Email Encryption For Added Security

If you find yourself wondering how to open encrypted email in Gmail, adding an extension is your best option. These are the steps youll need to follow:

What About Gmail Confidential Mode
The term confidential mode is a bit misleading from an encryption standpoint. What the confidential mode does is it allows you to have more granular control over emails you send. With Gmail confidential mode, you can do the following:
- Set an email to expire. You can opt to set an expiration date for an email. This provides an artificial deadline for the email you send.
- Remove access. If you no longer want someone to have access to an email, you can choose to remove their access to an email sent in Confidential Mode.
- Require a passcode. You can choose to have Google generate a passcode for the recipient, which will then require them to use that passcode to open the email you send them.
This has several issues. First, generating a passcode requires you to give Google the recipients phone number. Second, confidential mode is not encryption. Unless both parties use TLS for email, Google will still be able to read an email sent in confidential mode so long as its in your sent folder, even after an expiration date passes.
We will stop short of calling Gmails confidential mode unsafe. It has features that provide a level of assurance the right people read your emails in an appropriate time, but this is not encryption by any standard.

No Saving Downloading Printing Or Copying
When you send a confidential email, the recipient will not be able to save, download, print, or even copy any of the content. This is also true for attachments: they are, in Confidential Mode, Read Only.
If you need the person receiving the email to do anything other than simply read and reply, Confidential Mode might not be the best choice. In those cases, its usually better to password-protect a document on your computer or share it through Google Drive.

Gmail Encryption: A Next
Beyond that basic form of encryption, Gmail supports an enhanced standard known as S/MIME or Secure/Multipurpose Internet Mail Extensions . It’s available , so if you’re using a regular free Gmail account, it doesn’t apply to you.
For folks with enterprise-level Workspace setups, though, S/MIME allows emails to be encrypted with user-specific keys so that they remain protected during delivery and can be decrypted only by the intended recipient.
Like TLS, S/MIME works only if both the sender and recipient are using a service that supports it and, in an extra layer of complication, only if both parties have exchanged keys in advance so that the encryption can be properly configured. Like TLS, it also doesn’t do anything to keep a message secured once it’s reached its actual destination server .
Last but not least, S/MIME has to be enabled by a Workspace admin before it’ll work.

Recognize And Avoid Phishing Attempts
According to KnowBe4, more than 90% of successful hacks and data breaches start from phishing scams. Phishing is the practice of sending fraudulent emails to individuals in a ploy to get them to send sensitive information to hackers.
Phishing emails used to be a little easier to notice, with misspelled words, sketchy-looking domain names, and grammatical errors. Unfortunately, social engineering has made phishing attacks look far more realistic.
Dont want to fall prey to a phishing attack? Whenever you are sent an email that requests your information, dont click any links in the email itself. Instead, navigate to that companys website and directly log in to your account there.
KnowBe4s Data Driven Defense Evangelist, Roger Grimes, notes that social engineering and phishing tactics are becoming increasingly sophisticated. Years ago, when you got a phishing email, it would have all kinds of typos in it, and it would be from some weird-looking email address, Grimes said. Youre like, Theres no way this is my boss, or, Theres no way this is Microsoft. But, these days, theyre a lot more sophisticated. Theyre more and more often actually targeting particular industries. Phishing attacks are starting to use industry-specific terms, jargon, and client scenarios to foster a false sense of trust. As they learn, hacking groups can make these emails look increasingly realistic.
Why Is Email Encryption Important
Email encryption is important because it protects you from a data breach. If the hacker cant read your message because its encrypted, they cant do anything with the information. Since 2013, over 13 billion data records have been lost or stolen. The average cost of a data breach in 2018 is $3.86 million. This number has grown by 6.4% since 2017. Data breaches can be costly because they take a while to identify. In 2018, the mean time to identify a breach was 197 days and the mean time to contain it was 69 days. Email encryption is a preventative measure you can take to avoid being part of a cybersecurity statistic.

How To Encrypt Email In Outlook
Just like Gmail, Outlook.com uses TLS encryption to protect the connection with a recipient’s mail service provider. The problem with TLS is that it protects messages only while they’re in transit and doesn’t guarantee that they’ll stay encrypted after they reach the recipient’s service provider.
Microsoft implemented its own Outlook email encryption system, which ensures that your messages always remain encrypted and don’t leave Microsoft’s servers. Outlook email encryption is available to Office 365 Home or Office 365 Personal subscribers, and it could hardly be any easier to use.

The second way to encrypt your email is by applying PGP/MIME.
It is a relatively safer protocol as it relies on a decentralized system. Thus, it gives you the liberty to choose your own encryption key.
Plus, you will find this quite affordable as you do not have to subscribe to any service.
Or, even if you use a paid service, it doesnt blow your budget.
The only problem with PGP is that you have to rely on third-party services to implement encryption.
However, this single limitation isnt a big deal given the freedom and the range of choice for implementing encryption.
Can I Encrypt An Email In Gmail
Google protects your messages through Gmail encryption. The Transport Layer Security encrypts the messages you send on Gmail and protects them from other eyes.
You can recognize it when you access your mailbox, as it shows on the URL box as a small lock icon.
Its an effective way to encrypt messages but not sufficient to provide enough security. For example, if youre sending an email and anti-virus with message-checking services, it offers a loophole for an attack.
The message is safe while on transit but can be easily accessed from the receivers inbox, as the message itself is not encrypted.
TLS protects only the channel of communication while the contents of the email remain unprotected. This makes it vulnerable to hackers and unwelcome Googles surveillance as they scam your emails for spam content and suspicious phishing attacks.
Considering TLSs inefficiencies and breach of privacy, Google introduced different services to help Gmail users send their messages confidently. You can use any of these three ways to encrypt your email in Gmail.

Using Certificates To Encrypt Emails
S/MIME encryption could be useful when both the sender and recipient have installed and shared the encryption certificates.
However, this encryption method isnt widely supported.
Its only available to an individual with an email account incorporated into Outlook. Even the intended recipient should be an Outlook user or use an email platform thats compatible with S/MIME.
Heres what you need to do to set up email encryption with S/MINE on Outlook:
Acquiring Email Encryption CertificateYou need to acquire an email encryption certificate for yourself, import it into Outlook, and then share it with the recipients.
Next, you have to verify that each intended recipient has purchased and installed an email encryption certificate into Outlook or other S/MIME compatible email platforms. This certificate must be shared with you as well.
Moreover, make sure you buy the email security certificate and not the SSL certificate.
Importing S/MIME Encryption Certificate Into OutlookStep #1 Open Microsoft Outlook. Select File on the top menu bar.

Step #5 Under the Digital IDs heading, click on Import/Export.
