1. INTRODUCTION

In recent years, countries around the world have been developing rules and regulations which are designed to support data confidentiality and security. Many organizations have spent decades on building stronger defenses against intrusion, including firewalls, anti-virus software, email security, identity access badges, security policies and procedures. These protections have made the business world more effective at blocking threats and attacks from the outside and made it increasingly difficult for hackers and viruses to penetrate into the system. However these protections provide only a first line of defense since it is designed to prevent unauthorized access.

There are also threats and attacks from the inside of the organizations and sometimes these can cause far more damage to the organizations than external attacks. Also it is considered the most difficult problem to detect and deal with because an insider is a trusted member of the organization and has access to information, valid authorization and capabilities [8]. Therefore the discussion of insider threat is important and must be well defined in order to analyze the problem precisely and approach a solution.

    However, too many organizations fail to identify the potential threats from information unintentionally leaked, freely available over the Internet, and not normally identifiable from standard log file analysis. Most critically, an attacker can passively gather this information without ever coming into direct contact with the organizations servers – thus being essentially undetectable. Very little information has been publicly discussed about arguably one of the least understood, and most significant stages of penetration testing – the process of Passive Information Gathering. This technical paper and information gathering plan reviews the processes and techniques related to the discovery of leaked information. It also includes details on both the significance of the leaked information, and steps organizations should take to halt or limit their exposure to this threat.…
