Are You Using The Term ‘Server’ Correctly? (Spoiler: You Probably Aren’t)

It may well be the most misused term in technology – find out what the word ‘server’ means as opposed to the most common usage and why this is important.

Read the post here: Are You Using The Term ‘Server’ Correctly? (Spoiler: You Probably Aren’t)

5G networks advance in U.S. with expanded trials

In recent telecom news, the subject is 5G networks almost all the time, whether that means fixed broadband 5G mobile services trials. Telecom operators and equipment vendors have almost daily updates about 5G trials and rollout plans. AT&T and Verizon 5G have recently announced more specifics about their paths to 5G services in the U.S.

Beyond next-generation wireless, public Wi-Fi networks will get shored-up security with the release of the new WPA3 standard later this year. And on the subject of security, Verizon recently acquired a threat detection startup that uses machine learning to detect compromised equipment within an organization.

Here’s a closer look at the details.

Operators move forward on 5G networks

Verizon plans to launch 5G fixed wireless service in three to five cities later this year, but the launch is only “one slice” of its broad 5G and overall network plans, Verizon CTO Hans Vestberg said at a recent investor relations event. 

The 5G networks economics of Verizon’s fixed broadband service are good because the company is planning to move from operating seven vertical networks to one horizontal network that will work with a unified core, transport and fiber transport. Vestberg said Verizon will deploy an intelligent edge network that will be able to serve a particular customer whether the customer is on Verizon’s FiOS fiber service or its wireless LTE network. That will make the economics of Verizon’s 5G fixed broadband services better because most of the 5G network assets will be shared, Vestberg said.

The network evolution at Verizon will take years to complete, but it will be a major part of how Verizon reaches its target of saving $10 billion over the next four years, Vestberg added.

Looking toward 5G mobile services, AT&T plans to launch what it describes as mobile 5G services this year in 12 U.S. cities by using small cells deployed closer to the ground than the radios that support LTE placed at the top of towers. According to RCRWireless, AT&T’s first round of mobile 5G will use millimeter wave spectrum (between 30 GHz and 300 GHz) that offers higher capacity rates than low-band spectrum doesn’t propagate over long distances, so the radios need to be closer together than in LTE deployments. AT&T’s VP of network architecture Hank Kafka said millimeter wave can be placed on telephone poles, building rooftops or on towers but at a lower height than a macrocell because of the propagation characteristics. Out of 23 cities slated to receive AT&T’s 5G Evolution infrastructure — described as a foundation to AT&T’s evolution to full 5G while 5G standards are being finalized — AT&T hasn’t specified which cities will roll out the mobile services this year. Kafka said the rollouts will require significant zoning and permit negotiations.

Wi-Fi security upgrade incoming in 2018

Wi-Fi security is getting a long-awaited upgrade in 2018 later this year. The Wi-Fi Alliance recently announced plans for WPA3, a new security standard that will replace WPA2, a security protocol almost two decades old that is built in to protect almost every wireless device.

According to ZDNet, the move to WPA3 will make open Wi-Fi networks found in places like airports and coffee shops safer by applying individualized data encryption that will scramble the connection between each device and the router. The security will also block an attacker after excessive failed password guesses.

Verizon acquires autonomous threat detection startup

Verizon recently acquired Niddel, an autonomous threat detection service company that uses machine-learning to detect compromised or infected devices inside an organization. The acquisition price of the company was not disclosed. Founded in 2014, the company’s primary product, Niddel Magnet, is a subscription-based automated service that reduces the need for organizations to hire qualified security analysts when dealing with compromised machines.

According to TechCrunch (a publication owned by Verizon), Niddel uses a variety of information from more than 50 internal and external sources to track security threats that could affect machines in customer organizations.

“Using machine learning to improve information accuracy significantly reduces false positives and significantly improves our detection and response capabilities,” Alexander Schlager, Verizon’s executive director of security services, said in a statement. Verizon has said it will look to incorporate this Niddel’s technology into Verizon products and services in the coming months.

