Checkpoint 156-315.81 Exam With Confidence Using Practice Dumps

After trust has been established between the Check Point components, the Security Gateway IP address cannot be changed without re-establishing the trust. This is because the trust is based on the Secure Internal Communication (SIC) mechanism, which uses certificates to authenticate and encrypt the communication. The certificates are issued by the Internal Certificate Authority (ICA) of the Security Management Server / Domain Management Server, and contain the name and IP address of the component. Therefore, if the IP address of a component is changed, the certificate will become invalid and the trust will be lost. To restore the trust, the certificate must be renewed or reissued by the ICA12.

However, there are some exceptions to this rule. The Security Gateway name can be changed in command line without re-establishing trust, as long as the IP address remains the same. This is because the SIC mechanism does not rely on the hostname, but on the IP address and the SIC name (which is usually derived from the hostname, but can be manually changed). The Security Management Server name can be changed in SmartConsole without re-establishing trust, as long as the IP address remains the same. This is because SmartConsole uses a different mechanism to connect to the Security Management Server, which does not depend on the SIC certificate. The Security Management Server IP address can be changed without re-establishing trust, as long as some steps are followed to update the Check Point Registry file on the managed Security Gateways / Cluster Members / VSX Virtual Devices. This is because the Registry file contains the IP address of the ICA, which is used for certificate renewal. If the Registry file is not updated, then the certificate renewal will fail and the trust will be lost3.

 SmartEvent automatically defines events based on IPS (Intrusion Prevention System) alerts. IPS is a feature that detects and prevents malicious network traffic based on predefined or custom signatures. IPS alerts are generated when IPS detects an attack or an anomaly that matches a signature. SmartEvent collects and correlates IPS alerts from different gateways and displays them as events in SmartEventWeb. The other options are not automatically defined as events by SmartEvent. 

In R81, you can manage your Mobile Access Policy through the Unified Policy. The Unified Policy is a single policy that combines access control, threat prevention, data protection, and identity awareness. You can create rules for mobile access in the Unified Policy rulebase and apply them to mobile devices, users, and applications. You can also use the Mobile Access blade to configure additional settings for mobile access, such as authentication methods, VPN settings, and application portal.
