The vendor has signed agreements with Avnet Hall-Mark and Arrow Electronics' North American Computer Products group, under which most of its solution providers,about 100,will be required to work through the distributors.
Network Appliance's goals are twofold: Let the distributors take care of administrative details so Network Appliance can focus on its core business, and use the distributors to attract more solution providers, said Leonard Iventosch, vice president of channels at the vendor.
Arrow and Avnet have access to partners that Network Appliance would love to touch, Iventosch said. "They have partners in the midmarket, and that's where we want to be," he said. "Our direct team focuses on strategic customers. We are absolutely counting on our channel team to drive business in the midmarket."
Michael Fanelli, western regional manager at Sales Strategies, a Metuchen, N.J.-based Network Appliance partner, said where he buys Network Appliance products does not matter as long as he and his customers get the same sales and engineering support.
Sales Strategies can actually get better financing via the distributors than from the vendor, Fanelli said.
Network Appliance in the past two years has turned out to be a good partner, Fanelli said. "But it wasn't always so. Prior to that, it was on the same cycle as everybody else: partner-friendly one month, partner who? the next," he said.
Jeff Bawol, vice president and general manager of Avnet's Enterprise Software and Storage Business Unit, said Avnet will provide logistical support, lead-generation and other programs for solution providers.
Arrow plans to have Network Appliance equipment in its two storage labs by mid-August, said Mike Long, president and COO.
Potential attacks, software and platform vulnerabilities, malware, and misconfiguration issues can pose serious threats to organizations seeking to protect private, confidential, or proprietary data. Fortunately, various technologies – collectively known as unified threat management – make it easy to use virtualized or appliance-based tools to provide comprehensive security coverage.
With a combination of regular updates, monitoring and management services, and critical security research and intelligence data, you can vastly improve your business’s cybersecurity. We’ll explore how to erect defenses with UTM and implement sound security policies to cope with an array of threats.
What is unified threat management?
Unified threat management is an all-in-one security implementation that helps protect businesses from online security risks. A UTM solution includes features like network firewalls, antivirus software, intrusion detection and virtual private networks. Many businesses may prefer UTM software platforms, but hardware options, such as dedicated firewalls and router networking devices, are also available.
By implementing a UTM program throughout your organization, you provide a single security source for all of your information technology (IT) needs that can scale as your business grows.
With a UTM guarding your organization, you get a streamlined experience with various security components working together seamlessly, instead of the potential issues that could arise if you integrated multiple services for each function.
Why is unified threat management important?
By its very nature, technology is constantly changing. Unfortunately, this includes cybercrime; as technology progresses and we become more connected, the number of threats keeps growing.
This unpredictability is why it’s critical to implement a comprehensive UTM program throughout your organization. A UTM is like a cybersecurity force guarding against the most common vulnerabilities hackers could exploit. By essentially guarding every virtual entry point, a UTM is a great preventive security measure for any business.
Why is unified threat management necessary?
The history of information security and palliative technologies goes back to the 1980s, when perimeter security (through firewalls and screening routers) and malware protection (primarily in the form of early antivirus technologies) became available.
As threats evolved in sophistication and capability, other elements to secure business networks and systems became available. These solutions include email checks, file screening, phishing protection, and allow lists and block lists for IP addresses and URLs.
From the mid-’90s to the first decade of the 21st century, there was an incredible proliferation of point solutions to counter specific threat types, such as malware, IP-based attacks, distributed denial-of-service (DDoS) attacks, and rogue websites with drive-by downloads. This explosion led to an onslaught of data security software and hardware designed to counter individual threat classes.
Unfortunately, a collection of single-focus security systems lacks consistent and coherent coordination. There’s no way to detect and mitigate hybrid attacks that might start with a rogue URL embedded in a tweet or email message, continue with a drive-by download when that URL is accessed, and really get underway when a surreptitiously installed keylogger teams up with timed transmissions of captured data from a backdoor uploader.
Worse yet, many of these cyberattack applications are web-based and use standard HTTP port addresses, so higher-level content and activity screening is necessary to detect and counter unwanted influences.
What does a unified threat management solution include?
The basic premise of UTM is to create powerful, customized processing computer architectures that can handle, inspect, and (when necessary) block large amounts of network traffic at or near wire speeds. It must search this data for blacklisted IP addresses, inspect URLs for malware signatures, look for data leakage, and ensure all protocols, applications, and data are benign.
Typical UTM solutions usually bundle various functions, such as the following.
Modern UTM systems incorporate all these functions and more by combining fast special-purpose network circuitry with general-purpose computing facilities. The custom circuitry that exposes network traffic to detailed and painstaking analysis and intelligent handling does not slow down benign packets in transit. It can, however, remove suspicious or questionable packets from ongoing traffic flows, turning them over to scanners or filters.
The UTM agency can then perform complex or sophisticated analyses to recognize and foil attacks, filter out unwanted or malicious content, prevent data leakage, and ensure security policies apply to all network traffic.
