User ID integration

10. Relaying UserID information using XML example

In this lecture, we'll talk about the anti-spyware configuration. Palo Alto is another content ID feature that Palo Alto is able to provide chosen signatures to identify spyware on the network. The way it does this is by matching against signatures. It can also be done with DNS learning to determine if there are any machines affected by spyware on your network. By default, there are two anti-spy profiles. The default and then the strict profile Let's take a look at the difference between the two. The default profile For critical, it takes the defaultaction of the signature simple.It uses the default value for "high. So basically, it takes the default action of all the signatures. So if we take a look at all the signatures here, click on Show all signatures. You can see what the signature default is. If you are going to be using the default policy,you will be subject to the default action that's in the rules and you will not have any control over the action other than to take the default. If you're using the default policy, it will only alert on DNS signatures. So DNS signatures are basically your clients' attempts to reach command and control IP addresses, which is an indication of the machine infected with spyware. Let's take a look at the rules. The difference between the default and strict isstrict would be reset for both clients and servers in the event of a critical high medium. The exception tab allows you to make exceptions for signatures that might be false positives for your environment.

DNS signatures are configured to block So for DNS signatures, in the event of strict, it's set to block, and then you can create your own. So we're going to go ahead and create an outbound policy and then we're going to add rules. There are different categories as well. You can make your policy based on the different categories of malware. Is it Edwar, backdoor, botnet, browser,hijack, data theft, keylogger network, peer-to-peer communication, and spyware? So those are different categories. I basically see spyware as a risk no matter what. So I'd like to take action against the higher medium of reselling the connection. The actions that you can do are allow alert, drop,reset, client reset, server reset, reset both, and block IP. Block IP is the most intrusive because it's going to block the IP of the client that's infected by spyware. Either reset or remove. We'll go ahead and do both resets. You can packet capture the traffic this way. You can do some forensics on it to determine what the communication was between the client and the server.

You can do single packet capture or you can do extended packet capture. It's up to you. If you're going to do extended packet capture and you have a lot of traffic in your environment, you might underestimate the amount of disc space consumed on your firewall. I'm going to do extended packet capture, but we'll set this policy for critical high, medium, and low. It's better to make the action be alert. Maybe if you want to investigate further, maybe a single packet capture. This way, you can determine if this is a false positive or not. And then we'll call this low informational. Click "okay" under exceptions. This is where you can make exceptions for signatures that might be triggering falsely for your environment. You can show all the signatures, and you can make exceptions for signatures. You can see all the signatures here. 122 pages. There are quite a lot of them. You can click on any of them and see the details, or you can specify an exception for a signature to be allowed. For example, this is an exception you can make. Let's say this signature is falsely triggering, then you can make it allow DNS signatures. DNS signatures allow you to monitor DNS traffic that is leaving your network and determine if there is any spyware or malware command and controllookup from clients in your environment.

And then you can allow or block those signatures, you can block those DNSqueries, or you can sync hold them. What sync holds allows you to do is send traffic to a specific IP address in your environment, and this way you can do further investigation into which machine. Clients typically do not query the DNS public DNS directly in the environment; instead, they go through your DNS server. So because of that, you wouldn't know exactly which client was the one that did the DNS query because the DNS query would be coming from your internal DNS server. So in order to get around that, you can sync hold, which means it's going to send traffic to an internal IP address on maybe yourIRS server, an internal IRS server, or maybe an internal server that you can do intelligent things like determining the actual client IP address that is searching for this DNS query that points to spyware. So a sync call is a great way to accomplish this.

Enabling passive monitoring enables the firewall to passively monitor DNS traffic that passes through the firewall. Determine if there's any DNSmatching signature against spyware. You can also do single packet capture or extended packet capture. So we're going to sync hold IPV4 to an IP address and then we can sync hold to an IP address on the firewall. So ten one, and this is going to be the loopback address that we're going to create on the firewall. We're going to go to network loopback. We'll add a loopback address, loop back one, and then we'll specify this to be the virtual router default and then the security zone trust and give it an IP address of ten (132). We'll go ahead and put this in a new security zone. I will call this zone "the sinkhole". This way, we can create a rule or policy on the firewall. This rule can allow us to alert clients that are trying to reach the Sync Hall.

