Gallery-worthy prints at home: Photo printer
The Epson SureColor P600 is capable of delivering gallery-quality prints up to 13 inches wide, and can print panoramas up to 10 feet long. It can also print on a huge variety of media, including metal and CDs.
Though its colour photos caught our eye while testing for the best photo printer, we especially loved the black-and-white output; it’s as close as you can get to traditional darkroom prints at home. Those prints will last you a long time, too: the P600’s UltraChrome HD pigment ink is one of the longest-lasting consumer inks.
The touchscreen interface is a cut above what you’d get from most rivals. Ink costs are reasonable, and you can get extra-large-capacity tanks, so you’ll need to fill up less often. In addition to Wi-Fi, this printer has USB and Ethernet connections for faster printing.

Types of Engineers
Engineering is similar to the medical field in the sense that you don’t just simply choose to be an "engineer,†just like you don’t simply choose to be a "doctor.†You have to pick a specialty, as there are many different types of engineering jobs.
In this guide, we’ll be comparing and contrasting the different aspects of the different types of engineering careers, including:
Job responsibilities
Educational requirements
Salaries (pulled from the Bureau of Labor Statistics)
Pros and cons
How to get your foot in the door.
An electrical engineer’s job will typically involve designing an electrical system or electrical equipment.
Electrical or electronics engineers work with computers, cell phones, and basically any device or item that transmits energy. The daily responsibilities of an electrical engineer could include testing an electrical system, solving any problem that comes up, designing a system or piece of equipment, checking a system or piece of equipment for safety, and much more.
Electrical Engineering: Pros and Cons
For one, the pay for electrical engineers is definitely attractive.
Also, electrical engineering is a fairly flexible job. There are various industries that you could apply your skills in. Unlike software engineering, you may get to use your hands more and get out of the office every once in a while.
That’s not to say that you won’t spend time at a computer. Electrical engineers use programs to design and map out systems and equipment.
Also, a con of electrical engineering is the inherent dangers involved with working with electricity.

Five Ways to Reinforce Your SD-WAN Security
SD-WAN technology offers numerous benefits, such as greater agility and lower transport cost. But how do you address security once you move traffic off a structured, private MPLS VPN and onto public broadband links?
Here are five tips to ensure that your SD-WAN will always be resilient and secure.
1. Integrate SD-WAN security into your organization's overall security architecture
Many enterprises make the mistake of treating SD-WAN security separately rather than as a key element in their overall enterprise security strategy."Most organizations look at SD-WAN as a connectivity tool that provides a level of data encryption," observed Amit Bareket, CEO of network security technologyproviderPerimeter 81. "However, SD-WAN solutions commonly don’t protect the security of the data, which exposes your organization to security risk."
To lock down SD-WAN traffic, organizations, and their security teams should develop an approach that integrates policy-based control rules that are designed to monitor data traffic with a holistic SDN managed detection response model, Bareket advised."By putting security first, it provides another layer in the fight against holes in your organization’s network," he noted.
2. Don't view your SD-WAN as a traditional network technology
It's a mistake to view SD-WAN security in the same context as a traditional physical network, which automatically places certain constraints on data flow that don't apply to SD-WANs."For example, with a traditional network, you have to consider the traffic patterns and bandwidth requirements," explainedKowsik Guruswamy, CTO of cybersecurity firm Menlo Security."This will determine where and how you enforce your security policies." But with an SD-WAN, the Internet is the network, so the constraints that apply to traditional networks simply don't exist.

3. Don't tie security to a single vendor
An enterprise’s security needs evolve over time as the network infrastructure expands and new threats arrive. Having the flexibility to migrate to alternative security solutions quickly and cost-effectively as attack vectors appear while retaining the basic SD-WAN investment, is a valuable ability. Unfortunately, some SD-WAN vendors effectively lock-in customers to a single proprietary security stack."As a result, [they] don’t offer flexibility for the future, nor the flexibility to work with an existing [enterprise] security infrastructure," noted Karl Brown, senior director of VMware's VeloCloud business unit.
4. Don't rely on legacy firewalls
With traditional WANs, branch traffic is either backhauled to the enterprise data center, where it may be processed by a legacy firewall, or there may be a legacy firewall deployed at the branch that's maintained separately from the edge router."This can lead to several issues, such as expensive bandwidth, heavy performance penalties, unpredictable application performance, and unnecessarily complex branch IT management,"Brown said."With SD-WAN, enterprises can more efficiently hand off traffic to cloud and SaaS tools via cheaper Internet access services or utilize cloud-hosted gateways that peer with cloud and SaaSproviders."
However, when deploying SD-WAN access at branch locations, enterprises must take additional security precautions, since connecting to the Internet creates a broader attack surface."The best approach to mitigate this new security risk is to leverage the power of the cloud for threat detection and mitigation," Brown advised. He also suggested adopting a unified management approach, incorporating templatized policies and auditing, and integrating networking and security at each branch."Taken together, an enterprise can efficiently implement and maintain a consistent advanced threat management strategy," he noted.
5. Properly position the SD-WAN appliance
Many SD-WAN adopters accidentally bypass their firewalls, either by deploying the SD-WAN appliance behind the firewall or bypassing the firewall while troubleshooting and/or configuring the SD-WAN box, explained Brendan Patterson, vice president of product management at network security firm WatchGuard Technologies."In this scenario, the organization has no security at all, which puts them at a high risk of malware infection," he observed.

