SecOps professionals need to be prepared for key areas in security operations. Interviewers often focus on incident response and threat detection. Below are some common questions:
Incident Response Questions
1. What is the incident response lifecycle?
2. How do you prioritize incidents?
3. Can you describe an incident where you quickly mitigated a threat?
Threat Detection Questions
1. How do you use SIEM tools for threat detection?
2. How do you differentiate between a false positive and a real threat?
Example Python Code for Threat Detection:
import os
log_file = '/var/log/syslog'
with open(log_file, 'r') as file:
for line in file:
if 'error' in line.lower():
print(line)
