Intrusion Prevention
Performance
Because every packet is checked against every signature in the signature file
and each protocol anomaly threat, performance can be impacted. However,
you can enhance performance by disabling signatures that you do not need.
For example, if MS SQL is not used in your network, you can disable all MS
SQL-related signatures. Use the IPS Signatures Wizard to enable or disable
specific signatures in the signature file.
