL Injection attack, as it can send a volume of data of 80 Gbps per traffic through DDoS, which is a very high rate.

With the increase in the bandwidth rate, it will be possible to resist the attack and create measures to defend user information through servers with greater data reading capacity.

The installation of specialized mitigation devices is a means of defense that comes through installing a firewall, which acts as a SQL Injection prevention and blocking system in your system, being able to block attacks in real-time.

Using local settings, it is possible to increase the bandwidth via traffic through the cloud. One must communicate with the provider to approve this action by creating the automated routing systems in the case of SQL Injection.

With the configuration of your firewall, you will be able to handle large volumes of data connections, showing the importance of increasing bandwidth. Your defense program needs to withstand a large volume of connections, as it will be able to block SQL Injection attacks through these actions.

With this information, a user can start to defend against SQL Injection attacks, but it will not always be possible. In this case, count on the senhasegura team, which will help you in the search for greater protection for your data.

Distributed network visibility, the ultimate weapon against chaos

2022, the world is the technological paradise you always dreamed of. Space mining, smart cities, 3D printers to make your own Darth Vader mask… Just a little problem, society is based on digitization and communications and you have no idea about the visibility of distributed networks. Something of vital importance considering the rise of cybercrime. Well, don’t worry, we’ll help you.

 Do you know everything about distributed network visibility?

Well, the first thing you need to be aware of is the importance of this distributed network visibility. After all, companies around the globe say that the biggest blind spots in their security come from the network, so all their efforts are focused on safeguarding their data by reinforcing this trench. That’s why visibility is key. Even more so if we talk about Managed Service Providers (MSP), the professionals in charge of protecting customer data.

But, what is distributed network visibility? 

To put it simply, distributed network visibility supposes having full knowledge of the different components running within your network to be able to analyze, at will, aspects such as traffic, performance, applications, managed resources and many more, which will depend on the capabilities offered by your monitoring tool. In addition to increasing visibility into your customers’ networks, a comprehensive solution can give you more leverage to strategize based on the metrics you’re monitoring.

For example, MSPs can, with a good visibility solution, help improve the security of their customers by revealing signs of network danger or, through better analytics, make more informed and rigorous decisions about data protection.

As we have warned before, cybercrime is our daily bread in this almost science fiction future that we have earned, and blind spots in network security, along with what will become of the cd, is one of our great concerns.

Monitor traffic, look for performance bottlenecks, provide visibility thanks to a good monitoring tool and alert on irregular performance… That’s what we need. In addition, these super important alerts draw attention and notify technicians and system administrators, who will immediately take the appropriate measures to solve our problem.

If you are an MSP in this post-apocalyptic future that we are living in, it is very likely that you use several applications as part of your services, well, another of the obvious advantages of improved visibility is the ability to participate in application supervision. So, for example, when granular network visibility is set, you may get unquestionable insight into how applications are affecting performance and connectivity. Once you are aware of this, you may choose to filter critical app traffic to the right tools and monitor who is using which app and when. You may even make application performance more practical, reducing processor and bandwidth work by ensuring, for example, that email traffic is not sent to non-email gateways. 

Some challenges to consider

Not everything is having fun and joking around, rolling on the carpet and having crises saved by your expertise, there are several challenges for MSPs associated with network visibility.

Cloud computing has increased and mobile traffic has increased too, this only adds, to our inconvenience capacity, more blind spots to watch out for as MSP. The end has come for the magnanimous and bucolic days of lying on the grass simply monitoring traffic over MPLS links. We are in the future, and WANs are a deadlock for Internet-based VPNs, Cloud services, MPLS, and mobile users. Something complex that many rudimentary monitoring tools cannot offer full visibility of. There are many components to address. To deal with this Gordian knot and its dense complexity, MSPs must be demanding and rigorous when choosing a monitoring tool to work with.

Another of the great challenges that MSPs may face in this field is the fact that the most traditional monitoring methods are closely linked to on-premise devices. This means that all WAN locations need their own set of applications, and these must have their own sources and be properly maintained. Optionally, all traffic can be retrieved and inspected from a WAN location. This inefficient method can have a performance impact.

Due to this inefficiency, it becomes difficult to apply the traditional approach to distributed network visibility. For enterprises with many applications, networking becomes too obtuse and convoluted, with a variety of individual configurations and policies difficult to support. Additionally, there is the capacity restrictions of the devices, which limit the amount of traffic that can be analyzed without the need to update the hardware. This without noticing that at some point the devices will have to be completely patched or replaced. Damn, even if your company grows, which is what we want, network visibility will quickly be constrained and more security vulnerabilities will go unnoticed.

Conclusions and good wishes


I gave you a very bad prospect. But don’t worry, it was only an adverse in crescendo until reaching the great catharsis: While there are many traditional monitoring tools that cannot address distributed network visibility challenges, there are, thank heavens, other monitoring tools that can.  This is the example of Pandora FMS, a monitoring software that is up to the challenges such as those raised and that helps technicians manage complex networks and much more.