Compliance Manager tool aims to ease security audit process

underlying environment also means they are at Microsoft’s mercy for its answers on regulatory compliance audits. To address this situation and others, Microsoft developed a Compliance Manager tool that provides a real-time risk analysis of the different cloud workloads.

Over the last year, there has been an uptick in security measures in the enterprise. Two compliance regulations that come up frequently are the Health Insurance Portability and Accountability Act (HIPAA) and the General Data Protection Regulation (GDPR).

For HIPAA, introduced in 1996, the rise in hospital audits by the Office for Civil Rights and data breaches in recent years has many enterprises re-evaluating their security practices around patient data. GDPR is the compliance requirement that starts May 25, 2018, for organizations that handle the data of European Union citizens.

Most organizations that deal with HIPAA, GDPR or any other regulatory compliance know the difficulties associated with tracking results from audits, questionnaires, surveys and other standard operating procedures. The amount of information required to satisfy requests for compliance checklists and security assessments can overwhelm many Exchange administrators.

Regardless of the industry, the IT staff must address regulatory compliance audits; otherwise, the company can face financial and legal penalties. Microsoft released its Compliance Manager tool in November to assist IT in these efforts.

Compliance Manager tool offers compliance overview

Compliance Manager is a SaaS application located in the Service Trust Portal that features a dashboard summary of an organization’s data protection, compliance status and documentation details related to GDPR, HIPAA and other requirements.

The Compliance Manager tool provides an automated assessment of Microsoft workloads such as Office 365, Dynamics 365 and some in Azure. The utility suggests ways to boost compliance and data protection in the environment.

Compliance audits often require gathering the same information. Exchange administrators can save some time by using the Compliance Manager tool, which acts as a central repository of audit details and documentation. Admins can maintain this documentation over time and ensure they meet the compliance processes mandated by their teams.

The Compliance Manager tool is still in preview mode; Microsoft said it plans to have all the compliance templates set prior to May 2018, but anyone with an Office 365 subscription can sign up to test it.

For on-premises workloads, the Compliance Manager tool provides the requirements that need to be validated and evaluated by the administrators. Microsoft has not indicated if it will extend the automated assessment feature to any on-premises tools.

Compliance Manager assists administrators with compliance requirements across the different Microsoft workloads with full document management features and task management.

Compliance Manager assessments
The dashboard in the Compliance Manager tool gives a summary of the controls fulfilled by the customer and by Microsoft to meet a standard or regulation.

Compliance Manager breaks down compliance for a standard or regulation into assessments. Each assessment consists of controls mapped to a standard that are shared between Microsoft and the tenant. The dashboard shows which controls a customer and Microsoft have met to comply with a regulation or standard.

Administrators can use the Compliance Manager portal to manage control assignments for team members based on specific compliance requirements. Microsoft calls this task management feature action items, and it allocates different controls to individuals within the organization. This helps organize the tasks needed from each IT worker, such as data or email retention associated with GDPR, that Exchange administrators must complete. The platform enables administrators to set the priority and the individual responsible for it.

There are a few other features in the Compliance Manager tool worth noting:

  • A flexible platform that supports multiple regulations. In the initial preview release of the Compliance Manager tool, the application only supports GDPR, ISO 27001 and ISO 27018. Microsoft said it will add support for HIPAA and other regulatory standards, such as the National Institute of Standards and Technology Special Publication 800-53. Having one tool that covers the range of regulatory compliance requirements makes it a very attractive option for IT and Exchange administrators.
  • Coverage on multiple platforms. After Microsoft introduced Office 365, a number of Exchange Online administrators began to manage more than just Exchange workloads. It’s the responsibility of the IT department to ensure the interdependent workloads associated with Exchange Online meet compliance requirements. Microsoft includes assessments of Dynamics 365, Azure and the full Office 365 suite in the Compliance Manager tool to give IT full visibility into all the workloads under one compliance platform.

