Always test remote app performance with a WAN emulator
Many organizations deploy new applications for their remote site users without testing it on a WAN. Not testing these applications across a simulated WAN increases the possibility of performance issues during the early stages of usage because you have no idea how the application will perform once latency or jitter come in between the communication path of the client and server. If the application uses large amounts of bandwidth that causes congestion, then it can negatively affect the performance of other applications that share the bandwidth. A WAN emulator can enable you to measure the average bandwidth that an application may use before you deploy it. To read this article in full or to leave a comment, please click here

How to protect your network from ransomware attacks
Ransomware attacks are becoming more rampant now that criminals have learned they are an effective way to make money in a short amount of time. Attackers do not even need any programming skills to launch an attack because they can obtain code that is shared among the many hacker communities. There are even services that will collect the ransom via Bitcoin on behalf of the attackers and just require them to pay a commission. This all makes it more difficult for the authorities to identify an attacker.+ Also on Network World: Network vulnerability analysis 101: Free online training + Many small and medium-size businesses pay ransoms because they do not backup their data and do not have any other options available to recover their data. They sometimes face the decision of either paying the ransom or being forced out of business. Also, hospitals that do not back up all their critical patient data and are not able to retrieve it in a timely manner will immediately pay the ransom because it is critical to access records of patients who require immediate care. It can become a life-or-death situation for someone in intensive care.To read this article in full Continue reading

4 steps to planning a migration from IPv4 to IPv6
With the depletion of IPv4 addresses, more organizations are encouraged to transition over to using IPv6 addresses. Many organizations are noticing the benefits of the built-in security features of IPv6. Also, enterprise IT managers are observing that their service providers are successfully using IPv6, and this encourages them to move forward with it.To continue to ignore IPv6 could cause any number of potential problems, including an inability to immediately migrate to IPv6 when there is no longer a choice, loss of internet connectivity, and not being able to compete with organizations whose systems are configured for IPv6.To read this article in full or to leave a comment, please click here

Time to consider a move to IPv6
Organizations should consider migrating their network infrastructure and devices over to IPv6. It may be a challenge to persuade leadership to prioritize it over other projects such as cloud computing or big data migrations, but it is essential to start planning for a migration.Many service providers, such as Comcast, Verizon and AT&T, have already started using IPv6 addresses and are presently encouraging other organizations across the United States to do the same. The Internet Engineering Task Force (IETF) has encouraged organizations to move forward with these migrations for over a decade, and with more devices connecting to the internet, the need has increased.

Is protected health information safe in the cloud?
Many healthcare providers face the decision on if they should store protected health information (PHI) in the cloud. There are benefits and concerns to storing PHI in the cloud, and the decision to do so should be analyzed.PHI is any health-related or insurance payment information that is stored or managed by a healthcare provider that can identify a specific individual. Examples of PHI are patient names, addresses, Social Security numbers, X-ray images, lab results, insurance payment information and medical records. Even information about a patient’s planned future procedures is PHI. Government regulation of PHI is covered in the HIPPA Privacy Rule, and all healthcare providers in the United States must adhere to it or face fines.To read this article in full or to leave a comment, please click here

How to protect your data when using public Wi-Fi
Many people are not aware of this, but Wi-Fi hotspots at Starbucks, Barnes & Noble or your local hotel that offers it as a complimentary service are not safe for confidential browsing, performing financial transactions or for viewing your emails.Public Wi-Fi does not offer encryption for individuals using the same password and hotspot. Also, your signals are broadcast across the immediate area. It is easy for someone else within your vicinity to eavesdrop on your communication. An unskilled hacker can intercept your signal using a phony hotspot or a tampering software that can be found on a search engine.+ Also on Network World: 4 lesser-known Wi-Fi security threats and how to defend against them + The first task of a hacker is to get on the same network as the potential victim, then they can carry out that task with a public Wi-Fi network because they have the password. It does not matter if a network password is given out by the cashier or printed in your hotel room's welcome packet, once public, your security is compromised.To read this article in full or to leave a comment, please click here

How to protect against cross-site request forgery attacks
Cross-site request forgery (CSRF) attacks are becoming a more common attack method used by hackers. These attacks take advantage of the trust a website has for a user’s input and browser. The victim is tricked into performing a specific action they were not intending to do on a legitimate website; where they are authenticated to.CSRF attacks will use the identity and privileges that the victim has on the website to impersonate them and perform malicious activity or transactions. Attackers will attempt to take advantage of users who have login cookies stored in their browsers. Ecommerce sites that send cookies to store user authentication data are vulnerable to this attack.To read this article in full or to leave a comment, please click here

Internet VPN or MPLS for branch office IP phone communication?
Many businesses with branch offices that have IP-enabled phones must decide what type of circuit medium to use for their communication to the corporate headquarters site.Two of the most selected choices are a MPLS circuit or internet VPN. Both solutions have their pros and cons, and what is best can depend on your business requirements. Speed, quality of service (QoS), security and cost are the key factors you should consider when making this decision.Pros and cons of an internet VPN A significant advantage of using an internet VPN for communication is the cost. Most times, a branch site can use its existing internet connection for communication back to its headquarters. Usually, a 10 Mbps internet circuit costs much less than a 10 Mbps MPLS circuit. This can encourage a business to purchase more bandwidth for their branch site.To read this article in full or to leave a comment, please click here

Encryption critical for protecting mobile device data
If your mobile device contains any personal or private data, then it's crucial you protect it. In many cases, mobile devices contain sensitive information that, if breached, can cause significant problems for the users.For example, more people are storing copies of their driver’s license, employer data, insurance details, social security card, bank account information and passwords on their mobile device. Even personal pictures can be a major security concern. When applying for loans, instead of faxing, many people take pictures of important financial documents and email them to the requestor but do not delete the pictures from their phone.One very critical step you can take to secure this is to encrypt your mobile data.To read this article in full or to leave a comment, please click here
