Linode blog: Guides to improving app security

I have written a series of blog posts to help developers improve their security posture.

Thanks to Covid challenges, there is a more complicated business environment and a higher collection of risks. Supply chains are more stressed, component transportation is more complex, and new software is needed to manage these changes. Businesses have more complex compliance requirements, which also ups the risk ante, especially if they run afoul of regulations or experience a data breach. Attackers are more clever at penetrating corporate networks with stealthier methods that often go without any detection for weeks or months.

Cybersecurity continues to be a challenge as adversaries come up with new and innovative ways to penetrate computer networks and steal data. One of the more popular attack methods is ransomware. There are tools to defend yourself against potential attack and techniques to strengthen your computer security posture. In this post, I describe how these attacks happen, what you can do to defend yourself and how to prevent future attacks.

The days where software developers wrote their application code in isolation of any security implications are over. Applications are exploited every minute of the day, thanks to the internet that connects them to any hacker around the planet. Application security doesn’t have to be overwhelming: there are dozens if not hundreds of tools to help you improve your security posture, prevent exploits, and reduce configuration errors that let bad actors gain unauthorized access to your network. In this post, I review the different kinds of appsec tools and best practices to improve your security posture.

Security starts with having a well-protected network. This means keeping intruders out, and continuously scanning for potential breaches and flagging attempted compromises. Sadly, there is no single product that will protect everything, but the good news is that over the years a number of specialized tools have been developed to help you protect your enterprise network. Your burden is to ensure that there are no gaps in between these various tools, and that you have covered all the important bases to keep your network secure and protect yourself against potential harm from cyber criminals. New security threats happen daily as attackers target your business, make use of inexpensive services designed to uncover weaknesses across your network or in the many online services that you use to run your business. In this post, I review the different types of tools, point out the typical vendors who supply them and why they are useful to protect your network.

As developers release their code more quickly, security threats have become more complex, more difficult to find, and more potent in their potential damage to your networks, your data, and your corporate reputation. Balancing these two megatrends isn’t easy. While developers are making an effort to improve the security of their code earlier in the software life cycle, what one blogger on Twilio has called “shifting left,” there is still plenty of room for improvement. In this guide, I describe what are some of the motivations needed to better protect your code.

Many developers are moving “left” towards the earliest possible moment in the application development life cycle to ensure the most secure code. This guide discusses ways to approach coding your app more critically. It also outlines some of the more common security weaknesses and coding errors that could lead to subsequent problems. In this post, I look at how SQL injection and cross-site scripting attacks happens and what you can do to prevent each of them.

Application security testing products come in two basic groups and you need more than one. The umbrella groups: testing and shielding. The former run various automated and manual tests on your code to identify security weaknesses. The application shielding products are used to harden your apps to make attacks more difficult to implement. These products go beyond the testing process and are used to be more proactive in your protection and flag bad spots as you write the code within your development environment. This guide delves into the differences between the tools and reviews and recommends a series of application security testing products.
