What is Cyber Security | Definition, Types and Safety Tips


Cyber Security


Definition of Cyber Security

Cyber security is the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Also referred to as information technology security or electronic information security. The term applies in a variety of situations, from business to mobile computing, and can be divided into several general categories.

Types of cyber security

Critical Infrastructure Security: Consists of cyber-physical systems such as power grids and water purification systems.

Network Security: Protect your infrastructure by protecting your internal network from intruders. Examples of network security include implementing two-factor authentication (2FA) and strong new passwords.

Application Security: Use software and hardware to protect against external threats that may emerge during application development. Examples are antivirus programs, firewalls, and encryption.
Information Security: Also known as InfoSec, it protects both physical and digital data (basically any form of data) from unauthorized access, use, modification, disclosure, deletion, or other fraudulent activities.

Cloud Security: A software-based tool that protects and monitors data in a cloud to help eliminate the risks associated with on-premises attacks.

Data Loss Prevention: consists of developing policies and processes to handle and prevent data loss and developing recovery policies in the event of a cybersecurity breach. This includes setting data storage network permissions and policies.

End-user education: We recognize that cybersecurity systems are potentially the weakest links, that is, as strong as the people who use them. Educating end users includes teaching users to follow best practices such as not clicking unknown links or downloading suspicious attachments in emails.

Types of cyber threats

Malware: Malicious software such as computer viruses, spyware, Trojan horses, and keyloggers.
Ransomware-malware that locks or encrypts data until the ransom is paid.

Phishing Attacks: The act of obtaining sensitive information (passwords, credit card information, etc.) via spoofed emails, phone calls, or text messages.

Social Engineering: Personal psychological manipulation to obtain sensitive information. Often overlaps with phishing.

Advanced Persistent Threat: An attack in which an unauthorized user gains access to a system or network and is not detected for an extended period of time.

Cyber Security Safety Tips 

Update your software and operating system: The latest security patches are available.

Use antivirus software and Update your software for the highest level of protection.

Use strong passwords: Prevent passwords from being easily guessed.

Do not open email attachments from unknown senders. These may be infected with malware.

Don't click links in emails from unknown senders or strange websites. This is a common way to spread malware.

Do not use insecure WiFi networks in public places. Insecure networks are vulnerable to mid-range attacks.
