Whilst a UPS battery shop can provide you with all the power you need, and your server rooms can grow and expand to fit your business, you can never be so confident about being safe in the online space.
Given how many current applications are data-driven and easily accessed online, SQL injection vulnerabilities are now very commonly exploited with ease by the criminal element.
In just the first three months of 2019, the UKFast Threat Monitoring service recorded almost 30,000 different SQL injections attempts on client servers. When you look at it in terms of the global scale, this kind of cyber-attack is one that impacts millions of different organisations on a daily basis. //All data-driven applications that utilise an SQL database happen to be possible targets. As such, what steps can you take to protect yourself? //What exactly are SQL injection attacks?
Hackers come up with a deliberately malicious SQL statement to put into the input fields of an SQL database where they get executed. When this happens, the application will actually perform whatever action is written in that malicious coding.
This kind of attack happens because of vulnerable online applications that are improperly coded. Such flaws happen because the entry fields which are left available for inputs from users suddenly let SQL statements slip through for direct database query.
Personally identifiable information is also known as PII, and stealing this data is often the reason for such an attack. These SQL injection attacks have a number of potentially negative consequences. They include but are not limited to the following:
-Extraction of PII or other sensitive information, which can cause a data breach that might incur significant finds and/or reputation damage via the GDPR
-Listing out authentication information like passwords and log-ins, which might be utilised in future attacks
-Database corruption or deletion that renders a website nonfunctional
-Attacks on other network systems via the compromised database
Given that so much is at stake, is there anything you can do to prevent SQL injection attacks from crippling your applications and website? Yes, so keep reading to learn what a few of them are:
1) Parameterised Statements
Parameterised statements by nature are dynamic. This permits faster executions, and they are the top method for preventing SQL injection attacks.
Use parameterised database queries alongside typed and bound parameters. Also, be careful about the use of any parameterised procedures that are stored within the database.
This makes sure that any statements that get input into your organisation’s SQL database stay safe. The parameters and string will get passed separately to the database, which lets the database driver interpret them correctly, meaning your code won’t be susceptible to an attack.
2) Use a WAF
Any WAF will have thousands of different rulesets covering a number of frequent application-layer attacks, and SQL injection is one of them. When using WAF as a primary layer of defence, your online apps are going to enjoy effective protection from attempts at SQL injection, even when your code might still have a few weak links.
3) Scan Everything For Potential Vulnerabilities
Hackers are always trying to probe websites online for coding flaws. Tools which automate and exploit the discovery of any SQL injection flaws mean a faster return on their investment for cybercriminals, since their odds of success are greater.
Specialised vulnerability scans that focus on SQL injections can help you find SQL injection flaws and any online vulnerabilities that relate tot hem.
4) Object Relational Mapping Frameworks
An ORM framework can get written in several different programming languages. It’s also designed to be a virtual wrap or covering over your SQL database.
This framework alone isn’t going to give you immunity from SQL injections, but it will let you construct SQL queries in languages that you are personally familiar and fluent with. This simplifies the process, leaving far less room for exploitable code errors. It has a range of prebuilt features that you can use to bolster your security. Parameterised statements are standard, and you can use SQLAlchemy which is a python toolkit.
5) The Principle of Least Privilege
If your database winds up getting compromised, if you employ the principle of least privilege, it at least keeps an attacker from having access to any other parts of your network. Use this principle when you provision any accounts that are going to connect with the SQL database.
6) Password Hashing
If you do happen to have an SQL injection attack, then password hashing is going to be essential to minimising any damage, since every password is going to be rendered unreadable.
If your organisation stores unencrypted passwords at all, then that is a huge security flaw by itself. Applications need to store user passwords like robust and one-way hashes, ideally salted. This will minimise the risk of any malicious users coming and impersonating users or stealing their credentials.
