Hi,<br />
<br />
Can anyone please advise if it is possilble to modify/restrict the advertised SSH version information when connecting to an ASA 5505 (with an IPS module). &nbsp;The purpose of this is to prevent a potential attacker taking advantage of identifying the version of SSH and then launcing a targeted exploit.<br />
The ASA does restrict the source IP range of where SSH connections can originate from. <br />
<br />
The ASA is running version 8.4 code.<br />
<br />
Cheers,<br />
<br />
Phil

Prevent ASA 5505 SSH server from revealing version number

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals.
