Best Practices for Secure Email Policy and Compliance
Whether you are complying with government regulations or protecting against intellectual property leaks, all organizations need an email policy in place.
Fight Image Spam
with Your Eyes Open
Businesses and security experts alike have noticed image spam's role in the recent explosion of worldwide spam. Like any new technology that spammers use, it is meant to get around existing antispam technologies. Some vendors develop advanced, cutting-edge tools to fight new attacks today-AIF (Adaptive Image Filtering) is one example of this. Any vendor that claims to stop image spam without actually looking at the image is misleading their audience. Keeping your eyes open-that is, using advanced tools that thoroughly analyze images-is the most effective method in fighting image-based spam.
Best Practices for Inbound Email Security
Email is everywhere, used by everyone and for everything, and because of this many marketers use it to convince readers to buy their products. Attackers also use email to trick readers into either revealing personal or financial information or running malicious code on their machines. These dangers mean that organisations' email policies have become increasingly complex, and that email security is now the first line of defence from malicious attacks. This paper will discuss best practices for this first line of defence, including security approaches, types of filtering, and other security measures related to email.
Guide to Evaluating Next-Generation Email Security Technologies
Choosing the right email solution may not change the way businesses communicate, it will deliver dramatic savings-not just in the areas of budget and infrastructure, but also in the time and resources of IT professionals and their organizations. This booklet provides a framework for evaluating next-generation email security solutions while addressing a number of specific issues including: Creating a secure email architecture and infrastructure; combating the latest inbound threats; policy-driven control and content filtering; best practices for securing outbound messages; and integration and consolidated management.
Secure Email Inside the Corporate Network
Each organization has its own unique security needs when it comes to sending and receiving sensitive information via
email— from complying with government privacy regulations in Healthcare (HIPAA) and Financial Services (GLBA)
to enforcing corporate policies (SOX) and protecting intellectual property. Although individual implementations
vary, current email security requirements typically fall into two categories: inbound email protection and outbound
email security.
Understanding Proactive vs. Reactive Methods for Fighting Spam
To date, spam filtering techniques have fallen into several categories: blacklists, rules and heuristics, or more
recently, Bayesian filters and signature technologies. However, none of these existing reactive approaches, have
done an adequate job of solving the spam problem. These existing techniques result in a constant battle of
misclassification – either in the form of a legitimate message being mistaken for spam (false positive) or a
spam message being mistaken as legitimate (false negative).
Email Content Filtering Strategies for GLBA Compliance
In the financial industry, email plays an important role in the efficient day-to-day execution of business. It's
critical that financial institutions can ensure the privacy and protection of personally identifiable financial
information and Title V of the Gramm-Leach-Bliley Act (GLBA) sets those standards. Consequently email management
systems must provide tools and techniques that enable companies to comply with the GLBA.
