Guys, let’s talk about the Network Security Engineer, let us detail the work they ask of him in most companies:
1. Design and implementation of security policies (Security Policy Design & Implementation):
First of all, a network security engineer is responsible for designing and implementing network security policies. This includes limiting network access, managing virtual private networks (VPNs), and configuring firewalls to ensure protection against threats.
2. Network Protection:
It works to secure the network against various attacks such as DDoS attacks, malware, and attacks that target security holes in the network. Sets security devices such as firewalls and intrusion detection systems (IDS/IPS) to detect and prevent any threats.
3. Network Monitoring:
A network security engineer continuously monitors data and network traffic using advanced monitoring tools like Wireshark and SolarWinds. Its goal is to detect abnormal activities or potential threats in real time before they lead to a breach.
4. Security Troubleshooting:
If a breach or security issue occurs in the network, he is the first person to analyze the cause and explore solutions. Check system logs, monitor traffic, and use tools like Ping and Traceroute to identify the source of the problem.
5. Updating and developing security tools (Security Tool Updates & Development):
Oversees the updating of security tools such as firewalls, intrusion detection systems (IDS/IPS), and antivirus software. It is concerned with updating software periodically to increase the effectiveness of the network and protect it against emerging threats.
6. Access Control Management:
Ensures that each user in the network has specific permissions only in proportion to their role. Sets secure access mechanisms such as multi-factor authentication (MFA) to ensure that sensitive information is not leaked or unauthorized access.
7. Security Audits & Penetration Testing:
It periodically tests network security to ensure that there are no security vulnerabilities. Collaborates with security teams in conducting penetration testing to detect and remediate vulnerabilities in the system before attackers exploit them.
8. Documentation:
Everything he does must be well documented. Document changes in the network, add or modify security settings, and any security incident or threat that has occurred. This helps in providing a clear record of reports and also for the development of future actions.
9. Collaboration:
A network security engineer works closely with other IT teams such as system engineers and developers to ensure that integrated systems and infrastructure are fully encrypted and secure.
In short, the role of a network security engineer is very important in protecting the company’s network from threats. With the passage of time and experience, he has great opportunities to develop and increase responsibilities in the field of cybersecurity.