Compliance Manager tool shows promise

Microsoft has certainly delivered a good snapshot of what most compliance officers and administrators would like in its preview version of Compliance Manager. However, the tool only addresses three existing compliance requirements, when many in IT will want to see coverage extend to include the Payment Card Industry Data Security Standard, the Sarbanes-Oxley Act, HIPAA, Food and Drug Administration 21 Code of Federal Regulations part 11 and others. 

While there are a number of mature compliance and auditing tools in the market that offer more certifications and regulatory compliance, Compliance Manager eliminates the daunting task for administrators to produce detailed assessments under each of the compliance requirements. Some of this manual work includes interviewing Microsoft technical resources, gathering legal and written statements with certain security configurations, and, in some cases, hiring third-party auditors to validate the findings.

Microsoft will need to cover the rest of the compliance spectrum to encourage administrators to embrace this platform. But the platform is easy to use and addresses many of the concerns organizations have with the upcoming GDPR.

types of problems won’t disappear and might be more difficult to solve because you only have control and visibility into part of the application.

Various tools diagnose and troubleshoot problems with Autodiscover, a web service in Microsoft Exchange Online that enables mailbox admins to configure user profile settings.

Use the Outlook troubleshooting utility

Outlook has a built-in Autodiscover troubleshooting tool. To access it, hold down Ctrl and right-click the Outlook icon in the system tray. This brings up a box labeled “Test Email AutoConfiguration,” as shown in Figure 1.

Outlook Autodiscover tool
Figure 1: The Outlook Autodiscover tool displays how Office 365 sends Autodiscover information to the client.

This test shows how the client receives — or does not receive — Autodiscover information from Office 365. This tool runs as part of Outlook on the user’s PC: If the organization’s network configuration causes the Autodiscover problem, this tool responds as if the Autodiscover endpoint is offline. To get the correct results, run the test several times from both inside and outside the organization’s network.

Try the Remote Connectivity Analyzer

The Microsoft Remote Connectivity Analyzer is a web-based tool that identifies issues with Office 365 applications (Figure 2). Click on the Office 365 tab and select the Outlook Autodiscover test under Microsoft Office Outlook Connectivity Tests.

Microsoft Remote Connectivity Analyzer
Figure 2: Use the Microsoft Remote Connectivity Analyzer to address Office 365 problems.

The Microsoft Remote Connectivity Analyzer runs tests external to the organization’s network. If these tests pass, but the test run from the Outlook client does not, the issue resides with network access to Office 365.

Run the Support and Recovery Assistant

The last tool to try is the Microsoft Support and Recovery Assistant for Office 365 (Figure 3).

Support and Recovery Assistant
Figure 3: The Microsoft Support and Recovery Assistant for Office 365 walks the administrator through the diagnostic process with a series of questions to identify the Autodiscover problem.

The Support and Recovery Assistant asks a series of questions to assist administrators with various Office 365 issues. Depending on the test, the Support and Recovery Assistant might connect to Office 365 from the PC or from test resources that Microsoft maintains, such as the Remote Connectivity Analyzer.

If the Autodiscover issue remains unresolved, open a case with Microsoft Support.

Arm yourself for battle against an email virus outbreak

organization is hit with a major email virus outbreak.

Administrators should prepare on-premises Exchange — and themselves — to quickly stem the bleeding when that malware lands in a user’s inbox. And while the techniques to protect on-premises Exchange Server aren’t new, they are important steps to reduce the effects of an attack. Even if the antivirus scanner fails to detect the threat, there are ways to isolate affected mailboxes, slow the proliferation and even stop the spread of a virus. Have procedures, processes and scripts in place to fight off an email virus outbreak before trouble starts.

