Malware

Malware is malicious software designed to damage, disrupt, or gain unauthorized access to computers and networks.

Mean Time to Contain (MTTC) in Cybersecurity

Mean Time to Contain (MTTC) measures how quickly a security team can stop a threat from spreading after it’s detected.

Mean Time to Respond (MTTR)

Slow MTTR isn’t just a technical problem—it’s the result of alert overload, manual processes, fragmented tools, and missing context that delay response and increase business risk.

MTBF (Mean Time Between Failures)

MTBF measures how long a system typically runs before it fails, helping teams track reliability and reduce unexpected downtime.

MTTD (Mean Time to Detect)

MTTD measures how long it takes to detect a security incident after it begins, revealing how quickly an organization can spot threats before they escalate.
