Protection Needed for Email Client Security

Email security is a growing concern among organizations due to the popularity of this type of application for communications. Many companies and organizations are taking extra measures for securing email to ensure the integrity and confidentiality of email messaging. Additionally, email security is important from the standpoint of protecting the system against malware attacks, minimizing the receiving of spam, and ensuring that that the end users do not accidentally expose confidential and sensitive information.

If you are planning an email security system for your large business, small business, or organization, there are several components that you must include in the infrastructure to create the most secure environment possible for email communication.

Types of Email Protection

There are a lot of elements involved with email security and unless you can deploy a unified threat management system that does everything in one appliance, here are the elements that should be included in a solid email security system.

  • Reputable Antivirus Software: One of the most popular ways a virus or worm enters your email client is through an email attachment. This is why it is important to install a reputable antivirus program that provides the best protection possible against email viruses and worms. Preferably the program should scan all email attachments for viruses and worms.
  • Anti-Spyware: Hackers are notorious for sending Trojans, spyware, and adware through email attachments. Your email protection arsenal should include a good anti-spyware program that performs regular scans and provides updates on the latest types of malware.
  • Spam Killer: A good spam killer will help to cut back on the amount of spam that is received by your email client and helps to avoid the possibility of viruses entering your email through a spam message. A spam killer can also cut back on the number of phishing attacks that usually occur with spam messages.
  • Content Security Software: Most organizations deploy content security software to ensure that confidential and sensitive content is not revealed within the organization or sent outside of the organization either by accident or on purpose.
  • Encryption System: To ensure that email messages are securely sent and received, it is important to deploy a public key infrastructure that can be used to encrypt and decrypt email messages that contain sensitive information. A public key infrastructure is costly to maintain and usually used in large organizations. If you are a smaller organization, you may want to consider a web-hosted secure email solution.

  • Email Usage Policy: By implementing an email usage policy you cut back on the amount of email traffic that occurs as a result of personal use by the end user. An email usage policy will help to reduce company email misuse which provides added protection against unsolicited messages that occur as a result of using company email to sign up for services online or any other type of inappropriate use.
