IT Support Dundee. If you’re looking to protect your Microsoft 365 environment from hackers, you should consider setting up multi-factor authentication. This feature will protect your cloud identities and can simplify your password policy by removing the need to manually change passwords. Another security measure that can prevent attacks on your Microsoft 365 environment is Smart Lockout, which automatically locks out unauthorized users when they are not logged into their accounts. These measures can also help you prevent data leakage and other risks.
Multi-factor authentication
If you want to protect Microsoft 365, one of the best ways is to implement multi-factor authentication (MFA). MFA allows users to sign in using a second factor, such as a phone number or a code, rather than a traditional password. You can also enable VPN access, which allows you to securely connect to your work network. For added security, you should also enable MFA for your email accounts and other online services.
IT Support Dundee. Using multi-factor authentication makes it impossible for hackers to access your Microsoft 365 account without your password. This authentication is a combination of biometrics and smartphone codes. A fingerprint or a smartphone code is much more difficult to steal than a pin. Using security defaults, which are preconfigured security settings that Microsoft provides to its customers, automatically enables multi-factor authentication for all user accounts.
Disabling OAuth
You can disable OAuth for Microsoft 365 in a couple of ways. First, you can run the Exchange Management Shell as an administrator. In the Get-IntraOrganization Connector cmdlet, look for the Enabled column and make sure that it’s False. This will disable the OAuth protocol for the exchange server, which will then no longer send email to your users. Instead, the server will relay SMTP through Office 365.
In September of this year, Microsoft will disable basic authentication. This will not affect unused tenant protocols, but will affect Exchange Online as well. You can expect to receive a 30-day warning. Microsoft may postpone the switch, but it is definitely coming soon. Regardless, you can prepare now to make the transition. In the meantime, consider using an alternative authentication method. Ultimately, you will save time and headaches by disabling OAuth for Microsoft 365.
Blocking unknown apps
When it comes to security, Microsoft 365 security configuration is only as good as the known attacks. And the threat landscape is constantly evolving, with new forms of attack surfacing everyday. To counteract these threats, you can use the various logging options in Microsoft 365, which can provide feedback and instructions on how to counter them. However, Microsoft security configurations must be monitored and evaluated regularly to maintain their effectiveness. Listed below are three steps you should take to stay safe.
First, you should enable Cloud Discovery for your organization. IT Support Dundee. In the “Cloud Discovery” pane, you should click the three dots at the end of each row to enable monitoring. This way, you can identify unsanctioned apps and recommend safe alternatives. After that, you can choose which apps to block and create a block script. When you are ready to use Cloud Discovery, you can configure the settings for Defender for Cloud Apps.
Smart Lockout
Smart Lockout is a default feature of Azure AD that separates attackers from valid users. It utilizes intelligence to distinguish legitimate users from unauthorized users. Organizations can customize this feature to prevent unauthorized access and enforce lockout periods. IT pros can set thresholds for Smart Lockout and set the duration for which it applies. The lockout duration is reset after the user has been locked out for more than a predetermined time.
The feature also helps prevent malicious activity, such as the entry of incorrect passwords. A malicious user can only access an account if they use the wrong password, so smart lockout prevents this from happening. It works by distinguishing between legitimate sign-ins and invalid attempts, preventing bad actors from logging in to accounts. This feature prevents attackers from accessing accounts and keeps legitimate users from losing access to important information.
Blocking attackers’ IP address
Blocking attackers’ IP addresses is one way to secure Microsoft 365 from cyber attacks. By blocking this type of communication, attackers are severely hindered, and it gives defenders time to shut down any entry points. Microsoft has released new capabilities to block these attacks, such as blocking the attackers’ IP addresses. This feature also identifies sign-in attempts from countries you have not been using. Additionally, it can detect leaked credentials that have been black marked and anonymous IP addresses. In order to successfully steal an account, an attacker must research the user’s profile and appear legit, and that’s where identity theft begins.
After the three-way TCP/IP handshake is complete, network protection will determine whether or not a website is blocked. If the site you’re trying to access is blocked, it will show up as ConnectionSuccess in the Microsoft 365 Defender portal. The site is blocked if the TCP layer detects that it’s blocked by the defender. This process can take several hours, depending on the type of website or IP address.
