Cybersecurity 101: Protecting Your Digital Castle
In today’s interconnected world, cybersecurity has evolved from a niche IT concern to a critical issue impacting everyone. Whether you’re a tech professional, an entrepreneur, or simply someone who uses the internet, understanding cybersecurity is essential. As the host, Brian J. Olds and Ryan Williams Sr. discussed in a recent episode of Tech Tuesday, there are fundamental steps everyone can take to safeguard their digital lives.
The Growing Importance of Cybersecurity
Cybersecurity breaches have become daily headlines. Just recently, Snowflake experienced a significant data breach, reminding us all of the critical importance of cybersecurity. As Ryan pointed out, “It’s not just about IT anymore; everyone has a role to play.” From massive corporations to individual users, no one is immune to the threats posed by cybercriminals.
Ryan emphasized how the perception of cybersecurity has shifted over the years. “Maybe 10–15 years ago, cybersecurity was seen as an IT topic, something for the helpdesk to manage permissions. But now, every day there’s a massive data breach headline,” he explained. This shift underscores the need for everyone to be aware and proactive about cybersecurity.
Common Cybersecurity Threats
Cyber threats come in many forms, including viruses, spyware, worms, and the increasingly prevalent ransomware. Ryan detailed these threats and their potential impacts, emphasizing the importance of good cyber hygiene. “It’s all about having good habits,” Ryan said. “Simple steps like using strong passwords and avoiding suspicious links can make a big difference.”
Social Engineering
One of the most insidious threats is social engineering. Cybercriminals exploit human psychology to trick people into giving away sensitive information. Ryan shared a chilling example: “An elderly gentleman, named William J. Brock, was scammed into handing over $12,000, believing he was helping a family member. It ended tragically when an innocent Uber driver, Lo-Letha Hall, was gunned down in the confusion.” This highlights the need for vigilance and skepticism in all digital interactions.
Ryan also discussed the increasing sophistication of these attacks, especially with the use of AI. “It’s easier to get you on the phone and get you talking about yourself than it is to steal your data by means of being a hacker,” he noted. The human element remains a significant vulnerability in cybersecurity.
The Dark Web
The dark web is often mentioned in the context of cybersecurity, but what exactly is it? Ryan explained that their is only one “internet”. However, the dark web is the part of the World Wide Web that is only accessible by means of special software, allowing users and website operators to remain anonymous or untraceable. This is where illicit activities, including the sale of stolen data, occur. While it’s not easy to remove your data once it’s out there, taking steps like changing compromised passwords and enabling multi-factor authentication can mitigate the risk.
“It’s hard to get your information off the internet in general,” Ryan said. “But if your data is compromised, changing your passwords and using multi-factor authentication can make you a harder target.”
Best Practices for Cybersecurity
Here are some essential cybersecurity practices Ryan recommends:
- Use Strong Passwords: Aim for passwords that are at least 8–12 characters (or more), a combination of upper and lower case letters, numbers, and special characters. Does not use personal information and is unique for every account.
- Enable Multi-Factor Authentication (MFA): This adds an extra layer of security, making it harder for cybercriminals to access your accounts. “I find it annoying, but it has saved my butt so many times,” Ryan admitted.
- Update Software Regularly: Keeping your operating system and applications up-to-date ensures you have the latest security patches. “If you see an update prompt, do it. Nothing can protect you 100% but It’s better to be safe than sorry,” he advised.
- Be Wary of Public Wi-Fi: Use VPNs to encrypt your data when using public networks. “Public Wi-Fi is convenient but risky. A VPN can protect your data from prying eyes,” Ryan warned.
- Educate Yourself and Others: Knowledge is power. Stay informed about the latest threats and share this information with your network. “Cybersecurity is a collective responsibility,” Ryan said. “We need to help each other stay safe.”
Cybersecurity Is Everyone’s Responsibility
During the discussion, Ryan emphasized that cybersecurity is a collective responsibility. Whether you’re protecting personal data or securing a business network, the principles remain the same. As Ryan aptly put it, “Make yourself a harder target.” By implementing these best practices, you can significantly reduce your risk and contribute to a safer digital environment for all.
Ryan’s journey from military IT to cybersecurity expert showcases the importance of continuous learning and adaptation. His transition from supporting the military to educating others through his podcasts, “The Other Side of the Firewall” and “Ask A CISSP,” highlights his dedication to making cybersecurity accessible. “I started the podcast during the pandemic to network and socialize, and it evolved into a platform to showcase and highlight people of color in cybersecurity,” Ryan shared.