Okay, we went ahead and created a new zone called Sync Hall. And then if a client machine on the internal network is infected, it's going to try to reach this IP address, which is in the sinkhole security zone. So now we can create a policy. We'll call this policy something like Sinkhole DNS, and then we'll specify the source to be trusted and the destination to be sinkhole. And then we're going to specify the permit. This will allow us to log traffic that is trying to reach the sync hole. So basically, what's going to happen is that the firewall will log the communication between clients and the sync hole. You can configure logix in your sync log server to notify you if any traffic is received from the rule synchro. You can do some intelligent alerting and such. So this will allow us to take another level of action. If a client on the internal network attempts to connect to the Sync Hold IP address, this Sync Hold IP address is used. Which is an IP address that you send to clients in response to their trying to resolve malware or spyware sites.

It will basically send them to school. This client would ping the sync host IP address and then any such events that are seen on the monitoring logs on your firewall. You can turn it on. If you are falling back to a syslog server and you want to trigger an alert based on receiving such traffic or logs hitting such a rule,this creates the anti-spyware security profile. Now we need to apply for a policy. We're going to go to policies, and then we'll find all the outbound traffic and then add this profile to the list of profiles that the firewall would do content inspection against. So let's find a trust to untrust rules. Allow yourself to trust and untrust. So this one will go ahead and add the antipower profile and then when you add it, you will see it here. And then, since this is blocked, we don't need to URL filtering rules, but we also need to do the spyware protection. So as we progress through the lectures, we build this profile, and then I'll show you later on how to group them in an easy-to-manage way. Now that you've completed this, you should go ahead and commit, and then commit to the changes. In the next lecture, I'll show you how to create a custom spyware signature so you can make sure your anti-spyware is working correctly.

11. User ID mapping using Syslog Messages example

In this lecture we will see how to configure the Palo Alto Firewall to receive SYSLOGinformation and then map IP addresses to users. In our example here, this hypothetical scenario, we have users connect to the any connect VPN and all your traffic goes out to the Internet using the Palo Alto Firewall. So we want to make restrictions based on user ID on the Palo Alto firewall. So in this case, since the SA doesn't support agents from Palo Alto, we can use Syslog to send Syslog information from the SA to the Palato firewall. This way, it can get the user to IP mapping from the essay on the ASA itself. We just basically need to enable logging and send the information to the IP address of the Palo Alto Firewall. Two steps need to be in place to be able to The first step is the interface configuration. The management profile needs to have the UDP Syslog listener configured.

So if we look at the trust interface, we see that we have the management profile trust. So we need to go to the management profile and add user ID syslog Listener UDP. The next step we have to do is go to Device User Identification and then we're going to add it under server monitor.We can add it as a monitor and specify that the type is Syslog server. We're going to put in the IP address of the ASE interface that's sending the Syslog events and specify UDP. And in the filter we're going to specify Cisco, AC, and e-connect v1, which is an aSyslog filter that's been pre-created by Palo Alto. Click "okay." And then when you go ahead and commit, commit. So when users connect to the ASA, they will get an IP address and, basically, the AC will send this Syslog message to the Palo Alto Firewall. That Syslock message will assist Palo Alto in determining who is logging in from this IP address. Click on administrator here and we're going to put the domain name lab. We need to add that as well, so we know which domain to associate with that user ID. And then I'm going to go ahead and connect to the interconnect, and basically, when I connect to any connect, the AC will send a Systlog message to the Palo Alto Firewall. So if we do show user IP user mapping,we see that the IP address information came from the Sydney log event that was received. That basically helps identify which users are coming from which IP address.

Threat Prevention

1. AntiVirius configuration

In this lecture, we'll talk about the antivirus feature. The antivirus engine detects and blocks viruses, spyware, phone, home spyware, downloads,botnets, worms, and Trojans. Additional features above and beyond protect your network from a wide range of threats. include inline streambased malware protection against malware embedded within compressed files and web content, DNS-based botnet analysis to reveal rapidly evolving malware networks and malicious websites, and HTML and malicious JavaScript protection. You can also leverage the SSL decryption within the app ID to block viruses embedded in SSL traffic. The key advantage of the PaloAlto solution is that it's stream-based. It takes the stream of traffic and dynamically analyses it for antivirus signatures. The Palo Alto Network Antivirus engine uses tree-based scanning to inspect your traffic as soon as the first packet of a file is received. This eliminates the performance and latency issues associated with a traditional proxy or file-based approach.

