Network Security Fundamentals

What is a firewall and how does it help in network security?

• A firewall is a type of antivirus software used to protect the network from malware

• A firewall helps in network security by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules.

• A firewall is a physical wall built around the network to prevent unauthorized access

• A firewall is a device used to boost network speed and performance

Explain the concept of defense in depth in network security.

• Defense in depth is a security strategy that is only used for physical security

• Defense in depth is a security strategy that only involves one layer of defense

• Defense in depth is a security strategy that is not effective against any type of attack

• Defense in depth is a security strategy that involves implementing multiple layers of defense to protect the network from various types of attacks.

What are botnets and how do they pose a threat to network security?

• Botnets are harmless networks of computers used for educational purposes.

• Botnets are networks of computers that provide free and secure internet access to users.

• Botnets are networks of private computers infected with malicious software and controlled as a group without the owners' knowledge. They pose a threat to network security by carrying out coordinated attacks, spreading malware, and stealing sensitive information.

• Botnets are networks of computers that enhance network security by detecting and eliminating malware.

What are eavesdropping attacks and how can they be prevented?

• Eavesdropping attacks can be prevented by using unsecured communication channels

• Eavesdropping attacks involve unauthorized interception of communication. They can be prevented by using encryption, implementing secure communication protocols, and using network monitoring tools.

• Eavesdropping attacks can be prevented by sharing sensitive information openly

• Eavesdropping attacks are harmless and do not require any prevention measures

Select the correct three types of network security attacks.

• Data Theft, Malware Attacks, Social Engineering

• Situational Predisposed Panic Attacks, Spontaneous Panic Attacks, MMT

Discuss three types of network security solutions.

• Physical security, Cloud computing, Social media monitoring

• Antivirus software, Password protection, Data encryption

• Biometric authentication, Spam filtering, Data backup

• Firewalls, Intrusion Detection Systems, Virtual Private Networks

Why are security policies and procedures important in network security?

• To establish guidelines and best practices for protecting sensitive information, preventing unauthorized access, and responding to security incidents.

• To increase the risk of security incidents

• To allow unauthorized access to sensitive information

• To make the network slower and less efficient

What are the Cyber Code rules that everyone needs to follow for network security?

• Clicking on all email attachments without caution

• Leaving passwords written on sticky notes

• Never updating software

• Using strong passwords, keeping software updated, being cautious with email attachments, and using a firewall

Explain the concept of security policies in network security.

• A collection of workout routines for office workers

• A set of rules and procedures that define how an organization's information technology and security infrastructure should be managed and protected.

• A list of recommended restaurants for employees

• A set of guidelines for organizing company events

Why is it important to have a strong security policy in place for network security?

• To increase the risk of data breaches and security incidents

• To allow easy access for hackers and cyber criminals

• To make the network slower and less efficient

• To protect sensitive data, prevent unauthorized access, and mitigate security threats.
