As technology advances, various IT terms are also gaining popularity. One of these is cybersecurity. Just like a security guard protecting your home, cybersecurity is needed to protect your devices, systems, networks, and data from various cyber threats.

What exactly is cybersecurity? What are the types and threats you might face related to cybersecurity? How can you strengthen it? Read the full explanation below.!

Cybersecurity is the practice of protecting computer systems, networks, programs, and data from digital attacks aimed at accessing, altering, destroying, or stealing sensitive information. Cyberattacks can occur because malicious actors attempt to gain profit, extort money, or disrupt normal business operations. Cybersecurity involves a combination of technology, processes, and people to build an effective defense against various threats in the digital world.

Understanding Cyber ​​Security

Cybersecurity comes from two English words: "cyber," meaning virtual world (internet), and "security," meaning safety. Terminologically, cybersecurity is a form of protection for systems connected to the internet. This includes hardware, software, and even your data.

Cybersecurity practices are implemented not only by individuals but also by companies and agencies. These measures will help protect data centers and other computer systems from unauthorized access.

A robust cybersecurity strategy can provide robust protection against attacks designed to access, modify, delete, or extort sensitive systems and user data. Cybersecurity also plays a role in preventing attacks aimed at disrupting or even stopping the operation of systems and devices.

Types of Cyber ​​Security

The term cybersecurity is used in a variety of contexts, from business to mobile computing. Based on its type, it can be divided into several general categories:

Network security.

This is the practice of securing a network from intruders, both attackers who intentionally target the system and those seeking opportunities.

Application security.

Application security focuses on keeping software free from threats. Vulnerabilities in software and applications must be addressed during the design and development stages, long before the program is deployed. This is crucial to prevent greater losses later. Information security is needed to protect the integrity and privacy of data, both during storage and in transit.

Operational security.

Operational security encompasses the processes and decisions for handling and protecting data assets. The permissions users have when accessing a network and the procedures that determine how and where data can be stored or shared all fall within the scope of operational security.

Mitigation.

Mitigation processes are crucial for business continuity. They define how a company or organization responds to a cyber incident or other event that results in data loss or disruption to operations. Recovery policies define how a company will restore its operations and all its information to the state it was in before the attack occurred.

Education for end-users.

Data security can also be compromised by the most unpredictable factor: humans, aka users. Anyone can inadvertently introduce a virus into a system by failing to follow good security practices. Therefore, users should also be educated on how to delete or ignore suspicious email attachments, not connect unknown USB drives, change passwords regularly, and other important education that will support security within an organization/company.

Types of Cyber ​​Security Threats

Types of cyber threats include malware (malicious software), phishing (email scams), ransomware (threats that encrypt data and demand ransom), social engineering (psychological manipulation), DDoS attacks (flooding systems with fake traffic), SQL injection (injecting malicious code into databases), and man-in-the-middle (MitM) (communication interception). These threats can come from individual hackers, terrorist groups, nation states, and even disgruntled employees (internal threats).

Malware:

Malicious programs designed to damage, steal data, or take over computer systems, such as viruses, worms, and spyware.

Ransomware:

A type of malware that encrypts the victim's data, then demands a ransom to return it.

Phishing :

A fraudulent tactic that uses fake emails or messages to trick victims into providing personal information, such as passwords or credit card numbers, through a fake website that looks like the real thing.

Social Engineering:

Attacks that exploit human error through psychological manipulation to trick victims into providing sensitive information, accessing systems, or spreading malware.

Denial of Service (DoS) / Distributed Denial of Service (DDoS) attacks:

An attack that floods a network or server with fake traffic, causing the system to become overloaded and inaccessible to legitimate users.

SQL Injection:

A type of attack that injects malicious SQL code into a database to take control and steal sensitive data from the server.

Man-in-the-Middle (MitM):

Attackers eavesdrop on communications between two parties to intercept, modify, or steal data being transmitted.

Advanced Persistent Threat (APT):

A sophisticated and coordinated cyber attack by a group of hackers, often backed by a nation-state, that aims to gain long-term access to a target network.

In conclusion, malicious actions carried out by irresponsible parties to steal data, damage systems, or disrupt business operations can originate from malware, phishing, ransomware, social engineering, and attacks such as DDoS or SQL injection. These threats can originate from external actors, such as hackers or nation-states, or internal actors, such as employees abusing access.
