What Is Cyber Security?

Cyber security is a set of measures that protect computer networks, devices, servers and software from malicious attacks, data breaches, identity theft and more. It involves a wide range of techniques and defences including firewalls, anti-virus software, encryption and password management. It also includes educating employees to delete suspicious email attachments, not plug unidentified USB drives into their computers and more.

Cybersecurity is vital for the economy as it helps prevent damage to a company’s reputation, which can be costly and may lead to customer loss. Furthermore, it can help prevent a costly cyberattack which can impact the company’s revenue and operations.

The motivations for attackers vary, but include thrill-seeking hackers, vandals, activists and criminals seeking financial gain. While state-sponsored attack groups are now commonplace, it is often amateur hackers who begin hacking for fun before being recruited by a criminal organisation.

Benefits of Cybersecurity
The key to cybersecurity is to create a system that is designed so any attack is unsuccessful, or results in minimal losses. This requires companies to constantly monitor their systems and be ready to react quickly when a new threat is detected.

To do this, they need a dedicated team of experts to analyse and implement the right tools and techniques. This includes a microkernel approach to operating systems, which runs only the most essential components of the OS in its most privileged level and uses safer and less privileged user space for device drivers, protocol stacks and file systems.MDR
