Oracle 10g Improved Network Outage Detection
sqlnet.inbound_connect_timeout – This
parameter is used to limit the time, set in seconds, for a client to
connect with the database server and provide the required
As we have all seen with recent worm and virus
attacks, unauthorized access to a system service such as the
Listener or database server can result in denial-of-service attacks.
In a denial-of-service attack, an unauthorized client attempts to
block the authorized users’ ability to access the system. Malicious
clients or hackers may attempt to flood the Listener or database
server with bogus connect requests solely to consume resources, such
as connections, processes, or threads.
To minimize the effect of denial-of-service
attacks, you should configure limits that constrain the time in
which resources can be held prior to authentication. In this way,
client attempts to exceed the configured limits will result in
connection terminations and an audit trail containing the IP address
of the client being logged.
To limit consumption of Oracle 10g’s resources
by unauthorized users and enable an audit trail, you should set
time-limit values for the sqlnet.inbound_connect_timeout parameter
described previously. (This parameter does not have default values.)
