THE HIDDEN COSTS OF FALSE POSITIVES IN ENDPOINT DETECTION AND RESPONSE
HANDLING A
FALSE POSITIVE
AND IMPROVING
MITIGATION
TECHNIQUES
It’s crucial to e昀케ciently handle
false positives to maintain
optimal security operations and
customer trust. Here are our
recommendations for e昀昀ectively
managing false positives:
Thoroughly Verify the Alert
Con昀椀rm the validity of any alerts
by cross-referencing them with
other security logs and threat
intelligence. An alert should
be documented and classi昀椀ed
accordingly if it is deemed a
false positive.
Examine Detection Rules
and Context
Document and Report
Findings
Review the context and settings
that led to the false positive. This
includes analysing detection rules,
tool con昀椀gurations, and network
tra昀케c patterns. Understanding the
root cause helps re昀椀ne systems
and reduce the likelihood of similar
false positives in the future.
It is essential to keep detailed
records of false positives, including
the nature of the alert, the
investigation process, and the
resolution. Proper documentation
aids in reporting and serves as
a reference for improving
security measures.
Adjust and Optimise
Detection Parameters
Communicate with
Stakeholders
Update your detection rules
and thresholds to minimise
false positives. This may involve
updating signatures, modifying
sensitivity levels, or re昀椀ning
anomaly detection settings to
match the organisation’s speci昀椀c
environment better.
Inform relevant stakeholders
about false positives and their
potential impact. Transparent
communication helps manage
expectations and maintains trust
within the organisation.
Continuous Improvement
Use false positive incidents as
opportunities to review and
enhance incident response
processes. Regular software
updates and training should be
implemented to handle similar
situations better and improve
overall security operations.
