Web Security Best Practices

On February 4, 2024 / By Olga Yurchak

The virtual arms race is about to move into a new phase. Hackers develop extremely elusive adaptive malware to evade detection software. Cybercriminals never stop trying to exploit web application flaws and obtain unauthorized access to critical information. 

For this reason, it’s critical to comprehend and adhere to essential security procedures.

Essential Web App Security Practices

Let’s discuss nine essential web security practices that every business and organization must implement.

Secure Software Development Life Cycle

A secure software development life cycle (SDLC) is a set of practices and processes that ensure software is designed securely from the planning stage to deployment. It includes procedures such as 

  • Threat Modeling: the process involves a series of steps, including identifying the assets and data that need protection, defining the threat parties, and prioritizing the potential threats. 
  • User Input Validation: the need for user input validation arises because users can enter malicious data that can be used to exploit vulnerabilities in web applications, leading to security breaches.
  • Parameterized Queries: developers can prevent SQL injection attacks and ensure that malicious code cannot exploit application vulnerabilities. Using parameterized queries, they restrict the user’s input to specific data types and lengths, making it challenging for hackers to manipulate the database.
  • Encrypted Databases or Password Managers: improper handling of credentials can make them accessible to unauthorized users. To avoid this, developers must store sensitive information in secure storage facilities such as encrypted databases or password managers.
  • Cryptographic Libraries and Functions: using cryptographic libraries and functions, developers can protect sensitive data from being intercepted or viewed by unauthorized parties. 
  • Regular Code Reviews: automated tools for code reviews help identify security issues and ensure that the application complies with established security standards.

Logging of Security-Related Events

System administrators and security teams should implement logging solutions that monitor and record all activity on the system, including logins, access control changes, and system changes. This information is vital in detecting potential security threats and helps to take appropriate actions in a timely fashion.

Also, ensure that all security-related events are logged and that error messages do not divulge sensitive information. This covers unsuccessful attempts at login as well as other questionable behavior. You can promptly identify and address security incidents by keeping track of security-related occurrences.

Authentication and Authorization Mechanisms

Authentication validates users’ identities and confirms their access rights, while authorization determines what actions users can and cannot perform. Your web application may be subject to brute-force assaults, in which hackers use automated tools to guess usernames and passwords if it has weak authentication procedures, such as easily guessable or reusable passwords.

Companies should use robust authentication methods, like multi-factor authentication (MFA) or two-factor authentication (2FA), to thwart these assaults. In addition to a password, these systems demand users to submit other information, like a code sent to their phone or a biometric factor.

Secure Session Management Techniques

Secure session management involves using secure protocols to manage user sessions. This practice includes techniques such as utilizing safe cookies, limiting session time, and logging out users after a certain period of inactivity. To prevent session hijacking and other attacks, web developers and security teams can implement several session management techniques:

  • Use HTTPS/TLS Protocols: secure communication protocols encrypt session data and prevent attackers from intercepting or modifying it.
  • Implement Session Tokens: unique tokens generated for each session and used to identify and authenticate the user.
  • Implement Cookie Security: cookies should not contain sensitive information and should be properly marked with the secure and HttpOnly flags. 
  • Regularly monitor and terminate inactive sessions: idle sessions are vulnerable to attacks, so completing inactive ones will reduce the risk of hijacking.
  • Use Two-Factor Authentication: this way, you add a layer of security, making it difficult for attackers to access a user’s account.

Incident Response Plan 

An incident response plan is a set of measures and protocols put in place to handle security breaches. This plan includes procedures allowing the team to identify and respond to incidents promptly. It helps minimize the risk of data breaches and improves the organization’s ability to recover from security threats.

An effective IRP should have the following components:

  • A designated incident response team comprises a few people who can quickly assemble to react to an incident. They should have the necessary skills and expertise to investigate, contain, and remediate the situation.
  • An escalation process to ensure that the appropriate individuals are informed of the incident. The plan should define the process and include a list of contact details of key personnel who need to be informed.
  • A defined incident classification system that categorizes incidents into different types based on their severity. This ensures that the response team can prioritize their actions based on the severity of the incident.
  • A defined incident response process should explain how to identify the source of the breach, contain the damage, investigate the incident, remediate the damage, and report the incident to the appropriate parties.
  • Regular testing and updating of the IRP will ensure that it is practical and up-to-date. Updates are necessary as new threats and risks emerge constantly. The response team should receive regular training to ensure they are prepared to manage any possible incidents.

Cultivating Security Awareness

Building a security-aware work culture is a crucial practice for ensuring web security. Employees and staff must be aware of security threats and trained in security best practices. This includes being vigilant about phishing attacks, password management, and keeping up-to-date on the latest cybersecurity threats.

Because the code has the potential to introduce or avoid vulnerabilities, developers are essential to DevSecOps processes (development, security, and operations).But there is more to a robust security culture than just training the development team. Inform every employee of the value of security and their part in keeping it current. Organize frequent security awareness campaigns covering subjects including spotting phishing scams, creating strong passwords, and reporting shady activity.
