Threat remediation identifies cyber threats and devises a plan for managing the issues effectively to make the organization cyber-resilient.
FREMONT, CA: The enterprise network is complex and probably depends on several connected endpoints. While this is good for business operations and makes enterprise workflow seamless to maintain, it also presents a hurdle for security. The issue is that the flexibility of movement within the network means that if a hacker gains access to the network, they can often move around and cause harm, often without the knowledge. Here is more about what constitutes a network attack and what firms can do to contain threats.
Segregate the Network
A basic part of network security is segregating a network into zones based on security needs. This can be done utilizing subnets within the same network or generating Virtual Local Area Networks (VLANs), each of which behaves like a completely different network. Segmentation limits the potential effect of an attack to one zone and needs attackers to take special measures to penetrate and get access to other network zones.
Enterprises should not allow network users to access the Internet unchecked. Passing all the requests through a transparent proxy and using it to control and monitor user behavior is essential. Firms must ensure that a human can perform outbound connections and not a bot or other automated mechanism. Whitelisting domains can ensure corporate users can only access websites firms have explicitly approved.
Use Network Address Translation
Network Address Translation (NAT) allows firms to translate internal IP addresses into addresses accessible on public networks. Firms can use it to connect several computers to the Internet, harnessing a single IP address. This offers an extra layer of security because any inbound or outgoing traffic has to go through a NAT device. Some IP addresses make it complex for attackers to understand which host they are connecting to.
Using Deception Technology
No network security measures are completely successful, and attackers will succeed in penetrating the firm’s network. Recognizing this and placing deception technology in place creates decoys across the network, tempting attackers to hack them and let firms observe their plans and techniques.