Study the risk chart

Every antivirus tool is different, so the risk chart in Figure 1 doesn’t include all the steps to take during an email virus outbreak. But it shows what to do within Exchange if the antivirus software or SMTP gateway cannot stop the threat. Armed with this plan, administrators have a clear course of action to help the system weather an attack.

Risk chart
Figure 1: This chart explains what action an administrator should perform based on the impact of the threat to the Exchange Server.

The risk chart also indicates the appropriate response based on the severity and distribution of the threat. For example, a widespread distribution of the destructive Locky ransomware warrants a far greater response than when the Tinba malware hits a single mailbox. Use this chart as a baseline to assemble a threat-response plan.

Clean the mailbox

If an outbreak gets beyond the gateway and desktop virus scanners, use the Exchange Management Shell to quickly run a script that will search-and-destroy the offending email from the mailbox. This will limit the damage.

With Exchange 2016, use the Search-Mailbox command with the –deletecontent switch. Be sure the administrative account has the Mailbox Import Export management role. Here is the example of the syntax:

search-mailbox “Bryant, Steve” -searchquery ‘Get rich now!!!’ -deletecontent

This command looks at the body of all messages in the mailbox for the string “Get rich now!!!” and purges those items from mailboxes. If an outbreak strikes, modify the command to search for specific phrases in the offending email and delete them. Be careful: This command will wipe results permanently. Administrators can execute this in a reporting mode as a test before using the purge script:

search-mailbox “Bryant, Steve” -searchquery ‘”Get rich now!!!”‘ -EstimateResultOnly

For large mailboxes or multiple mailboxes, the New-MailboxSearch command is an option because Search-Mailbox can only check one mailbox at a time. But there will be some differences in how this method removes data compared to other methods. More details about the New-MailboxSearch command are available here.

Scour email from multiple mailboxes

To search multiple mailboxes, admins can either scan them all or specify mailboxes with an input file. A search through all mailboxes is the easiest way to track down infected messages, but it also could be the slowest way to clean a mailbox, depending on how many mailboxes exist.

An organization with fewer than 1,000 mailboxes could use this command for fast results:

Get-mailbox –resultsizeunlimited | search-mailbox -searchquery ‘”Get rich now!!!”‘ -deletecontent

Use wildcards and filters to scan certain mailboxes. For example, use the following code to scan all users from a specific mailbox database:

Get-mailbox –database MBDB01 –resultsizeunlimited | search-mailbox -searchquery ‘”Get rich now!!!”‘ -deletecontent

Alternatively, this string will clean all mailboxes — one server at a time:

Get-mailbox –server MBSERVER01 –resultsizeunlimited | search-mailbox -searchquery ‘”Get rich now!!!”‘ -deletecontent

As with the single search, use the –EstimateResultOnly switch to ensure the script works as intended.

Another way to search specific mailboxes is to use an input file:

$InputFile = get-content “C:affectedusers.txt”

foreach ($line in $Inputfile)         {search-mailbox $line -searchquery ‘”Get rich now!!!”‘ -deletecontent}

Isolate the mailbox

If the IT staff cannot clean a mailbox fast enough to contain the virus, then it’s best to isolate that mailbox. Exchange 2016 can quarantine a mailbox if it senses the mailbox has destabilized the database. This function makes the mailbox unavailable. Here is an example of a quarantine setting with a length of 60 minutes:

Enable-MailboxQuarantine “Bryant, Steve” -Duration 00.00:60:00

The previous command without the –Duration switch keeps the mailbox in quarantine until another command returns the mailbox to service:

Disable-MailboxQuarantine “Bryant, Steve”

With quarantine, the mailbox is offline but cannot be cleaned. No one can access it.  

To allow mail delivery to the mailbox — but make it inaccessible to users — use the following command to restrict client access. The user cannot connect to the mailbox, but the administrator can clean it with PowerShell.

