False positives and false negatives are terms used to describe the accuracy of security alerts. A false positive occurs when a security system incorrectly identifies benign activity as malicious, leading to unnecessary investigation and potential disruption of legitimate activities. Conversely, a false negative happens when a security system fails to detect actual malicious activity, allowing the attackers to proceed undetected. The impact of false positives is generally wasted time and resources investigating non-issues, while the impact of false negatives can be much more severe, potentially leading to undetected breaches and significant damage.

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

• A Distributed Denial of Service (DDoS) attack involves multiple compromised devices (botnet) sending a large number of requests to a target server to overwhelm it.
• In a specific type of DDoS attack known as an NTP amplification attack, the attacker exploits the Network Time Protocol (NTP) servers by sending small queries with a spoofed source IP address (the target’s IP).
• The NTP server responds with a much larger reply to the target’s IP address, thereby amplifying the traffic directed at the target.
• This reflection and amplification technique significantly increases the volume of traffic sent to the target, causing denial of service.
