In the context of cybersecurity, network automation aids in detecting and responding to threats, vulnerabilities, and breaches in real-time, thereby enhancing the overall security posture of an organization. Let’s explore the roles of automation and security in network management.
The Power of Network Automation
Network automation involves the use of software to manage, control, and perform network operations, replacing previously manual procedures. These operations span a wide range of tasks, from basic network mapping and device discovery to advanced diagnostic and security functions.
A standout feature of network automation is its ability to manage distributed, multi-vendor networks. This significantly reduces manual misconfigurations, which are often the cause of most security breaches and network downtime. Tools such as those provided by HP Network Automation gather detailed information about network devices and record configuration changes. 1 Notifications of these changes offer immediate visibility into planned, unplanned, and unauthorized modifications.
Organizations can also leverage network automation to implement powerful access control list (ACL) automation and management capabilities. With ACL templates, companies can quickly respond to emerging threats and vulnerabilities, reducing complexity and ensuring consistency across the network. With the right network automation tool, an entire network can be managed on a single instance, providing scalability and redundancy where necessary.
Advancing IT Workflows
Network automation also plays a pivotal role in advancing IT workflows, particularly those that were once manual processes. Real-time configuration and asset tracking, policy compliance, SNMPv3 and IPv6 management, and automated software image management are a few of the many benefits that network automation brings to IT operations. All these functionalities help in detecting configuration and asset information changes, performing rapid troubleshooting, managing network compliance, and updating images and feature sets.
Enhancing Network Security
In the realm of network security, automation provides a robust defense mechanism. By automating routine tasks, security teams can focus their efforts on more complex threats. Automation can help identify vulnerabilities and threats in real-time, streamline patch management, and enforce security policies consistently across the network.
The automation of security policies and the immediate detection of non-compliance issues further enhance the security profile of an organization. Automated remediation of devices that violate standards is another significant advantage, as it speeds up both internal and external audit processes.
Network Automation Tools
Several tools are available to facilitate network automation and security. For instance, IBM Cloud Pak for Network Automation offers a comprehensive suite of capabilities to design, deploy, manage, and automate network resources in a cloud-native environment. 2 Similarly, solutions like Terraform allow for automating the deployment of networks in a cloud environment, making it a powerful tool for implementing Infrastructure as Code (IaC).
Cisco’s DNA Center Automation, on the other hand, provides a centralized, intuitive dashboard to design, provision, apply policy, and assure network connectivity services with full visibility and context of users and devices on the network. Moreover, Cisco and Python’s advanced network automation capabilities offer a myriad of possibilities for network engineers to automate their daily tasks.
