According to Trustwave Global Security report, 86% of tested applications have one or more session management vulnerability and 92% of web applications have security flaws and weaknesses which can be exploited as shown in High Tech Bridge Security’s research. That is why businesses are spending heavily on cybersecurity tools that can protect their applications, turning application security into a billion-dollar industry.
With most companies moving to the cloud, the focus is slowly but surely shifting from securing hardware such as the best dedicated server, databases, networks to software and apps. Businesses are opting for secure application development methods to ensure there are no loopholes in their applications which hackers can exploit.
In this article, you will learn about seven application security best practices that every business should follow to keep their applications safe.
1. Secure the Container
Your application uses many microservices and containers to support those microservices. That is why it is important to secure the application container. Keep a close eye on services that are exposed to the network, which could make them vulnerable to cybersecurity attacks. Unfortunately, it is quite challenging to keep track of all the services running inside a container so keeping an eye on suspicious activities is out of question.
Fortunately, these containers have a shorter lifespan than the applications, offering little room for hackers to do the damage. Hackers have found a way to overcome this hurdle as well by creating shadow containers which allow their rootkits to stay effective even after the container is rebooted. The easiest way to prevent attacks on container is to limit access and reduce privileges.
2. Make Security a Shared Responsibility
Start by making web application security a shared responsibility. Whether you are a developer, administrator or a member of operation team, everyone should play their role to ensure foolproof application security. If image scanning is an integral part of continuous integration cycle, you can easily identify new vulnerability but what if it is not? By conducting regular image scanning, you will be alerted as soon as a new vulnerability is found in the code. You don’t have to scan the containers either because scanning the images is like scanning the container.
3. Create A Vulnerability Assessment Process
Patching a vulnerability in a container is different from a traditional setup. Containers contain two different components called base and application image. This means that you must first update the base image then make changes to the application image. With an effective vulnerability assessment process in place, identifying loopholes in containers and application will not be difficult.
Most vulnerability scanners offer container scanning facility which highlights vulnerabilities and configuration issues. By default, these tools check software packages to find errors, but you can still configure these tools to check against vulnerability databases such as National Vulnerability Database (NVD) and Common Vulnerabilities and Exposures (CVE).
4. Embrace Isolation
What makes containers stand out is their ability to isolate applications, processes, data and users. This allows you to offer them the lowest privilege needed for effective operations. If your container is running on the host, vulnerability on host’s side can provide an opening to hackers to enter your container. Similarly, if the hacker successfully breaks out of the container and reach the host, it can gain root-level access on the host. Where possible, run containers with fewer privileges and never run containers as a root user.
5. Centralized Access Control
By implementing centralized access controls, you can define and enforce access control for active containers. Giving too much access to a developer can be risky from both security and audit perspective. It can be a challenge to figure out what took place when. More importantly, if cyber criminals somehow manage to gain root access, they will be in charge of all the containers and can do far more damage than they could do otherwise.
6. Real-Time Threat Detection
Irrespective of how strong your vulnerability scanning and container security is, bugs and errors can still slip through at runtime. These bugs and errors can be exploited by hackers. They can use it as a ladder to get access to your systems. That is why it is imperative that you have a real-time threat detection system in place. Having a threat detection system is not enough especially if it is not backed up by equally good incident response strategy.
