Cyber-attacks on websites and web apps have been a major threat for some time now, and the Cost of Data Breach Study from IBM Security shows that this is unlikely to change.
The internet is now an integral part of everyday life and the Web is a hotbed of activity, with millions of Web apps being created and used by companies. According to hosting tribunal, there are over 1.9 billion web apps on the internet.
Web apps are especially popular because they provide excellent mobility and accessibility from any device, anywhere, and at any time via a simple Internet connection and this means hackers are targeting them more often.
Web app security needs to be taken seriously if you want to protect your websites from malicious attacks and keep your data safe from hackers.
Too many businesses ignore this crucial point, which has led to some high-profile breaches that have had devastating consequences for those affected.
In this article, we will share some top tips for securing your Web Apps from hackers – starting with the basics!
5 Web Security Tips To Protect Web Apps From Hackers
Never say to yourself, “It won’t happen to me.” The internet has become a space plagued with harmful links, Trojans, and viruses, putting us all at risk and raising the stakes.
Make sure to take the below basic tips seriously to decrease your chance of getting hit!
#1. Perform a frequent data backup
The first tip you need to consider doing is frequently backing up your web app.
OK, we get it. You’re probably thinking “Who does that anymore? It’s a thing of the past”
But believe us, when we say, you will be happy you have your whole website data saved and tucked away in case of a security breach.
Data may be backed up to a central server or even if you have your own local backup it is still safer than not having this practice.
This will allow you to recover your Web App quickly if it is compromised by hackers.
Make sure that any data transfers are encrypted – this means all Web Apps should be using SSL certificates, which encrypt the information transmitted between users and websites.
#2. Keep an eye out for SQL injection
This is one of the most common Web hacking techniques that hackers use to hijack your web applications.
What is SQL injection you ask?
SQL injection is a Web application vulnerability that enables an attacker to access or manipulate data in a Web database by inputting an SQL query into input fields to be processed by an intrinsic SQL database.
Which can result in anything from reading sensitive information like credit card numbers and emails to hijacking account credentials on all kinds of Web sites including Facebook, Twitter, banks, etc.
How to prevent SQL injection attacks?
1. Validate user’s inputs – The validation procedure verifies if the type of input given by the user is permitted. Input validation ensures that the data is of the correct type, length, and format.
Only the values that pass the validation process can be used. It assists in preventing any commands from being injected into the input string. It’s kind of like checking to see who’s knocking before opening the door.
2. Enforce parameterizations – For writing any database queries, you can utilize prepared statements with parameterized queries, also known as variable binding. You can distinguish between user input and code by declaring all SQL code involved with queries, or parameterization.
3. Use whitelists rather than blacklists – Don’t use blacklists to filter user input. An astute attacker will almost always figure out a way around your blacklist. If at all possible, only utilize rigorous whitelists to check and filter user input.
4. Use a web application firewall – A web application firewall is one of the best techniques for detecting SQL injection attacks (WAF). A WAF that sits in front of the web servers watches the traffic that comes in and out and looks for patterns that indicate a threat. It is, in essence, a firewall between the web application and the Internet.
#3. Host your web apps on a dedicated server
Web apps should be hosted on a dedicated server to ensure that your web hosting service can focus all its attention on securing the site. Web app security is often overlooked when shared servers are used for this purpose, which can lead to slower performance and higher chances of attacks by hackers or cybercriminals.
The disadvantages of shared hosting outweigh any benefits it may provide. Because the webserver is shared by several web applications, any assaults will be shared among them as well.
Since your web application is housed on the same server and uses resources from the same resource pool as an organization that has been targeted by attackers who have conducted Denial of Service assaults on its website, your web application will be affected as well.
#4. Arm your web apps against cross-site scripting (XXS)
Cross-site scripting flaws allow an attacker to impersonate a victim user and execute any actions that the user is capable of, as well as access any of the user’s data.
If the victim user has privileged access to the application, the attacker may be able to take complete control of the app’s functionality and data.
#5. Ask white-hat hackers to attack your web app
This is a better approach to detect and become acquainted with your own website security issues, and then fix the vulnerabilities that they discover.
You can successfully guard the access points by understanding the strategies that attackers may use on your web app.
A lot of security experts might say that this is not the right idea. However, there are many benefits to doing so as well.
If you’re going to do it yourself, make sure you don’t break anything by using automated scanning. There may also be complications if your hosting company bans your IP address for attacking your website. Any testing should, of course, be done in a controlled atmosphere.
Web security is one of the most important aspects that businesses need to consider when developing their website.
There are many steps you can take to protect yourself, but your level of protection will depend on how much time and money you want to spend protecting your site.
The more web security measures you put in place, the greater chance there is for hackers to be thwarted in their efforts or not even bother trying at all.
