10. Use Descriptive Security Group Names


First of all, make sure you apply permissions to resources with securitygroups not individual accounts, this makes managing resources much easier.Next, don’t name your security groups with a generic name like helpdesk or HRTraining.When you have generic names like this they will get used on all kinds ofresources and you will have lost all control of security.And there is no easy way to see what all a security group has permissions to.Yes, there are tools that you can run but if you have a medium or large sizeenvironment this will be a huge task.Here is a recent example of how this can get out of control (real story).I was working with a client on cleaning up permissions to Active Directory.There where multiple security groups that had delegated permissions to ActiveDirectory.There was a group called helpdesk, another group IS Support and one morecalled AD Modify.I was under the impression only Helpdesk staff had rights to Active Directoryto reset passwords and unlock accounts.Come to find out these groups were used for other resources such as thehelpdesk software, network share and printers. So it included various ITstaff.Once I removed these groups I got phone calls from programmers and businessanalyst asking why they couldn’t reset users passwords anymore. Why on earthare programmers resetting user passwords?I clear precise Security group name would have prevented this from happening.If you don’t name the security group specific then it can be a catch all forpermissions to many other things.Here are some good examples of how to name groups.

15. Run Critical Infrastructure on latest Windows Operating System

Most connections start with a DNS query. All domain joined systems should beset up to use your local Windows DNS server.With this setup, you can log every internal and external DNS lookup. When aclient device makes a connection to a malicious site it will log that sitename in the DNS logs.These malicious domains are usually odd, random character domains that raisesred flags.Here are some screenshots of suspicious DNS lookups from my logs. Theserepeatedly show up in my logs for a handful of devices.I seriously doubt a user is trying to go to this site intentionally. Thesekinds of lookup need to be looked into to determine if it’s malicious or not.To view the DNS lookups you first need to enable the DNS debug logs on theWindows Servers.

Steps to enable DNS debug logs on Windows Server


Step 1: Open the DNS Management ConsoleStep 2: Right click and select propertiesStep 3: Click Debug Logging TabStep 4: Check the box “Log packets for debuggingOnce you have the debug logs setup you can import those logs into an analyzerto quickly spot malicious activity.You can also convert the log file to a csv to make it easier to read andfilter.

19. Use Latest ADFS and Azure Security Features


ADFS and Azure have some great security features. These features will helpwith password spraying, account compromise, phishing and so on.No matter what level of office 365 you are on there are some features youshould look into.Of course, the premium subscriptions have the best security features.ButMicrosoft does improve and add new features at every level (At least this iswhat I’ve noticed since being on Office 365).Here are some features that are worth looking into: * Smart Lockout – Uses algorithms to spot unusual sign on activity. * IP Lockout – Uses Microsoft’s database of known malicious IP addresses to block sign on ins. * Attack Simulations – You should be doing regular phishing tests to help train end users. Microsoft will be releasing phish simulator software very soon. * MFA Authentication – Microsoft’s 2 factor solution * Banned passwords – Checks passwords against a known list * Azure AD Connect Health – Provides several good reports * Custom bad passwords – Ability to add custom banned passwords to check against.I’m currently running a hybrid office 365 setup. In azure I can see severalrisky sign on reports.Azure alerted me to a sign on that came from China from one of our accounts.Some of these features are available with the latest ADFS version and some areincluded with office 365 subscription.Definitely check out all the available security features in ADFS, Office 365and Azure.Resources:https://cloudblogs.microsoft.com/enterprisemobility/2018/03/05/azure-ad-and-adfs-best-practices-defending-against-password-spray-attacks/
