Cybersecurity: A STEM Career to Consider

In today's digital age, Cybersecurity (also known as IT security) plays a crucial role in safeguarding computer systems, servers and networks from malicious cyber attacks.

As cyber threats continue to evolve, understanding the landscape of cybersecurity is very essential for both individuals and organizations.

Cyber Threats

Cyber threats refer to illegal attempts to access, steal or damage data. It is often executed by hackers, criminal organizations, spies, terrorist groups or even hostile nations.

Here are some of the most prevalent cyber threats:

• Denial of Service (DoS) & Distributed Denial of Service (DDoS) Attacks: System overload disrupting its services.

• Spam: Unwanted or unsolicited emails and messages.

• Botnets: Networks of infected devices used for malicious activities.

• Malware: Software such as viruses, worms, and trojans designed to harm systems.

• Phishing: Deceptive communications designed to trick individuals into revealing personal information.

• Ransomware: Software that encrypt data and demands payment for decryption.

• Spyware: Software that secretly monitors user activities without permission.

Key Cyberattack Targets

• Financial Systems: Banks and Online payment platforms.

• Government Agencies: Sensitive government data and operations.

• Large Corporations.

• Consumer Devices: Personal devices like smartphones and computers.

Essential Cybersecurity Practices

To protect against cyber threats, consider implementing the following measures:

• Regular Software Updates: Keep software and operating systems up-to-date to patch vulnerabilities.

• Strong Passwords: Use complex and unique passwords for your different accounts.

• Cautious Email Practices: Avoid clicking on links or opening attachments from unknown senders.

• Antivirus Software: Install and maintain reputable antivirus programs.

• Secure Wi-Fi Usage: Avoid using unsecured public Wi-Fi networks.

In-Demand Cybersecurity Skills

The evolving cybersecurity landscape demands professionals with the following skills:

• Programming: Understanding coding to identify and mitigate vulnerabilities.
