With increasing remote or hybrid work models, network security became more important than before. Implementing different network security solutions is highly suggested to provide secure and safe access. While a variety of cyber threats and cyberattacks are gaining diversity and becoming riskier, various network security solutions offer more secure and safer options.
Since there are different types of network security solutions, learning and deciding which ones you need became an important consideration. All these security solutions are efficient, but some are more suitable for certain companies than others. Let’s take a look at these solutions and see how they work.
1) SASE – Secure Access Service Edge
One of the network security solutions that you can implement is SASE. It is a cloud-based multitool that allows you to combine your cloud-based firewalls, software-defined networks, and cloud access service brokers into a single zero-trust paradigm.
SASE is not a technology but a whole network architecture framework that combines cloud-native security technologies — particularly SWG, CASB, ZTNA, and FWaaS — with wide area network (WAN) capabilities to securely link users, systems, and endpoints to applications and services anywhere.
While traditional infrastructures use the “hub-to-spoke model, SASE allows users to access resources hosted in centralized data centers from diverse locations. Users can get access to this core data center via a localized private network or a VPN, depending on the design of your company’s network.
Let’s see how a SASE architecture can help you with your network security. See the reasons below to learn SASE’s benefits.
- Using the SASE framework to implement data protection policies protects sensitive data from security breaches and misuse.
- You get additional security and insight into your network with comprehensive content inspection incorporated into the SASE solution.
- It allows you to increase performance by making your data available globally. You can simply access resources wherever they are with a cloud infrastructure.
- Using a single platform instead of buying and managing several point solutions will reduce your costs and help you to save your costs.
2) Software-Defined Perimeter – SDP
Software-defined perimeter is a security framework that regulates resource access based on identity. The SDP method aims to make the network perimeter software-based rather than hardware-based. It allows you to hide your Internet-connected infrastructure, while authorized users can access the infrastructure, third parties and attackers can not see it.
Instead of the application layer, SDP creates a virtual barrier around firm assets at the network layer. This distinguishes SDP from other access-based policies that limit user access permissions while allowing broad network access. Also, SDP authenticates both devices and user identity.
As it is one of the best network security solutions on the market, SDP offers a variety of advantages like being easy to manage or providing security. Since SDP does not automatically allow users to access every resource even if they are authenticated, each user is allowed to access resources or tools they need.
Furthermore, since SDP is not hardware-dependent it can be implemented locally or in the cloud. It allows end-users to connect from any location resulting in lower cost, flexibility, and scalability.
3) Firewalls
A firewall is a network security device that filters incoming and outgoing network traffic and monitors them according to security regulations specified by an organization. It essentially puts a layer of protection between a system and harmful attackers.
There are three different types of firewalls; software, hardware, and both. A software firewall is a program that is installed on each device that controls activity via port numbers and programs, whereas a hardware firewall is a piece of equipment that is located between your network and gateway.
Firewalls are designed to thwart malware and application-layer attacks. To prevent attacks, firewalls carefully evaluate incoming or outgoing traffic using predefined policies and filter traffic from unsecured or risky sources.
A Firewall can be used to prevent unauthorized remote access. It protects your device and personal information from attackers. You can use a Firewall to restrict inappropriate content and it also offers you an option to restrict access to specified websites.
It defends you against the spread of ransomware. Furthermore, it maintains the confidentiality of your personal information, such as your login credentials, passwords, or sensitive data.
Final Words
Even if cyber threats are evolving and adapting to new security solutions, these kinds of protections do a good job to let you protect your data and secure your online activity.
In this modern and always-changing world, you should always consider your cybersecurity, that is why it is better to take action before being one of the victims of cyberattacks.
