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. 

Antivirus software detects threats using a combination of several techniques, each designed to identify malicious software (malware) in different ways. Here’s a breakdown of the main detection methods:

---

1. Signature-Based Detection

• How it works: Compares files and programs to a database of known malware “signatures” (unique strings of code or behavior).

• Pros: Fast and accurate for known threats.

• Cons: Ineffective against new or unknown (zero-day) threats until their signatures are added.

---

2. Heuristic Analysis

• How it works: Analyzes code behavior or structure for suspicious characteristics, even if the exact code hasn't been seen before.

• Pros: Can catch new or modified malware variants.

• Cons: Higher risk of false positives (flagging legitimate software as malicious).

---

3. Behavioral Detection

• How it works: Monitors running programs in real time for suspicious activity, like trying to modify system files, connect to remote servers, or encrypt large numbers of files (as ransomware would).

• Pros: Good for catching threats missed by signature and heuristic methods.

• Cons: Can be resource-intensive and may also cause false positives.

---

4. Sandboxing

• How it works: Runs suspicious files in a virtual, isolated environment (a “sandbox”) to observe what they do without risking the actual system.

• Pros: Helps detect deeply hidden or dormant threats.

• Cons: Slower and may miss malware that behaves differently in sandbox environments.

---

5. Cloud-Based Detection

• How it works: Sends unknown files or behaviors to the vendor’s cloud for deeper analysis using big data and AI models.

• Pros: Offers up-to-date threat intelligence and more processing power.

• Cons: Depends on internet connectivity and may raise privacy concerns.

---

6. Machine Learning and AI

• How it works: Uses trained models to classify programs as safe or malicious based on patterns learned from vast datasets.

• Pros: Improves over time and adapts to new types of threats.

• Cons: Complex to implement and sometimes less transparent.
