 For high availability and responsiveness, especially where milliseconds of latency are critical, an engineer must analyze the network’s performance in detail. Total throughput on the interface of the router will provide information on the bandwidth and traffic load, which is essential for understanding if the network can handle the current and projected traffic without delays. NetFlow records are crucial for this analysis as they provide data about the traffic flow across the network, which helps in identifying patterns, peak usage times, and types of traffic. This information is vital for making informed decisions to optimize traffic movement and minimize latency123.

The source IP address from an audit log that indicates a session which may have exploited a vulnerability is considered corroborative evidence. This type of evidence supports other evidence that suggests a security breach occurred. In the context of cybersecurity, corroborative evidence can help establish that an attack was carried out and can be used in conjunction with other data points to build a case during an investigation.

References := The Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) training material discusses the types of data needed to investigate security incidents, which includes understanding the role of different types of evidence in building a security incident case1.

 In Wireshark, to filter traffic for a specific LAN, the correct syntax uses ip.src== and ip.dst== to specify the source and destination IP addresses. The /16 denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range. This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic. References: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.

HTTPS uses SSL/TLS encryption to secure data transmission over the internet. This encryption makes it difficult to monitor HTTPS traffic because the data packets are encrypted making them unreadable to anyone trying to intercept or monitor the data without proper decryption keys. References := Cisco CyberOps Associate
