EFail Flaw: Encryption Alone Does Not Protect Your Email

Email EncryptionAs reported last week by eWeek and others, researched found two flaws that allow hackers with access to email accounts to read emails encrypted with OpenPGP and S/MIME.  This is significant for two reasons:

  1. These standards are available for us in almost every email client
  2. Budget-conscious users often relay on public-domain or free tools to use OpenPGP or S/MIME for email encryption

As noted in the eWeek article, 23 of 35 email clients tested as of the publication date were vulnerable.  While the actual risk from EFail is currently moderately low — hackers need access to the encrypted emails before they can exploit EFail, the rate of identity compromise is on the rise. Secondary threats, such as EFail, will become a more prominent form of attack in the future.

Free Encryption Solutions Often Lack Sufficient Protection

Robust email security and encryption services include features, such as validation of digital signatures, that ensure the integrity of encrypted email messages.

Furthermore, solutions, like ZixEncrypt, control both ends of the encryption process, so any messages (with or without S/MIME encrypted attachments) with an invalid or missing digital signature get bounced. Integrity checks prevent the delivery of compromised messages, thereby preventing exposure.

As you face an increasing need to secure email communications, the robust features in services like ZixEncrypt create a value proposition most businesses cannot and should not ignore.

What is Slowing Down Your Internet? 5 Things Hurting Your Connection Speed

what could be slowing down your internet speed

Bad WiFi service frustrates employees, hurts productivity, and can send customers to your competitors. Even if you use your wireless access point (AP) vendor’s management tool, there are still things that may be hurting your WiFi service quality or slowing down your internet speed without your knowledge. Read on below to learn about network connectivity, and the top five issues we usually see slowing down your internet speed.

Here are five thing that are likely slowing down your internet speed

  1. Network traffic actually transmitted over the air:
    APs know that they attempted to transmit data to a client, but cannot detect if a malfunction prevented transmissions.  Wireless access points cannot detect their own transmission problems, such as dropped packets, chatter, and jitter.
  2. Clients consuming channel bandwidth that are not connected to your infrastructure:
    Not every device using channel bandwidth connects to your network. These devices often interfere with connected traffic, hurting performance for others.
  3. Misconfiguration within your infrastructure:
    APs cannot self-detect if they are configured improperly or if neighboring APs are creating interference. APs are not clients on the network, so they can only see what they transmit and what they receive.
  4. Clients connected to APs not managed by your AP controller:
    While your AP management tool may identify unmanaged or unauthorized APs on your network, they cannot detect or analyze clients connected to those APs and/or the impact these unmanaged devices have on your WiFi performance.
  5. Interference from devices and networks outside of your control:
    Vendor AP management tools are built to manage the vendor’s APs. These tools do not identify or analyze neighboring networks that interfere with yours. Bandwidth and channel conflicts go undetected and unresolved.

Your vendor AP manager misses these issues because your APs are not WiFi clients.

How to Fix Slow WiFi Speed

The best way to monitor and manage WiFi performance and reliability is to place a passive sensor client in your environment.  Unlike expensive WiFi assessments of the past, done by on-site technicians lugging around specially equipped computers and meters, innovative services like the Wyebot Wireless Intelligence Platform™ (WIP) give you a plug-and-go solution for about 1/10th the cost.  WIP is a vendor agnostic tool that can see and monitor your entire WiFi environment, analyze and prioritize issues with alerts, make knowledge-driven solution recommendations, and provide remote network testing tools.

Tools like Wyebot help you ensure your WiFi network best serves your business.

WiFi Quality is About the User Experience

WiFi QualityAn ever increasing number of businesses are learning that WiFi is more than a convenient network connection.

  • Restaurants, bars, and coffee shops that want patrons to linger and spend more lose business when customers can’t check the score, answer an email, or scan their social apps.
  • When your mobile app doesn’t work in your establishment because of poor WiFi service quality, your patrons go elsewhere.
  • WiFi quality influences which conference rooms get booked, where teams choose to huddle, where individuals choose to sit and work, and where people choose to socialize.

WiFi service quality is becoming a competitive factor that can help or hurt your business.

Most network managers rely on vendor management tools to monitor and control their wireless Access Points (APs). These tools provide basic statistics on traffic volume and patterns.  The more sophisticated solutions provide cool looking color-coded heat mats that overlay WiFi signal strength onto blueprints of your business. Some tools even use APs to triangulate users’ locations within their business.

What vendor AP management tools do not show you, however, is the client experience. You can have great WiFi signal coverage, but applications time-out if client devices experience too much interference. Your network may be setup to support a high density of users, but if clients end AP-hopping for signal strength, management overhead can cripple performance.

To understand WiFi quality: Understand the user experience.

By definition, your Access Points are not and cannot be clients on your WiFi network. The data your APs gather represents only what goes in and out of (or is simulated by) each Access Point. WiFi clients will see your network performance and reliability differently than your APs.

Think of it this way.  A chef creates a new signature dish. The chef knows that she’s used the best, freshest ingredients. The chef has sampled dozens of variations to get the taste just right.  The chef believes that this her best new meal ever. Even so, a few, many, most, or all customers may not like the taste, texture, or presentation of the meal. Fortunately, WiFi quality and reliability is not subject to personal taste and preferences; WiFi service quality is determined by the client experience.

The only way to understand, monitor, and manage WiFi service quality is to monitor your network from a client.

Historically, this has meant expensive service engagements in which technicians bring in monitoring and analysis systems for a “point in time” assessment. These assessments, which can cost thousands of dollars and only capture one point in time, are beyond the budget of most small and midsize businesses and schools.

New solutions, however, provide vendor-agnostic analyses of your WiFi network using passive sensor WiFi clients, prioritize identification of service issues, and offer knowledge-driven recommended solutions.  With the Wyebot Wireless Intelligence Platform™ (WIP), for example, in most instances we can provide periodic WiFi Assessments for less than 1/10th the cost of a traditional assessments. Ongoing monitoring becomes affordable for nearly all businesses and schools, the the added value of historical data analysis, real-time alerts, and remote network testing.

If your business relies on WiFi, you can now afford to make sure your WiFi network is reliable and performs well.
