People who studied network security or worked as IT professionals two or three decades ago would struggle to cope with today’s modern corporate network. There are so many new technologies, best practices, and acronyms that it’s hard to keep up. For example, containers, cloud computing, and bring your own device (BYOD) policies were virtually unheard of a few years ago, but are now commonplace in many organizations.
Network security and management is a complex and constantly evolving field. To stay ahead of the latest threats, you need to know the latest trends and acronyms. Here are some of the most important network security trends and acronyms.
What is Network Security?
Network security can be defined as the practice of protecting networked systems, including hardware, software, and data, from unauthorized access or theft. It includes configurations and rules to protect against attacks and physical security measures to deter and detect intruders.
Network security is essential because it helps protect sensitive information from unauthorized people. It also helps prevent Denial of Service (DoS) attacks, rendering a system unusable.
In today’s connected world, where technologies such as 5G and the Internet of Things (IoT) are becoming more prevalent, network security is more important than ever. Network administrators face an ever-changing and sophisticated threat environment where cybercriminals are always on the lookout for vulnerabilities to exploit.
According to a Barracuda report dubbed The State of Network Security 2021, 81% of respondents said their organization had experienced at least one security breach in the past year, while 74% of respondents said their company had suffered at least one ransomware attack. Last year.
And network attacks are no longer perpetrated by single individuals or teams of a few today. Instead, attacks are now carried out by governments, by companies against competitors, and by large transnational criminal networks.
Network administrators need to be aware of the latest threats and take appropriate steps to protect their systems.
Network Security Trends
Several network security trends are making headlines. Here are some of the most recent developments in network security management.
Zero Trust Security Model
The Zero Trust security model is a security concept that advocates a “zero trust” approach to security in which organizations do not automatically trust any individual or entity, device or application on the network. This is essentially a “presuming a breach” mentality in recognition of the collapse of the traditional security perimeter.
The Zero Trust model was first coined by Forrester Research in 2010 and has grown in popularity in recent years as more organizations migrate to cloud and hybrid environments. Some of the world’s largest technology companies, such as Google, IBM, Oracle, Microsoft, and even the US government, have embraced the Zero Trust security model.
Under the Zero Trust model, all network users, devices, and applications are untrusted until they can be authenticated and authorized. Network administrators carefully assess all risks before granting access to users, devices or applications.
Cybersecurity education and knowledge sharing
According to a joint study by Stanford University and security firm Tessian, nearly 90% of all data breaches are caused by human error. It would therefore be reasonable to assume that one of the best ways to combat data breaches is to educate employees on cybersecurity best practices.
Organizations are beginning to realize the importance of training their employees in cybersecurity. As a result, many organizations are now making cybersecurity training a requirement for all employees. The goal is to educate employees on how to identify threats and prevent attacks and change the culture of the organization, so that cybersecurity is a priority for everyone.
A focus on incident detection and response (IDR)
Organizations are now placing more emphasis on incident detection and response (IDR). IDR is about detecting security incidents as they happen and then reacting in a way that minimizes the damage.
IDR requires a proactive approach to security where organizations are constantly on the lookout for suspicious activity. Once an incident is detected, it is important to have a plan to carry out the appropriate response quickly and efficiently.
AI for network security
Artificial intelligence (AI) is increasingly used in network security as it can be used for tasks such as identifying malicious traffic, detecting malware, and analyzing data. AI also offers many benefits for network security. For example, AI systems are trained to generate threat alerts, identify new types of malware, and protect sensitive data.
Several companies offer AI-powered network security tools, including some of the best-known vendors like Cisco, CrowdStrike, and Fortinet.

Combine NetOps with SecOps
NetOps and SecOps are two disciplines that are often siloed in most organizations. However, there is a growing trend for organizations to combine the two disciplines into one team.
NetOps is the practice of managing and operating a network. SecOps is the practice of securing a network. By combining the two disciplines into one team, organizations can create a more holistic approach to network security.
Moving to Hybrid Environments
More and more organizations are migrating to hybrid environments, which involve a mix of on-premises and cloud-based infrastructures. The benefits of a hybrid environment include increased flexibility, scalability, and cost savings. However, it is important to note that hybrid environments have their own set of security challenges.
For example, data in a hybrid environment is often distributed across multiple platforms, making it more difficult to secure. Additionally, hybrid environments are often more complicated, leading to increased complexity in the network security stack.
Consequently, the trend is towards a more consolidated and security-focused view of an application’s performance. This approach requires tools that provide visibility into different environments. It also requires combining cloud-based and traditional network-based monitoring methods.

4 Popular Network Security Acronyms
Below are four of the most popular network security acronyms.
BYOD: Bring your own device
BYOD is the workplace practice that allows employees to bring their own devices (such as laptops, smartphones, and tablets) to work and use them for business purposes.
BYOD can pose a security risk because it increases the number of devices connected to the network and increases the threat surface. Additionally, many employees are unaware of the risks associated with using personal devices for work purposes.
To address this risk, organizations often develop BYOD policies that outline the rules and guidelines for using personal devices at work. Employees who wish to join an organization’s BYOD program must agree to the terms of the policy.
ZTN: Zero Trust Network
A Zero Trust network operates according to the Zero Trust security model described above. This means that each device and user must be authenticated and authorized before being granted access to resources.
SASE: secure access to the service edge
The Secure Access Service Edge (SASE) is a category of enterprise networking introduced by Gartner in 2019. SASE provides organizations with a way to securely connect users to applications and data regardless of location.
Previously, administrators implemented network access with siled point solutions, which was complex and expensive. This approach has hampered IT agility.
SASE enables companies to shorten the development and delivery of new products and react quickly to changes in the business environment.
XDR: Extended Detection and Response
Extended Detection and Response (XDR) is a security solution that provides visibility into all aspects of an organization’s IT environment. XDR solutions are designed to detect, investigate and respond to threats across the entire attack surface.
With new threats and vulnerabilities emerging every day, it can be difficult to keep up with all the latest trends and acronyms. Corporate network administrators must remain vigilant and regularly informed of the latest trends and developments to maintain a secure network.
