Insufficient Logging and Monitoring

The video discusses the challenges in detecting cyber attacks, which often go unnoticed for long periods. It highlights the importance of logging and monitoring activities to identify suspicious behavior. Examples of insufficient logging, such as failed login attempts and DNS traffic spikes, are provided. The video concludes with protective measures, emphasizing the need for effective security procedures and regular testing.

Why is it crucial to log and monitor all activities in a system?

• To reduce the cost of system maintenance

• To ensure system performance is optimal

• To detect malicious activities and prevent attacks

• To comply with international standards

What is a sign of insufficient logging?

• Low network latency

• Multiple failed login attempts from one source

• Consistent traffic patterns

• A single failed login attempt

Why is it important to monitor DNS traffic?

• DNS traffic can be used to bypass firewall controls

• DNS traffic is always secure

• DNS traffic is irrelevant to security

• DNS traffic is only used for internal communications

What should be in place to handle security incidents effectively?

• A strong password policy

• An effective security incident response procedure

• Regular software updates

• A dedicated IT support team

What is a common method attackers use to bypass firewall controls?

• Using strong encryption

• Injecting malicious queries within legitimate DNS queries

• Disabling antivirus software

• Changing network configurations
