Every employee who works in Cyber Security should know how to secure network. His duty contains 2 parts:
Development and Implementation:
Secure coding practices: Writing code that is resistant to vulnerabilities and exploits. This involves following secure coding guidelines and using techniques like input validation and proper data sanitization.
Building security features: Developing security features like authentication systems, authorization controls, encryption modules, and intrusion detection systems.
Integrating security into the development lifecycle: Ensuring that security considerations are factored into all stages of software development, from design to deployment. This might involve threat modeling and security testing.
Staying up-to-date: Keeping current on the latest security threats and vulnerabilities to ensure developed solutions remain effective.
Security Analysis and Maintenance:
Vulnerability assessments: Identifying and analyzing potential weaknesses in existing systems and code.
Penetration testing: Simulating cyberattacks to identify exploitable vulnerabilities.
Security incident response: Participating in the investigation and remediation of security breaches. This might involve analyzing logs, patching vulnerabilities, and restoring compromised data.
Security maintenance: Updating security systems and software to address new threats and vulnerabilities.
