![]() ![]() Preventing network scans will not let attackers gather the important information and will make attacks more difficult to implement. Network scanning provides attackers with crucial information, such as open ports, active operating systems and software, and network device status. The first step of an targeted attack is to collect information. Use IDS and IPS to detect and prevent network scans Even if an attacker managed to compromise an account or a machine, the step outlined above will narrow further attacker opportunities and prevent the privilege-escalation of an administrator or other devices what will result in decreasing the scale of the attack. The network information should be limited as it can be retrieved by attackers from a breached device. Configure policiesĬonfigure the policies to minimize the amount of network information available to users whose accounts can be compromised. On the devices protected by Kaspersky Endpoint Security for Windows, enable the Adaptive Anomaly Control component and switch the Activity of Script Engine and Frameworks rule into lock mode. Do not change the policy of restrictions of PowerShell (Set-ExecutionPolicy). Enable execution of the PowerShell scripts only to the accounts which need it. Disable execution of the unassigned PowerShell scripts using politics. Ransomware and fileless threats also use PowerShell for attacks. The PowerShell solution is frequently used for attacks on Windows-devices. Monitor lateral movement around a network and pay attention to outbound traffic as an attacker usually needs connection to external networks or external tools for data theft. Regularly check event logs and operational data for suspicious activity. Use two-step verification if possible, to minimize the risks of attackers obtain control over the network in case they have managed to get access to user credentials. Make sure administrator accounts are protected by strong passwords that are changed regularly (for example, every 3 months). Using these solutions, you can identify and monitor suspicious signals. KEDR and MDR will detect and prevent an attack beforehand. Use Kaspersky Endpoint Detection and Response (KEDR) or Kaspersky Managed Detection and Response (MDR) Kaspersky Endpoint Security for Windows protects shared folders from encrypting and can help to set strong passwords. Protect shared foldersĪttackers can use shared folders for file-encrypting, malware spreading and moving accross the network of your organization. ![]() ![]() For more information about the Remote Desktop features, see the Microsoft support website. Connect to Remote Desktop over your home or corporate network only. If you are using a public network, attackers can use the Remote Desktop features for gaining access yo your devices. To protect your personal data and your accounts from being hacked during remote connection, use strong passwords. Weak passwords can be easily guessed or cracked, what may result in acquiring the access to sensitive data by attackers. Use strong passwords for Windows accounts for remote connection Always check the sender’s address before opening emails or attachments. Cybercriminals aim to persuade you to open the attachment, which is why they title the emails as though they contained important information such as a court order, notice of intended prosecution, late fee notice or something similar. Ransomware often spreads via email attachments. Do not open attachments in emails from unknown senders To protect your files, create backup copies and store them in a cloud storage or a removable drive. Even in case of a successful ransomware or file-encrypting attack, the backup data can be recovered what will reduce the harmful effects of the attack. Regularly back up your files to the cloud or an external driveīackup and Restore is recommended to perform regularly. Ensure the following components are enabled: Turn on all protection components of Kaspersky applicationsĪll the components of Kaspersky applications are intended for maximum possible protection of devices and reducing the risks of ransomware infection. VPN applications that provide access for remote employees and serve as a gateway to your network.Browser plug-ins such as Flash, Silverlight, etc.Updates are the main means for improving security, stability and performance of the systems, they remove vulnerabilities and prevent attackers from using those. The updated software operates on the most recent patch which narrows opportunities for attackers. Keep your software, operating systems and Kaspersky applications updated, especially check patches that fix vulnerabilities on regular basis. Latest versions of Kaspersky applications feature a System Watcher component, which automatically creates backup copies of files if a suspicious program tries to access them. Kaspersky applications with latest databases will block an attack and prevent a malware from being installed on your computer. ![]()
