Are you worried about Microsoft Exchange security

Your company's email is bombarded on daily basis with emails containing spam, viruses, spyware, malware and rootkits. There are many infamous examples of companies, who's intranets were invaded by trojans contracted from viruses attached to email. You should read up on how to manage security within Exchange server, so that you can take the edge off and sanitize the incoming emails

Some pointers when searching for exchange functionality with regards to securing your email:

• Spam blocking and filtering - when you filter and block spam messages, your system will require less storage, your employees will spend less time deleting emails and you minimize chances of an employee unleashing virus arriving in spam message
• Integration of virus scanning software - this will allow you to block viruses even if they come from normally trusted sources. Once a computer is infected, it may send emails on behalf of the owner without the owner knowing about it. Blindly trusting files coming from boss, for example, is not a good idea
• Set up digital signatures and encryption to both protect the message as well as protect the message content from being modified in transit. If your email contains digital signature, attaching a virus during transport will yield verification errors. With encryption, you will protect content of the message from prying eyes.
• Block files by extension - some default extensions that would get executed on client include EXE COM PIF BAT and many more. By blocking all files with these extensions you will minimize the chances of virus being executed on employee's computer
