Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.

Firewalls improve network security protections in several important ways:

1. Block unauthorized access – Firewalls act as a barrier between your internal network and outside threats, preventing unauthorized users or systems from entering.

2. Filter incoming and outgoing traffic – They monitor data traveling to and from your network and allow only trusted, safe connections based on set rules.

3. Prevent malware communication – Firewalls can stop malicious software from connecting to external servers to steal data or receive commands.

4. Protect sensitive data – By controlling what traffic enters or leaves your network, firewalls help safeguard personal, financial, or business information.

5. Alert you to suspicious activity – Many firewalls provide logs and alerts that notify you of unusual or potentially dangerous behavior.

6. Enforce network policies – You can set rules with a firewall to limit internet access, block harmful websites, or restrict app usage on your network.

7. Reduce risk of cyberattacks – By closing off unused or vulnerable ports and services, firewalls shrink the attack surface hackers can target.
