What Is Cybersecurity?
Cybersecurity is the set of tools and practices that protect systems, networks, applications, data, and devices from digital attacks or unauthorized access. It is a complex and ever-evolving field that requires teams of people and technology working together to ensure success.
Cyberattacks can steal confidential information, compromise customer relationships, and even threaten the existence of an entire company. For example, personal information for 147 million people was compromised in the 2017 breach of credit reporting agency Equifax. Strong cybersecurity not only protects a business from financial ruin, but it also safeguards its reputation and shows customers that the company takes their privacy seriously.
Computer security is comprised of three major areas: detection, prevention, and response. The first step is identifying vulnerabilities in systems and networks. This is accomplished through monitoring, scanning, and penetration testing. Vulnerabilities are then prioritized based on the potential impact to operations and data. The next step is to implement cybersecurity solutions that address identified gaps. This includes implementing policies and procedures that define roles, responsibilities, and communication channels during a crisis. It is also important to regularly test incident response plans to maintain readiness.
There is a high demand for cybersecurity professionals. A cybersecurity degree can open doors to a variety of career opportunities including positions in IT, risk management, and business administration. Those interested in pursuing a career in cybersecurity should start by exploring their existing technical knowledge, interests, and career goals. Then, explore opportunities to build on those skills by attending a cybersecurity conference, joining a local cybersecurity meetup group, or taking a beginner-friendly course in coding or networking.
