12/07/2023by admin0Read: 6 minutes

In today’s digital age, securing your business applications is critical to ensure data privacy, protect sensitive company information, and eliminate potential threats that can compromise your operations and computer security. Hence businesses in Australia should prioritise application security to safeguard their valuable assets and combat cyber threats.

In this blog post, we will discuss common application security risks and highlight important steps businesses can take to mitigate them, ensuring a secure and smooth-operating environment.

Application Security

Application security refers to the practice of protecting software applications from potential threats and vulnerabilities that could compromise their confidentiality, integrity, or availability.

It involves designing, implementing, and maintaining security measures and controls throughout the application development lifecycle to minimize the risks associated with unauthorised access, data breaches, denial-of-service attacks, and other security incidents.

The goal of application security is to ensure that software applications are resistant to attacks and can withstand various types of malicious activities. This includes protecting against common vulnerabilities such as injection attacks, cross-site scripting (XSS), cross-site request forgery (CSRF), and insecure direct object references (IDOR), among others.

Organisations should implement secure software development practices to ensure security at every stage of the software, which will further help in application security.

Importance of Application Security for Business Success

Application security is not just a technical requirement but a critical aspect of overall business strategy. As businesses collect and store vast amounts of sensitive customer data, any breach or compromise can lead to severe consequences, including reputational damage, financial loss, and legal liabilities.

By implementing robust application security measures, businesses can safeguard their intellectual property, and customer data, and maintain the trust and confidence of their stakeholders.

In addition, secure applications enable businesses to comply with privacy regulations and industry standards, avoiding regulatory penalties and ensuring business continuity.

a) Application Security as a Service (SECaaS)

Traditional approaches to application security can be resource-intensive and time-consuming for businesses, especially those lacking in-house expertise. This is where Application Security as a Service (SECaaS) comes into play.

SECaaS offers businesses the flexibility to outsource their application security needs to specialized providers who have the knowledge and tools to protect applications from various threats.

By leveraging SECaaS, businesses can tap into the collective expertise of security professionals, benefit from continuous monitoring, and receive timely updates on emerging vulnerabilities and attack vectors. This allows businesses to focus on their core competencies while maintaining a high level of application security.

b) Private Security Measures for Business Applications

In addition to SECaaS, businesses should implement various private security measures to bolster application security within their environments.

Strong access controls and user authentication mechanisms should be in place to ensure that only authorized personnel can access critical applications. Regular security testing and vulnerability assessments help identify weaknesses and prioritize remediation efforts. Applying threat modelling and risk assessment methodologies allow businesses to proactively identify and mitigate potential threats.

Moreover, integrating security practices into the software development lifecycle helps ensure that security is built into applications from the ground up. This includes secure coding practices, code reviews, and security testing at all stages of development.

Application Security Risks and Mitigation Strategies

The key application security risks have been briefly explained below with mitigation strategies provided for each:

1. Injection Attacks:

Injection attacks result from mishandling untrusted data. The most popular injection attacks are SQL injections, where malicious SQL code exploits vulnerabilities within the database layer of an application. These attacks can lead to unauthorised access to sensitive information or, in some cases, a complete takeover of company systems.

Mitigation Strategies:
  • Validate all user input and enforce strict data validation rules.
  • Use prepared statements with parameterized queries or use stored procedures in your database when applicable.
  • Regularly update your application’s database software and ensure it is running on a secure platform.

2. Broken Authentication:

Broken authentication occurs when attackers exploit vulnerabilities in the authentication process itself, gaining access to user accounts. This may involve weak passwords or insecure session management practices that give an attacker access to private user information.

Mitigation Strategies:
  • Implement multi-factor authentication (MFA) that requires users to use multiple methods to verify their identity.
  • Properly hash and salt-stored passwords.
  • Utilise secure session management techniques, such as using cookies with the ‘Secure’ and ‘HttpOnly’ flags.

3. Cross-Site Scripting (XSS):

XSS attacks target applications that fail to handle unsafe user input correctly. They involve injecting malicious JavaScript code into webpages viewed by other users, leading to unauthorised data access and security breaches.

Mitigation Strategies:
  • Employ output encoding while rendering webpages with untrusted data.
  • Implement strong input validation to prevent unsafe data submissions.
  • Use a Content Security Policy (CSP) to prevent unauthorised content execution in the browser.

4. Insecure Deserialisation:

Insecure deserialisation is a significant risk from attackers reusing objects and manipulating serialised data, leading to remote code execution, denial-of-service (DoS) attacks, and unauthorised access to sensitive information.

Mitigation Strategies:
  • Use secure libraries that minimize object creation and manipulation vulnerabilities.
  • Implement sandboxing with limited permissions for deserialised data.
  • Encrypt serialized objects to deter tampering with the serial stream.

5. Misconfiguration:

Application misconfigurations expose businesses to a multitude of risks, from unauthorised access to sensitive data exposure. Attackers can easily exploit loopholes in poorly configured applications, making it important to regularly review security configurations and follow stringent best practices.

Mitigation Strategies:
  • Stick to established secure configuration guidelines and frameworks.
  • Regularly perform security assessments and system audits to identify potential vulnerabilities.
  • Implement tools that automate the monitoring and management of your security configurations.

Threat Modelling and Risk Assessment

Threat modelling and risk assessment play a crucial role in ensuring robust application security. By identifying potential threats and evaluating their severity and impact, organizations can effectively prioritise their security measures and develop risk mitigation strategies.

Threat Modelling for Application Security

Threat modelling is an essential process in the application security lifecycle. It involves identifying potential threats and analysing their impact on the application. By understanding these threats, organizations can take proactive measures to address vulnerabilities and prevent security breaches.

  • Identifying and Analysing Threats

During the threat modelling process, various threat sources, such as hackers, malicious insiders, and unauthorized users, are identified. By analysing these threats, organizations can determine their potential impact on the application’s security.

  • Prioritising Threats based on Severity and Impact

Threats are then prioritised based on their severity and potential impact. This allows organisations to dedicate their resources towards addressing the most critical threats first. By mitigating high-risk threats, organisations can significantly enhance their overall application security.

Risk Assessment Techniques for Application Security

In addition to threat modelling, risk assessment techniques help organisations evaluate and quantify the potential risks associated with application security. By understanding the likelihood and impact of these risks, businesses can effectively implement risk mitigation strategies.

  • Quantitative and Qualitative Risk Assessment Methods

Quantitative risk assessment involves assigning numerical values to risks based on factors such as probability, impact, and vulnerability. This method allows organizations to measure and compare risks objectively. Qualitative risk assessment, on the other hand, relies on expert judgment and subjective analysis to evaluate risks.

  • Risk Mitigation Strategies

Risk mitigation strategies are essential for reducing the potential impact of identified risks. This can include implementing robust access controls, regularly updating software, and carrying out comprehensive security testing. By adopting these strategies, organizations can proactively reduce their exposure to security threats and vulnerabilities.

Defence Mechanism in Application Security

Application Security involves a multilayer of defence mechanisms to shield applications from cyber threats.

We have described them below:

1. Secure Coding Practices:

Developers follow coding standards and best practices to reduce coding errors and vulnerabilities that can be exploited.
