E-mail (electronic mail) is possibly the greatest invention of online communication. It is an easy, quick and relatively low cost communication way for both personal and business usage. With expanding number of global Internet user and technology enhancement, email has emerged as the main medium for information exchange and document delivery.
With billions of email transaction daily, it has created a pathway for the cyber criminals to deliver malware into targeted network system. Malware is one of the most menacing software and it is designed to damage a computer system and open pathway for unauthorized access to the computer’s data storage.
Although, many organizations have installed firewall system to prevent intrusion and unauthorized access to its network, however every security system has its own loophole, so does the firewall system. Firewall may be effective to filter malware-attached-emails from unauthorized users, yet it is defenseless to sort out threats from authorized senders. Firewall does not look into the content of authorized user’s emails; therefore malware are able to enter an organization’s network via emails from business partners, product or information enquirer, employees’ personal email and many more.

Obviously, firewall system is not able to stop cyber criminals from breaching into an organization security system completely. Though it is important to constantly update the organization’s security software and hardware tools, consistent training to the IT workforce must not be overlooked. An excellent IT security infrastructure combines the finest and up-to-date security software and hardware with a well trained IT workforce.
