I have extensive experience with various network security protocols including TCP/IP, SSL/TLS, and IPSec. In my previous role, I implemented a VPN solution using IPSec to secure remote access, which reduced unauthorized access incidents by 30%. I also regularly monitor and update firewall rules to ensure the integrity and confidentiality of our network traffic.

I stay updated by regularly reading industry publications, attending webinars, and participating in security forums. I also subscribe to several security mailing lists and follow leading security researchers on social media. This proactive approach helps me identify emerging threats and vulnerabilities, allowing me to implement timely countermeasures.

In my last job, I detected a breach where unauthorized access was attempted through a phishing attack. I quickly isolated the affected system, changed compromised credentials, and conducted a thorough investigation to identify the entry point. I then updated our security policies and conducted training sessions to prevent future incidents.

I utilize a variety of tools including SIEM solutions like Splunk and ELK Stack for real-time log analysis. For threat detection, I use tools like Wireshark for network analysis and Metasploit for penetration testing. These tools help me identify anomalies and potential threats efficiently, ensuring a robust security posture.

I prioritize tasks based on the risk level and impact of potential threats. Critical vulnerabilities and active threats are addressed immediately. I also use project management tools to track ongoing tasks and ensure timely completion. Regular risk assessments help me adjust priorities as needed, ensuring a balanced approach to security management.
