What is Cybersecurity?

Cybersecurity refers to the practices and technologies used to protect computer systems, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction.

What are some common cybersecurity problems?

Major security problems in cybersecurity can include unauthorized access, data breaches, malware infections, Denial-of-Service attacks, and phishing scams.

What are the main types of hackers?

Hackers can be categorized into different types, including:

  • Black Hat: Malicious hackers who exploit vulnerabilities for personal gain.
  • White Hat: Ethical hackers who use their skills to identify and fix security weaknesses.
  • Gray Hat: Hackers who may engage in both ethical and unethical activities, blurring the lines.

What are some solutions to cybersecurity problems?

Expected solutions for security problems in cybersecurity often include:

  • Strong passwords: Using complex and unique passwords for each online account.
  • Multi-factor authentication: Adding extra layers of security by verifying identity through different methods.
  • Security software: Installing and updating anti-virus and firewall programs.

Introduction

  • Cyber security is the protection of online information.
  • The increasing use of the internet leads to more security threats.

Fundamentals of Cyber Security

  • Cyber: Refers to information technology, the internet, and virtual reality.

Need for Cyber Security

  • Cyber security protects data from theft, misuse, and viruses.

Major Security Problems

  • Viruses
  • Hackers
  • Malware
  • Trojan horses
  • Password cracking

Viruses and Worms

  • Viruses are programs that load onto computers without user knowledge and act against user wishes.

Solutions

  • Install a security suite that protects computers from threats.

Hackers

  • Hackers are people who break into computers, usually through administrative controls.

Preventing Hacking

  • Implementing effective security controls, such as strong passwords and firewalls, is key.

Malware

  • Malware encompasses malicious software that infects/damages computer systems.
  • Malware examples include Rootkits, Worms, Spyware, Trojans, Viruses, Crimeware, and Adware.

Stopping Malware

  • Download anti-malware programs to prevent infections.
  • Activate network threat protection, firewalls, and antivirus.

Trojan Horses

  • These are email viruses that replicate, steal info, or harm systems.
  • They are among the gravest threats to computers.

Avoiding Trojans

  • Use security suites, like Avast Internet Security, to prevent downloading them. This is a useful illustrative example provided.

Password Cracking

  • Hackers employ attacks to gain access to passwords on protected systems and social media sites.

Securing Passwords

  • Use strong passwords.
  • Never reuse the same password for different accounts.

Cyber Security Responsibility

  • Cyber security is a collective responsibility, involving everyone.
