Introduction

Nowadays there are more devices than people, and attackers are becoming more innovative and smart to attack on someone’s personal data or personal device or in a big system. And here we need cyber security and cyber security awareness to protect our data. 

Cyber security also called Information Technology (IT) security. Cyber security refers is the process to protect systems, networks, programs, and data from digital attacks, damage, or unauthorized access. 

Why Cyber Security is Important?

We save or personal, professional, or private information, images, and documents in our devices, network, or in a system. As well as government, military, corporate, medical organizations store uncommon amounts of data on systems, networks, or devices. 

These uncommon data can be hacked or attacked and misused for negative purposes. So cybersecurity works with the multiple layers of protection spread across the computers, networks, programs or data to keep it safe. 

Malware

A malware is a software, program, or file that causes damage to a computer. Computer viruses, worms, Trojan horses and spyware are the types of malware. A malware authors use a variety of physical and virtual ways to spread malware such as USB drive or the internet through drive-by download that damages devices and networks. 

It can perform a variety of different functions such as stealing, deleting sensitive data, modifying or hijacking core computing functions, and computer activity without their permission. 

Phishing

Phishing is a type of social engineering attack and the most common type of cyber-attack. It often used to steal user data, including login credentials and credit card numbers by sending fraudulent emails that duplicate emails from reputable sources, instant messages, or text messages. 

Such texting ways contain links and the recipient is then tricked into clicking those malicious links which can lead to the installation of malware.

Ransomware

A ransomware is a type of malware that encrypts a user’s files. A ransomware is designed to force extract money by blocking access to files or the computer system until the ransom is paid. After paying the ransom does not assure that the files will be recovered or the system restored.

Attackers choose several different ways to attack organizations they target with ransomware. Mostly they target those who are with less security and easy to attack. 

Social Engineering

Social engineering is a broad range of malicious activities accomplished through human interactions. This form of attack uses psychological manipulation to trick users into making security mistakes or giving away sensitive data. Social engineering targets people by performing phishing, pretexting, baiting, and tailgating. 

A social engineering attack in steps, first investigate the target person to collect necessary background information like potential points of entry and weak security protocols. Then they start gaining the victim’s trust and break security practices, such as revealing sensitive data or collecting access to critical resources.

Most of the cyber threats can be mitigated through awareness and best practices in cyber security.
