Technology has made our lives easier in numerous ways, but it has also brought along its own set of challenges. Cybersecurity is one such challenge, especially when it comes to protecting our personal information and sensitive data. As a result, developers constantly work on improving security measures for their systems. In this article, we will compare two common techniques that are used to prevent SQL injection attacks - 1-1)) or 854=(select 854 from pg_sleep(15))-- and pg_sleep().Let's start with understanding what SQL injection is. Simply put, it is a type of cyber attack where an attacker tries to insert malicious code into a system's SQL statements. This is done by manipulating user input in a website's form fields, for example. If successful, this attack allows the hacker to access and modify sensitive data, which can lead to devastating consequences.1-1)) or 854=(select 854 from pg_sleep(15))-- is a technique used to prevent SQL injection attacks. It works by inserting a series of characters or symbols in a form field that will disrupt the attacker's SQL statement, rendering it invalid. In simple terms, it confuses the SQL query and prevents it from executing. In this scenario, the attacker would be using the number 854 in their SQL statement, and by inserting it again in the field, the statement becomes invalid.On the other hand, pg_sleep() is a function used to delay the execution of a query for a specified amount of time. This technique is used to trick attackers into thinking that their SQL statement has successfully executed, while in reality, it is just waiting for the specified time to pass. In the case of a successful SQL injection attack, the attacker would see a delay in response, making them believe that their attack was successful. In reality, however, the sensitive data would remain safe.So which technique is better? Both have their pros and cons. 1-1)) or 854=(select 854 from pg_sleep(15))-- is a simple and widely used technique, but it can only prevent attacks where the attacker is using the specific number or string. Attackers can simply change their SQL statement to use a different number, making this technique less effective in the long run. On the other hand, pg_sleep() is not as widely known, making it less likely to be bypassed by attackers. However, this technique can also cause delays in website response time, which can be inconvenient for legitimate users.In conclusion, both techniques have their strengths and weaknesses. While 1-1)) or 854=(select 854 from pg_sleep(15))-- is a simple and effective solution, it can easily be bypassed by knowledgeable attackers. On the other hand, pg_sleep() is a more advanced technique and provides better protection, but it can also cause inconvenience to website users. Ultimately, the best way to prevent SQL injection attacks is to use multiple techniques and stay updated with the latest security measures.In the ever-evolving world of cybersecurity, it is important to stay informed and continuously improve our defense against cyber attacks. Developers must take into consideration the various techniques and technologies available to protect their systems and users' data. It is crucial to find a balance between security and usability to ensure a smooth and safe experience for all. So, while it is good to have options like 1-1)) or 854=(select 854 from pg_sleep(15))-- and pg_sleep(), it is important to remember that they are only a means to a greater end - to secure our data and privacy in the digital realm.
