A network security audit is a systematic evaluation of the security of a company’s information systems or network intermediary devices. The secureness of the network is evaluated using a few different sets of criteria, including measuring how well the devices conform to a set of established rules.

A thorough audit typically assesses the security of the system’s physical configuration, environment, software, information handling processes, and user practices. Traditionally, this process uses up a lot of valuable work hours, and can easily give inaccurate results if a tiny mistake is made anywhere along the way. But today, thanks to IP Fabric, these audits can be done in just under an hour.

Let’s take a look at some of the ways that IP Fabric can help you conduct a network security audit quickly.

Zone-based firewall rules verification

When it comes to successfully exporting security policies from SRX, IP Fabric gives you plenty of options.

The very easy one is to export the configuration between security zones to a text file and upload and send them to a customer. But it could be time-consuming and for non-Juniper technicians or managers. Also, for some people, it may be difficult to comprehend all the information in the configuration file.

Another option may be buying Junos Space software with the Security Director plugin. Or we could develop any customized script using Junos PyEZ library and export policies to multiple file formats. Both have their downsides.

With the IP Fabric platform it’s a bit different, you can:

Export any policies based on any zone, recorded source, or destination IP network or address.

Evaluate whether a policy definition conforms to established criteria, such as naming convention, correctly assigned IP networks, or logical order.

Verify historical correlations between past and present states thanks to IP Fabric’s Snapshot feature.

The use case for zone-based firewall rules

As a DC service provider, we have implemented a robust firewall cluster that currently supports more than 2000 clients. These clients request the security reports on a daily basis. The reports have to include the most current security policies configuration as well.

As a result of using the IP Fabric platform, we can create and export a comprehensive report anytime. Typically, fulfilling this request would take all day, but with IP Fabric, this entire process takes mere seconds to finish.

Verify 802.1X implementation verification

In a multivendor environment, enforcing an authentication means verifying that everything is what it claims to be. The purpose of an 802.1x verification is to help you accept or reject users requesting full-access to a network that uses 802.1X protocol.

Today, more and more companies shift towards tighter LAN security. They’re discovering that this process can cost them countless hours on implementation and verification if they try to do it on their own.

The use case for 802.1X implementation

In our company, we have more than 800 employees at 12 separate locations across the country. Using traditional methods, 802.1X protocol implementation is a long and arduous verification process. It can easily take more than three months to complete.

On the other hand, with the IP Fabric tool, we were able to tackle the verification process almost instantly. The tool simplifies and automates 802.1X verification, allowing us to run it as frequently as needed.

Access-lists compliance

Access-lists (or firewall filters) are a key feature when enhancing security across networks. They deny or grant access to devices based on specific combinations of source, destination IP, destination port, or other kinds of data. ACLs are fast and easy to implement. However, they are difficult to troubleshoot, even when appropriately applied. The IP Fabric platform compiles all of your ACLs into one place, allowing you to compare and correlate rules across all network devices easily.

The use case for an ACL compliance

Our MPLS network has thousands of network devices. To ensure compliance, we need to quickly verify that an up-to-date firewall filter is protecting management loopbacks. The IP Fabric platform can complete this task almost instantly and will give you a comprehensive device list that you can easily export and share.

Authentication, Authorization, and Accounting (AAA) information

The Authentication, Authorization, and Accounting system is used to track user activity on an IP-based network and control their access to network resources. When managing complex network infrastructure, it may be time-consuming to verify that all network nodes are configured along with the same AAA framework. 

The IP Fabric platform reduces the amount of time and hassle involved in AAA by giving you a highly detailed overview of all AAA-related information.

The use case for AAA compliance

A few months ago we decided to migrate all of our network devices to a new AAA server, which meant that we also agreed to a change of authorization rules.

The IP Fabric platform made tracking the progress of the migration effortless, meaning we had more time to focus on more critical tasks.

SNMP and Syslog configuration

Simple Network Management Protocol (SNMP) and Syslog are the key protocols for maintaining and monitoring network. A network engineer needs to ensure that both protocols are reporting properly to dedicated SNMP and Syslog servers. Above all, security should be applied correctly to this type of communication.

Thanks to IP Fabric, you’ll have a detailed structure report related to these protocols.

Use case SNMP compliance

Over the last 15 years, our network has evolved countless times, and we have lost track of correct SNMP configuration a few times along the way.

Since security is incredibly important to us, we designed the IP Fabric tool to help us verify that all SNMP traffic is sent to dedicated servers and that read-write rules are active at all times.