Since many businesses are shifting employees to remote work models, it’s more critical than ever to invest in VPNs for data security.
Unified threat management providers
UTM solutions usually take the form of special-purpose network appliances that sit at the network boundary, straddling the links that connect internal networks to external networks via high-speed links to service providers or communication companies.
By design, UTM devices coordinate all aspects of a security policy, applying a consistent and coherent set of checks and balances to incoming and outgoing network traffic. Most UTM device manufacturers build their appliances to work with centralized, web-based management consoles. This lets network management companies install, configure and maintain UTM devices for their clients.
Alternatively, IT managers and centralized IT departments can take over this function. This approach ensures that the same checks, filters, controls, and policy enforcement apply to all UTM devices equally, avoiding the gaps that the integration of multiple disparate point solutions (discrete firewalls, email appliances, content filters, virus checkers, and so forth) can expose.
Top UTM providers
These are some of the most respected UTM providers:
Cyberthreat intelligence gives you a direct line into new and developing cyberattacks worldwide, so you can know the enemy and build an effective solution to prevent breaches.
How to choose the right UTM provider
When choosing a business UTM solution, you should seek the standard functions described above as well as these more advanced features:
Advanced UTM devices must also support flexible architectures whose firmware can be easily upgraded to incorporate new means of filtering and detection and to respond to the ever-changing threat landscape. UTM makers generally operate large, ongoing security teams that monitor, catalog, and respond to emerging threats as quickly as possible, providing warning and guidance to client organizations to avoid exposure to risks and threats.
Some of the best-known names in the computing industry offer UTM solutions to their customers, but not all offerings are equal. Look for solutions from reputable companies like Cisco, Netgear, SonicWall and Juniper Networks. You’re sure to find the right mix of features and controls to meet your security needs without breaking your budget.
IT InfoSec certifications that address UTM
As a visit to the periodic survey of information security certifications at TechTarget’s SearchSecurity confirms, more than 100 active and ongoing credentials are available in this broad field. However, not all of the best IT certifications address UTM directly or explicitly.
While no credential focuses exclusively on UTM, some of the best InfoSec and cybersecurity certifications cover UTM aspects in their test objectives or the associated standard body of knowledge that candidates must master:
Of these credentials, the generalist items (such as CISA, CISSP, and CHPP/CHPA) and the two SANS GIAC certifications (GCIH and GCWN) provide varying levels of coverage on the principles of DLP and the best practices for its application and use within the context of a well-defined security policy.
Out of the above list, the CISSP and CISA are the most advanced and demanding certs. The Cisco and Juniper credentials concentrate more on the details of specific platforms and systems from vendors of UTM solutions.
With the ever-increasing emphasis on and demand for cybersecurity, any of these certifications – or even entry-level cybersecurity certifications – can be a springboard to launch you into your next information security opportunity.

GRENOBLE, France – Dec. 7, 2023 – A team comprising CEA-Leti, CEA-List and two CNRS laboratories has published a paper in Nature Communications presenting what the authors said is the first complete memristor-based Bayesian neural network implementation for a real-world task — classifying types of arrhythmia recordings with precise aleatoric and epistemic uncertainty.
Considering medical-diagnosis and other safety-critical, sensory-processing applications that require accurate decisions based on a small amount of noisy input data, the study notes that while Bayesian neural networks excel at such tasks because they provide predictive uncertainty assessment, their probabilistic nature requires increased use of energy and computation. The increase is caused by the fact that implementing the networks in hardware requires a random number generator to store the probability distributions, i.e. synaptic weights.
“Our paper presents, for the first time, a complete hardware implementation of a Bayesian neural network utilizing the intrinsic variability of memristors to store these probability distributions,” said Elisa Vianello, CEA-Leti chief scientist and co-author of the paper, “Bringing Uncertainty Quantification to the Extreme-Edge with Memristor-Based Bayesian Neural Networks”. “We exploited the intrinsic variability of memristors to store these probability distributions, instead of using random number generators.”
A second major challenge was that performing inference in the team’s approach requires massive parallel multiply-and-accumulate (MAC) operations.
“These operations are power-hungry when carried out on CMOS-based ASICs and field-programmable gate arrays, due to the shuttling of data between processor and memory,” Vianello said. “In our solution, we use crossbars of memristors that naturally implement the multiplication between the input voltage and the probabilistic synaptic weight through Ohm’s law, and the accumulation through Kirchhoff’s current law, to significantly lower power consumption.”
Co-author Damien Querlioz, a scientist associated with the University of Paris-Saclay, the French National Center for Scientific Research (CNRS) and the Center of Nanosciences and Nanotechnologies, said the team also had to reconcile the nature of memristors, whose statistical effects adhere to the laws of device physics, with Bayesian neural networks, in which these effects can take arbitrary shapes.
