The problem is Sony has waited 2 weeks to tell us before that they've been hacked. This time they tell us they know it's down, but don't even bother to say "we are experiencing technical difficulties" when they have got to know what's on everybody's mind. It's one thing to understand the technicalities, and it's another thing to defend their terrible PR.
Sigh, i can go pages on pages on the process that is needed to start an investigation, analyze the breach, investigate what was looked at or taken , and the fix for the network, but i don't have the time to do that today. If you really want to know, I can write one up in a couple of days on my day off work. But what I can do for you is say this:
The fact that Sony was able to get the customers information in 2 weeks is amazing. The amount of time/ money / manpower needed to pull that off is really amazing over all. When the IDS (intrusion detection system) goes off for my company, for any of our customers, the RCA (root cause analysis ) can take up to a couple months depending on the level of the breach. Oh and one thing, if they use an IDS, only if the attack happened from a non-trusted source would cause the alert. This means that when Sony was breached; it came from a trusted connection. Now, how would that be possible? I will bet a good amount of cash that it was from the information on hacked ps3 which was able to gain trusted access to the network. So this means that the “hackers” can by pass the security measures in place which would stop normal attacks because the connection to the network at the time was trusted. So that "un-patched" server is now vulnerable to attacks. But Sony will never admit to it. If they did, then they would just be setting the company up for a complete down fall.
The only major fault to Sony is that they used the same private/public keys on different layers of security, when it should have been different on each layer on the PS3. This is the real cause of the PSN hack. The "un-patched" server theory is just laughable.
This is why i keep saying that people really need to think about the size of the network Sony, Microsoft, and other major companies use.
