The following are some of the main ways to tackle application security threats:

1. Secure coding practices: Implementing secure coding practices, such as input validation, error handling, and encryption, can help to prevent many common application security threats.
2. Regular security testing: Regular security testing, such as penetration testing and code reviews, can help to identify and address vulnerabilities in applications.
3. Threat modeling: Threat modeling is a proactive approach to application security that involves identifying and evaluating potential threats to an application and taking steps to prevent or mitigate these risks.
4. Web application firewalls (WAFs): WAFs are security solutions that protect web applications from a wide range of threats, such as SQL injection, XSS, and CSRF.
5. Use of secure protocols and encryption: Using secure protocols, such as SSL/TLS, and encryption, such as AES, can help to protect sensitive information from being intercepted or accessed by unauthorized users.
6. Access controls: Implementing strong access controls, such as multi-factor authentication, can help to prevent unauthorized access to applications.
7. Regular software updates: Regularly updating software, including the operating system and application software, can help to address known vulnerabilities and prevent exploitation by attackers.
8. User education and awareness: Educating users about security best practices and the potential risks associated with using applications can help to reduce the risk of security incidents.

By taking a multi-layered approach to application security, organizations can significantly reduce the risk of security incidents and protect sensitive data from being compromised.
