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. A firewall is a vital security device or software sitting between a trusted internal network and an untrusted external network, such as the internet. Its main function is to monitor and control all incoming and outgoing network traffic, ensuring on

Phishing is a type of cyberattack where criminals trick people into giving away sensitive information—like passwords, credit card numbers, or bank account details—by pretending to be a trustworthy source (such as a bank, government agency, or well-known company).

These attacks usually happen through:

• Emails (fake alerts, invoices, or requests to "verify" accounts)

• Text messages (smishing)

• Phone calls (vishing)

• Fake websites that look like real ones

How to Avoid Phishing

Here are some key ways to protect yourself:

1. Check the sender
   Look closely at the email address, phone number, or URL. Phishers often use slight misspellings (e.g., paypa1.com instead of paypal.com).

2. Don’t click suspicious links
   Hover over links to see where they really go before clicking. If unsure, type the website address manually in your browser.

3. Beware of urgent or threatening language
   Messages that say things like “Your account will be closed!” or “Immediate action required!” are common phishing tactics.

4. Never share personal information by email or text
   Legitimate companies will not ask for sensitive data this way.

5. Use security tools

   • Spam filters

   • Antivirus software

   • Multi-factor authentication (MFA) to protect accounts even if a password is stolen

6. Keep software up to date
   Updates often patch security vulnerabilities that attackers exploit.

7. Verify with the source directly
   If you receive a suspicious message, call the company using a trusted phone number (not one in the message).
