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.

Phishers send well crafted emails as if coming from a valid source like your bank tricking you to enter your bank account or any portal (like eBay or Paypal) details including login and password or PIN numbers . Once, you enter the details, they are sent to remote servers. Now, that’s more than anything for the hackers to loot money out of your account.
Taking security seriously, we will discuss the community aided Netcraft tool bar for Internet Explorer & Firefox. First of all, I have to applaud NetCraft toolbar as by far the best toolbar that you can get for free. When I tested a new eBay scam email URL, no other toolbar other than NetCraft can catch the Phishing URL.

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.
