Familiarity with firewalls, intrusion detection/prevention systems (IDS/IPS), vulnerability scanners, and certifications such as CISSP or CompTIA Security+ is highly valued. Strong analytical thinking, problem-solving abilities, and effective communication skills help professionals excel in cross-functional teams. These skills are vital for safeguarding critical systems, ensuring compliance, and effectively responding to security incidents in a constantly evolving threat landscape.
