Securing Your Email in 13 Steps: the Email Security Checklist Handbook Securing Your Email in 13 Steps
HANDBOOK Securing Your Email in 13 Steps: The Email Security Checklist handbook Securing Your Email in 13 Steps overview You’ve hardened your servers, locked down your website and are ready to take on the internet. But all your hard work was in vain, because someone fell for a phishing email and wired money to a scammer, while another user inadvertently downloaded and installed malware from an email link that opened a backdoor into the network. Email is as important as the website when it comes to security. As a channel for social engineering, malware delivery and resource exploitation, a combination of best practices and user education should be enacted to reduce the risk of an email-related compromise. By following this 13 step checklist, you can make your email configuration resilient to the most common attacks and make sure it stays that way. 2 @UpGuard | UpGuard.com handbook Securing Your Email in 13 Steps 1. Enable SPF How do you know if an email is really from who it says it’s from? There are a couple of ways to answer this question, and Sender Policy Framework (SPF) is one. SPF works by publishing a DNS record of which servers are allowed to send email from a specific domain. 1. An SPF enabled email server receives an email from [email protected] 2. The email server looks up example.com and reads the SPF TXT record in DNS. 3. If the originating server of the email matches one of the allowed servers in the SPF record, the message is accepted. -

Characters in the Local Part of a Mail Address RFC2821 and RFC2822 State Clearly That Only 7Bit ASCII Characters Are Allowed in Internet Mail Addresses
Characters in the local part of a mail address RFC2821 and RFC2822 state clearly that only 7bit ASCII characters are allowed in Internet mail addresses. The following list shows all the ASCII characters and explains whether they can or should be allowed in the local part of a mail address. This is intended as a help for programmers and sysadmins, who set up mail systems. Source: http://www.remote.org/jochen/mail/info/chars.html Dec Hex Char Usable? Description 0-31 0x00-0 Control NO Not allowed by RFC2822. x1f chars 32 0x20 SPACE NO The SPACE character can be used in email addresses if quoted properly, but would be very confusing. Don©t use it. 33 0x21 ! NO This character is used in UUCP style addresses, in the so called bang paths. Example: host2 ! host1 ! user. Because there are still lots of mail systems who interpret this chars specially it should never be used in the local part of an email address. 34 0x22 " NO The double quotes are used for quoting. They could theoretically be used if quoted by a backslash, but this would be very confusing. Don©t use them. 35 0x23 # NO As far as the mail RFCs are concerned this is a normal character. But the hash sign is used in many configuration files to denote the beginning of a comment. Used in the configuration of most MTAs it would probably not work. Don©t use it. 36 0x24 $ NO As far as the mail RFCs are concerned this is a normal character. Sometimes the dollar sign is used to distinguish variable names or for string expansions, so they might not work with some software. -
Idns: Internationalized Domain Names Did You Know?
I N T E R N E T C O R P O R AT I O N F O R A SS I G N E D N A M E S A N D N U M B E R S IDNs: Internationalized Domain Names Did you know? · Internationalized Domain Names (IDNs) are domain names with characters other than a, b…, z; 0, 1,…, 9; and “-“. · IDNs on the second and third levels exist in some generic top-level domains (gTLDs) and in some country code top-level domains (ccTLDs). TLD registries determine the choice of characters available under these TLDs. · Some languages, like Arabic, are written from right to left. IDNs at the second level are not very useful for the communities that use these languages because users would need to change both the type direction and script in the middle of entering a domain name. · IDN TLDs will be made available through two separate processes, initially through the New gTLD Program and the IDN ccTLD Fast Track Process. · 60 percent of Internet users are non-English speakers, while the dominant language used on the Internet is English (see Global Reach at www.glreach.com). One of the most significant innovations in the Internet since its incep- tion is the introduction of Internationalized Domain Names (IDNs) in the Internet’s address space. You may be familiar with some of the larger top- level domains: dot-com, dot-cn, and dot-org are just three examples. IDN top-level domain names will offer many new opportunities and benefits for Internet users around the world by allowing them to establish and use domains in their native languages and scripts. -
How to Add an Email Address to Your Safe Senders' List
How to Add an Email Address to your Safe Senders' List An increasing number of e-mail clients (Outlook, AOL, Hotmail, etc.) are including spam blockers that can affect delivery and display of some e-mail messages. This means that sometimes those desired e-mail communications might not reach you, or they might be displayed without images. To ensure that you continue receiving your e-mail or your subscriptions, and that they display properly, we recommend adding the email address or domain to your list of safe senders. Here are some instructions to help you do that: Instructions regarding email clients Apple Mail • Add the email address to your address book. • In Training mode, emails will arrive in the INBOX highlighted in brown. In Automatic mode, junk emails will arrive in the Junk box. To add an email that arrived in the JUNK folder, highlight the email message. • Choose Message > Mark > As Not Junk Mail AOL For AOL version 9.0: You can ensure that valued e-mail is delivered to your Inbox by adding the sending address to your "People I Know" list. • Open your latest issue of Brill’s E-Newsletter. • Click the Add Address button (over on the right) to add that sender to your "People IKnow" list. Alternatively, you can simply send an e-mail to [email protected]. Even if the e-mail you send doesn't get through (for whatever reason), the act of sending it does the job of putting the address into your "People I Know" list--and that's what counts. -

M3AAWG Best Practices for Unicode Abuse Prevention February 2016
Messaging, Malware and Mobile Anti-Abuse Working Group M3AAWG Best Practices for Unicode Abuse Prevention February 2016 Executive Summary For years, visually confusable Unicode characters – e.g., using the Greek omicron (‘ο’ U+03BF) in place of a Latin ‘o’ – have provided the potential to mislead users. Because most functional elements, like links and addresses, were previously limited to ASCII, abuse remained peripheral. However, the scope and definition of this abuse are poised to change with the advent of International Domain Names (IDNs), Internationalized Top-Level Domains (TLDs), and Email Address Internationalization as these non-ASCII and non-Latin characters gain in popularity. This document outlines M3AAWG best practices to curtail the Unicode abuse potential of such spoofing, while supporting the legitimate use cases. The intended audiences for these practices are: email service providers, Internet service providers, and the operators of Software as a Service or others in relations to other Internet-connected applications. A brief tutorial explaining how Unicode characters are used to perpetuate abuse can be found in M3AAWG Unicode Abuse Overview and Tutorial paper. This paper can be downloaded from the Best Practices section of the M3AAWG website. I. Background The M3AAWG best practices approach is to disallow certain characters not in common usage, as well as the combining of confusable scripts within a single label, with exceptions made only for certain visually distinct combinations found in legitimate usage. The intent of this exacting strategy is to inhibit suspicious combinations from taking hold by legitimate users, while ensuring a clean delineation of what constitutes abuse. For consistency and defensibility, these strategies are based on the Unicode Consortium’s standardized “Restriction Levels” definition1, which takes into account expected legitimate combinations of character sets. -
