Network Security Best Practices

The video tutorial discusses the importance of network monitoring to protect systems from attackers. It covers the use of Security Information and Event Management (SIEM) systems to consolidate logs and generate reports. The tutorial also highlights the need for vulnerability management and the challenges of detecting and responding to security incidents. It emphasizes the importance of real-time alerts and accurate incident detection to maintain network security.

Why is real-time monitoring crucial for network security?

• To react promptly to security events

• To ensure all employees are working

• To reduce network traffic

• To increase system performance

What could be a cause for concern when monitoring network logins?

• Logins with strong passwords

• Logins from an unexpected country

• Logins during work hours

• Logins from known locations

What is a potential indicator of data exfiltration?

• A decrease in network traffic

• A sudden spike in data transfer

• A consistent data transfer rate

• A drop in data transfer speed

Why is it important to keep communication open with software developers?

• To learn new programming languages

• To increase software sales

• To get discounts on software

• To receive updates on security issues

What is the primary function of a SIEM system?

• To block unauthorized access

• To consolidate and analyze log data

• To manage user accounts

• To increase network speed

How can organizations manage vulnerabilities in mobile devices?

• By restricting internet access

• By constantly scanning and reporting

• By using antivirus software

• By disabling all mobile devices

What is the purpose of actionable reports in vulnerability management?

• To entertain IT staff

• To identify and address non-compliant devices

• To reduce the number of devices

• To increase network traffic

What is a false positive in the context of network alerts?

• An alert that is ignored by the system

• An alert that correctly identifies a threat

• An alert that fails to trigger

• An alert that incorrectly signals a threat

What is the benefit of having a long-term backup strategy?

• To ensure data is always available

• To reduce storage costs

• To improve network speed

• To mitigate the impact of undetected breaches

What is a common reaction to a network security alarm?

• Shutting down the entire network

• Notifying all employees

• Quarantining the affected system

• Ignoring the alarm