As with IPS, a uniform signature format is used for virus scanning. The same process that is used by the IPS is also used by the antivirus scanner. It eliminates redundant processes common to multiple scanning engine solutions. Because the packet is looked at once, it's matched against IPS and it's matched against antivirus,and basically that gives it a more efficient way of processing the traffic. There's also the continuous research that Paul Alto does. It takes the information from the Wildfire solution that we're going to talk about in later lectures. The Wildfire solution allows Palo Alto users to dynamically analyse files in the cloud. In the Wildfire Cloud, this information is received by the Wildfire Cloud and is used to match the traffic for all the customers. So it's kind of a crowdsourcing solution for anti malware.under objects. There are security profiles and antivirus. There is a default policy that comes with the system. We're going to go ahead and create a policy for our environment. We're going to call this outbound. Ez. You can do a packet capture if the ML was spotted on the network and antivirus software was spotted.

There are different decoders that the Palo Alto Firewall uses to decode packets. SMB for file sharing, SMTP, IMAP, HTTP, and FTP. You can specify different actions. For example, you can allow, you can alert, you can drop,you can reset clients or reset servers, or reset both. If the Wildfire determines that there's malware, you can also determine what action you're going to take. Allow alert, drop, and reset. The Wildfire action allows the system to not only use the signature based on the third prevention, but also check the Wildfire database to see if there's any match for the file in question. I personally like to use the drop feature so that the traffic is dropped completely, and I'm going to specify to drop across all the protocols. And then you can make an application exception, so you can specify an exception for a specific application. For example, you can specify an application from the application list and change the action to "maybe alerts." You can also make a virus exception based on thread ID. So let's say there was a thread ID that is false positive and you know it's not correct and you need to pass the file across your environment.

You can make an exception based on threat ID. Typically, what happens is you see this in the logs and then you can make an exception for the threat ID. One crucial point is that you have to make sure that you are updating your system under Devices dynamic updates. There's an antivirus update that you can schedule. You can schedule this hourly, daily, weekly, or none. You can do a download and install or just download only.You can specify a download every x number of minutes from the start of the hour. You can do it ten minutes after the start of the hour. Let's say you have multiple schedules and you want to scatter them out. It's important to keep your system updated with the latest antivirus signatures. You can also make sure that you get updates on the wildfire. You can do this every 15 minutes, every 30 minutes, or every hour. Download and install it. So this way, your system is always up to date on the latest threats. Going back to our policy here,we saw two different actions.

You have the antivirus, the action antivirus, and the wildfire action. They do check different databases. The action checks the antivirus database, the wildfire action checks the wildfire database. You also have to make sure you have the proper licenses. In order for you to do the detection of viruses, you need to have a Threat Prevention License. The threat prevention licence gives you antivirus, anti-spyware, and vulnerability protection. So we created the antivirus and now we want to basically apply it to our traffic for it to detect any viruses going across the network. What you need to do is determine the type of traffic that you want to check and then add the profile for that traffic.

We'll go ahead and use pretty much all the traffic from trust to trust, and we are going to check for viruses. To do this, you open the firewall rule,go to action, and choose Profile, and specify the profile that you want to use. So we'll go ahead and since this is blocked, you don't need to check it. This rule here is blocked for URL filtering. Also, we want to make sure we check for viruses, so we'll select the interval profile we created. Also, for the general rule, we can now specify the antivirus that we created. antivirus profile that we created. So you see here a different icon popped under your profile and you can hover around it and see the name and that will basically give you coverage to protect you from viruses on your network. Of course you need to commit, and after committing,of course the traffic is protected from viruses.

2. Anti Spyware and DNS Sinkholing

In this lecture we'll talk about the anti-spyware configuration. Anti-Spyware is another content ID feature that Palo Alto is able to provide chooses signatures to identify spyware on the network. The way it does this is by matching against signatures. It can also be done with DNS learning to determine if there are any machines affected by spyware on your network. By default, there are two anti-spy profiles. The default and then the strict profile Let's take a look at the difference between the two. The default profile For critical, it takes the defaultaction of the signature simple.

It uses the default value for high. So basically, it takes the default action of all the signatures. So if we take a look at all the signatures here, click on Show all signatures. You can see what the signature default is. If you are going to be using the default policy,you will be subject to the default action that's in the rules and you will not have any control over the action other than to take the default.

If you're using the default policy, it will only alert on DNS signatures. So DNS signatures are basically your clients' trying to reach command and control IP addresses, which is an indication of the machine infected with spyware. Let's take a look at the rules. The difference between the default and strict isstrict would be reset for both clients and servers in the event of a critical high medium. The exception tab allows you to make exceptions for signatures that might be false positives for your environment. DNS signatures are configured to block. So for DNS signatures, in the event of strict, it's set to block, and then you can create your own. So we're going to go ahead and create an outbound policy and then we're going to add rules. There are different categories as well. You can make your policy based on the different categories of malware. Is it Edwar, backdoor, botnet, browser,hijack, data theft, keylogger network, peer-to-peer communication, and spyware? So those are different categories.

