After a recent audit, a company was advised to segregate their network to ensure sensitive data isn't accessible to all employees. Which network security best practice is being recommended?
- DMZ (Demilitarized Zone)
- IP Address Spoofing
- Network Segmentation
- Port Forwarding
Network Segmentation involves dividing a network into segments to restrict access, reducing the risk of unauthorized access to sensitive data and improving security.
An IDS that actively takes actions, such as blocking traffic or terminating sessions, when a threat is detected is referred to as _______.
- Firewall
- Honeypot
- Intrusion Prevention System
- Router
An Intrusion Prevention System (IPS) is an IDS that not only detects threats but also takes proactive measures to block or prevent them.
Bob receives an email with a link to a site that looks like his bank's website. When he enters his credentials, they are sent to an attacker instead of the bank. While the real bank's site was not compromised, what kind of attack did Bob fall victim to?

- Man-in-the-Middle Attack
- Phishing Attack
- SQL Injection
Bob fell victim to a Phishing Attack, where he was deceived into entering his credentials on a fake site. The bank's site itself wasn't compromised.
When employees fail to report security incidents due to fear of reprisal, it's often a sign of a weak _______ culture.
- Compliance
- Ethical
- Organizational
- Security
When employees fail to report security incidents due to fear of reprisal, it's often a sign of a weak organizational culture. A strong security culture encourages employees to report incidents without fear of negative consequences and emphasizes the importance of security.
After adopting a new BYOD policy, a company notices an increase in security incidents related to mobile devices. What might be an effective measure to decrease these incidents while still allowing BYOD?
- Ban BYOD entirely
- Decrease the security awareness training
- Implement Mobile Device Management (MDM) solutions
- Increase the number of personal devices allowed
Implementing Mobile Device Management (MDM) solutions can be an effective measure to decrease security incidents related to mobile devices while still allowing BYOD. MDM solutions provide better control and security for company data on personal devices, allowing for features like remote wipe, device encryption, and app management to mitigate risks.
The process of continuously monitoring systems for vulnerabilities and applying necessary patches is known as _______.
- Firewall Configuration
- Intrusion Detection
- Penetration Testing
- Vulnerability Management
Vulnerability Management involves the systematic process of identifying and addressing vulnerabilities in a network or system. It includes vulnerability scanning, assessment, and patch management to ensure that the system is protected from known vulnerabilities.
The process of allowing certain traffic to bypass the usual security inspection based on specific criteria is known as firewall _______.
- Bypass
- Exception
- Exemption
- Whitelisting
Firewall 'Exception' allows specific traffic to bypass regular security inspection, based on predefined criteria or exceptions.
Jane, a network administrator, notices that a server's SSL certificate has expired. If the certificate isn't renewed, what could be a potential impact on the server's users?
- Users will experience SSL errors while connecting to the server.
- Users will have slower internet access.
- Users will lose access to the server.
- Users will need to update their passwords.
An expired SSL certificate will result in SSL errors, which can disrupt secure connections, leading to a loss of trust and potential security risks for the server's users.
_______ provides a way to ensure the integrity of data stored on disk by verifying that it hasn't been tampered with.
- Firewall
- Hashing
- Proxy
- RAID
Hashing provides data integrity by producing a fixed-size hash value (digest) based on the content of the data. If the data changes, the hash value will also change, making it easy to detect any tampering or corruption.
Regularly scheduled backups that only capture the data that has changed since the last full backup are known as what?
- Differential Backups
- Full Backups
- Incremental Backups
- Mirror Backups
Incremental Backups capture only the data that has changed since the last backup, whether it was a full backup or a previous incremental backup. This reduces the backup time and storage space needed.
