Mail and messaging infrastructures have become crucial components of today's organizations. To protect mail and messaging infrastructures organizations must establish mail and messaging management solutions. This eBook introduces three fundamental mail and messaging management services - security, availability and control services - and how you can implement them in a Microsoft-centric mail and messaging environment using Symantec and Microsoft solutions. This eBook will prove that securing a mail and messaging infrastructure is not an afterthought. A secure mail and messaging infrastructure is fundamental to your business and any organization should plan for the appropriate message hygiene, availability, and control services from the start.
Email and messaging infrastructures have become crucial components of today's organizations. They provide email itself, instant messaging, collaboration, and unified messaging tools to an organization's users. Email and messaging systems are so essential that if they go down, your business stops.
Protecting your email and messaging infrastructures is the primary goal of email and messaging management solutions. Email and messaging management solutions provide services in three key areas -- security, availability, and control.
- Security services keep harmful content out and important content in. These services are also referred to as message hygiene services. Security services ensure that malicious content -- such as spam, viruses, and malicious software (malware) -- is blocked from interfering with and doing harm to your email and messaging infrastructures. Security services also filter outgoing email and messaging content to ensure that confidential company data stays inside your organization.
- Availability services keep your email and messaging systems up and the costs of those systems down. Availability services include continuous data protection services that guarantee that authorized users can access information when they need it and disaster recovery services to ensure that the information contained in your email and messaging infrastructures can be rapidly and easily recovered.
- Control services keep your email and messaging infrastructures under control, by centralizing remote Personal Folders (PST files) to ensure protection, archiving messaging data to manage storage space, and indexing information to allow for quick discovery of information. They also perform journaling services to help your organization conform to regulatory and legal requirements and include encryption services to ensure the integrity and confidentiality of the information stored in your email and messaging infrastructures.
Chapter 1 introduces the three email and messaging management services outlined above. In this chapter, I'll first provide the business case for protecting your email and messaging infrastructures. I'll then present an overview of the IT threat and security landscape and show how this landscape affects the solutions you can consider to provide adequate security, availability, and control services.
