Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches.  

Phishing is a type of cyber attack where attackers impersonate trusted sources (like banks, companies, or coworkers) to trick individuals into revealing sensitive information such as passwords, credit card numbers, or login credentials.


🎣 How Phishing Works:

Attackers often use:

  • Emails: Fake messages with malicious links or attachments.

  • Text messages (Smishing): Urgent alerts that ask you to click a suspicious link.

  • Phone calls (Vishing): Scammers posing as support agents or officials.

  • Fake websites: Look-alike sites that steal your login details.


🚫 How to Prevent Phishing Attacks:

1. Be Cautious with Links

  • Hover over links before clicking to see the real URL.

  • Avoid clicking on links in unexpected emails or texts.

2. Verify the Sender

  • Look for misspellings, strange email addresses, or suspicious language.

  • Contact the sender directly using a trusted method if something seems off.

3. Use Multi-Factor Authentication (MFA)

  • Even if credentials are stolen, MFA helps block unauthorized access.

4. Keep Software Updated

  • Regular updates fix security flaws that phishing malware can exploit.

5. Use Anti-Phishing Tools

  • Email filters, browser extensions, and antivirus software can block phishing attempts.

6. Educate and Train Users

  • Regular training helps employees and individuals recognize and report phishing.

7. Don’t Share Sensitive Info Over Email or Phone

  • Legitimate organizations won’t ask for passwords or financial info via email or call.
