Whether you are a small business or a business, your web applications are probably one of your most important assets. From marketing and sales to customer service and accounting, there is no doubt that your web applications are integral to the success of your business.
Regardless of the size of your business, it’s essential that you understand how security can protect your business from hackers or compromised data. While not all threats are the same, here are some basic best practices for web application security.
1. Implement a vulnerability management strategy
Vulnerability management is an integral part of any corporate security plan. While it might not be everything, it contributes an important part of a company’s security strategy. Over 50% of cyber attacks happen due to some error or flaw in a system, so keeping your network up to date is essential.
In this case, a vulnerability management strategy focuses on preventing and mitigating risk, which includes a combination of automated and manual processes. Best practices for monitoring web applications address this prevention and mitigation, including:
- Use the right tools to monitor and analyze your assets, making sure your system is not vulnerable
- Leverage automated scans to find vulnerabilities in your systems
- Have a robust incident response plan in the event of a security breach
Since each network has unique vulnerabilities, the most effective solutions combine manual and automated capabilities to analyze and correct potential security vulnerabilities.
You can use Amazon Web Services (AWS) security screening to perform a vulnerability assessment to make sure your applications are secure. This feature is available in S3 and EC2 environments. You can identify your AWS services with the status and an overview of the security plan.
You can also set up an alerts policy, which ensures that appropriate security measures are in place.
2. Logging is essential in the security process
One of the biggest mistakes businesses make is to overlook the importance of logging. Logging is one of the most basic but crucial aspects of any security process. Whether it’s web application code, REST endpoints, or data pipelines, automated analysis can detect and monitor anomalies and resolve any issues early on.
When analyzing web application security, it is important to establish log context by analyzing code rather than data. When examining a complex web application, it can be tempting to dump all logs at the root level, but this is not the right approach.
Instead, you should consider creating regular events to analyze and respond to your app’s activity. It can be beneficial to use security event models and in-depth monitoring to help you optimize the security of your application.
3. Secure your AWS EC2 instance from attackers
Security experts have noticed an increasing trend in attacks on WordPress sites originating from Amazon EC2 instances. Business owners appreciate the convenience of AWS for running and deploying their web applications, but cybercriminals can reap these same technological benefits as well.
By using unsecured AWS instances, a hacker could launch a Distributed Denial of Service (DDoS) attack on your servers by flooding the server with traffic. Since EC2 instances are regularly scheduled, they are susceptible to being recovered by an attacker. In many attacks against WordPress sites, it is assumed that the majority of EC2 instances used come from stolen login credentials.
There are several best practices for securing your EC2 instances, including:
- Following the principles of least access and least privilege.
- Creating a basic server configuration and tracking server configurations as configuration items.
- Have processes to control changes to server configurations.
4. Secure your AWS S3 bucket data from attackers
The cloud is a huge collection of data, so you can’t really avoid becoming a target if you store valuable information on a cloud storage service. Web applications can greatly benefit from using S3 buckets to store static resources, such as images and other types of files. But S3 is also one of the most commonly used cloud storage services, which makes it an extremely important topic for web security.
While using S3 correctly can greatly benefit your website, you should never store critical data in S3 buckets that are not secure. All sensitive data you store in S3 should be protected and encrypted using the most secure standard encryption method available.
5. Securing Your AWS Lambda Function Data From Attackers
Lambda functions are so popular that they were recently added to Amazon Web Services (AWS). These functions are very powerful and can be used in different ways. They allow developers to quickly and easily build new functionality or build web applications that require small, scalable tasks to be performed.
The main purpose of these functions is to execute code within a given time. But as a result, you need to seriously think about how you should make your function safe to operate.
Some methods for securing your Lambda function include:
- Protection against malicious requests.
- Hosting of the function on a secure server or virtual machine.
- Storage of sensitive data in the function itself.
- Make sure that the version of the code used has been fully updated.
- Use of a secure abstraction layer.
So how do you secure a function that is such a crucial component of your cloud applications?
You must provide a set of rules and guidelines that can be applied as a safety measure. This will help you ensure that your Lambda functions protect sensitive data and can have a predictable lifecycle.
