OWASP Top 10 - Answer-The Open Web Application Security Project (OWASP) is a
non-profit organization dedicated to providing unbiased, practical information about
application security.
1. Injection
Injection flaws, such as SQL injection, LDAP injection, and CRLF injection, occur when
an attacker sends untrusted data to an interpreter that is executed as a command
without proper authorization.
* Application security testing can easily detect injection flaws. Developers should use
parameterized queries when coding to prevent injection flaws.
2. Broken Authentication and Session Management
Incorrectly configured user and session authentication could allow attackers to
compromise passwords, keys, or session tokens, or take control of users' accounts to
assume their identities.
* Multi-factor authentication, such as FIDO or dedicated apps, reduces the risk of
compromised accounts.
3. Sensitive Data Exposure
Applications and APIs that don't properly protect sensitive data such as financial data,
usernames and passwords, or health information, could enable attackers to access
such information to commit fraud or steal identities.
* Encryption of data at rest and in transit can help you comply with data protection
regulations.
4. XML External Entity
