A : The firewall is the core of a well-defined network security policy. The goal of the Check Point Firewall Rule Base is to create rules that only allow the specified connections.

Q11 : What are the Basic Access Control Rules for all Rule Bases?
A : These are basic access control rules we recommend for all Rule Bases:
1. Stealth rule that prevents direct access to the Security Gateway.
2. Cleanup rule that drops all traffic that is not allowed by the earlier rules.
3. There is also an implied rule that drops all traffic, but you can use the Cleanup rule to log the traffic.

Q12 : How do you define Security Zones?

Make sure that there are different rules in the Firewall Rule Base that define traffic to and from the security zones.

Q13 : How do you prevent IP Spoofing?
A : Attackers use IP spoofing to make the IP address of a packet appear to be from a trusted source. This can bypass the Firewall to introduce malicious content and actions (malware and bot downloads, DoS attacks, unauthorized access, and so on) to your network.
Anti-Spoofing detects if a packet with an IP address that is, according to the topology, behind one interface, actually arrives from a different interface. For example, if a packet from an external network has an internal IP address, Anti-Spoofing blocks the packet.

Q14 : What’s the Bitmap Checkpoint?
A : Bitmap Checkpoint checks the bitmap images in your web page or application.

Q15 : How do you prevent IP Spoofing?
A : Attackers use IP spoofing to make the IP address of a packet appear to be from a trusted source. This can bypass the Firewall to introduce malicious content and actions (malware and bot downloads, DoS attacks, unauthorized access, and so on) to your network.

Q20 : Explain How do virtual corporations maintain confidentiality?
A : Encryption

Q21 : Explain Which of the following is the BEST method for managing users in an enterprise?

Q22 : What is the Packet Flow of Checkpoint firewall.
A : Layer 7 Inspection happens right after Destination NAT. If the traffic is to pass through the Medium-path, i.e. IPS/ ThreatPrevention/ UserCheck/ AppCheck/ URL Filtering. Streaming Library, Pattern matching, Sequence Check, etc…
After this Route Lookup happens and then Source NAT is done, followed by VPN-Encrypt and then L2 Lookup.