Set-CASMailbox “Bryant, Steve” -ActiveSyncEnabled $false -ImapEnabled $false -EwsEnabled $false -MAPIEnabled $false -OWAEnabled $false -PopEnabled $false -OWAforDevicesEnabled $false

Use wildcards to isolate multiple mailboxes at a time. To re-enable access, use the same script with $true:

Set-CASMailbox “Bryant, Steve” -ActiveSyncEnabled $true -ImapEnabled $true -EwsEnabled $true -MAPIEnabled $true -OWAEnabled $true -PopEnabled $true -OWAforDevicesEnabled $true

Slow the arrival of mail

If the outbreak continues to affect users and slows the system, adjust the influx of mail to reduce the invasion. Throttle the inbound SMTP connector to alleviate server strain and still permit functions to run.

The first step is to identify inbound internet connectors. For this example, we have a separate IP bound to each server. The names are consistent and start with Internet Receive Connector Server; we can run a script and set the details for those connectors. The default setting for the tarpitinterval parameter puts the SMTP response on a five-second delay.

get-receiveconnector | Where-Object {$_.identity -like “*internet*”} | select name, MaxInboundConnectionPerSource, tarpitinterval

Inbound internet connectors
Identify the inbound internet connectors.

 

Other settings will regulate email, but start with these. The idea is to ease the arrival of inbound messages and give IT more time to clean and isolate — without crippling connectivity.

This command reduces the number of connections per source from 20 to 5, and increases the tarpit interval from five seconds to 30 seconds:

get-receiveconnector | Where-Object {$_.identity -like “*internet*”} | set-receiveconnector -MaxInboundConnectionPerSource 5 –tarpitinterval 00:00:30

The command enables inbound mail to flow, but limits how many messages a single internet host can send at one time. Adjust these numbers as needed, but do not forget to put the settings back to defaults when the crisis is over.

If you haven’t created specific receive connectors for internet traffic, use the command below to work with “default” receive connectors. This also slows server-to-server traffic within the environment.

get-receiveconnector | Where-Object {$_.identity -like “*default*”} | set-receiveconnector -MaxInboundConnectionPerSource 5 –tarpitinterval 00:00:30

Stop mail from the attack source

If the severity or scope of the attack is severe enough, an administrator can stop all inbound internet traffic. For this, disable internet connectors. In this case, the environment has specific connectors for inbound internet traffic, which facilitates throttling and mail restrictions.

get-receiveconnector | Where-Object {$_.identity -like “*internet*”} | set-receiveconnector –Enabled $False

If your Exchange configuration doesn’t have named connectors for internet connectivity, you’ll need to find another way to disable inbound SMTP traffic at the firewall or gateway.

Slow all inbound mail

If the email virus outbreak uses the Exchange system to spread the infection, slow all receive connectors to give the staff more time to clean. This command sets the default receive connectors on all servers to hold back connections from all sources, including server-to-server transport:

get-receiveconnector | set-receiveconnector -MaxInboundConnectionPerSource 5 –tarpitinterval 00:00:30

This will slow mail delivery and allow SMTP queues to grow. Watch the queue drive closely and change the MaxInboundConnectionPerSource and tarpitinterval settings to adjust the speed until mail flow reaches a manageable rate.

Stop all inbound mail

In very drastic cases, stop all inbound mail flow to give IT time to clean mailboxes or prepare for a recovery scenario. Use this command to take that step:

get-receiveconnector | set-receiveconnector –Enabled $False

Isolate affected servers

In some situations, a specific site or server could experience an outbreak that’s worse than any other segment within the organization. Use this command to isolate a server, stop its transport service and halt all mail transfers:

Get-Service -Name MSExchangeTransport -ComputerName SERVERA | Stop-service

After the repairs, restart the service with Start-Service with this command:

Get-Service -Name MSExchangeTransport -ComputerName SERVERA | Start-service

Prepare for restoration

In some cases, an IT team won’t be able to clean the email virus outbreak completely because of time constraints or the amount of damage that Exchange data received. In these circumstances, the only solution might be to restore data from a backup.
