Safeguard Principles and Mechanisms | Part 2

Introduction

Continuing the discussion on providing adequate cybersecurity, there are other ways in which we provide a solution. Gaining insights into anti-malware tools that protect against harmful software, firewalls that defend digital entry points, and intrusion detection systems that act as digital watchmen against unauthorized access.

Knowledge Point

In today's digital age, ensuring the security of networks has become increasingly important.

In fact, in 2023, over 353 million individuals were affected by data compromises, in which sensitive data was  accessed by unauthorized parties. (Reference: Statista)

As more and more sensitive information is shared online, it's becoming increasingly critical for businesses and organizations to protect their networks from cyber threats. Taking that extra step to ensure security through understanding the functions of VPNs, firewalls, and IDS is crucial in safeguarding networks against cyber threats.

Firewall 🔥

  • A network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
  • Firewalls allow or block network traffic between devices based on rules set up by the firewall administrator. Each rule defines a specific traffic pattern that you want the firewall to detect and the action that you want the firewall to take when that pattern is detected.

Intrusion Detection and Intrusion Prevention Systems 🔔

  • Intrusion Detection System (IDS) is a network security tool that monitors network traffic and devices for known malicious activity, suspicious activity, or security policy violations. Whereas an IDS is designed to detect and report suspicious network traffic, an
  • Intrusion Prevention System (IPS) goes one step further by monitoring network traffic for potential threats and automatically blocks them by alerting the security team, terminating dangerous connections, removing malicious content, or triggering other security devices.

Virtual Private Network 💻

  • A communications session between devices that can safely traverse public networks and has been made virtually private through the use of encryption technology.
  • Establishes a digital connection between your computer and a remote server, creating a point-to-point tunnel that encrypts your personal data, masks your IP address, and lets you sidestep website blocks and firewalls on the internet.

Think of when game developers for your popular online games rely on mechanisms such as firewalls, IDSs, IPSs, and VPNs to secure online gaming servers. These tools help prevent cheating, protect player data, and ensure fair gameplay experiences for gamers around the world. So it is safe to say that it is beneficial to consider to ensure additional layers of security measures.

Reflection

In the current digital era, network security is paramount to protect sensitive information shared online. Understanding Virtual Private Networks (VPNs), firewalls, and Intrusion Detection Systems (IDS) is crucial for organizations to safeguard against cyber threats. Firewalls monitor and control network traffic based on security rules, while IDS detects malicious or suspicious activity and IPS takes action to block threats. VPNs establish secure connections over public networks, encrypting data and allowing users to bypass restrictions for a safer online experience.
