The Digital Realm: What Does Cybersecurity Actually Do?

In a world where cyber threats loom around every corner, there are unsung heroes tirelessly working to protect our digital lives. They are the guardian angels of the digital realm, the defenders of our privacy and security – they are cybersecurity professionals. But what exactly does cybersecurity entail? From thwarting hackers and preventing data breaches to safeguarding against online frauds, this blog post delves into their vital role in keeping us safe in an increasingly interconnected world.

What is cyber security?

Cybersecurity is the practice of protecting computer networks and other information systems from unauthorized access, use, or disclosure. Cybersecurity professionals work to protect organizations from a wide range of threats, including those posed by hackers, criminals, and nation-states.

Cybersecurity experts generally classify threats into five categories: network intrusion, data theft, system abuse, denial-of-service attacks, and malware. Network intrusion threats include thieves who gain access to a company’s network in order to steal confidential information or commit fraud. Data theft threats involve hackers who steal data from a company’s computers or servers. System abuse threats involve malicious actors who use systems for their own benefit instead of for the benefit of their organization. For example, a hacker might access a company’s systems in order to delete critical files or damage the company’s reputation. Denial-of-service attacks are attempts to overload a system so that it can no longer serve its intended purpose. Malware is malicious software that infects computers and can cause damage or even death.

The different types of cyber attacks

Cybersecurity is the practice of protecting computer networks and their users from unauthorized access, use, or disclosure. Cyberattacks can originate from a variety of sources, including malicious individuals, cybercriminals, hostile nation-states, and accidental events. It is important to understand the different types of cyberattacks in order to protect yourself and your organization.

A basic cyberattack involves accessing a network or individual’s computer without their permission. This could be done by infiltrating a system through a vulnerability in the software or hardware, or by exploiting an error in user behavior. Advanced attacks involve taking advantage of vulnerabilities previously identified but not yet fixed. Once inside the system, an attacker can seek out sensitive information, disrupt operations, or even destroy data.

To prevent these attacks from occurring in the first place, it is important to have strong cybersecurity measures in place. These measures can include using updated software and hardware; implementing security policies and procedures; training employees on best practices; and monitoring network traffic for signs of suspicious activity. In some cases, law enforcement will also be required to take action against criminal hackers who break into systems with malicious intent.

What do cyber security professionals do?

Cybersecurity professionals work to protect digital systems from attack and exploitation. They may work with systems administrators and other technicians to monitor networks for signs of intrusion, develop and implement preventive measures, or respond to attacks when they occur.

In order to protect against these threats, cybersecurity professionals typically use four main tactics: threat detection and analysis, incident response planning and execution, software security management, and physical security management. Threat detection and analysis involves monitoring activity on company networks in order to identify possible signs of wrongdoing. Incident response planning and execution involves creating policies and procedures for responding to suspected attacks and ensuring that these policies are followed when an attack occurs.

A cybersecurity professional typically has a bachelor’s degree in computer science or related field and several years of experience in the field. In addition, many undergo special training in methods such as vulnerability assessment and penetration testing.


In the age of the internet, cybersecurity is more important than ever. Unfortunately, many people still don’t fully understand what cybersecurity actually does or how it works. This article will provide an overview of what cyber security really is and show you how it can protect your digital life. Armed with this knowledge, hopefully you’ll be able to make smarter decisions when it comes to safeguarding yourself online.
