What is Cyber Security? 

Cyber security is the practice of protecting computers, mobile devices, networks, applications, and digital data from unauthorized access.

Unauthorized access means protected by theft, damage, or cyberattacks. 

It combines tech security processes, and user awareness. That process to keep safe information and ensure that our systems continue to operate securely.

As more of our daily online activities such as banking, shopping, studying, and communication. Due to it the importance of cyber security is growing. Individuals, businesses, schools, and governments all rely on cyber security to protect sensitive information and maintain trust in those services which are provided online.

Why is Cyber Security Important?

Every day, cybercriminals attempt to steal passwords, financial information, personal data, and business secrets. Without proper security measures. These attacks will cause financial losses, identity theft, service disruptions, and damage to an organization’s reputation.

Cyber security is helpful for us:

• Protect personal and business data
• Prevent unauthorized access to our systems
• Reduce the risk of financial fraud or loss
• Ensure websites and applications are running safe
• Protect customer data and privacy
• Support compliance with security and privacy regulations

Example

Imagine you receive an email that appears to be from your bank. The email says:

“Your account has been temporarily locked. Now just Click here to verify your identity.”

The message looks like a real message and that includes the bank’s logo. You click the link and enter your username, password, and one-time verification code.

The user has no idea that it is not a real site and this site is capturing your data.

However, that  website will be fake. That is created by a cybercriminal to copy your bank’s login details. By entering your credentials, you unintentionally give the attacker access to your account.

This type of attack is called phishing.

If your bank uses additional security for getting safe. Such as two step verification or multi-factor authentication, suspicious login detection, and account alerts, and if you recognize the warning signs before entering your information, the attack is much less likely to succeed. This illustrates how cyber security depends on both technical protections and informed user behavior.

Common Types of Cyber Threats

Malware

Malware is malicious software designed to harm devices or steal information. Common forms include viruses, worms, spyware, and Trojans.

Phishing

Phishing attacks trick people into revealing sensitive information through fake emails, websites, messages, or phone calls.

Ransomware

Ransomware encrypts files and demands payment in exchange for a decryption key. Even after payment, there is no guarantee that access will be restored.

Password Attacks

Weak or reused passwords can be guessed, stolen, or exposed in data breaches, allowing attackers to access accounts.

Data Breaches

A data breach occurs when confidential information is accessed or disclosed without authorization, often due to hacking, system vulnerabilities, or human error.

Types of Cyber Security

Network Security

Protects computer networks from unauthorized access and malicious activity using tools such as firewalls and intrusion detection systems.

Application Security

Focuses on making software and web applications secure throughout their development and maintenance.

Information Security

Protects sensitive data from unauthorized access, modification, or destruction, whether the data is stored or transmitted.

Cloud Security

Secures cloud-based infrastructure, applications, and data through proper configuration, access controls, and monitoring.

Endpoint Security
