Computer Security Flashcards
What is computer security?
Computer security involves protecting computer systems networks and data from unauthorized access attacks and damage.
Name three common security threats.
Common security threats include malware (viruses worms etc.) phishing attacks and denial-of-service (DoS) attacks.
Explain the concept of encryption.
Encryption is the process of converting information into a code to prevent unauthorized access ensuring that only authorized parties can decrypt and access the original data.
What is a firewall?

What is the purpose of antivirus software?
Antivirus software is designed to detect prevent and remove malicious software (malware) from computer systems.
Explain the importance of regular software updates for security.
Regular software updates or patches help fix vulnerabilities in software reducing the risk of exploitation by attackers.
Define social engineering in the context of security.
Social engineering is a tactic used by attackers to manipulate individuals into divulging confidential information or performing actions that may compromise security.
What is a VPN (Virtual Private Network)?
A VPN is a technology that establishes a secure encrypted connection over the internet allowing users to access a private network from a remote location.
Describe the concept of least privilege in security.
The principle of least privilege restricts users and systems to the minimum level of access or permissions necessary to perform their tasks reducing the risk of unauthorized actions.
