The principle of least privilege dictates creating separate, specific rules. The inbound and outbound traffic flows serve different purposes and have different risk profiles. A dedicated outbound rule should specify only the required destination (the third-party API) and service (e.g., HTTPS/TCP 443), minimizing the attack surface. A single combined rule or an ‘any’ outbound rule is too permissive.

Check Point policy enforcement uses first-match logic. A rule with Source=Any, Destination=Any, Service=Any placed at the top will match all traffic, and the inspection will stop there. Any more specific, potentially restrictive rules placed below it will never be evaluated or applied, creating a critical security gap known as rule shadowing.

For a large group of devices (hundreds of sensors) on a dedicated segment that share the same traffic pattern, the most efficient and clear method is to represent them by their subnet. Using a Network object for the subnet (e.g., 10.10.30.0/24) is easier to manage than hundreds of individual objects or a large group, and is more secure and specific than using ‘Any’.

Check Point’s Time objects allow you to define specific time constraints for a security rule. You can create a Time object that defines a single time window (e.g., starting now and ending 8 hours later) and attach it to the rule. The rule will only be active during that window and will automatically become inactive afterward, providing secure, temporary access.

Rule number 0 in SmartView Tracker logs refers to the implicit Cleanup rule. This rule is not visible in the standard rule base but is always present at the end of the inspection chain. If traffic does not match any of the explicitly defined rules above it, it is matched by the Cleanup rule, which by default drops and logs the traffic. This is a key indicator that the user’s traffic is not being permitted by any existing policy rule.

Check Point allows for granular policy-based inspection. The correct method is to create a more specific rule that matches only the finance subnet’s web traffic (Source: Finance Subnet, Service: HTTP, HTTPS). On this specific rule, you enable and configure the DLP software blade. This ensures the DLP inspection resources are applied precisely where needed, following the policy requirement without impacting other network traffic.

For a rule intended to allow standard DNS resolution for users, both TCP and UDP on port 53 are legitimate and necessary for proper functionality. The most efficient and clear method is to use a Service Group containing both the ‘domain-udp’ and ‘domain-tcp’ objects. This ensures the rule allows the complete, legitimate DNS protocol suite in a single, manageable policy entry.

Once VPN users authenticate, their encrypted traffic is decrypted at the gateway and enters the firewall’s inspection process as clear-text traffic originating from the VPN IP pool (a designated subnet). For this traffic to reach internal servers, there must be explicit Access Control rules that permit traffic from the VPN subnet (source) to the desired internal networks (destination) for the required services. The absence of these rules is a common cause for this symptom.

To report on successful connections, you need logs where the firewall action was ‘Accept’. Filtering by the specific destination (the database server) narrows the scope to traffic headed to that asset. Combining these two filters (Destination = DB Server, Action = Accept) will show all logged, permitted connections to that server, which is precisely what management requested. Filtering without the Action would include dropped connection attempts, which are not ‘successful’.