I basically see spyware as a risk no matter what. So I'd like to take action against the higher medium of reselling the connection. The actions that you can do are allow alert, drop,reset, client reset, server reset, reset both, and block IP. Block IP is the most intrusive because it's going to block the IP of the client that's infected by spyware. Either reset or drop. We'll go ahead and do both resets. You can packet capture the traffic this way. You can do some forensics on it to determine what the communication was between the client and the server. You can do single packet capture or you can do extended packet capture. It's up to you. If you're going to do extended packet capture and you have a lot of traffic in your environment, you might underestimate the amount of disc space consumed on your firewall. I'm going to do extended packet capture, but we'll set this policy for critical high, medium, and low.

It's better to make the action be alert. Maybe if you want to investigate further, maybe a single packet capture. This way, you can determine if this is a false positive or not. And then we'll call this low informational. Click "okay" under exceptions. This is where you can make exceptions for signatures that might be triggering falsely for your environment. You can show all signatures and you can make exceptions for signatures. You can see all the signatures here. 122 pages. There are quite a lot of them. You can click on any of them and see the details, or you can specify an exception for a signature to be allowed. For example, this is an exception you can make. Let's say this signature is falsely triggering, then you can make it allow DNS signatures. DNS signatures allow you to monitor DNS traffic that is leaving your network and determine if there is any spyware or malware command and controllookup from clients in your environment. And then you can allow or block those signatures, you can block those DNSqueries, or you can sync hold them. What sync holds allows you to do is send traffic to a specific IP address in your environment, and this way you can do further investigation into which machine.

Clients typically do not query the DNS public DNS directly in the environment; instead, they go through your DNS server. So because of that, you wouldn't know exactly which client was the one that did the DNS query because the DNS query would be coming from your internal DNS server. So in order to get around that, you can sync hold, which means it's going to send traffic to an internal IP address on maybe yourIRS server, an internal IRS server, or maybe an internal server that you can do intelligent things like determining the actual client IP address that wassearching for this DNS query that points to spyware. So a sync call is a great way to accomplish this. Enabling passive monitoring enables the firewall to passively monitor DNS traffic that passes through the firewall. Determine if there's any DNSmatching signature against spyware. You can also do single packet capture or extended packet capture. So we're going to sync hold IPV four to an IP address and then we can sync hold to an IP address on the firewall. So ten one, and this is going to be the loopback address that we're going to create on the firewall.

We're going to go to network loopback. We'll add a loopback address, loop back one, and then we'll specify this to be the virtual router default and then the security zone trustand give it an IP address of ten (132).We'll go ahead and put this in a new security zone. I will call this zone "sinkhole".This way, we can create a rule or policy on the firewall. This rule can allow us to alert clients that are trying to reach the Sync Hall. Okay, we went ahead and created a new zone called Sync Hall. And then if a client machine on the internal network is infected, it's going to try to reach this IP address, which is in the sinkhole security zone. So now we can create a policy. We'll call this policy something like Sinkhole DNS, and then we'll specify the source to be trusted and the destination to be sinkhole. And then we're going to specify to permit. This will allow us to log traffic that is trying to reach the sync hole. So basically, what's going to happen is the firewall will log the communication between clients and the sync hole. You can make logix in your sync log server to alert you if any of the traffic gets received from the rule synchall. You can do some intelligent alerting and such. So this will allow us to take another level of action.

If a client on the internal network attempts to connect to the Sync Hold IP address, this Sync Hold IP address is used. Which is an IP address that you send to clients in response to their trying to resolve malware or spyware sites. It will basically send them to the sychole. This client would ping the sync host IP address and then any such events that are seen on the monitoring logs on your firewall. You can turn it on. If you are falling to a syslog server and you want to trigger an alert based on receiving such traffic or logs hitting such a rule,this creates the anti-spyware security profile.

Now we need to apply to a policy. We're going to go to policies, and then we'll find all the outbound traffic and then add this profile to the list of profiles that the firewall would do content inspection against. So let's find a trust to untrust rules. Allow yourself to trust and untrust. So this one will go ahead and add the antipower profile and then when you add it, you will see it here. And then, since this is blocked, we don't need to URL filtering rules, but we also need to do the spyware protection. So as we progress through the lectures, we build this profile and then I'll show you later on how to group them in an easy to manage way. Now that you've completed this, you should go ahead and commit, and then commit to the changes. In the next lecture, I'll show you how to create a custom spyware signature so you can make sure your anti-spyware is working correctly.