Evolving Enterprise Security with SD-WAN
One of the hottest enterprise networking services is SD-WAN. In its first iteration, it was adopted by many enterprises for branch connectivity, especially where IP-MPLS leased line services were scarce or too expensive. It continued to evolve as enterprises embraced the cloud and SaaS. SD-WAN is increasingly used to connect public and hybrid cloud services to the enterprise network and support multi-edge computing and mobility. A crucial
impact of SD-WAN is the changing needs for security in this more distributed, open relationship between the LAN, WAN, and cloud.
Traditionally, branch offices connected to the open Internet and public clouds by passing through the enterprise network to one or more centralized, controlled Internet access points. Trying to protect every branch office, each with its own vulnerabilities, consistently, is complicated and expensive. With SD-WAN, public cloud, and SaaS, there’s a growing need for branches to directly "break out†to the Internet to access business applications.
As it turns out, distributing the centralized, one-gate, one-drawbridge approach to security is relatively straightforward in an SDN. SD-WAN can distribute central security functions to any endpoint with relative ease using policies. Just as early-day SD-WAN virtualized the branch connection over any kind of transport, the next-generation can use that same platform to implement virtualized network functions (VNFs), such as firewalls and NACs, with greater awareness of local user behavior.

Deploying the Cato SASE platform
Cato makes it quite easy to implement SASE, thanks to a well-thought-out deployment process. For most installations, it takes little more than installing and connecting the Socket SD-WAN device to the internet. Configuration is done via the Cato’s central management console, which offers ample help, as well as recommended settings. The Cato Sockets are "internet aware,†meaning that as soon as the device is plugged into a viable internet connection, the device will automatically download the latest firmware, further easing the initial deployment. Once the socket is associated with a site, it will also automatically pull down the enterprise’s configuration and rule sets. Adding branch offices can be accomplished in a matter of minutes.
Those deploying the Socket
SD-WAN Device do need to be aware of their connectivity options, and for most deployments, there are usually multiple connectivity paths used for failover and or load balancing. In many cases, those adopting the Cato SASE Platform are also looking to depreciate and retire MPLS connections or other legacy technologies. That means it is critical that the selected replacement is up and running before making that switch over.
However, Cato does not force deployers to immediately switch over to new connectivity providers. The platform supports hybrid WAN configurations where legacy connections (typically MPLS) run those in parallel with new connections to the internet. This allows network managers to transition away from MPLS circuits at their own pace or retain them for business continuity purposes.
Those supporting mobile or remote users will find adding users to the Cato Cloud simple as well. Remote users can choose to connect using the Cato client application or connect with a browser. Of course, support personnel can simply email the client file and guide remote staffers through the initial setup process or automate it completely if an ITSM/RMM solution is in place.

SERVICE LEVEL AGREEMENTS
SERVICE LEVEL AGREEMENTS
One of the things that has come up recently in conversation with potential clients is service level agreements or SLAs. Not everyone is familiar with that term, so I’ll give you a quick definition from Wikipedia.
SLA Definition
A service-level agreement (SLA) is a commitment between a service provider and a client. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. The most common component of an SLA is that the services should be provided to the customer as agreed upon in the contract. As an example, Internet service providers and telcos will commonly include service level agreements within the terms of their contracts with customers to define the level(s) of service being sold in plain language terms.
Applications to IT Services
So why has this been coming up in discussion with potential clients? Well, it’s because i.t.NOW has an SLA on its services. That’s right. We guarantee our clients that we will respond to their issues within a certain amount of time based on the severity and the impact of the issue.
Most of our competition doesn’t do anything of the sort. In fact, most IT providers and even managed services providers (which is supposed to indicate a higher level of service) don’t even track their response times.
How could they possibly offer you a service guarantee on something they don’t even track? The short answer is that they can’t.

Enterprise Service Management with Jira Service Desk and Confluence
Enterprise Services Management (ESM) is a popular approach to implementing services within the organization. Departments such as human resources (HR), operations and marketing are seeing the value of Information Technology Service Management (ITSM) processes, and companies are looking to repeat that same value across the business. ESM allows all departments in the organization the opportunity to standardize tools and processes across all of their services departments. This standardization of tools and processes can create transparency, can improve the customer experience and in the end can reduce overall cost.
There are quite few tools that can be used to support the implementation of ESM. Two components of an effective ESM implementation include a shared service desk and a knowledge base.
The shared service desk encourages the standardization of tools, and even paves the way for the alignment of processes. Departments should find tools that can be scaled up from just ITSM to support requirements across different service departments. There are quite a few applications available to companies for a shared
service desk.
In order to promote adoption, organizations must consider the ease of usability for both customers and customer service providers. Atlassian has two applications, Jira Service Desk (JSD) and Confluence, that together provide companies their shared service desk and knowledge base components of their ESM solution.
JSD can be used as the foundation of an organization’s ESM implementation. Having JSD as the standardized service desk provides customers with a single customizable portal for all requests across the business. Unlike Jira Software and Jira Core, JSD licensed users are called agents. Companies only pay for agent licenses and do not pay for their customers.

What is a DDoS attack?
A conventional denial of service attack relies on using one internet-connected device to saturate a target server’s bandwidth and render a website unusable.
A DDoS attack is very similar to a DoS attack, except instead of relying on one device it uses multiple (hundreds or even thousands) of internet-connected devices distributed around the world to carry out the attack. These devices typically take the form of a botnet (otherwise known as a zombie army), a group of machines that have been infected with a type of malware which grants the hacker the ability to control the compromised machines remotely. The distributed nature of a DDoS attack makes it difficult to stop as there are simply too many sources to block.
While there are a few different types of DDoS attacks (more on that later), they all share a similar goal: disrupting the operations of a specific website and making it inaccessible or dysfunctional to regular users.
