List of reasons to whitelist websites through firewall Gambling and pornography sites tend to be blocked because as users or employees may access inappropriate content.Some companies block social media sites like Facebook because employees may become distracted if they are allowed to access them during work hours.The website might contain malware and viruses, which could affect your computer if it is accessed through the company’s network.This is done for security reasons, but can be inconvenient for employees and other people that need access to those sites. Some companies and organizations have a firewall setup to block access to certain websites. List of reasons why websites are untrusted By whitelisting a site with your firewall, you ensure that users will not receive any network errors when they visit this site and instead allows them access at all times. This usually is a good thing, but it can sometimes be an inconvenience for employees that need to whitelist the website. This makes sense because you wouldn’t want to allow all websites access to your network due to security reasons. These websites are blocked by default on most firewalls, and whitelisting a website requires special permissions within the firewall. Untrusted websites are blocked on most firewalls to ensure that users are safe. When a firewall rule is triggered, it logs an event in the Deep Security Manager and records the packet data.Quick Guide to Allowing Websites Behind a Firewall Untrusted Websites You can select Any Flags or individually select the following flags: Support for IP-based frame types is as follows:ĪRP and REVARP frame types only support using MAC addresses as packet sources and destinations. You can use a previously created IP, MAC or port list. Select a combination of IP and MAC addresses, and if available for the frame type, Port and Specific Flags for the Packet Source and Packet Destination. Select a Packet Source and Packet Destination If you select "Other" as the protocol, you also need to enter a protocol number. If you select the Internet Protocol (IP) frame type, you need to select the transport Protocol. Note that the Virtual Appliance does not have these restrictions and can examine all frame types, regardless of the operating system of the virtual machine it is protecting. Packets with other frame types will be allowed through. On Solaris, Deep Security Agents will only examine packets with an IP frame type, and Linux Agents will only examine packets with IP or ARP frame types. The rule can allow traffic (it will exclusively allow traffic defined by this rule.).The rule can deny traffic (it will deny traffic defined by this rule.).The rule can force allow defined traffic (it will allow traffic defined by this rule without excluding any other traffic.).This action will make entries in the logs but will not process traffic. If the protocol is TCP or UDP and the traffic direction is "outgoing", the source ports must be one or more specified ports (Not "Any"), and the destination ports must be "Any".If the protocol is TCP or UDP and the traffic direction is "incoming", the destination ports must be one or more specified ports (not "Any"), and the source ports must be "Any".Source and Destination IP and MAC: all "Any".Protocol: TCP, UDP, or other IP protocol.You can achieve maximum throughput performance on a bypass rule with the following settings: You can select from one of the following five actions: Select the Action that the rule should perform on packets. Make a note of when and why rules were created or deleted for easier firewall maintenance. It is good practice to document all firewall rule changes in the Description field of the firewall rule. Select the behavior and protocol of the ruleĮnter a Name and Description for the rule. To edit the new rule, select it and then click Properties. Right-click the rule in the Firewall Rules list and then click Duplicate. Copy and then modify an existing rule.There are three ways to add a new firewall rule on the Policies > Common Objects > Rules > Firewall Rules page. See policies and computers a rule is assigned to.When you're done with your firewall rule, you can also learn how to: Select a Packet Source and Packet Destination.Select the behavior and protocol of the rule.To create a new firewall rule, you need to:

For information on how to configure the firewall module, see Set up the Deep Security firewall. This article specifically covers how to create a firewall rule. Firewall rules can be assigned to a policy or directly to a computer. Firewall rules examine the control information in individual packets, and either block or allow them according to the criteria that you define.
