Active network security

Introducing active network security strategy is a good network security preparation status before any attack occurs.

Most organizations take it as a positive network security method, once an attack occurs, ready to do some movements. Or, take a passive method to take action after the attack is completed. Active network security strategy is to take action before any attack occurs; this is a good network security preparation state.

Policies, tools and practices constituting active network security measures

The creation and review of security tools, agreements, strategies, and practices are often a process that is good for forgetting. However, the world is changing. Active way is to continuously review all of this, focus on new threats, new tools and new ideas, and update all content frequently. The same is true for training. The “course” of network security awareness and related employee training should be actively reviewed at least every quarter.

Moral hacker

Instead of waiting for attack, it is better to make hacker simulation attacks. After certified moral hackers explore defense, find vulnerabilities and defense weaknesses. These aggressive security researchers use the same methods and tools as malicious attackers. Red Squad / Blue Team Exercise, Penetration Test and Other Simulation Enables your employees to learn from cyber attacks without truly attack.

Intelligent automation

Use tools that can inspect things that are happening on the network and automatically respond. The active method means that it has been locked and loaded as many fixes as possible. Smart software can provide 24×7 all-weather search violations and abnormal behavior, ready to isolate and repair when certain things have occurred, which is offense rather than defensive.

Zero trust

Using a proactive method, you can lock the door when the intruder is detected. But by active methods, you can lock the door before they arrive. Zero Corster strikes to verify and authorize each device, applications, and users of each resource. For attackers, even if they can steal passwords, they will still find that the door is locked because they have no authorization equipment. This method of actively locking the door through zero trust model is more important because many remote staff use home office. They use equipment in networks that are unknown in physical security unknown space and quality.

The zero trust model is dynamic, requiring monitoring, learning, and adaptation on the basis of continuous (active).

Proactive and passive in endpoint monitoring

Active security means monitoring active endpoint monitoring. With the popularity of Internet accessories, cloud infrastructure, and remote work, it is more important than ever. Automated endpoint monitoring to maximize local security of each device.

Behavior indicator

Active and passive network security requirements look for compromise indicators – indicating signs of violations and network crimes. But active network security looks for behavioral indicators (IOB), that is, the actions taken by users.

For example, some people may find that the business data is downloaded to an external storage device, or upload code to an unknown cloud service. IOB may be permission change or network on the personal desktop PC switches from internal Wi-Fi to mobile broadband hotspots. By collecting hundreds of such information, you can understand the vulnerability of your organization from the perspective of behavior. It can also be changed at the smallest interrupt. For example, you can find a more secure option in advance using a U disk, thus preparing for the decision to actively disable the U disk connection. You can also isolate a specific device or endpoint to closely monitor when employee behavior is in danger.

Active and passive is a mentality

Active network security is a wide range of overall methods. Not only involves specific methods and practices, but also involves an offensive network security mentality. After all, why should you wait until you have been attacked? In contrast, action can be taken immediately and prevent attacks.
