Recovering data and investigating scams and hacking are serious and intricate jobs. Governments all over the world, multimillion dollar credit cards companies hired digital forensics experts to look into cyber crimes. Here are just 10 techniques many forensics use.
1. Image Back-Up:
A detailed copy of files on the computer`s hard drive is done and used to examine the data to prevent damage to the original drive. The backup takes deleted and current files on the drive.
2. Packet Sniffing:
This involves sensing things, seeing if the data sensed has any meaning. Data includes user names and passwords, sent and received email and any data that is received that comes through networks.
3. IP Address Tracing:
Every computer network is hooked up to an IP Address. This address is what computers use to identify each other. Tracing IP Addresses track the person to the exact address in real life. IP Address tracing may include reverse address look up.
4. Email Address Tracing:
Every email that is sent through an IP Address. IP Addresses are always connected to some kind of address in the real world. You can do this by looking through the header of each email.
Sometimes information is hidden in images, sounds and other files that are hard to catch. Decryption and stag-analysis are needed to obtain the info from the files.

1. Reduce costs
First of all, it relates to goods that are not included in the list of basic life necessities. Keep records of what you buy, where and how much you pay for those goods. Review the list of purchases at the end of each month and cross out unnecessary items.
2. Save money
Start to save money for unforeseen expenses. Analysts recommend to save around 10% of monthly income. Make sure that you automatically deduct the amount from your salary to avoid temptation of spending it. Postpone a small amount for entertainment – the nerve cells do not recover.
3. Look at all the services you use
Perhaps you do not really need the rate of cellular communications, with the possibility of sending an unlimited number of text messages, unlimited internet bandwidth, which can be used only for limited purposes and so on. In any case, surely there are services for which you pay, but not fully use.
4. No debt
Under no circumstances go in debt. Use credit only as THE last resort. Think before you make a step towards the debt.
5. Think about the future
Despite all the financial problems, do not forget to put off money for retirement. Think about your future and the future of your family.
