Software security is designed to protect systems and data from various types of communication

threats. These threats can be categorized as:

Intentional Attacks: These are deliberate actions taken by malicious individuals or groups aiming to

exploit software vulnerabilities for gain, disruption, or espionage. Examples include hacking,

phishing, and malware attacks.

Unintentional Attacks: These are accidental events that can cause security breaches, such as user

errors or software bugs.

Physical Attacks: These involve physical actions against hardware that can affect software, like theft

or damage.

Natural Disasters: Events such as earthquakes or floods that can physically damage systems and

cause software failures.

Among these, software security primarily addresses intentional attacks. The focus is on preventing

unauthorized access, data breaches, and other forms of cyber attacks.
