What Is Cybersecurity?


Cybersecurity is the technology and practice of protecting networks, devices, data and assets from cyberattacks. It includes everything from malware erasing files to hackers accessing bank accounts. It is a constantly evolving threat, and keeping up with attacks can be difficult for many organizations.

With more connected systems than ever, cybersecurity has become increasingly important for businesses and consumers alike. Attacks can be launched by hackers, nation-states or by disgruntled employees. They can be designed to disrupt, steal or damage a system, and they can be carried out on a massive scale. For example, ransomware attacks accounted for a stunning $6 trillion of losses in 2021.

Several key elements comprise cybersecurity, including firewalls, antivirus software, intrusion detection and protection and encryption. Firewalls focus on securing the perimeter of a network, while virus scanners and anti-malware programs work to protect internal systems from malicious code. Intrusion detection and prevention solutions identify potentially hostile activity, while identity and access management (IAM) services limit and monitor employee access to sensitive data. Encryption encrypts data during transmission, preventing attackers from deciphering it.

The most significant security challenges arise with endpoints, which are the laptops, smartphones and other devices that connect to a corporate network. Considering that remote workers frequently use their own personal devices to access company networks, it is crucial to ensure robust endpoint protection. Many fast-growing cybersecurity companies are focusing on this space, with tools that detect and stop threats like ransomware and other malware. SOC
