Top Three Email Security Tips
http://epicecommercetools.com/2016/12/05/top-three-email-security-tips/ E-mail security is difficult. The primary problem is that even if you take precautions to protect your end of the conversation, you can do little to secure the servers and clients in between and on the receiving end. For this, you need to ensure that all the servers in question are being scanned for security vulnerabilities from someone like Trust Guard. Honestly, there’s no way to make sure that is happening, as it requires access to everyone who visits your email profile. Some services like Gmail offer enabled-by-default encryption between your computer and their servers, but sending a message from one server to another is still often unencrypted. You should definitely do what you can to secure your e-mail from casual snooping: 1. Use an account from a major provider like Google, Microsoft, or Yahoo. Do they get hacked? Yes. Are they safer than most? Yes. 2. Use a strong password and two-factor authentication enabled. If your phone uses a fingerprint reader, take advantage of that added convenience by locking your phone with a strong alphanumeric password. Target a 12- to 14-character minimum, since shorter passwords are more susceptible to brute force attacks – the longer and more random the better. Two-step authentication (or 2FA) means using a combination of multiple credentials to get into your account, usually a password and a six-digit code sent to your phone or generated by an authenticator app. 3. For truly sensitive communications that you want to keep private, use Signal or WhatsApp or even Facebook Messenger’s “Secret Conversations” feature. Delete old e-mails. Another mitigating factor for the e-mail problem is message retention—someone with ten years’ worth of data to dig through is naturally going to reveal more about themselves than someone who only has six months of messages. Even free e-mail providers often give you so much storage space that it can be tempting to be a digital packrat and just keep everything, both for nostalgic reasons and just in case you ever need it for something. But the more communications you store, the more information that companies, law enforcement, and, most importantly, hackers have to track your wheelings and dealings. Consider how important or sensitive your communications are, and consider how often you actually need old e-mails. Consider deleting e-mails at regular intervals—deleting things after one year or even six months can be a good way to start if this is something you’re worried about, and think about deleting unimportant messages even more frequently. Encrypt your phones and computers that you use to access your email accounts. Think of encryption as a massively complex decoder ring. When data is encrypted, it can only be accessed and read by a person or device that has the “key” needed to translate it back into its original form. It’s important to encrypt your communications, and it’s also important to encrypt the devices you use to access any sensitive data since that data can be stored on them locally whether you realize it or not. If the phone isn’t encrypted, it’s fairly easy to turn it on in the Securitysettings; protect the phone with a strong passcode afterward. There are several ways to keep your emails protected from hackers. But nothing, it seems, is fool-proof for hackers that really, really want to access your email account. Still, it’s still worth it to use these strategies to make your personal and business information as secure as possible.

Ladar Levison built an encrypted email service called Lavabit that counted a prominent figure among its users: Edward Snowden. After spending 10 years building Lavabit, he has to destroy it all in one night. When the FBI demanded Levison decrypt Snowden’s communications, he had two options, either hand over the encryption key or destroy his servers. He chose the latter. Now, he’s back and building an even more secure version of Lavabit that could make mass email surveillance obsolete.

End-to-end encryption protects your email messages from being stolen by hackers, read by spies, or used by Google or Microsoft for targeted advertising. Encrypted email is essential for protection of your online privacy, security, and digital rights. Mainstream email providers like Yahoo Mail, Gmail, or Hotmail, don't offer you end-to-end encryption because that would jeopardize their business model. However, your personal email should be completely private and not read by companies to make a profit off of you. Luckily, there are plenty of gmail/yahoo/hotmail alternatives that keep your messages private and secure from prying eyes of advertisers and governments. Don't expose your private email messages to hackers, cyber criminals, identity thieves, and governments around the world you can’t trust. Sign up with one of these secure and private email providers for an encrypted email. All of these private email services offer free basic entry for account creation, end-to-end encryption using asymmetric public key cryptography, public cause and activism, anonymous sign-up. What is end-to-end encryption, public key cryptography and asymmetric encryption? Asymmetric encryption is the one where users generate two keys to encrypt their data – a private key, and a public key. When someone wants to contact you securely, they use your public key to encrypt the message. To read the message when you receive it, you decrypt it with your private key. Since public keys are available to everyone, you need to make sure nobody tried to spoof your identity using your public key to impersonate you and communicate with your contacts. Tutanota.com encrypted email service review utanota is a free and open source email service based in Germany. The name stems from Latin and translates as “secure message”. Tutanota user experience feels very nice and smooth. Intuitive, logical, nothing new to learn. This is exactly what a privacy email alternative should look like. The basic option is 1 GB of free space that you can devote to your emails and contacts. Tutatona offers you a premium version. It’s possible to send encrypted messages via Tutanota’s application to external accounts. Mailfence.com secure and private email review This is another end-to-end encryption email service but unlike Tutanota, Mailfence supports OpenPGP so that you can manually exchange encryption keys independent from Mailfence servers. The website’s interface is also simple and clean-looking. Basic account will give you 200 MB in messages and additional 500 MB for documents. You can upgrade for 5 and 12 GB plan with unlimited calendars and contacts, or get a pro account with 30 GB in messages and 24 in documents for only a little over 8 bucks a month. Disroot.org protect your privacy review Disroot is one of the two services on this list that similarly to mailfence, enables you to use third party mail clients via POP or IMAP to store your messages locally. Disroot is an encrypted email service with SSL and TLS to transfer your messages as “envelope” and not a “postcard”. Protonmail.com Swiss-based encrypted and secure email review Swiss based encrypted email service developed by scientists from CERN and MIT, Protonmail offers top security and privacy in their end-to-end encrypted webmail application. Protonmail offers two-factor-authentification, but you can also create separate mailbox password.

