Rather than trying to manage the growth of networks in a static environment, modern security teams are focusing on solving the problem of growing networks in a dynamic environment without compromising security. Security-driven networking is the only way to ensure that a changing climate will not be a risk to your network. Read on to learn more about moving target defenses, Active defenses, and Cloud-based tools. It is the future of network security, and it is time to take action.
IoT
IoT security is crucial because the connected world is full of potentially vulnerable devices. Hackers are already targeting these devices to steal valuable information. The impact of such attacks varies, and the severity largely depends on the type of system and the information it contains. For example, attacks on connected medical devices can result in serious health consequences, while those on refrigeration systems can endanger the viability of a drug. Moreover, attacks on critical infrastructure can be disastrous.
The first step in IoT security is to secure all network connections. This includes encryption and authentication. Encryption is the best option for protecting data while traveling over a network. Therefore, both authentication and encryption are essential for IoT security. Additionally, you can use separate encrypted connections between devices. Both of these measures can help protect IoT devices from credential-based attacks. Once installed, these steps can help ensure the safety of connected devices.
Cloud-Based Tools
As organizations increasingly move to the cloud, the need for security-driven networking has become critical. With a security-driven network, data is secured along its entire path from origin to destination, ensuring a seamless handoff across multiple network domains. Cloud-based tools for security-driven networking enable organizations to meet this need with ease. This article will examine some of the most critical aspects of this new approach to security.
Using cloud-based tools for security-driven networking can help organizations prevent data breaches while protecting sensitive data from internal and external threats. Cloud security solutions can also help to minimize the risk of misconfigurations and errors that could compromise applications. Unfortunately, many misconfigurations occur during the development process when customers are responsible for configuring the cloud and securing applications. Unfortunately, these missteps are common, particularly in complex environments, and making mistakes is easy.
Active Defenses
Active defenses are the actions an organization takes in response to an attack. These actions help mitigate or contain an attack by identifying the source and preventing it from spreading. They can also be offensive, such as striking back at an attacker. Such actions are permitted by law enforcement and the military. They provide valuable threat intelligence that can help prevent a similar attack. But active defenses also carry risks. These dangers can negatively impact innocent parties.
Using an active defense to prevent an attack is essential. This is because it can take down the source of an attack. For example, a botnet can be stopped by seizing the attacker’s computer or disrupted by disabling the C2 servers that control the botnet. In the case of Coreflood, active defenses were used to take down the botnet, which neutralized the attacker’s bots and removed the malware from the victim’s computer.
Moving Target Defenses
The evolving nature of attackers has made it necessary for defenders to adapt to these changing attack profiles. Advances in polymorphism, packing, and encryption have made it possible to shift attack profiles and deceive detection quickly. As a result, defenders must identify every viable attack construct and constantly adjust their defenses to keep up. On the other hand, attackers can reuse relatively small attacks. This is where moving target defenses come into play.
The Moving Target Defense (MTD) is an advanced technology that increases the difficulty of attacks on enterprise networks. Traditionally, most networks are static and give attackers an advantage over attackers. A moving-target defense system makes the network look chaotic and random by continuously changing the network configuration. It also explicitly captures network goals and the functionality required to achieve them. This makes attackers more difficult to detect and deter further attacks.
Migrating to Security-Driven Networking
Security-driven networking (SDN) is a modern approach to network infrastructure. It incorporates security into networking and maps security functionality to network requirements while maintaining network performance and integrating into existing management tools. It has several benefits, including protecting sensitive data while enabling network administrators to manage their environments better. It allows organizations to secure mobile devices and address the ever-growing threat landscape. Security-driven networks are also highly scalable and can be implemented in minutes rather than years.
Fortinet, an infrastructure security leader, is an excellent example of the advantages of security-driven networking. By combining networking and security, SDN enables organizations to manage their networks in an automated, consistent way. This approach simplifies management and minimizes risk, allowing organizations to invest in security without affecting operations. In addition, SDN-based solutions help businesses reduce their IT budget by allowing IT professionals to focus on core business activities.
