I moved the internal traffic over to wan1/2, and I have broken apart the internal ports for various usages (connections to our ISPs, HA ports, etc). Further, the 110C only has 2 gig ports (the wan 1 and wan 2) and the 8 "internal" ports are all 10/100. With the services currently running on these boxes, we sit between 50-70% CPU, and can occasionally push more, and we have plans to grow by 50% or so over the next year or two. (Our internet is presently 18 and 15 megs, with plans to push both to 25-30 soon). (almost all traffic is to/from the internet, there is not much (on the order of 50Mb/s total) beyond this for all the seats/servers.) To reduce the load on internet paths, I'm trying to push for local server replication.
This could ultimately lead to a performance issue as well, meaning that the performance of the network may slow down, but is not to be a problem that cannot be overcome.I currently have a pair of 110C's in HA mode, that, due to the size of our office and the internal separation we have to maintain these boxes also act as the internal router/firewall/dhcp device. This risk should be taken seriously and weighed against the possible benefits of a UTM when analyzing security solutions. Companies using a UTM device take the risk of putting all of their security ‘eggs’ in one basket. This means that any malicious or ignorant entity would only have to disrupt the UTM to bring down the entire security system.
When a company’s security capabilities are concentrated in one appliance, it becomes a possible single point of failure. The main benefit of using a UTM solution can also be its greatest weakness. Challenges of Using a Unified Threat Management Solution Because it is a single point of defense, UTM’s make dealing with combined threats easier. This is because each security wall has to be managed individually in order to remain up-to-date with the changing security threats. When using separate appliances for each security wall, preventing these combined attacks can be difficult. These threats consist of different types of malware and attacks that target separate parts of the network simultaneously. UTM solutions also help to protect networks against combined threats. Appliances that use identity-based security to report on user activity while enabling policy creation based on user identity meet the requirements of regulatory compliance such as HIPPA, CIPA, and GLBA that require access controls and auditing that meet control data leakage. Some UTM solutions provide additional benefits for companies in strictly regulated industries. This can also save money in the long run as opposed to having to buy multiple devices. Similarly, having one program that controls security reduces the amount of training that employees receive when being hired or migrating to a new system and allows for easy management in the future. Because the capabilities of multiple specialized programs are contained in a single appliance, UTMs reduce the complexity of a company’s security system. UTM solutions offer unique benefits to small and medium businesses that are looking to enhance their security programs. Benefits of Using a Unified Threat Management Solution It is important to keep in mind that each solution is used for different reasons and none is superior to any other.
UTM devices offer seven layers of security, NGFW being one of those layers. They were originally designed to fill the security hole left by traditional firewalls. NGFWs are firewalls that include intrusion prevention systems and application intelligence. However, UTMs include additional security features such as gateway antivirus and content filtering that are not covered by NGFWs. It is true that some capabilities of NGFWs overlap with those of UTMs. Some sources say that UTMs and next-generation firewalls (NGFWs) are synonymous. Some applications may also include additional features in order to appeal to certain customers. Features of UTM SolutionsĪlmost every unified threat management application includes the same seven features. UTMs are commonly used in branch offices, home offices, banking, retail, and midsize companies. This is most popular among small businesses because it provides an affordable alternative to purchasing each security solution separately. The all-in-one solution is much easier for an organization to manage than several different security solutions, reducing the complexity. Unified threat management (UTM) describes network solutions that integrates the capabilities of several security products into one all-inclusive security console.
