Information Security

What is the purpose of information security?

• To protect the confidentiality, integrity, and availability of information.

• To make information difficult to access

• To ensure information is always shared with everyone

• To limit the amount of information available

What are the three main goals of information security?

• Confidentiality, Reliability, and Flexibility

• Secrecy, Authenticity, and Accessibility

• Privacy, Accuracy, and Redundancy

• Confidentiality, Integrity, and Availability

What are some common threats to information security?

• Physical security, firewalls, encryption

• Virus, spyware, adware

• Social engineering, password sharing, outdated software

• Malware, phishing, ransomware, insider threats, DDoS attacks

What is the difference between authentication and authorization in information security?

• Authentication determines access rights, while authorization verifies identity.

• Authentication verifies identity, while authorization determines access rights.

• Authentication verifies access, while authorization determines identity.

• Authentication and authorization are the same thing.

What is the role of encryption in information security?

• It protects data from unauthorized access or theft.

• It has no impact on the security of information.

• It makes data more easily accessible to unauthorized users.

• It slows down the processing speed of the system.

What is a firewall and how does it contribute to information security?

• A firewall is a type of physical barrier used to protect information from physical theft

• A firewall contributes to information security by allowing all types of traffic to pass through without any filtering

• A firewall is a software used to enhance the speed of internet connection

• A firewall contributes to information security by filtering and blocking potentially malicious or unauthorized traffic, thus protecting the network from cyber attacks and unauthorized access.

What are some best practices for maintaining information security?

• Never updating software and leaving it vulnerable

• Regular software updates, strong password policies, data encryption, employee training, and implementing access controls

• Storing data without any encryption or protection

• Using simple and easily guessable passwords

What is the importance of regular software updates in information security?

• Regular software updates are not important for information security

• There is no need for software updates as long as the antivirus is up to date

• Regular software updates are important for fixing security vulnerabilities and bugs, improving system performance, and protecting against new threats.

• Software updates can slow down the system and cause more issues

What are the potential risks of using public Wi-Fi networks for transmitting sensitive information?

• Reducing the risk of identity theft

• Exposing sensitive information to potential hackers or unauthorized users

• Improving network performance

• Enhancing data security
