Blog Post #6 – Network Security

 By Joseph Dugan

In today’s digital world, protecting information systems is more critical than ever. Both individuals and organizations rely on secure networks to safeguard personal data, financial records, and business operations. Unfortunately, cyber threats like computer viruses and social engineering attacks continue to exploit system and human vulnerabilities.

Even basic tools, such as the ping command, can be used maliciously. Attackers may launch a Ping Flood or Smurf Attack to overwhelm networks, causing a denial-of-service attack and disrupting traffic.

Threat 1: Computer Viruses

Viruses spread through infected files, unsafe downloads, or outdated software. They can slow down systems, delete data, or even encrypt files for ransom.
Prevention tips:

• Use up-to-date antivirus software.

• Regularly apply system patches and updates.

Threat 2: Social Engineering

These attacks trick users into revealing private information, often through phishing emails or impersonation. The 2020 Twitter breach is a prime example of the damage social engineering can cause.
Prevention tips:

• Train users to recognize scams.

• Implement multi-factor authentication (MFA) for added protection.
