Over the last 3 months I have been devoting a large number of hours towards the art of Penetration Testing (Pen Testing). I thought I would write a post about this subject to explain what it is. It is one of the new services I offer my clients.

A penetration test is the process of actively evaluating your information security measures by simulating an attack from a malicious source.

Data Systems, applications, websites and any other software can be tested remotely. Physical security, wireless networks and personnel security audits are normally conducted on-site.

I was recently asked by a solicitor to examine images to determine if they have been digitally manipulated. There are a number of processes I use including Photoshop forensic techniques and Error Level Analysis.

Error level analysis can help you work out if a photo has been digitally altered. Photos in a jpeg file format actually lose quality each time they are re-saved. I can take advantage of this to try and work out if an image has been digitally manipulated.

Just to follow up on my post “HOW TO AVOID BEING FOOLED BY SOCIAL ENGINEERING TECHNIQUES”

1. That old saying, how does it go? “If something is too good to be true, it probably is”.

2. A important question to ask yourself would be , “Why am I being singled out for special treatment or a winnings from millions of other people on the internet” If you cant find the answer, it probaby is a scam.

3. Please dont believe all that you read, scammers will present you with attractive websites, but that does not indicate that it is being truthful.
