Meet the Anti-Nmap: PSAD - Having a great defense involves proper detection and recognition of an attack. In our security world we have great IDS tools to properly recognize when we are being attacked as well as firewalls to prevent such attacks from happening. However, certain attacks are not blindly thrown at you - a good attacker knows that a certain amount of reconnaissance and knowledge about your defenses greatly increases the chances of a successful attack. How would you know if someone is scanning your defenses? Is there any way to properly respond to such scans? You bet there is...

Understand: Fork Bombing Attack - As the variety of attacks and threats grow, you need to be prepared. In this HOWTO, get a feeling for the Fork Bombing Attack, what it is, how it works, where it comes from, how to deal with it and more.

  Will Mozilla's $3,000 bug bounty make Firefox secure? (Jul 19)
 

Mozilla is increasing the amount it pays security researchers for bugs from $500 up to $3,000. I personally think that's a very good thing.There has long been a debate about whether or not vendors should pay for security flaws. In my view, the flaws are going to be discovered whether or not a vendor is paying for them. The question is how they will be disclosed and whether or not those flaws will end up putting millions of users at risk - or not.By paying for flaws, what Mozilla is doing is providing an economic model for both security researchers and for itself. For security researchers, a $3,000 payment is not an unreasonable sum in my view and it's more than the $1,337 that Google pays. HP's TippingPoint also pays for security flaws as well though they seem to have a floating scale on payments as far as I can tell.

  A Brief History of Encryption (Jul 19)
 

Nearly nine years after the publication of FIPS 197, AES encryption remains the de facto standard today for symmetric encryption, and brute-force attacks remain infeasible, at least for the foreseeable future. To date, most attacks methods have focused on weaknesses or characteristics in specific implementations, called "side-channel attacks," not on the algorithm itself.

Mozilla on Thursday boosted bug bounty payments six-fold by increasing the standard cash award to $3,000.The new bounty for vulnerabilities in Firefox, Firefox Mobile and Thunderbird is also six times the normal payment by Google for flaws in its Chrome browser, and more than double the maximum $1,337 that Google pays for the most severe bugs.

  Dell offering free Web browser security tool (Jul 19)
