Hands-on network security

5 important tips for improving network security.
Repelling threats from malware.

How do companies and organizations better protect their IT networks?

It seems as inevitable as the proverbial death and taxes: Going hand-in-hand with the rapid increase in digitalization is an exponential growth in the number of attacks on IT systems, and thus on network security. Any security concept must take these dynamic developments into account and continuously adapt to the ongoing threat situation. Effective IT security uses the “onion principle” – attacks are intercepted by successive layers, each of which represents an increasing level of security.

5 important tips for improving network security

IT security aims to protect companies, organizations, and their data from being compromised or threatened. Its essence is to protect IT systems. And of course IT systems in need of protection include IT networks. We recommend five essential protective measures for your IT network to improve IT security and thus also network security:

1st

Use a Unified Threat Management (UTM) system as your central gateway. This kind of central all-round cybersecurity solution provides reliable protection of networks and data against undesirable content such as spam, viruses, or malware.

2nd

Segment your systems. By separating networks, unauthorized access to sensitive company data can be better restricted or limited in time.

3rd

In the wireless LAN you should ideally use the latest WPA3 security standard, but at least the WPA2 or WPA2 Enterprise (802.1X) security standards.

4th

Keep control over which software can operate on your operative devices. By managing your computers centrally you determine exactly which software your users can install by themselves, for example, or whether certain functions are reserved for authorized administrators only.

5th

Protect your IT systems by using network access control. Network access control (NAC) technology helps to defend against unauthorized access from the network, and helps to enforce end-device compliance with policy during authentication, e.g. whether the virus protection is up to date.

Additionally

Secure every single device against cyber attacks in the best possible way! Read here what you should pay attention to regarding your gateways, routers, switches, and access points and how you can increase the security awareness of all employees in your company.

Selecting the right firewall

When it comes to cyber protection, individualism is usually a good thing – both when it comes to passwords and choosing the best firewall for your business. The more precisely your firewall is aligned with your data volume, the number of connected devices, or typical traffic patterns, the better it can protect your network. With the Firewall Matchmaker from LANCOM, you can make this alignment in no time at all. With quick answers to just a few questions, you can find the tailor-fit firewall for your purposes immediately, without any lengthy pondering:

Securing devices against cyber attacks

Network security does not necessarily mean expensive new purchases. Your existing devices can also strengthen IT security in the company – and do so immediately!

In true hands-on fashion, you can check the device settings of your routers, gateways, firewalls, switches, and access points and increase their security right as you read this article, without waiting or incurring additional costs.

Cyber Security reimagined

„Cyberattacks are omnipresent and constitute a huge threat to the entire economy, regardless of size or industry. The rapid increase in mobile work and cloud services is also making companies even more vulnerable to cyberattacks. While greater flexibility is achieved through remote work and cloud services, the new structures, at the same time, create new attack vectors for cybercriminals which should sound the alarm bells with IT security experts.“  – techconsult study from 2022

Ensure network security – defense from malware threats

Secure connection types

We need IT networks wherever data is exchanged digitally. This may involve connections within a company, communication between different company sites, or the connection to a data center or cloud. Secure communication between different branches can be achieved centrally via VPN connections to a head office, or decentral via network security at each site.

 

VPN

VPN stands for virtual private network. A secure connection between different parts of the company is established via a data tunnel. Flexible approaches provide integrated network security at each site.

VPN is also well suited for secure connections to home offices. In this case, a software client on the company PC sets up a tunnel to a gateway on the company network, and this allows the transmission of data in encrypted form. Clientless VPN solutions are also on the advance.

ZTNA

The “Zero Trust Network Architecture (ZTNA)” is a new and forward-looking concept for secure communication between company departments and employees.

Access rights and the associated protective measures are centrally regulated by a ZTNA broker, which handles the fine-grained distribution of authorizations and security levels on a per-employee and per-service basis. In its final development stage, a ZTNA infrastructure makes traditional VPN clients unnecessary.

Security in black and white

No more beating around the bush! You're here to get serious about network security. So are we. That's why we have equipped a whole range of our routers with the IT Security Label of the German Federal Office for Information Security (BSI). By scanning a QR code, LANCOM customers can see exactly to what extent the respective products comply with the security requirements specified by the BSI and view all relevant IT security information – for conscious, clear, and informed purchasing decisions.
