Used LDAP for identifying user groups This means that adding an exception for the UTID would create an exception for the whole DNS Security Category, which is not something that is desired. Now I must tell you something, none of the changes took any effect yet. However, applications like YouTube, that make use of SSL,need to be decrypted by the firewall for their identification. Each interface must belong to a virtual router and a zone. Next, change the IP Address accordingly and enable or disable any management services as required. Notify me of follow-up comments by email. Thank you for this work Dennis. I hadnt thought about such an implication actually before but to the best of my knowledge it shouldnt. Yes it works now we need to configure NAT and Security policy for clients in the LAN. The only thing is that if another admin adds a second zone on the destination zone, that might cause some unwanted traffic Since SSL connections are encrypted, the firewall has no visibility into this traffic in order to identify it. DNS server addresses. The way that the DNS sinkhole works is illustrated by the following steps and diagram: Blocking instead of sinkholing these DNS queries would implicate the internal DNS server as requests are relayed through it. After determining the information of the final destination zone for the post NAT traffic, the firewall does a second security policy lookup to find a policy that allows traffic destined to the final destination zone, DMZ. Another way of controlling websites based on URL categories is to use URL filtering profiles. Configure primary and secondary DNS servers to be used. Some websites like YouTube use a certificate with wildcard name as the common name. In your scenario, I think I would call it a config issue/mistake. Rule B: The applications, DNS, Web-browsing, FTP traffic initiated from the Trust zone from IP 192.168.1.3 destined to the Untrust zone must be allowed. Similar to Cisco devices, Palo Alto Networks devices can be configured by web or CLI interface. If a six-tuple is matched against a security rule with no or limited security profiles, no scanning can take place until there is an application shift and the security policy is re-evaluated. Read the whitepaper Description An improper handling of exceptional conditions vulnerability exists in the DNS proxy feature of Palo Alto Networks PAN-OS software that enables a meddler-in-the-middle (MITM) to send specifically crafted traffic to the firewall that causes the service to restart unexpectedly. Normally it is used for data plane interfaces so that clients can use the interfaces of the Palo for its recursive DNS server. Since the firewall does a security policy lookup from top to bottom, all traffic from IP 192.168.1.3 matches Rule A and will be applied to the session. . Working knowledge of networking, shell scripting, MySQL, MS SQL, DNS, XML, Perl, and Palo Alto firewalls; Technical knowledge of web-based solutions; Advanced proficiency with operation and support of Redhat ES Linux or MS 2012+ Windows Server Operating Systems, with a working knowledge of the other.
