Campus network design best practices,Author: Katie McNeil,By 2025, students entering college campuses will be mobile natives—that is, born after the . The modern learning experience takes advantage of technology such as and . These not only provide immersive learning opportunities but can also help expand how programs can be delivered. The importance of campus network design,However, new technologies may only have a limited impact if the network infrastructure isn't properly designed to handle modern higher education network and security requirements. Pandemic remote learning to the limit. Institutions are more dependent on tech than ever, but tightening budgets can limit their capacity to modernize. Supporting the digital backbone of a modern campus takes resources and skills that might be in short supply. For example, the median IT department is $1,316 according to Educause. In one survey of university IT professionals, and universities during the 2020-21 school year and the median IT budget decrease was 10%. Recent years have shown the value of having a and evolve to meet the ongoing needs of students and staff. A smart campus network can strategically leverage new technology and robust network infrastructure to enhance collaboration, provide meaningful learning experiences and enhance campus safety. Campus network design best practices,There's no one-size-fits-all campus network design, but the following best practices can help ensure your campus is smart, fast and secure. Segmented networks,Colleges serve a staggering number of user endpoints. One university estimated it had , while a separate report by Educause found . To address the need for security and efficiency, university IT departments should consider a segmented campus network design. Segmented networks run on the same physical infrastructure but are logically separated by using logical or physical switches at the network edge. These switches allow the campus IT department to separate devices into virtual local area networks (VLANs) by the type of user—student, staff, faculty or guest. Connect with campus area networks,Many university IT departments connect students, faculty and staff to the internet with a (CAN). These networks cover a limited geographical area (in contrast to metropolitan or wide area networks) and connect buildings and departments by connecting multiple local area networks (LAN). Because all data is self-contained within the network, users experience minimal latency when accessing content. Distributed networks for minimal latency,For uninterrupted learning, the campus network design should be distributed for minimal latency. In addition to using a CAN for interdepartmental connection, —infrastructure near end-user locations—minimizes the distance data needs to travel and reduces latency. Another way to minimize latency is using a content delivery network (CDN) placed in strategic locations close to end users and their devices. Content is cached in CDNs so that data packets don't need to travel from the original server. This is best for content that is delivered to many end users, as expected with streaming media applications. Provision of bandwidth on demand,Remotely configuring higher bandwidth can help university IT departments stay nimble as needs change. For example, if a department requires a high-speed connection for a data-intensive research project, that network segment can be virtually deprovisioned when the project ends. With the right core fiber networks and software to control resources, what used to take months to deploy can now take minutes. Ensure your university IT department budget assumes increasing bandwidth needs. The Federal Communications Commission estimates over the next four years. The role of security in university IT,Of the top 10 issues facing college IT departments, . What offers students and faculty more flexibility—hybrid learning on multiple devices—offers cyber criminals multiple openings to infiltrate. The Verizon 2022 Data Breach Investigations Report found the education sector . The report notes external actors with financial motives are largely responsible. Enhance your cyber security,Mitigating your security risks means strengthening, securing and modernizing your network infrastructure. When considering your campus network design, some elements to consider include, for example, the enhanced security benefits of (VLANs). Firewalls can limit traffic flow between VLANs of differing security levels. Three layers of firewalls—perimeter, network and host—can ensure separation and high security between subnetworks. Endpoint security,can mitigate endpoint risk by streamlining how you manage mobility and protect data using a single management portal. IT administrators should require personal devices to register on these solutions to access the network. Restricted data on mobile devices—whether campus-owned or personal— should be encrypted using approved encryption techniques and password protected. should be registered to allow university IT staff to lock or wipe data if the device is lost or stolen. Benefitting from the cloud,From students' personal information to sensitive research study data, universities generate and store a staggering amount of data, much of it sensitive. allows universities to store data on the internet rather than bulky on-site servers and to scale operations and rent processing power without the need for infrastructure on standby. The pandemic reinforced the benefit of the cloud. Universities that embraced cloud computing pre-pandemic had a much . The cost savings (both resources, time and money) and ability to scale operations quickly make cloud computing an efficient solution for budget-conscious university IT departments.

What does a firewall do, and does my business still need one?,Author: Sue Poremba,Firewalls have been the default cyber security tool for many years. Even today for many companies, their firewall and their endpoint anti-malware remain their primary or only IT security. Despite security tools becoming increasingly sophisticated, firewalls remain popular, with the global firewall market to reach $8.6 billion by 2026. Yet small business owners, already facing rising costs amid a global pandemic, may have questions about the value of firewalls as a service. What does a firewall do and is a firewall really necessary? Before answering the crucial question "what is a firewall in a computer network?" it is important to consider the cost of cyber attacks on small businesses. The impact of cyber crime on small businesses,The notes the cost of cyber crimes reached $4.2 billion in 2020, and while the Small Business Administration (SBA) cyber attacks are a growing threat for small businesses, Intrusion, Inc. projects that annually by 2025. According to the , 71% of cyber attacks occur at businesses with less than 100 employees and the average cyber attack costs a small business an average of $34,604. It takes an average of 191 days for a small business to become aware of a cyber attack, and nearly 60% of companies go out of business within six months of a cyber attack. The SBA says small businesses are attractive targets because they have information valuable to cyber criminals, without generally having the security infrastructure or access to the required resources of larger businesses. A recent SBA survey found 88% of small business owners felt their business was vulnerable to a cyber attack. Yet many businesses have few, if any, skilled resources, limited knowledge of appropriate tools, minimal time to devote to cyber security, or simply don't know how vulnerable they really are. What does a firewall do?,So, what does a firewall actually do? The goal of is to protect your network from unauthorized access. A firewall monitors both incoming and outgoing network traffic, allowing only permitted packets to get through. The firewall helps prevent intruders from accessing your systems when you are online as people with malicious intent can invade your computer to delete or corrupt files on your system, hunt down personal information stored on your computer, or even read your email. A firewall may be one of the more well-known cyber security tools, but how it works has changed as the technology and the attack vectors has become more sophisticated. This is why it is important to understand not only what a firewall does, but also how a firewall fits in an overall computer network architecture and how a firewall can be a part of a solution. How does a firewall fit a computer network?,A firewall can be a piece of hardware (often called a security appliance) with specialized software installed on it, or it can be simply an application installed on a system, or it can be a virtualized system deployed in a cloud. Some organizations may find that they need a combination of firewall type services. A hardware firewall is a device that is installed at the edge of a company's network, acting as a barrier between the organization's internal networks and its internet connections. A software firewall is typically installed on each individual device and can offer protection down to individual applications. A cloud based firewall can allow companies to central the firewall and security functions and reduce overhead. Within those offerings, these are the most common types of firewalls:,Safeguarding your network, data and business,While firewalls in some form or another have been around since the 1990s, firewalls remain a crucial element of modern cyber security. Here are a few reasons why:,Firewalls as a Service and SASE,SASE takes firewall and other security functions to the next level. Combining wide-area networking () with to help provide more efficient and better performing secure network services to distributed WANs. Think of SASE as essentially a firewall as a service, and like other cloud offerings, it can provide a scalable, affordable solution wherever it is needed. Through a managed service provider, SASE can reduce IT complexity and cost, reduce risk, and improve application performance and user experience. Given the threats of cyber crime to small businesses, it's important to have an understanding of what a firewall does and what a firewall is in a computer network. However, with limited time, expertise, and resources, it can make sense for small business owners to make the most of managed security services from a trusted provider.
