The Critical Role of the Security Edge Protection Proxy

With each passing year, networking technology changes at a rapid pace. The latest introduction, 5th generation networks, has ushered a new era of wireless communication ensuring maximum speed, connectivity, and efficiency for users.

Alas, with such a complex system, there are bound to be certain difficulties. Perhaps the biggest risk comes in the form of potential security threats. The tech creates numerous openings that attackers can exploit to extract valuable information and conduct other devious plans.

Luckily, we can protect ourselves from most of these issues with security edge protection proxy and similar systems.

What is the Security Edge Protection Proxy?

Security Edge Protection Proxy, or simply SEPP, has become an integral part of 5G networks. As the name implies, we primarily use it as a defensive measure to stave off external intrusions. With it, we create a secure environment where data can be transferred between devices and networks.

The best thing about SEPP is that it ensures the full integrity of data. All your information remains confidential and is not exposed to external factors. As a result, it can travel safely from its original source to the end network.

Specifically, SEPP performs the following functions:

  • Allows secure signaling between public land mobile networks
  • Allows networks to share data while authenticating it between different systems
  • Functions as a reverse proxy, giving all network functions a single point of entry
  • Provides filters for network traffic, as well as overload protection and policing
  • Ensures topology hiding between different public land mobile networks

With SEPP technology, networks gain full protection against various threats. These proxies rely on versatile authentication to ensure unauthorized people can’t gain any access. By relying on advanced algorithms, they stay ahead of the curve, protecting 5G networks from any potential threat.

In fact, we’ll go as far as to say that SEPP has become a security standard for 5G.

Common 5G Network Challenges

To better understand SEPPs and their importance, you have to understand the challenges 5G networks face. These issues become even more noticeable nowadays, given the sheer number of IoT devices we use in our homes and offices.

  • Data Security Treats

One of the main features of 5G networks is their ability to tackle large quantities of data. While this is fantastic for users, it also puts any network at a massive risk. With so many endpoints to think of, the data quantity progressively increases over time. As the processes and usage scales, so do the threats that come with it.

  • Increased Data Surface

To piggyback on that, we have to think about an enormous surface that security software has to defend. With each new IoT device, smartphone, or similar device, there are more entry points.

However, the issue doesn’t only relate to devices; we also have to think about numerous apps, each of which serves as a potential gateway for intruders. Some of the main challenges providers have to think of include data manipulation, spoofing, and eavesdropping.

  • IoT Device Security

Speaking of IoT devices, they can quickly become a major liability for any type of network. Some of them lack advanced encryption and other protection measures, which is why it’s so easy for attackers to access them. By gaining access to these devices, attackers also gain access to the networks as a whole, allowing them to wreak havoc all over the place.

Another major issue with IoT devices is that they don’t have the same firmware security as some other types of devices. Their software isn’t patched as often as software on some other devices, making them inflexible to newer threats.

  • Location Tracking

Another major issue 5G providers have is location tracking. While governments are doing their best to increase their coverage, they still aren’t as widespread as 4G networks. To make matters worse, the signals from 5G networks have a hard time penetrating through thick objects and buildings.

As a result, you need more infrastructure to support them. It also means that it’s easier to locate users based on their current whereabouts. Given there are fewer stations people are connected to, making a positive ID isn’t that hard. So, location tracking poses a major security risk for users.

  • Issues With Compatibility

Right now, new 5G networks are heavily relying on old infrastructure to provide users with premium experience. Unfortunately, as these are significantly different systems, attackers are able to exploit their vulnerabilities. They can tap into both new and old networks and take advantage of their compatibility.

Issues with backward compatibility and operational problems can further endanger 5G systems and all devices connected to them. This is one of those problems that will likely vanish with time as we switch to newer infrastructure, but for now, it is a major issue.

The Role of Security Edge Protection Proxy

The sheer diversity of modern devices and infrastructure causes providers all sorts of headaches. With so many endpoints to consider, the attack can come seemingly from anywhere. Administrators have to invest enormous resources in tracking all these potential issues and patching them as soon as there’s a solution.

By relying on SEPP, providers ensure secure data transfers. They use proxies to establish connections between visited and home networks by centralizing their 5G security protocols. Not only does the implementation of SEPP help provide higher efficiency, but it also sets the basis for monitoring and improvement.

With the power of proxies, we’re able to encrypt all signaling data transferred within the network. It allows you to send and receive information across various devices. SEPP is integral for internetwork communication, introducing joint standards for data exchange. All of this has a positive impact on traffic management while making it easier to detect external threats.

Last Thoughts

Security edge protection proxy is vital for increasing protection, data integrity, and overall confidentiality of users. It’s a vital piece of the puzzle for any 5G provider who wants to ensure higher quality of service. Although SEPP can’t address each challenge mention in this article, it still moves the needle for your network security.
