What is Cyber Security?

Cyber security, also known as information technology security, is the practice of protecting networks, systems, and programs from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Cyber security includes a variety of security measures, such as firewalls, encryption, and authentication, that are used to protect networks, systems, and programs from unauthorized access.

Seven Pillars of Cyber Security?

Cyber security is a wide field covering several disciplines. It can be divided into seven main pillars:

1. Access Control: Establishing and maintaining secure access to systems and data.

2. Network Security: Protecting networks from malicious activity and unauthorized access.

3. Data Security: Ensuring the confidentiality, integrity, and availability of data.

4. Identity and Access Management: Managing user identities and access rights.

5. Endpoint Security: Protecting endpoints from malicious activity and unauthorized access.

6. Application Security: Securing applications from malicious activity and unauthorized access.

7. Cloud Security: Ensuring the security of cloud-based systems and data.

Different types of Cyber Security categories

1. Network Security: This involves protecting networks from unauthorized access, malicious attacks, and other threats.

2. Application Security: This involves protecting applications from malicious attacks, such as SQL injection, cross-site scripting, and other threats.

3. Data Security: This involves protecting data from unauthorized access, malicious attacks, and other threats.

4. Endpoint Security: This involves protecting endpoints, such as computers, mobile devices, and other devices, from malicious attacks, viruses, and other threats

5. Cloud Security: This involves protecting cloud-based services and data from malicious attacks, unauthorized access, and other threats.

6. Identity and Access Management: This involves managing user identities and access to systems, networks, and applications.

7. Risk Management: This involves assessing and managing risks associated with cyber security threats.

8. Incident Response: This involves responding to and mitigating the effects of cyber security incidents.

9. Education and Awareness: This involves educating users on cyber security best practices and raising awareness of cyber security threats.

10. Compliance: This involves ensuring that organizations comply with applicable laws and regulations related to cyber security.

11. Disaster Recovery: This involves developing plans and procedures to recover from cyber security incidents.

12. Cryptography: This involves using encryption and other cryptographic techniques to protect data and communications.

13. Penetration Testing: This involves testing systems and networks for vulnerabilities and weaknesses.

14. Security Monitoring: This involves monitoring systems and networks for suspicious activity and potential threats.

15. Software Security: This involves protecting software from malicious attacks, vulnerabilities, and other threats.

16. Hardware Security: This involves protecting hardware from malicious attacks, tampering, and other threats.

17. IoT Security: This involves protecting Internet of Things (IoT) devices from malicious attacks, unauthorized access, and other threats.

18. Artificial Intelligence Security: This involves protecting AI systems from malicious attacks, data manipulation, and other threats.

19. Automation Security: This involves protecting automated systems from malicious attacks, unauthorized access, and other threats.

20. Physical Security: This involves protecting physical assets from theft, vandalism, and other threats.

21. Supply Chain Security: This involves protecting the supply chain from malicious attacks, data breaches, and other threats.

22. Privacy: This involves protecting user data and ensuring that it is handled responsibly and securely.

23. Governance: This involves establishing policies and procedures to ensure that cyber security measures are implemented and maintained.

24. Auditing: This involves assessing systems and networks for compliance with applicable laws and regulations.

25. Legal: This involves understanding and complying with applicable laws and regulations related to cyber security.

What Is a Cyber Security Threat?

Cyber security threats are malicious attempts to gain access to, disrupt, or damage computer systems, networks, or devices. These threats can come in the form of viruses, malware, ransomware, phishing, and other malicious activities.

What are the different types of Cyber Threats?

The different types of cyber security threats include

  • Malware
  • Ransomware
  • Distributed denial of service (DDoS) attacks
  • Spam and Phishing
  • Corporate Account Takeover (CATO)
  • Automated Teller Machine (ATM) Cash Out
  • Social engineering attacks
  • Software supply chain attacks
  • Advanced persistent threats (APT)
  • Man-in-the-middle attack (MitM)

Emerging information security threats and challenges in 2023

  • Use of artificial intelligence (AI) by attackers
  • Cybersecurity skills gap
  • Vehicle hacking and Internet of Things (IoT) threats
  • Threats facing mobile devices
  • Cloud security threats
  • State-sponsored attacks

Cyber safety tips – How to protect yourself against cyberattacks

By using strong passwords, enabling two-factor authentication, keeping the software and operating systems up to date, using secure networks, avoiding suspicious links and emails, backing up data regularly, and monitoring online activity.

Use Strong Passwords

Did you know the most commonly used password is “password”? Followed by “123456789”? Using your child’s name or your name with their birthday isn’t much better.   

Picking a password that is easy is like locking your door but hanging the key on the doorknob. Anyone can get in.   

Here are some tips for creating a stronger password. Make sure it’s: 

  • long – your password should be at least 15 characters,  
  • unique – Password should be never used anywhere else, 
  • and randomly generated – usually by a computer or password manager. They’re better than humans at being random. You can use the LastPass Password generator to create randomly generated unique passwords.

Make sure you’re not recycling the same password across all your apps and websites. You can use a password manager to store all of your passwords. That way you don’t have to remember them all! If you go this route, make sure your master password is strong and memorable, and secure your password manager account with MFA! 

Enabling Two-Factor Authentication

People call it by many names: Two Factor Authentication. Multifactor Authentication. Two-Step Factor Authentication. MFA. 2FA. They all mean the same thing: opting into an extra step when trusted websites and applications ask you to confirm you’re really who you say you are.    

Update your software.

Bad actors will exploit flaws in the system. Network defenders are working hard to fix them as soon as they can, but their work relies on all of us updating our software with their latest fixes.  

Update the operating system on your mobile phones, tablets, and laptops. And update your applications – especially the web browsers – on all your devices too.   Leverage automatic updates for all devices, applications, and operating systems.     

At home, automate software updates and periodically restart your devices to ensure that updates are fully installed.

Think before you click

Even if an email looks like it’s from someone you know, take care with attachments. Take that extra second to avoid walking into a digitally dangerous situation. Don’t reply to the email because the sender’s identity might have been compromised.
