Firewall Systems
Firewalls are a fundamental component of network security, serving as a barrier between internal and external networks to regulate incoming and outgoing traffic based on predetermined security rules.
Intrusion Detection Systems (IDS)
IDS are security appliances or software applications that monitor network traffic for signs of unauthorized access or malicious activity, alerting security personnel to potential threats in real-time.
Encryption Technologies
Encryption technologies, such as Transport Layer Security (TLS) and Pretty Good Privacy (PGP), are used to secure data in transit and at rest, rendering it unreadable to unauthorized users even if intercepted.
Security Information and Event Management (SIEM) Systems
SIEM systems collect, aggregate, and analyze security data from various sources, including logs, network devices, and applications, to provide comprehensive visibility into an organization’s security posture and facilitate proactive threat detection and response.
Cyber Security Engineer Career Path
Entry-Level Positions
Entry-level cyber security roles, such as security analysts or junior security engineers, typically require foundational knowledge of cybersecurity principles, along with hands-on experience with security tools and technologies.
