Cyber security is the set of technologies, measures and practices that protect computers, networks, data, applications, financial assets and other critical infrastructure from cyberattacks. These threats can come from unauthorized or malicious users, like hackers or rogue state actors, who seek to steal data, disable systems or use other tactics for illicit gains.
One of the most important reasons to study cybersecurity is that a data breach can cost a company dearly. Not only does it erode customer trust and cause damage to reputation, but it also takes a lot of time and money to get back on track after losing essential information. An effective cybersecurity system will prevent these risks, and it can help a business to thrive in the long run.
Attackers can gain access to a system in a variety of ways, including direct attacks (hacking or physical breach), ransomware, malware, phishing and other spyware. They may also deploy denial-of-service attacks, which flood the target with traffic or requests, and man-in-the-middle attacks, which intercepts communications between two parties. Attackers can also compromise security through operating system modifications, software worms and covert listening devices.
The field of cybersecurity is constantly evolving as attackers find new ways to gain access to sensitive data and cripple or destroy systems. It’s important for cybersecurity professionals to remain curious and up-to-date on the latest threats and best practices. The US government has developed a cybersecurity framework that can help organizations to mitigate the risk of an attack and recover from successful attacks. SOC
