Cybersecurity is crucial because it protects sensitive data, systems, and networks from cyber threats like hacking, malware, ransomware, and data breaches.
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.\Phishing is a type of cyberattack where attackers try to trick you into giving up sensitive information—like usernames, passwords, credit card numbers, or personal data—by pretending to be a trustworthy entity. It often happens via email, but can also occur through text messages (smashing), phone calls (vishing), or fake websites.
The main difference between a virus and a worm lies in how they spread and how they operate:
🔬 Virus
-
Needs a host file or program to spread.
-
It attaches itself to executable files (like
.exe) or documents. -
Spreads when the infected file is opened or executed.
-
Often spreads via email attachments, file downloads, or removable media.
-
Can corrupt or delete files, or damage system functions.
Analogy: Like a parasite that needs a host to survive and reproduce.
🐛 Worm
-
Self-replicating and self-spreading—does not need a host file.
-
Can spread automatically through networks (e.g., via security flaws).
-
Often spreads rapidly across systems without user action.
-
Typically causes network congestion, slows down systems, or installs backdoors.
Analogy: Like an independent creature that burrows through systems on its own.
Summary Table:
| Feature | Virus | Worm |
|---|---|---|
| Needs a host file? | Yes | No |
| User action needed? | Usually | Often no |
| Spread method | File attachments, infected apps | Network, exploits, auto-replication |
| Damage type | Corrupts files, system damage | Network overload, spreading malware |
