What Is Cybersecurity?
Cybersecurity is the field of technology that helps protect businesses and individuals from cyberattacks. With sensitive data being transmitted and stored online, cyber threats pose serious risks to personal privacy, financial stability and national security. Frequent high-profile data breaches emphasize the need for robust cybersecurity measures to help mitigate these risks.
Cyberattacks include malware erasing files, hackers using social engineering tactics to steal sensitive information and identity, and Advanced Persistent Threats (APTs), which are prolonged attacks by well-funded adversaries. These malicious activities often go unnoticed and can have a huge impact on an organization’s operations.
Malware includes viruses, worms and Trojans that infect computers, networks and servers with the intention of compromising data or damaging systems. Phishing attacks phish victims into revealing confidential information by impersonating trusted entities and Advanced Persistent Threats attack networks in an attempt to exploit and manipulate them for long periods of time.
Endpoint security provides protection to the devices that access an organization’s network, including laptops, desktops, smartphones and tablets. Zero trust is a modern security model that assumes nothing inside a network is trusted by default, instead requiring constant verification of access to critical data and resources through rigorous authentication protocols.
Security professionals use a variety of tools to detect and respond to cyberattacks, such as intrusion detection, firewalls and network security appliances. They also rely on regular security audits and penetration tests to identify and address vulnerabilities before cybercriminals take advantage of them. They must also stay up-to-date with emerging threats by deploying granular, automated monitoring solutions and developing employee awareness through training programs to spot increasingly sophisticated phishing attempts.
