Learning is an essential part of our life. From speaking your very first word, up to using an application, definitely without learning something we can’t survive in this world. This brings us to our topic for this article, which is all about knowing how to secure applications.
You’ll first learn the definition of application security. After that, you’ll see a real-world scenario and examples of application security tools. Finally, we’ll enumerate some guidelines on how to secure applications.
How To Secure Applications: A Definition
When it comes to computing, we often hear people use the word “application” or “app”. But what do they actually meant? An application can be defined as any piece of computer program or software that was designed and created to do a specific job or meet a certain need.
Security in computing, on the other hand, refers to the overall defense structure of your app, system, and network against threats. We can, therefore, say that application security is the process of defending or shielding your application from known and unknown vulnerabilities and threats.
Now that you have a clear understanding of what is application security, in the next section, you’ll see a scenario and examples of how to secure applications.
How To Secure Applications: Scenario And Examples
In this section, you are presented with a real-world scenario. After that, you’ll be given some application security examples. You are doing your daily habit of posting pictures and other stuff on your social media accounts like Facebook, Instagram, and Twitter. Then out of nowhere, someone sent you a private message saying that they’re a fan of yours and they’ve been following your social media adventures since day one.
Because you’re so happy and curious to know them, you replied to their message. This person then asks if you could help them by liking their page as well by clicking the link after their message. You’re still overwhelmed with joy because you’re thinking that you’re just helping a follower or fan. So you clicked on the link and all of a sudden, your computer rebooted by itself and you thought that this was probably a glitch on your ISP’s (Internet Service Provider) side.
Then you noticed a message on your desktop screen that says: “You’re hacked! Everything on your hard drive has been encrypted! If you want your files decrypted, you have to pay us! Contact us by sending an email to firstname.lastname@example.org”
You are now a victim of the latest ransomware attack that has no solution yet. This is a scenario where you were hit by a zero-day malware attack. This wouldn’t happen if you know how to secure applications. This threat could be prevented if you do the following:
- Install an anti-malware program that constantly checks for known and unknown types of viruses, trojans, and rootkits. You can also opt for a cloud-based virus scanner which puts the load on the company’s servers rather than yours.
- Install a firewall and configure it to filter web traffic, based on a set of rules according to your needs.
- Install a program that has a feature called whitelisting.
Those were just some of the examples of how to secure applications. In the next section, you’ll learn the best practices on securing applications.
How To Secure Applications: Best Practices
The following are the most common steps or best practices on how to secure applications:
- 1. Always plan ahead by searching for vulnerabilities in your applications, systems, and networks. You can do this by using a cloud-based vulnerability scanner program.
- 2. After identifying the vulnerabilities, you now deploy the fixes and upgrades using a patch management system. You can do this process either manually or automatically.
- 3. Everything should be fine by now, however, you still need to prevent your applications from being exposed to newer threats like zero-day attacks. You should look for a program that can do this task.
These are the essential steps of best practices on how to secure applications.
How To Secure Applications: Conclusion
You’ve learned the meaning of application security in the first part of this article. You were also presented with a real-world scenario of what could happen to you if you don’t know how to secure applications. You were given some recommendations as well on how to prevent that scenario from happening to you. Finally, you were able to learn and understand the best practices on how to secure applications. You’re now aware of what features you should look for in a product. For more information about this topic, kindly click here.
