False positive and false negative
A false positive is a security alert that flags a threat that does not actually exist, such as a legitimate file marked as malware. A false negative is the opposite and more dangerous: a real threat that gets through without an alert. Tuning rules to reduce both is constant work for a SOC.

CTEM (continuous threat exposure management)
CTEM (continuous threat exposure management) is a program, defined by Gartner, that continuously assesses what a company exposes to attackers, prioritizes what is truly exploitable and validates that fixes work. It follows five stages: scoping, discovery, prioritization, validation and mobilization.
TTP (tactics, techniques and procedures)
TTPs (tactics, techniques and procedures) describe how an attacker operates: the tactic is the goal at each stage, the technique is the method used to reach it and the procedure is the specific way it is carried out. Detecting TTPs works better than chasing single indicators, because an attacker can easily change IP addresses but not the way they operate.
External threat monitoring (cyber patrolling)
External threat monitoring, which TecnetOne calls cyber patrolling, is the continuous monitoring of the internet, social media, forums and the dark web to catch threats against a company early, such as network access for sale, data leaks or attack plans. Unlike digital risk protection (DRPS), which focuses on brand abuse and takedowns, it looks for signs that an attack against the company is being prepared.
Incident response plan
An incident response plan is the document that defines who does what, how people communicate and which steps to follow when a security incident occurs. It includes roles, contacts, escalation criteria, procedures by incident type and notification requirements, and it should be tested with drills.
DRPS (digital risk protection services)
DRPS (digital risk protection services) is a service that monitors the internet, social media, app stores and the dark web for threats against a brand, such as fake websites, impersonating profiles or leaked credentials, and manages takedowns. It protects what lives outside the company's perimeter.
