2.2 Application Security

Secure Software Development:

• Understand the principles of secure coding to prevent common vulnerabilities like buffer overflows, SQL injection, and cross-site scripting (XSS).

Web Application Security:

• Master the OWASP Top 10 vulnerabilities and how to mitigate them.
• Study tools like Burp Suite, OWASP ZAP, and Acunetix for performing web application penetration testing.

Code Review and Audits:

• Learn how to perform secure code reviews and conduct static and dynamic analysis of web applications and software to uncover vulnerabilities.

2.3 Endpoint Security

Malware Analysis:

• Understand the different types of malware (viruses, worms, trojans, ransomware) and how they infect systems.
• Learn how to use tools like Sandboxing, Static and Dynamic Analysis tools, and Reverse Engineering techniques to analyze malware.

Antivirus and Endpoint Protection:

• Study the role of antivirus software and endpoint protection platforms (EPP) in preventing, detecting, and responding to cyber threats.

Endpoint Detection and Response (EDR):

• Learn how to use EDR solutions to detect, investigate, and respond to advanced threats on endpoints.
