Accounting tracks user activities (e.g., logging access times).
Example: A user logs in (Authentication), accesses a file (Authorization), and their actions are logged (Accounting).

Q2. Best practice of cyber security

Ans.

Implementing multi-layered defense mechanisms, regular security updates, employee training, and incident response planning are key cyber security best practices.

Q7. Different types of attacks

Ans.

Different types of attacks include phishing, malware, DDoS, and social engineering.

Phishing: fraudulent emails or websites to trick users into revealing sensitive information
Malware: malicious software designed to harm or exploit a computer system
DDoS: Distributed Denial of Service attacks overwhelm a system with traffic, causing it to crash
Social engineering: manipulating individuals into divulging confidential information

Q8. IDS vs IPS

Ans.

IDS detects intrusions, while IPS actively prevents them, enhancing network security.

IDS (Intrusion Detection System) monitors network traffic for suspicious activity.
IPS (Intrusion Prevention System) not only detects but also blocks potential threats.
Example of IDS: Snort, which analyzes traffic and alerts administrators.
Example of IPS: Cisco Firepower, which can block malicious traffic in real-time.
IDS is typically passive, while IPS is active in protecting the network.
