Defending Cyber-Attacks by Isolating Attacks at the Point of Entry
As security breaches become more frequent and complex, the role of a cyber attacker has also evolved. The main goal of an attacker is to gain access and then make use of the gained access to cause maximum damage, while an organization aims to protect itself.
Micro-segmentation plays a crucial role in defending a company’s infrastructure. With the use of micro-segmentation, security architects can logically separate the data center into segments, and then build security rules to provide services for each distinct segment. As a result of its capacity to limit the attack to just that sector, a company’s resilience to attack can be considerably improved.
The three main methods of micro-segmentation are as follows:
Network-based: Creates segments primarily using subnets, VLANs, or other tagging technologies
Hypervisor-based: In this case, to impose micro-segmentation, hypervisors build an overlay network. This may have a different range of coverage depending on the hypervisor utilized and the customers use of computational resources
Host-based: To enable distributed policy control, this is accomplished by utilizing the native firewall capabilities included in the operating system. In data centers, clouds, and hybrid environments, host based micro-segmentation can be implemented via an agent
Organizations must move security policy controls within the data center and cloud environments and restrict the amount of access each application requires to lower the attack surface. Policies governing internal security aid in limiting the impact of attacks by preventing lateral propagation.
There is no “one size fits all,” and the deployment method to be employed will only be determined by the customer’s environment. We must be in tune with business risks and the best ways to limit or minimize them. The chosen solution must be based on zero-trust security architecture and provide a single point of control for managing, orchestrating, and automating resource access policies throughout the environment.
The need for segmentation is clear, as companies continue to invest in cloud and other web-based services. The incorporation of micro-segmentation and software-defined security is a powerful tool that can enable better protection of data in the enterprise. For companies that rely heavily on the internet to conduct business, creating an effective security architecture is essential.
Not surprisingly, the rate of cyber-attacks on enterprise networks is multiplying rapidly. From ransomware and phishing attacks to hardware-based threats, it’s getting more challenging for enterprises to secure their networks effectively. Over the past decade, cyber security has emerged as one of the most pressing matters of the day. And with good reason! No business can afford to be complacent about the threats posed by hackers. You must protect your assets from cyber attacks.
Attacks are increasing. That is true. Instead of “if or when,” the question is “who today?”
The fact that there isn’t a solid answer for cybersecurity, is the largest challenge for many businesses. With layered network design and segmentation, like what we’ve been learning here today, it is best to defend against cyber-attacks.
Be Prepared. Be Protected.
