With the inception of next-gen technologies such as the Internet of Things (IoT) and Big Data, the network security landscape has become more complex and vulnerable in recent times. As a result, there has been an ever-increasing jump in the number of internet security threats.
This includes malicious malware, attacks focused on IoT devices and closed networks, phishing attacks, among many others.
Over time, attackers have evolved to become more technologically informed and have resorted to new and advanced methods of planned attacks on internet security components.
While network security is a challenge that we will continue to face, there are some very effective measures that can help individuals and organizations keep up with changing technologies and the subsequent network security threats that we might encounter.
Key Measures to Secure Internet Network
Once you identify how your network works and reacts to threats, it becomes easier for you to identify any potential risk in the form of anomalies. A network Anomaly Detection Engine (ADE) enables users to analyze and understand the behavior of their network. This helps in coming up with quick mitigation strategies to avoid any loss of confidential data. Hence, businesses should be looking to implement ADE in their security solution.
It is a known fact that if your network is secured, there are critically fewer chances of your network getting breached by unauthorized personnel. However, at times, even authorized personnel can cause potential threats to the system.
To avoid such network security breaches, the Access Control methodology enables users to secure networks by limiting the access rights of authorized users. Basically, it allocates resources and accesses to individual users strictly based on their responsibilities and, thus, limits the chances of any potential security threats to the network.
Next-Gen Virtual Private Network Security
Virtual Private Network remains one of the most effective ways of ensuring network security. VPN transfers data in the form of data packets which consists of encrypted data coupled with a header. This header consists of separate routing information.
This coupling of encrypted data and routing information results in the creation of secure data packets that can be delivered over a public/shared network. These data packets cannot be read without the decryption keys, which makes the transmission of data secure.
One of the primary benefits of using a VPN for network security is the fact that users can connect and transmit data over networks, both from their home networks and while they are on the go. This functionality of VPNs help improve Wi-Fi security as well.
Another great benefit of securing your network using a VPN is that it also reduces all security risks from third parties. This is particularly beneficial for corporate employees who work from their respective homes, while in transit using mobile phone Wi-Fi and public networks, and most importantly, while sending and receiving confidential corporate information from third-party clients.
VPNs platforms like ExpressVPN and NordVPN are known for securely masking the user’s IP address, hence making them immune to all kinds of network security threats on the internet. They also offer high speed and do not track user activity or keep logs of traffic and visited sites. These features are what make the VPN technology a recommended security solution to date.
Asides the above-mentioned features, however, next-gen VPN platforms like Switcherry and Hotspot Shield are looking to implement even more advanced technology to their platforms. These technologies include SDPs and SWGs.
Software-Defined Perimeter (SDP) creates an isolated network connection for different users within the same network. Secure Web Gateway (SWG), on the other hand, blocks user access to malicious traffic.
Hence, no doubt the implementation of these technologies to the already existing security solutions of VPNs will lead to a strengthened security solution with a solid zero-trust framework.
This points to the fact that the Virtual Private Network technology is not going away any soon and that it’s also making changes and adjustments to contain the fast-advancing next-gen cyber threats.
Array of Firewalls
Firewalls can be understood as virtual gates, which act as a security parameter between your network and the internet. There are different kinds of firewalls catering to different user needs, such as managing private networks, blocking unauthorized access, blocking access to malicious websites and links, as well as allowing authorized traffic to access the internet with all security measures taken care of.
Some of the popular kinds of firewall are:
- Proxy Firewall
- Next-Generation Firewall
- Threat-Focused Firewall
- Stateful Inspection Firewall
- Unified Threat Management Firewall
Setting Cyber Security KPIs
This is a rather complex yet compelling method of ensuring the safety of your network. All organizations/individuals must have a defined set of Key Performance Indicators (KPIs) for tracking and improving the security of their public and private networks. One must track important KPI factors, such as Mean Time To Detect (MTTD) and Mean Time To Contain (MTTC) to study and reflect on the effectiveness of the security measures undertaken from time to time.
Given the extensive nature of threats to network security, individuals, as well as organizations, need to keep track of their cybersecurity indicators at all times. They must also invest in the latest upgrades and most effective security solutions to safeguard their networks.
