Spotting and Handling Common Cybersecurity Threats in Everyday IT Work – A Practical Guide from an IT Technician

In my role as a Junior IT Technician with over three years of experience supporting staff in education and public sector environments, I've seen firsthand how common digital threats can disrupt operations and put sensitive information at risk. From troubleshooting PCs and networks at Chief Luthuli Primary School (where I supported over 60 staff members) to managing backups and confidential data like payroll records, learner information, and job-seeker details in government projects, one thing is clear: basic awareness and quick action make a big difference.
I completed IBM's "Identify and Investigate Cybersecurity Threats" certification in 2021, which gave me structured knowledge of threat types and investigation steps. This guide shares practical ways to spot and handle everyday threats—especially useful for small teams, schools, NGOs, or anyone handling personal or confidential data.

  1. Common Threats You Might Encounter Daily

Phishing Emails and Fake Messages
Attackers send emails or messages pretending to be trusted sources (e.g., your bank, Microsoft, or a colleague) to trick you into clicking links or sharing login details. In my school role, suspicious emails sometimes targeted staff during busy periods.
Malware from Downloads or USB Drives
Opening infected files or plugging in unknown USBs can install ransomware, spyware, or viruses that steal data or lock systems. I've dealt with slow PCs caused by hidden malware.
Weak Passwords and Unsecured Wi-Fi
Reusing simple passwords or connecting to public/open Wi-Fi exposes accounts and data. Domain environments I worked in highlighted how one weak link affects the whole network.
Unpatched Software and Outdated Systems
Not updating Windows, browsers, or apps leaves known vulnerabilities open. I've resolved issues by forcing updates during maintenance.

2.** How to Spot These Threats Early**

Unusual system behavior: Slow performance, unexpected pop-ups, or programs opening/closing on their own (common signs from my troubleshooting experience).
Suspicious emails: Check sender address carefully (e.g., "support@microsoft.com" vs. "support@micr0soft.com"), hover over links without clicking, avoid urgent demands for info.
Login alerts or failed attempts: If you get notifications of logins from unknown locations, act immediately.
Data changes or missing files: Regular backups helped me notice anomalies quickly in asset registers and documentation.

  1. Practical Steps to Handle and Mitigate Threats

Verify Before Acting
Don't click links in unexpected emails—go directly to the official site (e.g., type office.com yourself). For attachments, scan with antivirus first.
Use Strong, Unique Passwords + 2FA
Enable two-factor authentication (2FA) wherever possible, especially on Microsoft 365 accounts. Use a password manager if managing many logins.
Keep Everything Updated
Set Windows and apps to auto-update. In my roles, regular patching prevented many issues.
Secure Backups and Access Controls
Perform regular system backups (as I did for IT assets and digital docs). Limit access to sensitive data—only give permissions needed (e.g., payroll files restricted to admin).
Run Antivirus and Scans
Use built-in Windows Defender or free tools; schedule weekly scans. Report anything suspicious to your IT team right away.
Basic Incident Response
If you suspect a breach: Disconnect from the network, don't shut down (preserves evidence), change passwords from a clean device, and notify responsible parties.

**Why This Matters for Everyday Users
**In environments like schools or community projects, a single breach can expose personal data of students, staff, or job-seekers—leading to identity theft or privacy violations. Simple habits reduce risks dramatically, protecting both individuals and organizations.
By applying these basics from my daily IT support work and IBM training, you can build stronger defenses without advanced tools. Stay vigilant—cyber threats evolve, but awareness is your first line of defense.
