TCO of NSPM – Network Security Policy Management
Network Security Policy Management is an important need for any enterprise. TCO of NSPM is also important to decide on how to proceed. It may make sense to start with ROI of any NSPM solution. The Return on Investment (ROI) of network security policy management can be significant for organizations. Network security policy management involves implementing and enforcing policies and procedures to ensure the security of a company’s network infrastructure, including firewalls, routers, switches, and other network devices. Effective network security policy management can lead to several benefits that can provide a positive ROI for the organization. Some of these benefits include: There are several important achievements that can be supplied by any NSPM. However, as to TCO of the solution itself there may be some differences. These are some of the TCO components that need to be analysed: firewall manager usage, storage disk usage, effort needed to manage the system. To start with, firewall manager usage is generally a mandatory need for these solutions. So, if you have decided to use a firewall analyser or automation system and do not have any firewall manager already implemented then there will be this manager procurement cost you will be facing. On average in a 10-firewall infrastructure assuming they are belonging to same vendor. The cost would be 10K USD at minimum. Calculalation of a TCO As to storage disk usage. Generally, NSPM solutions need to first collect and store all the logs and make the necessary analysis afterwards. So, in a 10-firewall environment assuming 10K EPS log generation capacity the amaount of disk needed will be around 300TB per year. Making it more specific: Volume of data = Size of 1 syslog message x Number of messages per second x Number of seconds x Number of days x Compression Ratio Assuming we store the logs for 30 days and use a compression ratio of 5:1, we can calculate the volume of data as: Volume of data = 1 KB x 10,000 EPS x 1 second x 60 seconds x 60 minutes x 24 hours x 30 days / 5 Volume of data = 25,920,000 MB or 25,920 GB or 25.92 TB The cost coming from storage disk usage would be around 20K USD per year at minimum. What about effort usage? If the NSPM solution is not a user-friendly one and require good amount of work to maintain, it may need 0,5 to 1 human effort again for a 10-firewall environment. To maintain this kind of solution you may be needing one more employee if you have not planned it that way. To sum up, NSPM solutions may have hidden costs in place if you have not planned it that way. During the evaluation phase of any NSPM solution project one must take into account the TCO of NSPM if the solution requires the usage of firewall manager, if the system is storing all the logs and what may be needed effort to maintain that solution.
Challenges for an Effective Policy Change Management in Large Networks
Making policy management effective is not an easy task for large enterprise environments. There are several reasons for effective policy change management in large multi-vendor networks. The first reason is surely having a multi-vendor environment, the second issue is that the written materials are obsolete or missing. Apart from these the number of policies and firewall devices are too high. In this post we will deep dive on these issues and how to cope with them in detail. Generally, large enterprises especially operating globally have firewall devices belonging to different vendors and at least two or three vendors exist in their networks. The reason behind working with several different vendors may come from regulations, security politics, local needs or abilities and procurement strategies. It is a widespread choice and there may also other reasons however, we will not deal with these. This causes increasing the challenge for policy management. First of all, If you have different firewall vendors in your network you need to train your employees for each of them or need to hire new people to your team. Also, there will be no central management of this equipment. Each vendor has a different central management software. The cost and complexity of central management will increase if you are using central manager software. Finally, standardization may be a problem since different vendors have different capabilities and different approaches, so you may need to define more general use cases or policies that would be applicable for each vendor. To be more specific it is needed to have similar and lower number of vendors for this standardization. As to written materials and guidelines. Large enterprises may have several different documents or guidelines for their networks, servers, applications and databases. However, in most of the cases the written materials are obsolete. They are written when they are first installed or created and afterwards updates are not done for all of the materials. In that case, when a change needed the materials may not be sufficient to use. For example a new application server is to be installed for an already installed server farm. For this server to correctly work the security policies need to be applied. The application team may not open a ticket for the required policies since he or she does not know the necessities and there is no written material. In that case firewall admin will need to find the necessary policies to be applied, but it is not an easy task and requires a lot of effort. There will be similar other cases that will need effort, and this will increase the challenge for effective policy management. Lastly, for large environments the number of policies and devices is generally high. Any new policy to be applied may need to flow over at least two different firewalls. Also, since the number of policies is high examination or analysis of the firewall become more difficult. It may take weeks to analyze the policy tables on firewalls. To sum up, in large enterprises there are several reasons that increase the complexity and challenge for policy change management. It may be a good idea to use an easy to use and stable NSPM solution for an effective policy management in a large multi-vendor network.
