Secure destruction of data like personal details, banking information, confidential company information or critical customer data when they are no longer required is very important to information security for the simple reason that they can always be recovered in many ways from the hard disk. This is even more important when you sell or throw away your old PCs. Simply deleting the files from the PC doesn't really remove the files for good. They can always be recovered. FileShredder just protects you from that. File Shredder is an opensource free file secure destruction software for permanent removal of critical confidential files from the hard disk. With File Shredder you can remove files from your hard drive without fear they could be recovered. File Shredder has been developed as fast, safe and reliable tool to shred company files.

Solaris Security – Disable ICMP Redirect in Sun Solaris
Solaris Operating Environment by default is configured to both accept and send the ICMP Redirect messages. According to RFCs, only a router or a gateway device should send an ICMP Redirect message and any other hosts should only be able to receive the ICMP Redirects. If the Solaris server is not acting as a Router or a Gateway then sending ICMP Redirect message should be disabled. The same applies to accepting ICMP Redirect messages if the solaris server is not required to receive ICMP Redirect messages (say a single Router/Gateway network/subnets scenario) as a malicous hacker could send fake ICMP redirect messages to modify the routing table on the host and potentialy cause a Denial of Service attack.
