The document discusses the key features of an effective email security solution. It outlines eight important features: password policies, content filtering, reporting and log search, administrator management, user management, data classification, data-centric security, and unauthorized recipient check. Each feature is then discussed in more detail across multiple paragraphs. The conclusion states that while the outlined features are important, additional capabilities like anti-spam, anti-virus, outbound filtering, and email archiving further improve email security.

Top 8 Features of an Effective
Email Security Solution

OVERVIEW
An email security solution protects the emails in at least one of the ways
mentioned above. However, with the increasing demand for a higher
level of security, the list of desired features for an effective security
solution keeps growing.
There are three ways of protecting an email:
● Stopping the emails at the origin by deploying Data Loss
Prevention (DLP) solutions and Secure Email Gateways (SEGs)
● Encrypting the emails in transit to avoid eavesdropping
● Securing the emails even after being delivered to the recipient,
that is, while data is in use.

PASSWORD
• The password is of paramount importance for email security.
• Weaker passwords can cause loss of both data and reputation for the
organizations.
• Additionally, password policies are a complex web of rules and
regulations.

Seclore suggests the following tips while setting password policies:
● Use strong passwords: Passwords consisting of complex
combinations of uppercase and lowercase letters, special
characters, and numerals tend to work as solid passwords
● Never reuse passwords
● Mandate two-factor authentication for employees
● Block access on multiple unauthorized attempts

Content filtering deals with government compliance and protection against
the misuse of corporate emails.
Many Digital Rights Management (DRM) solutions provide data-centric
security around emails. But standalone systems cannot offer wholly secure
and usable systems to protect outbound information.
Make sure the system you are evaluating has the following:
● Mechanism to define custom filters based on organizations and
geolocation
● Predefined filters for standard data types
● Filter both inbound and outbound emails
● Filter based on DomainKeys Identified Mail (DKIM) signature

While email security is one big area, it becomes the elephant in the room
without efficient incident reporting.
So, while having a robust email security system is good, it is even more
essential for the solution to support incident management and efficient
log searching.
Make sure the system you are evaluating has the following:
● Separate reports for admins and users.
● Configurable frequency of reports.
● Allow flexibility to generate reports as and when users request
manually.
● Detailed log search, i.e., based on IP, countries, senders, recipients,
and many more.
● Search based on attachment content of standard file format

LOG SEARCH

The administrator management console of the solution should be simple
and provide as much flexibility to end-users.
It should allow administrators to do the following tasks:
● Create global and domain-level policies
● Allow searching end user’s quarantine or global quarantine.
● Granular usage control
● Activity audit of administrators
● Multiple domains
● Integration with the identity management system of the enterprise

Security is not an IT admin-only job anymore.
We need to involve users where they can actively participate. When it
comes to email, it directly impacts end users with efficiency.
An efficient email security solution should have the following features:
● User and admin console
● Ability to set up spam, quarantine, block listing rules
● Generation of reports to end-users and insight into their email
activities

The email security system should provide email classification based on
the content of the mail. Alternatively, the solutions should have ways to
integrate with existing data classification solutions and have a mechanism
to write rules based on data classification.
Most of the email classification systems use classification for emails as x-
headers and attachments as custom properties. While classifying the data
might not be provided by email security systems, identifying the already
classified content is a must-have feature.
Make sure the system you are evaluating has the following properties:
● Capability to write rules based on x-headers
● Capacity to write rules based on custom properties of attachments
● Ability to route emails via classification systems

Though most of the above reasons help your post-facto analysis of the
emails, the proper security of the email can come only when the emails
remain always protected during the transmission and the usage of the data.
Data Rights Management (DRM) solutions provide data-centric security for
emails.

SECURITY

Wrong recipients are one of the reasons for data leakage because
users make mistakes while marking emails.
Modern email security systems are working hard to prevent emails
from being automatically sent to unauthorized users.
With machine learning & AI, it’s possible to identify whether an email
has reached an unintentional user.

CONCLUSION
Content filtering, reporting, and data classification are mandatory for any
email security solution. However, the following features improve the
functioning of an email security solution and add to its value on an enterprise
level:
● Anti-spam
● Anti-virus and anti-malware
● Outbound filtering
● Email spooling and continuity
● Email archiving
