Over 200 years ago, Ailanthus altissima (tree-of-heaven) was introduced to the United States for use as an ornamental. The tree was recognized for its ability to tolerate various soil types and climates, rapid growth, high reproductive capacity, and lack of apparent insect pests or diseases. Initially, Ailanthus represented a reliable tree to plant in cities and revegetate disturbed areas. Today, however, the species is a common invader in many forests across the nation.
Podcast Season 2: Backcross (BONUS) How a Bird influences Beech Resistance In northern New England, New York, and the Maritimes where the beech bark disease is most severe, groups of disease resistant trees occasionally occur. Genetic studies reveal that trees in groups are families, and distribution patterns suggest that they were "planted" by blue jays. Listen here >>

ESL enables AD FS to differentiate between sign-in attempts from a familiar location for a user and sign-in attempts from what may be an attacker. AD FS can lock out attackers while letting valid users continue to use their accounts. This prevents and protects against denial-of-service and certain classes of password spray attacks on the user. ESL is available for AD FS in Windows Server 2016 and is built into AD FS in Windows Server 2019.
ESL is only available for the username and password authentication requests that come through the extranet with the Web Application Proxy or a 3rd party proxy. Any 3rd party proxy must support the MS-ADFSPIP protocol to be used in place of the Web Application Proxy, such as F5 BIG-IP Access Policy Manager. Consult the 3rd party proxy documentation to determine if the proxy supports the MS-ADFSPIP protocol.
All secondary nodes will contact the master node on each fresh login through Port 80 to learn the latest value of the bad password counts and new familiar location values, and update that node after the login is processed.
If the secondary node cannot contact the master, it will write error events into the AD FS admin log. Authentications will continue to be processed, but AD FS will only write the updated state locally. AD FS will retry contacting the master every 10 minutes and will switch back to the master once the master is available.
Pre-Auth Check: During an authentication request, ESL checks all presented IPs. These IPs will be a combination of network IP, forwarded IP, and the optional x-forwarded-for IP. In the audit logs, these IPs are listed in the field in the order of x-ms-forwarded-client-ip, x-forwarded-for, x-ms-proxy-client-ip.
Based on these IPs, AD FS determines if the request is from a familiar or unfamiliar location and then checks if the respective badPwdCount is less than the set threshold limit OR if the last failed attempt is happened longer than the observation window time frame. If one of these conditions is true, AD FS allows this transaction for further processing and credential validation. If both conditions are false, the account is already in a locked out state until the observation window passes. After the observation window passes, the user is allowed one attempt to authenticate. In 2019, AD FS will check against the appropriate threshold limit based on if the IP address matches a familiar location or not.
Failed Login: If the log-in fails the badPwdCount is increased. The user will go into a lockout state if the attacker sends more bad passwords to the system than the threshold allows. (badPwdCount > ExtranetLockoutThreshold)
If no resets occur, the account will be allowed a single password attempt against AD for each observation window. The account will return to the locked out state after that attempt and the observation window will restart. The badPwdCount value will only reset automatically after a successful password login.
When enabled, extranet lockout requires a primary domain controller (PDC). When disabled and configured as false, extranet lockout will fallback to another domain controller in case the PDC is unavailable.
Log only mode is intended to be a temporary state so that the system can learn login behavior prior to introducing lockout enforcement with the smart lockout behavior. The recommended duration for log-only mode is 3-7 days. If accounts are actively under attack, log-only mode must be run for a minimum of 24 hours.
Just Enough Administration (JEA) can be used to delegate AD FS commandlets to reset account lockouts. For example, Help Desk personnel can be delegated permissions to use ESL commandlets. For information on delegating permissions for using these cmdlets, see Delegate AD FS Powershell Commandlet Access to Non-Admin Users
Read the current account activity for a user account. The cmdlet always automatically connects to the farm master by using the Account Activity REST endpoint. Therefore, all data should always be consistent.
The recommended way to monitor user account activity is through Connect Health. Connect Health generates downloadable reporting on Risky IPs and bad password attempts. Each item in the Risky IP report shows aggregated information about failed AD FS sign-in activities that exceed designated threshold. Email notifications can be set to alert administrators as soon as this occurs with customizable email settings. For additional information and setup instructions, visit the Connect Health documentation.
While in log only mode, you can check the security audit log for lockout events. For any events found, you can check the user state using the Get-ADFSAccountActivity cmdlet to determine if the lockout occurred from familiar or unfamiliar IP addresses, and to double check the list of familiar IP addresses for that user.
A: With ESL enabled, AD FS tracks the account activity and known locations for users in the ADFSArtifactStore database. This database scales in size relative to the number of users and known locations tracked. When planning to enable ESL, you can estimate the size for the ADFSArtifactStore database to grow at a rate of up to 1GB per 100,000 users. If the AD FS farm is using the Windows Internal Database (WID), the default location for the database files is C:\Windows\WID\Data. To prevent filling this drive, ensure you have a minimum of 5GB of free storage before enabling ESL. In addition to disk storage, plan for total process memory to grow after enabling ESL by up to an additional 1GB of RAM for user populations of 500,000 or less.

The remedial investigation (RI) serves as the mechanism for collecting data to characterize site conditions, determine the nature of the waste, assess risk to human health and the environment, and conduct treatability testing to evaluate the potential performance and cost of the treatment technologies that are being considered. The feasibility study (FS) is the mechanism for the development, screening, and detailed evaluation of alternative remedial actions.
The RI and FS are conducted concurrently - data collected in the RI influence the development of remedial alternatives in the FS, which in turn affect the data needs and scope of treatability studies and additional field investigations. This phased approach encourages the continual scoping of the site characterization effort, which minimizes the collection of unnecessary data and maximizes data quality.
Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by a coronavirus, called SARS-associated coronavirus (SARS-CoV). SARS was first reported in Asia in February 2003. Over the next few months, the illness spread to more than two dozen countries in North America, South America, Europe, and Asia before the SARS global outbreak of 2003 was contained. This fact sheet gives basic information about the illness and what CDC did to control SARS in the United States.
According to the World Health Organization (WHO), a total of 8,098 people worldwide became sick with SARS during the 2003 outbreak. Of these, 774 died. In the United States, only eight people had laboratory evidence of SARS-CoV infection. All of these people had traveled to other parts of the world where SARS was spreading. SARS did not spread more widely in the community in the United States. See an update on SARS cases in the United States and worldwide as of December 2003. 2ff7e9595c