“This work overcomes that challenge with a new training algorithm – variational inference augmented by a ‘technological loss’ – that accommodates device non-idealities during the learning phase,” he said. “Our approach enables the Bayesian neural network to be compatible with the imperfections of our memristors.”
Uncertainty quantification involves the network’s ability to identify unknown situations out-of-distributions.
If a traditional neural network trained to recognize cats and dogs is presented with an image of a giraffe, it “confidently misclassifies” it as a cat or a dog, Vianello said. “In contrast, a Bayesian neural network would respond, ‘I am not entirely sure what this is because I have never seen it.’ While this example is lighthearted, in critical environments like medical diagnosis, where incorrect predictions can have severe consequences, this uncertainty-capturing ability becomes crucial.”
This capability arises from the fact that synaptic values in Bayesian neural networks are not precise values, as in traditional neural networks, but rather probability distributions. Consequently, the output is also a probability distribution, providing information about its “certainty”.
Energy-efficient, smart appliances save money in the long run, but there are some exorbitant upfront costs. All told, purchasing and installing a full complement of kitchen appliances accounts for nearly 15%of the total remodeling budget, with an average price of $3,800.
The basic appliances that make up a kitchen include a dishwasher, oven, refrigerator and associated ventilation components. The good news? Replacing your appliances all at once allows you to match the aesthetic of the fixtures with the walls, countertops and cabinets. You also save some money by choosing a comprehensive package that includes all of the above appliances.
New ovens cost anywhere from $400 to $1,300, while new refrigerators cost $500 to $4,000, with certain custom models priced even higher. Finally, new dishwashers cost $300 to $1,200, depending on the size and features.
Cabinets represent the largest cost when remodeling a kitchen, even more than appliances. Installing new cabinets represents nearly 30%of the overall budget, with an average cost of $8,200, so plan accordingly.
Obviously, custom-made and handcrafted cabinets are the most expensive, so save money by buying stock or semi-custom fixtures. If you’re scared off by the exorbitant price tag here, you can also reface or refinish pre-existing cabinets and squeeze more life out of them.
Kitchen countertops are quite expensive to replace, accounting for 10%of the total project cost. Installing new countertops costs $1,200 to $7,780 when it comes to a full kitchen remodel. Of course, this depends on the type of counters you choose, the materials and, most of all, the size of the space.
Large kitchens have plenty of space for additional countertops, which increases the price, though allows more people to sit on a stool and eat breakfast at the same time. Save money by avoiding custom countertops made from expensive materials like marble: Go with stock or semi-custom counters instead.
Don’t ignore the flooring when remodeling the kitchen, as new flooring really helps tie everything together. All told, flooring accounts for around 7%of the total project cost, with an average cost of $4,200, though the real price depends on the type of flooring you choose and the size of the space.
Tile, laminate and linoleum are some of the more budget-friendly flooring options here, but you have many options, including the ones below.
Lighting and Electrical
It’s easy to overlook lighting when planning a kitchen remodel, or to blow all of your money on premium pieces that only add a bit of ambient light. The real stars of the kitchen lighting world are fixtures that illuminate not just the kitchen itself, but the food prep areas.
Lighting represents around 5%of the overall project cost, with an average price of $1,400. While this cost range does account for minor electrical work to install the new lights, it doesn’t account for major rewiring jobs. If you are completely overhauling the kitchen’s electrical system, that’ll drive the price up.
Installing a backsplash represents around 5% of the total project cost, with an average price of $1,400. The price varies depending on the materials used and the overall size of the kitchen counters. Complex patterns and unique designs drive this cost up.
A kitchen backsplash is basically an extension of your countertops. The purpose of these fixtures is to prevent water, grease and other icky substances from damaging your walls, particularly behind the stone and sink. Beyond that, installing a backsplash offers a chance to put another creative spin on the remodel.
Walls and Ceilings
Demolition is required when actually changing up the design of a space, like expanding the size of a kitchen. Demolishing an interior wall costs $400 to $13,000, and this price includes both the demolition itself and removing excess materials to the scrap yard. Generally speaking, load-bearing walls cost much more to break down than non-load-bearing walls.
If you just want to paint the walls in your kitchen, you could pay just around $100 or so to paint the walls yourself or up to $800 to have pros paint them for you.
Faucets and Plumbing
The humble kitchen sink and associated plumbing account for around 4%of the total project costs, with an average price of $1,000. If the layout of the kitchen remains unchanged, the cost tends to be on the lower side, as you don’t need to move the gas or water lines. Complete remodels that place the sink in an entirely new location drives the price up. The fixtures themselves aren’t that expensive, so the major price point here is whether or not you are rerouting pipes.
Labor accounts for anywhere from 18% to 25% of the total project cost, though this depends on the scope of the remodeling project. Full-scale remodels that require demolition and extension plumbing and electrical work require increased labor costs. The real labor price breaks down to $2,200 to $15,100. On the other hand, some aspects of a kitchen remodel are particularly DIY-friendly, like painting the walls.
