Application Security Best Practices To Prevent Threats

In today's digital world, application security is essential for businesses to protect their data and services from malicious actors. Whether you're developing a mobile app or web service, the right set of practices must be implemented in order to safeguard your applications from any potential threats. In this blog post, we will discuss some of the most popular application security best practices that should be applied when developing applications or services in order to ensure their protection against cyber-attacks. So let's get started.

Why is Application Security Essential?

Recently, the popular online retail company Amazon faced a security breach. The incident was identified by the company's internal teams and reported to customers through an email alert. According to their investigation, hackers had gained access to customer accounts using stolen credentials obtained through a third-party application that stored user names and passwords in plain text without any encryption or hashing.

As soon as they discovered the intrusion, Amazon took swift action by implementing additional layers of authentication for all accounts associated with this vulnerable app and restricted access to sensitive data such as credit card numbers. In addition, they notified affected customers about the incident and recommended they take measures like changing their passwords regularly and enabling two-factor authentication on devices connected to their accounts. This story serves as an example of why it is important for businesses to prioritize application security best practices so that hostile actors cannot exploit vulnerabilities in order to gain access to sensitive information.

Application Security Best Practices

In order to protect applications and services from cyber threats, there are several security best practices that businesses should prioritize. Here is a brief overview of top 9 application security best practices:

#1: Secure Coding and Software Development Lifecycle (SDLC)

Secure coding practices ensure that developers write code with security in mind by preventing vulnerabilities such as buffer overflows, SQL injection, and cross-site scripting. Secure coding also includes avoiding insecure configurations, hardening the application's environment, and using secure development frameworks. The SDLC ensures that the application is tested at each stage of the development process, from planning and requirements gathering to testing and deployment. Here are some tips to incorporate secure coding practices:

• Ensure that code is written in an organized and readable manner as this will make it easier to spot and fix any security flaws.
• During development, use tools and techniques like static code analysis to identify and remove security vulnerabilities.
• Keep code up-to-date with the latest security patches and updates.

#2: Authentication and Authorization

Authentication is the process of verifying a user's identity and is usually done through passwords, tokens, or biometrics. It helps to ensure that only authorized users can access the application or service. Authorization is the process of granting privileges to users, such as access rights and permissions. Both processes are essential for protecting applications from threats. Below are some ways to implement authentication and authorization:

• Implement strong authentication measures such as two-factor authentication, secure passwords, and biometric authentication.
• Use access control mechanisms to ensure that only authorized users are able to access specific areas of the application or service.

#3: Threat Analysis through Monitoring and Logging

Threat Analysis through Monitoring and Logging is an essential part of any cybersecurity strategy. Monitoring helps organizations detect malicious activities, while logging provides a record of user activity, such as logins, file accesses, or other changes. These activities can be monitored in real-time or retrospectively, allowing an organization to have visibility over the security of its applications. By following the tips given below you can do a threat analysis:

• Ensure that all activity-related logs are stored and monitored in a secure location.
• Set up an alert system to notify the security team of suspicious activities.
• Regularly review logs and monitor application performance for any potential threats or vulnerabilities.

#4: Enforcing Encryption Standards

Encryption is a process of coding data so that unauthorized users cannot access it, and is essential for protecting sensitive information from malicious actors. It works by converting plain text into a scrambled format, which can only be decrypted with the right key. It is important to enforce strong encryption standards to ensure the safety of applications and services. There are some ways to enforce encryption standards, such as:

• Ensure that all confidential data is encrypted using strong algorithms such as AES, RSA, SHA256, and others.
• Use Transport Layer Security (TLS) to encrypt communication between applications and services.
• Use secure protocols like HTTPS for all web-based communications.

#5: Developing a Secure Architecture

A secure architecture is designed to ensure the confidentiality, integrity, and availability of the system. It involves taking a holistic approach towards security, involving measures such as isolating resources from unauthorized users, implementing access control systems, and creating backup systems in case of system failure. You can develop a secure architecture using the following tips:

• Use a framework such as the Secure Software Development Life Cycle (SDLC) to ensure that secure coding practices are followed when developing applications.
• Separate resources within the application using logical and physical barriers.
• Set up firewalls and other security measures to protect against malicious attacks.

#6: Implementing Access Controls to Restrict User Activity

Access controls are used to restrict user activity and ensure that only authorized users can access the application or service. This process involves granting different levels of access rights and permissions, such as read, write, execute, and delete, to users based on their role. Access control systems should also be regularly monitored and audited to ensure that they are functioning correctly. Here are some best ways to implement access controls:

• Establish roles and responsibilities for users, assigning access rights and permissions based on their role.
• Implement a mechanism to audit and monitor user activity on the system.
• Set up alerts to notify administrators of any suspicious activities.

#7: Testing for Vulnerabilities Regularly

Vulnerability testing involves scanning applications and services for potential weaknesses that can be exploited by attackers. It helps organizations identify any flaws within the system before they can be used to gain unauthorized access. It also helps them detect any changes in the system that may indicate malicious activities. Regular vulnerability testing should be done to ensure the security of applications and services. The following ways will help you test vulnerabilities regularly.

• Perform regular checks for known vulnerabilities and patch any found issues as soon as possible.
• Perform periodic vulnerability scans with automated tools to identify any potential threat areas.
• Respond quickly to any security incidents and take appropriate measures to mitigate the risk.

#8: Updating Systems with the Latest Patches and Security Updates

Updating systems with the latest patches and security updates is one of the most important security best practices that businesses should prioritize when developing applications or services. The frequency of patching and updating will depend on an organization's risk level, but it should be done regularly to ensure the safety of their systems. Patching helps organizations address known vulnerabilities and mitigate other security risks, while updating helps ensure that the system remains compatible with new technologies. Below are some points to keep in mind while updating systems:

• Develop a patching and updating plan for the system according to its risk level. The more critical the system, the more often it should be patched.
• Test patches and updates before deploying them to the system.
• Monitor and log changes made to the system for detecting any malicious activities.

#9: Establishing Incident Response Protocols in Case of an Attack

Incident response protocols provide organizations with a framework and plan of action that should be followed in case of a security breach or attack on the system. An effective response protocol should include steps such as identifying the cause of the attack, collecting evidence, mitigating the damage, and restoring system services. This process should be regularly reviewed to ensure that it is up-to-date with the latest security measures and threats. By following the simple steps outlined below, you can establish incident response protocols.

• Establish a designated security team or personnel to handle any incidents that may arise. This team should be well-versed in dealing with security breaches.
• Develop an incident response plan that outlines the steps to be taken in case of a security breach.
• Provide regular training to personnel on handling incidents in a secure manner.