What Is Email Encryption? | GoDaddy
Learn what email encryption is and how it keeps sensitive information safe. GoDaddy partners with Proofpoint to offer your business this protection. Visit: https://www.godaddy.com/business/office-365?cvosrc=video.youtube_organic.us_how-to&cvo_creative=bFDumuHlHs8isc=ythowto Your Office 365 email is safe sitting on our servers; but what about when it’s in transit? Watch this video to learn how GoDaddy email encryption protects your data between sender and recipient. The accessible nature of the Internet means between send and receipt, an email message is always at risk for interception. But even more often, emails are just sent to the wrong recipient. No big deal if you’re emailing a recipe to your Aunt. But what if you’re an attorney sending a contract to a client, or an insurance broker providing policy and premium details to a customer? Since most emails are sent unencrypted, or in plain text, an intercepted or misdirected email in these situations can create big problems for both parties. Email encryption encodes the contents of an email in a special way during transit, which can only be decoded with a unique cypher. To decipher the message, the email recipient must to log into a portal to view it. So if a message is intercepted or just ends up in the wrong hands, unauthorized parties cannot read its contents. GoDaddy has partnered with Proofpoint to offer an email encryption add on to your GoDaddy Office 365 email account for a monthly fee. This solution uses the same 256-bit encryption technology employed by some of the largest banks and corporations to protect their valuable data. While email encryption is a great add-on for anyone who sends sensitive information over the Internet, it’s a critical requirement for businesses in regulated industries For financial services, insurance, health care, legal, and real estate businesses, email encryption is a necessity to ensure they meet or exceed their industry’s prescribed level of protection for customer information. Whether your business is part of a regulated industry, or you just want an extra safeguard when sending sensitive data via email, adding encryption to your GoDaddy Office 365 account is great way to ensure your emails are ONLY read by the intended recipient. #EmailEncryption #EncryptedEmail #GoDaddy #GoDaddyEmail

Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

The Godaddy Email Encryption service comes with a default policy where users are instructed to type the word [encrypt] in square brackets into the subject line any time they want to send an encrypted message. So as you can see I’m creating a message that I want to send encrypted to Noirin who works at my local bank. I’ve added the word [encrypt] in square brackets into the subject line, and I’ve attached a file that I want to send to them. Now that the email has been sent, you’ll notice that the encryption service has sent me a confirmation email letting me know that my message was sent encrypted. When Noirin opens her email you will see that she has received a notification email letting her know that she’s received an encrypted email from me, with instructions to click on the “view encrypted email” button. When Noirin clicks the button it will open a browser and take her to the Proofpoint secure mail portal, where she will need to log in in order to view the encrypted message. If she is a first time user of the service she will have to create a password and register. Please note that we do have strict password requirements at this stage. After registering Noirin will receive a confirmation email that when clicked will take her to the secure cloud portal. She will then be able to log in and view the encrypted email, she can download the file that was attached, and she can reply to the message. The reply will come all the way through to my inbox, where I won’t have to login to the secure mail portal to view the reply. This concludes our demo, thanks for watching.

Secure email: Share your public key SAFELY using Symantec's PGP Keyserver
The link covered in the video: https://keyserver.pgp.com Previous video that shows how to securely encrypt emails: https://www.youtube.com/watch?v=6nNibHgbI_w This is the video I promised you at the end of the previous video where I show you how to securely email people using gpg4win encryption. This video covers the use of a special kind of keyserver which validates the email address of the key, so that you only can find one key in the directory, the real key for that person. It does not matter if you use Symantec's PGP software, gnupg aka gpg, gpg4win or any other variant because they are essentially the same technology and you can upload and share your keys no matter which software you made your key with. This keyserver is owned by Symantec (a big name in security). If you find this video useful please like it and subscribe to the channel :) Enjoy! This video would fall into the category of internet security essentials.
