The importance of data in business growth is imperative; however, network holds equal importance as it facilitates the flow of data. This makes it important to secure the organizational network to protect data as well as secure network endpoints. Thus, organizations need to implement effective network security and network visibility strategy.

Here is a list of network security tools that can help organizations in securing their network against security attacks:

  • Access Control: The best way to control damage caused by threat actors is to keep them out of the network. In addition to limiting the access of outside threats, it is equally important to take care of insider threats. Access control tools help organizations in keeping out threat actors and limiting user access to network areas that directly apply to user’s responsibilities.
  • Anti-Malware Software: Malware including virus, trojans, worms, keyloggers, spyware, etc. are designed to spread across computer systems and infect an organization’s network. Anti-malware tools assist organizations in identifying, controlling and resolving malware infections to minimize the damage caused to network.
  • Anomaly Detection: In order to detect anomalies in a network, it is first important to understand usual operations of the network. Network security tools such as Anomaly Detection Engines (ADE) allow organizations in analyzing a network, so that when and if any anomaly or network breach occurs, the IT team will be alerted quickly enough to limit the damage.
  • Application Security: Most cyber attackers consider applications to be a defensive vulnerability that can be exploited to cause network disruptions. Including application security tools can help organizations in establishing security parameters for applications.
  • Data Loss Prevention (DLP): Threat actors tend to use humans to cause data breach or network security breach. DLP technologies and policies help in protecting the employees and other users from misusing or possibly compromising sensitive data or allowing data flow out of the network at any of the endpoints.
  • Email Security: Email security tools are another set of network security tools that help organizations in minimizing human-related security weaknesses. Hackers or cyber criminals persuade employees to share sensitive information or inadvertently download malware into targeted network via phishing strategies. Email security tools assist organizations in identifying dangerous emails and blocking attacks.
  • Endpoint Security: Bring Your Own Device (BYOD) culture has become highly integrated in organizations to an extent that it has become tough to distinguish between personal and business devices. Cyber attackers take this as an opportunity and attack personal devices to launch a network security attack. Endpoint security tools add a layer of defense between remote devices and business networks.

Why Organizations Need Intent-Based Networking?

By

On June 29, 2020

In Networking

Intent-based networking or IBN applies deep intelligence and intended state insights to networking. These insights replace the need to manually configure the network. In general terms, the administrators can send a request with desired outcomes or intent to the network instead of coding individual tasks manually. The network’s software understands the intent and decides on the steps that need to be taken based on AI and Machine Learning.

IBN has some advantages over traditional and software-based networking which makes it an ideal choice for organizations. Following are some reasons why organizations need IBN:

Reduction In Manual Tasks: In the case of traditional networking, the administrator has to manually reconfigure every task with changing business needs. However, in the case of IBN, the administrator feeds the business needs to the network and the network analyzes these needs, verifies if a change in configuration will solve the need, suggests configuration options, and makes the required changes.

Faster Troubleshooting And Resolution: An intent-based networking system keeps on monitoring itself regularly. This helps in identifying any issues as soon as they arise. Also, IBN has the capability to repair itself without any human intervention using Machine Learning to find suitable solutions.

Reduced Risk Of Non-Compliance: Since the intent-based network is constantly monitoring and repairing itself, it ensures that the system is always in compliance with any policies set by the administrator.

Better Security: Looking for security threats is a part of regular monitoring conducted by an intent-based network. It monitors encrypted traffic as well to be aware of any possible threat. This results in immediate identification and containment of any security breaches to ensure data and network security of the organization.

Optimized Analytics: Understanding network performance is essential for making efficient decisions and predicting network outcomes for minimal risk. IBN regularly collects data about itself which can be used to deduce important information about network performance.

Rapid Implementation Of Business Goals Into Network Configurations: The main advantage of using intent-based networking is that it readily modifies the network configuration as per high-level business goals. The administrator can easily choose from vetted configuration options suggested by IBN saving the time needed for manual planning, testing, and configuration. Faster implementation of business goals into network configuration results in higher ROI.
