Alert fatigue

Alert Fatigue, otherwise known as alarm fatigue, occurs usually when a SOC analyst is vulnerable to a large number of frequent alarms (alerts) and consequently becomes desensitized to them. Desensitization usually results in longer response times and/or missing important alerts from malicious activity. A large number of those alerts are not, in fact, real threats […]

Anomalies and alerts

Anomalies are deviations from a normal pattern in one or more parameters that signal unexpected behavior. Anomalies are not, by definition, good or malicious. They are simply unexpected reactions. An anomaly could be an abnormally high number of users logging in as well an unusually low number. If bandwidth use spikes suddenly beyond what would […]

Anomaly Detection

In data mining, anomaly detection (also known as outlier detection) is the recognition and identification of unusual items, events or observations which raise suspicions by containing significant differences from the rest of the data. Usually, the anomalous items will translate to some sort of issues like bank fraud, a structural defect, errors in a text, […]

Automated Alert Prioritization

Automated alert prioritization ensures the most significant threats get the highest level of attention. It does this by flagging high-level threats so the threats that really matter are shown first to the SOC team to allow for a faster response time and therefore faster remediation. By sending actionable alerts to analysts based on tier, analysts […]

Automated Detection

Automated detection is referred to when artificial intelligence (AI) and a subset of AI known as machine learning, is used to automate the detection process. The importance of this process is that algorithms will work around the clock (all day every day 24/7) to find, identify and alert security personnel about suspicious or unusual network […]

Automated Investigation

Automated Investigation helps ensure analysists have a complete and accurate set of data when they handle a threat. It can also significantly reduce the alert fatigue caused by noisy legacy threat detection systems by ensuring all alerts that are sent to the SOC team are worthy of their time. It also reduces the dwell time […]

Automated Playbooks

Automated playbooks are the process of creating workflows with machine-understandable codification to enable automation of the procedures. After the code is created, orchestration services execute workflows by interfacing with the other orchestration services and humans as necessary. This goal of this is to maximize the efficiency of the SOC and better response times by allowing […]

Automated response

Automated response is pre-configured by the system to respond to and mitigate cyber threats. This means that as soon as the detection system flags incoming communications as malicious, the system responds to the threat without the intervention of security personnel, decreasing response time dramatically to better protect the organization. Since the security team must first […]

Threat intelligence is evidence-based knowledge, including context, mechanisms, indicators, implications and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject’s response to that menace or hazard. It allows you to effectively mitigate attacks. The three subcategories of threat intelligence are strategic, operational, […]

Undetected threats

Undetected threats are malicious communications and activities that the organization’s Security Information and Event Management (SIEM) fails to identify and alert the security operation’s team about in the network. That failure is also called a false negative because the SIEM doesn’t catch the threat and deems it benign. Undetected threats can lead to long-dwell breaches […]
