Understanding Your Data
Threat Types Explained:
IP Addresses: Malicious servers or computers on the internet
Domains: Suspicious websites that might host malware or phishing pages
URLs: Specific web pages that are known to be dangerous
Hashes: Digital fingerprints of malicious files
Emails: Phishing email addresses or malicious sender addresses
Threat Levels:
High: Immediate threat that requires attention
Medium: Potential threat that should be monitored
Low: Suspicious activity that might be worth investigating
How Threat Level is Calculated
The "Threat Level" (High, Medium, Low) helps you quickly understand how dangerous a threat might be. The application calculates this automatically for each threat using a combination of simple rules:
Source Reputation: If the threat comes from a highly trusted source (like a well-known security feed), it is considered more serious.
Confidence Score: Each threat has a confidence score (0–100) that shows how sure we are that it's real. Higher confidence means a higher threat level.
Recency: Newer threats are considered more dangerous, because attackers often use new tricks to avoid detection.
Type of Threat: Some types of threats (like malware or phishing) are more dangerous by nature, so they may be rated higher.
In simple terms:
If a threat is new, comes from a trusted source, and has a high confidence score, it will be marked as High.
If it's older, or the confidence is not as strong, it may be Medium.
If it's just a little suspicious or comes from a less reliable source, it will be Low.
You don't need to do anything—this is all automatic! The goal is to help you focus on the most important threats first.
Where Does the Confidence Score Come From?
The confidence score is a number (from 0 to 100) that shows how certain the system or the original data source is that a particular threat is real and not a false alarm.
From the Feed: Most threat intelligence feeds (like AlienVault OTX, Abuse.ch, etc.) include a confidence score for each threat. This score is provided by experts or automated systems running those feeds, based on their own analysis and criteria.
For example, a feed might say: "We are 95% sure this IP address is malicious," so the confidence score is 95.
If Not Provided: If a feed does not provide a confidence score, the application assigns a sensible default (for example, 50 or 60), or estimates a score based on other available information (such as the reputation of the source, how recent the threat is, or the type of threat).
Manual or Custom Feeds: If you add a custom feed or enter data manually, and there's no confidence score, the app will use its default or estimation method.
In summary:
Most of the time, the confidence score comes directly from the threat feed itself.
If not, the app uses a sensible default or makes an educated guess.
Confidence Scores:
90-100: Very reliable threat information
70-89: Reliable information from trusted sources
50-69: Moderate confidence, may need verification
Below 50: Low confidence, should be investigated further
