Results suggested that the impact of an indicator on expert judgment of threat tends to decrease over time and that increments in threat value when indicators are aggregated are not simply a linear combination of the individual threat values. Broader implications of this dynamic nature of insider ...
The complexities surrounding insider threats often lie in their deceptive simplicity. At first glance, the activities of an insider threat might appear no different from everyday operations, which is precisely what makes them so elusive and dangerous. Here’s a closer look at why these threats are...

evaluate a breach or security event. However, unlike IOCs, IOAs are active in nature and focus on identifying a cyber attack that is in process. They also explore the identity and motivation of the threat actor, whereas an IOC only helps the organization understand the events that took place...
An indicator of compromise (IOC) is a piece ofdigital forensicevidence that points to the likelybreachof a network or endpoint system. The breach might be the result of malware, compromised credentials, insider threats or other malicious behavior. By the time a security team discovers an IOC, ...
For example, a sudden spike in data transfers or communication with a known malicious IP address can indicate an attacker attempted to steal data. Privileged account irregularities Unexpected use of privileged accounts can signal an insider threat or a compromised account. Administrators changing user-...
Unusual activity is flagged as an IOC which can indicate a potential or an in-progress threat. Unfortunately, these red flags aren’t always easy and obvious to detect. Some of these IOCs can be as small and as simple as manipulating metadata elements. Or they can be incredibly complex mal...
Indicators of Attack Indicators of attack are similar to IOCs, but rather than focusing on forensic analysis of a compromise that has already taken place, indicators of attack focus on identifying attacker activity while an attack is in process. Indicators of compromise help answer the question “...
Company decision makers need to broaden their damage estimating models and consider “peanut butter spreading” of security spending to account for post-breach expenses. Insidious insider attacks. Network breaches that escalate due to an intruder leveraging a privileged account remain all too common. ...
