Instead, the complexity and cost of managing different operating systems and tools increase. Using numerous devices which are separated and configured to carry out particular security functions won’t make the task easier. RELATED: Threat Detection and Response: Best Practices These dangers often have to be addressed with limited resources and budgets. Examples of such threats include viruses, spyware, Trojans and phishing. Information Technology workers have to frequently devise ways to shield and maintain digital assets and organizational productivity against sophisticated and constantly evolving threats. It consists of anti-spam, web filtering, anti-virus, and content filtering. UTM offers numerous security countermeasures for one network or device that defends users. How does Unified Threat Management (UTM) work? A single UTM appliance which can perform all crucial security tasks, supported by one vendor, IT team, and administered through a single console. Simplicity is the primary attraction of UTM devices. More advanced devices will also provide services such as network address translation (NAT), remote routing, and virtual private network (VPN) support. RELATED: Types of malware businesses must protect against UTM appliances will typically provide anti-virus, anti-spyware, and anti-spam protection, in addition to network firewalling, content filtering, leak prevention, and intrusion detection and prevention (IDP). Unified threat management (UTM), refers to a single security solution, which fulfills multiple security protection roles in a single device or service on the network. Traditional Security Solutions are no longer adequate.Why UTM is the Best Way to Mitigate Viruses.Benefits of Using United Threat Management.How does Unified Threat Management (UTM) work?.What is UTM (Unified Threat Management)?.HTTPS scanning is also conspicuous by its absence. It can only tag the subject line of suspect messages so you'll need rules for handling these either on your mail server or at each mail client. There are pros and cons here as no client configuration is necessary but for mail it can't perform quarantining. For the mail and web content filtering services, NetASQ uses transparent proxies. Web browser access isn't available as management is carried out by NetASQ's own Unified Manager, Realtime Monitor and Event Reporter utilities. As the appliance represents a single point of failure, HA is an essential feature and the U6000 supports active/passive configurations.įor deployment the U6000 can route traffic between selected network interfaces, function as a transparent bridge or use a combination of the two. ![]() ![]() The appliance can support up to 24 network interfaces and the wide range of spare expansion slots allows you to mix copper and fibre. Network connectivity options are extensive as along with two embedded Gigabit ports, the price also includes a quad-port Gigabit card. Power redundancy is also on the menu as the appliance is supplied with a pair of hot-plug supplies. The storage arrangement does look a little dated as the appliance comes with a pair of 73GB Seagate SCSI hard disks configured in a mirror. The hardware package for the U6000 is adequate as this 4U Supermicro rack system is equipped with a single 3GHz Xeon 5160 teamed up with 4GB of memory. ASQ is designed to reduce scanning overheads as it handles all firewall, NAT and VPN functions itself before passing it over to the mail and web proxies so reducing the number of processes required. Central to the appliance is the ASQ (advanced security qualification) engine which runs on a hardened FreeBSD kernel and uses three traffic inspection modes where it watches out for malicious content, employs behavioural and statistical analysis and uses twenty signature databases. The U6000 brings together NetASQ's firewall and IPS capabilities and serves them up with anti-virus, anti-spam and web content filtering services. Another bonus is NetASQ's licensing model as it provides support for unlimited users as standard. NetASQ aims to solve this with its latest U6000 which it claims as the first carrier grade UTM appliance with a maximum throughput of 5Gbps. A major concern for larger businesses is performance as a single appliance handling all security functions has the potential to become a bottleneck. ![]()
