❓ Frequently Asked Questions
What is cybersecurity?
Cybersecurity is the practice of protecting computer systems, networks, and data from unauthorized access, attacks, and damage through people, processes, and technology.
What is the difference between a threat and a vulnerability?
A threat is a potential danger (e.g., malware, phishing); a vulnerability is a weakness in a system that could be exploited by a threat. Risk combines both the likelihood of exploitation and potential impact.
What is encryption and why is it important?
Encryption turns readable data into unreadable ciphertext so that only authorized parties with the correct keys can read it, protecting data in transit and at rest.
What is risk management in cybersecurity?
Risk management is the process of identifying, assessing, prioritizing, and mitigating cybersecurity risks to reduce potential harm to systems and data.
What are common security protocols?
Security protocols are rules for secure communication, such as TLS/HTTPS for web traffic, SSH for secure remote access, and IPsec for secure network communications.
